Description

Technical Field

[0001] This utility model relates to the field of fastening hardware technology, and in particular to a split-type fastener. Background Technology

[0002] Fasteners, as the name suggests, are hardware components used to connect and fix various mechanical parts. By connecting and fixing various mechanical parts, they form a stable whole to withstand external forces. As the most widely used basic mechanical connectors, they cover a very wide range of fields.

[0003] Currently, fasteners on the market have their specifications fixed during the initial production stage. This means that their screw section and control section can only be used with screw holes and tools of fixed specifications, resulting in significant limitations in their application. Utility Model Content

[0004] The technical problem this invention aims to solve is that fasteners currently on the market have their specifications fixed at the initial stage of production, and can only be used with screw holes and tools of fixed specifications, which greatly limits their application.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a split fastener, including a threaded assembly rod and a top control head, wherein the end face of the threaded assembly rod is provided with an internal hexagonal limiting groove, and the end face of the top control head is provided with an internal threaded assembly groove that cooperates with the threaded assembly rod.

[0006] The top control head consists of an upper control head, a lower control head, and a central spring.

[0007] The upper and lower control heads are symmetrically provided with built-in assembly slots that cooperate with the central spring on their adjacent surfaces.

[0008] The upper control head has an external hexagonal limiting block with an integrated structure that mates with the internal hexagonal limiting slot at the center of its built-in assembly slot.

[0009] The inner side of the built-in assembly slot has an internal limiting block with an integrated structure that cooperates with the central spring.

[0010] The upper control head and the lower control head have symmetrical arc-shaped control grooves on the outer side walls of their adjacent surfaces.

[0011] The beneficial effects of this utility model are:

[0012] (1) The present invention provides a split fastener consisting of a split-structure design threaded assembly rod and a top control head, which can switch between different specifications of threaded assembly rods and top control heads, greatly improving adaptability.

[0013] (2) The top control head also adopts a split structure layout, which can quickly control the installation and separation of the threaded assembly rod and the top control head, improve assembly stability, and make operation more convenient. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] Figure 2 This is a split diagram of the present invention. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Figure 1 and Figure 2 The split fastener shown includes a threaded assembly rod 1 and a top control head 2. The end face of the threaded assembly rod 1 is provided with an internal hexagonal limiting groove 3, and the end face of the top control head 2 is provided with an internal threaded assembly groove 4 that mates with the threaded assembly rod 1.

[0020] To facilitate control, the top control head 2 consists of an upper control head 21, a lower control head 22, and a central spring 23.

[0021] The upper control head 21 and the lower control head 22 are elastically assembled through a central spring 23.

[0022] In order to facilitate the storage and assembly of the central spring 23, the upper control head 21 and the lower control head 22 are symmetrically provided with built-in assembly slots 24 that cooperate with the central spring 23 on their adjacent surfaces.

[0023] To accommodate the insertion limit, the upper control head 21 has an external hexagonal limit block 25 at the center of its built-in assembly slot 24, which has an integrated structure that mates with the internal hexagonal limit slot 3.

[0024] The end of the threaded assembly rod 1 is screwed into the internal threaded assembly groove 4 and threadedly assembled with the lower control head 22. Then, the external hexagonal limiting block 25 inside the upper control head 21 is inserted into the internal hexagonal limiting groove 3 to limit the angle of the threaded assembly rod 1, thereby preventing the threaded assembly rod 1 from separating from the lower control head 22.

[0025] To improve the installation stability of the central spring 23, the inner side of the built-in mounting groove 24 has an internal limiting block 26 with an integrated structure that cooperates with the central spring 23.

[0026] To facilitate quick separation, arc-shaped control grooves 27 are symmetrically provided on the outer walls of adjacent surfaces of the upper control head 21 and the lower control head 22.

[0027] By inserting their fingers into the arc-shaped control groove 27, people can pull the upper control head 21 outward, thus separating the outer hexagonal limit block 25 from the inner hexagonal limit groove 3. At this point, the threaded assembly rod 1 can be rotated to separate it from the top control head 2.

[0028] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
