Description

45-degree parting O-shaped sealing ring

Technical Field

The utility model relates to a sealing washer technical field especially relates to a 45 somatotype O type sealing washer.

Background

The O-ring is a rubber ring with a circular cross section, so the O-ring is called as an O-ring because the cross section is O-shaped, and is the most widely used one in hydraulic and pneumatic transmission systems, and the O-ring is widely applied to various mechanical equipment to realize sealing of the mechanical equipment. Specific sealing washer can be installed on shaft hole complex part usually to prevent that liquid such as lubricating oil in the mechanical equipment from coming out along axle type part seepage, and then realize mechanical equipment's sealed, when the impaired needs of sealing washer are changed, at first extract axle type part from cooperation hole department, later need with the hand or clamp hard with the sealing washer from getting off from axle type part, the change process is hard to waste time.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a 45-degree parting O-shaped sealing ring.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a45-degree parting O-shaped sealing ring comprises a sealing body, wherein a groove is formed in the upper end of the middle of the left side of the sealing body, the upper end of the right side of the sealing body is fixedly connected to one end of a connecting block, the other end of the connecting block is fixedly connected with a trapezoidal lug, the connecting block is clamped with the trapezoidal lug, an inner ring is arranged in the middle of the outer side of the sealing body, and empty grooves are formed in the middle of the inner side of the sealing body at equal intervals;

through above-mentioned technical scheme, be convenient for change, conveniently take up.

Furthermore, the sealing body is an elastic rubber body;

through above-mentioned technical scheme, long service life, elasticity is good, the resistance to compression.

Further, the angle between the outer side sections of the sealing body is 45 degrees;

by the technical scheme, the reciprocating motion is performed

The rotary motion can play a better sealing role, the structure is simple, the elasticity is good, and the service life is prolonged.

Furthermore, the trapezoidal bump is trapezoidal, and the cross section of the front end is smaller than that of the rear end;

through above-mentioned technical scheme, both can block its inside at the recess firmly, be difficult to loosen.

The utility model discloses following beneficial effect has:

the utility model discloses in, because sealing body can be under the exogenic action free deformation and for the open-loop type design, therefore, open sealing body's both ends and can directly overlap on axle type part with it, in addition, because recess and trapezoidal lug can fixed connection, sealing body cover so far after on axle type part, long-time back of using, sealing body can be impaired, after sealing body is impaired, when needing to dismantle impaired sealing body from axle type part, at this moment, so dismantle on recess and the trapezoidal lug, because trapezoidal lug is the rubber material, and rear end and recess oblique angle, conveniently take out, later just can dismantle this sealing washer from axle type part.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides an embodiment: the utility model provides a 45 somatotype O type sealing washer, including sealing body 1, sealing body 1's left side middle part upper end is provided with recess 4, sealing body 1's right side upper end fixed connection is in the one end of connecting block 6, the trapezoidal lug of other end fixed connection of connecting block 6 5, connecting block 6 and the 5 blocks of trapezoidal lug, sealing body 1's outside middle part is provided with inner circle 2, sealing body 1's inboard middle part equidistance is provided with dead slot 3, sealing body 1 internal surface is glossy arc, it is more troublesome to hold between the fingers, through dead slot 3's inside groove, when needs are changed, 3 alright in order to relax of two adjacent dead slots of clamp-up with the clip.

The sealing body 1 is an elastic rubber body, and has the advantages of long service life, good elasticity and compression resistance.

The angle between the outer cross-sections of the sealing body 1 is 45 DEG, reciprocating and

Trapezoidal lug 5's shape is trapezoidal, and the front end cross section is less than the rear end cross section, and trapezoidal lug 5 front end cross section is less, enters into the inside of recess 4 very easily, because the inside front end of recess 4 accords with trapezoidal lug 5 appearance, enters into the inside of recess 4 when trapezoidal lug 5 rear end, and trapezoidal lug 5's rear end cross section is greater than recess 4 front end area, both can block its inside at recess 4 firmly, is difficult to loosen.

The working principle is as follows: because the sealing body 1 can freely deform under the action of external force and is designed in an open-loop mode, the sealing body 1 can be directly sleeved on the shaft parts by opening two ends of the sealing body 1. In addition, because recess 4 and trapezoidal lug 5 can fixed connection, sealing body 1 cover so far after on axle type part, long-time back of using, sealing body 1 may be impaired, when sealing body 1 impaired back, when needing to dismantle impaired sealing body 1 from axle type part, at this moment, can dismantle recess 4 and trapezoidal lug 5 at first, because trapezoidal lug 5 is the rubber material, and rear end and recess 4 oblique angle, conveniently take out, later just can dismantle this sealing washer from axle type part.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
