Abstract
The utility model discloses a kind of latch assembly, described latch assembly is formed by latch arm and bolt axle cooperation, described latch arm comprises main body, arranges the first hole on the body and the second hole, described bolt axle comprises axis body, is arranged on the multidiameter shaft of described axis body one end, and be arranged on the tapered portion of described axis body the other end, the diameter in described first hole is identical with the diameter of described multidiameter shaft, and described multidiameter shaft coordinates with described first hole.The superior effect of the utility model latch assembly is: the latch arm of latch assembly is provided with first hole identical with multidiameter shaft diameter, before welding latch arm and bolt axle, multidiameter shaft coordinates with the first hole thus keeps latch arm and bolt axle to arrange in 90 ° between the two, then uses welding machine to burn-on in the first hole and multidiameter shaft cooperation circular contour place weld part.The structure of latch assembly is simple, convenient and practical, has good market application foreground.
Description
Technical field
The utility model belongs to latch technical field of tools, is specifically related to a kind of latch assembly.
Background technique
Existing latch arm and bolt axle by being welded and fixed, and need to keep the angle between latch arm and bolt axle to be 90 °.But before welding, be by manually gripping latch arm and bolt axle, then use welding machine in both joint welding.When welding, artificial gripping easily causes latch arm and bolt axle to rock, and causes bolt axle to occur tilting, and is difficult to the perpendicularity after being welded and fixed both ensureing.
Model utility content
The utility model provides a kind of latch assembly, to solve existing latch arm and bolt axle by being welded and fixed, is difficult to the technological deficiency ensureing perpendicularity between the two.
In order to solve above technical problem, the technological scheme that the utility model is taked is:
A kind of latch assembly, described latch assembly is formed by latch arm and bolt axle cooperation, described latch arm comprises main body, arranges the first hole on the body and the second hole, described bolt axle comprises axis body, is arranged on the multidiameter shaft of described axis body one end, and be arranged on the tapered portion of described axis body the other end, the diameter in described first hole is identical with the diameter of described multidiameter shaft, and described multidiameter shaft coordinates with described first hole.
Be preferably, the diameter in described first hole is greater than the diameter in described second hole.
Be preferably, the diameter of described multidiameter shaft is less than the diameter of described axis body.
Be preferably, the cooperation place in described multidiameter shaft and described first hole is welded with weld part.
After employing technique scheme, the latch arm of the utility model latch assembly is provided with first hole identical with multidiameter shaft diameter, before welding latch arm and bolt axle, multidiameter shaft coordinates with the first hole thus keeps latch arm and bolt axle to arrange in 90 ° between the two, then uses welding machine to burn-on in the first hole and multidiameter shaft cooperation circular contour place weld part.The structure of latch assembly is simple, convenient and practical, has good market application foreground.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the topology view of the utility model latch assembly latch arm;
Fig. 2 is the topology view of the utility model latch assembly bolt axle;
Fig. 3 is the topology view of the utility model latch assembly;
Fig. 4 is the side view of the utility model latch assembly.
Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 1 to 4, latch assembly is coordinated by latch arm 1 and bolt axle 2 and forms, and latch arm 1 comprises main body 11, arrange the diameter that the diameter in the first hole 111 on the main body 11 and the second hole 111, hole 112, first is greater than the second hole 112.Bolt axle 2 comprises axis body 21, is arranged on the multidiameter shaft 22 of axis body 21 1 end, is arranged on the tapered portion 23 of axis body 21 the other end, and the diameter of multidiameter shaft 22 is less than the diameter of axis body 21.The diameter in the first hole 111 is identical with the diameter of multidiameter shaft 22.
When assembling latch assembly, first make the multidiameter shaft 22 of bolt axle 2 coordinate with the first hole 111 of latch arm 1, latch arm 1 is vertical between the two with bolt axle 2 and keep 90 °.Then to be burn-on in the cooperation place in multidiameter shaft 22 and the first hole 111 weld part 3 by welding machine, weld part 3 is distributed in the circumference profile of multidiameter shaft 22.Because the diameter in the first hole 111 is identical with the diameter of multidiameter shaft 22, thus before welding, multidiameter shaft 22 coordinates with the first hole 111 and maintains between multidiameter shaft 22 with latch arm 1 and coordinates in 90 °.
The latch arm 1 of the utility model latch assembly is provided with first hole 111 identical with multidiameter shaft 22 diameter, before welding latch arm 1 and bolt axle 2, multidiameter shaft 22 coordinates with the first hole 111 thus keeps latch arm 1 and bolt axle 2 to arrange in 90 ° between the two, and then use welding machine coordinates circular contour place to burn-on weld part 33 in the first hole 111 and multidiameter shaft 22.The structure of latch assembly is simple, convenient and practical, has good market application foreground.
Last it is noted that above embodiment only illustrates the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
