[0002] Electric power applications can be divided into two categories according to the strength of the power transmission: strong power and weak power. During the construction of weak point projects, pipelines need to be laid, and then the weak current engineering line pipes are laid in the pipelines. However, when laying the pipelines, the engineering line pipes may be squeezed, so the engineering line pipes need to be protected.

[0003] According to a disclosed protective device for wire tubes in weak current engineering projects (Announcement No.: CN217063123U), in the above application, an upper shell, a lower shell, a threaded rod, a connecting block and a protective mechanism are provided. By providing an upper shell and a lower shell on the wire tube body, the wire tube body can be prevented from being squeezed and damaged, and the position of the arc-shaped clamping block can be adjusted by rotating the threaded rod according to the size of the wire tube, so that the wire tube body can be clamped by the arc-shaped clamping block.

[0004] However, in the above application, when clamping the wire tube, the personnel cannot ensure the clamping force. If the personnel does not stop rotating the threaded rod in time, the wire tube may be deformed due to excessive clamping force, thereby affecting the cables inside it. Utility Model Content

[0005] The purpose of the utility model is to provide a protective device for weak current engineering line pipes to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a protective device for weak current engineering line pipe, including a protective cover, the surface of the protective cover is provided with a fixing component and a protective component, the fixing component includes: a threaded rod, a fixing plate, a spring, an arc clamping plate, a sliding rod, and the protective component includes:

[0007] The cam is provided with a groove, and one end of the groove is provided with a groove, and the other end of the groove is provided with a groove, and the groove is connected with the groove to prevent the rotation of the wheel and the threaded rod from being swung.

[0008] Preferably, the threaded rod passes through the protective cover and is threadedly connected to the protective cover. The end of the threaded rod close to the center of the protective cover is rotatably connected to a fixed plate. An arc-shaped clamping plate is fixed to the end of the fixed plate away from the threaded rod. A sliding rod is fixed to the side of the arc-shaped clamping plate close to the fixed plate. The end of the sliding rod away from the arc-shaped clamping plate passes through the fixed plate and the protective cover, and the sliding rod is slidably connected to the fixed plate and the protective cover. The threaded rod is rotated to make the fixed plate and the arc-shaped clamping plate move horizontally through the sliding rod, thereby fixing the wire tube.

[0009] Preferably, the side of the block close to the rotating wheel is set as an inclined surface, and when the inclined surface is resisted, it can enter the sliding groove without affecting the reversal of the rotating wheel and the threaded rod.

[0010] Preferably, two groups of protective covers are provided, and bolts are connected between the two groups of protective covers to facilitate installation and removal of the protective covers.

[0011] Preferably, one side of the fixing plate close to the arc-shaped clamping plate is configured to be arc-shaped, which does not affect the movement of the arc-shaped clamping plate close to the fixing plate.

[0012] Preferably, the card slot is consistent in shape with the card block, making it convenient for the card block to enter the card slot.

[0013] Compared with the prior art, the utility model provides a protective device for weak current engineering line pipes, which has the following beneficial effects:

[0014] 1. The protective device for wire tubes in weak current engineering projects has a protective component. When the arc-shaped clamping plate fits the surface of the wire tube, the threaded rod continues to be rotated to allow the block to enter the slot. When the side of the block away from the inclined surface collides with the inner wall of the slot, the block limits the rotating wheel, so that the threaded rod cannot continue to rotate. This can prevent people from continuously rotating the threaded rod, which may cause excessive clamping force to deform the wire tube. This is convenient for the threaded rod and allows the block to enter the slide groove without affecting the normal reversal of the threaded rod and the rotating wheel.

[0015] 2. The protective device for the wire tube of the weak current engineering project rotates the threaded rod through the set fixing component. At this time, the threaded rod drives the fixing plate to move. At this time, under the action of the sliding rod, the fixing plate drives the arc-shaped clamping plate to move horizontally through the spring. At this time, the surface of the arc-shaped clamping plate contacts the wire tube, which can clamp and fix the wire tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a protective device for a weak current engineering line pipe, including a protective cover 1, the surface of the protective cover 1 is provided with a fixing component 3 and a protective component 4, the fixing component 3 includes: a threaded rod 30, a fixing plate 31, a spring 1 32, an arc-shaped clamping plate 33, and a sliding rod 34, and the protective component 4 includes: a rotating wheel 40, a slot 41, a movable rod 42, a through hole 43, a slider 44, a slide groove 45, a block 46, and a spring 2 47.

