Description

Technical Field

[0001] This utility model relates to the field of seat processing technology, and in particular to a chair leg universal wheel installation device. Background Technology

[0002] A chair is a type of seating furniture that has a backrest and sometimes armrests.

[0003] Some existing seats have casters installed at the bottom for easy movement. These casters typically snap into pre-drilled holes in the seat legs. However, a typical seat requires five casters, meaning installers must manually attach each caster to its corresponding spot in the seat leg, which is cumbersome and inefficient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a chair leg caster installation device, which solves the technical problem that existing caster installation requires one-to-one snap-fit, resulting in low installation efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A chair leg caster installation device includes an installation plate with an annular placement groove. Several force-bearing blocks are slidably arranged in the placement groove. A first connecting rod is fixed to one end of each force-bearing block. A second connecting rod is slidably arranged at the end of each first connecting rod facing away from the force-bearing block. A storage rod is fixed to the end of each second connecting rod facing away from the first connecting rod. A caster is placed in each storage rod. When the end of the chair leg where the caster is installed faces the storage rod, the chair leg is pressed close to it, so that the caster is embedded in the chair leg.

[0007] Working principle:

[0008] Install the casters on the chair legs as needed, adjust the number of force-bearing blocks in the placement slots, and adjust the positional relationship between adjacent force-bearing blocks. After adjustment, fix the force-bearing blocks. Adjust the positional relationship between the first connecting rod and the second connecting rod. After adjustment, fix the first connecting rod and the second connecting rod. Stack a certain number of casters in the storage rod. When it is necessary to install the casters on the chair legs, bring the chair legs close to the mounting plate so that the casters and the holes in the chair legs are aligned. Press the chair legs to install the casters.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. Five casters can be installed at once, which speeds up the installation process;

[0011] 2. The number of casters can be adjusted according to the required number of casters, making it suitable for installing casters on various types of chair legs. Attached Figure Description

Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example:

[0018] like Figure 1 As shown, a chair leg caster installation device includes an installation plate 11, which is annular. An annular placement groove 10 is formed within the installation plate 11. Several force-bearing blocks 20 are slidably disposed within the placement groove 10. Preferably, in this embodiment, there are five force-bearing blocks 20, with an included angle of 72 degrees between adjacent force-bearing blocks 20. That is, the five force-bearing blocks 20 are evenly arranged within the placement groove 10. A first connecting rod 31 is fixed to one end of each force-bearing block 20. Each first connecting rod 31 has a back... A second connecting rod 19 is provided at one end of the force-bearing block 20 for adjustment and sliding. It can be adjusted according to the number of casters to be installed, and is suitable for the installation of casters for various types of chair legs. A storage rod 18 is fixed at the end of each second connecting rod 19 facing away from the first connecting rod 31. Each storage rod 18 contains a caster. When the end of the chair leg where the caster is installed faces the storage rod 18, press the chair leg close to it so that the caster is embedded in the chair leg. Five casters can be installed at a time, which speeds up the installation efficiency.

[0019] Install the casters on the chair legs as needed, adjust the number of force-bearing blocks 20 in the placement slot 10, and adjust the positional relationship between adjacent force-bearing blocks 20. After adjustment, fix the force-bearing blocks 20. Adjust the positional relationship between the first connecting rod 31 and the second connecting rod 19. After adjustment, fix the first connecting rod 31 and the second connecting rod 19. Stack a certain number of casters in the storage rod 18. When it is necessary to install the casters on the chair legs, bring the chair legs close to the mounting plate 11 so that the casters are aligned with the holes in the chair legs. Press the chair legs to install the casters.

[0020] The mounting plate 11 has a through-hole first mounting groove 22, and a limiting post 21 is fixed in the first mounting groove 22.

[0021] Each load-bearing block 20 is threadedly connected to a first screw 12 with a nut. After the end of the first screw 12 is screwed in, it abuts against the inner wall of the placement groove 10. After the load-bearing block 20 is placed in the corresponding position, the first screw 12 is screwed in to fix the load-bearing block 20.

[0022] One end of the mounting plate 11 is fixedly provided with a first mounting block 25, the first mounting block 25 having a through-hole second mounting groove 23, and a plurality of third connecting rods 26 fixedly provided on the outer periphery of the first mounting block 25. Preferably, such as Figure 2 As shown, in this embodiment, there are four third connecting rods 26. The third connecting rods 26 are opposite to the placement groove 10, and the end of the third connecting rod 26 facing away from the first mounting block 25 is fixed with a second mounting block 24.

[0023] The first connecting rod 31 has an adjustment groove 17 at one end, and the second connecting rod 19 is slidably disposed in the adjustment groove 17. The end of the second connecting rod 19 that is slidably disposed in the first connecting rod 31 is provided with a second screw 14 with a nut. The end of the second screw 14 is threadedly connected with a nut 13. The diameter of the nut 13 is larger than the width of the first connecting rod 31. The nut 13 is screwed in, and the nut 13 and the second screw 14 cooperate to fix the first connecting rod 31 and the second connecting rod 19.

[0024] Each storage rod 18 has a through-hole of a placement cavity 15. A guide cavity 32 is provided on one side of the inner wall of the placement cavity 15. Limiting grooves 16 are provided on both sides of the inner wall of the placement cavity 15. An abutment plate 28 is slidably provided in the limiting groove 16. The placement cavity 15 and the guide cavity 32 cooperate to limit the position of the caster wheel.

[0025] like Figure 3 As shown, a first connecting plate 29 is fixedly provided on both ends of the storage rod 18, and a second connecting plate 30 is fixedly provided between the two first connecting plates 29. A cylinder 27 is fixedly provided at one end of the second connecting plate 30. The telescopic section of the cylinder 27 is fixedly connected to one end of the abutment plate 28. By activating the cylinder 27, the topmost universal wheel part can extend upward into the placement cavity 15, making it convenient for the user to install the universal wheel onto the chair leg.

[0026] Working principle:

[0027] Adjust the positions of the five force-bearing blocks 20 in the placement groove 10. After adjustment, screw in the first screw 12 and adjust the positions of the first connecting rod 31 and the second connecting rod 19. After adjustment, screw in the nut 13 and place the casters in the placement cavity 15 in sequence. Start the cylinder 27. The cylinder 27 drives the abutment plate 28 to move. The abutment plate 28 pushes the casters to move, so that the casters extend upwards out of the placement cavity 15. Align the chair leg holes with the five casters and press the chair legs close to the first mounting block 25 to complete the installation of the casters and chair legs.
