Description

Technical field:

[0001] The utility model relates to the technical field of fastener structures, in particular to a force-enhancing rotating bolt. Background technology:

[0002] Bolts are a common mechanical fastener, usually composed of a screw and a nut, used to connect two or more parts together to form a whole. The basic working principle of a bolt is to achieve the fastening and connection of parts through the threaded fit between the screw and the nut. Bolts are widely used in machinery manufacturing, construction engineering, automobile industry, electronic equipment and other fields. Almost all occasions that require connection and fixation cannot do without the use of bolts. Of course, screws and nuts can also be used separately. It is common to lock and fix the parts by pressing the screw against them. When bolts are used normally, tools are often needed to ensure locking. For the connection parts that need to be frequently disassembled and assembled, tools need to be carried, and it is often difficult to complete strong fastening with bare hands. For example, a T-bolt with a Chinese patent application number of 201620807976.4 has a special structure of the head 1 in the technical solution disclosed in the patent, which is poor in versatility and inconvenient for users to twist, resulting in reduced practicality.

[0003] In view of this, the inventor proposes the following technical solution. Utility model content:

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a force-enhancing rotating bolt.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a force-enhancing rotating bolt, comprising: a screw body, a push block that can slide out is provided on one side of the head of the screw body, and the force arm is increased by extending the push block out of the screw body, and the push block is limited by a locking pin.

[0006] Furthermore, in the above technical solution, a plurality of protrusions for applying force are arranged around the head of the screw body, and the push block is located at one of the protrusions.

[0007] Furthermore, in the above technical solution, the portion of the push block extending out of the screw body protrudes upward from the upper end surface of the screw body.

[0008] Furthermore, in the above technical solution, the push block is T-shaped, one end of the push block is inserted into the screw body, and the other end of the push block can be attached to the outer wall of the screw body and evenly distributed on the periphery of the screw body with intervals from the convex portion.

[0009] Furthermore, in the above technical solution, the head of the screw body is provided with a slide slot hole for telescopic insertion of the push block, and the head of the screw body is also provided with a limiting hole perpendicular to the slide slot hole and used to install a bayonet, and the limiting hole extends to communicate with the slide slot hole.

[0010] Furthermore, in the above technical solution, a travel groove for inserting a latch pin and enabling relative sliding is provided on one side of the push block.

[0011] Furthermore, in the above technical solution, the bayonet is a Kimi screw, and the maximum sliding stroke of the end of the bayonet in the stroke groove is 5 mm.

[0012] Furthermore, in the above technical solution, a spring for increasing friction is arranged between the push block and the screw body, and a positioning hole for positioning and installing the spring is arranged on the push block, one end of the spring is located in the positioning hole, and the other end of the spring is pressed against the inner wall of the screw body.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0014] 1. The utility model adopts a push block that can be slidably extended at the head of the screw body. When the screw body needs to be twisted and rotated, the push block is pushed out of the screw body, thereby increasing the length of the screw body rotation force arm, thereby achieving a labor-saving effect. Secondly, a bayonet is used to pass through the head of the screw body to limit the push block, so as to prevent the push block from falling off the screw body during use, and to avoid the screw body and the push block from being separated during transportation and use. In addition, the use of the bayonet for limiting can facilitate the replacement of the push block, and the practicality is increased by replacing push blocks of different lengths.

[0015] 2. In the utility model, a spring is added on one side of the push block to contact and press against the inner wall of the screw body, thereby increasing the relative sliding friction between the push block and the screw body, so that the push block always maintains a constant force during the pushing and pulling process, and the spring can be used to maintain the length of the push block extending out of the screw body, preventing the push block from retracting during the rotation of the screw body and affecting the use.

[0022] See Figures 1 to 5 As shown, a force-enhancing rotating bolt comprises: a screw body 1, a push block 2 that can slide out is provided on one side of the head of the screw body 1, and the force arm is increased by extending the push block 2 out of the screw body 1, and the push block 2 is limited by a bayonet 3. The push block 2 that can slide out is provided at the head of the screw body 1. When the screw body 1 needs to be turned and rotated, the push block 2 is pushed out of the screw body 1, thereby increasing the length of the rotating force arm of the screw body 1, thereby achieving a labor-saving effect. Secondly, the bayonet 3 is used to pass through the head of the screw body 1 to limit the push block 2, so as to prevent the push block 2 from falling off the screw body 1 during use, and to avoid the screw body 1 and the push block 2 from being separated during transportation and use. In addition, the bayonet 3 is used for limiting, so that the push block 2 can be easily replaced, and the practicality can be increased by replacing the push blocks 2 of different lengths.

[0023] The head of the screw body 1 is provided with a plurality of protrusions 11 for applying force, and the push block 2 is located at one of the protrusions 11. By evenly providing a plurality of protrusions 11 around the head of the screw body 1, when the screw body 1 is rotated by hand, the protrusions 11 can greatly increase the convenience of applying force, making it convenient to rotate the screw body 1.

[0024] The push block 2 is T-shaped, one end of the push block 2 is inserted into the screw body 1, and the other end of the push block 2 can be attached to the outer wall of the screw body 1 and evenly spaced from the convex portion 11 and distributed on the periphery of the screw body 1. The portion of the push block 2 extending out of the screw body 1 protrudes upward from the upper end surface of the screw body 1. The end of the push block 2 is arranged to protrude from the upper end surface of the screw body 1, so that the user can easily push the push block 2 out when using it.

[0025] The head of the screw body 1 is provided with a slide slot hole 12 for the push block 2 to be telescopically inserted. The head of the screw body 1 is also provided with a limiting hole 13 perpendicular to the slide slot hole 12 and used to install the bayonet 3. The limiting hole 13 extends to communicate with the slide slot hole 12.

[0026] One side of the push block 2 is provided with a travel groove 21 for inserting and relatively sliding the bayonet 3. The bayonet 3 is a base screw, and the maximum sliding stroke of the end of the bayonet 3 in the travel groove 21 is 5mm.

[0027] A spring 4 for increasing friction is provided between the push block 2 and the screw body 1. A positioning hole 22 for positioning and installing the spring 4 is provided on the push block 2. One end of the spring 4 is located in the positioning hole 22, and the other end of the spring 4 is pressed against the inner wall of the screw body 1. The spring 4 is provided on one side of the push block 2 to contact and press against the inner wall of the screw body 1, thereby increasing the friction of relative sliding between the push block 2 and the screw body 1, so that the push block 2 always maintains a constant force during the pushing and pulling process, and the spring 4 can maintain the length of the push block 2 extending out of the screw body 1, so as to prevent the push block 2 from retracting during the rotation of the screw body 1 and affecting the use.

[0028] In summary, in the present invention, the spring 4 is installed on the push block 2 and inserted into the slide slot hole 12 of the screw body 1 together with the push block 2, and then the bayonet 3 is inserted from the limiting hole 13 to press into the travel slot 21 of the push block 2 to realize the assembly of the push block 2 and the screw body 1. The bayonet 3 limits the push block 2 so that the push block 2 can adjust the length of the screw body 1 within 5mm, and the spring 4 can increase the friction between the push block 2 and the screw body 1, so that the push block 2 maintains constant force during the push-pull process and can stay stably in a suitable position to prevent the push block 2 from sliding when the screw body 1 is twisted. When in use, the threaded portion of the screw body 1 is twisted into the corresponding threaded hole, and the push block 2 is pushed out of the slide slot hole 12 of the screw body 1, thereby extending the force arm length of the twisted screw body 1, thereby relatively increasing the force of the twisted screw body 1, and achieving a labor-saving effect.
