Description

Technical Field

[0001] This invention relates to the field of dust control technology in building construction, and in particular to an environmentally friendly dust control device and method for building construction. Background Technology

[0002] To isolate the construction site from the external environment and prevent construction from affecting the surrounding environment, creating a relatively enclosed space, it is often necessary to erect fences to temporarily surround the construction site. During construction, conventional fences are mostly of fixed size and lack adjustment capabilities. They are used for perimeter enclosure of the construction site, effectively achieving site enclosure and noise isolation to some extent. However, as construction intensity increases, a large amount of dust and debris is generated, often requiring taller fences for further containment.

[0003] Patent CN215291834U discloses an adjustable-height construction fence. In this patent, the secondary baffle can be pulled out from the side rails of the main baffle and fixed to the limiting holes on the rails with bolts, thereby achieving fence height adjustment to suit different construction environments. However, because the secondary baffle and the main baffle are fixed with bolts, each height adjustment requires disassembling the bolts and reconnecting them to the limiting holes, resulting in reduced work efficiency.

[0004] In view of the above, how to change the low efficiency of the existing fence height adjustment process has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To overcome the shortcomings mentioned above, this invention aims to provide an environmentally friendly dust control device and method for construction, thereby changing the current situation of low efficiency in the existing technology of adjusting the height of the enclosure.

[0006] In order to achieve the above objectives, the technical solution of the present invention is as follows:

[0007] This invention provides an environmentally friendly dust control device for building construction, comprising:

[0008] Base;

Multiple sets of first blind holes are provided on the front inner side wall of the fixed enclosure. Each set of first blind holes includes multiple first blind holes spaced apart in the vertical direction.

[0010] A movable enclosure that extends through the opening and is slidably connected to the fixed enclosure;

[0011] The locking structure installed on the movable fence includes a locking tongue and a locking assembly. Multiple locking tongues and locking assemblies are correspondingly arranged with multiple sets of first blind holes. The front end of the locking tongue is provided with a ramp surface, which faces forward and upward. The locking tongue is slidably connected to the front inner wall of the fixed fence and can engage with the first blind hole. The locking assembly is used to drive the locking tongue away from the front inner wall of the fixed fence.

[0012] Furthermore, the front sidewall of the movable enclosure is provided with multiple sliding grooves in the vertical direction, and the multiple sliding grooves and multiple sets of the first blind holes are arranged opposite to each other;

[0013] The front inner wall of the fixed enclosure is fixedly connected with a plurality of first sliding blocks. The plurality of first sliding blocks are respectively arranged above the plurality of first blind holes. When the first sliding blocks are slidably connected with the locking tongue, they can drive the locking tongue to move backward until it engages with the locking component.

[0014] Furthermore, the locking assembly includes:

[0015] A first fixing box is fixedly connected to the rear side wall of the movable enclosure, and a first hollow cavity is provided inside the first fixing box;

[0016] A locking ring is slidably disposed in the first hollow cavity along the front-to-back direction, and the front outer side wall and the rear outer side wall of the locking ring are respectively provided with chamfers.

[0017] A movable rod slides through the first fixed box, the locking ring, and the movable enclosure in the front-back direction. The movable rod passes through the side wall of the locking ring twice. A retaining ring is fixedly connected to the middle periphery of the movable rod. The retaining ring is located inside the locking ring. The front end of the movable rod is fixedly connected to the locking tongue.

[0018] A first compression spring is sleeved around the periphery of the movable rod. The front end of the first compression spring is connected to the retaining ring, and the rear end of the first compression spring is connected to the inner wall of the locking ring.

[0019] The first hollow chamber has a second blind hole on its side wall. A protrusion is slidably connected in the second blind hole. The outer walls of the two chamfered corners and the locking rings adjacent to the two chamfered corners are slidably connected to the protrusions. A second compression spring is embedded in the second blind hole. One end of the second compression spring is connected to the protrusion, and the other end of the second compression spring is connected to the inner side wall of the second blind hole.

[0020] When the protrusion is slidably connected to the rear chamfer, the latch is slidably connected to the front inner wall of the fixed enclosure, and the latch can engage with the first blind hole. When the first sliding block is slidably connected to the latch, it drives the latch to move backward so that the protrusion abuts against the front chamfer.

