Description

Technical Field

[0001] This utility model relates to the field of air pump testing technology, specifically an air pump strength testing device. Background Technology

[0002] Air pumps, as the core component of manual or semi-automatic inflation devices, are typically made of high-strength metals (such as aluminum alloys and stainless steel) or engineering plastics. Structurally, they include a rod, piston, seals, and connecting parts. Their working principle is based on piston-type gas compression. Manual or mechanical drive causes the rod to reciprocate, driving the piston in a linear motion within the cylinder, compressing external air and injecting it into tires, balls, air cushions, and other objects requiring inflation. Air pumps are widely used in sports equipment, automotive repair, and outdoor gear due to their portability and ease of operation. Furthermore, with technological advancements, some air pumps integrate pressure detection and rapid inflation functions, further enhancing ease of use and inflation efficiency.

[0003] In existing technologies, air pumps undergo multiple production steps, including strength testing. The middle section of the pump shaft is prone to bending and deformation during inflation. When the pump is pushed forcefully, the middle section experiences a significant bending moment. Applying pressure to the middle section during testing verifies the bending strength of the shaft material and checks for excessive bending or even breakage.

[0004] However, after the testing is completed, the air pump needs to be removed from the testing table. The traditional method is to remove the air pump by using a mechanical gripper. If the gripping force of the mechanical gripper is not properly controlled, it can easily cause scratches, dents and other damage to the surface of the air pump, affecting the appearance quality and performance of the product. This is especially true for air pumps with high surface treatment requirements or soft materials. Therefore, we propose an air pump strength testing device. Utility Model Content

A receiving rack 110 is provided. One end of a sliding plate 115 is fixedly connected to one side of the receiving rack 110. A telescopic rod 19 is provided on one side of the receiving rack 110. The side of the receiving rack 110 is fixedly connected to the outer side of the bottom end of the telescopic rod 19. A bracket 18 is provided at the top of the telescopic rod 19. The top of the telescopic rod 19 is fixedly connected to the bracket 18. A toothed plate 17 is provided at the top of the bracket 18. The top of the bracket 18 is fixedly connected to the bottom side of the toothed plate 17. A gear 16 is provided on the top side of the toothed plate 17. The top side of the toothed plate 17 is rotatably meshed with the outer side of the gear 16. One end of the side of the gear 16 is fixedly connected to the sliding plate 115. The inner wall of the fixed frame 13 is rotatably connected through it. A positioning seat 14 is provided on the inner side of the fixed frame 13. One end of the positioning seat 14 is rotatably connected to the inner side of the fixed frame 13. One side of the positioning seat 14 is fixedly connected to one side of the gear 16. A slider 112 is provided on one side of the bracket 18. One side of the bracket 18 is fixedly connected to one end of the slider 112. The outer side of the slider 112 is slidably connected to the inner wall of one side of the receiving rack 110. A folding plate 113 is provided on the top side of the side plate 12. The top side of the side plate 12 is fixedly connected to the bottom end of the folding plate 113. A detection device is provided on the inner wall of one end of the folding plate 113. The inner wall of one end of the folding plate 113 of the equipment body 114 is fixedly connected to the outer side of the testing equipment body 114. The inner side of the positioning seat 14 is provided with a textured plate 15, and the inner side of the positioning seat 14 is fixedly connected to one side of the textured plate 15. The inner wall of one side of the fixing frame 13 is provided with a cylinder rod 116, and the inner wall of one side of the fixing frame 13 is fixedly connected to the outer side of the cylinder rod 116. One end of the cylinder rod 116 is fixedly connected to one end of the receiving rack 110. The top of the receiving rack 110 is provided with a semi-circular plate 111, and the top of the receiving rack 110 is fixedly connected to the bottom of the semi-circular plate 111.

[0026] When using the main body 114 of this type of air pump strength testing equipment, firstly, a testing platform 11 is designed, with two side plates 12 symmetrically connected to the top side of the testing platform 11. The top ends of the two side plates 12 are fixedly connected to a fixing frame 13. The fixing frame 13 is designed with a placement seat 14, which is rectangular in shape and has multiple grooves. By gradually placing the air pump into the placement seat in a horizontal manner, since the middle part of the air pump body is the part that is prone to bending and deformation during inflation, when the air pump is pushed forcefully... The middle part of the rod will bear a large bending moment. Therefore, a folding plate 113 is provided at the top of the side plate 12. The inner wall of one end of the folding plate 113 is connected to the testing equipment body 114. By extending the length of the testing equipment body 114, it contacts the air pump on the placement seat 14 and the middle part of the air pump. By applying pressure to the middle part of the rod during testing, the bending strength of the rod material can be tested to see if there is excessive bending or even breakage. When a defective air pump is detected, it can be removed from the placement seat 14.

