All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to fig. 4, fig. 1 is a schematic structural diagram of a laser ranging structure according to an embodiment of the present utility model; fig. 2 is a schematic cross-sectional structure of a laser ranging structure according to an embodiment of the present utility model; FIG. 3 is a schematic cross-sectional view of a laser ranging structure according to an embodiment of the present utility model; fig. 4 is an exploded schematic view of a laser ranging structure according to an embodiment of the present utility model.

In a specific embodiment, the present embodiment provides a laser ranging structure, and in particular, the laser ranging structure mainly includes a ranging body 1, a mounting portion 2, and an adjusting mechanism 3.

The ranging body 1, i.e. the core component for performing laser ranging, can be specifically and correspondingly arranged according to the needs. The ranging body 1 generally has a relatively central ranging direction, i.e. the extending direction of the ranging axis. The ranging body 1 itself is not necessarily cylindrical as shown in the figure, and may be square, irregular, or the like. As shown in the figure, the ranging body 1 may specifically include a ranging shell, a ranging main part and a ranging clamping ring, where the head of the ranging body 1 is used for ranging outwards, and during assembly, the tail of the ranging body 1 is inserted into the ranging shell from the head of the ranging shell, and the ranging clamping ring is fixedly connected with the head of the ranging shell, such as a threaded connection or a clamping connection, so as to fix the ranging assembly in the ranging shell. Of course, the structure of the ranging body 1 may be correspondingly set as required.

The adjusting mechanism 3 is arranged between the mounting part 2 and the distance measuring body 1, here not necessarily spatially between the two, but rather acts between the two to transfer force between the two directly or indirectly, i.e. one of the mounting side and the adjusting side of the adjusting mechanism 3 is located at the distance measuring body 1 and the other is located at the mounting part 2. If the adjusting mechanism 3 is threaded through the mounting portion 2 and the inner end abuts against the ranging body 1 to act on the ranging body 1, the threaded portion of the adjusting mechanism 3 threaded through the mounting portion 2 is the mounting side, and the inner end of the adjusting mechanism 3 is the adjusting side. For another example, the mounting side of the adjusting mechanism 3 is connected to the distance measuring body 1, and the adjusting side driving end of the adjusting mechanism 3 is connected to the mounting part 2. When there are two or more adjustment mechanisms 3, the installation direction of some of the adjustment mechanisms 3 may be opposite to the installation direction of the other adjustment mechanisms 3, or the installation direction of each adjustment mechanism 3 may be the same, and may be specifically set as needed. Wherein the adjusting mechanism 3 is a mechanism for adjusting the distance between the adjustment object and the installation object. Specific adjusting mechanisms 3 are mechanisms such as bolts, screws, telescopic cylinders and the like. Specifically, the setting can be made as needed.

When the adjusting mechanism 3 is adjusted, the adjusting mechanism is used for driving the ranging body 1 to move relative to the mounting portion 2, so that the ranging direction of the ranging body 1 is changed, namely, the extending direction of the ranging axis is adjusted until the final requirement is met, and if the final requirement can be met, the calibration requirement can be met.

In some embodiments, the mounting portion 2 may be sleeved on the outer side of the ranging body 1, and the adjusting mechanism 3 is disposed through the mounting portion 2, that is, from the outer side of the mounting portion 2 to the inner side of the mounting portion, where the outer end of the adjusting mechanism 3 is generally exposed on the outer side of the mounting portion 2, so as to facilitate the operation of the adjusting mechanism 3. The inner end of the adjusting mechanism 3 on the inner side of the mounting part 2 acts on the ranging body 1, so that the ranging body 1 can be driven to move relative to the mounting part 2 to change the ranging direction of the ranging body 1 during movable adjustment. Specifically, the adjusting mechanism 3 may be disposed through the mounting portion 2, and the inner end acts on the ranging body 1, the outer end is used for receiving an external force, and when the outer end of the adjusting mechanism 3 receives the external force, the inner end of the adjusting mechanism 3 can drive the ranging body 1 to deflect, so as to change the ranging direction. Wherein the movable form of the adjustment mechanism 3 may be a screw movement, such as a threaded connection; or may be a sliding member that is restrained, such as by a resilient catch.

