Abstract

The utility model discloses a flexible cover of connecting rod, including tip portion seal port, middle part radiation fins and big tip seal port, a plurality of strengthening rib is located evenly to be equipped with by the neck outer wall is connected at tip portion seal port and middle part radiation fins, and evenly the interval is equipped with the sealing rib of tip portion on the inner wall of tip portion seal port. The utility model discloses set up the sealing rib of tip portion on tip portion seal port, can not only prevent that tip portion seal port is sunken to get into flexible cover, can also improve the sealed effect of tip portion seal port, establish big tip sealing rib on the inner wall of big tip seal port, improving the sealing up of flexible cover, prevent dust, muddy water preventing's effect, be equipped with the mould and add the muscle on the outer wall of big tip seal port, can guarantee big tip sealing rib's manufacturing and shaping to strengthen the intensity of big tip seal port.

Description

A kind of connecting rod telescopic
Technical field
The utility model belongs to manufactruing equipment of automobile technical field, relates to a kind of rubber seal, is specifically related to a kind of connecting rod telescopic.
Background technology
Telescopic for dust seal, prevents that foreign matter (dust, muddy water etc.) is attached to connecting rod in the power unit of motor vehicle. The thin-walled tubular that telescopic is formed by rubber elastomer, synthetic resin etc., has bellows portion.
The telescopic of prior art, small end seal and large end part seal mouth are all straight designs. Small end seal, due to insufficient strength, can cave in and enter bellows portion; In addition, the sealing effectiveness of small end seal and large end part seal mouth has much room for improvement.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of connecting rod telescopic.
The technical solution adopted in the utility model is:
A kind of connecting rod telescopic, comprise small end seal, middle part radiation fins and large end part seal mouth, the neck outer wall place being connected with middle part radiation fins at small end seal is evenly provided with several reinforcements, is evenly interval with small end sealed muscle on the inwall of small end seal.
Further, on the inwall of described large end part seal mouth, be evenly interval with large end part seal muscle.
Further, small end sealed muscle cross section is the circular arc of radius 0.6mm, the high 0.3mm of circular arc; Large end part seal muscle cross section is the circular arc of radius 1mm, the high 0.3mm of circular arc.
Further, small end is spaced apart the cross-sectional width of small end sealed muscle; Large end part interval is the cross-sectional width of large end part seal muscle.
Further, the outer wall of described large end part seal mouth is provided with mould reinforcement.
The utility model beneficial effect is obvious: (1) arranges small end sealed muscle on small end seal, can not only prevent that small end seal depression from entering telescopic, can also improve the sealing effectiveness of small end seal; (2) on the inwall of large end part seal mouth, establish large end part seal muscle, can improve the sealing of telescopic, the effect of dustproof, anti-muddy water; (3) on the outer wall of large end part seal mouth, be provided with mould reinforcement, can ensure manufacture and the moulding of large end part seal muscle, and strengthen the intensity of large end part seal mouth.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of small end sealed muscle.
Fig. 3 is the partial enlarged drawing of large end part seal muscle.
Reference numeral: small end seal 1, reinforcement 2, middle part radiation fins 3, large end part seal mouth 4, mould reinforcement 5, large end part seal muscle 6, small end sealed muscle 7.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further, but scope of the present utility model is not limited to following embodiment.
As shown in the figure, a kind of connecting rod telescopic, comprises small end seal 1, middle part radiation fins 3 and large end part seal mouth 4, and the outer wall of large end part seal mouth 4 is provided with mould reinforcement 5.
The neck outer wall place being connected with middle part radiation fins 3 at small end seal 1 is evenly provided with several reinforcements 2, is evenly interval with small end sealed muscle 7 on the inwall of small end seal 1; On the inwall of large end part seal mouth 4, be evenly interval with large end part seal muscle 6.
Small end sealed muscle 7 cross sections are the circular arc of radius 0.6mm, the high 0.3mm of circular arc; Large end part seal muscle 6 cross sections are the circular arc of radius 1mm, the high 0.3mm of circular arc.
Small end is spaced apart the cross-sectional width of small end sealed muscle 7; Large end part interval is the cross-sectional width of large end part seal muscle 6.
