In the field of monitoring security, a cross rod is generally arranged at an intersection or a place where security equipment needs to be arranged, and a three-dimensional universal joint is installed and fixed on the cross rod through a holding rod bracket; then the monitoring camera is arranged on the three-dimensional universal joint; the shooting picture of the monitoring camera is adjusted through the three-dimensional universal joint so as to obtain better monitoring effect and accuracy of the shooting picture.

Wherein, the three-dimensional universal joint generally comprises a fixed base fixed on the pole support; an intermediate regulator rotatably connected with the fixed base; in general, the middle adjusting body can rotate with the fixed base, so that the pitching of the monitoring camera, namely the inclination angle of the camera, is adjusted; in addition, one side of the middle adjusting body, which is away from the fixed base, is rotatably connected with the connecting base; that is, after the pitch angle of the intermediate adjusting body is adjusted, the left and right inclination angle can be adjusted by the rotation of the connecting base and the intermediate adjusting body.

It will be appreciated that after the adjustment of the monitor camera's frame is completed, the monitor camera typically needs to be fixed so that a frame at a proper angle can be monitored. For facilitating the angular adjustment and fixation. In general, an arc-shaped chute is arranged on one of the middle adjusting body or the fixed base, a fixed screw is arranged on the other of the middle adjusting body or the fixed base, the fixed screw penetrates through the arc-shaped chute, and when the monitoring angle is adjusted, the fixed screw slides in the arc-shaped chute; when the angle is adjusted to a proper angle, the monitoring camera is screwed on the screw rod through the nut and fastened, so that the shooting angle of the monitoring camera is fixed.

However, in actual use, the connection between the nut and the fixing screw may be loosened due to vibration caused by passing of the vehicle, vibration caused by road construction, or wind blowing, so that rotation occurs between the middle adjusting body and the fixing base, the angle and the picture shot by the monitoring camera change, and the picture to be monitored is inaccurate.

Fig. 1 is a schematic overall structure of a direction holding structure according to an embodiment of the present utility model, and fig. 2 is a schematic structural diagram of a single universal joint in the direction holding structure according to an embodiment of the present utility model.

Referring to fig. 1, an embodiment of the present utility model provides a direction holding structure 10 including: at least two three-dimensional gimbals 110 and a rigid connection 120 arranged side by side.

In the embodiment of the present utility model, the inclination directions of the intermediate adjustment bodies 112 of the adjacent two three-dimensional universal joints 110 are opposite.

Specifically, referring to fig. 1 and 2, the three-dimensional universal joint 110 may include a base 111, an intermediate adjusting body 112, and a connection seat 113.

In this embodiment, the base 111 may be used in connection with a support rail, for example, the base 111 may be connected to a rail of a traffic light. The intermediate adjusting body 112 may be rotatably connected with the base 111, thereby adjusting a tilt angle of the monitoring camera. The connecting seat 113 is used for being connected with the monitoring camera, and the connecting seat 113 is also rotatably connected with the middle adjusting body 112, so that the rotation of the connecting seat 113 can adjust the horizontal inclination angle of the picture shot by the monitoring camera.

It will be appreciated that in embodiments of the present utility model, the three-dimensional gimbal 110 may be two, three, or more arranged side-by-side. Referring to fig. 1, in the embodiment of the present utility model, a case where three-dimensional universal joints 110 are two is described as a specific example.

In the embodiment of the present utility model, the inclination directions of the intermediate adjustment bodies 112 of the adjacent two three-dimensional universal joints 110 are opposite; here, it should be noted that, in the embodiment of the present utility model, the inclination direction of the intermediate adjusting bodies 112 of the adjacent two three-dimensional universal joints 110 may specifically be the pitch direction of the intermediate adjusting bodies 112; i.e. the tilt direction of the monitoring camera after the monitoring camera has been mounted. For example, referring to fig. 1, one of the intermediate adjustment bodies 112 may be inclined in the direction shown by x in fig. 1; the tilting direction of the other intermediate adjustment body 112 may be tilted in the direction shown by y in fig. 1.

In a specific application scenario, for example, at an intersection, a cross bar that generally supports the monitoring device spans over a road surface and is perpendicular to an extending direction of the road surface. In addition, the monitoring device is usually required to monitor the conditions on the road surfaces on both sides of the cross bar, and at this time, one monitoring device is required to shoot on the road surface on one side facing the cross bar; another monitoring device is required to shoot the road surface facing the other side of the cross bar; that is, the tilting directions required for the two monitoring devices are opposite. In some examples, the two middle adjusting bodies 112 may be inclined to both sides of the cross bar with reference to a vertical line or a vertical direction perpendicular to the cross bar.

