Technical Field
The utility model relates to a wire rod waterproof equipment technical field, more specifically relate to a wire rod passes waterproof construction of shell.
Background
In waterproof products requiring an output wire, it is difficult to waterproof the outlet wire. Conventional breach embedding mode, convenient dismantlement, but waterproof grade is difficult to do height and unstable, can receive material precision and production technology influence great. When high-grade water proofing is needed, the joint of the wire and the shell needs to be fixed by sealant, so that the wire and the shell are difficult to disassemble, and the reliability is also influenced by a gluing process.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: in order to solve the problem that present output line waterproof product leakproofness is not good and not convenient to detach, the utility model provides a wire rod passes the waterproof construction of shell.
The utility model discloses a realize above-mentioned purpose and specifically adopt following technical scheme:
a waterproof structure for a wire to penetrate through a shell comprises a shell and an output line, wherein a circular hole is formed in one side of the shell, an adhesive covering head is arranged on the output line in a surrounding mode and penetrates through the circular hole, an annular first concave position is formed in the position, on the adhesive covering head, of the outer portion of the shell and is provided with a first concave position, an O-shaped ring is sleeved on the first concave position, the O-shaped ring is tightly matched with the circular hole, and a tensioning assembly for preventing the adhesive covering head from being pulled out is arranged inside the shell.
Furthermore, the tensioning assembly comprises an annular second concave position arranged on the rubber coating head, the second concave position is located inside the shell, the minimum distance between the first concave position and the second concave position is smaller than the length of the circular hole, the tensioning assembly further comprises a retaining ring matched with the second concave position, and the retaining ring is sleeved on the second concave position.
Furthermore, the O-shaped ring is made of elastic rubber.
Further, the bottom of the retainer ring is provided with an opening.
The working principle is as follows: during the use, cover on first concave position and penetrate O shape circle, inject the circular hole site with the rubber coating head, insert the retaining ring on the second concave position, can accomplish the installation, when dismantling, only need with the retaining ring take down can.
The utility model has the advantages as follows:
1. the utility model discloses simple structure, convenient to use glues the circular hole site lateral wall cooperation of lateral wall, O type circle and the shell of the first concave position of head through the package, makes O shape circle warp through taut subassembly and realizes waterproof purpose, so waterproof reliability only is relevant with three's size precision, as long as the three does not take place to break away from just can be reliable realization high-grade waterproof.
2. The utility model discloses simple structure, convenient to use is through setting up the concave position of second to the retaining ring is established to the cover on the concave position of second, thereby realizes the head is glued to the packing of tensioning, makes O shape circle warp, thereby reaches waterproof purpose, when the installation, inserts the overhead gage, when dismantling, takes off the baffle, consequently the convenience very when installation and dismantlement.
Drawings
FIG. 1 is an assembly view of the present invention;
fig. 2 is a schematic view of the connection structure of the present invention.
Reference numerals: 101-output line, 102-rubber-coated head, 103-O-shaped ring, 104-retainer ring, 201-shell.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
Please refer to fig. 1-2, the utility model provides a wire rod passes waterproof construction of shell, including shell 201 and output line 101, circular hole site has been seted up to one side of shell 201, it is provided with rubber coating head 102 to surround on output line 101, rubber coating head 102 passes circular hole site, it has seted up annular first concave position to lie in shell 201 outside on rubber coating head 102, the cover is equipped with O shape circle 103 on the first concave position, O shape circle 103 closely cooperates with circular hole site, the inside of shell 201 is provided with the taut subassembly that prevents rubber coating head 102 and pull out.
In this embodiment, the O-ring 103 is made of an elastic rubber material.
Through the cooperation of the side wall of the first concave position of the rubber coating head 102, the O-shaped ring 103 and the side wall of the circular hole position of the shell 201, the O-shaped ring 103 is deformed by the tensioning assembly to achieve the waterproof purpose, so the waterproof reliability is only related to the dimensional accuracy of the three, and high-grade waterproof can be reliably achieved as long as the three are not separated.
Example 2
Referring to fig. 1-2, the present invention is further improved on the basis of embodiment 1, specifically, the tightening assembly includes an annular second concave position provided on the rubber covering head 102, the second concave position is located inside the housing 201, the minimum distance between the first concave position and the second concave position is smaller than the length of the circular hole, the tightening assembly further includes a retaining ring 104 adapted to the second concave position, and the retaining ring 104 is sleeved on the second concave position.
In this embodiment, the O-ring 103 is made of an elastic rubber material.
Through setting up the concave position of second to retaining ring 104 is established to the cover on the concave position of second, thereby realizes straining rubber-covered head 102, makes O shape circle 103 warp, thereby reaches waterproof purpose, when the installation, inserts retaining ring 104, when dismantling, takes off retaining ring 104, therefore very convenience when installation and dismantlement.
