Abstract
The utility model relates to a kind of screwed assembly of built-in spring, including knob assembly, spring and screw, internal screw thread is set, the spring is set in the internal screw thread of knob assembly, and the knob assembly is connected with screw thread inside the knob assembly.The utility model connection component built-in spring in knob assembly, then it is fastenedly connected by screw, it can effectively be connected between two plastic parts for having relative motion, prevent the screw thread as caused by relative motion from loosening failure and coupling mechanism force excessive the problem of leading to sliding teeth.
Description
Technical field
The utility model relates to plastic device attachment device fields, and in particular to a kind of threaded connection group of built-in spring
Part.
Background technique
Currently, well known plastic whorl connection, one is screw thread is molded in injection molding, such screw strength is relatively
Low, when coupling mechanism force is larger, screw thread is easy to sliding teeth；When another kind is injection molding while it being embedded in thread bush, although this mode can
To bear biggish coupling mechanism force, but do not have locking functions, in the case where screw and screw thread need the operating condition of relative motion, screw
It is easy to loosen, eventually leads to Joint failure.
Utility model content
The purpose of this utility model is to provide a kind of screwed assemblies of built-in spring, to solve in the prior art
Plastic whorl connection the problem of being easy to appear sliding teeth and Joint failure.
The utility model provides a kind of screwed assembly of built-in spring, including knob assembly, spring and screw, institute
It states and internal screw thread is set inside knob assembly, the spring is set in the internal screw thread of knob assembly, the knob assembly and screw
It is threadedly coupled.
It further, further include sliding block and handle.
Further, the sliding block and handle are arranged between knob assembly and screw, are fixed by screwing screw.
Further, the material of the knob assembly is plastics.
Beneficial effect using above-mentioned technical solutions of the utility model is:
The utility model connection component built-in spring in knob assembly, is then fastenedly connected by screw, can be two
Effectively connected between a plastic part for having relative motion, prevent the screw thread as caused by relative motion loosen failure and
Coupling mechanism force excessive the problem of leading to sliding teeth.
Detailed description of the invention
Fig. 1 is the utility model connecting component structure schematic diagram；
Fig. 2 is A-A sectional view in Fig. 1；
Fig. 3 is the utility model connection component use state decomposition diagram；
In attached drawing, parts list represented by the reference numerals are as follows:
1- knob assembly, 2- spring, 3- sliding block, 4- handle, 5- screw
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.
As shown in Figure 1-3, the utility model provides a kind of screwed assembly of built-in spring, including knob assembly 1,
Internal screw thread is arranged inside knob assembly 1 in spring 2 and screw 5, and spring 2 is set in the internal screw thread of knob assembly 1, knob assembly 1
It is threadedly coupled with screw 5.
Specifically, further including sliding block 3 and handle, sliding block 3 and handle are arranged between knob assembly 1 and screw 5, pass through rotation
It is fixed to twist screw 5.
1 material of knob assembly is plastics, in injection molding, has molded internal screw thread, or corresponding using threading apparatus tapping
Then screw thread is screwed into corresponding spring 2 in 1 internal screw thread of knob assembly with tool, built-in spring 2 and then with 5, screw
The locking of two parts, using the elastic force of spring 2, can significantly supplement screw thread in this way when carrying out the one of part of back rotation
Coupling mechanism force, make screw 5 be not easy to loosen.
To sum up, the utility model connection component built-in spring in knob assembly, is then fastenedly connected by screw, can be with
It is effectively connected between two plastic parts for having relative motion, prevents the screw thread as caused by relative motion from loosening mistake
Effect and coupling mechanism force excessive the problem of leading to sliding teeth.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
