Description
Technical Field
[0001] The utility model relates to the technical field of double-ended studs, in particular to a double-ended stud. Background Art
[0002] A stud is a connector widely used in the mechanical field. It has threads at both ends and a smooth rod in the middle. One end is screwed into the threaded hole of the connected part, and the other end is tightened with a nut to connect the two connected parts into one. This structure makes it very practical for connecting parts with large thickness and frequent disassembly. The stud can withstand large tension and pressure to ensure the firmness of the connection. Depending on the use environment, different materials are available, such as carbon steel, stainless steel, etc. In various mechanical equipment, automobiles, aerospace and many other industrial fields, studs play an indispensable connecting role and are of great significance to the normal operation of the equipment and the overall structural stability.
[0003] There are utility models in the prior art such as the one with publication number CN202926811U. The present utility model relates to the field of connectors, specifically a double-headed stud. The present utility model provides the following technical solutions: a double-headed stud, comprising a rod-shaped body, the rod-shaped body comprising connecting parts located at both axial ends of the rod-shaped body and a connecting part connecting the two connecting parts, the outer circumferences of the two connecting parts are respectively provided with threads, the connecting part is a columnar body, the outer circumference of which is in the shape of an arc, and a filling space is provided on the connecting part, and an elastic filling body is provided in the filling space. The above technical solution provides a double-headed stud with strong bearing force and simple structure, but during use, the length of the double-headed stud is difficult to adjust according to actual conditions, resulting in inflexible equipment and inconvenient use.
[0004] In order to solve the problem that the length of the stud bolts is difficult to adjust according to actual conditions during use, resulting in the equipment being inflexible and inconvenient to use, the existing technology adopts a method of replacing stud bolts of different models to solve the problem, but it increases the difficulty of operating the equipment, which in turn causes the problem of inconvenience in using the equipment. Utility Model Content
[0005] The purpose of the utility model is to solve the shortcomings in the prior art that the length of the stud is difficult to adjust according to actual conditions during use, resulting in inflexible equipment and inconvenience in use, and to propose a stud.
[0006] The bolt has a first end fixed to the side panel that is located adjacent to the first bolt and a second end fixed to the side panel that is located adjacent to the first bolt.
[0007] Preferably, the surface of the mounting frame is rotatably connected to a rocker, and the surface of the rocker is fixedly connected to a rotating block. By setting the rocker, the elastic force of the torsion spring is transmitted. When the rotating block is pressed to drive the push rod to disengage from the slide, and the rotating block is released after adjusting the position of the first stud, the torsion spring loses its restraint and generates elastic force. By squeezing the rocker, the rocker drives the rotating block and the push rod to rotate, allowing the push rod to abut against the slide again, thereby fixing the first stud and completing the fixing operation after the stud length is adjusted.
[0008] Preferably, a push rod is fixedly connected to the surface of the rotating block, and the push rod is engaged with the adjustment groove on the surface of the slide. By setting the push rod, the push rod plays a key role in adjusting the length of the stud. When the rotating block is pressed, the push rod disengages from the slide as the rotating block and the rocker move, releasing the restriction on the first stud, so that the first stud can be pulled freely to adjust the position. When the first stud is adjusted to the appropriate position, the torsion spring causes the rotating block and the push rod to rotate, and the push rod re-engages the slide, restricting the sliding of the first stud, thereby fixing the position of the first stud and completing the length adjustment process.
[0009] Preferably, a torsion spring is sleeved on the surface of the rocker arm, and the two ends of the torsion spring are fixedly connected to the rocker arm and the mounting bracket respectively. By providing the torsion spring, during the process of adjusting the length of the stud, when the rotating block is pressed to drive the push rod to disengage from the slide plate, and the rotating block is released after the position of the first stud is adjusted, the torsion spring loses its restraint and generates elastic force. This elastic force will squeeze the rocker arm, and then drive the rotating block and the push rod to rotate, so that the push rod abuts against the slide plate, thereby fixing the position of the first stud and preventing it from sliding, thereby completing the locking after the stud length is adjusted.
[0010] Preferably, a clamping device is provided on the upper surface of the first stud, and the clamping device includes a card block, which is fixedly connected to the first stud, and a circular hole is opened on the surface of the card block, and the inner wall of the circular hole of the card block is fixedly connected with a resistance ring, and the inner wall of the resistance ring is rotatably connected with a pull rod, and the surface of the pull rod is fixedly connected with a clamping rod. By providing the clamping device, after the nut is installed on the stud, the clamping rod is rotated to make it abut against the nut, and the resistance generated by the resistance ring is reduced to reduce the rotation of the clamping rod, thereby effectively clamping and reinforcing the nut, which can reduce the phenomenon of loosening and slipping of the nut and ensure the reliability of the entire connection structure.
[0011] Preferably, there are two clamping rods, and the two clamping rods are arranged in a mirror-symmetrical manner. By setting the clamping rods, the function of the clamping rods is to resist the nut when the nut is installed on the stud, and to generate resistance through the resistance ring to reduce the rotation of the clamping rod itself, thereby clamping and reinforcing the nut, thereby reducing the loosening and stripping of the nut, ensuring the stability of the connection structure between the stud and the nut, and ensuring the reliability of the entire connection device during use.
