In order to improve the above problem, an embodiment of the present invention provides a table assembly, which is configured to facilitate the placement of a notebook computer. The workbench assembly is used for being matched with the mounting rack and enabling the workbench assembly to be detachably mounted on the equipment body with the mounting rack. In this embodiment, the mount is fixed to an apparatus body (not shown).
Of course, the table assembly can also be applied to other devices, such as a table of a treatment couch; the items placed on the table assembly are not particularly limited as long as they are within the range of the load of the table assembly.
The table assembly 100 includes a table 10, a connection unit 20, and an adjustment unit 30. The connecting unit 20 is installed at the bottom of the worktable 10 and relatively close to the edge; the bottom of the table 10 is the side facing away from the table 10 for placing the object. The adjusting unit 30 is connected to the connecting unit 20. The table 10 is used to carry an external object. The connection unit 20 is provided to the table 10 and serves to detachably connect the table 10 to the mounting bracket 200. The adjusting unit 30 is used for driving the connecting unit 20 to move relative to the workbench 10, so that the connecting unit 20 can be quickly detached from the mounting rack 200, and the workbench 10 connected to the connecting unit 20 can be detached from the equipment body with the mounting rack 200.
It will be appreciated that in other embodiments, the connection unit 20 may also be provided at other locations, such as at the side of the table 10 or the like, to facilitate connection to the apparatus body; of course, if convenience of installation and processing is not taken into consideration, the connection unit 20 may be installed at other positions of the table 10 as long as the connection of the table 10 to the apparatus body is achieved; the connection unit 20 can also be directly connected to the device body, as long as the device body is correspondingly provided with a connection structure matched with the connection unit 20.
The table 10 includes a table body 11 and a mount 12 fixed to each other. The table body 11 has a substantially square plate-like structure. The mounting seat 12 is formed by bending two sides of a rectangular plate body. The mounting base 12 is bent to form a mounting space (not numbered). The installation space is used to accommodate a part of the connection unit 20.
The bottom of the workbench body 11 and the position relatively close to the edge are partially concave and form a square mounting groove 111. The mounting groove 111 is used to mount the connection unit 20. The installation groove 111 is provided such that a regular installation body is maintained after some components of the connection unit 20 are installed in the table body 11. It is understood that in other embodiments, the structure of the workbench body 11 may be configured accordingly according to actual situations, and is not specifically limited herein; the shape of the mounting groove 111 is also correspondingly configured, for example, as a trapezoidal groove depending on the attachment unit 20 to be mounted, as long as it is possible to realize a regular mounting body which facilitates the mounting of the attachment unit 20 and integrates the table assembly 100.
The connection unit 20 includes a first connection shaft 21 and a second connection shaft 22; and the distance between the first connecting shaft 21 and the second connecting shaft 22 is adjustable by the adjusting unit 30. Specifically, the first connecting shaft 21 is fixed to an inner wall of the mounting groove 111. The second connecting shaft 22 is movably disposed on the mounting seat 12. The position of the second connecting shaft 22 relative to the first connecting shaft 21 changes, enabling the shaft spacing between the second connecting shaft 22 and the first connecting shaft 21 to be changed accordingly. The first connecting shaft 21 is used for rotatably connecting the table body 11 to the mounting bracket 200; the second connecting shaft 22 is used to change the axial distance of the second connecting shaft 22 relative to the first connecting shaft 21.
Correspondingly, the mounting bracket 200 is provided with a first groove 201 and a second groove 202 corresponding to the first connecting shaft 21 and the second connecting shaft 22, and the distance between the notches of the first groove 201 and the second groove 202 is greater than the distance between the first connecting shaft 21 and the second connecting shaft 22. The first groove 201 is used for the first connecting shaft 21 to extend into and rotatably mounting the mounting frame 200 on the workbench body 11; the second slot 202 is used for the second connecting shaft 22 to extend into and fix the workbench assembly 100 to the mounting bracket 200.
