Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of positioning and installation of track expansion parts, in particular to a limit structure for track expansion parts. Background Art
[0002] A track expansion part is an expansion device used in cooperation with a track. The track is installed on the ceiling, and the expansion device is installed at the bottom of the track and can slide along the track. The expansion device slides along the track until it reaches the designated installation position, and then the expansion device is fixed to the track. Usually, in order to determine the installation position of the expansion device, position marks need to be set on the track for positioning the expansion device, so that the expansion device can be slid to the designated position for fixation. However, setting the position marks only roughly marks the installation position of the expansion device, and during the specific installation, the position of the expansion device still needs to be aligned and positioned. In particular, if the force applied to pull the expansion device is too large, even if the pulling force is withdrawn, the expansion device will continue to slide due to inertia and thus exceed the position mark; if the force applied to pull the expansion device is too small and the pulling force is withdrawn in advance, the expansion device may stop before sliding to the position mark. In both cases, the expansion device needs to be accurately positioned again, and the positioning operation is troublesome and the work efficiency is low.
[0003] Therefore, there is an urgent need to propose a limit structure for track expansion parts to solve the above problems. Summary of the Utility Model

[0030] The rail expansion part limiting structure provided by this embodiment can achieve the precise positioning and installation of the expansion component, and the positioning operation is simple and the work efficiency is high.
[0031] Specifically, as shown in Figure 1 , Figure 2 and Figure 3 , this rail expansion part limiting structure includes a rail 100, an expansion component 200 and a limiting component 300. The rail 100 is horizontally arranged and extends along a first direction, and a limiting point 101 is provided on the rail 100. The expansion component 200 includes an expansion box 210, and the expansion box 210 is slidably connected to the bottom of the rail 100 and can slide along the first direction. The limiting component 300 is located on the expansion box 210. When the expansion box 210 slides and drives the limiting component 300 to move to the limiting point 101, the limiting component 300 can be clamped at the limiting point 101 to limit the displacement of the expansion box 210.
[0032] Based on the above design, the expansion component 200 includes an expansion box 210. The expansion box 210 is slidably connected to the bottom of the rail 100 and can slide along the first direction, realizing the function of mounting the movement of the expansion component 200 on the rail 100. A limiting point 101 is provided on the rail 100, and the limiting component 300 is located on the expansion box 210. When the expansion box 210 slides and drives the limiting component 300 to move to the limiting point 101, the limiting component 300 can be clamped at the limiting point 101 to limit the displacement of the expansion box 210, precisely positioning the moving position of the expansion component 200 on the rail 100, realizing the positioning and installation of the expansion component 200, and the positioning operation is simple and the work efficiency is high.
[0033] Furthermore, connecting holes are provided on the track 100 at intervals along the first direction, and connecting bolts pass through the connecting holes to fix the track 100. Usually, the track 100 is fixed to the ceiling (not shown in the figure), and the connecting bolts can detachably fix the track 100, facilitating the disassembly of the track 100.
[0034] There are various ways to slidably connect the track 100 and the expansion box 210. In some embodiments, two sliding grooves 102 extending along the first direction are provided at the bottom of the track 100. The two sliding grooves 102 are arranged at intervals along the second direction. The expansion assembly 200 further includes two groups of sliders 220. The two groups of sliders 220 are arranged on the top of the expansion box 210, and the two groups of sliders 220 are respectively slidably arranged in the corresponding sliding grooves 102. The first direction is perpendicular to the second direction. The sliding grooves 102 are provided at the bottom of the track 100. Taking advantage of the feature that the track 100 extends along the first direction, the processing is simple.
[0035] The first direction is the length direction of the track 100, i.e., the L direction in the figure; the second direction is the width direction of the track 100, i.e., the B direction in the figure.
[0036] It should be noted that the number of the sliding grooves 102 can be four, five, six, etc., and the present embodiment does not make specific limitations on this.
[0037] Considering comprehensively from the aspects of cost, connection strength and balance, setting two is the optimal choice.
