Screw-in type mushroom head cushion buckle

Abstract

A screw-in type mushroom head buffer cushion buckle comprises a mushroom head which comprises a conical surface section and a circular ring section which are integrally formed, and a spiral curved surface is arranged on the inclined surface of the conical surface section; a connecting plate; the connecting section is used for connecting the mushroom head and the connecting plate; wherein the mushroom head, the connecting section and the connecting plate are integrally formed, a groove is formed in the top of the conical surface section of the mushroom head and used for pre-storing deformation, the mushroom head and the mounting hole are guided and screwed in through the spiral curved surface by pressing the connecting plate, and extrusion force is reduced. During installation, the mushroom head is aligned with the installation hole, then the connecting plate is pressed, axial force borne by the mushroom head is converted into circumferential force through the spiral curved surface of the mushroom head, the circumferential force enables the mushroom head to be tightened and compressed in the circumferential direction, and then the circumferential size of the mushroom head is smaller than that of the installation hole till the circular ring section of the mushroom head penetrates through the installation hole. As the mushroom head enters through circumferential spiral sliding instead of circumferential interference and extrusion at the same time, the extrusion force does not need to be too large.

Description

Technical Field

[0001] The utility model relates to the technical field of mushroom head buckles, in particular to a screw-in type mushroom head buffer pad buckle. Background Art

[0002] When installing a conventional mushroom-head rubber buffer clip, the mushroom head is squeezed into the mounting hole by hard extrusion. During the extrusion, the surrounding surface of the mushroom head is squeezed into the mounting hole at the same time, which requires a lot of pressure. In many cases, a press is even required to press it in. This method can easily damage the mushroom head. Accordingly, the A dimension of the interference fit cannot be made very large, which further leads to the risk of the clip coming out during subsequent use.

[0003] For this purpose, we propose a screw-in mushroom head buffer buckle. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a screw-in mushroom head buffer pad buckle. By pressing the connecting plate, the axial force exerted on the mushroom head is converted into a circumferential force through its own spiral surface. The circumferential force tightens and compresses the mushroom head circumferentially, thereby making the circumferential size of the mushroom head smaller than the mounting hole until the circular segment of the mushroom head passes through the mounting hole. Since the mushroom head enters by circumferential spiral sliding rather than squeezing in simultaneously by circumferential interference, the extrusion force does not need to be too large.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A screw-in mushroom head buffer buckle, comprising:

[0007] The mushroom head comprises a cone segment and a circular ring segment formed in one piece, and a spiral surface is arranged on the inclined surface of the cone segment;

[0008] Connecting plate;

[0009] A connecting section, used for connecting the mushroom head and the connecting plate;

[0010] Among them, the mushroom head, the connecting section and the connecting plate are integrally formed. The materials of the mushroom head, the connecting section and the connecting plate are all rubber. The mushroom head is provided with a groove at the top of the conical section for pre-storing deformation. By pressing the connecting plate, the mushroom head and the mounting hole are screwed in through the spiral surface guide to reduce the extrusion force.

[0011] It is further characterized by:

[0012] An integrally formed extension plate is disposed at one end of the connection plate, and the extension plate extends toward one side of the mushroom head.

[0013] The circular ring segment is connected to the connecting segment, and the diameter of the connecting segment is smaller than the diameter of the circular ring segment.

[0014] The height of the extension plate is greater than the height of the connecting section.

[0015] The annular segment and the conical segment are integrally formed.

[0016] The bottom of the connecting plate is provided with a wave surface for buffering.

[0017] The beneficial effects of the utility model are as follows:

[0018] The utility model has a compact and reasonable structure and is easy to operate. When installing the buckle, the mushroom head is aligned with the mounting hole and then the connecting plate is pressed. The axial force received by the mushroom head is converted into a circumferential force through its own spiral curved surface. The circumferential force causes the mushroom head to be tightened and compressed circumferentially, thereby causing the circumferential size of the mushroom head to be smaller than the mounting hole until the annular segment of the mushroom head passes through the mounting hole. Since the mushroom head enters by circumferential spiral sliding rather than being squeezed in simultaneously by circumferential interference, the extrusion force does not need to be too large, and the mushroom head can be deformed toward the groove, thereby reducing the extrusion force, thereby making the diameter difference A of the annular segment and the radius of the connecting segment larger, thereby making the clamping force of the mushroom head larger after installation, making the mushroom head more firmly clamped, and resetting it through the spiral reaction force after screwing in. In this way, the size of the interference fit with the mounting hole can be made larger, and the risk of the mushroom head coming out is greatly reduced.

