[0002] When traditionally installing PVC conduits and junction boxes within a wall after it has been built, the first step is to mark the location on the wall and then cut grooves.

[0019] The following will describe specific embodiments and appendices. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0020] This utility model provides an auxiliary device for fixing and plastering conduit boxes in post-construction walls (such as...). Figure 1As shown in the diagram, in practical applications, this utility model is mainly used to assist in the installation of conduits and junction boxes within the vertical wall grooves 81 opened in the post-built wall 8. It includes a mobile trolley 1, a square fixed sleeve 2, a square telescopic sleeve 3, a conduit fixing mechanism, a junction box fixing mechanism, a plastering mechanism, a laser level, and a battery. Both the square fixed sleeve 2 and the square telescopic sleeve 3 can be made from square steel pipes of a certain size. The mobile trolley 1 allows for flexible movement of the entire utility model, facilitating its handling and transportation. Simultaneously, it facilitates the adjustment of its construction position during construction. The square fixed sleeve 2 is fixedly installed... On the mobile trolley 1, the square telescopic sleeve 3 is vertically fitted inside the square fixed sleeve 2, and the square telescopic sleeve 3 can move up and down and be positioned within the square fixed sleeve 2. Specifically, a first electric push rod is fixedly installed on the outer wall of the square fixed sleeve 2, and the telescopic end of the first electric push rod is fixedly connected to the outer wall of the square telescopic sleeve 3. The battery provides power to the first electric push rod. In practical applications, by controlling the telescopic movement of the first electric push rod, the telescopic movement of the square telescopic sleeve 3 within the square fixed sleeve 2 is synchronously realized, and the self-locking function of the first electric push rod is used to realize the telescopic movement of the square telescopic sleeve 3. The telescopic sleeve 3 is positioned on the directional fixing sleeve 2. The conduit fixing mechanism, junction box fixing mechanism, and plastering mechanism are all located on the outer wall of the square telescopic sleeve 3. The plastering mechanism can move up and down and be positioned relative to the square telescopic sleeve 3. The conduit fixing mechanism is used to press and fix the conduit in the wall groove 81. The junction box fixing mechanism is used to clamp and fix the junction box in the wall groove 81. The plastering mechanism is used to smooth the mortar in the wall groove 81. In practical applications, after the junction box fixing mechanism and the conduit fixing mechanism are used to fix and position the conduit, the plastering mechanism can be used directly to plaster the wall. The grouting and leveling operation inside the groove 81 eliminates the need for a grouting and fixing process, thereby effectively improving the construction efficiency of embedding junction boxes and conduits within the wall groove 81. The laser level is used to calibrate the height of the junction box clamping and fixing mechanism. The laser level is a known mature technology product in this field. During construction, the laser level is first used to project a laser horizontal line of the same height on the surface of the wall 8 after construction, according to the height requirements of the junction box. Then, keeping the laser level stationary, when the junction box is clamped and fixed by the junction box fixing mechanism, the bottom edge of the junction box is kept at the same height as the laser horizontal line, thereby achieving uniform calibration of the junction box height.