[0027] After the testing is completed, in order to remove the tested air pumps from the mounting base 14, a gear 16 is installed on one side of the mounting base 14. To drive the gear 16, a sliding plate 115 is provided on the inner wall of the bottom of the fixing frame 13. The other end of the sliding plate 115 is connected to a receiving rack 110. The receiving rack 110 has four rows of receiving holes, nine in each row, corresponding to the grooves on the mounting base 14. At the same time, a toothed plate 17 is designed on one side of each row. The bottom ends of the four toothed plates 17 are uniformly connected to the bracket 18. Therefore, by extending the length of the cylinder rod 116, the receiving rack 110 is shortened from its original position. During the movement, the toothed plate 17 will mesh with the gear 16. Since the gear 16 is fixedly connected to the positioning seat 14, the positioning seat 14 will gradually change its angle from the water surface, with a maximum angle change of 60 degrees. When the tail end of the toothed plate 17 meshes with the gear 16, the first row of holes on the receiving rack 110 has slid out from under the fixed frame 13. At the same time, the angle of the positioning seat 14 is tilted, so that the air pump smoothly enters the first row of holes under the influence of the slope. The material is unloaded by tilting the positioning seat 14 and sliding with gravity, avoiding scratches, deformation and other damage that may be caused to the surface of the air pump by mechanical gripping or collision, thus protecting the appearance and performance of the product to the greatest extent.

[0028] Among them, a semi-circular plate 111 is designed at the top of the receiving rack 110. The design of the semi-circular plate 111 can effectively ensure that the air pump can smoothly enter the receiving rack 110 after the receiving rack 110 slides out. The semi-circular plate 111 can effectively guide it to fall accurately into the receiving hole, avoiding falling off or jamming due to angle deviation.

[0029] When it is necessary to return the seat 14 to a horizontal position, the telescopic rod 19 is retracted, causing the bracket 18 and the toothed plate 17 to move down synchronously. As a result, the toothed plate 17 and the gear 16 disengage their transmission capability. At this time, one end of the seat 14 will naturally return to a horizontal position with the fixed frame 13 under the action of gravity.

[0030] Example 2: Please refer to Figures 2-4 The protective mechanism 2 includes a rubber plate 21, a connecting block 22 is provided on the bottom side of the rubber plate 21, the bottom side of the rubber plate 21 is fixedly connected to the top of the connecting block 22, the bottom end of the connecting block 22 is fixedly connected to the inner side of the receiving rack 110, and the inner side of the receiving rack 110 is fixedly connected to one end of the rubber plate 21.

[0031] A rubber plate 21 is designed on the inner side of the receiving rack 110, and multiple connecting blocks 22 are installed on the bottom side of the rubber plate 21. There is a certain distance between the connecting blocks 22. In this way, when the air pump enters the receiving rack 110, the rubber plate 21 and the spaced connecting blocks 22 form a composite structure of flexible buffer layer and elastic support point. When the air pump falls into the receiving rack 110, the soft material of the rubber plate 21 first dissipates most of the impact force, and then the connecting blocks 22 further disperse the remaining force through elastic deformation, realizing multi-level buffering of the end of the air pump, effectively avoiding problems such as end deformation and breakage caused by rigid collision.

[0032] Please see Figures 1-5The air pump is gradually placed horizontally into the placement frame. Since the middle section of the air pump is prone to bending and deformation during inflation, it experiences a significant bending moment when pushed forcefully. Therefore, a folding plate 113 is provided at the top of the side plate 12. One end of the folding plate 113 is connected to the inner wall of the detection device body 114. The detection device body 114 is extended to contact the air pump on the placement seat 14, specifically the middle section of the air pump. A gear 16 is installed on one side of the placement seat 14. To enable the gear 16 to drive, a sliding plate 115 is provided on the inner wall of the bottom of the fixing frame 13. The other end of the sliding plate 115 is connected to a receiving rack 110. The receiving rack 110 has four rows of receiving holes, nine in each row, corresponding to the grooves on the placement seat 14. Additionally, a receiving hole is provided on one side of each row. The device includes four toothed plates 17, the bottom ends of which are uniformly connected to the bracket 18. Therefore, by extending the length of the cylinder rod 116, the receiving rack 110 can move a short distance from its original position. During the movement, the toothed plates 17 will mesh with the gear 16. Since the gear 16 is fixedly connected to the positioning seat 14, the positioning seat 14 will gradually change angle from the water surface. When the tail end of the toothed plate 17 meshes with the gear 16, the first row of holes on the receiving rack 110 has slid out from under the fixed frame 13. At the same time, the angle of the positioning seat 14 is tilted, so that the air pump can smoothly enter the first row of holes under the influence of the slope. A semi-circular plate 111 is designed at the top of the receiving rack 110. The design of the semi-circular plate 111 can effectively ensure that the air pump can smoothly enter the receiving rack 110 after the receiving rack 110 slides out.

[0033] A rubber plate 21 is designed on the inner side of the receiving rack 110, and multiple connecting blocks 22 are installed on the bottom side of the rubber plate 21. There is a certain distance between the connecting blocks 22. In this way, when the air pump enters the receiving rack 110, the rubber plate 21 and the spaced connecting blocks 22 form a composite structure of flexible buffer layer and elastic support point. When the air pump falls into the receiving rack 110, the soft material of the rubber plate 21 first removes most of the impact force, and then the connecting blocks 22 further disperse the remaining force through elastic deformation, realizing multi-level buffering of the end of the air pump.