In some embodiments, for convenience of adjustment, it is preferable that the ranging body 1 and the mounting part 2 are fixedly connected by an elastic locking mechanism 4, so that the position between the ranging body 1 and the mounting part 2 is stable. The elastic locking mechanism 4 has an elastic part engaged in the middle, so that the relative position between the ranging body 1 and the mounting part 2 can be changed by overcoming the elastic force of the elastic part. It should be noted that the elastic locking mechanism 4 should have a sufficient pre-tightening force to avoid random shaking during use, and the pre-tightening force does not cause structural damage to the ranging body 1, especially when the adjusting mechanism 3 is adjusted.

By combining the adjusting mechanism 3, the adjusting mechanism 3 can drive the ranging body 1 to overcome the elastic force of the elastic part on the elastic locking mechanism 4 during adjustment, and the relative mounting part 2 moves to change the ranging direction of the ranging body 1 so as to realize the adjustment requirement. The elastic portion of the elastic locking mechanism 4 may be uniformly disposed around the ranging axis, and the elastic direction of the elastic portion may be a radial direction or an axial direction, and may be specifically disposed correspondingly according to needs. The elastic change in the radial direction is caused by the fact that the ranging body 1 rotates relative to the mounting part 2, so that the local position of the ranging body 1 is inevitably offset in the radial direction; the elastic change in the axial direction is caused by the deflection of the distance measuring body 1, which causes the axial end surface, the shoulder surface, and the like to locally generate the axial deflection.

In this laser rangefinder structure, when using, when the range finding direction does not satisfy the requirement, when needing to readjust, only need rotate adjustment mechanism 3 this moment can, adjustment mechanism 3 drive range finding body 1 on overcoming the elastic force basis of elastic mechanism this moment, and relative installation department 2 activities, and then change the range finding direction of range finding body 1 to make the completion range finding direction adjustment. And because the ranging body 1 is connected with the mounting part 2 through the elastic mechanism, the position can be changed in a better adaptability mode, the damage caused by compression deformation is avoided, the fixed state can be kept, and meanwhile, the adjusting mode is simpler and more convenient. In summary, the laser ranging structure can effectively solve the problem that the current laser ranging mechanism cannot realize calibration and adjustment.

In some embodiments, the adjusting mechanism 3 may be a drawing mechanism or a screw rotating mechanism, and mainly adopts a structure capable of moving to different positions and staying at different positions. If the adjusting screw is used for adjusting, the elastic bayonet lock is used for telescopic adjustment, and other adjusting modes can be used.

When the adjusting mechanism 3 is connected by adopting a screw thread manner, in some embodiments, the adjusting mechanism 3 is rotationally connected with the mounting portion 2 and is relatively fixed along the rotation axis direction, and the inner end of the adjusting mechanism 3 is in screw thread connection with the ranging body 1, so that when the adjusting mechanism rotates relative to the mounting portion 2, the adjusting mechanism 3 cannot follow rotation due to the position relationship between the ranging body 1 and the mounting portion 2, and therefore the adjusting mechanism 3 forms screw movement relative to the ranging body 1, and further the adjustment can be completed.

In some embodiments, it is preferred that the adjusting mechanism 3 includes a knob 31 connected to the mounting portion 2 through a first thread 32, where the knob 31 corresponds to an adjusting manner of an adjusting screw, and an inner end of the knob 31 abuts against the ranging body 1, so as to cause a force applied to an abutting portion of the ranging body 1 when the knob is screwed in, and when the force exceeds an elastic force of the elastic locking mechanism 4, the elastic portion of the elastic locking mechanism 4 is caused to elastically deform, so that the ranging body 1 is pushed to move relative to the mounting portion 2, and because of constraint of connection, the movement herein needs to cause deflection of a ranging direction.

