Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft nuts, in particular to an anti-theft nut for an electric power tower. Background Art

[0002] Some power towers are installed in remote areas in the wild and cannot be well managed. Some lawless elements steal the steel of the towers and sell them. This will not only cause economic losses to the national power department, but also easily cause electric shock accidents. Therefore, anti-theft nuts are used.

[0003] The currently used anti-theft nuts are all improved in the thread profile, and some relatively complex threads are designed, which makes the nut production process relatively complicated and costly, and is not suitable for large-scale use. For this reason, the utility model provides a new type of power tower anti-theft nut. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an anti-theft nut for an electric power tower.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An anti-theft nut for an electric power tower comprises: a gasket structure and a nut structure;

[0007] The gasket structure comprises a washer, the outer edge of which extends toward the direction where the nut structure is located to form an annular sleeve, and the nut structure is located on the inner side of the annular sleeve.

[0008] As a further description of the above technical solution:

[0009] The nut structure comprises: a nut body, wherein a friction wedge is arranged at one end of the nut body away from the washer, and there are a plurality of friction wedges, which are distributed in a ring array.

[0010] As a further description of the above technical solution:

[0011] The inner side of the annular sleeve is fixedly connected with a structural block.

[0012] As a further description of the above technical solution:

[0013] The length of the annular sleeve is greater than the length of the nut structure.

[0014] As a further description of the above technical solution:

[0015] The number of the structural blocks is six, and the six structural blocks are distributed in a ring array.

[0016] As a further description of the above technical solution:

[0017] The wall thickness of the annular sleeve is not less than 2MM.

[0018] The utility model has the following beneficial effects:

[0019] Compared with the prior art, this anti-theft nut for an electric tower improves the gasket structure to form an annular sleeve. After the nut structure is installed and tightened, the nut structure is located on the inner side of the annular sleeve, making it impossible to use a wrench to remove the nut structure, thereby playing an anti-theft role. The gasket structure in this structure can be stamped, with low manufacturing cost, and can be widely put into use.

[0020] Compared with the prior art, this electric tower anti-theft nut is provided with a friction wedge at one end of the nut body away from the washer. Multiple friction wedges are distributed in a ring array to form a friction surface that can transmit rotation in one direction, so as to facilitate driving the nut body from the end to tighten and install it.

[0028] Reference Figure 1-Figure 2 The utility model provides an anti-theft nut for an electric power tower, comprising: a gasket structure 1 and a nut structure 2.

[0029] Among them, the gasket structure 1 includes a gasket 101, the outer edge of the gasket 101 extends toward the direction of the nut structure 2 to form an annular sleeve 102, the nut structure 2 is located on the inner side of the annular sleeve 102, the outer side of the annular sleeve 102 is circular, and the nut structure 2 completely enters the annular sleeve 102, so that the nut structure 2 cannot be removed by using a wrench, thereby playing an anti-theft role. In this structure, the gasket structure 1 can be stamped (that is, the gasket 101 and the annular sleeve 102 are integrally formed), with low manufacturing cost, and can be widely put into use.

[0030] In one embodiment, the nut structure 2 includes: a nut body 201, a friction wedge 202 is provided at one end of the nut body 201 away from the washer 101, there are multiple friction wedges 202, and the multiple friction wedges 202 are distributed in a ring array, and the multiple friction wedges 202 constitute a friction surface that can transmit rotation in one direction, so as to facilitate driving the nut body 201 from the end to tighten and install it.

[0031] A structural block 103 is fixedly connected to the inner side of the annular sleeve 102, so that the gasket structure 1 is not easily deformed, and the annular sleeve 102 is avoided from being squeezed, so that the annular sleeve 102 is tightly attached to the nut body 201, and the annular sleeve 102 has a hexagonal shape. A wrench is clamped on the outer side of the annular sleeve 102, and the annular sleeve 102 and the nut body 201 are rotated synchronously to disassemble the nut structure 2.

[0032] The wall thickness of the annular sleeve 102 is not less than 2 MM, and its purpose is also to prevent the gasket structure 1 from being easily deformed, so as to avoid the use of the same means as mentioned above to disassemble the nut structure 2.

[0033] The length of the annular sleeve 102 is greater than the length of the nut structure 2 , so that the nut structure 2 can completely enter the interior of the annular sleeve 102 .

[0034] The number of the structural blocks 103 is six, and the six structural blocks 103 are distributed in a ring array. The six structural blocks 103 correspond to the six side surfaces of the nut body 201 .

[0035] like Figure 3 As shown in the figure, a usage scenario of anti-theft nuts for power towers is that a screw 5 is fixed and welded on the side of an I-beam 3 (a component of the power tower), a through hole is opened on the side of a pole frame 4 (a component of the power tower), the through hole of the pole frame 4 is sleeved on the screw 5, and then a gasket structure 1 and a nut structure 2 are installed on the screw 5.

[0036] like Figure 4 , Figure 5 As shown, it is a schematic diagram of the installation of the anti-theft nut of the power tower. When installing the anti-theft nut of the power tower, an auxiliary tool is required, and the auxiliary tool is driven by a wrench, and the auxiliary tool drives the nut structure 2 to rotate from the end of the nut structure 2.

[0037] The auxiliary tools include: a tightening piece 6 and a pressing sleeve 7.

[0038] Among them, the tightening part 6 includes: an annular part 601, an inner ring part 602, a hexagonal part 604 and a tooth boot 603, which is fixedly connected to the first end of the annular part 601, the tooth boot 603 is fixedly set at the second end of the annular part 601, and the hexagonal part 604 is fixedly set on the outer side of the annular part 601. The wrench can be clamped in the hexagonal part 604 to rotate the tightening part 6.

[0039] The pressing sleeve 7 includes: a nut 701 and a rod 702 . The nut 701 is threadedly matched with the screw rod 5 . One end of the rod 702 is fixedly connected to the outer side of the nut 701 , and the rod 702 is along the radial direction of the nut 701 .

[0040] When installing the anti-theft nut of the power tower, it is necessary to first put the gasket structure 1 on the screw rod 5, and then use a wrench to rotate the nut structure 2. When the nut structure 2 basically enters the annular sleeve 102 of the gasket structure 1, the wrench can no longer be stuck on the nut structure 2. At this time, one end of the tightening member 6 with the tooth boot 603 is put on the screw rod 5, and then the nut member 701 is threadedly installed on the screw rod 5. The nut member 701 can be easily manipulated to rotate through the rod body 702, so that the tooth boot 603 of the tightening member 6 is against the friction wedge 202. Then the user uses a wrench to get stuck at the hexagonal part 604 to rotate the tightening member 6. The tooth boot 603 can drive the friction wedge 202, and then drive the nut body 201 to rotate. The position of the nut member 701 can be repeatedly adjusted appropriately to make the tooth boot 603 and the friction wedge 202 close to each other, and finally complete the tightening operation of the nut structure 2.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
