Description

Technical Field

[0001] This utility model relates to the field of furniture processing and manufacturing technology, and in particular to a chair leg pad pressing device. Background Technology

[0002] In modern furniture manufacturing, especially in products such as office chairs and swivel chairs, a five-star base structure with five branches is commonly used as the base support structure. To improve the stability of the chair, protect the floor, provide shock absorption, and increase friction to prevent slipping, a plastic or other elastic material pad is usually installed at each end of the five-star base.

[0003] Currently, the fixing of the foot pad to the end of the five-star base mainly relies on a mechanical snap-fit ​​structure. Specifically, the end of the five-star base has a pre-designed slot with a specific shape, such as a dovetail groove, rectangular groove, or T-shaped groove; correspondingly, a matching insert is integrally formed or fixedly connected to the foot pad body. During installation, the worker needs to manually align the insert on the foot pad with the slot at the end of the five-star base, and then use a hammer or other blunt object to tap the foot pad body, using the impact force to force the insert into the slot. The tight engagement and fixing of the two are achieved by the interference fit or the elastic deformation of the snap-fit ​​structure.

[0004] However, this traditional manual hammering installation method has the following significant drawbacks and technical problems:

[0005] 1. Inefficient and time-consuming: Each five-star leg has five ends, and each chair requires five foot pads. Workers must align and hammer each one individually. In large-scale production, the repetitive hammering consumes a lot of time, severely restricting production efficiency and causing significant physical exertion for workers. 2. Safety hazards: Frequent hammering increases the risk of injury due to operational errors such as slipping, incorrect hammering angle, or excessive force. Splashing debris can also pose a threat to the operator's eyes. 3. Unstable installation quality: Hammering force and angle are difficult to control precisely. Insufficient force may result in the insert not fully engaging, affecting the connection's strength and the foot pad's function; excessive force may cause deformation, cracking, or even damage to the foot pad or the five-star leg ends, increasing the scrap rate. 4. High noise levels: Continuous hammering generates significant noise, worsening the working environment and failing to meet the requirements of modern manufacturing for green and low-noise production environments.

[0006] Therefore, there is an urgent need in the existing technology for a foot pad installation solution that can overcome the above-mentioned shortcomings. Utility Model Content

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] A chair leg pad pressing device, such as Figure 1 and Figure 2 As shown, it includes a base plate 1, a rotary positioning mechanism, an adjusting pressing assembly, a pressing execution mechanism, and a lever drive mechanism.

[0029] The base plate 1 is a rectangular steel plate. The rotation positioning mechanism is located on the upper surface of one end of the base plate 1. The rotation positioning mechanism includes a cylindrical base 2 welded to one end of the base plate 1. A rotating shaft 3 is provided on the base 2. The center seat of the five-star foot 4 is fitted on the rotating shaft 3.

[0030] An adjusting press-fit assembly is located at the other end of the base plate 1, including a first mounting plate 6 and a second mounting plate 19 that can move horizontally along the length of the base plate 1. Two rows of threaded holes 12 are provided on the base plate 1, and through holes for bolts 21 are provided at both ends of the first mounting plate 6 and the second mounting plate 19. Both ends of the first mounting plate 6 and the second mounting plate 19 are fixedly connected to the two rows of threaded holes 12 by bolts 21.

[0031] The press-fitting mechanism includes a support arm 7 vertically fixed to the first mounting plate 6. A vertical ball bearing slide rail 8 is provided on the side wall of the support arm 7. A slider 9 is slidably connected to the slide rail 8. A pressure rod 10 is provided on the slider 9, and a pressure plate 11 is provided at the bottom of the pressure rod 10. The lower surface of the pressure plate 11 is an inclined surface, and the inclination angle of the lower surface of the pressure plate 11 matches the inclination angle of the foot pad 5 during installation. This is because the chair legs of the five-star base 4 have a certain inclination angle, so the foot pad 5 will also have a certain inclination angle during installation. Therefore, the lower surface of the pressure plate 11 can also be set as an inclined surface to match the inclination angle of the foot pad 5, thereby improving the installation effect. The press-fitting mechanism also includes a pressure platform 20 vertically fixed to the second mounting plate 19. The pressure platform 20 is located below the pressure plate 11, and a gasket 24 is provided on the surface of the pressure platform 20.

[0032] The lever drive mechanism includes a connecting lug 13 fixedly connected to the top of the pressure rod 10, with a transmission rod 14 rotatably connected to the connecting lug 13; it also includes an L-shaped pressing handle 17, which includes a transmission part 15 and a handle arm 16. The handle arm 16 is fitted with a protective sleeve 23. One end of the transmission part 15 is rotatably connected to the end of the transmission rod 14 away from the connecting lug 13. A top plate 18 is provided at the top of the support arm 7, and the other end of the transmission part 15 is rotatably connected to the top plate 18. A return spring 22 is also connected between the top plate 18 and the connecting lug 13. The operator can manually rotate the handle arm 16 to drive the transmission part 15 to rotate.

[0033] When using this equipment, after the center seat of the five-star base 4 is placed on the rotating shaft 3, the five-star base 4 is rotated. At this time, the end of the chair leg of the five-star base 4 rotates back between the pressure plate 11 and the pressure platform 20. The pressure platform 20 is used to support the chair leg. The worker manually places the insert of the foot pad 5 in the slot at the end of the chair leg of the five-star base 4. By pressing down the pressure plate 11, the insert is inserted into the slot, and the foot pad 5 is finally installed. By pressing down the handle arm 16 of the pressing handle 17, the handle arm 16 drives the transmission part 15 to rotate. The transmission part 15 drives the transmission rod 14 to rotate, thereby causing the pressure rod 10 to slide down along the slide rail 8. Finally, the pressure plate 11 contacts the foot pad 5 and presses the insert of the foot pad 5 into the slot, thus installing the foot pad 5. During this process, the return spring 22 is stretched. After the foot pad 5 is installed, the return spring 22 retracts, lifting the pressure rod 10 together with the pressure plate 11. The above steps complete the installation of one foot pad 5. To install the next foot pad 5, simply rotate the five-star foot 4 and repeat the above steps.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
