[0002] Weak current generally refers to DC circuits or audio, video lines, network lines, and telephone lines, and the AC voltage is generally within 36 V. Household appliances such as telephones, computers, and television signal inputs (cable TV lines), and audio equipment (output lines) are all weak current electrical equipment.

[0003] Patent No.: CN218005818U, discloses a pre-buried structure for weak-current casing. PPR pipes can be made from local materials and scraps, which is green and environmentally friendly. In addition, the pre-buried structure for weak-current casing adopts prefabricated parts, which can be transported to the site for construction and are easy to operate. In addition, the pre-buried structure for weak-current casing is tightly sealed and has a good anti-seepage effect.

[0004] However, during the implementation of this plan, since there is no structure to seal the grouting material inside the PPR pipe, when the grouting material is poured into the PPR pipe, due to the fluidity of the grouting material, it will flow freely in the PPR pipe, resulting in excessive pouring of grouting material in the PPR pipe, resulting in a waste of grouting material and resources, and then a pre-buried structure of a weak current casing is proposed. Utility Model Content

[0013] Preferably, a spring is fixedly connected to the surface of the movable plate, and one end of the spring away from the movable plate is fixedly connected to the inside of the fixing ring.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The pre-buried structure of the weak-current bushing blocks the pouring grouting material under the blocking of the first blocking plate and the second blocking plate, thereby preventing the pouring grouting material from flowing randomly, thereby ensuring the filling efficiency and filling effect of the pouring grouting material, thereby blocking the gap between the pipeline and the weak-current wire again, and further improving the anti-seepage effect of the device.

[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a pre-buried structure of a weak current bushing, comprising a steel plate 2, a mounting hole 3 penetrating the surface of the steel plate 2, a bushing 1 arranged inside the mounting hole 3, a first sealing plate 6 slidably connected to the inner wall of the bushing 1, a PPR pipe 8 is fixedly connected to the inside of the first sealing plate 6, a second sealing plate 10 is fixedly connected to the end of the PPR pipe 8 away from the first sealing plate 6, the surface of the second sealing plate 10 is also slidably connected to the inner wall of the bushing 1, and then, through the arrangement of the second sealing plate 10 and the first sealing plate 6, the two ends of the filling area of ​​the casting grouting material in the bushing 1 can be blocked, thereby avoiding the casting grouting material from flowing randomly in the bushing 1, thereby causing waste of casting grouting material and slow grouting speed in the bushing 1, thereby improving the use effect of the device, and improving the promotion value and practicality of the device.

[0024] The surface of the casing 1 is provided with a pouring port 5 penetrating through the surface of the casing 1 , and the pouring port 5 is provided to provide a pouring port for pouring grouting material.

[0025] Furthermore, the inner wall of the PPR pipe 8 is slidably connected to a blocking cover 7, and the PPR pipe 8 can be blocked by the setting of the blocking cover 7, thereby preventing the poured grouting material from entering the PPR pipe 8, thereby preventing the subsequent laying of wires in the PPR pipe 8, thereby ensuring the smooth laying of the wires.

[0026] The surface of the first sealing plate 6 and the surface of the second sealing plate 10 are both fixedly connected with a rubber sleeve 9, and through the setting of the rubber sleeve 9, the gap between the sleeve 1 and the first sealing plate 6 and the second sealing plate 10 can be filled, thereby avoiding overflow of the grouting material in the sleeve 1, thereby reducing the waste of the grouting material and improving the use effect of the device.

[0027] A fixing ring 4 is fixedly connected to the surface of the sleeve 1, and an engaging block 11 equidistantly arranged in a circle is slidably connected to the surface of the fixing ring 4. One side of the engaging block 11 is an inclined surface, and an engaging groove 12 is provided on the surface of the engaging block 11. The engaging groove 12 is consistent with the inner wall of the mounting hole 3, so that the steel plate 2 can be inserted into the engaging groove 12, so that the sleeve 1 and the steel plate 2 can be connected together, thereby improving the connection strength between the sleeve 1 and the steel plate 2.

[0028] A movable plate 14 is fixedly connected to the surface of the engaging block 11, and the surface of the movable plate 14 is slidably connected to the inside of the fixed ring 4. A spring 13 is fixedly connected to the surface of the movable plate 14, and one end of the spring 13 away from the movable plate 14 is fixedly connected to the inside of the fixed ring 4 to reset the engaging block 11.

[0029] Specifically, when in use, the sleeve 1 is inserted into the mounting hole 3. As the sleeve 1 is inserted, the inclined surface of the engaging block 11 on the fixing ring 4 contacts the inner wall of the mounting hole 3, so that the engaging block 11 is pressed into the fixing ring 4, and the moving plate 14 is driven to move in the fixing ring 4, compressing the spring 13, and then as the sleeve 1 moves, the engaging groove 12 corresponds to the inner wall of the mounting hole 3, so that at this time, under the elastic force of the spring 13, the engaging block 11 returns to its original state, so that the inner bottom wall of the engaging groove 12 fits with the inner wall of the mounting hole 3, thereby achieving the sleeve. 1 is positioned, and then the staff can insert the blocking cover 7 into the PPR pipe 8 to seal the PPR pipe 8, and then the pouring grouting material can be injected into the sleeve 1 through the injection port 5 to fill the gap between the PPR pipes 8, and under the blocking of the first blocking plate 6 and the second blocking plate 10, the pouring grouting material is blocked to avoid the random flow of the pouring grouting material, thereby ensuring the filling efficiency and filling effect of the pouring grouting material, thereby again blocking the gap between the pipeline and the weak current wire, and again improving the anti-seepage effect of the device.

[0030] Working principle: insert the sleeve 1 into the mounting hole 3. As the sleeve 1 is inserted, the inclined surface of the engaging block 11 on the fixing ring 4 contacts the inner wall of the mounting hole 3, so that the engaging block 11 is pressed into the fixing ring 4, and drives the movable plate 14 to move in the fixing ring 4 to compress the spring 13. Then, as the sleeve 1 moves, the engaging groove 12 corresponds to the inner wall of the mounting hole 3. At this time, under the elastic force of the spring 13, the engaging block 11 returns to its original state, so that the inner bottom wall of the engaging groove 12 fits with the inner wall of the mounting hole 3, thereby realizing the positioning of the sleeve 1. Then the staff can insert the sealing cover 7 into the PPR pipe 8 to close the PPR pipe 8. Then, the pouring grouting material can be injected into the sleeve 1 through the pouring port 5 to fill the gap between the PPR pipes 8, and under the blocking of the first sealing plate 6 and the second sealing plate 10, the pouring grouting material is blocked to avoid the random flow of the pouring grouting material.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