[0021] Furthermore, the movable rod is a prism, and the first hollow cavity and the locking ring include at least one of the following structures:

[0022] In the first case, the cross-sections of the first hollow cavity and the locking ring along the direction perpendicular to the moving rod are matched and the cross-sectional shape is polygonal;

[0023] The second type has a slider on the outer wall of the locking ring and a slide rail on the side wall of the first hollow cavity. The slide rail is slidably connected to the slider, the slide rail is parallel to the movable rod, and the slide rail is not connected to the second blind hole.

[0024] Optionally, the locking component includes:

[0025] A second fixing box is fixedly connected to the rear side wall of the movable enclosure. The second fixing box is provided with a second hollow cavity and has an opening at the front end. A sliding rod is provided on the inner side wall of the second hollow cavity along the front-back direction. A locking tooth is provided in the middle of the sliding rod. A baffle is provided at the rear end of the second fixing box and the baffle is provided with a central hole.

[0026] The baffle is connected to the rear end of the telescopic rod, the front end of the telescopic rod is fixedly connected to the locking tongue, and a third compression spring is provided inside the telescopic rod;

[0027] A sliding plate that slides through the central hole, the second hollow chamber, and the opening in the front-back direction is provided. The front end of the sliding plate is fixedly connected to the locking tongue. The sliding plate is provided with a first through hole in the direction perpendicular to the front-back direction. The two ends of the first through hole are respectively facing the two sliding rods, and the locking teeth are set in the direction of the first through hole. Two locking claws are provided in the first through hole. The rear ends of the two locking claws are hinged to the inner wall of the first through hole through the hinge rod. A fourth compression spring is provided between the two locking claws. The two ends of the fourth compression spring are respectively connected to the two locking claws. The locking claws are sequentially provided with a first arc-shaped surface and a locking slot in the direction of the sliding rod. The locking slot is located at the end of the first arc-shaped surface away from the hinge rod. The first arc-shaped surface is slidably connected to the locking teeth.

[0028] When the first arc-shaped surface slides in connection with the locking teeth, the locking tongue slides in connection with the front inner wall of the fixed enclosure and can engage with the first blind hole. When the first sliding block slides in connection with the locking tongue, it drives the sliding plate to move backward so that the locking slot engages with the locking teeth.

[0029] Optionally, the locking assembly further includes:

[0030] The bottom end of the front inner wall of the fixed enclosure is fixedly connected to a plurality of second sliding blocks. The plurality of second sliding blocks are respectively arranged below the plurality of first blind holes in a corresponding manner. The second sliding blocks protrude from the first sliding blocks in a rearward direction.

[0031] The slide bar is provided with an unlocking tooth, which is located at the rear end of the locking tooth. The unlocking tooth protrudes from the locking tooth in the direction close to the first through hole. The two locking claws have sequentially connected inclined surfaces and second arc-shaped surfaces on their opposite sidewalls. The inclined surface is located at the end of the second arc-shaped surface close to the hinge rod. A magnet is embedded in the inclined surface, and the magnetic poles of the magnets on the two inclined surfaces are opposite.

[0032] The sliding plate is provided with a second through hole in a direction perpendicular to the front and back. The second through hole is a strip-shaped hole in the front and back direction. The second through hole is perpendicular to and connected to the first through hole, and the second through hole is located in front of the first through hole.

[0033] An unlocking rod is fixedly connected inside the second fixing box, and the unlocking rod passes through the second through hole;

[0034] When the second sliding block is slidably connected to the latch, the unlocking tooth drives the two claws to move towards each other and attracts them with two magnets, causing the two inclined surfaces to abut each other, so that the two claws are simultaneously embedded in the first through hole. When the second sliding block stops contacting the latch, the unlocking rod slides sequentially between the two second arc surfaces and between the two inclined surfaces, so that the two claws separate, and the first arc surface is slidably connected to the tooth.

[0035] Optionally, the locking component includes:

[0036] A fixing frame is fixedly connected to the rear side wall of the movable enclosure;

[0037] A first U-shaped frame slides horizontally through the fixed frame and the movable enclosure. The two ends of the first U-shaped frame are slidably connected to the upper and lower ends of the fixed frame, respectively. The middle part of the first U-shaped frame is fixedly connected to the locking tongue. A fifth compression spring is embedded in the notch of the first U-shaped frame. The front end of the fifth compression spring is connected to the first U-shaped frame, and the rear end of the fifth compression spring is connected to the fixed frame. A first U-shaped groove is provided on the upper surface of the upper end of the first U-shaped frame.

