Through adopting above-mentioned technical scheme, when the screw sleeve pipe body locks on the article, the antislip strip on the countersunk head can further avoid the screw sleeve pipe body to rotate to prevent that the screw sleeve pipe body is not hard up.
Furthermore, a plurality of abutting holes are formed in the upper surface of the countersunk head and surround the positioning groove.
Through adopting above-mentioned technical scheme, support the setting in tight hole, can exert the effort to the screw sleeve pipe body through supporting tight hole under the circumstances that the constant head tank damaged to make things convenient for the screw sleeve pipe body to rotate and take out.
Furthermore, the cross section of the positioning groove is hexagonal.
Through adopting above-mentioned technical scheme, the cross-section of constant head tank is the hexagon setting, the processing of the constant head tank of being convenient for, and the effect instrument is comparatively common.
Furthermore, the inside wall of constant head tank is provided with a plurality of locating holes.
Through adopting above-mentioned technical scheme, the effort can further be exerted to the screw sleeve pipe body through the locating hole under the condition that the constant head tank damaged to the setting of locating hole to make things convenient for the screw sleeve pipe body to rotate and take out.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) after the screw and the screw sleeve are locked, the screw applies acting force to the elastic sheet to enable the abutting block to be embedded into an object, so that the screw sleeve body and the object are firmly fixed, and the purpose of preventing the screw sleeve from loosening is achieved;
(2) a plurality of through grooves, elastic pieces and abutting blocks are arranged along the peripheral side of the screw sleeve body, so that the acting force of the screw sleeve body on an object can be increased, and the screw sleeve body is firmly fixed with the object;
(3) the screw sleeve body can be further prevented from rotating through the anti-slip strip on the countersunk head, so that the screw sleeve body is prevented from loosening.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
The utility model provides a screw sleeve structure, as shown in fig. 1, 2, includes screw sleeve body 1, and 1 one end of screw sleeve body is fixed with countersunk head 2 that has constant head tank 3, and the inside of screw sleeve body 1 is made internal thread and external screw thread respectively with the outside, set up on the lateral wall of screw sleeve body 1 rather than the communicating logical groove 4 in inside, lead to and extend flexible piece 5 on the groove 4 lateral wall, and flexible piece 5 is fixed with to the one side of screw sleeve body 1 outer wall and supports tight piece 6.
As shown in fig. 1 and 2, a plurality of through grooves 4, elastic pieces 5 and abutting blocks 6 are formed along the circumferential side of the screw grommet body 1. Through leading to groove 4, flexure strip 5 and support tight piece 6 along 1 week side preparation of screw sleeve pipe body have a plurality of, can increase the effort that screw sleeve pipe body 1 applyed the article to make screw sleeve pipe body 1 firmly fixed mutually with the article.
Furthermore, the abutting blocks 6 are arranged in an arc shape. When the abutting block 6 is embedded into the object, the abutting block 6 is arranged in an arc shape, so that the abutting block 6 can be embedded into the object conveniently, and the stress area between the abutting block 6 and the object is increased.
It should be noted that, in order to increase the roughness of the surface of the abutting block 6, thereby increasing the acting force between the abutting block 6 and the object, the surface of the abutting block 6 is frosted in this embodiment.
As shown in fig. 1 and 2, the side wall of the countersunk head 2 is inclined, the lower end of the inclined surface of the screw sleeve body 1 faces the center of the end far away from the countersunk head 2, and a plurality of anti-slip strips 7 extend on the inclined surface of the countersunk head 2. When the screw sleeve body 1 is locked on an object, the anti-slip strip 7 on the countersunk head 2 can further prevent the screw sleeve body 1 from rotating, so that the screw sleeve body 1 is prevented from loosening.
Further, the upper surface of countersunk head 2 just encircles constant head tank 3 and has seted up six and support tight hole 8, can exert the effort to screw sleeve pipe body 1 through supporting tight hole 8 under the condition that constant head tank 3 damaged to make things convenient for screw sleeve pipe body 1 to rotate and take out.
As shown in fig. 1 and 2, the cross-section of the positioning groove 3 is hexagonal, which facilitates the processing of the positioning groove 3, and the action tools are common.
Further, six locating holes have been seted up to the inside wall of constant head tank 3, can further exert the effort to screw sleeve pipe body 1 through the locating hole under the condition that constant head tank 3 damaged to make things convenient for screw sleeve pipe body 1 to rotate and take out.
The utility model discloses a working process and beneficial effect as follows: when the screw sleeve is required to be locked on an object, the positioning groove 3 on the countersunk head 2 is acted by a tool firstly, so that the screw sleeve body 1 is locked on the object through external threads, then the screw is locked through the internal threads inside the screw sleeve body 1, the screw applies acting force to the elastic sheet 5, and the abutting block 6 is embedded in the object.
In conclusion, compared with the simple locking by means of the external threads of the screw sleeve, the screw and the screw sleeve are locked, the elastic piece 5 is applied with acting force by the screw to enable the abutting block 6 to be embedded into the object, so that the screw sleeve body 1 is firmly fixed with the object, and the purpose of preventing the screw sleeve from loosening is achieved.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