[0023] The rotating wheel 40 is rotatably connected to the side of the fixed plate 31 close to the protective cover 1, a groove 41 is provided on the surface of the rotating wheel 40, a movable rod 42 is hinged on the side of the arc-shaped clamping plate 33 close to the fixed plate 31, a through hole 43 is provided on the surface of the fixed plate 31, the movable rod 42 is away from the through hole 43 of the arc-shaped clamping plate 33, a slider 44 is slidably connected to the side of the fixed plate 31 away from the arc-shaped clamping plate 33, a sliding groove 45 is provided on the side of the slider 44 close to the rotating wheel 40, a block 46 is slidably connected to the inner wall of the sliding groove 45, a spring 2 47 is fixed on the surface of the block 46, one end of the spring 2 47 away from the block 46 is fixed on the inner wall of the sliding groove 45, the movable rod 42 is away from the arc-shaped clamping plate 33 One end is hinged to a side of a slider 44 close to the arc-shaped clamping plate 33, and the rotating wheel 40 is penetrated by the threaded rod 30, and the rotating wheel 40 is fixedly connected to the threaded rod 30. When the arc-shaped clamping plate 33 is in contact with the surface of the wire tube, the threaded rod 30 continues to be rotated, and the fixed plate 31 continues to move. The movable rod 42 drives the slider 44 and the block 46 to move close to the rotating wheel 40, so that the block 46 enters the slot 41. When the side of the block 46 away from the inclined surface contacts the inner wall of the slot 41, the block 46 limits the rotating wheel 40, so that the threaded rod 30 cannot continue to rotate, which can prevent people from continuously rotating the threaded rod 30, thereby preventing the clamping force from being too large and causing the wire tube to deform.

[0024] The threaded rod 30 passes through the protective cover 1, and the threaded rod 30 is threadedly connected to the protective cover 1. The end of the threaded rod 30 close to the center of the protective cover 1 is rotatably connected to the fixed plate 31, and the end of the fixed plate 31 away from the threaded rod 30 is fixed with an arc-shaped clamping plate 33, and a sliding rod 34 is fixed on the side of the arc-shaped clamping plate 33 close to the fixed plate 31. The end of the sliding rod 34 away from the arc-shaped clamping plate 33 passes through the fixed plate 31 and the protective cover 1, and the sliding rod 34 is slidably connected to the fixed plate 31 and the protective cover 1, and the wire tube is passed between the two groups of protective covers 1. At this time, the personnel can rotate the threaded rod 30, and the threaded rod 30 drives the fixed plate 31 to move. At this time, under the action of the sliding rod 34, the fixed plate 31 drives the arc-shaped clamping plate 33 to move horizontally through the spring 32. At this time, the surface of the arc-shaped clamping plate 33 contacts the wire tube, thereby clamping and fixing it.

[0025] The side of the block 46 close to the rotating wheel 40 is set as an inclined surface. When the inclined surface is resisted, the block 46 can enter the slide groove 45.

The side of the fixed plate 31 close to the arc-shaped clamping plate 33 is set to an arc shape, which will not affect the movement of the arc-shaped clamping plate 33 close to the fixed plate 31. The shape of the slot 41 is consistent with that of the block 46, which is convenient for the block 46 to enter.

[0026] When in use, the wire tube is passed between the two sets of protective covers 1. At this time, the person can rotate the threaded rod 30, and the threaded rod 30 drives the fixed plate 31 to move. At this time, under the action of the sliding rod 34, the fixed plate 31 drives the arc clamping plate 33 to move horizontally through the spring 1 32. At this time, the surface of the arc clamping plate 33 contacts the wire tube. At this time, the person continues to rotate the threaded rod 30, and the fixed plate 31 continues to move, so that the movable rod 42 is offset at an angle, thereby driving the slider 44 and the block 46 to move close to the rotating wheel 40, so that the block 46 enters the slot 41. When the side of the block 46 away from the inclined surface contacts the inner wall of the slot 41 At this time, the block 46 limits the rotating wheel 40, so that the threaded rod 30 cannot continue to rotate, which can prevent the person from continuously rotating the threaded rod 30, thereby causing the clamping force to be too large to cause the wire tube to deform. When the wire tube needs to be taken out, the person can reverse the threaded rod 30. At this time, the rotating wheel 40 reverses so that the inner wall of the clamping groove 41 contacts the inclined surface of the block 46, so that the block 46 enters the slide groove 45, which will not affect the normal reversal of the rotating wheel 40 and the threaded rod 30. At this time, the person can take out the wire tube. At the same time, through the bolt 2, it is convenient for the person to install or disassemble the protective cover 1. The protective cover 1 can protect the wire tube and prevent external force from hitting the wire tube.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
