Abstract
The utility model discloses a dust cap. The dust cap comprises a dust cap body (1) and is characterized by further comprising a fixing portion (2), and the dust cap body (1) is connected with the fixing portion (2) through a flexible connection rod (3). The dust cap can not fall easily in the use process, and is simple and compact in structure, convenient to assemble and suitable for being used in narrow and small space.
Description
Technical field
The utility model relates to a kind of dust cap, is specifically related to a kind of use on machine, particularly uses the dust cap of Drop-proof on automobile oil-way pipe.
Background technique
The dust cap of existing routine is round structure, and it can realize dust reduction capability, but conventional dust cap comes off after easily being shaken.Automobile inevitably can produce vibrations in use, after dust cap is shaken, easily comes off, thereby make dust enter oil circuit parts, causes fault.Nowadays the structure between auto parts and components is more and more compacter, and the relative movement between component is more and more complicated, the space between automobile component is more and more less simultaneously, is not easy to find the dust cap having come off in narrow space; And the dust cap having come off is easily stuck between parts, thereby cause mechanical failure.Moreover between parts, small space requires the Drop-proof design of dust cap to want compact and simple, is convenient to assemble at narrow space.
Model utility content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, provides a kind of and is not easy to take off, simple compact dust cap.
The utility model solves the problems of the technologies described above adopted technological scheme, and dust cap comprises dust cap body, also comprises fixing part, and dust cap body is connected by flexible jointing-rod with fixing part.
The beneficial effects of the utility model are difficult drop-offs in use, and are simple and compact for structurely convenient to assembling, are highly suitable in small space and use.Fixing part is fixed on oil-way pipe track bolt, prevents that dust cap from splitting away off in use; When maintenance or assembling, dust cap body need to be taken from parts, but fixing part is fixed on oil-way pipe track bolt, dust cap can not come off yet.
Preferred technological scheme, fixing part is ring body, inner wall of ring body is provided with ratchet.On fixing part inwall, have ratchet, even the bolt in dustproof portion is unclamped at assembling automobile, ratchet has anti-drop function, and dust cap can not fall down.
Preferred technological scheme, evenly arranges two or more ratchets on the inner wall of ring body of fixing part.Gu top evenly arranges a plurality of ratchets, there is better Drop-proof effect.
Preferred technological scheme, dust cap body is the cylindrical shell of end opening one end sealing.The shape of dust cap body designs as required, and the cylindrical shell of end opening one end sealing can cover on and need on dustproof parts.
Preferred technological scheme, dust cap body cylinder inboard wall is provided with ratchet.Ratchet plays and prevents the effect of coming off of dust cap body, while avoiding dust cap body to use, comes off.
Preferred technological scheme, evenly arranges two or more ratchets on the cylinder inboard wall of dust cap body.A plurality of ratchets are set, make the Drop-proof better effects if of dust cap body.
Preferred technological scheme, offers groove on flexible jointing-rod.Groove flexibly connects for absorbing the deformation that rod bending produces, and makes flexible jointing-rod have better bending effect, expands the selection range of flexible jointing-rod.
Accompanying drawing explanation
Fig. 1 is embodiment's plan view;
Fig. 2 is embodiment's plan view;
Fig. 3 is embodiment's worm's eye view.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 are embodiment's accompanying drawings of the whole optimal technical scheme of the utility model.
Dust cap comprises dust cap body 1, also comprises fixing part 2, and dust cap body 1 is connected by flexible jointing-rod 3 with fixing part 2.The structure of fixing part 2 has multiple, has worm structure, bayonet arrangement, keyway arrangements, rivet arrangement, pin connection etc., and fixing part 2 optimal technical scheme are selected ring body structurc.
The structure of dust cap body 1 also has multiple, as very soft membranaceous cap body, and hollow cylinder etc., the present embodiment accompanying drawing is depicted as the tube structure of optimal technical scheme.
In optimal technical scheme embodiment, on fixing part 2 inner wall of ring bodies, be provided with ratchet 21, be provided with ratchet 11 on the cylinder inboard wall of dust cap body 1, ratchet plays Drop-proof effect, two or more ratchet is evenly set, makes the Drop-proof better effects if of dust cap body 1, fixing part 2.
Flexible jointing-rod 3 connects dust cap body 1 and fixing part 2, the length of flexible jointing-rod 3 and selection are determined according to actual needs, flexible jointing-rod 3 can be flexibly connected or be fixedly connected with dust cap body 1, fixing part 2, also can be cast as integrative-structure with dust cap body 1 and fixing part 2.Any material of material all can produce deformation when bending, and flexible jointing-rod 3 is no exception, arrange groove 31 can be accommodating the volume that produces of flexible jointing-rod material deformation, make the resistance to bending of flexible jointing-rod 3 better.
Compared with prior art, dust cap of the present utility model, except dustproof effect, can be not easy to come off in use, and simply compact.