[0038] Usually, the expansion box 210 is magnetically attracted to the track 100, increasing the connection strength between the track 100 and the expansion device, and the magnetic attraction setting is simple.
[0039] In a specific embodiment, a first magnet is provided between the two sliding grooves 102 at the bottom of the track 100, and a second magnet is provided on the top of the expansion box 210. The first magnet and the second magnet are of opposite genders.
[0040] In another specific implementation, a third magnet is provided between the two sliding grooves 102 at the bottom of the track 100, and a first iron bar is provided on the top of the expansion box 210.
[0041] In yet another specific embodiment, a second iron bar is provided between the two sliding grooves 102 at the bottom of the track 100, and a fourth magnet is provided on the top of the expansion box 210.
[0042] Continue as Figure 2 and Figure 3 shown, in order to make the structure of the limiting structure of the track expansion part compact, the limiting component 300 is connected to the slider 220 and is located in the sliding groove 102, and the limiting point 101 is located in the sliding groove 102.
[0043] In this embodiment, the limit point 101 includes a limit hole in the vertical direction. The limit hole is located at the bottom of the chute 102. The limit assembly 300 includes an elastic limit member 310. One end of the elastic limit member 310 passes through the slider 220 in the vertical direction, and the other end abuts against the bottom of the chute 102. And when the elastic limit member 310 is squeezed and the slider 220 moves so that the elastic limit member 310 is aligned with the limit hole, the elastic limit member 310 returns to its original position and is clamped in the limit hole. Specifically, the slider 220 slides in the chute 102, driving the elastic limit member 310 to move. When the expansion box 210 has not reached the installation position, the elastic limit member 310 has not reached the limit hole, and the elastic limit member 310 will be pressed into the interior of the slider 220 and abut against the bottom of the chute 102; when the expansion box 210 reaches the installation position, the elastic limit member 310 reaches the limit hole and is aligned with the limit hole, and the elastic limit member 310 rebounds and inserts into the limit hole. The limit hole is simple to set, and the elastic limit member 310 is simple to install, making the positioning operation of the expansion box 210 simple.
[0044] Further, in order to limit the elastic limit member 310 and facilitate the installation of the elastic limit member 310, the limit assembly 300 further includes an embedding cylinder 320. The embedding cylinder 320 is embedded in the slider 220 in the vertical direction. One end of the elastic limit member 310 abuts against the bottom of the embedding cylinder 320, and the other end of the elastic limit member 310 abuts against the bottom of the chute 102.
[0045] Furthermore, in order to facilitate the installation of the embedding cylinder 320, a peripheral edge is provided on the circumferential edge of the embedding cylinder 320. The peripheral edge is clamped on the top of the slider 220, and the connection strength between the embedding cylinder 320 and the slider 220 is also increased.
[0046] In this embodiment, the limit assembly 300 includes a spring 311 and a chuck 312. One end of the spring 311 abuts against the bottom of the embedding cylinder 320, and the other end is connected to the chuck 312. The chuck 312 abuts against the bottom of the chute 102. The spring 311 has a low cost, the chuck 312 has a high strength, and the clamping effect is good.
[0047] After positioning the position of the expansion box 210, in order to increase the connection strength between the expansion box 210 and the track 100 and increase the load-bearing capacity of the expansion box, the track expansion member limit structure further includes a load-bearing bolt 400. The load-bearing bolt 400 passes through and connects the expansion box 210 and the track 100. In this embodiment, the load-bearing bolt 400 is located between two chutes 102.
[0048] It should be noted that a conductive member extending in the first direction is provided on the track 100, and a power-taking member is provided on the expansion box 210 to realize the power-taking function of the expansion assembly 200. A plurality of jacks are provided on the outside of the expansion box 210, and the jacks are electrically connected to the power-taking member. In this embodiment, the jacks are located on both sides of the expansion box 210 along the second direction.
[0049] In this embodiment, the conductive member is a plurality of conductive bars disposed between two chutes 102.
[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
