Description

Technical Field

[0001] This utility model relates to the field of prefabricated staircase protection technology, and more specifically, to a foldable protection device. Background Technology

[0002] Precast stairs are widely used in building construction due to their convenience and efficiency. However, during transportation, installation, and use, the surface and edges of precast stairs are easily damaged, affecting their aesthetic appearance.

[0003] In current construction practices, the protection of prefabricated stairs is relatively weak. Generally, waste wooden formwork is used for covering and protection. Over time, as workers step on and off the stairs, the wooden formwork can shift or even fall off, losing its protective function for the prefabricated stairs.

[0004] A search revealed a prefabricated staircase protection device disclosed in Chinese Patent No. CN217000988U. This utility model has a simple structure, is easy to install, and effectively protects prefabricated stairs.

[0005] However, in actual use, the above-mentioned protective devices are fixed with expansion bolts when installed on prefabricated stairs. This process can damage the surface of the prefabricated stairs. Furthermore, the process of removing the protective devices is quite complicated, which affects the efficiency of dismantling the protective devices. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a foldable protective device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A foldable protective device includes multiple kick panels and foot panels arranged from left to right. A positioning mechanism is fixedly connected to the outer side of each foot panel. The positioning mechanism has two fixed plates, with a positioning box rotatably connected to the outer side of each fixed plate. A locking block is slidably connected to the inner side of the positioning box. One locking block has a strap (first strap) fixedly connected to its bottom, and the other locking block has a strap (second strap) fixedly connected to its bottom. A spring is fixedly connected to the inner side of the locking block, and a push block is fixedly connected to its top. The outer side of the push block is slidably connected to the inner side of the locking block. A rod is fixedly connected to the inner side of the push block, with one end of the rod penetrating the locking block and the inner wall of the positioning box and extending to the outer side of the positioning box. Edge pads are slidably connected to the outer sides of both straps (first and second). A ratchet buckle is fixedly connected to one end of strap (first strap), and the other end of the ratchet buckle is fixedly connected to one end of strap (second strap). A back pad is engaged at the top of straps (first and second). A splicing mechanism is provided on the outer side of the kick panels and foot panels.

[0009] By adopting the above technical solution, the back of the prefabricated staircase can be softly fixed using splicable straps one and two, allowing the protective device to be quickly fixed and removed, and reducing damage to the prefabricated staircase during the installation of the protective device.

[0010] As a further description of the above technical solution: the splicing mechanism includes multiple protruding teeth, which are linearly distributed on the outer side of the kick panel and the tread panel. The kick panel and the tread panel are made of rubber. The inner side of the protruding teeth is provided with a slot, and a connecting rod is inserted into the inner side of the slot. Two connecting rods are symmetrically arranged on the outer side of the kick panel. Two nuts are threaded to the outer side of the connecting rod, and the nuts are symmetrically arranged on the outer side of the connecting rod.

[0011] By adopting the above technical solution, multiple protruding teeth on the outer side of the kick panel and tread panel are interlocked, allowing the kick panel and tread panel to be assembled in a timely manner according to the number of steps of the prefabricated staircase. When not in use, multiple kick panels and tread panels can be folded and retracted for relocation and reuse.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a positioning mechanism, compared with the existing technology, multiple tread panels are positioned by using ratchet buckles and straps one and two, so that the protective device composed of the kick plate and tread panels can be stably attached to the precast stairs without the need for fixing with screws or other connectors. This reduces damage to the surface of the precast stairs during the installation of the protective device and facilitates quick installation and removal.

