Background technology
Nowadays wrist-watch is more and more welcomed by the people, though be have a meal, have a bath, work, travel, swimming etc., people can with wrist-watch.But conventional wristwatch on market is good not due to the sealing of bottom, thus can intakes, even enter dust, affect the precision of wrist-watch, performance and serviceable life.
Therefore need to improve bottom cover of watch, the sealing sealing of bottom cover of watch is increased, thus make the precision of wrist-watch and performance can not enter water because sealing is poor or dust affects.
Utility model content
The purpose of this utility model is that providing a kind of installs simple watchcase, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of bottom cover of watch of good airproof performance, comprise watchcase, bottom, bottom internal thread, draw-in groove, bottom external thread, bottom threaded top and rubber washer, described bottom is by bottom internal thread, draw-in groove and bottom external thread composition, described bottom adopts the method for inside and outside two screw thread, described bottom internal thread and bottom external thread by the process of tapping attack respectively bottom inner surface wall and bottom appearance wall on, described bottom threaded top is processed into semicircular arc by the craft method of polishing, described draw-in groove is arranged on the edge bottom bottom uniformly, described watchcase is by groove external thread, groove internal thread, form with groove, described rubber washer sticks in the top of groove by PVC seccotine, described groove external thread and groove internal thread are attacked on the appearance wall of groove and the inner surface wall of groove respectively by the process of tapping.
Preferably, the spacing between described groove external thread and groove internal thread will meet bottom external thread and bottom internal thread closely screws with it mutually.
Preferably, the degree of depth of described groove is identical with the height of bottom threaded top, and the top of described groove is semicircular arc, and 1/3rd of the arc radius of groove rubber washer thickness larger than the arc radius of bottom threaded top.
Preferably, described draw-in groove is four little shrinkage pools of circle, is uniformly distributed bottom bottom margin place.
Compared with prior art, the beneficial effects of the utility model are: this bottom cover of watch adopts the method for inside and outside two screw thread, the sealing of bottom cover of watch the is had raising of matter, fundamentally solve bottom cover of watch to intake or the problem of dust because sealing difference, the precision of wrist-watch and performance are effectively ensured, extends the serviceable life of wrist-watch.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only 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 the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-3, the utility model provides a kind of technical scheme: a kind of bottom cover of watch of good airproof performance, comprise watchcase 1, bottom 4, bottom internal thread 5, draw-in groove 6, bottom external thread 7, bottom threaded top 8 and rubber washer 9, bottom 4 is made up of bottom internal thread 5, draw-in groove 6 and bottom external thread 7, bottom 4 adopts the method for inside and outside two screw thread, and the method for inside and outside pair of screw thread effectively can ensure the sealing of bottom 4.Bottom internal thread 5 and bottom external thread 7 are attacked on the appearance wall of 4 of bottom 4 inner surface wall and bottom respectively by the process of tapping, screw simultaneously, bottom 4 is screwed tightr inside and outside bottom internal thread 5 and bottom external thread 7.Bottom threaded top 8 is processed into semicircular arc by the craft method of polishing, makes bottom threaded top 8 stressed more even, fits more airtight.Draw-in groove 6 is arranged on the edge bottom bottom 4 uniformly, when draw-in groove 6 is for installing or removing bottom 4, and the engaging of specific purpose tool and bottom 4.Watchcase 1 is made up of groove external thread 2, groove internal thread 3 and groove 10, and rubber washer 9 sticks in the top of groove 10 by PVC seccotine, makes rubber washer 9 remain on the top of groove 10 by the adhesion of seccotine.Groove external thread 2 and groove internal thread 3 are attacked on the appearance wall of groove 10 and the inner surface wall of groove 10 respectively by the process of tapping, and bottom external thread 7 and bottom internal thread 5 are screwed with it.The spacing of groove external thread 2 and groove internal thread 3 will make bottom external thread 7 and bottom internal thread 5 mutually closely screw with it, makes the better tightness of bottom cover of watch.The degree of depth of groove 10 is identical with the height of bottom threaded top 8, and bottom 4 threaded walls is screwed completely in groove 10.The top of groove 10 is semicircular arc, and the arc radius of groove 10 is than 1/3rd of the arc radius of bottom threaded top 8 large rubber washer 9 thickness, rubber washer 9 is flexible and durable, threaded walls can be made to enter in groove 10 completely by rotating bottom 4, and bottom threaded top 8 pushes up pressure rubber washer 9, makes to have flexible rubber washer 9 and is filled in groove 10 top and the remaining space of bottom threaded top 8.Draw-in groove 6 is four little shrinkage pools of circle, is uniformly distributed bottom 4 bottom margin place, and when making dismounting bottom 4, special tool prodigiosin evenly exerts a force, easy disassembly.
The key of bottom cover of watch sealing is the employing of the two screw thread of appearance wall in bottom 4; Bottom internal thread 5 in bottom 4 and bottom external thread 7 closely screw with groove internal thread 3 and groove external thread 2 respectively; And after threaded engagement, semicircular arc bottom top 8, closely to engage between rubber washer 9 and groove 10 top of semicircular arc.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
