Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention. The invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
As shown in fig. 1 and 2, the invention provides a power line sealing tool 10, which comprises a power line 11 and a line bolt 12.
The wire passing bolt 12 comprises a bolt rod body 121 and a bolt head 122, wherein the bolt rod body 121 is cylindrical, a thread 121b is formed on the outer side surface of one end of the bolt rod body 121, a wire passing hole 121a is formed in the bolt rod body 121 along the length direction of the bolt rod body, the bolt head 122 is fixedly connected to one end, far away from the thread 121b, of the bolt rod body 121, a stepped hole 122a is formed in the bolt head 122, the stepped hole 122a is communicated with the wire passing hole 121a, and the cross-sectional area of the stepped hole 122a is larger than that of the wire passing hole. The power line 11 sequentially penetrates through the line passing hole 121a and the stepped hole 122a, and the outer side wall of the power line 11 is in clearance fit with the inner side wall of the line passing hole 121 a. Waterproof sealant 1221 is filled in the stepped hole 122a, and when the stepped hole is solidified, a gap between the power line 11 and the wire passing hole 121a is filled along the surface of the power line 11, so that effective sealing of the circumferential surface is realized.
In this embodiment, the stepped hole 122a and the wire passing hole 121a are both cylindrical holes, and the stepped hole 122a and the wire passing hole 121a are coaxially communicated, so as to facilitate the penetration of the power wire 11; preferably, the diameter of the stepped hole 122a is 2-3 times the diameter of the wire through hole 121a, for example, in the present embodiment, the diameter of the stepped hole 122a is 2.4 times the diameter of the wire through hole 121 a.
An annular step surface 122b is formed at one end, close to the bolt rod body 121, of the bolt head 122 along the circumferential direction of the bolt rod body 121, a sealing ring clamping groove 122c is formed in the annular step surface 122b, and a sealing ring 123 can be installed in the sealing ring clamping groove 122c so that when the bolt is screwed down, the sealing ring 123 is compressed to deform and further realize effective sealing of the end surface. The surface of the sealing ring 123 is coated with vaseline, and the vaseline coated on the sealing ring 123 can provide a lubricating effect for the sealing ring 123, so that the abrasion of the sealing ring 123 is effectively reduced.
Further, two wrench clamping notches D1 and D2 are formed in the side surface of the bolt head 122, and the two wrench clamping notches D1 and D2 are symmetrically arranged on two sides of one end of the bolt head 122 away from the bolt rod body 121; a limit step 122D is formed between the wrench locking notches D1, D2 and the bolt head 122. Two spanner chucking breach D1, D2 can cooperate the spanner to make to connect reliable and stable with the effective tightening of line bolt 12, prevent that control storehouse or battery compartment from intaking, and wherein spacing step 122D can effectively guarantee that the spanner can not slide to bolt body of rod 121 one side when the joint is on bolt head 122, have ensured the connection reliability of spanner and bolt head.
The outer side wall of the bolt head 122 except the two wrench clamping notches D1 and D2 is formed with an anti-slip knurl 122e, and the anti-slip knurl 122e on the bolt head 122 is convenient for an operator to pre-tighten the thread-passing bolt 12 by hand.
When the power line sealing tool 10 provided by the embodiment of the invention is used, one end of the wire passing bolt 12 with threads is installed on the control bin or the battery bin, the sealing ring 123 is attached to the surface of the control bin or the battery bin, and when the wire passing bolt 12 is screwed down, the sealing ring 123 is compressed to generate deformation, so that effective sealing of the peripheral surface is realized, meanwhile, the sealing ring clamping groove 122b limits the displacement of the sealing ring 123, and the phenomenon that the sealing ring 123 falls off to cause the water inlet short circuit of a robot is prevented; secondly, the waterproof sealant 1221 filled in the stepped hole 122a fills a gap between the power line 11 and the wire passing hole 121a along the surface of the power line 11 when being solidified, so as to realize effective sealing of the end face.
The foregoing is merely a preferred embodiment of the invention and is not intended to limit the invention in any manner; the present invention may be readily implemented by those of ordinary skill in the art as illustrated in the accompanying drawings and described above; however, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the scope of the invention as defined by the appended claims; meanwhile, any changes, modifications, and evolutions of the equivalent changes of the above embodiments according to the actual techniques of the present invention are still within the protection scope of the technical solution of the present invention.
