[0003] Common traditional vehicle blocking facilities such as fixed piles and railings always occupy a certain space in the non-blocking state. They not only affect the overall aesthetics of the site and destroy the harmony of the environment, but also hinder the normal passage of pedestrians and vehicles, reducing the space utilization rate of the site. For this reason, some hidden vehicle blocking devices have appeared in the prior art, which are driven by a driving device to drive the lifting column to rise and fall. When raised, they stand upright on the ground to play a blocking role, and when lowered, they sink into the ground to release the site. However, the hidden vehicle blocking devices in the prior art have the following disadvantages:

[0004] 1. The structure of the driving device that drives the lifting column is complex;

[0005] 2. There is no protection outside the lifting column. When a vehicle hits the raised lifting column, it is usually a head-on collision, which is very easy to damage the lifting column and cause vehicle damage. Summary of the invention

[0006] The invention provides a concealable vehicle blocking device, which is used to solve the technical problems that the lifting column lifting driving device of the existing concealable vehicle blocking device has a complex structure and there is no protection outside the lifting column.

[0024] A box body, with a box opening formed through the top surface;

[0025] A U-shaped plate, which is vertically slidably inserted through the box opening, and the translation frame is horizontally slidably installed inside the U-shaped plate;

[0026] A cover plate, placed on the U-shaped plate, the cover plate is used to cover the box opening and the upper opening of the U-shaped plate, and the through holes are formed on the cover plate;

[0027] A lifting driving assembly, connected between the box body, the U-shaped plate and the cover plate, the lifting driving assembly is used to drive the U-shaped plate to lift relative to the box body and drive the cover plate to lift relative to the U-shaped plate.

[0028] Further, to better implement the present invention, the lifting driving assembly includes:

[0029] A motor, an installation plate is fixedly connected to the outer wall of the U-shaped plate, and the motor is installed on the installation plate;

[0030] A worm, connected to the output shaft of the motor;

[0031] A round shaft, rotatably connected to the outer wall of the U-shaped plate;

[0032] A turbine, installed on the round shaft, and the turbine meshes with the worm;

[0033] A gear is mounted on the circular shaft;

[0034] A first rack and a second rack extending vertically. The bottom end of the first rack is connected to the bottom of the box body, and the top end of the second rack is connected to the bottom surface of the cover plate. The gear meshes with both the first rack and the second rack, and the first rack and the second rack are respectively disposed on both sides of the gear.

The fifth guiding post slidably penetrates through the fifth guiding hole up and down, and a limiting block is installed at the top end of the fifth guiding post.

[0037] The present invention has the following beneficial effects compared with the prior art:

[0038] The retractable vehicle blocking device provided by the present invention drives the translation frame to move leftward in the outer shell through the translation driving component, and then can drive the upper sliding rod and the lower sliding rod to move upward synchronously by means of the upper guiding inclined groove and the lower guiding inclined groove, so that the lifting cylinder and the pushing seat move upward synchronously. At this time, the rubber block is placed in the through hole of the lifting cylinder. When the upper sliding rod slides into the horizontal sliding groove, the lower sliding rod enters the inclined sliding groove. At this moment, the lifting cylinder rises to the topmost position and protrudes upward out of the outer shell, and the rubber block is outside the outer shell. When the translation frame continues to move leftward, because the upper sliding rod translates in the horizontal sliding groove and the lower sliding rod slides in the inclined sliding groove, the inclined sliding groove acts on the lower sliding rod, which will cause the lower sliding rod to continue to lift, and then the pushing seat moves upward relative to the lifting cylinder. In this way, the second inclined surface of the pushing seat will push the first inclined surface of the push block connected to the rubber block, so that the rubber block moves horizontally and extends out of the outer wall of the lifting cylinder. When the translation frame translates rightward in the outer shell, it can drive the pushing seat to move downward first to release the push block and the rubber block. At this time, the rubber block can be pushed into the through hole by an external force (such as manual pushing), and finally the lifting cylinder and the pushing block move downward into the outer shell together.