[0038] A second U-shaped frame slides vertically through the fixed frame. The two ends of the second U-shaped frame are clamped on both sides of the first U-shaped frame. The two ends of the second U-shaped frame are slidably connected to the fixed frame and rotatably connected to a rotating rod. A sixth compression spring is embedded in the notch of the second U-shaped frame. The lower end of the sixth compression spring is connected to the second U-shaped frame, and the upper end of the sixth compression spring is connected to the fixed frame. A second U-shaped groove is provided on the inner wall of the upper end of the fixed frame. When the second U-shaped groove is opposite to the first U-shaped groove, the rotating rod can be simultaneously embedded in the second U-shaped groove and the first U-shaped groove under the drive of the sixth compression spring. When the second U-shaped frame moves upward relative to the fixed frame, the rotating rod can disengage from the second U-shaped groove and the first U-shaped groove.

[0039] Furthermore, the top of the movable enclosure is detachably connected to the lower end of the connecting rod, and the upper end of the connecting rod is fixedly connected to a clamp. The clamp is used to detachably install a dust suppression component, which is a water mist spraying device that can block dust exceeding the total height of the enclosure by spraying water mist.

[0040] The rear sidewall of the fixed enclosure is hinged to the upper end of the diagonal brace, and the lower end of the diagonal brace is hinged to a support seat.

[0041] Compared with the prior art, the present invention has at least the following advantages:

[0042] During the raising process of the movable fence, the locking tongue selectively engages with the first blind hole, enabling the movable fence to be raised quickly. The locking tongue is locked by the locking component, so that the locking tongue and the front inner wall of the fixed fence are fitted together, enabling the movable fence to be lowered quickly. Compared with the traditional fence bolt fixing method, it has the advantage of fast adjustment speed.

[0043] Another aspect of the present invention provides a dust prevention method based on the above-mentioned environmentally friendly dust prevention equipment for building construction.

[0044] The first step is to fix the base to the installation position;

[0045] The second step is to adjust the height between the movable and fixed fences;

[0046] Third, after use, use the locking assembly to lock the latch, so that the latch is away from the fixed fence, and store the movable fence into the hollow structure of the fixed fence.

[0047] Fourth step: Release the locking assembly from locking the bolt.

[0048] Furthermore, the second step also includes installing dust suppression components above the activity enclosure.

[0049] The dust prevention method described above has the same advantages over existing technologies as the environmentally friendly dust prevention equipment used in construction, and will not be repeated here. Attached Figure Description

[0064] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0066] Reference Figure 1-5 The present invention provides an environmentally friendly dust control device for building construction, including a base 1, a fixed enclosure 2, a movable enclosure 4, and a locking structure.

[0067] The base 1 is used to fix the device to the installation location, such as fixing the base 1 to the ground at the construction site. The fixed enclosure 2 is fixedly installed above the base 1. The fixed enclosure 2 is an open-ended cylindrical structure. Multiple sets of first blind holes 3 are provided on the front inner wall of the fixed enclosure 2. Each set of first blind holes 3 includes multiple first blind holes 3 evenly spaced along the vertical direction. The movable enclosure 4 passes through the open end and is slidably connected to the fixed enclosure 2. A locking structure is provided on the movable enclosure 4. The locking structure includes a locking tongue 5 and a locking assembly, each corresponding to a specific set of first blind holes 3. The front end of the locking tongue 5 has a ramp surface, oriented towards the front and upward vectors and directions. The locking tongue 5 is slidably connected to the front inner wall of the fixed enclosure 2 and can engage with the first blind holes 3. The locking assembly is used to keep the locking tongue 5 away from the front inner wall of the fixed enclosure 2.

