Wherein, 11- housing unit, 111- threaded hole, 112- annular groove, 113- counterbore section, 114- annular brace platform, 12- Screw, 121- load segment, 122- nut, 13- sealing ring.

Specific embodiment

The core of the utility model is to provide a kind of housing assembly, the sealing structure effect at the screw hole of the housing assembly Preferably, the overall sealing performance and its water proof and dust proof ability of actuator housing can be significantly improved；Meanwhile it providing in a kind of application State the driver of housing assembly.

In order to make those skilled in the art better understand the scheme of the utility model, with reference to the accompanying drawing and specific implementation The utility model is described in further detail for mode.

Fig. 1 and Fig. 2 are please referred to, Fig. 1 is the structure of housing assembly provided by a kind of specific embodiment of the utility model Cross-sectional view；Fig. 2 is the partial structure sectional view of part A in Fig. 1.

In a specific embodiment, housing assembly provided by the utility model, including housing unit 11, housing unit 11 It is upper that there is threaded hole 111, screw 12 is removably provided in threaded hole 111, screw 12 includes being plugged in threaded hole 111 Load segment 121 and nut 122 positioned at 121 outer end of load segment, outer wall and screw thread of the thread segment close to one end of nut 122 It is provided with sealing ring 13 with fitting closely between the inner wall in hole 111.

It assembles in use process, is sealed by the way that sealing ring 13 is reliable to implementation at the cooperation between screw 12 and threaded hole 111, To effectively avoid because at threaded hole 111 and 12 cooperation of screw sealing effect it is poor caused by actuator device overall tightness Can be bad, to guarantee the integral waterproofing dirt exclusion capabilities of the housing assembly, with guarantee driver overall operation stability and Functional reliability.

It should be noted that close respectively between the inner wall of the outer wall and threaded hole 111 of above-mentioned sealing ring 13 and thread segment paste Properly match, enables screw 12 and 111 coordinated of threaded hole to implement radial compaction limit to sealing ring 13, to have Effect guarantees the gluing, sealing effect between the assembly intensity and its adapter related to screw 12 and threaded hole 111 etc. of sealing ring 13.

Further, there is annular groove 112, sealing ring 13 is in annular groove 112 on the inner wall of threaded hole 111.It should Annular groove 112 can effectively ensure that the assembly intensity and its assembly reliability of sealing ring 13, and avoid 13 main structure of sealing ring Interference or other adverse effects are generated to the assembling structure between screw 12 and threaded hole 111, thus in the phase for guaranteeing sealing ring 13 While closing sealing effect, the assembly reliability between screw 12 and threaded hole 111 is effectively ensured.

Specifically, there is the counterbore section 113 being adapted to nut 122, annular groove 112 is located at heavy at the aperture of threaded hole 111 The inner end of hole section 113, and formed between in the inner wall outer of annular groove 112 and the inner wall of counterbore section 113 and to be abutted with nut 122 Annular brace platform 114.After the assembly is completed, which can provide enough structure branch for 122 inner face of nut Support guarantees the opposite rigging position between screw 12 and threaded hole 111, with screwless 12 is excessively assembled and to phases such as sealing rings 13 It closes matching piece and generates excessive compression or other structures interference phenomenon；Meanwhile counterbore section 113 can be implemented centainly to tie to nut 122 Structure protection, avoids nut 122 from being directly exposed to outside housing unit 11, so that nut 122 and the whole of screw 12 be made to use Service life is correspondinglyd increase.

More specifically, the axis phase of annular brace platform 114 and plane and threaded hole 111 where the contact surface of nut 122 Vertically.This kind planar structure vertical with 111 axis of threaded hole can effectively improve between annular brace platform 114 and nut 122 Contact area optimizes the stress distribution between the two at contact surface, guarantees that the assembly between screw 12 and 111 dependency structure of threaded hole is strong Degree and structural reliability.

On the other hand, screw 12 is full tooth screw 12 or half tooth screw 12.In practical application, no matter screw 12 uses full tooth Or half any structure in tooth, should ensure that screw 12 can with sealing ring 13 reliably fitting be adapted to, to guarantee sealing ring 13 To the sealing effect of fit structure between screw 12 and threaded hole 111.

In addition, sealing ring 13 is rubber seal 13 or plastic cement sealing ring 13.Certainly, it is contemplated that the use in practical application Cost and work condition environment, staff are also conceivable to realize using the sealing ring 13 of other materials to screw 12 and threaded hole Sealing structure at 111 cooperations, in principle, as long as the actual use that can satisfy the housing assembly needs.

In a specific embodiment, driver provided by the utility model, including housing assembly and be located at the shell Body inside body assembly, the housing assembly are such as housing assembly as described in the examples above.The sealing structure of the driver Property is preferable, and water proof and dust proof ability is stronger.

In summary, the housing assembly provided in the utility model assembles in use process, by sealing ring to screw Implement reliable sealing at cooperation between threaded hole, to effectively avoid due to threaded hole and sealing effect at screw fit are poor Caused actuator device overall sealing performance is bad, to guarantee the integral waterproofing dirt exclusion capabilities of the housing assembly, to protect Demonstrate,prove the overall operation stability and functional reliability of driver.

In addition, the driver provided by the utility model using above-mentioned housing assembly, sealing structure is preferable, waterproof Dirt exclusion capabilities are stronger.

It has been carried out in detail to housing assembly provided by the utility model and using the driver of the housing assembly above It introduces.Specific case used herein is expounded the principles of the present invention and embodiment, above embodiments Illustrate the method and its core concept for being merely used to help understand the utility model.It should be pointed out that for the general of the art For logical technical staff, without departing from the principle of this utility model, several improvement can also be carried out to the utility model And modification, modifications and modifications also fall within the protection scope of the claims of the utility model.