[0039] Through the above structure, when the lifting cylinder is in a blocking state (that is, when the lifting cylinder rises onto the shell), the rubber block will also extend outward from the lifting cylinder, thereby forming a protection on the outer wall of the lifting cylinder. When a vehicle collides with it, the rubber block can provide a certain buffering effect to protect the lifting cylinder and the vehicle. In addition, the concealable vehicle blocking device drives the translation frame to translate in the shell with the help of the translation drive assembly, so that the lifting cylinder can rise out of the shell or fall into the shell. The structure is ingenious and simple, and it is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope protected by the present invention.

[0064] Embodiment:

[0065] As Figures 1 - 14 shown, the retractable vehicle blocking device provided in this embodiment includes a housing 100, a lifting cylinder 200, a rubber block 300, a pushing seat 400, a translation frame 500 and a translation driving assembly 600, wherein:

[0066] A through hole is provided on the top surface of the housing 100. When installing the device, first dig a pit on the top surface, and then place the housing 100 in the pit so that the top surface of the housing 100 is flush with the bottom surface.

[0067] The lifting cylinder 200 is slidably inserted through the through hole up and down. When the lifting cylinder 200 slides down to the lowest point, the top surface of the lifting cylinder 200 is flush with the top surface of the housing 100. A retaining ring is provided on the outer wall of the bottom end of the lifting cylinder 200. When the lifting cylinder 200 rises to the highest point, most of the section of the lifting cylinder 200 rises above the housing 100, and the retaining ring at the bottom end of the lifting cylinder 200 fits against the inner top wall of the housing 100 for positioning. A through hole is provided on the cylinder wall of the lifting cylinder 200. An upper sliding rod 210 is installed at the bottom of the lifting cylinder 200. Optionally, the upper sliding rod 210 is an L-shaped rod body composed of a vertical rod and a horizontal rod. The top end of the vertical rod is fixedly connected to the bottom end of the lifting cylinder 200, and the horizontal rod is fixedly connected to the bottom end of the vertical rod and extends outward from the lifting cylinder 200. Both the vertical rod and the horizontal rod are round rods, and the vertical rod and the horizontal rod can be integrally formed. Of course, a circular hole can also be provided in the lower part of the vertical rod, and the horizontal rod is rotatably inserted into the circular hole, that is, the horizontal rod can rotate. A lower opening is provided at the center position of the bottom end of the lifting cylinder 200.

[0068] The rubber block 300 is horizontally slidably inserted through the through hole on the cylinder wall of the above-mentioned lifting cylinder 200. A pushing block 310 is connected to the side of the rubber block 300 close to the inside of the lifting cylinder 200. A first inclined surface 311 is provided on the side of the pushing block 310 close to the inside of the lifting cylinder 200. The first inclined surface 311 slopes downward from top to bottom toward the outside of the lifting cylinder 200. Specifically, the above-mentioned pushing block 310 is a structural member made of a hard material.

[0069] The above-mentioned pushing seat 400 is slidably disposed through the above-mentioned lower opening up and down. The outer wall of the pushing seat 400 is provided with a second inclined surface 410, which is inclined from bottom to top toward one side inside the lifting cylinder 200. The second inclined surface 410 is adapted to the above-mentioned first inclined surface 311. In fact, the second inclined surface 410 is in contact with the above-mentioned first inclined surface 311. In this way, when the pushing block moves upward, the second inclined surface 410 will push the first inclined surface 311 upward. Since the rubber block 300 cannot move up and down relative to the lifting cylinder 200, when the first inclined surface 311 is pushed upward by the second inclined surface 410, the pushing block 310 and the rubber block 300 will move horizontally toward the side outside the through hole, so that the rubber block 300 extends upward out of the outer wall of the lifting cylinder 200. A lower sliding rod 420 is installed on the pushing seat 400. Specifically, the lower sliding rod 420 is a round rod extending horizontally. The lower sliding rod 420 can be fixedly connected to the pushing seat 400 or rotatably installed on the pushing seat 400.