[0019] At the same time, the utility model also has the following advantages:

[0020] (1) By providing the groove, the mushroom head can be deformed toward the groove, thereby reducing the extrusion pressure, and the radius difference A between the diameter of the circular ring segment and the connecting segment can be made larger, thereby making the clamping force of the mushroom head larger after installation, making the mushroom head more firmly clamped.

[0021] (2) The diameter of the connecting section is smaller than the diameter of the circular ring section. After the mushroom head is installed, the installation is completed by clamping the installation hole with the circular ring section.

[0022] (3) A wave surface is provided at the bottom of the connecting plate to play a buffering role. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The specific implementation of the utility model is described below in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 5 As shown, a screw-in mushroom head buffer pad buckle includes a mushroom head 1, a connecting section 2 and a connecting plate 3. The mushroom head 1, the connecting section 2 and the connecting plate 3 are integrally formed, and the mushroom head 1 and the connecting plate 3 are connected by the connecting section 2.

[0031] An integrally formed extension plate 301 is disposed at one end of the connection plate 3 . The extension plate 301 extends toward one side of the mushroom head 1 . The height of the extension plate 301 is greater than the height of the connection section 2 .

[0032] The bottom of the mushroom head 1 is provided with a circular segment 102, which is connected to the connecting segment 2. The top of the mushroom head 1 is provided with a conical segment 101, and the inclined surface of the conical segment 101 is provided with a spiral surface 1011. When installing the buckle, the mushroom head 1 is aligned with the mounting hole, and then the connecting plate 3 is pressed. The axial force on the mushroom head 1 is converted into a circumferential force through its own spiral surface 1011. The circumferential force tightens and compresses the mushroom head 1 circumferentially, thereby making the circumferential size of the mushroom head 1 smaller than the mounting hole, until the circular segment 102 of the mushroom head 1 passes through the mounting hole. The mushroom head 1 is inserted into the installation hole by sliding in the circumferential spiral instead of being squeezed in by the circumferential interference fit. Therefore, the extrusion force does not need to be too large, and the mushroom head 1 can be deformed toward the groove 4, thereby reducing the extrusion force, and the diameter difference A of the annular segment 102 and the radius of the connecting segment 2 can be made larger, so that the clamping force of the mushroom head 1 after installation is greater, and the mushroom head 1 is clamped more firmly. After being screwed in, it is reset by the spiral reaction force, so that the size of the interference fit with the installation hole can be made larger, and the risk of the mushroom head coming out is greatly reduced.

[0033] The annular segment 102 and the conical segment 101 are integrally formed.

[0034] The diameter of the connecting section 2 is smaller than the diameter of the annular section 102. After the mushroom head 1 is installed, the annular section 102 is clamped into the mounting hole to complete the installation.

[0035] The mushroom head 1, the connecting section 2 and the connecting plate 3 are all made of rubber, so that the mushroom head 1 has a certain elasticity, which is convenient for the installation of the mushroom head 1.

[0036] The mushroom head 1 is provided with a groove 4 at the top of the conical surface section 101, and the bottom of the groove 4 is set in the connecting section 2. Through the pre-deformation of the groove 4, when the mushroom head 1 is rotated and squeezed into the groove 4, the mushroom head 1 can be deformed toward the groove 4, thereby reducing the squeezing force, and the radius difference A between the diameter of the annular section 102 and the connecting section 2 can be made larger, thereby making the clamping force of the mushroom head 1 greater after installation, making the mushroom head 1 clamped more firmly.

[0037] The bottom of the connecting plate 3 is provided with a wave surface to play a buffering role.

[0038] When installing the buckle, align the mushroom head 1 with the mounting hole, and then press the connecting plate 3. The axial force on the mushroom head 1 is converted into a circumferential force through its own spiral surface 1011. The circumferential force tightens and compresses the mushroom head 1 circumferentially, thereby making the circumferential size of the mushroom head 1 smaller than the mounting hole, until the annular segment 102 of the mushroom head 1 passes through the mounting hole. Since the mushroom head 1 enters by circumferential spiral sliding rather than circumferential interference fit at the same time, the extrusion force does not need to be too large, and the mushroom head 1 can be deformed toward the groove 4, thereby reducing the extrusion force, and the diameter difference A of the annular segment 102 and the radius of the connecting segment 2 can be made larger, thereby making the clamping force of the mushroom head 1 greater after installation, making the mushroom head 1 more firmly clamped, and reset by the spiral reaction force after screwing in, so that the size of the interference fit with the mounting hole can be made larger, and the risk of the mushroom head coming out is greatly reduced.