In the embodiment of the present utility model, referring to fig. 1, the rigid connection member 120 is disposed between two adjacent three-dimensional universal joints 110, one end of the rigid connection member 120 is connected to one of the two intermediate adjustment bodies 112, and the other end of the rigid connection member 120 is connected to the other intermediate adjustment body 112 of the two intermediate adjustment bodies 112.

Specifically, in the embodiment of the present utility model, the rigid connection member 120 may be made of a metal material or an alloy material such as stainless steel, cast iron or aluminum alloy. The rigid connection 120 has a certain rigidity strength, and is not easy to bend and deform.

When specifically provided, the base 111, the intermediate adjusting body 112, and the connecting base 113 may be formed by folding or punching a sheet metal member. In a specific use, the pitch angle of the monitoring device (e.g., camera) may be adjusted by the intermediate adjustment bodies 112, and then the rigid connection 120 is connected between the two intermediate adjustment bodies 112.

Fig. 3 is a schematic diagram illustrating stress analysis of a direction-holding structure according to an embodiment of the present utility model.

It will be appreciated that, referring to fig. 3, in the embodiment of the present utility model, after the monitoring device is mounted on the connection base 113, one of the intermediate adjusting bodies 112 is inclined in the x direction in the drawing; the other intermediate adjustment body 112 is inclined in the y direction in the figure so that the monitoring directions of the two monitoring devices are opposite. Immediately after the initial installation, the inclination angle of the intermediate adjustment body 112 may be fixed by a screw between the intermediate adjustment body 112 and the base 111.

It will be appreciated that after the three-dimensional universal joint 110 is used for a period of time, the nuts of the screws may be loosened due to vibration of the device, wind, rain, etc., so that the friction between the nuts and the intermediate adjusting body 112 and the base 111 is insufficient, and at this time, the intermediate adjusting body 112 may rotate due to the gravity influence of the monitoring device. For example, referring to fig. 3, an intermediate adjustment body 112 that is tilted in the x-direction may rotate in the e-direction to cause the monitoring device to sag or drop. An intermediate adjustment body 112 that is tilted in the y-direction may rotate in the z-direction causing the monitoring device to sag or drop.

At this time, with continued reference to fig. 3, one intermediate regulator 112 rotating in the e-direction pulls the rigid link 120 in the a-direction at the connection of the rigid link 120, i.e., one intermediate regulator 112 rotating in the e-direction provides a pulling force in the a-direction to the connection C of the rigid link 120. Since the rigid connection member 120 is of a rigid structure, a tensile force in the a direction is transmitted to a connection position (refer to a position D shown in fig. 3) of the rigid connection member 120 and the other intermediate adjustment body 112 through the rigid connection member 120, that is, the rigid connection member 120 has a tensile force in the a' direction shown in fig. 3 to the other intermediate adjustment body 112 at the position D.

It can be understood that the two three-dimensional universal joints 110 monitor images in two different directions due to being installed on the same road section or the same beam; thus, the environmental factors to which the two three-dimensional universal joints 110 are subjected can be considered the same. At this time, with continued reference to fig. 3, at D of the other three-dimensional universal joint 110 and the rigid connection 120, the other intermediate adjustment body 112 has a tensile force to the rigid connection 120 shown in the direction b in the drawing; the rigid connection 120 will transmit the pulling force shown in direction b of the drawing to C, thereby creating a pulling force shown in direction b' of fig. 3 for the intermediate adjustment body 112.

As before, since the two three-dimensional universal joints 110 are in the same environment, the sagging or drooping forces of the two intermediate adjustment bodies 112 are the same, resulting in zero resultant force at the position where the two intermediate adjustment bodies 112 are connected by the rigid connection member 120, so that sagging or drooping of the intermediate adjustment bodies 112 can be effectively avoided.

