DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1-Figure 7 As shown, a building electrical wiring construction auxiliary device includes a shell 1, a cross rod 2, a climbing assembly 3 and a driving assembly 4. The cross rod 2 includes two cross-mounted straight rods 21, and the middle parts of the two straight rods 21 are rotatably connected through a spring shaft 22. One end of the cross rod 2 is connected to the climbing assembly 3 through the spring shaft 22. The climbing assembly 3 includes a climbing claw 31 for grasping the pipe wall of the wire tube and moving forward. A rotating shaft 32 is fixed to the surface of the climbing claw 31, and the rotating shaft 32 is sleeved on the inner wall of a traction ring sleeve 33. The traction ring sleeve 33 is connected to a climbing rope 34. The other end of the cross rod 2 is fixed to a connecting shaft 23, and the driving assembly 4 is installed through the connecting shaft 23. The driving assembly 4 is used to drive the two straight rods 21 to rotate around the spring shaft 22 at the intersection in the middle.

[0026] The structure squeezes the wire tube wall on both sides through the climbing claw 31, and drives the device to run inside the tube wall through friction. The specific operation method is to insert the device into the wire tube, rotate the straight rod 21 in the cross rod 2 through the driving component 4, and through the lever principle, when one end of the two straight rods 21 approaches each other, the other end will also approach each other, and will move forward relative to the initial position, and the climbing claw 31 will also move to a position more forward than the initial position; the climbing claw 31 is pulled by the climbing rope 34 to change the connection angle between it and the straight rod 21, so that the climbing claw 31 can resist the tube wall on both sides, and then the climbing rope 34 is released, and the spring shaft 22 between the climbing claw 31 and the straight rod 21 is used to make the connection angle between the climbing claw 31 and the straight rod 21 return to the original position, and drive the device to run forward. The spring shaft 22 in the structure is an automatic reset shaft equipped with a spring, and its spring material is preferably stainless steel, carbon steel and alloy steel with high strength, corrosion resistance and good elasticity; the automatic reset spring shaft 22 is usually designed as a spiral or torsion bar shape, and the parameters such as the number of turns, diameter and wire diameter of the spiral spring determine its torque and reset force. The torsion bar spring achieves different torques and reset forces by changing its cross-sectional shape and length. In order to obtain the required reset force, the spring shaft 22 will be preloaded during the production process. The spring has a certain torque when it leaves the factory. When an external force acts, the torque will be released or increased, thereby realizing the automatic reset function; the spring shaft 22 needs to be correctly installed and fixed in the equipment or device to ensure that it can work normally and withstand the required torque and load, and ensure that it can provide a reliable automatic reset function. In this structure, the clockwork spring shaft 22 is used at the intersection of the straight rod 21 and at the connection between the straight rod 21 and the climbing claw 31, so that when the intersection angle of the straight rod 21 is changed or the connection angle between the climbing claw 31 and the straight rod 21 is changed, a corresponding automatic reset effect is provided, so that the structure can realize repeated forward movement.

[0027] like Figure 2-Figure 4 As shown, the driving assembly 4 includes two brake rods 41 , both ends of the brake rods 41 are provided with shaft holes, and the shaft hole at one end is adapted to the connecting shaft rod 23 on the straight rod 21 .

[0028] The brake rod 41 is rotatably connected to the connecting shaft 23 on the straight rod 21 through the shaft hole, so that the brake rod 41 can change the crossing angle between the two straight rods 21 by changing the angle between the brake rod 41 and the straight rod 21, thereby changing the position of the climbing claw 31 connected to the other end of the straight rod 21.

[0029] like Figure 1-Figure 2As shown, the housing 1 includes an upper cover 11 and a bottom cover 12, and the upper cover 11 and the bottom cover 12 are adapted to each other. The surfaces of the upper cover 11 and the bottom cover 12 are provided with corresponding transverse grooves 13, and both ends of the connecting shaft 23 are sleeved with sliding rings 24, and the connecting shaft 23 forms a sliding structure with the transverse grooves 13 through the sliding rings 24.

