Abstract

The utility model relates to an anti-loosening bolt which comprises a bolt base body (1) and is characterized in that meshing threads (2) are arranged on the end surface of the bolt head end of the base body, the end surface of the bolt head end of the base body is matched with a connected component, and the matched surfaces are in meshing friction. The anti-loosening bolt has the beneficial effects that the meshing threads are arranged on the end surface of the bolt head end of the base body, and the end surface of the bolt head end of the base body is matched with the connected component, so that the anti-loosening bolt cannot easily slip; even if the bolt slips, fastening force still exists, so that the bolt can be meshed at the next meshing part and continuously have anti-loosening effect.

Description

Chek bolt

Technical field

The utility model relates in the mechanical part, especially a kind of chek bolt.

Background technique

That bolt generally is used for is fastening, the location, in use can make bolt looseness or displacement because of reasons such as vibrations, and some locking (cunning) measure will be based upon on the fastened basis of bolt; Such as elastic washer, but in the application that prevents to be shifted, because bolt does not possess fastened condition; The measure of much locking (cunning) can't be used; Get hanger bolt such as the suspending type sliding door, its fastening force is exactly the weight of hanging door, and the measure of general locking (cunning) can't be used.

The model utility content

The purpose of the utility model is exactly not possess locking defective in order to overcome existing bolt, and a kind of chek bolt is provided.

The utility model solves the technological scheme that its technical problem adopted:

Chek bolt comprises the bolt matrix, it is characterized in that: the bolt head end of matrix, with the counterface of connected piece on be provided with the engagement line, make the friction between fitting surface become engagement.

On the basis of above-mentioned main technical schemes, can increase following further perfect technological scheme:

Described engagement line can be wavy continuous engagement burr for the circumferencial direction along counterface.

Described engagement line can be for along salient point that is uniformly distributed with on the circumferencial direction of counterface or concave point.

Be provided with Upper gasket successively on the described threaded stem that comprises the bolt matrix, spring, lower levelling plate, described engagement line is located on the counterface of Upper gasket and connected piece.

The beneficial effect of the utility model is the bolt head end of matrix, with the counterface of connected piece on be provided with the engagement line, making slides is difficult for producing; Even produced slip; As long as fastening force also exists, just can continue to have the effect of locking (cunning) in the engagement of next engagement place.

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Embodiment

As shown in Figure 1, the utility model chek bolt comprises bolt matrix 1; On the counterface of the bolt head end of matrix and connected piece, be provided with and be wavy continuous engagement line 2, describedly be the wavy regular engaging tooth that can preferably be arranged to gear shape continuously, make the friction between fitting surface become engagement along the circumferencial direction of counterface; As shown in Figure 2, on sliding door 7, be fixed with connecting body 6, be provided with a pad 5 in the connecting body; Pad 5 is provided with screw, and one of them bolt 1 passes screw, like Fig. 3 and shown in Figure 4; All be provided with the regular engaging tooth 2 of gear shape on the counterface of bolt head end and connected piece, make engagement between bolt 1 and the pad 5, the friction that becomes between fitting surface is engagement; Bolt 1 passes pad and is threaded with a slide block 4, in the straight line chute 3 that slide block 4 is installed, sliding door is moved along chute 3; Because the bolt head end matches with pad with the regular engaging tooth that the counterface of connected piece is provided with into gear shape, avoided sliding door in the process that straight line moves like this, bolt rotates; Cause the slip that cooperates of bolt and slide block, even cause and come off, even if produced slip between bolt and the slide block; Also can place and continue to slide, reach anti-skidding effect in the engagement of next engaging position.

As shown in Figure 5; Chek bolt; Comprise the bolt matrix, on the counterface of the bolt head end of matrix and connected piece, be provided with, but can be provided with concave point or the salient point that matches at the following fitting surface of pad also preliminary election when mounted simultaneously along salient point that is uniformly distributed with on the circumferencial direction of counterface or concave point; The counterface that formation can be meshed prevents bolt looseness.

As shown in Figure 6, the utility model chek bolt comprises bolt matrix 1; Be provided with Upper gasket 10 on the threaded stem of bolt matrix successively, spring 9, lower levelling plate 11; Upper gasket, spring, lower levelling plate make up as a whole, and described engagement line is located at the counterface of Upper gasket 10 and connected piece 8, on bolt 1 and lower levelling plate 11 counterfaces; This structural bolts can be utilized the elastic force of spring, remains counterface and keeps engagement, has avoided the loosening of bolt.