In some embodiments, because knob 31 is threaded, depending on the nature of the threads, if there are no other structural constraints, then infinite adjustment may be achieved. Calibration is facilitated in terms of adjustment accuracy. The knob 31 remains in the current position although the self-locking feature of the threads may be relied upon. However, once the knob 31 is torqued, it will turn somewhat, which will also tend to deflect. In this regard, the present embodiment preferably further includes a thimble 33, in which the mounting portion 2 and the knob 31 can be: one is slidably engaged with the thimble 33 in a direction perpendicular to the axis of the first thread 32, the other is provided with tooth grooves 22 uniformly distributed in a circumferential direction, and wherein the thimble 33 is pushed to the tip end by an elastic means to abut against the tooth grooves 22, so that when the knob 31 is rotated, the thimble 33 abuts against the groove side wall of the tooth groove 22, since the groove side wall is obliquely arranged, under the guidance of the groove side wall, the elastic means generates a component force perpendicular to the groove side wall and a component force parallel to the groove side wall by the acting force of the thimble 33 on the groove side wall, wherein the component force parallel to the groove side wall forces the needle head of the thimble 33 to slide against the groove side wall until being positioned at the groove bottom of the tooth groove 22, at the groove bottom, wherein the component force parallel to the groove side wall is offset by the groove side wall bottom side of the other side wall of the groove. It should be noted that, the top between adjacent tooth slots 22 is generally too narrow to directly contact the top of the thimble 33, which inevitably results in a deflection to one side. When the knob 31 receives torque, the torque must be large enough to overcome the elastic force of the elastic device at the tail of the thimble 33, so that the thimble 33 continues to move along the side wall of the groove toward the groove top. The side walls of the tooth grooves 22 are generally inclined from the tooth tops to the tooth bottoms, and may be inclined planes or inclined curved surfaces, so that when the needle heads of the ejector pins 33 contact with the side walls of the tooth grooves, driving forces for driving the needle heads to slide towards the groove bottoms are generated.

In some embodiments, the engagement between the ejector pin 33 and the slot may be an engagement between the elastic clip protrusion and the clip hole, so as to prevent the knob 31 from being easily rotated, and also provide a certain feedback to the hand, so as to improve the operation comfort.

In some embodiments, as described above, the mounting portion 2 and the knob 31 may be slidably connected to the ejector pin 33, and the knob 31 is provided with the tooth slot 22. Of course, the knob 31 may be slidably connected with the thimble 33, and the tooth slot 22 is provided on the mounting portion 2.

In some embodiments, in order to facilitate the arrangement of the ejector pins 33 and the tooth grooves 22, one of the mounting portion 2 and the knob 31 may be provided with a fitting groove, and the other with a fitting post. Typically, one of the mounting groove and the mounting post is provided with a tooth slot 22 and the other is slidably provided with a thimble 33. For convenient assembly, the thimble 33 is generally connected to the assembly column in a sliding manner, and the tooth slot 22 is arranged on the wall of the assembly slot.

In some embodiments, it is preferable here that the mounting portion 2 is provided with a cylindrical portion 21, wherein an inner cylindrical cavity of the cylindrical portion 21 may serve as the above-mentioned fitting groove. At this time, the axially extending tooth grooves 22 may be uniformly provided on the inner wall of the cylindrical portion 21 in the circumferential direction, and if the tooth grooves 22 are distributed over the entire circumference, the tooth grooves 22 may be distributed only on one inner wall, and the specific distribution range should be set correspondingly according to the required rotation angle range of the knob 31. If the adjustment range of the knob 31 is large, the tooth grooves 22 can be distributed over the whole circumference.

Correspondingly, the inner knob 34 of the knob 31 can be provided with a sliding hole 37, and the thimble 33 and the elastic device are all arranged in the sliding hole 37, and the thimble 33 is in sliding fit with the sliding hole 37 so as to limit the moving direction of the thimble 33. The elastic means preferably abuts against the end of the thimble 33, but may be sleeved on the thimble 33. The elastic means, such as compression elastic means, may in particular be compression springs. The two ends of the elastic device are respectively propped against the hole bottom of the sliding hole 37 and the tail end of the thimble 33, and the needle head of the thimble 33 is in a curved surface and is propped against the tooth slot 22. It should be noted that, in the knob 31, one or more than two ejector pins 33 may be provided, and when a plurality of ejector pins 33 are provided, the plurality of ejector pins 33 are preferably uniformly distributed in the circumferential direction.

At this time, the inner knob 34 of the knob 31 may be passed through the bottom of the cylinder part 21 and engaged with the bottom of the cylinder part 21 by the first screw thread 32 to facilitate the completion of the assembly. At this time of assembly, the elastic means and the thimble 33 may be first fitted to the knob 31, then the knob 31 may be inserted into the cylinder 21 from the outer end of the cylinder 21, and the knob 31 may be rotated so that the knob 31 is connected to the bottom of the cylinder 21 by the first screw 32. For convenience of abutting against the knob 31, the corresponding side surface of the ranging body 1 may be formed with a cut surface to be matched with the abutting end of the knob 31.

