Abstract
The utility model relates to a spinning air cap for tyres of vehicles such as bicycles, electric bicycles of toys for children and the like. The spinning air cap comprises an inner cover made of engineering plastic materials and an outer cover sleeved on the outer wall of the inner cover, wherein the inner hole of the inner cover is connected with a valve cock through screw threads, the outer wall of the inner cover is evenly distributed with a plurality of straight line shaped longitudinal keys along the circumference, and meanwhile, the root of the inner wall of the outer cover is evenly distributed with key grooves which correspond to the keys along the circumference, and the key grooves comprise a circular arc segment with circular arc strike and a straight line segment with straight line strike in the longitudinal direction, wherein the circular arc segment is closed to the bottom of the inner cover, and the straight line segment is closed to the bottom of the outer cover. The spinning air cap not only can be conveniently connected on the valve cock, but also can be prevented from taking down by children easily, and the security is excellent.
Description
Technical field
The utility model relates to a kind of spinning type gas cap that is used for vehicle tires such as bicycle, toy for children Electrical Bicycle.
Background technology
On the tire valve of vehicles such as various bicycles, toy for children Electrical Bicycle, be stamped the tire gas cap usually, be connected by screw thread fit between common gas cap and the tire tube valve of tire.On some vehicles that use for children, children are easy to from tire tube valve gas cap be screwed off, and the less gas cap of volume is swallowed by children easily and caused danger.
Summary of the invention
Technical problem to be solved in the utility model is that providing a kind of can be connected on the tire tube valve easily, can prevent the spinning type gas cap that children take off easily again.
The utility model spinning type gas cap is made up of the inner cap of engineering plastic materials and the enclosing cover that is enclosed within on the interior cover outer wall, the endoporus of inner cap and tire tube valve are by being threaded, the outer wall upper edge circumference of inner cap is evenly distributed with many rectilinear keys longitudinally, and the root at the enclosing cover inwall is evenly distributed with and the corresponding keyway of key along circumference simultaneously; Described keyway is made up of the arc section of one section circular arc trend and the linear portion of one section straight line trend in the vertical, and arc section is near the bottom of inner cap and the bottom of the close enclosing cover of linear portion.
Near the opening of described enclosing cover inwall is provided with restriction protrusion, and interior cover outer wall is provided with pawl simultaneously; One side of the close inner cap bottom of described pawl is a guiding surface.When enclosing cover cover inward upper cover, utilize the directional tagging of guiding surface and the elastic deformation of material that pawl is entered in the enclosing cover by the restriction protrusion that covers outward, and after pawl is by restriction protrusion, can stop restriction protrusion, prevent that enclosing cover from deviating from.
Utilize rectilinear key to match between inner cap of the present utility model and the enclosing cover with the keyway of circular arc and straight line combined shaped, when enclosing cover is subjected to longitudinal pressure can with inner cap interlock and drive inner cap rotation mutually, inner cap can be spun with tire tube valve to be cooperated, and when outside cover when not having longitudinal pressure, the arc section of keyway can utilize the key that covers in the elasticity general of material to release keyway, make the rotation of enclosing cover can't drive inner cap, thereby prevented that children from taking off whole valve cap easily, improved safety in utilization.
Description of drawings
Fig. 1 is the installing condition structural representation of the utility model embodiment;
Fig. 2 is the perspective view of inner cap of the present utility model.
The specific embodiment
As shown in the figure, this spinning type gas cap is made up of the inner cap 1 of engineering plastic materials and the enclosing cover 2 that is enclosed within on the interior cover outer wall, and inner cap is connected with tire tube valve 3 by the negative thread on its endoporus, realizes the sealing to tire tube valve.The outer wall upper edge circumference of inner cap 1 is evenly distributed with many rectilinear keys longitudinally 11, and the root of enclosing cover 2 inwalls is evenly distributed with and the corresponding keyway 21 of key along circumference; Keyway 21 is made up of the arc section 211 of one section circular arc trend and the linear portion 212 of one section straight line trend in the vertical, and arc section is near the bottom of inner cap 1, and linear portion is near outer 2 bottom.When needs with inner cap 1 when tire tube valve 3 screws off, as long as impose longitudinal pressure to enclosing cover 2, the key 11 that covers in making is clamp-oned keyway 21, and enter linear portion 212 by arc section 211, make the key interlock mutually on keyway and the inner cap 1 on the enclosing cover 2, at this moment rotary outer cover just can drive inner cap and rotates simultaneously, and inner cap is screwed off; And when not having longitudinal pressure on the enclosing cover 2, the arc section 211 of keyway 21 can utilize the elasticity of material that the key on the inner cap 1 11 is released keyway 21, even at this moment rotary outer cover 2 also can't drive inner cap 1 rotation, thereby has prevented that children from taking off whole valve cap easily, improved safety in utilization.
In order to make enclosing cover 2 difficult drop-offs that are enclosed within on the inner cap 1, near the inwall the opening of enclosing cover 2 is provided with restriction protrusion 22, and inner cap 1 outer wall is provided with pawl 12 simultaneously; One side of the close inner cap bottom of pawl 12 is a guiding surface 121.When enclosing cover 2 cover inward upper covers 1, utilize the directional tagging of guiding surface and the elastic deformation of material that pawl 12 is entered in the enclosing cover by the restriction protrusion 22 that covers outward, and after pawl is by restriction protrusion, can stop restriction protrusion, prevent that enclosing cover from deviating from.