Since the distance between the notches of the first groove 201 and the second groove 202 of the mounting bracket 200 is relatively fixed, the first connecting shaft 21 and the second connecting shaft 22 connected to the table body 11 are clamped and fixed to the mounting bracket 200 by the adjustable distance between the shafts under the action of the adjusting unit 30. At this time, the second connecting shaft 22 is configured as a moving shaft. The inner walls of the first groove 201 and the second groove 202 can be clamped between the first connecting shaft 21 and the second connecting shaft 22 through a relatively tightening trend, and the workbench body 11 is fixed on the mounting frame 200; alternatively, the table body 11 may be fixed to the mounting frame 200 by a tendency of relative outward expansion between the first connecting shaft 21 and the second connecting shaft 22.
It should be explained that one or both of the first connecting shaft 21 and the second connecting shaft 22 are configured as a moving shaft so that when one of the first connecting shaft 21 or the second connecting shaft 22 enters the groove, the other one moves into the groove by the driving of the adjusting unit 30. The adjustable distance between the first connecting shaft 21 and the second connecting shaft 22 means that the relative position of the first connecting shaft 21 and the second connecting shaft 22 is adjustable, and the following two conditions are included: 1) the axes of the first connecting shaft 21 and the second connecting shaft 22 are arranged in parallel, and the parallel axes are relatively far away from or close to each other; 2) there is a case where the axes or the extensions of the axes of the first connecting shaft 21 and the second connecting shaft 22 intersect, but the axes of the first connecting shaft 21 and the second connecting shaft 22 have a tendency to relatively approach or relatively separate. As long as the purpose of fixing the table 10 can be achieved by adjusting the distance between the first connecting shaft 21 and the second connecting shaft 22. Correspondingly, the notch distance between the first slot 201 and the second slot 202 also refers to the distance between the centers of the slot bodies, for example, if the first connecting shaft 21 and the second connecting shaft 22 are arranged in parallel, the corresponding notch distance between the first slot 201 and the second slot 202 is the distance corresponding to the center positions of the two slot bodies.
It is understood that in other embodiments, the first connecting shaft 21 may be movably disposed on the workbench 10, and the second connecting shaft 22 may be fixed on the workbench 10, so as to realize the manner of adjusting the distance between the two shafts; or, the first connecting shaft 21 and the second connecting shaft 22 are movably arranged on the workbench 10, so as to realize the adjustable distance between the two; the distance between the first connecting shaft 21 and the second connecting shaft 22 can be adjusted, and the workbench body 11 with the mounting base 12 can be detachably connected to the mounting frame 200 by changing the distance between the first connecting shaft and the second connecting shaft and can be relatively fixed; or the second connecting shaft 22 directly enters the second groove 202 without adjusting the distance between the second connecting shaft and the first connecting shaft 21, as long as the second connecting shaft and the mounting rack 200 can be fixed relatively.
In one embodiment, the first connecting shaft 21 is transversely fixed on the inner wall of the installation groove 111 at two opposite sides, and the axis of the first connecting shaft 21 is parallel to the edge of the worktable 10. The first connecting shaft 21 is correspondingly installed in the first groove 201 of the mounting bracket 200. When the first connecting shaft 21 is mounted in the first groove 201 of the mounting bracket 200 and the second connecting shaft 22 is not mounted in the second groove 202, the first connecting shaft 21 can rotate in the first groove 201 and the table 10 can be rotatably coupled to the mounting bracket 200.
It is understood that, in other embodiments, the first connecting shaft 21 may be obliquely disposed in the mounting groove 111 as long as the first connecting shaft 21 can be rotatably connected to the mounting bracket 200.
