Description

Technical Field

[0001] The utility model relates to the technical field of junction box installation, and specifically relates to a positioning clip for junction box installation. Background Technique

[0002] When a junction box is being produced and processed, sealant needs to be applied to the position where the upper end of the box body contacts the box cover. When applying the sealant, a fixture is required to fix the junction box to facilitate the sealant application process. However, in existing equipment, the fixture that only uses a hydraulic cylinder for positioning has problems such as slow telescopic speed of the hydraulic cylinder and low efficiency. If there is an operation error, there is also a risk of squeezing and damaging the junction box.

[0003] The Chinese patent discloses a junction box installation fixture (authorization announcement number CN219648008U). Through the cooperation of a slider, a cross plate and a positioning rod, this patented technology can adjust the position of the clamping plate according to the width of the junction box. Then, by pushing the pull rod, the pull rod drives the clamping plate to move, and the locking frame can lock the trapezoidal block on the pull rod, thereby realizing the locking of the pull rod. When the clamping plate fits with the junction box, the push of the pull rod can be stopped, that is, the clamping of the junction box is completed, replacing the traditional hydraulic cylinder clamping mode. It can not only speed up the clamping speed but also prevent the situation of squeezing and damaging the junction box due to operation errors.

[0004] However, it has certain drawbacks: When positioning the junction box, it is necessary to first pull out four positioning rods to adjust the positions of the four clamping structures in the left - right direction, and then move the four clamping plates to position the junction box. The movement of the four clamping plates needs to be synchronized. When disassembling the junction box, it is necessary to pull up the ejector rods one by one and then pull the pull rod. Therefore, the entire operation procedure is too cumbersome and complex, and the positioning speed of the junction box is relatively slow. Content of the Utility Model

[0005] The purpose of the utility model is to provide a positioning clip for junction box installation to solve the problems raised in the above - mentioned background technique.

[0006] To achieve the above - mentioned purpose, the utility model provides the following technical solution:

A plurality of rolling elements are evenly arranged on one side surface of the first clamping plate. Two second sliding holes are symmetrically opened on the left - hand surface of the positioning frame. A second slider is slidably connected inside the second sliding hole. A second clamping plate is installed at the right - hand end of the second slider. Tightening mechanisms are arranged between the two first sliding holes on the front surface of the positioning frame and between the two second sliding holes on the left - hand surface of the positioning frame.

Specific embodiments

[0021] Please refer to Figures 1 to 3 and Figure 5 In the embodiment of the present utility model, a positioning clip for junction box installation includes a positioning frame 1. Two first sliding holes 2 are symmetrically opened on the front surface of the positioning frame 1. A first slider 3 is slidably connected inside the first sliding hole 2. The rear end of the first slider 3 is installed with a first clamping plate 4. The rear end of the first clamping plate 4 is slidably connected to the inner rear surface of the positioning frame 1. A plurality of rolling members 5 are evenly arranged on one side surface of the first clamping plate 4. The rolling member 5 includes a support rod 6. The support rod 6 is movably embedded in one side surface of the first clamping plate 4. Both the upper and lower ends of the support rod 6 are rotatably connected with a support column 7. The support column 7 is installed inside one side surface of the first clamping plate 4. Two second sliding holes 8 are symmetrically opened on the left side surface of the positioning frame 1. A second slider 9 is slidably connected inside the second sliding hole 8. The right end of the second slider 9 is installed with a second clamping plate 10. The right end of the second clamping plate 10 is slidably connected to the inner right side surface of the positioning frame 1. The first clamping plate 4 is movably penetrated and connected to the second clamping plate 10;

[0022] The junction box 19 that needs to be sealed with sealant is placed in the positioning frame 1;

[0023] At the same time, moving the two first sliders 3 towards the middle can drive the first clamping plate 4 to limit the left and right directions of the junction box 19; at the same time, moving the two second sliders 9 towards the middle can drive the second clamping plate 10 to limit the front and back directions of the junction box 19. Due to the existence of the rolling member 5, the second clamping plate 10 can drive the junction box 19 to generate displacement in the front and back directions;

[0024] The rolling member 5 can also be a ball, and the ball is movably embedded inside the surface of the first clamping plate 4.

[0025] In Figure 1 , Figure 4 and Figure 5In the middle: Tightening mechanisms 11 are provided both on the front surface of the positioning frame 1 between the two first sliding holes 2 and on the left side surface of the positioning frame 1 between the two second sliding holes 8. The tightening mechanism 11 includes a fixed box 12. One end of the fixed box 12 is installed on the outer surface of the positioning frame 1. A motor 13 is installed inside the fixed box 12. A first gear 14 is installed at the output end of the motor 13. Two rotating rods 15 are symmetrically and rotatably connected to the lower surface inside the fixed box 12. A second gear 16 is installed at the upper end of the rotating rod 15. The first gear 14 is meshed with the second gear 16. Two baffles 17 are installed on the outer part of the rotating rod 15. A pulling rope 18 is wound between the two baffles 17 on the outer part of the rotating rod 15. The pulling rope 18 movably penetrates through one side surface of the fixed box 12. The pulling rope 18 in the front fixed box 12 is connected to the first slider 3, and the pulling rope 18 in the left fixed box 12 is connected to the second slider 9;

[0026] One end of the fixed box 12 away from the positioning frame 1 is installed with an openable box cover, which is convenient for maintaining its interior;

[0027] The motor 13 is a forward and reverse motor with a self-locking function. After power-off, its rotating shaft cannot rotate;

[0028] When the two rotating rods 15 rotate, the pulling ropes 18 can be released or wound up simultaneously. When wound up, the two first sliders 3 can be driven to approach simultaneously, or the two second sliders 9 can be driven to approach simultaneously, so as to realize the clamping and positioning of the junction box 19.

[0029] The working principle of the present utility model is as follows: When in use, the staff places the junction box 19 in the positioning frame 1, then turns on the front motor 13 to drive the first gear 14 to rotate. The second gear 16 will drive the rotating rod 15 to rotate. The two rotating rods 15 simultaneously wind up the pulling ropes 18, so as to pull the two first sliders 3 towards the middle. The two first sliders 3 will drive the two first clamping plates 4 to approach until the support rod 6 fits against the junction box 19. Then turn on the left motor 13 to drive the first gear 14 to rotate. The second gear 16 will drive the rotating rod 15 to rotate. The two rotating rods 15 simultaneously wind up the pulling ropes 18, so as to pull the two second sliders 9 towards the middle. The two second sliders 9 will drive the two second clamping plates 10 to approach, push the junction box 19 to the center position and clamp it. Finally, the staff can use the gluing device to glue the junction box 19.