[0021] Based on the above embodiments, the specific implementation of the plastering mechanism is as follows: The plastering mechanism includes a plastering electric push rod 61, a plastering scraper 62, and a movable sleeve 63. The movable sleeve 63 is slidably sleeved on the outside of the square telescopic sleeve 3. The plastering electric push rod 61 is horizontally fixed on the movable sleeve 63. The plastering scraper 62 is fixedly horizontally at the telescopic end of the plastering electric push rod 61. The plastering electric push rod 61 is perpendicular to the rear masonry wall 8. By utilizing the telescopic movement of the plastering electric push rod 61, the plastering scraper 62 and the surface of the rear masonry wall 8 are brought into contact and separated. A second electric push rod is provided inside the square telescopic sleeve 3. A through groove is vertically provided on the side wall of the square telescopic sleeve 3. One end of a connecting rod is fixedly connected to the movable sleeve 63, and the other end passes through the through groove and is fixedly connected to the telescopic rod end of the second electric push rod. By controlling the telescopic movement of the second electric push rod, the movable sleeve 63 can move up and down outside the square telescopic sleeve 3, thereby driving the plastering scraper 62 to move up and down. The self-locking ability of the second electric push rod is used to position the movable sleeve 63 on the square telescopic sleeve 3. The battery provides power to the plastering electric push rod 61 and the second electric push rod. In practical applications, the mortar scraper 62 is used to smooth the mortar in the wall groove 81. First, the mortar scraper 62 is horizontally and tightly attached to the outside of the wall groove 81. Then, the second electric push rod is activated to slowly move it from top to bottom. As the mortar scraper 62 moves slowly upward, mortar is continuously filled into the wall groove 81 in front of the mortar scraper 62. With the continuous movement of the mortar scraper 62, the mortar in the wall groove 81 is smoothed. In practical applications, to improve the efficiency of manually filling the wall groove 81 corresponding to the mortar scraper 62, a mortar chute 7 is fixedly installed at the upper front end of the telescopic rod of the plastering electric push rod 61. Specifically, the mortar chute 7 is supported by two support rods 72 at the end of the telescopic rod of the plastering electric push rod 61. The mortar chute 7 is fixed in a left-high, right-low configuration. A mortar outlet 71 is located at the bottom right side of the mortar chute 7, above the plastering scraper 62. After mortar is manually filled into the mortar chute 7, the mortar flows continuously towards the mortar outlet 71 under the action of gravity. The mortar flowing out of the mortar outlet 71 is guided by the mortar scraper 62 and enters the wall groove 81 in front of the mortar scraper 62. At the same time, some mortar directly enters the corresponding wall groove 81 from the chute opening on the right side of the mortar chute. This effectively ensures that the wall groove 81 is filled with mortar, thereby ensuring the mortar filling effect in the wall groove 81 and effectively ensuring the quality of mortar smoothing.
[0022] Based on the above embodiments, the specific implementation of the junction box fixing mechanism is as follows: The junction box fixing mechanism includes a junction box electric push rod 51 and a junction box clamping plate 52. The junction box electric push rod 51 is horizontally fixed on the upper part of the right side wall of the square telescopic sleeve 3. The junction box clamping plate 52 is fixed on the end of the telescopic rod of the junction box electric push rod 51. The telescopic movement of the junction box electric push rod 51 realizes the forward and backward movement of the junction box clamping plate 52, thereby allowing the position adjustment of the junction box located on it to conform to the wall groove 81. Burial depth requirements; A clamping groove 521 corresponding to the screw boss inside the wire box is provided on both the front and rear sides of the wire box clamping plate 52. The clamping groove 521 can be locked on the outer wall of the corresponding screw boss. When it is necessary to use the wire box clamping plate 52 to fix the wire box, the wire box clamping plate 52 is inserted into the wire box, and the screw boss inside the wire box is inserted into the corresponding clamping groove 521. By using the two clamping grooves 521 to clamp the corresponding screw boss, the wire box is fixedly installed on the wire box clamping plate 52. The battery provides power to the wire box electric push rod 51.
[0023] Based on the above embodiments, the specific implementation of the conduit fixing mechanism is as follows: The conduit fixing mechanism includes a conduit electric push rod 41 and a conduit arc clamp 42. The two conduit electric push rods 41 are fixedly arranged vertically and horizontally on the right side wall of the square telescopic sleeve 3, and the movable sleeve 63 is located between the two conduit electric push rods 41. A first slide rail 631 is provided on the right side wall of the movable sleeve 63, penetrating both vertically and horizontally. A second slide rail 21 is provided on the upper part of the right side wall of the square fixed sleeve 2, penetrating horizontally and horizontally through the upper side wall of the square fixed sleeve 2. The conduit electric push rod 41 located above can slide within the first slide rail 631. In practical applications, when the movable sleeve 63 moves upward and continuously approaches the conduit electric push rod 41 located above it, after the conduit electric push rod 41 performs a certain retraction movement, the movable sleeve 63 can drive the plastering. The electric push rod 61 moves smoothly above the electric push rod 41 of the conduit, thus facilitating the movement of the sleeve 63 to drive the mortar scraper 62 to move all the way to the bottom of the junction box, thereby effectively expanding the vertical scraping range of the mortar scraper 62. The electric push rod 41 of the conduit located below can slide within the second sliding 21. The conduit arc clamp 42 is fixedly installed at the end of the telescopic rod of the electric push rod 41 of the conduit. The telescopic movement of the electric push rod 41 of the conduit can drive the telescopic movement of the conduit arc clamp 42, thereby using the conduit arc clamp 42 to achieve top pressure fixation of the conduit in the wall groove 81. Using two conduit arc clamps 42 can achieve top pressure fixation of the conduit within a larger vertical range. The electric push rod 41 of the conduit below can enter the second sliding track 21, which facilitates the maximum reduction of the height of the lower conduit arc clamp 42, thereby enabling the lower conduit arc clamp 42 to achieve top pressure fixation of the conduit at a lower position. The battery provides power to the electric push rod of the conduit.
