Description

Technical Field

[0001] The utility model patent relates to automobile handle test and detection equipment, specifically to an automobile trunk carpet handle test machine. Background Art

[0002] The main function of a car trunk carpet is to separate the lower space from the upper space of the trunk. Generally, the lower space of a car trunk is used to place spare tires and storage boxes. The trunk carpet can be used to divide the space in the trunk, making it easier to store items separately and keep the trunk clean and tidy. When people want to take out the spare tire or other items under the trunk carpet, they can use the handle on the carpet to open the carpet.

[0003] At present, the trunk carpet handles used in most models on the market are mainly nylon straps and plastic handles. During the production process, testing the bearing capacity of the trunk carpet handle and the firmness of the connection between the handle and the carpet is one of the important indicators for evaluating the quality of the carpet handle.

[0004] In the patent document named "Safety Handle Static Load Test Device" (document number CN202305327U), it includes a safety handle, a base and a stretching machine. Both ends of the safety handle are fixedly connected to the surface of the base. The stretching machine pulls the handle through a pull belt to realize the static load test of the handle.

[0005] In the patent document entitled "A Car Handle Usage Times Tester" (document number CN218035638U), the handle 4 is placed on the mounting plate 3 so that the through hole 411 and the mounting threaded hole 31 are in relative positions, then the mounting bolt 11 is passed through the through hole 411 and tightened in the mounting threaded hole 31, then one end of the traction member 8 is passed through the mounting cavity and the other end is passed through the lifting ring 7, then the round hair portion 81 is adhered to the barbed hair portion 82, and finally the control cylinder 10 is used to control the piston rod to drive the movable plate 5 to move downward, pull the handle 4 to flip downward, and then the movable plate 5 is pushed upward to slide with the help of the piston rod, and the handle 4 can automatically rebound and reset, and this cycle is repeated to test the number of times the handle 4 is used.

[0006] The handle inspection equipment mentioned above is all aimed at inspecting the structural strength of the handle body, in which the handle is usually fixed by bolts. In batch inspection operations, the repeated disassembly and assembly of bolts brings great inconvenience to the inspection operation. In addition, when inspecting the trunk carpet handle, the traditional nylon handle is connected to the carpet by sewing, while the plastic handle is mostly hinged to a specific frame on the carpet, and the handle can be pulled up when used. For this reason, there are no corresponding holes on the carpet or carpet handle to insert the fixing bolts required for inspection, making it difficult to use the above method for fixing and inspection. Summary of the invention

[0007] The utility model provides a car trunk carpet handle testing machine, which can perform tension testing on the trunk carpet handle and meet the needs of rapid disassembly and assembly.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted is: a car trunk carpet handle testing machine, including a tensile testing machine, a traction part located on the body of the tensile testing machine moves up and down along the body, the upper end surface of the base of the tensile testing machine is connected to a panel with a flat surface, and two mutually parallel fixing rods are arranged parallel to the upper surface of the panel and at a distance from each other above the panel, and the rod bodies of the two fixing rods are located in the horizontal direction and are arranged at the same height and at a distance from each other.

[0009] Compared with the prior art, the technical effect of the utility model is as follows: by providing two mutually parallel fixing rods arranged at a parallel interval above the panel, a partial carpet sample block carrying a handle can be inserted into the gap between the fixing rod and the panel. When the traction part pulls the handle, the fixing rod can form a block for the carpet sample block, restricting the upward movement of the carpet sample block, that is, achieving the fixation of the carpet sample block machine handle; conversely, the fixation of the carpet sample block can be canceled by pulling the carpet sample block out of the gap. The whole does not need to be fixed with bolts, and the carpet handle is easy to detect and disassemble, which solves the problem that the carpet handle is inconvenient to fix during the bearing capacity test, thereby facilitating the detection of the bearing capacity and connection firmness of the handle.

[0019] The following is combined with Figure 1-9 And related content, the utility model is further described in detail:

[0020] A car trunk carpet handle testing machine comprises a tensile testing machine 10. A traction part 12 located on the body of the tensile testing machine 10 moves up and down along the body. A panel 21 with a flat surface is connected to the upper end surface of a tensile testing machine base 11. Two mutually parallel fixing rods 23 are arranged parallel to the upper surface of the panel 21 and at a distance from each other. The rod bodies of the two fixing rods 23 are located in the horizontal direction and are arranged at the same height and at a distance from each other.