In some examples, it may also be understood that: when the two intermediate adjustment bodies 112 having opposite inclination directions have a tendency to sag or drop, the sagging directions of the two intermediate adjustment bodies 112 having opposite inclination directions are opposite. As the rigid connection 120 connects the two intermediate adjustment bodies 112. The rigid connection 120 forms two connection points with the two intermediate adjustment bodies 112, for example connection point C and connection point D in fig. 3; it will be appreciated that the two points define a straight line, and since the rigid connection 120 is of rigid structure, it will not bend and deform, and therefore, the positions of the connection point C and the connection point D are positioned on a straight line, so that sagging or drooping of the two intermediate adjustment bodies 112 can be avoided, and sagging of the two monitoring devices with opposite tilting directions can be avoided.

As a specific example, in the embodiment of the present utility model, the monitoring angle of the monitoring camera may be adjusted to a desired angle by the intermediate adjusting body 112, and then pre-fixed by a screw, so as to position the inclination angle of the intermediate adjusting body 112. Thereafter, the rigid connection 120 may be connected between the two intermediate adjustment bodies 112, for example, by welding with the two intermediate adjustment bodies 112, respectively.

The present utility model provides a direction holding structure 10 and a monitoring device supporting means for holding the tilt directions of three-dimensional universal joints 110 for supporting two adjacent monitoring devices in opposite directions; that is, the monitoring directions of two adjacent monitoring devices are opposite; a torsion bar is then connected to the intermediate adjustment body 112 of two adjacent three-dimensional universal joints 110 (i.e., the adjustment body that adjusts the tilt direction of the monitoring device). Thus, when either or both monitoring devices sag or drop, the presence of the rigid connection 120; the intermediate adjusting body 112 of the three-dimensional universal joint 110 corresponding to the monitoring device with sagging or sagging tendency pulls the three-dimensional universal joint 110 corresponding to the other monitoring device through the rigid connecting piece 120; since the inclination directions of the middle adjusting bodies 112 of the other three-dimensional universal joint 110 are opposite, the other three-dimensional universal joint 110 can provide a reverse acting force for the rigid connecting piece 120, so that the rigid connecting piece 120 can provide a reverse pulling force for the middle adjusting bodies 112 of the three-dimensional universal joint 110 with sagging or falling trend, the three-dimensional universal joint 110 is kept at the original position without sagging or falling, the shooting picture of the monitoring equipment is kept unchanged, and the accuracy of monitoring the shooting picture can be effectively ensured.

Referring to fig. 2, in the embodiment of the present utility model, two adjacent sides of the intermediate adjusting bodies 112 are provided with opposite adjusting arms 1121, and torsion holes 1122 are provided on the adjusting arms 1121; the rigid connector 120 is disposed through torsion holes 1122 in the two adjustment arms 1121.

Specifically, as described above, in the embodiment of the present utility model, the intermediate adjusting body 112 may be formed by stamping or bending a metal plate, so that the two adjusting arms 1121 may be integrally formed with the intermediate adjusting body 112.

In some examples, torsion aperture 1122 may be integrally formed in adjustment arm 1121 or may be formed in adjustment arm 1121 by a secondary process performed on adjustment arm 1121.

It will be appreciated that referring to fig. 1, in the embodiment of the present utility model, two three-dimensional universal joints 110 are shown as a specific example in a side-by-side arrangement; thus, in the embodiment of the present utility model, the torsion hole 1122 may be formed in one of the adjacent side walls of the two intermediate adjustment bodies 112.

Of course, in some examples, torsion holes 1122 may be provided in both adjustment arms 1121 of intermediate adjustment body 112 to facilitate the installation of the universal joint. In this way, the placement and connection of the rigid connection 120 may also be facilitated when there are three or more three-dimensional universal joints 110 placed side by side.

In the embodiment of the present utility model, by providing the torsion hole 1122 on two adjusting arms on the adjacent side of the two middle adjusting bodies 112, the rigid connecting piece 120 is inserted into the torsion hole 1122, so that the connection between the rigid connecting piece 120 and the two middle adjusting bodies 112 can be facilitated, and the installation efficiency of the direction keeping structure 10 provided in the embodiment of the present utility model is improved.

It can be appreciated that, as described above, in the embodiment of the present utility model, the use environment of the monitoring device may have factors such as vibration, wind, rain, and the like; these factors may cause the rigid connector 120 that is threaded into the torsion aperture 1122 to slide out of the torsion aperture 1122.

In an alternative example of embodiment of the present utility model, referring to fig. 5 and 6, the direction holding structure 10 further includes: a fixing member 130, wherein the fixing member 130 is positioned at one side of the two adjusting arms 1121 opposite to each other; the fixing member 130 is used to connect with an end of the rigid connection member 120 to fix the rigid connection member 120 within the torsion hole 1122.

