Detailed Description
The present invention will be described in further detail with reference to the following embodiments shown in the drawings.
Example 1.
Referring to fig. 1-2, a head positioning rivet nut comprises a positioning cylinder 1, a deformation cylinder 2 and a thread cylinder 3 which are connected in sequence, wherein the outer diameter of the positioning cylinder 1 is larger than that of the deformation cylinder 2, the thread cylinder 3 is provided with internal threads, two connected plates respectively abut against two end faces of the positioning cylinder 1 during use, and the distance between the two connected plates is positioned by selecting the axial length of the positioning cylinder 1.
For ease of understanding, referring to fig. 3, the first plate 51 and the second plate 52 are now positioned to maintain a certain distance therebetween. The head positioning rivet nut of the embodiment is used, the head positioning rivet nut is firstly penetrated into the first plate 51 and riveted on the first plate 51, then the second plate 52 is close to the positioning cylinder 1, the common screw 6 is used for penetrating through the second plate 52 and the positioning cylinder 1 and then is in threaded connection with the threaded cylinder 3, so that the second plate 52 and the positioning cylinder 1 are fixedly connected, and because the two plates are supported by the positioning cylinder 1, the axial length of the positioning cylinder 1 is the distance between the two plates. From this, the location of two plates can easily be realized to the head location rivet nut of using this embodiment. In particular, the axial length of the positioning cylinder 1 can be designed by those skilled in the art according to the actual positioning requirement.
Example 2.
Referring to fig. 4-5, in this embodiment, on the basis of embodiment 1, the outer wall of the deformation cylinder 2 is provided with a sealing groove 21, and the sealing ring 4 is sleeved on the sealing groove 21. The outer wall of the deformation cylinder 2 is provided with a sealing groove 21 which can be used for installing the sealing ring 4, and after the sealing ring 4 is riveted, the sealing ring 4 is tightly attached to the first plate 51, so that the sealing effect can be ensured.
Further, the sealing ring 4 is a rubber sealing ring.
Further, the distance from one side wall of the sealing groove 21 close to the positioning cylinder 1 is smaller than the thickness of the connected plate, the distance from one side wall of the sealing groove 21 far from the positioning cylinder 1 to the positioning cylinder 1 is greater than the thickness of the connected plate, and the width of the sealing ring 4 is equal to the width of the sealing groove 21. Therefore, after the threaded cylinder 3 and the deformation cylinder 2 of the head positioning rivet nut penetrate through the first plate 51, part of the sealing ring 4 is arranged in the through hole of the first plate 51, and part of the sealing ring is arranged outside the through hole, after the head positioning rivet nut is riveted, the part of the sealing ring 4 which is arranged outside the through hole is extruded and expanded by the expanded deformation cylinder 2, at the moment, part of the sealing ring 4 is abutted against the inner wall of the through hole, and part of the sealing ring is abutted against the surface of the first plate 51, so that the attaching tightness of the sealing ring 4 and the first plate 51 can be enhanced, and the sealing effect is improved. In addition, the seal ring 4 can also play a role in increasing friction and preventing the head positioning rivet nut from rotating relative to the first plate 51.
Further, the sealing groove 21 and the sealing ring 4 are fixed by adhesive. The sealing ring 4 is tightly adhered and fixed on the sealing groove 21, so that the sealing effect and the rotation prevention effect can be further improved.
The above mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention should not be limited thereby, that is, all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still included in the scope of the present invention.