[0068] Preferably, the front sidewall of the movable enclosure 4 is provided with multiple sliding grooves, which are arranged vertically, and the multiple sliding grooves and multiple sets of the first blind holes 3 are arranged opposite to each other. Multiple first sliding blocks 7 are fixedly connected to the front inner wall of the fixed enclosure 2. The first sliding blocks 7 are arranged opposite to the sliding groove and are fitted with a gap. The multiple first sliding blocks 7 are respectively arranged above the multiple sets of first blind holes 3. The cross section of the first sliding block 7 in the vertical direction is a right trapezoid. The hypotenuse of the first sliding block 7 is smoothly connected to the front inner wall of the fixed enclosure 2. The lower bottom of the first sliding block 7 is fixedly connected to the front inner wall of the fixed enclosure 2. The length of the upper bottom of the first sliding block 7 is less than the length of the lower bottom of the first sliding block 7. When the first sliding block 7 is slidably connected to the locking tongue 5, the locking tongue 5 slides sequentially to the hypotenuse of the first sliding block 7 and the upper bottom of the first sliding block 7, thereby driving the locking tongue 5 to move backward. During the backward movement of the locking tongue 5, it can engage with the locking component. The locking component can prevent the locking tongue 5 from contacting the front inner wall of the fixed enclosure 2, so that the locking tongue 5 and the front inner wall of the fixed enclosure 2 are fitted with a gap.

[0069] Optionally, in this embodiment, the locking assembly includes a first fixed box 8, a locking ring 9, a movable rod 10, a first compression spring 12, a retaining ring 11, a protrusion 15, and a second compression spring 14.

[0070] The first fixed box 8 is fixedly connected to the rear side wall of the movable enclosure 4, and a first hollow cavity is provided inside the first fixed box 8. A locking ring 9 is slidably disposed within the first hollow cavity in the front-to-back direction. The front and rear outer walls of the locking ring 9 are respectively provided with chamfered angles, which are inclined towards the upper front and upper rear, respectively. A movable rod 10 slides through the first hollow cavity, the locking ring 9, and the movable enclosure 4 in the front-to-back direction. The movable rod 10 passes through the side wall of the locking ring 9 twice. A retaining ring 11 is fixedly connected to the middle periphery of the movable rod 10, and the retaining ring 11 is disposed within the locking ring 9. The front end of the movable rod 10 is fixedly connected to the locking tongue 5. The retaining ring 11 restricts the displacement of the locking tongue 5 in the front-to-back direction. The first compression spring 12 is sleeved around the movable rod 10. The front end of the first compression spring 12 is connected to the retaining ring 11, and the rear end of the first compression spring 12 is connected to the inner wall of the locking ring 9. The first compression spring 12 is used to drive the movable rod 10 and the locking tongue 5 to move toward the first blind hole 3. A second blind hole 13 is provided on the side wall of the first hollow chamber. A protrusion 15 is slidably connected in the second blind hole 13. The outer walls of the two chamfered corners and the locking rings 9 adjacent to the two chamfered corners are slidably connected to the protrusion 15. A second compression spring 14 is embedded in the second blind hole 13. One end of the second compression spring 14 is connected to the protrusion 15, and the other end of the second compression spring 14 is connected to the inner wall of the second blind hole 13. When the protrusion 15 is slidably connected to the rear chamfered corner, the locking tongue 5 is slidably connected to the front inner wall of the fixed enclosure 2 and can engage with the first blind hole 3. At this time, the extension and retraction of the first compression spring 12 causes the locking tongue 5 to be inserted into or disengaged from the first blind hole 3. When the first sliding block 7 is slidably connected to the locking tongue 5, it causes the locking tongue 5 to move backward so that the protrusion 15 abuts against the front chamfered corner.

[0071] The movable rod 10 is a prism, and an end cap is installed at its rear end. The structure of the first hollow chamber and the locking ring 9 includes at least one of the following structures: First, the cross-sections of the first hollow chamber and the locking ring 9 along the direction perpendicular to the movable rod 10 are matched and the cross-sectional shape is polygonal; Second, a slider (not shown in the figure) is provided on the outer wall of the locking ring 9, and a slide rail 16 is provided on the side wall of the first hollow chamber. The slide rail 16 is slidably connected to the slider, parallel to the movable rod 10, and not connected to the second blind hole 13. The above structure ensures that the movable rod 10 and the locking ring 9 do not rotate during movement.

[0072] It should be noted that in this embodiment, two sets of first blind holes 3 are provided, each set consisting of multiple first blind holes 3 arranged at equal intervals along the vertical direction; the front side wall of the movable enclosure 4 is provided with two sliding grooves, and two sets of locking tongues 5 and locking components are provided, with the two sets of locking tongues 5 and locking components symmetrically arranged on the left and right sides of the movable enclosure 4 respectively. The rear side wall of the fixed enclosure 2 is provided with strip-shaped through holes corresponding to the first fixed box 8 to avoid interference between the first fixed box 8 and the fixed enclosure 2 during the up and down movement of the movable enclosure 4. In addition, a handle 44 is installed at the bottom of the rear side wall of the movable enclosure 4, and a strip-shaped through hole corresponding to the handle 44 is provided on the rear side wall of the fixed enclosure 2, making it convenient for workers to control the lifting and lowering process of the movable enclosure 4 by operating the handle 44.

