The lower slider component 310 is movably connected to the second slide rail 112 and is provided with a second fixing rod group and a third fixing rod group with one end extending to the top of the frame 110. The lower slider component 310 can be an integral component connected to the two second slide rails 112, or can adopt a split structure. For example, the lower slider component 310 is two and is respectively connected to the second slide rails 112 on the two longer second horizontal rods in the smaller rectangle. The upper slider component 320 can also be an integral component connected to the two first slide rails 111, or can adopt a split structure. For example, the upper slider component 320 is two and is respectively connected to the first slide rails 111 arranged on the two longer first horizontal rods in the larger rectangle.

[0058] The upper slider assembly 320 is movably connected to the first slide rail 111 and is provided with a second fixed cover assembly 321 that can be rotated to the top of the second fixed rod group and the third fixed rod group to connect the lower slider assembly 310. The second fixed cover assembly 321 is adapted to the top of the second fixed rod group and the third fixed rod group to realize the opening and closing of the free ends of the second fixed rod group and the third fixed rod group. The tension assembly 400 is connected to the third fixed rod group to drive the lower slider assembly 310 to move along the extension direction of the second slide rail 112 and the upper slider assembly 320 to move along the extension direction of the first slide rail 111.

[0059] Taking into account that the automobile chain seat cover is an approximately quadrangular prism structure, the first fixing rod group includes two parallel and spaced first rod bodies 211, and the second fixing rod group includes two parallel and spaced second rod bodies 3111. The automobile chain seat cover is supported by four rod bodies. At the same time, taking into account the unevenness of the automobile seat, in order to simulate the actual situation of the automobile seat, a number of nylon sleeves 500 are provided on the first rod body 211 and the second rod body 3111. Through the tightening screws on the nylon sleeves 500, all the nylon sleeves 500 can be moved up and down relative to the first rod body 211 and the second rod body 3111.

[0060] See also Figure 7 In this embodiment, the frame assembly 100 also includes a box body 120 adjacent to the frame body 110, and a placement table 121 is provided on the top of the box body 120. The tension assembly 400 includes a linear module 410, a first fixing member 420 and a transmission assembly 430. The linear module 410 is installed on the placement table 121; a second fixing member 421 is provided on the top of the first fixing member 420, and the second fixing member 421 is provided with a first groove, and the first groove includes a larger first end and a smaller second end, and the second end is connected to the first end and the outside of the first groove; the transmission assembly 430 includes a third fixing member 431 and The fourth fixing member 432 and the third fixing member 431 are provided with a first protrusion 4311 adapted to the first groove at one end to connect the second fixing member 421; one end of the fourth fixing member 432 is connected to the end of the third fixing member 431 away from the second fixing member 421, and the other end of the fourth fixing member 432 is provided with a limiting structure 4321 adapted to the third fixing rod group, which is connected to the second fixing member 421 and the third fixing rod group through the transmission assembly 430, so that the third fixing rod group moves with the first fixing member 420. The power source of the first fixing member 420 can be a linear motor, etc., as long as it can achieve the above-mentioned purpose.

[0061] Among them, the third fixed rod group includes a plurality of third rod bodies 3121 extending vertically. The limiting structure 4321 is provided with a plurality of first through holes extending vertically. The first through holes correspond to the third rod bodies 3121 one by one. By passing the third rod bodies 3121 through the corresponding first through holes, when the linear module 410 moves, it drives the movement of the third rod bodies 3121. The number of the third rod bodies 3121 can be set according to the number of the lower slider assemblies 310. When there are two lower slider assemblies 310 (split structure), each lower slider assembly 310 should be provided with a third rod body 3121, so that the third rod bodies 3121 driven by the limiting structure 4321 drive all the lower slider assemblies 310 to move synchronously, and further drive all the upper slider assemblies 320 to move synchronously.

[0062] In addition, considering the setting manner of the second rod body 3111 and the third rod body 3121 in the lower slider assembly, it is preferred that the lower slider assembly is provided with adjacent first fixing seats 3112 and second fixing seats 3122. The second rod body 3111 is fixed to the first fixing seat 3112, and the third rod body 3121 is fixed to the second fixing seat 3122.