[0070] The above-mentioned translation frame 500 is horizontally slidably installed in the above-mentioned housing 100. The translation frame 500 is connected with a translation driving component 600, so as to use the translation driving component 600 to drive the translation frame 500 to translate left and right in the housing 100. The translation frame 500 is provided with upper guiding inclined slots 510 and lower guiding inclined slots 520 that are parallel and equal (specifically, equal in length and coincident in the positive projection on the horizontal plane). The above-mentioned upper sliding rod 210 and lower sliding rod 420 are respectively slidably disposed through the upper guiding inclined slots 510 and lower guiding inclined slots 520. A horizontal sliding slot 530 and an inclined sliding slot 540 are further provided in the translation frame 500. The horizontal sliding slot 530 is connected to the top end of the above-mentioned upper guiding inclined slot 510, and the inclined sliding slot 540 is connected to the top end of the lower guiding horizontal slot. Moreover, the above-mentioned upper guiding inclined slots 510, lower guiding inclined slots 520 and inclined sliding slots 540 are all inclined upward from left to right.

[0071] When the lifting cylinder 200 is at the lowest point, the above-mentioned upper sliding rod 210 is at the bottom end of the upper guiding inclined slot 510, the lower sliding rod 420 is at the bottom end of the lower guiding inclined slot 520, and the translation frame 500 is at the starting point.

[0072] When it is necessary to raise the lifting cylinder 200, the translation driving assembly 600 is used to drive the translation frame 500 to translate leftward. In this way, the upper guiding inclined groove 510, the lower guiding inclined groove 520, the horizontal sliding groove 530 and the inclined sliding groove 540 will all translate leftward synchronously. The upper sliding rod 210 starts to slide along the upper guiding inclined groove 510 from the bottom end of the upper guiding inclined groove 510, so that the upper sliding rod 210 is lifted upward, and then the lifting cylinder 200 rises and extends out of the housing 100 until the upper sliding rod 210 translates to the top end of the upper guiding inclined groove 510. At this time, the lifting cylinder 200 rises to the highest point. At the same time, the lower sliding rod 420 will also start to slide along the lower guiding inclined groove 520 from the bottom end of the lower guiding inclined groove 520, so that the lower sliding rod 420 is lifted upward, and then the pushing seat 400 rises until the lower sliding rod 420 translates to the top end of the lower guiding inclined groove 520. Because the upper guiding inclined groove 510 and the lower guiding inclined groove 520 are parallel and equal, therefore, in the above process, the pushing seat 400 and the lifting cylinder 200 will rise synchronously, that is, there will be no relative movement between the pushing seat 400 and the lifting cylinder 200. Then, the upper sliding rod 210 enters the horizontal sliding groove 530, and the lower sliding rod 420 enters the inclined sliding groove 540. Because the horizontal sliding groove 530 will not cause the upper sliding rod 210 to rise and fall during left-right translation, and the inclined sliding groove 540 will cause the lower sliding rod 420 to rise and fall during left-right translation, therefore, when the translation frame 500 continues to move leftward, the lifting cylinder 200 will no longer continue to rise, while the pushing seat 400 will continue to rise driven by the lower sliding rod 420. During this process, the pushing seat 400 generates relative movement with respect to the lifting cylinder 200. Specifically, the pushing seat 400 rises relative to the lifting cylinder 200. In this way, the pushing seat 400 will push the above-mentioned push block 310 upward. With the cooperation of the first inclined surface 311 and the second inclined surface 410, the push block 310 will be laterally displaced toward the side outside the lifting cylinder 200, and then the rubber block 300 extends out of the outer wall of the lifting cylinder 200. When the lower sliding rod 420 moves to the top end of the inclined sliding groove 540, the upper sliding rod 210 moves to the rightmost end of the horizontal sliding groove 530. At this time, both the pushing seat 400 and the lifting cylinder 200 are at the highest point position, and the translation frame 500 reaches the leftmost end driven by the translation driving assembly 600. At this time, the device is in a blocking state.

