[0021] The following is in conjunction with the appendix Figure 1-7 The specific embodiments of this utility model will be described in detail.

[0022] This utility model provides a tensile testing fixture for photovoltaic panel module cables, including a fixed clamp 1 and a fixed frame 4. A slide rail 6 is fixedly installed on the front of the fixed frame 4, and a slider assembly 7 is slidably sleeved on the slide rail 6. A configuration platform 10 is fixedly connected to one side of the slider assembly 7, and a connecting shaft 9 is provided on the top of the configuration platform 10. An adjustable stroke cylinder 5 is fixedly installed on the front of the fixed clamp 1, and the output end of the adjustable stroke cylinder 5 is connected to the slider assembly 7. Several guide pulleys 3 are provided on the fixed clamp 1. A steel wire 2 is fixedly installed at one end of the fixed clamp 1, and the other end of the steel wire 2 passes through several guide pulleys 3 and is connected to the top of the connecting shaft 9. The other end of the fixed clamp 1 is used to connect the test cable, and several counterweights 8 are sleeved on the side wall of the connecting shaft 9.

[0023] During use, the test cables on the photovoltaic panel assembly need to be installed on the fixed clamp 1. Under the connection of the guide pulley 3, the weight of the counterweight 8 on the configuration platform 10 can be converted into the tension of the fixed clamp 1 on the test cable, thereby achieving the tension detection effect. By installing or removing several counterweights 8 on the side wall of the connecting shaft 9, the tension can be adjusted, making the device more flexible to use. In addition, during the test, the adjustable stroke cylinder 5 controls the intermittent up and down movement of the configuration platform 10, which can apply tension to the gap of the test cable, realize dynamic detection, and make the device more comprehensive in detecting cable tension. The adjustable stroke cylinder 5 is model: MBW-Z / MDBW-Z-cylinder / standard type: double rod double action.

[0024] Furthermore, the slide rail 6 includes a mounting plate 61, with a T-shaped rail 62 fixedly connected to one side of the mounting plate 61. The slider assembly 7 consists of a top slider 71 and a locking slider 72, both of which are slidably sleeved on the side wall of the T-shaped rail 62. A connecting end 711 is provided on the top of the top slider 71, and the connecting end 711 is fixedly installed with the output end of the adjustable stroke cylinder 5. The configuration table 10 is fixedly installed on one side of the top slider 71 and the locking slider 72, and the locking slider 72 is used to lock the vertical position of the configuration table 10.

[0025] When the device is not in use, the mounting platform 10 slides down under the action of gravity, applying gravity to the adjustable stroke cylinder 5. Over time, this accelerates the wear and tear on the components of the adjustable stroke cylinder 5 and affects its service life. By setting a locking slider 72, the mounting platform 10 can be locked in position, so that when the tooling is not in use, the mounting platform 10 can be prevented from applying force to the adjustable stroke cylinder 5.

[0026] Furthermore, a number of pin holes 63 are provided on one side of the T-shaped rail 62; the locking slider 72 includes a main slider 720, a protrusion 721 is fixedly connected to one side of the main slider 720, the protrusion 721 is provided with a post hole that communicates with the inside of the main slider 720, a telescopic pin 722 is provided in the post hole, and an elastic pin head 723 is provided at the output end of the telescopic pin 722.

[0027] When the locking slider 72 is running, it extends by operating the telescopic pin 722. The telescopic pin 722 drives the elastic pin head 723 to move and embed into the pin hole 63, thus achieving the locking effect of the locking slider 72. Since the elastic pin head 723 is elastic, when the elastic pin head 723 is misaligned with the pin hole 63, the elastic pin head 723 abuts against the side wall of the T-shaped rail 62 and retracts. The position is adjusted by the sliding adjustment of the slider assembly 7. When the elastic pin head 723 overlaps with the pin hole 63, the elastic force of the elastic pin head 723 can automatically embed into the pin hole 63.

[0028] Furthermore, one end of the protrusion 721 has a through hole extending into the post hole; the telescopic pin 722 includes a movable pin 724, a knob 725, and a threaded pin 726. The knob 725 is rotated and sleeved in the through hole, the threaded pin 726 is fixedly connected to one end of the knob 725, the movable pin 724 is threaded and sleeved on the side wall of the threaded pin 726, the movable pin 724 is slidably sleeved in the post hole of the protrusion 721, and the elastic pin head 723 is disposed at one end of the movable pin 724.

[0029] In use, rotating the knob 725 drives the threaded column 726 to rotate. Under the action of the threaded structure, the movable column 724 can be displaced, which in turn drives the elastic pin head 723 to be displaced.

[0030] Furthermore, the elastic pin 723 includes a movable block 727, a spring 728, and a main pin 729. One end of the movable column 724 has a sliding hole, and the movable block 727 is slidably sleeved in the sliding hole of the movable column 724. The main pin 729 is fixedly connected to one side of the movable block 727, and the other end of the movable block 727 is connected to the inner wall of the sliding hole through the spring 728.

[0031] When the elastic pin 723 is misaligned with the pin hole 63 during use, the main pin 729 is pressed, causing the moving block 727 to slide. The moving block 727 then compresses the spring 728. When the elastic pin 723 overlaps with the pin hole 63, the main pin 729 is reset and inserted into the pin hole 63 under the elastic force of the spring 728, thus achieving the elastic effect of the elastic pin 723.

[0032] Furthermore, a positioning groove is provided in the post hole of the protrusion 721, and a positioning crossbar is provided on the side wall of the movable post 724, which slides in the positioning groove.

[0033] This setting prevents the movable column 724 from rotating with the threaded column 726 due to friction, thus avoiding affecting the displacement of the movable column 724.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. This utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