In some embodiments, the knob 31 may further include an outer knob 35 covering the outer side of the cylinder 21, where the outer knob 35 and the inner knob 34 are fixedly connected by a screw 36, and in actual operation, a torque needs to be applied by the outer knob 35 to drive the whole knob 31 to rotate. Wherein the outer knob 35 may be provided with anti-slip threads. Wherein the outer knob 35 is fixedly connected with the inner knob 34 by means of screws 36, the outer knob 35 can be removed if necessary, so that the entire knob 31 cannot be operated any more by external force.

In some embodiments, only one adjustment mechanism 3 may be provided to adjust in only a single direction. But the adjustment of the ranging direction generally requires adjustment from two dimensions.

Based on this, a plurality of adjustment mechanisms 3 are preferably provided here, which are arranged around the distance measuring body 1, and the adjustment directions are arranged crosswise, so that the adjustment of the different directions and thus the adjustment of the different dimensions is made. The distance measuring direction is generally the Z-axis direction, and only one adjusting mechanism 3 is required to be provided in each of the X-axis direction and the Y-axis direction. The X axis and the Y axis are perpendicular to the Z axis, and the included angle between the X axis and the Y axis is an acute angle, a right angle or an obtuse angle, and can not be a flat angle or a zero angle.

In some embodiments, one side of the ranging body 1 may be made to abut against two adjustment mechanisms 3 disposed crosswise, so that the two adjustment mechanisms 3 are adjusted from different directions, respectively. And in the opposite direction to the pushing direction of the adjusting mechanism 3, can be pushed by means of the elastic force of the above-mentioned elastic locking mechanism 4.

But such pushing may be unreliable. Further, the other side may be abutted against the mounting portion 2 by an elastic abutment 5. Wherein the resilient abutment 5 may be a resilient tab.

In some embodiments, the adjusting directions of the two crossed adjusting mechanisms 3 may be perpendicular, for example, the included angle is a right angle, and may be an acute angle, a right angle or an obtuse angle. Of course, the two adjusting mechanisms which are vertically arranged in the two adjusting directions can be arranged on the same side of the ranging body 1.

In some embodiments, wherein the resilient locking mechanism 4 may be a resilient abutment 5 as described above. However, in this fixing method, it is difficult to control the position of the ranging body 1 with respect to the mounting portion 2. In practical applications, it should be ensured primarily that the position between the ranging body 1 and the mounting part 2 is stable. In view of this, it is preferred here that the elastic locking mechanism 4 mainly comprises a locking member 41 and an elastic member 42, and that the locking member 41 is connected to the distance measuring body 1 by means of a second thread 43, wherein the axis of the second thread 43 extends in the distance measuring direction of the distance measuring body 1, which is not required to be completely identical, but only in which direction an extension is required. Generally, the axis of the second thread 43 coincides with the ranging direction of the ranging body 1 and is coaxially disposed.

The elastic member 42 is elastically deformable along the ranging direction of the ranging body 1, and two sides of the elastic direction are respectively abutted against the mounting portion 2 and the locking member 41. The distance measuring body 1 is pushed to be abutted and fixed on the mounting part 2 by the locking of the locking piece 41, and the distance measuring body is limited by the elastic piece 42, so that a certain elastic movable space is provided, and the adjusting mechanism 3 is adjusted.

In some embodiments, the elastic member 42 provided in this embodiment is preferably a wave-shaped elastic member 42 having a ring-shaped structure and wave-shaped in the circumferential direction.

In some embodiments, the mounting part 2 may comprise a cylinder 23, and the ranging body 1 is inserted into the cylinder cavity from one end of the cylinder 23 and is connected with the locking piece 41 at the other end of the cylinder 23; the side of the cylinder 23 is provided with an adjusting mechanism 3.

Specifically, as shown in the drawings, the tail of the ranging body 1 is inserted into the barrel cavity from the head of the barrel 23, and the head of the ranging body 1 abuts against the head of the barrel 23 to prevent further rearward movement. The locking member 41 is inserted into the barrel cavity from the tail of the barrel cavity and is connected with the tail of the ranging body 1 through the second thread 43, a shoulder part is arranged in the barrel 23, the elastic member 42 is positioned between the shoulder part and the pushing part of the locking member 41 and is compressed between the shoulder part and the pushing part, namely, the locking member 41 is rotated relative to the ranging body 1, the locking member 41 moves towards the head direction until the elastic member 42 is pushed to one side to be abutted against the shoulder part, and the locking member 41 is continuously rotated, at the moment, the shoulder part and the pushing part are close to each other until the elastic member 42 is compressed.

In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