[0014] 2. By setting up a splicing mechanism, compared with the existing technology, the use of the kick plate and tread plate takes into account the protection of the tread and riser of the precast stairs, and also provides sufficient protection for the kicker. At the same time, the protective device composed of the kick plate and tread plate can be repeatedly disassembled and used, which can form a comprehensive protection for the precast stairs and improve the applicability of the protective device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The embodiments disclosed in this application are as follows: Figure 1-6 The foldable protective device shown includes multiple kick panels 1 and foot panels 2, arranged sequentially from left to right. A positioning mechanism is fixedly connected to the outer side of each foot panel 2. The positioning mechanism has two fixed plates 3, with a positioning box 4 rotatably connected to the outer side of each fixed plate 3. A locking block 5 is slidably connected to the inner side of the positioning box 4. One locking block 5 has a strap 6 fixedly connected to its bottom, and the other locking block 5 has a strap 7 fixedly connected to its bottom. A spring 8 is fixedly connected to the inner side of the locking block 5, and a push block 9 is fixedly connected to its top. The outer side of the push block 9 is slidably connected to the inner side of the locking block 5. A rod 10 is fixedly connected to the inner side of the push block 9, with one end of the rod 10 penetrating through the locking block 5 and the inner wall of the positioning box 4 and extending to the positioning box. On the outside of box 4, edge pads 11 are slidably connected to the outside of strap 6 and strap 7. One end of strap 6 is fixedly connected to a ratchet buckle 13, and the other end of ratchet buckle 13 is fixedly connected to one end of strap 7. Back pads 12 are snapped onto the top of straps 6 and 7. A splicing mechanism is provided on the outside of the kick panel 1 and tread panel 2. By using the snapping between two clips 5 and positioning box 4, straps 6, 7 and ratchet buckle 13 can be positioned as a whole on the back pad 12 protective device from the back of the prefabricated staircase. The edge pads 11 and back pads 12 can reduce the friction between straps 6 and 7 and the surface of the prefabricated staircase, and improve the service life of straps 6 and 7.

[0025] Reference Figure 1 , Figure 3 and Figure 4 As shown, the splicing mechanism includes multiple protruding teeth 14, which are linearly distributed on the outer sides of the kick panel 1 and the step panel 2. The kick panel 1 and the step panel 2 are made of rubber. The inner side of the protruding teeth 14 has a slot 15, and a connecting rod 16 is inserted into the inner side of the slot 15. Two connecting rods 16 are symmetrically arranged on the outer side of the kick panel 1. Two nuts 17 are threaded to the outer side of the connecting rod 16. The nuts 17 are symmetrically arranged on the outer side of the connecting rod 16. The kick panel 1 and the step panel 2 are spliced ​​together in an interlocking manner and then connected by the connecting rods 16. This allows multiple kick panels 1 and step panels 2 to be assembled according to usage requirements and to be folded, stored, and moved.

[0026] The working principle of this utility model is as follows: After the prefabricated staircase is installed, according to the number of steps, multiple riser panels 1 and tread panels 2 are first assembled. First, multiple protrusions 14 on one side of a riser panel 1 are interlocked with multiple protrusions 14 on one side of a tread panel 2. Then, a connecting rod 16 is inserted into the corresponding slot 15 inside the interlocking protrusions 14 of the riser panel 1 and tread panel 2, allowing the slot 15 to connect the riser panel 1 and tread panel 2. Next, both ends of the connecting rod 16 are threaded onto nuts 17, allowing the connecting rod 16 to assemble a riser panel 1 and tread panel 2. Then, the riser panel 1 and tread panel 2 are rotated via the connecting rod 16 to an angle corresponding to the inside corner of the staircase, so that the riser panel 1 and tread panel 2 fit against the riser and tread surfaces of the staircase. This assembly process is repeated until multiple riser panels 1 and tread panels 2 can be assembled into a complete unit. The prefabricated staircase has a corresponding number of steps. After assembling to a certain length, a strap 6 and a strap 7 can be wrapped around the back of the prefabricated staircase, so that the two top clips 5 can be inserted into the two positioning boxes 4 on the outer side of the corresponding tread panel 2. Then, the two edge pads 11 on the outer side of strap 6 and strap 7 can be blocked from the contact points between the prefabricated staircase and strap 6 and strap 7. Then, the back pad 12 can be made to contact the back of the prefabricated staircase. Then, by pressing the handle on one side of the ratchet buckle 13, strap 6 and strap 7 can be gradually tightened during the pressing process. Under the rotation of the fixing plate 3 and the positioning box 4, strap 6 and strap 7 can fit against the back of the staircase. The corresponding tread panel 2 is squeezed by strap 6, strap 7, back pad 12 and ratchet buckle 13, so that the protective device is stably connected to the prefabricated staircase.

[0027] After use, the insert rods 10 on both sides of the tread panel 2 can be pressed to enter the inside of the locking block 5. Then the locking block 5 can be moved out from the inside of the positioning box 4. After that, the protective device can be removed from the surface of the precast staircase. Then, multiple kick panels 1 and tread panels 2 can be folded to quickly move to the next precast staircase that needs protection for installation and protection.