Specifically, in the embodiment of the present utility model, the fixing member 130 may be a buckle member or a clip spring. For example, in some examples, a slot may be provided in the peripheral wall of the rigid connector 120, the clip spring snaps into the slot, and then a portion of the clip spring abuts against the inner sidewall of the adjustment arm 1121, thereby preventing the rigid connector 120 from sliding out of the torsion hole 1122.

In some examples, a snap hole may be formed at the end of the rigid connector 120 in the radial direction, and then the snap member may be inserted into the snap hole, and a portion of the snap member may abut against the inner sidewall of the adjustment arm 1121, so that the rigid connector 120 may be prevented from sliding out of the torsion hole 1122.

It should be noted that, the inner side wall of the adjusting arm 1121 may specifically refer to a side wall of two adjacent adjusting arms 1121 of two adjacent intermediate adjusting bodies 112 opposite to each other.

In the embodiment of the present utility model, the fixing points are disposed on the opposite sides of the two adjusting arms 1121, and the fixing member 130 is connected to the end of the rigid connection member 120; thus, the fixing member 130 can block the end of the rigid connector 120, so that the rigid connector 120 can be prevented from sliding out of the torsion hole 1122, and the effectiveness of maintaining the shooting angle or shooting direction of the monitoring device is ensured.

Referring to fig. 4 to 6, in an alternative example of the embodiment of the present utility model, both ends of the rigid connection member 120 are provided with threads 121, and the fixing member 130 is connected with the threads 121 of the rigid connection member 120;

the direction holding structure 10 further includes: the spacer 140, the spacer 140 is located between the fixing member 130 and the adjustment arm 1121.

Specifically, in embodiments of the present utility model, the rigid connection 120 may be a rigid rod-like structure; external threads 121 may be provided at both ends of the rod. In other words, in the embodiment of the present utility model, both ends of the rigid connection member 120 may be processed into a cylindrical shape or an elliptical cylindrical shape, so that the external screw thread 121 is conveniently disposed.

In particular embodiments, the securing member 130 may be a nut that engages the internal threads 121 and the external threads 121 on the rigid connector 120 to secure and tighten the rigid connector 120 and the adjustment arm 1121.

In the embodiment of the present utility model, the pad 140 may be a metal pad 140, a silica gel pad 140, or a rubber pad 140.

In the embodiment of the utility model, the screw thread 121 is arranged at the end part of the rigid connecting piece 120, and then the gasket 140 is arranged between the fixing piece 130 and the adjusting support arm 1121, so that after the fixing piece 130 is screwed, the friction force between the surface of the adjusting support arm 1121 and the fixing piece 130 can be increased, and the fastening stability of the rigid connecting piece 120 is ensured.

In some alternative examples of embodiments of the present utility model, the orientation maintaining structure 10 further includes: an adhesive (not shown) is provided at least between the inner wall of the torsion hole 1122 and the peripheral wall of the rigid connector 120.

Specifically, in the embodiment of the present utility model, the adhesive may be formed after curing an adhesive, and the adhesive may be, for example, phenolic resin, epoxy resin, latex, or metal glue. In a specific arrangement, the rigid connection member 120 may be first inserted into the torsion hole 1122, and then an adhesive may be poured into the inner wall of the torsion hole 1122 from the fit gap between the rigid connection member 120 and the torsion hole 1122.

In some alternative examples, the adhesive covers the fixture 130 and the shim 140.

With continued reference to fig. 2, in the embodiment of the present utility model, the torsion holes 1122 are plural, and the plural torsion holes 1122 are arranged at intervals along the adjustment rotation direction of the adjustment arm 1121.

Specifically, in embodiments of the present utility model, the adjustment arm 1121 or the intermediate adjustment body 112 has a fixed rotational axis/axis when rotated relative to the base 111; referring to fig. 2, in the embodiment of the present utility model, the plurality of torsion holes 1122 are arranged along an arc/arc, and the center of the arc in which the plurality of torsion holes 1122 are arranged is located on the rotation axis or rotation axis of the adjusting arm 1121 or the intermediate adjusting body 112 with respect to the base 111. In this way, the torsion holes 1122 on two adjacent intermediate adjusting bodies 112 are all arranged in an arc shape, and in addition, the circle centers of the arranged arcs of the torsion holes 1122 are the same, and the distances from the circle centers are the same; when the two adjacent intermediate adjusting bodies 112 rotate, the two rows of torsion holes 1122 are on the same arc surface, so that two aligned torsion holes 1122 can be conveniently determined to be connected with the rigid connecting piece 120.

