Description

Technical Field

[0001] This utility model relates to the field of fasteners, and in particular to a positioning bolt and a connection structure having the same. Background Technology

[0002] Bolts, as a very common type of fastener, have come to play a crucial role in our industrial production.

[0003] Currently, there is a method for connecting rods by fixing bolts with insertion holes on the bolt heads. These insertion holes are used to insert rods. In the past, when connecting rods to bolt heads, positioning holes were set around the rods and bolt heads. After the rods were inserted into the insertion holes, pins were inserted into the positioning holes of both to fix and position the rods within the bolt heads. This connection structure not only makes the manufacturing process cumbersome, but also makes it difficult to disassemble after the pins and positioning holes are interference-fitted.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] Reference Figures 1 to 8 This utility model discloses a positioning bolt, comprising: a bolt head 100 and a bolt shank 200.

[0029] One end of the bolt head 100 is provided with an installation groove 110, and a locking structure 111 is provided in the installation groove 110. The installation groove 110 is used to insert the rod 400, and the locking structure 111 is used to lock the rod 400. The installation groove 110 is used to connect and install the rod 400. The locking structure 111 cooperates with the rod 400. The rod 400 is provided with a structure that cooperates with the locking structure 111. No other connecting structure is required. The rod 400 is located in the installation groove 110. Twisting the rod 400 makes the rod 400 cooperate with the locking structure 111, so that the rod 400 is positioned and fixed.

[0030] Bolt rod 200 is located at the other end of bolt head 100 and is used for external connection.

[0031] In some embodiments, refer to Figure 5 and Figure 8The locking structure 111 includes two arc-shaped recesses 111a on the inner circumferential wall of the mounting groove 110. The intersection of the two arc-shaped recesses 111a forms a locking and limiting part 111b. The rod 400 is inserted into the mounting groove 110 and rotates to tighten the locking and limiting part 111b. It can be understood that the arc-shaped recess 111a is composed of two arcs with different radii of curvature. The first arc has the same radius as the outer contour of the locking connector 410 and the two are tangent. The second arc... The arc is a circular arc with a continuously decreasing radius of curvature. During the rotation of the snap-fit ​​connector 410, as the radius of curvature of the second segment of the arc continuously decreases, the snap-fit ​​connector 410 will continuously lock with the arc-shaped recess 111a. When the snap-fit ​​connector 410 rotates to the locking limit part 111b, the snap-fit ​​connector 410 can no longer rotate and is locked. The radius of curvature of the second segment of the arc-shaped recess 111a can be changed according to the required degree of locking of the connector, thereby controlling the degree of locking of the snap-fit ​​connector 410.

[0032] In some embodiments, refer to Figure 5 and Figure 8 There are two arc-shaped recesses 111a, which are symmetrically arranged about the axis of the bolt head 100. The two arc-shaped recesses 111a also result in two locking limit parts 111b, which are also symmetrically arranged about the axis of the bolt head 100. This arrangement ensures that the locking force of the snap-fit ​​connector 410 is more uniform, preventing uneven locking force when the snap-fit ​​connector 410 is rotated for locking, thus achieving high locking efficiency and reliable locking. It is understood that there can also be more than two arc-shaped recesses 111a, with several arc-shaped recesses 111a symmetrically arranged about the axis of the bolt head 100. Furthermore, the shape of the snap-fit ​​connector 410 should change accordingly with the change in the number of arc-shaped recesses 111a.

[0033] In some embodiments, refer to Figure 5 and Figure 8 The mounting groove 110 has a first shaft and a second shaft. The length of the first shaft is greater than that of the second shaft. An arc-shaped recess 111a is formed on the inner wall of the mounting groove 110 where the second shaft is located. The setting that the lengths of the first shaft and the second shaft in the mounting groove are inconsistent provides the conditions for the setting of the arc-shaped recess 111a and the locking limit part 111b. It can be understood that when there are several arc-shaped recesses 111a, the number of the first shaft and the second shaft should change accordingly.

[0034] In some embodiments, the bolt head 100 and the bolt shank 200 are integrally formed. The integrally formed component has higher structural strength and stability, and the manufacturing efficiency of integral forming is higher, resulting in lower production costs and greater economic benefits.

[0035] It is understandable that the bolt rod 200 has threads, which is a standard design and will not be elaborated on further.

[0036] The second aspect of this embodiment also provides a connection structure, as shown in the reference. Figures 1 to 4 The device includes a positioning bolt according to the first aspect embodiment, a connecting plate 300 and a rod 400, a bolt rod 200 threadedly connected to the connecting plate 300, a snap-fit ​​connector 410 provided on the rod 400, the snap-fit ​​connector 410 inserted into the mounting groove 110, the snap-fit ​​connector 410 being rotated to tighten the locking limit part 111b, the snap-fit ​​connector 410 being provided with two symmetrical snap-fit ​​parts, the two snap-fit ​​parts being matched and connected with two arc-shaped recesses 111a, the connecting plate 300 being provided with threaded holes 310, the bolt rod 200 being connected to the connecting plate 300 through the threaded holes 310, it is understood that the number of snap-fit ​​parts varies according to the number of arc-shaped recesses 111a.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