[0073] When it is necessary to lower the lifting cylinder 200, the translation driving assembly 600 is used to drive the translation frame 500 to translate rightward. When starting to translate rightward, the upper sliding rod 210 slides in the horizontal sliding groove 530, and the lifting cylinder 200 will not descend. Instead, the lower sliding rod 420 slides downward from the top in the inclined sliding groove 540. Therefore, during this process, the jacking seat 400 will move downward to release the push block 310. At this time, the rubber block 300 can be pushed into the through hole of the lifting cylinder 200 by means of external force (such as manual pushing). When continuing to translate rightward, the upper sliding rod 210 slides downward from the top of the upper guiding inclined groove 510, and the lower sliding rod 420 slides downward from the top of the lower guiding inclined groove 520, thereby driving the lifting cylinder 200 and the jacking seat 400 to descend synchronously downward, and then lowering the lifting cylinder 200 into the housing 100. At this time, the device is in a non-blocking state.

[0074] With the above structure, when the lifting cylinder 200 is in the blocking state (that is, when the lifting cylinder 200 rises onto the housing 100), the rubber block 300 will also extend out of the lifting cylinder 200, thereby forming a protection on the outer wall of the lifting cylinder 200. When the vehicle hits, the rubber block 300 can provide a certain buffering effect to protect the lifting cylinder 200 and the vehicle. Moreover, this retractable vehicle blocking device drives the translation frame 500 to translate within the housing 100 by means of the translation driving assembly 600, so that the lifting cylinder 200 can rise out of the housing 100 or descend into the housing 100. The structure is ingenious and simple, and has strong practicability.

[0075] In order to enable the lifting cylinder 200 and the jacking seat 400 to lift and lower smoothly, in this embodiment, the number of the above upper sliding rods 210 and lower sliding rods 420 is two. The two upper sliding rods 210 are symmetrically arranged on the lifting cylinder 200, and the two lower sliding rods 420 are symmetrically arranged on the jacking seat 400. Correspondingly, the number of the upper guiding inclined grooves 510 and lower guiding inclined grooves 520 arranged on the translation frame 500 is two. The two upper sliding rods 210 are slidably inserted into the two upper guiding inclined grooves 510, and the two lower sliding rods 420 are slidably inserted into the two lower guiding inclined grooves 520.

[0076] Optionally, a convex block 220 is arranged on the inner top wall of the lifting cylinder 200 in this embodiment. A connecting piece 320 is arranged at the top of the push block 310. The connecting piece 320 is movably placed inside the lifting cylinder 200. A transverse spring 330 is installed between the convex block 220 and the connecting piece 320. When the rubber block 300 extends out of the lifting cylinder 200, the transverse spring 330 is in a stretched state. In this way, when the jacking seat 400 moves downward, the push block 310 is released, and the transverse spring 330 will pull the connecting piece 320 to push against the push block 310 and the rubber block 300 to move into the lifting cylinder 200, so that the extended rubber block 300 is reset. In this way, it is not necessary to manually push the rubber block 300 to reset, and the use is more convenient.