[0030] When the connecting shaft 23 slides in the transverse groove 13 on the housing 1 through the sliding ring 24, when the brake rod 41 changes the connection angle between it and the straight rod 21, the intersection angle between the two straight rods 21 will also be displaced, and the distance between the ends of the two straight rods 21 will also change accordingly. The transverse groove 13 can limit the displacement of the ends of the straight rods 21 to occur only along the inside of the transverse groove 13, and through this displacement, the forward and backward movement of the intersection of the two straight rods 21 is controlled.

[0031] like Figure 2-Figure 4 As shown, a through-shaft ring 42 is arranged on the outer side of one end of the two brake rods 41 that are rotatably connected, and the brake rod 41 is connected to one end of a brake cable 43 through the through-shaft ring 42 .

[0032] One end of the brake cable 43 is connected to a shaft rod, and the shaft rod is rotatably connected to the through-shaft ring 42. The directions of the brake cable and the climbing cable 34 are consistent, and both are preferably made of tough steel wire as the main material. The brake cable 43 and the climbing cable 34 are almost the same in length. The brake cable 43 is used to control the position and connection angle of the two brake rods 41, and the climbing cable 34 is used to control the connection angle between the climbing claw 31 and the straight rod 21; by pulling the brake cable 43 and the climbing cable 34 alternately, the climbing claw 31 can repeatedly extend forward, turn to resist the pipe wall, and drive the device to reset through the spring shaft rod 22, so as to achieve the effect of pushing the device forward.

[0033] like Figure 1-Figure 2 As shown, the surfaces of the upper cover 11 and the bottom cover 12 are further provided with an upper longitudinal groove 14 and a lower longitudinal groove 15, and the upper longitudinal groove 14 and the lower longitudinal groove 15 are symmetrically distributed about the transverse groove 13, and the ends of the two brake rods 41 away from the straight rod 21 are rotationally connected with the shaft rod through the shaft hole, and the two ends of the shaft rod form a sliding structure with the lower longitudinal groove 15 through the sliding ring sleeve 24, and the two ends of the clockwork spring shaft rod 22 at the intersection of the two straight rods 21 form a sliding structure with the upper longitudinal groove 14 through the sleeved sliding ring sleeve 24.

[0034] When the brake cable 43 is pulled backward, the brake cable 43 moves the two brake rods 41 along the direction of the lower longitudinal groove 15 through the shaft ring 42, and the connection between the brake rod 41 and one end of the straight rod 21 moves closer to each other along the transverse groove 13, and at the same time, the spring shaft 22 at the intersection of the straight rod 21 moves forward along the upper longitudinal axis, thereby causing the climbing claws 31 at one end of the straight rod 21 to move closer to each other and move forward, providing the prerequisite for the subsequent rotation and climbing of the climbing claws 31.

[0035] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, positioners 5 are installed on both sides of the bottom cover 12 for limiting and fixing the outer shell 1 and the inner wall of the wire tube. The positioner 5 includes a connecting seat 51, and the connecting seat 51 is fixedly connected to both sides of the bottom cover 12. One end of the connecting seat 51 is sleeved with an extrusion spring 52, and one end of the extrusion spring 52 is connected to a movable shaft seat 53. The movable shaft seat 53 forms an elastic structure with the connecting seat 51 through the extrusion spring 52. A semicircular shaft head 54 is installed at one end of the movable shaft seat 53, and a rotating structure is formed between the semicircular shaft head 54 and the movable shaft seat 53.

[0036] When the climbing claws 31 are close to each other, they break contact with the wall of the wire tube, so that the device breaks the fixed limit with the wall of the wire tube. At this time, the positioner 5 provides a limiting effect between the shell 1 and the wall of the wire tube, and the squeezing spring 52 makes the semicircular shaft head 54 press against the wall of the wire tube. Since the semicircular shaft head 54 can only rotate backward around one end of the movable shaft seat 53 but cannot rotate forward, when the semicircular shaft head 54 presses against the wall of the wire tube, the entire device will not slide backward; when the climbing claw 31 performs a reset action to drive the entire device to move forward, similarly, since the semicircular shaft head 54 can rotate backward around one end of the movable shaft seat 53, it will not affect the climbing claw 31 to drive the entire device to move forward.

[0037] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