In one embodiment, the connection unit 20 further includes a connection plate 23. The first connecting shaft 21 is fixed to the table 10 by a connecting plate 23. The connecting plate 23 is substantially rectangular plate-shaped, and the connecting plate 23 is attached to and fixed to the bottom of the table 10; a avoiding opening (not numbered) is formed at the position of the connecting plate 23 corresponding to the mounting groove 111; the inner walls of the two opposite sides of the avoidance opening are turned towards the direction of the mounting groove 111 to form a connecting part 231; both ends of the first connecting shaft 21 are fixed to the connecting portions 231 provided to face each other. With the arrangement, the first connecting shaft 21 is conveniently fixed on the workbench 10, and the connecting strength between the first connecting shaft 21 and the workbench 10 can be ensured. It is understood that in other embodiments, the connecting plate 23 may be provided with other shapes, such as a semicircular plate-shaped structure, as long as the first connecting shaft 21 can be fixed on the workbench 10; alternatively, the first connecting shaft 21 may be directly fixed to the table 10, and the connecting plate 23 may be omitted accordingly. In the present embodiment, the connection plate 23 may be fixed to the table 10 by a fastener, welding, riveting, or the like.
Preferably, the first connecting shaft 21 is provided integrally with the connecting plate 23. With the arrangement, the processing and the installation of the first connecting shaft 21 are facilitated, and the connecting strength between the first connecting shaft 21 and the connecting plate 23 and between the connecting plate 23 and the workbench 10 are ensured. It is understood that, in other embodiments, the first connecting shaft 21 and the connecting plate 23 may be provided separately, regardless of the connection strength.
Referring to fig. 4, fig. 4 is a schematic structural view of the worktable assembly shown in fig. 2 with some elements omitted.
In one embodiment, the attachment unit 20 further includes a retaining member 25. The mounting seat 12 is fixed to the connecting plate 23. Both ends of the locking member 25 respectively act on the mounting seat 12 and the second connecting shaft 22. The mounting base 12 is used for movably mounting the second connecting shaft 22. The locking member 25 is used to provide a tension force to the second connecting shaft 22.
When the device is installed, the first connecting shaft 21 is aligned and installed in the first groove 201; when the second connecting shaft 22 is mounted in the second groove 202, since the distance between the notches of the first groove 201 and the second groove 202 is smaller than the distance between the first connecting shaft 21 and the second connecting shaft 22, and the position of the notch of the second groove 202 is slightly lower than the position of the second connecting shaft 22, the table 10 needs to be pressed by an external force to align the position of the second connecting shaft 22 with the notch of the second groove 202 and enter the second groove 202. When the second connecting shaft 22 is mounted in the second groove 202 of the mounting bracket 200, the locker 25 tightens the second connecting shaft 22 toward the first connecting shaft 21 to fix the table 10 to the mounting bracket 200 by the tightening force of the second connecting shaft 22 with respect to the first connecting shaft 21.
It is understood that in other embodiments, the locking member 25 can provide the second connecting shaft 22 with an expansion force and make the second connecting shaft 22 have a tendency to move away from the first connecting shaft 21, as long as the workbench 10 can be locked to the mounting frame 200 by changing the distance between the first connecting shaft 21 and the second connecting shaft 22.
Further, in order to facilitate the second connecting shaft 22 to align with the second groove 202 of the mounting bracket 200, the wall surface of the second groove 202 relatively close to the first groove 201 is an outward-expanding inclined slope. During the installation of the second connecting shaft 22, the inclined surface of the second groove 202 moves the second connecting shaft 22 in a direction away from the first connecting shaft 21 until sliding into the second groove 202 during the pressing process. This arrangement facilitates guiding of the second connecting shaft 22 into the second groove 202.
The mounting space of the mounting seat 12 is used for accommodating the second connecting shaft 22. The second connecting shaft 22 is movably connected to two opposite sides of the mounting seat 12. It is understood that in other embodiments, the mounting seat 12 may be integrally provided with the workbench 10, that is, the mounting seat 12 is provided as a part of the workbench 10, as long as the movable mounting of the second connecting shaft 22 is realized.
Specifically, the opposite sides of the mounting seat 12 are provided with corresponding slideways 121. The slide 121 is used for penetrating the second connecting shaft 22, and the second connecting shaft 22 is slidably disposed on the mounting base 12. The opening direction of the slide rail 121 is along a direction perpendicular to the plate surface of the connecting plate 23. The two ends of the second connecting shaft 22 respectively penetrate through the corresponding slide ways 121, and can slide along the opening direction of the slide ways 121 to be close to or far away from the first connecting shaft 21.