In the embodiment of the present utility model, a plurality of torsion holes 1122 are provided, and the torsion holes 1122 are arranged along the adjusting rotation direction of the adjusting arm 1121; in this way, the appropriate torsion connection hole can be quickly determined to be connected with the rigid connection member 120 according to the adjustment angles of the two adjacent intermediate adjustment bodies 112, so as to improve the installation efficiency of the direction holding structure 10 provided by the embodiment of the present utility model.

In some alternative examples, torsion hole 1122 is a shaped hole and the cross-sectional shape of rigid connector 120 matches the shape of the opening of torsion hole 1122.

Specifically, in the embodiment of the present utility model, the cross section of the rigid connection member 120 may specifically refer to a cross section shape of the rigid connection member 120 after the rigid connection member 120 is cross-sectioned along the radial direction of the rigid connection member 120, and the cross section shape of the rigid connection member 120 may specifically be matched with the opening shape of the torsion hole 1122: the cross-sectional shape of the rigid connector 120 is the same as, similar to, or similar to the shape of the opening of the torsion aperture 1122.

In this way, the torsion hole 1122 is configured as a shaped hole, the cross-sectional shape of the rigid connection member 120 matches the opening shape of the torsion hole 1122, and after the rigid connection member 120 is inserted into the torsion hole 1122, the wall of the torsion hole 1122 can abut against the peripheral wall of the rigid connection member 120; in other words, the limiting structure is formed at the corner of the peripheral wall of the rigid connection member 120 and the corner of the wall of the torsion hole 1122, so that the rotation of the rigid connection member 120 in the torsion hole 1122 can be limited, and the stability of the connection between the rigid connection member 120 and the adjustment arm 1121 is improved.

In some specific examples, the inner wall of the torsion aperture 1122 has a stop structure for cooperating with the peripheral wall of the rigid connector 120 to define the degree of freedom of the rigid connector 120 in the circumferential direction of the torsion aperture 1122.

Specifically, the limiting structure may be a protrusion (such as a boss, a bump, or a protruding dot) disposed on an inner wall of the torsion hole 1122, and in actual placement, a corresponding groove may be disposed on a peripheral wall of the rigid connector 120, and the protrusion is inserted into the groove, so as to limit the freedom of the rigid connector 120 along the circumferential direction of the torsion hole 1122.

In other examples, the stop feature may be a depression provided on the inner wall of the torsion aperture 1122 and, when specifically provided, a protrusion may be provided on the peripheral wall of the rigid connector 120. The protruding portion is inserted into the recessed portion.

In other examples, the limiting structure may be a structure in which a part of the inner wall of the torsion hole 1122 along the circumferential direction is formed as a curved surface with a large curvature (for example, an elliptical torsion hole 1122) or an abrupt corner (for example, a square or triangular torsion hole 1122). And corresponding large-curvature cambered surfaces or abrupt corners are arranged on the peripheral wall of the rigid connecting piece 120; so that the radial dimension of the torsion aperture 1122 is a variable dimension, the rigid connector 120 cannot rotate circumferentially within the torsion aperture 1122.

It will be appreciated that in alternative examples of embodiments of the present utility model, the cross-sectional shape of the opening of torsion aperture 1122 may be circular.

The utility model also provides a monitoring equipment supporting device, which comprises: the orientation maintaining structure 10 and pole support of any of the alternative examples of the foregoing embodiments of the utility model; two adjacent mounting bases 111 of the direction holding structure are connected to the pole support.

When the monitoring support rod piece is specifically arranged, the monitoring support rod piece can be arranged at an intersection or transversely arranged above the road surface of the road; the pole support may be disposed on the monitor support bar. In some examples, there may be multiple pole brackets, with each mounting base 111 mounted on one pole bracket.

It can be appreciated that the monitoring device supporting apparatus provided in the embodiment of the present utility model has the same or corresponding technical features and the same or similar technical effects as the direction keeping structure 10 provided in the previous embodiment of the present utility model, and specific reference may be made to the detailed description of the previous embodiment, which is not repeated in the embodiment of the present utility model.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