[0077] Optionally, a plurality of the above-mentioned through holes are formed in the cylinder wall of the lifting cylinder 200 in this embodiment. The plurality of through holes are evenly distributed along the circumferential direction of the lifting cylinder 200. A rubber block 300 is installed in each through hole. Each rubber block 300 is connected to one of the above-mentioned push blocks 310. A transverse spring 330 is installed between each push block 310 and the lifting cylinder 200. A tapered space with a smaller upper part and a larger lower part is formed between the plurality of push blocks 310. The number of the above-mentioned jacking seats 400 is also multiple. The multiple jacking seats 400 correspond to the multiple push blocks 310 one by one. And the multiple jacking seats 400 are integrally formed on a column 430. A bottom plate 440 is integrally formed at the bottom end of the column 430. The bottom plate 440 is a circular plate. The circular plate and the column 430 are coaxial. The plurality of jacking seats 400 are circumferentially and arrayed around the central axis of the column 430. The lower cross bar is arranged on the outer wall of the bottom plate 440 and extends horizontally out of the bottom plate 440. In this way, when the translation frame 500 moves left and right, it will drive the lower slide bar 420 to drive the bottom plate 440, the column 430 and all the jacking seats 400 to lift, so as to drive all the rubber blocks 300 to synchronously enter and exit the lifting cylinder 200. The plurality of rubber blocks 300 are evenly distributed on the outer wall of the lifting cylinder 200, so that better protection can be provided when in the blocking state. In addition, a vertical spring 240 is installed between the bottom plate 440 and the bottom end of the lifting cylinder 200. The vertical spring 240 is sleeved outside the column 430 and all the above-mentioned jacking seats 400. When the jacking seat 400 and the bottom plate 440 rise relative to the lifting cylinder 200, the vertical spring 240 is compressed. When the bottom plate 440 descends, the vertical spring 240 resets.

[0078] In order to make the lifting of the above-mentioned jacking seat 400 smoother, in this embodiment, a first guiding post 450 is integrally formed on the bottom surface of the bottom plate 440. A rib plate 550 is provided on the translation frame 500. A first guiding hole is formed in the rib plate 550. The first guiding post 450 slidably penetrates through the first guiding hole up and down, so as to guide the lifting of the jacking seat 400 by the cooperation of the first guiding post 450 and the first guiding hole. Optionally, the number of the first guiding posts 450 is two, and the number of the first guiding holes is two. The two first guiding posts 450 are respectively inserted into the two first guiding holes.

An ear 441 is provided on the outer wall of the above-mentioned bottom plate 440, and a second guiding hole is formed in the ear 441. The second guiding column 230 is slidably inserted through the above-mentioned second guiding hole, so as to guide the lifting of the lifting cylinder 200 by the cooperation of the second guiding column 230 and the second guiding hole. Optionally, the number of the above-mentioned ears 441 is two, and each ear 441 is provided with a second guiding hole. The number of the above-mentioned second guiding columns 230 is also two, and the two second guiding columns 230 are respectively inserted through the two second guiding holes. In addition, a connecting block 250 is installed at the bottom ends of the two second guiding columns 230. The connecting block 250 connects the two second guiding columns 230 to make the structure more stable. The connecting block 250 can be bolted and fixed to the second guiding column 230 through bolts.

[0080] Optionally, a T-shaped guiding block 312 is integrally formed on the above-mentioned first inclined surface 311, and a T-shaped sliding groove 411 is formed in the above-mentioned second inclined surface 410.

The connecting plate 620 is connected to the telescopic shaft of the electric cylinder 610, and all the translation frames 500 are connected to the connecting plate 620. In this way, when the electric cylinder 610 extends, the connecting plate 620 drives all the translations to move leftward synchronously, so that all the lifting cylinders 200 are lifted synchronously. When the electric cylinder 610 retracts, the above-mentioned connecting plate 620 drives all the translations to move rightward synchronously, so that all the lifting cylinders 200 are lowered synchronously. The structure of the entire translation driving assembly 600 and the translation frame 500 is simple. Only by driving one electric cylinder 610 to operate, all the lifting cylinders 200 can be driven to lift and lower, and the cost is lower. Of course, the electric cylinder 610 in the above-mentioned translation driving assembly 600 can also be replaced by an electric telescopic rod.