It can be understood that, in other embodiments, the second connecting shaft 22 may also be movably connected to the mounting base 12 by a screw rod and a nut, and the adjustment of the axial distance between the second connecting shaft 22 and the first connecting shaft 21 is realized by rotating the screw rod, as long as the adjustment of the axial distance between the first connecting shaft 21 and the second connecting shaft 22 can be realized by changing the position of the second connecting shaft 22; the opening direction of the slide 121 may be inclined with respect to the plate surface of the connecting plate 23 or parallel to the plate surface of the connecting plate 23, as long as the distance between the second connecting shaft 22 and the first connecting shaft 21 can be changed when the second connecting shaft slides along the slide 121.
In one embodiment, the slide 121 allows the axis of motion to have at least two adjustment positions (not numbered) on the table 10; the adjustment positions include a locking position (not numbered) and an unlocking position (not numbered). The locking position is positioned at the position of the slide way 121 relatively close to the first connecting shaft 21; the unlocking position is located at a position where the slide rail 121 is relatively far away from the first connecting shaft. The adjusting unit 30 can move the second connecting shaft 22 from the locking position to the unlocking position, so as to disengage the second connecting shaft 22 from the second groove 202.
In one embodiment, the slide rails 121 on opposite sides of the mounting seat 12 are positioned substantially the same so that the second connecting shaft 22 is disposed parallel to the first connecting shaft 21. This arrangement facilitates the second connecting shaft 22 to be movable in parallel relative to the first connecting shaft 21 and to adjust the shaft interval therebetween.
Preferably, the slideway 121 is a kidney-shaped hole. So set up, the processing of the slide 121 of being convenient for, and the semicircular both ends of slide 121 and second connecting axle 22 looks adaptation.
In one embodiment, the second connecting shaft 22 has snap rings 221 at both ends thereof. The outer diameter of the snap ring 221 is larger than the width of the slide rail 121, and the snap ring 221 is sleeved on the portion of the second connecting shaft 22 extending out of the installation space. Correspondingly, the end of the second connecting shaft 22 is slightly larger than the inner diameter of the snap ring 221, so as to prevent the snap ring 221 from falling out of the end of the second connecting shaft 22. The arrangement of the snap ring 221 can limit the axial position of the second connecting shaft 22 in the slide rail 121; the second connecting shaft 22 is slidably arranged on the mounting seat 12 through the snap ring 221, so that abrasion between the second connecting shaft 22 and the mounting seat 12 can be reduced, and a device can be put into use again only by replacing the snap ring 221, so that the service life of the second connecting shaft 22 is prolonged; further, the snap ring 221 can increase the contact area between the second connecting shaft 22 and the mount 12, thereby enabling the second connecting shaft 22 to be stably provided to the mount 12.
Further, one end of the locking member 25 is fixed to the mounting seat 12, and the other end elastically acts on the second connecting shaft 22 and provides a tension force for locking the second connecting shaft 22 to the locking position. The second connecting shaft 22 is used to lock the work table 10 to the mounting frame 200 with the locking member 25. When the adjusting unit 30 moves the second connecting shaft 22 toward the unlocked position against the tension of the locker 25, the second connecting shaft 22 is released from the second groove, thereby allowing the first connecting shaft 21 to rotate with respect to the mounting bracket 200.
Preferably, as shown in fig. 4, the number of the locker 25 is two. The two locking pieces 25 are elastically applied to both ends of the second connecting shaft 22, respectively, so that the tension of the locking pieces 25 can be stably applied to the second connecting shaft 22.
Further, the locking member 25 is a tension spring. One end of the tension spring is sleeved on the fastening member 242 of the mounting base 12, and the other end is sleeved on the second connecting shaft 22 at a position relatively close to the snap ring 221. So set up for retaining member 25 can act on second connecting axle 22 steadily, and the installation is convenient, the cost is lower.
