DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments, and all other embodiments obtained by the person skilled in the art without creative labor based on the embodiments in the utility model belong to the protection scope of the utility model.

[0026] Embodiment, please refer to Figures 1-6 The utility model provides a technical scheme:

[0027] A double-layer protective wall structure for a slider bead chain guard includes a slider body 1, mounting holes 2 symmetrically arranged on the top of the slider body 1, allowing personnel to easily fix the device to the top of the slider body 1 using bolts, a first limiting post 10 inserted inside the slider body 1, and a number of first limiting posts 10 equally spaced inside the slider body 1, and first limiting plates 15 fixed to the top of the first limiting posts 10, the number of which is the same as the number of first limiting posts 10. The first limiting plates 15 restrict the position of the first limiting posts 10, preventing them from detaching from the bottom side of the slider body 1. The bottom buffer plate 5 is fixedly connected to the bottom of several sets of first limiting posts 10. A first spring 9 is sleeved on the surface of each first limiting post 10. One end of the first spring 9 is fixed to the inner surface of the slider body 1, and the other end is fixed to the top of the buffer plate 5. When the top side of the slider body 1 is impacted, the slider body 1 moves and compresses the first spring 9, causing the first spring 9 to deform and absorb and buffer the impact force, preventing the impact force from being directly transmitted to the top of the buffer plate 5. A bearing frame 8 is fixed to the bottom of the buffer plate 5. Two sets of bearing frames 8 are symmetrically fixed to the bottom of the buffer plate 5. A slide rail 4 is provided on one side of the bottom of the buffer plate 5. The slide rail 4 is located inside the buffer plate 5 and is slidably connected to the buffer plate 5. A base 3 is fixed to the bottom of rail 4. A support frame 16 is fixed inside the bearing frame 8. Two sets of support frames 16 are symmetrically fixed inside a set of bearing frames 8. A second limiting post 20 is inserted inside the support frame 16. The number of second limiting posts 20 is the same as the number of support frames 16. A mounting frame 11 is fixed to the top of the second limiting post 20. When the mounting frame 11 moves, it will drive the fixed second limiting posts 20 to move. At the same time, the second limiting posts 20 can restrict the position of the mounting frame 11, avoiding or reducing the tilting and shaking of the mounting frame 11 when it moves, thus improving the stability of the mounting frame 11 when it moves. A second limiting plate 19 is fixed to the bottom of the second limiting post 20. The number of mounting frames 11 and second limiting plates 19 is the same as the number of second limiting posts 20. Similarly, the second limiting plate 19 can restrict the position of the second limiting post 20 to prevent the second limiting post 20 from detaching from the support frame 16 from one side. A fixing plate 18 is fixed to the surface of the mounting frame 11, and the surface of the fixing plate 18 has a second limiting hole 21. The number of fixing plates 18 and second limiting holes 21 is the same as the number of mounting frames 11. A second spring 17 is sleeved on the surface of the second limiting post 20. The number of second springs 17 is the same as the number of second limiting posts 20. When the mounting frame 11 moves, it will compress the second springs 17, causing them to deform. Guide wheels 12 are rotatably mounted on the surface of the mounting frame 11 via a rotating shaft. The number of guide wheels 12 is the same as the number of mounting frames 11. A beaded chain 13 is provided between the two sets of guide wheels 12.A bead chain 13 is fitted onto the surfaces of two sets of guide wheels 12. A bead protector 14 is fixed to the surface of the mounting bracket 11. The bead protector 14 is located between the two sets of mounting brackets 11 and is fixedly connected to the surfaces of the two sets of mounting brackets 11. The bead protector 14 is located on one side of the bead chain 13, and one side of the bead chain 13 passes through the inside of the bead protector 14. The bead protector 14 can protect one side of the bead chain 13, preventing the bead chain 13 from shaking or misaligning itself when it comes into contact with the slide rail 4 and rotates, thus improving the stability of the bead chain 13 when rotating. A protective plate 6 is fixed to the surface of the bearing frame 8. Two sets of protective plates 6 are symmetrically fixed to the surface of one set of bearing frames 8. The protective plate 6 reduces or prevents dust and debris from entering the interior of the support frame 8 through both ends. The surface of the protective plate 6 has first limiting holes 7, the number of which is the same as the number of protective plates 6. The first limiting holes 7 are located to one side of the second limiting holes 21. The position of the fixing plate 18 can be fixed by passing a fixing bolt through the first limiting hole 7 and threading the bolt into the second limiting hole 21. This, in turn, fixes the position of the mounting bracket 11 through the fixing plate 18, preventing the guide wheel 12, mounting bracket 11, and bead chain 13 from moving after the equipment is installed.

[0028] The working process of this utility model is as follows: When the device is installed on the top of the slider body 1, if the device collides with the top of the slider body 1, the slider body 1 can move itself and compress the first spring 9 when impacted on one side of the top. This causes the first spring 9 to deform and absorb and buffer the impact force, preventing the impact force from being directly transmitted to the top of the buffer plate 5. This prevents the bearing frame 8, which is fixedly connected to the buffer plate 5, and its internal components such as the bead protector 14 and bead chain 13 from being directly impacted and displaced. It also prevents the bead chain 13 and bead protector 14 from being displaced due to impact and causing squeezing and collision between them and the slide rail 4, thus preventing damage to the surface of the bead protector 14 or bead chain 13. This addresses the issue of the bead protector 14 and bead chain 13, improving their service life and making them relatively convenient to use. Furthermore, when the side of the slider body 1 is impacted, causing slight lateral movement between the slider body 1 and the buffer plate 5, and compressing the bead chain 13, the bead chain 13 pushes the guide wheel 12 to move. This, in turn, causes the guide wheel 12 to move the mounting bracket 11, which in turn pushes one end of the second spring 17 to move and compress the second spring 17. This causes the second spring 17 to deform and absorb and buffer the impact force, preventing the bead chain 13 from making direct lateral hard contact with the slide rail 4. This avoids damage to the bead chain 13 due to hard contact with the slide rail 4, thus improving its service life.

[0029] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