[0082] In order to enable the translation frame 500 to stably translate within the outer shell 100, in this embodiment, a third guiding column 123 is further provided within the outer shell 100. An extension block 560 is provided on each translation frame 500, and a third guiding hole is formed in the extension block 560. The third guiding column 123 is horizontally slidably inserted through the third guiding hole, so as to guide the translation of the translation frame 500 within the outer shell 100 by means of the cooperation between the third guiding column 123 and the third guiding hole. Optionally, the number of the above-mentioned third guiding columns 123 is two, the number of the extension blocks 560 on the translation frame 500 is two, each extension block 560 is provided with a third guiding hole, and the two third guiding columns 123 are respectively inserted through the two third guiding holes.

[0083] An optional implementation manner of this embodiment is as follows: The above-mentioned outer shell 100 includes a box body 110, a U-shaped plate 120, a cover plate 130, and a lifting drive assembly 700, wherein:

[0084] A box opening is formed through the top surface of the box body 110. The above-mentioned U-shaped plate 120 is vertically slidably inserted through the box opening. The translation frame 500 is horizontally slidably installed inside the above-mentioned U-shaped plate 120. The above-mentioned third guiding column 123 is connected inside the U-shaped plate 120. The outer shell 100 of the above-mentioned electric cylinder 610 is connected to the inner wall of the U-shaped plate 120. The cover plate 130 is placed on the U-shaped plate 120, and the cover plate 130 can cover the box opening of the above-mentioned box body 110 and the upper opening of the U-shaped plate 120. The above-mentioned through hole is formed in the cover plate 130.

[0085] The lifting drive assembly 700 is connected among the box body 110, the U-shaped plate 120, and the cover plate 130. The lifting drive assembly 700 is used to drive the U-shaped plate 120 to lift relative to the box body 110 and drive the cover plate 130 to lift relative to the U-shaped plate 120. In this way, when the lifting drive assembly 700 drives the U-shaped plate 120 and the cover plate 130 to descend to the lowest point, the top end of the above-mentioned U-shaped plate 120 is flush with the top surface of the above-mentioned box body 110. The above-mentioned cover plate 130 is lapped on the top end of the U-shaped plate 120 and the top surface of the box body 110, and covers the upper opening of the above-mentioned U-shaped plate 120 and the box opening of the above-mentioned box body 110. When the lifting drive assembly 700 drives the U-shaped plate 120 and the cover plate 130 to rise to the highest point, the above-mentioned U-shaped plate 120 drives the above-mentioned translation drive assembly 600, the above-mentioned translation frame 500, the above-mentioned lifting cylinder 200, and the above-mentioned jacking seat 400 to rise above the box body 110, and makes the cover plate 130 rise above the U-shaped plate 120, thereby exposing the translation drive assembly 600, the above-mentioned translation frame 500, the above-mentioned lifting cylinder 200, and the above-mentioned jacking seat 400, and facilitating the maintenance of the translation drive assembly 600, the above-mentioned translation frame 500, the above-mentioned lifting cylinder 200, and the above-mentioned jacking seat 400.

[0086] Optionally, the lifting drive assembly 700 includes a motor 710, a worm 720, a round shaft 730, a turbine 740, a gear 750, a first rack 760, and a second rack 770, where:

[0087] The motor 710 is installed on a mounting plate 121, and the mounting plate 121 is fixedly connected by welding or heat fusion to the outer wall of the U-shaped plate 120. Of course, it also includes a power supply and a controller. The controller can be a single-chip microcomputer or a chip. The power supply, the electric cylinder 610, and the motor 710 are all electrically connected to the controller, so as to control the operation of the motor 710 and the electric cylinder 610 by using the controller. The axial direction of the worm 720 is vertical. The worm 720 is connected to the rotating shaft of the motor 710 and is located below the mounting plate 121. The motor 710 is installed above the mounting plate 121. The rotating shaft of the motor 710 penetrates downward through the mounting plate 121 and then is connected to the worm 720.

