Technical Field

[0001] This utility model relates to the field of table and chair processing and testing technology, specifically a table and chair support leg strength testing device. Background Technology

[0002] Outdoor tables and chairs, as indispensable companions for outdoor activities, are designed and manufactured with the needs of outdoor environments in mind. These tables and chairs not only pursue aesthetics and comfort but also emphasize practicality and durability to adapt to varying outdoor weather conditions and usage scenarios. Outdoor leisure tables and chairs need to withstand the mechanical challenges of various usage scenarios, especially the support legs, which are critical parts bearing the weight and external impacts. Therefore, the strength testing of the support legs has become one of the core standards for evaluating the quality of outdoor tables and chairs. Strength testing not only concerns the stability and safety of the tables and chairs but also tests the manufacturer's craftsmanship and material selection.

[0003] Currently, the testing of table and chair legs mostly involves using a hydraulically driven pressure plate to descend. However, the bottom of the pressure plate is relatively smooth, and the table and chair are not secured during the testing process, making them prone to movement. Furthermore, when the table and chair legs are damaged due to the inability to withstand the pressure, some parts may break off, posing a safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a device for testing the strength of table and chair support legs, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a table and chair support leg strength testing device, comprising a base and a fixing frame, and further comprising:

[0024] 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.

[0025] Please see Figures 1-7 As shown, a table and chair support leg strength testing device includes a base 1 and a fixing frame 2. The fixing frame 2 is bolted to the top of the base 1. The testing device also includes a positioning component 17. Four sets of first hydraulic rods 3 are provided through the surface of the fixing frame 2. The first hydraulic rods 3 are bolted to each other at the through-holes in the surface of the fixing frame 2. The output shaft of the first hydraulic rod 3 is bolted to a frame 4. A connecting frame 5 is bolted between the frames 4. A drive motor 6 is also bolted to the bottom of the connecting frame 5. A transmission column 7 is fixed to the bottom of the connecting frame 5 through a bearing seat, which enables the transmission column 7 to rotate. The output shaft of the drive motor 6 is connected to the transmission column 7 through gear transmission. A rotating column 8 is rotatably connected to the surface of the frame 4, and the two ends of the transmission column 7 are respectively connected to the rotating columns 8 on both sides through bevel gears. The drive column 7 is connected to a rotating plate 9 on both sides of its surface. The rotating plate 9 is connected to a first slot 10 and a second slot 11 on its upper and lower sides, respectively. The inner wall of the first slot 10 is circular and the inner wall of the second slot 11 is square. The bottom of the frame 4 is also connected to a first cover 12. The surface of the first cover 12 is slidably connected to a second cover 13. Both the first cover 12 and the second cover 13 are made of transparent acrylic. Vertical grooves 14 are provided on both sides of the surface of the second cover 13. Connecting blocks 15 are connected to both sides of the surface of the first cover 12. The connecting blocks 15 are slidably connected to the inner wall of the vertical grooves 14. A bottom pad 16 is also attached to the bottom of the connecting block 15. The bottom pad 16 is made of rubber and provides protection when in contact with the bottom of the table and chair.

[0026] The positioning assembly 17 includes a fixing rod 171, a fixing sleeve 172, and a second hydraulic rod 173. One end of the fixing rod 171 is bolted to the connecting frame 5, and the other end of the fixing rod 171 is bolted to the fixing sleeve 172. The fixing sleeve 172 is fitted onto the surface of the second hydraulic rod 173. With the cooperation of the fixing rod 171 and the fixing sleeve 172, the second hydraulic rod 173 is fixed below the connecting frame 5. The output shaft of the second hydraulic rod 173 is bolted with a pin 174. The surface of the frame 4 is provided with a positioning hole 176, and the surface of the rotating plate 9 is provided with a through hole 175. The inner diameter of the through hole 175 is the same as the inner diameter of the positioning hole 176 so that the pin 174 can pass through.

[0027] During operation, the drive motor 6 is first turned on, which drives the transmission column 7 to rotate via gears. Then, the transmission column 7 drives the rotating column 8 to rotate via bevel gears, thereby causing the surface rotating plate 9 to rotate and making the first slot 10 and the second slot 11 rotate in a circular motion, changing their positions. If the bottom of the table and chair legs is round, the first slot 10 needs to be at the bottom; if the bottom of the legs is square, the second slot 11 needs to be at the bottom. Then, the second hydraulic rod 173 is turned on to extend its output shaft, thereby moving the pin 174 so that the pin 174 passes through the positioning hole 176 and the through hole 175, thus positioning the rotating plate 9.

[0028] After selecting and positioning either the first slot 10 or the second slot 11, place the table and chair on top of the base 1, aligning the four legs of the chair with the four slots (e.g., ...). Figure 3 (As shown), then the first hydraulic rod 3 is activated, and its output shaft extends to drive the frame 4 and connecting frame 5 to descend together. Then, the second cover 13 first contacts the bottom surface of the table and chair, while the first cover 12 continues to descend with the frame 4. The connecting block 15 and the vertical groove 14 allow the first cover 12 to connect with the second cover 13, and the first cover 12 can penetrate deep into the interior of the second cover 13. Finally, the first slot 10 or the second slot 11 contacts the legs of the table and chair. Because the legs of the table and chair can enter the first slot... The interior of slot 10 or second slot 11 prevents the table and chair from moving during the inspection process. The pressure of the first hydraulic rod 3 is applied to the legs of the table and chair through the frame 4, rotating column 8, rotating plate 9 and the first slot 10 or second slot 11, thus applying pressure to the legs for inspection. Furthermore, the cooperation of the first cover 12 and the second cover 13 covers the legs of the chair to prevent broken parts from flying and causing injury during the inspection process. Both the first cover 12 and the second cover 13 are made of transparent acrylic material, making it easy to see the condition of the internal legs.
