Description

Technical Field

[0001] The utility model relates to the technical field of T-shaped bolts, in particular to a T-shaped bolt with a tenon. Background Art

[0002] The T-bolt with a tenon is a specially designed bolt, usually used in structures or mechanical devices that require a more secure connection. The tenon of a T-bolt usually refers to the tenon at one end of the bolt, which is similar in shape to a tenon and is used to provide a more secure connection during installation. Due to the tenon design, the T-bolt can better prevent rotation and loosening during installation. Therefore, it is suitable for equipment or structures that need to be frequently disassembled and assembled, as well as occasions working in a vibrating environment.

[0003] Existing T-bolts with tenons use the tenons to prevent the bolts from falling out of the slots. However, the geometric shape of the tenons is not suitable for specific application scenarios and the structure is not stable enough. Utility Model Content

[0004] In order to make up for the above shortcomings, the present invention provides a T-bolt with a tenon, aiming to improve the problem that the geometric shape of the tenon of the existing T-bolt with a tenon is not suitable for specific application scenarios and the structure is not stable enough.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A T-bolt with a tenon comprises a bolt head, the lower surface of the bolt head is fixedly connected to a connecting block, the lower surface of the connecting block is fixedly connected to a triangular main diagonal brace tenon, the outer wall of the triangular main diagonal brace tenon is fixedly connected to a triangular secondary diagonal brace, the upper surface of the triangular secondary diagonal brace is fixedly connected to the lower surface of the connecting block, the lower surface of the bolt head is fixedly connected to a connecting column, and one end of the connecting column is fixedly connected to a screw segment.

[0007] Preferably, a friction strip is fixedly connected to the lower surface of the bolt head, and a mounting groove is slidably connected to the outer wall of the connecting column, and the outer wall of the friction strip fits with the inner wall of the mounting groove.

[0008] Preferably, a placement groove is provided on the inner wall of the installation groove, a first fixing groove is provided on the inner wall of the installation groove, and a second fixing groove is provided on the inner wall of the installation groove.

[0009] Preferably, the outer wall of the connecting block is slidably connected to the inner wall of the placement groove.

[0010] Preferably, the outer wall of the triangular main diagonal support tenon is slidably connected to the inner wall of the first fixing groove.

[0011] Preferably, the outer wall of the triangular secondary diagonal support is slidably connected to the inner wall of the second fixing groove.

[0012] The utility model has the following beneficial effects:

[0013] 1. In the present invention, the bolt head is placed in the installation groove and then rotated. When it is rotated to a horizontal position, the bolt head is moved downward to complete the pre-installation. The next step can then be performed. The design of the triangular main diagonal bracing tenon can provide a more secure connection during the bolt installation process and can effectively prevent the bolt from rotating or loosening due to external force or vibration after installation.

[0014] 2. In the present invention, the friction strip fixedly connected to the lower surface of the bolt head can increase the friction between the bolt head and the contact surface of the mounting groove. This additional friction can help stabilize the position of the bolt after installation and prevent loosening due to external force or vibration, thereby improving the reliability and safety of the connection.

[0020] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1The utility model provides an embodiment: a T-bolt with a tenon, comprising a bolt head 1, the lower surface of the bolt head 1 is fixedly connected to a connecting block 2, the lower surface of the connecting block 2 is fixedly connected to a triangular main diagonal brace tenon 3, the outer wall of the triangular main diagonal brace tenon 3 is fixedly connected to a triangular secondary diagonal brace 4, the upper surface of the triangular secondary diagonal brace 4 is fixedly connected to the lower surface of the connecting block 2, the lower surface of the bolt head 1 is fixedly connected to a connecting column 5, and one end of the connecting column 5 is fixedly connected to a screw segment 6;

[0022] Specifically, the screw segment 6 is the main body of the T-bolt, which is used to cooperate with the internal thread of the nut or the connected component. The connecting column 5 is used to connect the bolt head 1 and the screw segment 6, and can fix the screw segment 6. The bolt head 1 can fix the connecting block 2, and the connecting block 2 can fix the triangular main diagonal bracing tenon 3. The triangular main diagonal bracing tenon 3 is used to prevent the bolt from rotating or loosening due to external force or vibration after installation.

[0023] Reference Figure 1 The lower surface of the bolt head 1 is fixedly connected with a friction strip 7, the outer wall of the connecting column 5 is slidably connected with a mounting groove 8, and the outer wall of the friction strip 7 fits with the inner wall of the mounting groove 8;

[0024] Specifically, the friction strip 7 fixedly connected to the lower surface of the bolt head 1 can increase the friction between the contact surface of the bolt head 1 and the mounting groove 8. This additional friction can help stabilize the position of the bolt after installation.

[0025] Reference Figure 1 - Figure 3 The inner wall of the mounting groove 8 is provided with a placement groove 9, the inner wall of the mounting groove 8 is provided with a first fixing groove 10, and the inner wall of the mounting groove 8 is provided with a second fixing groove 11; the outer wall of the connecting block 2 is slidably connected to the inner wall of the placement groove 9; the outer wall of the triangular main diagonal brace tenon 3 is slidably connected to the inner wall of the first fixing groove 10; the outer wall of the triangular secondary diagonal brace 4 is slidably connected to the inner wall of the second fixing groove 11;
