[0023] The specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example:

[0025] As shown in the accompanying drawings, the specific embodiment of a fixing device for an embedded junction box of a precast concrete member of the present utility model is shown. Refer to Figure 1 and Figure 2 , which mainly includes a junction box 1, a clamping mechanism 2, an insertion plate 3, a ferrule mechanism 4, and a wall reinforcement 5. The junction box 1 and the clamping mechanism 2 are connected as a whole. The insertion plate 3 and the ferrule mechanism 4 are connected as a whole. The junction box 1 can be installed on the insertion plate 3 through the clamping mechanism 2, and the insertion plate 3 can be installed on the wall reinforcement 5 through the ferrule mechanism 4.

[0026] Refer to Figure 2 , Figure 3 , the clamping mechanism 2 is connected to the back of the junction box 1. The clamping mechanism 2 includes a connecting plate 201. The front part of the connecting plate 201 is fixedly connected to the back of the junction box 1. A transverse plate 202 is fixedly connected to the back of the connecting plate 201. Elastic pieces 203 are respectively provided at both ends of the transverse plate 202. The elastic pieces 203 are integrally formed with the transverse plate 202. A clamping block 204 is provided on each elastic piece 203. The distances between the two clamping blocks 204 and the center line of the connecting plate 201 are equal.

[0027] Refer to Figure 4 , Figure 5 , the insertion plate 3 includes an insertion plate body 301. A slot 303 is opened at the upper end of the insertion plate body 301. The upper end of the slot 303 communicates with the outside. An opening 304 communicating with the slot 303 is opened on the insertion plate body 301 above the slot 303. The width of the opening 304 is smaller than the width of the slot 303. The upper end of the opening 304 communicates with the outside. The size of the opening 304 is the same as the size of the connecting plate 201. Clamping holes 305 communicating with the slot 303 are respectively opened on the insertion plate body 301 on both sides of the opening 304. The distances between the two clamping holes 305 and the center line of the opening 304 are equal. The size of the clamping holes 305 is larger than the size of the clamping blocks 204, facilitating the smooth falling of the clamping blocks 204 into the clamping holes 305.

[0028] When the junction box 1 is connected to the plug board 3 through the clamping mechanism 2, the connecting plate 201 of the clamping mechanism 2 is aligned with the opening 304 of the plug board body 301, and the junction box 1 is slid so that its back is close to the plug board body 301 and slides. After the connecting plate 201 slides into the opening 304 for a distance, the block 204 will conflict with the plug board body 301. At this time, the sliding is stopped, and the spring pieces 203 at both ends of the cross plate 202 are slightly pressed down so that the block 204 can enter the slot 303. Then the junction box 1 is continued to slide, and the cross plate 202, the spring piece 203, and the block 204 are driven to slide in the slot 303. When the block 204 slides to the bottom of the card hole 305, the block 204 can use the elasticity of the spring piece 203 to bounce upward into the card hole 305, completing the positioning and installation of the junction box 1. At this time, the connecting plate 201 slides to the lower end of the opening 304, and the block 204 just falls into the card hole 305, with good installation accuracy.

[0029] Reference Figure 6 , Figure 7 , the clamping mechanism 4 is connected to the back of the plug board 3. The clamping mechanism 4 includes a plurality of connecting clamps 401, and a plurality of connecting grooves 302 are provided on the back of the plug board 3. The connecting clamps 401 are fixedly installed in the connecting grooves 302 one by one. The size and shape of the connecting grooves 302 are adapted to the connecting clamps 401, so that the connecting clamps 401 can be fitted with the connecting grooves 302. A notch 401a is provided at the bottom of each connecting clamp 401 along its length direction, and the length of the notch 401a is the same as that of the connecting clamp 401. The connecting clamp 401 is elastic, so that the connecting clamp 401 can be installed on the wall reinforcement 5 through the notch 401a.

[0030] Each connecting sleeve 401 is also provided with a matching tie head 402 and tie strip 403. The tie head 402 is fixedly connected to the outer surface of the connecting sleeve 401, and one end of the tie strip 403 is fixedly connected to the bottom of the connecting sleeve 401 inside the notch 401a. The installation position of the tie head 402 and the tie strip 403 is more convenient for tightening and installation. After the connecting sleeve 401 is sleeved on the wall reinforcement 5, the tie strip 403 can be pulled outward to bypass the wall reinforcement 5 and then inserted into the tie head 402 for tightening, which can play a further fixing role and ensure that the overall installation is more secure and will not move. In this embodiment, the tie head 402 and the tie strip 403 on each connecting sleeve 401 are arranged in two groups at intervals, which can also be adjusted as needed.

[0031] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical solution of the utility model should be included in the protection scope of the utility model.