Referring to fig. 5, fig. 5 is a schematic structural view of the table assembly 100 shown in fig. 4 with some elements omitted.
The adjusting unit 30 is connected to the second connecting shaft 22 and can drive the second connecting shaft 22 to slide in the slide rail 121. The adjusting unit 30 is used for driving the second connecting shaft 22 to move on the workbench 10, so that the adjusting unit can quickly detach the connecting unit 20 from the workbench.
In one embodiment, the adjusting unit 30 is a lever assembly (not numbered). The lever assembly is rotatably mounted on the mounting base and can drive the second connecting shaft 22 to slide in the slide 121, so that the adjusting position of the second connecting shaft in the slide 121 is changed.
It is understood that in other embodiments, the adjusting unit 30 may also be other structures, such as a pull ring structure that directly pulls the second connecting shaft 22, as long as the adjusting position of the second connecting shaft 22 or the first connecting shaft 21 can be changed to disengage the second connecting shaft 22 or the first connecting shaft 21 from the connection with the mounting bracket 200.
Specifically, the lever assembly includes an adjustment wrench 31, an adjustment shaft 32, and an adjustment link 33. The middle position of the adjusting wrench 31 is rotatably connected to the mounting base 12, and one end of the adjusting wrench 31 is connected to the adjusting shaft 32, and the other end extends to the outside of the mounting base 12 and forms a wrench portion 311. The adjusting link 33 has one end connected to an end of the adjusting shaft 32 relatively distant from the adjusting wrench 31 and the other end connected to the second connecting shaft 22. The adjustment wrench 31 is used for applying force to the user and driving the adjustment shaft 32 to rotate. The adjustment shaft 32 serves to transmit the driving force of the adjustment wrench 31 to the adjustment link 33. The adjusting link 33 is used to move the second connecting shaft 22 toward or away from the first connecting shaft 21.
During unlocking, the free end of the adjusting wrench 31 is lifted towards the direction of the workbench 10, and drives one end of the adjusting wrench 31 connected with the adjusting shaft 32 to rotate reversely; the adjusting shaft 32 moves along with the adjusting wrench 31, and drives the second connecting shaft 22 to slide in the slideway 121 through the adjusting connecting rod 33, and moves in a direction far away from the first connecting shaft 21; after the second connecting shaft 22 moves away from the first connecting shaft 21, the second connecting shaft is separated from the second groove 202 of the mounting rack 200; at this time, the table assembly 100 is rotated to draw the first connecting shaft 21 out of the first groove 201. Thereby, the connection unit 20 connected to the table 10 is separated from the mounting frame 200. The installation is the reverse process of the disassembly process, and is not described herein.
In one embodiment, the adjusting link 33 is slidably sleeved on the second connecting shaft 22. In the process that the adjusting link 33 moves along with the adjusting shaft 32, the movement locus of the adjusting link 33 is substantially the same as that of the adjusting shaft 32, and is an arc-shaped movement locus at one end. In order to prevent the axial position of the second connecting shaft 22 from being changed, the adjusting link 33 is sleeved on the second connecting shaft 22 and can slide relative to the second connecting shaft 22. The arc-shaped movement locus of the adjusting link 33 is decomposed into the axial sliding along the second connecting shaft 22 and the axial movement perpendicular to the second connecting shaft 22. The movement perpendicular to the axial direction of the second connecting shaft 22 can drive the second connecting shaft 22 to slide in the slide rail 121, and the sliding of the adjusting link 33 along the axial direction of the second connecting shaft 22 is correspondingly released.
In one embodiment, the wrench portion 311 extends outside the contour of the table 10. With this arrangement, it is convenient for the user to recognize the wrench portion 311 and perform the rotating operation of the adjustment wrench 31 through the wrench portion 311.
One embodiment of the invention provides a workbench, which is detachably connected to an installation frame or an equipment body in a mode of adjusting the distance between shafts of a first connecting shaft and a second connecting shaft under the action of an adjusting unit, so that the workbench can be quickly and conveniently installed or detached from the equipment body provided with the installation frame.
