[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

[0031] It should be noted that the connection component 102 and the sleeve component 101 can be integrally cast or connected by welding, and the connection component 102 and the clamping component 104 can be connected by socketing, which can greatly facilitate the assembly of the connection component 102 and the clamping component 104.

[0032] When in use, first squeeze the clamping assembly 104 to open it, then insert the low-voltage meter line end into the bushing assembly 101 , and then loosen the clamping assembly 104 , so that the clamping assembly 104 is reset under the action of the reset assembly 103 .

[0033] In summary, the beneficial effect of an insulating head cover device for the end of a low-voltage meter line is that the clamping component 104 can clamp the low-voltage meter line, thereby preventing the sleeve component 101 from falling off the low-voltage meter line during use, thereby increasing safety. At the same time, the setting of the reset component 103 enables the clamping component 104 to achieve automatic reset and provide a certain pressure to ensure the stability of the clamping component 104.

[0034] Example 2

[0035] Reference Figure 3 , which is the second embodiment of the present invention, provides a low-voltage electric meter line end insulating head cover device, which includes a protection unit 100, the protection unit 100 includes a sleeve assembly 101, a group of connecting assemblies 102 arranged on the outside of the sleeve assembly 101, a reset assembly 103 arranged on the outside of the connecting assembly 102, and a clamping assembly 104 arranged on the outside of the connecting assembly 102.

[0036] It should be noted that the connection component 102 and the sleeve component 101 can be integrally cast or connected by welding, and the connection component 102 and the clamping component 104 can be connected by socketing, which can greatly facilitate the assembly of the connection component 102 and the clamping component 104.

[0037] Furthermore, the sleeve assembly 101 includes an insulating tube 101a, a limiting hole 101b is provided at one end of the insulating tube 101a, and an anti-slip stripe 101c is arranged on the outer side of the insulating tube 101a.

[0038] Furthermore, the connection assembly 102 includes two groups of limiting rods 102a arranged outside the insulating tube 101a, a through hole 102b arranged on one side of the limiting rod 102a, and a fixing rod 102c penetrating the inside of the through hole 102b.

[0039] Furthermore, the reset assembly 103 includes a torsion spring 103a disposed outside the fixing rod 102c, and extension rods 103b disposed at both ends of the torsion spring 103a.

[0040] Furthermore, the clamping assembly 104 includes a pressing plate 104a, a group of arc blocks 104b arranged on one side of the pressing plate 104a, a second through hole 104c is opened on one side of the arc block 104b, and the arc block 104b is arranged outside the fixing rod 102c.

[0041] Preferably, the setting of the insulating tube 101a can be conveniently put on the end of the low-voltage meter line, which can avoid electric shock and facilitate the disassembly of the low-voltage meter. At the same time, the setting of the anti-slip stripes 101c can improve the grip of the insulating tube 101a and avoid slipping during use. The setting of the limiting rod 102a and the fixing rod 102c facilitates the installation and limiting of the pressure plate 104a. At the same time, the setting of the pressure plate 104a can have a clamping effect on the line, further ensuring the stability of the insulating tube 101a at the line end. The torsion spring 103a and the extension rod 103b can automatically reset the pressure plate 104a, and at the same time, it can also ensure that the pressure plate 104a is always close to the outer wall of the low-voltage meter line, thereby achieving a clamping effect.

[0042] Furthermore, the diameter of the insulating tube 101a gradually shortens from top to bottom along the central axis, and the anti-slip stripes 101c are distributed in a ring shape on the outer side of the insulating tube 101a with the central axis as the center.

[0043] It should be noted that the diameter of the insulating tube 101a is gradually shortened from top to bottom along the central axis, so that it can cope with low-voltage meter wires of various specifications and improve the practicality of the insulating tube 101a.

[0044] Furthermore, a group of pressing plates 104a are provided, and the pressing plates 104a are symmetrically arranged, and one end of the pressing plate 104a is arranged to be an inwardly concave arc shape.

[0045] It should be noted that one side of the pressing plate 104a is provided with an inwardly concave arc, so that one end of the pressing plate 104a can better fit on the outside of the low-voltage electric meter line.

[0046] Furthermore, a group of pressing plates 104a are provided, and the pressing plates 104a are symmetrically arranged, and one end of the pressing plate 104a is arranged to be an inwardly concave arc shape.

[0047] Furthermore, the arc block 104b is sleeved on the outside of the fixing rod 102c, and the fixing rod 102c passes through the second through hole 104c.

[0048] Furthermore, one of the extension rods 103b provided at both ends of the torsion spring 103a is attached to one side of the pressing plate 104a, and the other of the extension rods 103b provided at both ends of the torsion spring 103a is attached to the outside of the insulating tube 101a.

[0049] When in use, first squeeze the pressing plate 104a inward, and the inner wall of the pressing plate 104a squeezes the extension rod 103b. The extension rod 103b moves inward with the cooperation of the torsion spring 103a, so that one end of the pressing plate 104a is opened, and the end of the low-voltage meter line is further inserted into the insulating tube 101a, and the squeezing of the pressing plate 104a is further released. The pressing plate 104a is pushed by the cooperation of the torsion spring 103a and the extension rod 103b to move away from the insulating tube 101a, and the other end of the pressing plate 104a approaches the outside of the low-voltage meter line until the concave arc opened at one end of the pressing plate 104a fits against the outside of the low-voltage meter line.

[0050] In summary, the beneficial effect of an insulating head cover device for the end of a low-voltage meter line is that the clamping component 104 can clamp the low-voltage meter line, thereby preventing the sleeve component 101 from falling off the low-voltage meter line during use, thereby increasing safety. At the same time, the setting of the reset component 103 enables the clamping component 104 to achieve automatic reset and provide a certain pressure to ensure the stability of the clamping component 104.

[0053] It should be noted that the pressure plate 104a is first squeezed inward, and the inner wall of the pressure plate 104a squeezes the extension rod 103b. The extension rod 103b moves inward with the cooperation of the torsion spring 103a, so that one end of the pressure plate 104a is opened, and the end of the low-voltage meter line is further inserted into the insulating tube 101a, and the squeezing of the pressure plate 104a is further released. The pressure plate 104a is pushed by the cooperation of the torsion spring 103a and the extension rod 103b to move away from the insulating tube 101a, and the other end of the pressure plate 104a approaches the outside of the low-voltage meter line until the concave arc opened at one end of the pressure plate 104a fits against the outside of the low-voltage meter line.

[0054] In summary, the beneficial effect of the insulating head cover device at the end of a low-voltage meter line is that the clamping component 104 can clamp the low-voltage meter line, thereby preventing the sleeve component 101 from falling off the low-voltage meter line during use, thereby increasing safety. At the same time, the setting of the reset component 103 enables the clamping component 104 to achieve automatic reset and provide a certain pressure to ensure the stability of the clamping component 104.