[0073] The top of the movable enclosure 4 is detachably connected to the lower end of the connecting rod 38. The upper end of the connecting rod 38 is fixedly connected to a clamp 39, which is used to install the dust suppression component. The dust suppression device includes a water supply pipe 40 and a nozzle 41. The clamp 39 is used to clamp the water supply pipe 40. The water supply pipe 40 is connected to the nozzle 41. The nozzle 41 is preferably an atomizing nozzle 41, which further improves the dust suppression effect of the present invention by spraying water mist.

[0074] To improve the stability of the present invention, the rear side wall of the fixed enclosure 2 is hinged to the upper end of the diagonal brace 42, and the lower end of the diagonal brace 42 is hinged to the support seat 43.

[0075] Working principle of Example 1:

[0076] First, fix the base 1 to the installation position. Second, adjust the position of the movable rod 10 so that the protrusion 15 slides into the chamfered connection behind the locking ring 9. At this time, the locking tongue 5 slides into the inner front wall of the fixed enclosure 2. The operating handle 44 drives the movable enclosure 4 to rise. During this process, the first compression spring 12 repeatedly extends and retracts, causing the locking tongue 5 to engage or disengage from the first blind hole 3. When the movable enclosure 4 is adjusted to the required height, stop operating the handle 44. Each locking tongue 5 engages with one of the first blind holes 3 in each group, thereby ensuring that the movable enclosure 4 maintains a stable height. After use, use handle 44 to lift the movable barrier 4 further, so that the first sliding block 7 and the locking tongue 5 slide together. The first sliding block 7 will drive the locking tongue 5 to move backward, so that the first compression spring 12 is further compressed. After the first compression spring 12 is further compressed, its elasticity increases further, which will drive the locking ring 9 to move backward. At this time, the second compression spring 14 is compressed, and the protrusion 15 gradually embeds into the second blind hole 13. The locking ring 9 continues to move backward under the elastic force of the first compression spring 12 until the chamfer in front of the locking ring 9 is opposite to the second blind hole 13. The protrusion 15 protrudes out of the second blind hole 13 under the drive of the second compression spring 14. The protrusion 15 further abuts against the chamfer in front of the locking ring 9, so that the locking tongue 5 is away from the front side wall of the fixed barrier 2, and the locking tongue 5 is prevented from getting stuck in the first blind hole 3. At this time, use handle 44 to lower the movable barrier 4 and restore the movable barrier 4 to its initial position. Finally, by pressing the end cap at the rear end of the movable rod 10 forward, the retaining ring 11 on the movable rod 10 drives the locking ring 9 to move forward. Further, the second compression spring 14 is compressed again, and the protrusion 15 is embedded into the second blind hole 13 again. The retaining ring 11 drives the locking ring 9 to continue moving forward. When the chamfered angle behind the locking ring 9 is opposite to the second blind hole 13, the protrusion 15 protrudes out of the second blind hole 13 under the drive of the second compression spring 14. Further, the protrusion 15 slides and connects with the inclined angle behind the locking ring 9. At this time, the locking tongue 5 slides and connects with the front inner wall of the fixed enclosure 2. The locking tongue 5 can be inserted into or disengaged from the first blind hole 3. At this time, the locking tongue 5 is released from locking.

[0077] During the rising process of the movable fence 4, the locking tongue 5 selectively engages with the first blind hole 3, which enables the movable fence 4 to be raised quickly. The locking tongue 5 is locked by the locking component, so that the locking tongue 5 and the front inner wall of the fixed fence 2 are fitted with a gap, which enables the movable fence 4 to be lowered quickly. Compared with the traditional fence bolt fixing method, it has the advantage of fast adjustment speed. Example 2

[0078] Reference Figure 6-9 The difference between this embodiment and Embodiment 1 is that the structure of the locking component is different.

[0079] Specifically, the locking assembly includes a second fixing box 17, a telescopic rod 21, a slide rod 18, a sliding plate 24, and a claw 23.

