Abstract
The utility model relates to a fixing device for an air chamber. The fixing device comprises an air chamber body and a connecting piece, wherein an air cavity is formed in the air chamber body; the air chamber body is fixed on the connecting piece through a screw; the top of the screw is arranged in the air chamber body; a convex part is arranged in the position, where the screw is located, of the air chamber body; and the convex part arranged in a groove of the connecting piece and used for improving the connection strength between the air chamber body and the connecting piece. In a usage process of the fixing device for the air chamber, gas in the air cavity of the air chamber body cannot affect the screw connected between the air chamber body and the connecting piece; and at the same time, the convex part is arranged on the air chamber body, so that the connection strength between the air chamber body and the connecting piece is improved, and the situations of loose connection between the air chamber body and the connecting piece and air chamber leakage are effectively avoided.
Description
Technical field
The utility model relates to a kind of fixing device of air chamber.
Background technique
Prior art is fixedly connected with by screw 4 as between air chamber body 1 as described in accompanying drawing 1 and link 2, but the top of screw 4 is arranged in the air cavity 3 of air chamber body 1, this makes air chamber, and in air chamber body 1, the gas in air cavity 3 can be to the screw 4 outside active forces of generation in the inner in the process of using, reduce the fastening effect of screw 4, thereby make air chamber body 1 become flexible with the appearance that is connected between link 2; Gas in air cavity 3 can be run out of from the joint between air chamber body 1 and link 2 and screw 4 simultaneously, has caused the gas leakage of air chamber.
The model utility content
The utility model purpose is the fixing device that a kind of air chamber is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of fixing device of air chamber, comprise air chamber body and link, and be provided with air cavity in described air chamber body; Described air chamber body is fixed by screws on link; The top of described screw is arranged in the air chamber body; The position at described air chamber body screw place within it is provided with protuberance, and described protuberance is arranged in the groove of link, to improve the join strength between air chamber body and link with it.
Preferably, fix by two screws between described air chamber body and link.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The fixing device of air chamber described in the utility model, because the screw that is used for connection air chamber body and link does not extend in the air cavity of air chamber body, make air chamber in the process of using, gas in its air chamber body in air cavity can not exert an influence to the screw that is connected between air chamber body and link, be provided with protuberance on the air chamber body simultaneously, improved the join strength between air chamber body and link, effectively avoided being connected situation loosening and air chamber gas leakage between air chamber body and link.
Description of drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the schematic diagram of the fixing device of the described air chamber of prior art;
Accompanying drawing 2 is the schematic diagram of the fixing device of air chamber described in the utility model;
Wherein: 1, air chamber body; 2, link; 3, air cavity; 4, screw; 5, protuberance; 6, groove.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 2 is the fixing device of a kind of air chamber described in the utility model, comprises air chamber body 1 and link 2, is provided with air cavity 3 in described air chamber body 1; Described air chamber body 1 is fixed on link 2 by screw 4; The top of described screw 4 is arranged in air chamber body 1; The position at described air chamber body 1 screw 4 places within it is provided with protuberance 5, and in described protruding 5 grooves 6 that are arranged on link 2, to improve the join strength between air chamber body 1 and link 2 with it.
Fixing by two screws 4 between wherein said air chamber body 1 and link 2.
The fixing device of air chamber described in the utility model is in the process of using, gas in its air chamber body 1 in air cavity 3 can not exert an influence to the screw 4 that is connected between air chamber body 1 and link 2, be provided with protuberance 5 on air chamber body 1 simultaneously, improved the join strength between air chamber body 1 and link 2, effectively avoided being connected situation loosening and air chamber gas leakage between air chamber body 1 and link 2.
Be only below concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
