Abstract
The utility model discloses a dead-corner-free sealing mechanism which comprises an upper sealing body (10) and a lower sealing body (12), wherein the upper sealing body (10) is provided with an upper sealing surface (14), the lower sealing body (12) is provided with a lower sealing surface (16), the upper sealing surface (14) and the lower sealing surface (16) are arranged oppositely, a sealing groove (18) is formed in the upper sealing surface (14), an elastic annular ring (20) is arranged in the sealing groove (18), and the sealing groove (18) is provided with two lateral walls (22). The dead-corner-free sealing mechanism is characterized in that height difference (24) exists between the two lateral walls (22). The dead-corner-free sealing mechanism is good in sealing performance, free of dead corner, and suitable for being used in an environment with high cleanness requirements.
Description
Technical field
The utility model relates to a kind of sealing mechanism, relates in particular to a kind of sealing configuration without dead angle.
Background technique
As everyone knows, conventionally can use various sealing mechanisms aborning, to prevent the leakage of liquid or gas medium, wherein O type rubber ring is more common a kind of Sealing, most widely used general in Qi hydropneumatic mechanism, there are the little mounting or dismounting of size convenient, static and dynamic sealing is the advantage such as available all, yet while being used in conjunction with, still there will be other problem, sealing mechanism as shown in Figure 1, comprise seal 1 and lower seal body 3, on upper seal 1 and lower seal body 3, there is respectively the upper sealing surface and the lower sealing surface that arrange in opposite directions, on upper sealing surface, offer seal groove, O type rubber ring 2 is arranged in seal groove, upper seal is oppressed O type rubber ring 2 in lower sealing surface, because O type rubber ring 2 is rubber material, therefore, after being squeezed, its part of stretching out seal groove can produce to both sides deformation, cannot tight closure thereby make between sealing surface and lower sealing surface, to such an extent as to generation gap, the existence in this gap easily becomes the residual dead angle of medium, easily cause bacteria breed, so above-mentioned sealing mechanism cannot be applicable to clean industry, cannot be applicable to the industry higher to health class requirement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of sealing better and does not have the sealing mechanism at dead angle.
For solving the problems of the technologies described above, the utility model provides a kind of sealing mechanism without dead angle, comprise seal and lower seal body, on described upper seal, have upper sealing surface, on described lower seal body, have lower sealing surface, described upper sealing surface and described lower sealing surface arrange in opposite directions, on described upper sealing surface, offer seal groove, in described seal groove, be provided with and have flexible ring-like circle, described seal groove has two sidewalls, between described two sidewalls, has height difference.
Described ring-like circle is O type rubber ring.
Described upper sealing surface and described lower sealing surface are sealing plane.
In two sidewalls of described seal groove, the sidewall at nearly described upper sealing surface edge is lower than another sidewall, and when the height difference between described two sidewalls can make described ring-like circle stressed, only the side compared with low sidewall to described seal groove produces deformation.
Compared with prior art, the beneficial effects of the utility model are:
Between two sidewalls due to seal groove in sealing mechanism of the present utility model, there is height difference, like this when the ring-like circle of compressing, it only can produce deformation to the side compared with low sidewall, go up so just complete closed, the close contact of energy of sealing surface and lower sealing surface, between can there is not any gap, thereby do not have dead angle, exist, to such an extent as to do not have bacteria breed, therefore the utility model sealing better and do not have dead angle, can be applicable in environment that cleaning has relatively high expectations preferably.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing sealing mechanism;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of upper seal in the utility model;
In figure: upper seal 10, lower seal body 12, upper sealing surface 14, lower sealing surface 16, seal groove 18, ring-like circle 20, sidewall 22, height difference 24.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail
Shown in Fig. 2 and Fig. 3, a kind of sealing mechanism without dead angle of the present utility model, include seal 10 and lower seal body 12, wherein go up and on seal 10, there is upper sealing surface 14, on lower seal body 12, there is lower sealing surface 16, preferably upper sealing surface 12 and lower sealing surface 14 are plane, and upper sealing surface 14 and lower sealing surface 16 arrange in opposite directions, wherein, on upper sealing surface 14, offer seal groove 18, in sealing groove 18, be provided with and there is flexible ring-like circle 20, preferably annular ring 20 is O type rubber ring, this O type rubber ring is arranged in seal groove 18, and the outside that part is stretched out seal groove 18, seal groove 18 has two sidewalls 22 that contact with 0 type rubber ring surface, focus on: between these two sidewalls 22, have height difference 24, be that a sidewall of seal groove 18 is higher than another sidewall, because antermarginal sidewall is lower than another sidewall, make like this both sides of seal groove 18 be step-like (referring to Fig. 3), this structural design makes that it only produces deformation to a side during 0 type rubber ring in compressing, to the lower side of sidewall or the lower side of step, produce deformation, simultaneously, height difference between two sidewalls 22 can be accommodated the deformation that O type rubber ring produces completely, going up like this sealing surface 14 and lower sealing surface 16 just can be completely closed, close contact, between can there is not any gap, thereby not having dead angle exists, to such an extent as to do not have bacteria breed.
The foregoing is only better embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned mode of execution; in every case the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or is changed, and all should include in the protection domain of recording in claims.
