The utility model discloses simple structure, low cost.
Description
[technical field]
The utility model relates to a kind of rotary buffer, specifically relates to a kind ofly to be used on water closet cover-plate and to extend a kind of rotary buffer of its fall time.
[background technology]
Seat lavatory is the staple in people's daily life, and on the cover plate in seat lavatory, the general bearing pin that adopts is connected directly between in toilet seat, or adopts spring buffer structure.With pin shaft structure, larger strike sound can be sent when putting down cover plate, and adopt spring buffer structure, easy rust corrosion and damaging.
Also the buffer structure using damping oil and carrying out to cushion is had in the market, cover plate well cushioned when can be made to put down, nor there will be the situation of corrosion, but this buffer structure requires very high to assembly precision, must ensure that damping oil is not revealed, therefore also just cause buffer structure complicated, the defect that cost is high.
Therefore, the utility model produces based on above deficiency just.
[utility model content]
The utility model object overcomes the deficiencies in the prior art, provides a kind of structure simple, rotary buffer with low cost.
The utility model is achieved through the following technical solutions:
A kind of rotary buffer, comprise stack shell 1 and concentric setting and the axle core 2 that can rotate to it, it is characterized in that: described stack shell 1 cross section of inboard wall ovalize, described axle core 2 is arranged with the elastic rubber sleeve 3 that can coordinate with stack shell 1 inwall, the external wall cross-section ovalize of described elastic rubber sleeve 3.
Rotary buffer as above, is characterized in that: described axle core 2 is provided with many convex tendons 4 be embedded in elastic rubber sleeve 3.
Rotary buffer as above, is characterized in that: described stack shell 1 inwall is provided with positioning convex 5, and described elastic rubber sleeve 3 is provided with the detent 6 matched with positioning convex 5.
Rotary buffer as above, is characterized in that: the cross section of described convex tendon 4 is for semicircle.
Rotary buffer as above, is characterized in that: described elastic rubber sleeve 3 is TPE rubber and plastic glue.
Compared with prior art, the utility model has the following advantages:
1, stack shell cross section of inboard wall ovalize of the present utility model, the external wall cross-section ovalize of elastic rubber sleeve sheathed on axle core, when the cover plate in seat lavatory puts down, flexible elastic rubber sleeve rotates in the oval endoporus of stack shell, therefore, along with the rotation of axle core, to interference fit be there is in elastic rubber sleeve and stack shell inwall, the angle of rotating is larger, the magnitude of interference of interference fit is also larger, thus the falling speed of the cover plate that slows down, well cushioned, and, elastic rubber sleeve is set on axle core, and coordinate with stack shell, a whole set of structure is very simple, reduce the amount of parts of conventional buffer structure, reduce costs.
2, axle core of the present utility model is provided with many convex tendons be embedded in elastic rubber sleeve, and convex tendon makes elastic rubber sleeve be connected tightr with axle core, and the situation that there will not be axle core and elastic rubber sleeve to relatively rotate and skid ensure that the steady quality of buffer structure.
3, stack shell inwall of the present utility model is provided with positioning convex, elastic rubber sleeve is provided with the detent matched with positioning convex, positioning convex coordinates with detent, axle core can be made to rest on desired position, play spacing effect to the cover plate opened completely.
4, the utility model structure is simple, with low cost, easily manufactured, is applicable to promoting.

Fig. 2 is exploded view of the present utility model;
Fig. 3 is the profile of the utility model when water closet cover-plate is opened completely;
Fig. 4 is that the utility model starts profile when putting down at water closet cover-plate;

[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is further described:
A kind of rotary buffer, comprise stack shell 1 and concentric setting and the axle core 2 that can rotate to it, described stack shell 1 cross section of inboard wall ovalize, described axle core 2 is arranged with the elastic rubber sleeve 3 that can coordinate with stack shell 1 inwall, the external wall cross-section ovalize of described elastic rubber sleeve 3.When the cover plate 7 in seat lavatory puts down, flexible elastic rubber sleeve 3 rotates in the oval endoporus of stack shell 1, therefore, along with the rotation of axle core 2, will there is interference fit in elastic rubber sleeve 3 and stack shell 1 inwall, the angle of rotation is larger, the magnitude of interference of interference fit is also larger, thus the falling speed of the cover plate 7 that slows down, well cushioned, and, elastic rubber sleeve 3 is set on axle core 2, and coordinates with stack shell 1, and a whole set of structure is very simple, reduce the amount of parts of conventional buffer structure, reduce costs.
Described axle core 2 is provided with many convex tendons 4 be embedded in elastic rubber sleeve 3.Convex tendon 4 makes elastic rubber sleeve 3 be connected tightr with axle core 2, there will not be axle core 2 and elastic rubber sleeve 3 to relatively rotate and the situation of skidding, ensure that the steady quality of buffer structure.
Described stack shell 1 inwall is provided with positioning convex 5, and described elastic rubber sleeve 3 is provided with the detent 6 matched with positioning convex 5.Positioning convex 5 coordinates with detent 6, and axle core 2 can be made to rest on desired position, plays spacing effect to the cover plate 7 opened completely, make cover plate 7 can not continue arrive needed for open position time be no longer rotated further.
The cross section of described convex tendon 4 is semicircle.The cross section of convex tendon 4 also can be triangle, trapezoidal or other shapes.
Described elastic rubber sleeve 3 is TPE rubber and plastic glue.TPE rubber and plastic glue is a kind of high resiliency with rubber, high strength, high resilience, and having again can the material of feature of injection molding.Have environment-protecting asepsis safety, hardness range is wide, and have excellent coloring, soft-touch, weatherability, fatigue resistance, temperature tolerance and processing characteristics are superior, and cost is very cheap.
Utility model works principle:
As shown in Figure 3 and Figure 6, now cover plate 7 is erect and rests on the position of opening, and due to the existence of positioning convex 5 and detent 6, so cover plate 7 can not continue to rotate counterclockwise, ensure that the position location of cover plate 7.When needs put down cover plate 7, axle core 2 rotates clockwise (as shown in Figure 4,5), because the endoporus of the elastic rubber sleeve 3 on axle core 2 and stack shell 1 is concentration ellipse structure.When axle core 2 rotates, elastic rubber sleeve 3 will produce interference friction phenomenon with stack shell 1 inwall, makes axle core 2 form larger moment of torsion.Because being elastic rubber sleeve 3 outer wall and stack shell 1 inwall is concentration ellipse relation, axle core 2 rotational angle is larger, the magnitude of interference between elastic rubber sleeve 3 and stack shell 1 is also larger, so cover plate 7 just under come to more and more slower, thus reach buffering effect, there will not be very large strike note when cover plate 7 is fallen in toilet seat 8.And when cover plate 7 opened by needs, when axle core 2 is rotated counterclockwise, in the process that axle core 2 rotates, gap between elastic rubber sleeve 3 and stack shell 1 inwall also can be increasing, when detent 6 turns to positioning convex 5 position, axle core 2 can not continue to rotate counterclockwise, and now cover plate 7 is also just in required open position.