[0024] Based on the above embodiments, the specific implementation of the mobile cart 1 is as follows: The mobile cart 1 includes a support base plate 11, the square fixing sleeve 2 is vertically fixed on the support base plate 11, a push handle 12 located on the left side of the square fixing sleeve 2 is fixed on the support base plate 11, and a universal wheel 13 with brakes is provided at each of the four top corners of the bottom of the support base plate 11. The universal wheel 13 with brakes is used to realize the walking support of the support base plate 11, and the push handle 12 is used to facilitate the mobile cart 1 to flexibly adjust its position and move.
[0025] The process of plastering the wall groove 81 using this utility model is as follows: First, a laser level is used to project the junction box positioning elevation line onto the surface of the back-built wall 8, and then the laser level is kept stationary. Next, the trolley 1 is moved to the front of the wall groove 81 by the push handle 12. Then, the position of the trolley 1 is adjusted so that the square telescopic sleeve 2 is directly aligned with the wall groove 81 and the junction box clamping plate 51, mortar scraper 62, and conduit arc clamp 42 are all within the working range. Then, the universal wheels 13 with brakes are braked to fix the trolley 1. After the trolley 1 is fixed, the first electric push rod is activated to adjust the height of the junction box clamping plate 52. When the height of the junction box clamping plate 52 is aligned with the height of the conduit in the wall groove 81, the trolley 1 is fixed. Once the box height is aligned, the operation of the first electric push rod is stopped. Then, the electric push rod 51 is activated, causing the box clamping plate 52 to continuously approach the box. Through the coordinated action of the first electric push rod and the electric push rod 51, the clamping groove 521 of the box clamping plate 52 can smoothly insert into the screw boss inside the box, thus fixing the box to the box clamping plate 52. After fixing the box, the height of the box is finely adjusted again using the first electric push rod until the bottom of the box is level with the laser level line projected by the laser level. Then, the electric push rod 51 is used to achieve depth positioning of the box within the wall groove 81. After depth positioning, the final positioning of the box is achieved. Finally, the second electric push rod is activated. The first rod moves the mortar scraper 62 to its lowest position. Then, the two electric conduit push rods 41 are activated, causing the conduit arc clamps 42 at their front to press against the conduit in the wall groove 81. Next, the second electric push rod is activated, causing the mortar scraper 62 to slowly and continuously move upwards. As the mortar scraper 62 moves upwards, workers continuously fill the mortar chute 7 with mortar. The mortar in the mortar chute 7 continuously flows into the wall groove 81, and the mortar in the wall groove 81 is smoothed by the action of the mortar scraper 62. As the mortar scraper 62 moves upwards, when it approaches the upper conduit arc clamp 42, the upper electric conduit push rod 41 is activated, causing the upper conduit arc clamp 42 to retract to its initial position. The initial position (at this point, although the positioning of the conduit is released, the mortar already filled below still has a certain limiting effect on the conduit, so releasing the top pressure positioning of the conduit here will not have a significant impact on the displacement of the conduit). When the mortar scraper 62 moves to the highest position, it stops moving and retracts away from the wall. Then, mortar is manually filled around the junction box. After the mortar around the junction box has initially solidified, the junction box electric push rod 51 is activated to make the junction box clamping plate 52 disengage from the junction box and make the lower conduit arc clamp 42 retract away from the wall. After completing the above process, manual plastering is then performed on the areas where plastering cannot be done by this utility model, thereby completing the plastering operation of the entire wall groove 81.
[0026] In this utility model, "front", "rear", "up", "down", "left", and "right" are all relative positions used to facilitate the description of positional relationships, and therefore cannot be understood as absolute positions as a limitation on the scope of protection.

For those skilled in the art, several improvements and modifications can be made without departing from the concept of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