[0063] In this embodiment, a first base 113 is provided at the top of the frame body 110. The first fixing cover group 220 includes a first rotating shaft 221 installed on the first base 113 and a first fixing cover 222 connected to the first rotating shaft 221. Considering various application scenarios, the first rotating shaft 221 can rotate relative to the first base 113 and the first fixing cover 222 to reduce the frictional consumption of the first rotating shaft 221 during rotation. In addition, the first rotating shaft 221 can also be fixedly arranged on one of the first base 113 and the first fixing cover 222 as long as the above purpose can be achieved; the upper slider assembly 320 is further provided with a second base 322. The second fixing cover group 321 includes a second rotating shaft 3211 installed on the second base 322 and a second fixing cover 3212 connected to the second rotating shaft 3211. Similarly considering various application scenarios, the second rotating shaft 3211 can rotate relative to the second base 322 and the second fixing cover 3212 to reduce the frictional consumption of the second rotating shaft 3211 during rotation. The first fixing cover 222 and the second fixing cover 3212 are both groove-shaped structures that can be buckled on the end of the rod body. After rotation, the first fixing cover 222 and the second fixing cover 3212 can, under their own gravity, make the groove-shaped structure seal the free end of the corresponding rod body.

[0064] Please refer to Figure 5 and Figure 6, It should be noted that the zipper detection device for automobile seat covers further includes an operation table 600 disposed on one side of the frame 110 through a fixing plate 610. A cover plate 660 is provided at the bottom of the operation table 600. Through the connection between the cover plate 660 and the fixing plate 610, the fixing plate 610 and the operation table 600 are relatively fixed. The fixing plate 610 is fixed to one side of the frame 110, and the fixing plate 610 is located above the box body 120, which is beneficial to saving the required space of the entire frame assembly 100. The box body 120 has a cavity structure for accommodating a circuit module. The operation table 600 is connected to the circuit module to control the movement of the first fixing member 420 connected to the circuit module.

[0065] In this embodiment, a tension sensor 433 capable of transmitting tension data is provided between the third fixing member 431 and the fourth fixing member 432. The operation table 600 is provided with a display screen 620 capable of displaying the detection value of the tension sensor 433, a first button 630 for pausing operation, a second button 640 for starting operation, and a third button 650 for controlling the movement of the first fixing member 420. The first button 630 is a stop button. Pressing it stops the device. The second button 640 is a start button. Pressing it starts the device. The third button 650 is a rotary switch. Rotating it left and right can manually control the left and right movement (horizontal movement) of the first fixing member 420.

[0066] In addition, pulleys 700 are provided at the bottoms of the frame 110 and the box body 120. The pulleys 700 can be Fuma wheels. They are fixed to the bottoms of the frame 110 and the box body 120 through Fuma wheels and have a braking function, enabling the fixing and movement of the zipper detection device for automobile seat covers.

[0067] In summary, adjust the nylon sleeve 500 to a suitable position, open the first fixing cover 222 and the second fixing cover 3212, and put a hidden automobile chain seat cover to be tested on the first rod 211 and the second rod 3111 from top to bottom. The nylon sleeve 500 plays a role in simulating the unevenness of the automobile seat. Then rotate the first fixing cover 222 to cover the first rod 211, and rotate the second fixing cover 3212 to cover the second rod 3111 and the third rod 3121. After setting the tension value through the display screen 620 and clicking start, the device starts. The tension assembly 400 will drive the upper slider assembly 320 and the lower slider assembly to move through the linear guide rail, tightening the hidden automobile chain seat cover. At this time, the current tension value is displayed on the display screen 620. Manually pull the pull head of the hidden automobile chain under the current tension value to test the smoothness of the zipper under the current value. It is also possible to detect the maximum tensile strength of the zipper stitches by modifying the tension value (for example, if the hidden automobile chain seat cover cracks at the zipper stitches or the chain tooth bite at a tension of 100KG, then the ultimate tensile strength of this product is 100KG).

[0068] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0069] The embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.

[0070] Specific examples are used in this article to elaborate on the principles and implementation manners of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the present utility model.
