Abstract
The utility model discloses a bolt for an automobile. The bolt comprises a bolt body (20), wherein the bolt body (20) comprises a bottom and an upright part located at the center of the bottom; an annular metal gasket (21) parallel with the bottom is arranged at the upright part near the position of the bottom; and the bolt for the automobile is characterized in that the metal gasket (21) is embedded with an annular rubber layer (22), the outer diameter of the rubber layer (22) is smaller than that of the metal gasket (21), and the inner diameter of the rubber layer (22) is in interference fit with the upright part. The bolt used for the automobile, disclosed by the utility model, can play the sealing function without adding an extra sealing gasket and cannot cause torque loss. In addition, as the rubber layer is embedded on the metal gasket, the rubber layer cannot drop off the bolt body.
Description
Technical field
The utility model relates to a kind of bolt, and more particularly, the utility model relates to a kind of automobile and uses bolt.
Background technique
Because it is automobile mainly is in outdoor application, therefore very high to the requirement of sealing.The parts of body exterior need on vehicle body, perforate could use bolt to install, and these mounting holes all need sealing.Fig. 1 is the sectional drawing of bolt of the prior art.Bolt comprises the metallic shim 11 of bolt body 10 and annular.The foam that on bolt body 10, relies on the sheathed rubber-like of being close to metallic shim 11 of frictional force plays the effect of sealing vehicle body mounting hole as sealing gasket 12.Fig. 2 is to use the working section figure of the bolt of Fig. 1.After using bolt to be fastened on parts 14 on the plates of automobile 13, sealing gasket 12 is compressed, and plays the effect of the mounting hole on the sealing panel beating 13.But since between metallic shim 11 and the panel beating 13 across compressed sealing gasket 12, what therefore form is a kind ofly to be flexible coupling.As time goes on, being flexible coupling to cause loss of machine of torque, does not reach fastening requirement, even causes parts 14 to get loose, and influence is normally used.In addition, because sealing gasket 12 is to rely on frictional force to be set on the bolt body 10, therefore in transportation and operating process, sealing gasket 12 comes off from bolt body 10 easily.
The model utility content
For solving above-mentioned prior art problems, the utility model provides a kind of new automobile to use bolt.
The automobile of the utility model has bolt body with bolt; Said bolt body comprises bottom and the vertical portion that is positioned at said bottom centre; Be provided with and said bottom parallel annular metallic shim near the position of said bottom in said vertical portion, it is characterized in that, on said metallic shim, inlay the rubber layer of annular; The outside dimension of said rubber layer is less than the outside dimension of said metallic shim, and the internal diameter of said rubber layer and said vertical portion are interference fit.
Preferably, on said metallic shim, inlay said rubber layer through an inserts injection moulding or a mode of moulding.
Preferably, the height of the longitudinal profile of said rubber layer reduces from the internal diameter to the external diameter gradually.
Distance between said bottom and the metallic shim adapts with the component thickness of using said bolt.
Because the radial dimension of the rubber layer of inlaying on the metallic shim is less than the radial dimension of metallic shim; Therefore rubber layer can play the effect of sealing under the situation that need not extra increase sealing gasket; Do not hinder the contact between metallic shim and the plates of automobile simultaneously, thereby can not cause loss of machine of torque.In addition, because rubber layer is mounted on the metallic shim, therefore can in transportation and operating process, not come off from bolt body.
Description of drawings
Fig. 1 is the sectional drawing of bolt of the prior art.
Fig. 2 is to use the working section figure of the bolt of Fig. 1.
Fig. 3 is the sectional drawing of the bolt of the utility model.
Fig. 4 is to use the working section figure of the bolt of Fig. 3.
Embodiment
Below, be described in detail with bolt in conjunction with the automobile of accompanying drawing the utility model.
Similar with Fig. 1, the automobile of the utility model shown in Figure 3 has bolt body 20 with bolt.Bolt body 20 comprises bottom and the vertical portion that is positioned at said bottom centre.In the position of said vertical portion, be provided with and said bottom parallel annular metallic shim 21 near said bottom.Distance between said bottom and the metallic shim 21 can be different and different according to the thickness of treating fixed component.Different with the sheathed sealing gasket of existing technology 12 is, on metallic shim 21 through the inserts injection moulding, drip mode such as mould and inlay the rubber layer 22 of annular.Importantly, the outside dimension of the rubber layer 22 of annular is less than the outside dimension of endless metal pad 21, and promptly the edge of metallic shim 21 is not covered by rubber layer 22; In addition, the internal diameter size of rubber layer 22 is slightly less than the internal diameter of endless metal pad 21, makes rubber layer 22 to form interference fit, enhanced leaktightness effect with said vertical portion.As shown in Figure 3 equally, the height of the longitudinal profile of said rubber layer reduces from the internal diameter to the external diameter gradually.
As shown in Figure 4; When the bolt that uses Fig. 3 is fixed to panel beating 23 with parts 24; The mounting hole on the panel beating 23 passes in the vertical portion of bolt body 20; The part of parts 24 is stuck between the bottom of metallic shim 21 and bolt body 20, and rubber layer 22 has played the effect of sealing between metallic shim 21 and panel beating 23, does not therefore need extra increase sealing gasket.After rubber layer 22 was compressed, the edge of metallic shim 21 can contact with panel beating 23, therefore can not produce the phenomenon that is flexible coupling, and had avoided loss of machine of torque.In addition, owing to rubber layer 22 is embedded on the metallic shim 21, so it can not come off from bolt body 20.
It should be noted that; The bolt of the utility model not only can be used for automobile; Under the prerequisite of the essence that does not break away from the utility model, it may occur to persons skilled in the art that this bolt is used for the field that other need use the bolton sealing and not allow to produce loss of machine of torque.Thereby, all should work as in the scope that belongs to the utility model with revising the various deformation that the foregoing description carries out.
Claims (4)