[0080] The second fixing box 17 is fixedly connected to the rear side wall of the movable enclosure 4. The second fixing box 17 contains a second hollow cavity with an opening at its front end. A sliding rod 18 is installed along the front-rear direction on the inner side wall of the second hollow cavity, and a locking tooth 19 is provided in the middle of the sliding rod 18. A baffle with a central hole is provided at the rear end of the second fixing box 17. The baffle and the locking tongue 5 are connected by a telescopic rod 21. The telescopic rod 21 is a hollow telescopic rod, with its rear end fixedly connected to the baffle and its front end fixedly connected to the locking tongue 5. The telescopic rod 21 can limit the movement of the locking tongue 5. A third compression spring (not shown in the figure) is provided inside the telescopic rod 21, allowing the locking tongue 5 to selectively engage with the first blind hole 3. The sliding plate 24 slides sequentially through the central hole, the second hollow chamber, and the opening in the front-back direction. The front end of the sliding plate 24 is fixedly connected to the locking tongue 5. The sliding plate 24 is provided with a first through hole 22, which is set perpendicular to the front-back direction. Two sliding rods 18 are respectively set at both ends of the first through hole 22, and the locking teeth 19 are set towards the first through hole 22. Two locking claws 23 are provided in the first through hole 22. The rear ends of the two locking claws 23 are hinged to the inner wall of the first through hole 22 through the hinge rod. A fourth compression spring 25 is provided between the two locking claws 23. The two ends of the fourth compression spring 25 are respectively connected to the two locking claws 23. The locking claws 23 are sequentially provided with a first arc-shaped surface 2301 and a locking slot 2302 in the direction of the sliding rod 18. The locking slot 2302 is located at the end of the first arc-shaped surface 2301 away from the hinge rod. The first arc-shaped surface 2301 is slidably connected to the locking teeth 19. During the extension and retraction of the telescopic rod 21, when only the first arc-shaped surface 2301 is slidably connected to the locking tooth 19, the locking tongue 5 is slidably connected to the front inner wall of the fixed enclosure 2 and can engage with the first blind hole 3. When the first sliding block 7 is slidably connected to the locking tongue 5, it drives the sliding plate 24 to move backward. Furthermore, the locking tooth 19 contacts the first arc-shaped surface 2301 and the locking opening 2302 in sequence, thereby engaging with the locking tooth 19 and the locking opening 2302. At this time, the locking tongue 5 is in clearance fit with the front inner wall of the fixed enclosure 2. At this time, the telescopic rod 21 remains stationary and no longer engages.

[0081] In addition, the locking assembly also includes a second sliding block 26. Multiple second sliding blocks 26 are fixedly connected to the bottom end of the front inner wall of the fixed enclosure 2. These second sliding blocks 26 are respectively positioned below multiple sets of first blind holes 3. Each second sliding block 26 protrudes backward from the first sliding block 7. The vertical cross-section of the second sliding block 26 is a right-angled trapezoid. The hypotenuse of the second sliding block 26 is flush with the front inner wall of the fixed enclosure 2, and the lower base of the second sliding block 26 is fixedly connected to the front inner wall of the fixed enclosure 2. The length of the upper base of the second sliding block 26 is less than the length of the lower base, and the height of the second sliding block 26 is greater than the height of the first sliding block 7. The locking tongue 5 slides sequentially to the hypotenuse and upper base of the second sliding block 26, thereby causing the locking tongue 5 to move backward. The slide bar 18 is provided with an unlocking tooth 20, which is located at the rear end of the locking tooth 19. The unlocking tooth 20 protrudes from the locking tooth 19 in the direction close to the first through hole 22. The two locking claws 23 have sequentially connected inclined surfaces 2303 and second arc-shaped surfaces 2304 on their opposite sidewalls. The inclined surface 2303 is located at the end of the second arc-shaped surface 2304 near the hinge rod. A magnet 27 is embedded in the inclined surface 2303. The magnetic poles of the magnets 27 on the two inclined surfaces 2303 are opposite. When the two inclined surfaces 2303 are close together, the two magnets 27 can overcome the spring force of the third compression spring and attract each other, so that the two inclined surfaces 2303 are in close contact. The sliding plate 24 has a second through hole 28, which is a strip-shaped hole. The extension direction of the second through hole 28 is perpendicular to the first through hole 22. The second through hole 28 is connected to the first through hole 22 and is located in front of the first through hole 22. An unlocking rod 29 is fixedly connected inside the second fixed box 17, and the unlocking rod 29 passes through the second through hole 28. When the second sliding block 26 is slidably connected to the locking tongue 5, the unlocking teeth 20 drive the two claws 23 to move towards each other and make the two inclined surfaces 2303 abut against each other through the two magnets 27, so that the two claws 23 are simultaneously embedded in the first through hole 22. When the second sliding block 26 stops contacting the locking tongue 5, the unlocking rod 29 slides sequentially between the two second arc surfaces 2304 and between the two inclined surfaces 2303, so that the two claws 23 are separated, and the telescopic rod 21 is extended and retracted again. At this time, only the first arc surface 2301 is slidably connected to the teeth 19.