[0088] The round shaft 730 is rotatably connected to the outer wall of the U-shaped plate 120 and is located below the mounting plate 121. The turbine 740 and the gear 750 are both installed on the round shaft 730. The turbine 740 meshes with the worm 720. In this way, when the motor 710 operates, it can drive the worm 720 to rotate, and then drive the turbine 740, the round shaft 730, and the gear 750 to rotate.

[0089] The first rack 760 and the second rack 770 both extend vertically. The bottom end of the first rack 760 is connected to the bottom of the box body 110, and the top end of the first rack 760 extends to the mouth of the box body 110. The top end of the second rack 770 is connected to the bottom surface of the cover plate 130. A protective shell 111 is also communicatively provided on the outer bottom wall of the box body 110. The second rack 770 is slidably inserted through the protective shell 111 and the bottom end of the second rack 770 extends into the protective shell 111. The gear 750 meshes with both the first rack 760 and the second rack 770, and the first rack 760 and the second rack 770 are respectively disposed on both sides of the gear 750. It should be noted that a tooth portion is provided on the lower section of the second rack 770. When the cover plate 130 and the U-shaped plate 120 descend to the lowest point, the gear 750 meshes with the lower part of the first rack 760 and the upper part of the tooth portion. When the motor 710 rotates forward, it drives the gear 750 to rotate in the first direction. Since the first rack 760 is fixed to the bottom of the box body 110, the gear 750 rotating in the first direction rolls on the first rack 760, thereby driving the U-shaped plate 120 and the motor 710 to move upward synchronously through the round shaft 730. The U-shaped plate 120 will push the cover plate 130 upward. At the same time, since the top end of the second rack 770 is fixedly connected to the bottom surface of the cover plate 130, the gear 750 rotating in the first direction will also cause the second rack 770 to move upward, thereby driving the cover plate 130 to move upward relative to the U-shaped plate 120 by using the second rack 770. Thus, both the cover plate 130 and the U-shaped plate 120 move upward relative to the box body 110, and the cover plate 130 also moves upward relative to the U-shaped plate 120. In this way, the motor 710, the turbine 740, the worm 720, and the gear 750 will be exposed, facilitating their maintenance. Conversely, when the motor 710 rotates in reverse, it drives the U-shaped plate 120 and the cover plate 130 to move downward.

[0090] In order to make the up-and-down movement of the cover plate 130 and the U-shaped plate 120 smoother, in this embodiment, a fourth guide post 131 extending vertically is fixedly connected to the bottom surface of the cover plate 130. A fourth guide hole is formed in the top surface of the U-shaped plate 120. The fourth guide post 131 is slidably inserted into the fourth guide hole up and down, so as to guide the lifting of the cover plate 130 relative to the U-shaped plate 120 by the cooperation of the fourth guide post 131 and the fourth guide hole. The number of the fourth guide posts 131 is four. Four fourth guide holes are formed in the top surface of the U-shaped plate 120, and the four fourth guide posts 131 are respectively inserted into the four fourth guide holes. A fifth guide post 112 extending vertically is fixedly connected to the bottom of the box body 110. A boss 122 is provided on the outer wall of the U-shaped plate 120, and a fifth guide hole is formed in the boss 122. The fifth guide post 112 is slidably inserted into the fifth guide hole up and down, so as to guide the lifting of the U-shaped plate 120 relative to the box body 110 by the cooperation of the fifth guide post 112 and the fifth guide hole. Optionally, four bosses 122 are provided on the outer wall of the U-shaped plate 120, and a fifth guide hole is formed in each boss 122. The number of the fifth guide posts 112 is four, and the four fifth guide posts 112 are respectively inserted into the four fifth guide holes.

[0091] In order to prevent the U-shaped plate 120 from sliding upwards out of the fifth guide post 112, a limit block 113 is installed at the top end of the fifth guide post 112. When the boss 122 slides to the top end of the fifth guide post 112, the limit block 113 blocks the boss 122.

[0092] As mentioned above, the above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope recorded in the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
