Abstract
The utility model discloses a screw bolt anti-loosing cover used for assembling parts, which is mushroom-shaped in the whole, and comprises a top cap and a connecting sleeve extending from the top cap, wherein the inner hole of the connecting sleeve is bigger than a bolt head, and is sleeved on the bolt head, the outer circumference of the lower end of the connecting sleeve is provided with a circuit of protruding edges which are matched with grooves on the assembling position of the screw bolt. The screw bolt anti-loosing cover is covered on the assembled bolt head, coats the bolt head, hooks the grooves of connecting parts through the protruding edges, restrains rotating inverse withdrawal of the screw bolt caused by vibration, prevents the screw bolt releasing caused by vibration generated in the traveling process of vehicles, avoids the connected parts from loosening, which leads to functions of parts to become invalid, and can better improve service life of related parts.
Description
Technical field
The utility model relates to the mounting technology of bolt.
Background technique
Usually, at automobile external opening handle, in open handle, it is fixedly connected to need to use bolt to carry out in the installation of component such as inside door handle and instrument panel, its major defect is that along with the vibrations of vehicle traveling process, bolt gets loose easily, cause the component that connected also loosening, cause the component disabler.Simultaneously, this kind bolt usually is exposed to component outsides, mouldedly seems attractive in appearance.For this reason, people attempt adopting chek bolt, but chek bolt manufacturing user cost is higher relatively again.
The model utility content
The technical problems to be solved in the utility model provides and a kind ofly is connected firmly, the assembling of service-strong part is covered with screw retention.
For solving the problems of the technologies described above, the utility model is taked following technological scheme:
The assembling of a kind of part is with the screw retention lid, and its integral body is mushroom shaped, by headkerchief and under headkerchief extended connecting sleeve form; The endoporus of described connecting sleeve is enclosed within on the bolt head greater than bolt head; Have on the lower end excircle of described connecting sleeve one the circle convex edge, with the bolts assemblies position groove fit.
This screw retention cover the bolt head that assembles, envelope bolt head, and by the convex edge hook connect the groove of component, counter the moving back of rotation that the restriction bolt brings because of vibration, prevent the vibrations that produce in the vehicle traveling process and the bolt that causes gets loose, and avoid causing the component that connected also loosening and cause component disabler, the working life that can improve related components preferably.
Description of drawings
Fig. 1 is the schematic representation of this part assembling with the screw retention lid
Fig. 2 is the assembling schematic representation of this part assembling with the screw retention lid
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail;
Is mushroom shaped referring to Fig. 1, the assembling of this part with screw retention lid integral body, is made up of curved surface headkerchief 1 and connecting sleeve 2.This connecting sleeve 2 is the column type cover, and its lower end exterior periphery is provided with convex edge 3.Shown connecting sleeve is the cylinder jacket among Fig. 1, also can be the polygon prism jacket, and the shown triangle of convex edge 3 for tilting also can be other shape that matches with outside component.
Referring to Fig. 2, when using the screw retention lid, the component of being installed are fixed earlier with bolt 5, connecting sleeve 2 with screw retention lid buckles into bolt head again, by tightly blocking, the convex edge 2 of screw retention lid hook connect the groove 4 of component, prevent that locking lid from coming off, the also anti-power of moving back of bearing bolt rotation prevents from that bolt is counter to move back.
Claims (3)
1, a kind of part assembling is characterized in that with the screw retention lid its integral body is mushroom shaped, is made up of headkerchief (1) extended connecting sleeve (2) under headkerchief; The endoporus of described connecting sleeve (2) is enclosed within on the bolt head greater than bolt head; Have on the lower end excircle of described connecting sleeve (2) one the circle convex edge (3), with the bolts assemblies position groove (4) cooperate.