[0082] It should be noted that the rear side wall of the fixed fence 2 is provided with a strip-shaped through hole corresponding to the second fixing box 17, so as to avoid interference between the second fixing box 17 and the fixed fence 2 during the up and down movement of the movable fence 4. In addition, a handle 44 is installed at the bottom of the rear side wall of the movable fence 4, and the rear side wall of the fixed fence 2 is provided with a strip-shaped through hole corresponding to the handle 44, so that the staff can control the raising and lowering process of the movable fence 4 by operating the handle 44.

[0083] Working principle of Example 2:

[0084] First, fix the base 1 to the installation position. Second, use the handle 44 to lift the movable barrier 4. During this process, the third compression spring repeatedly extends and retracts, causing the locking tongue 5 to engage or disengage from the first blind hole 3. When the movable barrier 4 is adjusted to the required height, stop operating the handle 44. Each locking tongue 5 engages with one of the first blind holes 3 in each group, thus ensuring that the movable barrier 4 maintains a stable height. During this process, the first arc-shaped surface 2301 is always slidably connected with the locking teeth 19. Because the swing range of the two locking claws 23 is small and the two locking claws 23 are separated by the unlocking rod 29, the two locking claws 23 will not abut against each other due to the attraction between the magnets. After use, the handle 44 is used to drive the movable barrier 4 to continue to rise, so that the first sliding block 7 and the locking tongue 5 are slidably connected. The first sliding block 7 will drive the locking tongue 5 to move backward, so that the third compression spring is further compressed, and the first arc surface 2301 will slide past the locking tooth 19, so that the locking tooth 19 is engaged with the locking slot 2302, thereby limiting the sliding plate 24 in the front and back direction, so that the locking tongue 5 is away from the front side wall of the fixed barrier 2, and the locking tongue 5 is prevented from being engaged with the first blind hole 3. At this time, the handle 44 is used to drive the movable barrier 4 to descend until the locking tongue 5 is slidably connected with the second sliding block 26. During the sliding process of the locking tongue 5 and the second sliding block 26, the locking tongue 5 continues to move backward. Since the unlocking tooth 20 is set to protrude from the locking tooth 19 in the direction close to the first through hole 22, compared with the first During the sliding process of the arc surface 2301 and the locking tooth 19, the distance between the two locking claws 23 is smaller during the relative sliding process between the first arc surface 2301 and the unlocking tooth 20. At this time, the magnetic force between the two magnets 27 is greater than the elastic force of the fourth compression spring 25, which will drive the two locking claws 23 to continue to approach until the two locking claws 23 abut against each other. At this time, the two locking claws 23 will be completely embedded in the first through hole 22. The sliding plate 24 will move forward under the action of the third compression spring. The unlocking rod 29 slides between the two second arc surfaces 2304 and between the two inclined surfaces 2303 in sequence, realizing the separation of the two locking claws 23. The locking tongue 5 is slidably connected to the front inner wall of the fixed enclosure 2 again. The locking tongue 5 can be inserted into or dislodged from the first blind hole 3, further realizing the unlocking process of the locking tongue 5. Example 3

[0085] Reference Figure 10-12 The difference between this embodiment and Embodiment 1 is that the structure of the locking component is different.

[0086] Specifically, the locking assembly includes a fixing frame 30, a first U-shaped frame 31, and a second U-shaped frame 34.