[0021] In the above scheme, when testing the bearing capacity of the trunk carpet handle, a carpet sample block A1 with a size of about 350 mm × 200 mm is taken with the handle A2 as the center. Figure 5 , 6 As shown in Figures 7 and 8, a partial carpet sample block A1 with a handle A2 can be inserted into the gap between the fixed rod 23 and the panel 21. When the traction part 12 pulls the handle A2, the handle A2 is in the shape of a U-shaped rod, and the U-shaped rod surface of the handle A2 is placed upright and located between the two fixed rods 23. The traction part 12 is connected to the middle position of the handle A2, and a pulling force is applied upward in the vertical direction, which gradually increases until the handle A2 is severely deformed, damaged and broken, or falls out of the gap between the panel 21 and the fixed rod 23, and the pulling force value is recorded. During the detection process, the fixed rod 23 can form a barrier on the two side areas of the carpet sample block A1, restricting the carpet sample block A1 from moving upward, that is, achieving the fixation of the carpet sample block A1 and the handle A2; conversely, the carpet sample block A1 can be pulled out of the gap to cancel its fixation. The area between the coplanar areas of the panel 21 and the fixing rod 23 constitutes an area for constraining the up and down displacement of the carpet sample block A1. The front, left and right sides of the area are open on three sides. The carpet sample block A1 can be inserted or extracted from the open areas on the front, left and right sides at will, so that it can be freely taken in and out, thereby improving the test efficiency.

[0022] Furthermore, in order to facilitate the arrangement of the fixing rod 23, a vertical plate 22 whose surface is perpendicular to the rod body of the fixing rod 23 is connected to one side of the panel 21, the top of the vertical plate 22 protrudes upward and is higher than the upper surface of the panel 21, and the end of the fixing rod 23 adjacent to the vertical plate 22 is connected to the vertical plate 22. The vertical plate 22 serves as a carrier of the fixing rod 23, which facilitates the position of the fixing rod 23. Except for the vertical plate 22, the other side positions of the panel 21 are all vacant, and the carpet sample block A1 can be selectively placed from the vacant side of the panel 21 into the gap between the panel 21 and the fixing rod 23 as needed.

[0023] Combination Figure 3 ,4 As shown, in order to facilitate the disassembly and assembly between the fixing rod 23 and the vertical plate 22, two fixing holes 221 for the two fixing rods 23 to penetrate are provided on the plate surface of the vertical plate 22, and two nuts 231 sleeved on the rod body of the fixing rod 23 are clamped against the opposite side plate surface of the vertical plate 22 and form a threaded fit with the fixing rod 23. By pressing the opposite side plate surface of the vertical plate 22 with the two nuts 231 arranged oppositely, the fixing rod 23 matched therewith can be firmly fixed on the vertical plate 22; conversely, by removing the nuts 231 from the fixing rod 23, the fixing rod 23 can be pulled out from the corresponding fixing holes 221, thereby realizing the disassembly of the fixing rod 23 and the vertical plate 22.

[0024] As a preferred solution, the two fixing holes 221 are waist-shaped holes with the same hole core height, and the long diameter direction of the waist-shaped holes is located in the horizontal direction parallel to the upper plate surface of the panel 21. By loosening the nut 231, the locking state between the fixing rod 23 and the vertical plate 22 can be cancelled, and the two fixing rods 23 can slide toward or away from each other in the waist-shaped holes. According to the specific size of the carpet sample block A1 or the handle A2, the relative position between the two fixing rods 23 and the carpet sample block A1 can be adjusted to meet the reasonable limit requirements of the carpet sample block A1.

[0025] In addition, in order to facilitate the disassembly and assembly between the panel 21 and the tensile machine base 11, Figure 7 , 8 As shown in FIG. 9 , the lower surface of the panel 21 and the upper end surface of the tensile machine base 11 are provided with vertical pins 24 and sleeves 30, the pins 24 are inserted into the sleeves 30, and a limit fit is provided between the two to limit the upward and downward displacement of the pins 24. The sleeves 30 can position the pins 24, and the two can be quickly connected and positioned by plugging.

[0026] Furthermore, the position-limiting cooperation includes a latch 40, and a pin hole 241 and a plug hole 31 are respectively provided on the pin column 24 and the sleeve 30 in the radial direction, and the latch 40 is inserted into the pin hole 241 and the plug hole 31 arranged concentrically. The insertion of the latch 40 can limit the relative displacement of the pin column 24 and the sleeve 30, thereby realizing the locking of the pin column 24, and ensuring that the panel 21 is stably connected to the base 11 of the tensile machine; conversely, by pulling the latch 40, it can be withdrawn from the pin hole 241 and the plug hole 31, thereby canceling the restriction on the relative displacement of the pin column 24 and the sleeve 30 up and down, and the pin column 24 can be removed from the sleeve 30, so that the panel 21 can be separated from the base 11 of the tensile machine, and the tooling can be disassembled and assembled at any time, which is convenient for use.