[0087] The fixed frame 30 is fixedly connected to the rear side wall of the movable enclosure 4; the first U-shaped frame 31 slides horizontally through the fixed frame 30 and the movable enclosure 4, with both ends of the first U-shaped frame 31 slidingly connected to the upper and lower ends of the fixed frame 30 respectively, and the middle part of the first U-shaped frame 31 fixedly connected to the locking tongue 5. A fifth compression spring 33 is embedded in the notch of the first U-shaped frame 31, with the front end of the fifth compression spring 33 connected to the first U-shaped frame 31 and the rear end of the fifth compression spring 33 connected to the fixed frame 30. A first U-shaped groove 32 is provided on the upper surface of the upper end of the first U-shaped frame 31; the second U-shaped frame 34 slides vertically through the fixed frame 30, with both ends of the second U-shaped frame 34 clamped to the first U-shaped frame. On both sides of 31, the two ends of the second U-shaped frame 34 are slidably connected to the fixed frame 30 and rotatably connected to the rotating rod 37. A sixth compression spring 36 is embedded in the notch of the second U-shaped frame 34. The lower end of the sixth compression spring 36 is connected to the second U-shaped frame 34, and the upper end of the sixth compression spring 36 is connected to the fixed frame 30. A second U-shaped groove 35 is provided on the inner wall of the upper end of the fixed frame 30. When the second U-shaped groove 35 is opposite to the first U-shaped groove 32, the rotating rod 37 can be simultaneously embedded in the second U-shaped groove 35 and the first U-shaped groove 32 under the drive of the sixth compression spring 36. When the second U-shaped frame 34 moves upward relative to the fixed frame 30, the rotating rod 37 can be dislodged from the second U-shaped groove 35 and the first U-shaped groove 32.

[0088] It should be noted that the rear side wall of the fixed fence 2 is provided with strip-shaped through holes corresponding to the fixed frame 30 to avoid interference between the fixed frame 30 and the fixed fence 2 during the up-and-down movement of the movable fence 4. In addition, a handle 44 is installed at the bottom of the rear side wall of the movable fence 4, and the rear side wall of the fixed fence 2 is provided with strip-shaped through holes corresponding to the handle 44, so that staff can control the raising and lowering process of the movable fence 4 by operating the handle 44.

[0089] Working principle of Example 3:

[0090] First, fix the base 1 to the installation position. Second, adjust the rotating rod 37 to disengage it from the second U-shaped groove 35 and the first U-shaped groove 32. At this time, the locking tongue 5 is slidably connected to the front inner wall of the fixed enclosure 2. Use the handle 44 to drive the movable enclosure 4 to rise. During this process, the fifth compression spring 33 repeatedly extends and retracts, causing the locking tongue 5 to engage or disengage from the first blind hole 3. When the movable enclosure 4 is adjusted to the required height, stop operating the handle 44. Each locking tongue 5 engages with one of the first blind holes 3 in each group, thereby ensuring that the movable enclosure 4 maintains a stable height. After use, use handle 44 to lift the movable barrier 4 further, so that the first sliding block 7 and the locking tongue 5 slide together. The first sliding block 7 will drive the locking tongue 5 to move backward, so that the fifth compression spring 33 is further compressed. When the second U-shaped groove 35 is opposite to the first U-shaped groove 32, the rotating rod 37 can be simultaneously embedded in the second U-shaped groove 35 and the first U-shaped groove 32 under the drive of the sixth compression spring 36, so that the locking tongue 5 is away from the front side wall of the fixed barrier 2, and the locking tongue 5 is prevented from getting stuck in the first blind hole 3. At this time, use handle 44 to lower the movable barrier 4 and restore the movable barrier 4 to the initial position. Finally, when the movable enclosure 4 returns to its initial position, the second U-shaped frame 34 contacts the base 1, causing the sixth compression spring 36 to compress. At the same time, the rotating rod 37 disengages from the second U-shaped groove 35 and the first U-shaped groove 32 again, and the locking tongue 5 slides into the front inner wall of the fixed enclosure 2. The locking tongue 5 can be inserted into or disengaged from the first blind hole 3. At this time, the locking process of the locking tongue 5 is initiated by the unlocking component. Example 4

[0092] First, fix the base 1 to the installation position;

[0093] The second step is to adjust the height between the movable fence 4 and the fixed fence 2.

[0094] Third, after use, use the locking assembly to move the locking tongue 5 away from the fixed enclosure 2, and store the movable enclosure 4 into the hollow structure of the fixed enclosure 2.