[0012] Preferably, the clamping rod is set in an "L" shape, and the inner wall of the resistance ring is provided with friction teeth. By setting the resistance ring, the function of the resistance ring is to generate resistance to reduce the rotation of the clamping rod when the clamping rod and the nut are in contact, thereby effectively clamping and reinforcing the nut. This can prevent the nut from loosening and slipping due to vibration during the operation of the equipment, ensure the stability of the connection between the stud and the nut, and then ensure the reliability of the entire connection structure and maintain the normal operation of the equipment.
[0013] Compared with the prior art, the advantages and positive effects of the present invention are:
[0014] After releasing the rotating block, the elastic force of the torsion spring causes the rocker to drive the rotating block and the push rod to rotate, and the push rod abuts the slide plate to fix the first stud, completing the length adjustment. This process is convenient and fast, can meet the specific requirements of the stud length in different connection scenarios, and ensure the accuracy and stability of the connection structure.

[0022] The specific configuration and functions of the adjusting device 3 and the clamping device 4 will be described in detail below.
[0023] The first stud 1 is fixedly connected to the second stud 2 by the adjusting device 31, and the first stud 1 is fixedly connected to the second stud 2 by the adjusting device 31. The first stud 1 is fixedly connected to the second stud 2 by the adjusting device 31. The first stud 1 is fixedly connected to the second stud 2 by the adjusting device 31. The first stud 1 is fixedly connected to the second stud 2 by the adjusting device 31. The first stud 1 is fixedly connected to the second stud 2 by the adjusting device 31. The first stud 1 is fixedly connected to the second stud 2 by the adjusting device 31.
[0024] Specifically, the surface of the mounting bracket 34 is rotatably connected to a rocker arm 36, and the surface of the rocker arm 36 is fixedly connected to a rotating block 35. By providing the rocker arm 36, the elastic force of the torsion spring 37 is transmitted. When the rotating block 35 is pressed to drive the push rod 33 to disengage from the slide plate 32, and the rotating block 35 is released after adjusting the position of the first stud 1, the torsion spring 37 loses its restraint and generates elastic force. By squeezing the rocker arm 36, the rocker arm 36 drives the rotating block 35 and the push rod 33 to rotate, allowing the push rod 33 to contact the slide plate 32 again, thereby fixing the first stud 1 and completing the fixing operation after the stud length is adjusted.
[0025] Specifically, a push rod 33 is fixedly connected to the surface of the rotating block 35, and the push rod 33 is engaged with the adjustment groove on the surface of the slide plate 32. By setting the push rod 33, the push rod 33 plays a key role in the process of adjusting the length of the stud. When the rotating block 35 is pressed, the push rod 33 moves with the rotating block 35 and the rocker 36 and disengages from the slide plate 32, releasing the restriction on the first stud 1, so that the first stud 1 can be pulled freely to adjust its position. When the first stud 1 is adjusted to the appropriate position, the torsion spring 37 causes the rotating block 35 and the push rod 33 to rotate, and the push rod 33 re-engages with the slide plate 32, restricting the sliding of the first stud 1, thereby fixing the position of the first stud 1 and completing the length adjustment process.
[0026] Specifically, a torsion spring 37 is sleeved on the surface of the rocker 36, and the two ends of the torsion spring 37 are fixedly connected to the rocker 36 and the mounting bracket 34 respectively. By providing the torsion spring 37, when the rotating block 35 is pressed to drive the push rod 33 to disengage from the slide 32 during the process of adjusting the length of the stud, and the rotating block 35 is released after the position of the first stud 1 is adjusted, the torsion spring 37 loses its restraint and generates an elastic force. This elastic force will squeeze the rocker 36, and then drive the rotating block 35 and the push rod 33 to rotate, so that the push rod 33 abuts against the slide 32, thereby fixing the position of the first stud 1 and preventing it from sliding, thereby completing the locking after the stud length is adjusted.
[0027] Specifically, a clamping device 4 is provided on the upper surface of the first stud 1, and the clamping device 4 includes a clamping block 42, which is fixedly connected to the first stud 1, and a circular hole is opened on the surface of the clamping block 42. The inner wall of the circular hole of the clamping block 42 is fixedly connected to a resistance ring 43, and the inner wall of the resistance ring 43 is rotatably connected to a pull rod 44, and the surface of the pull rod 44 is fixedly connected to the clamping rod 41.
[0028] In this embodiment: by providing a clamping device 4, after the nut is installed on the stud, the clamping rod 41 is rotated to make it abut against the nut, and the resistance generated by the resistance ring 43 is used to reduce the rotation of the clamping rod 41, thereby effectively clamping and reinforcing the nut, which can reduce the phenomenon of nut loosening and thread slipping, and ensure the reliability of the entire connection structure.
[0029] Specifically, there are two clamping rods 41 , and the two clamping rods 41 are arranged in a mirror-symmetrical manner.
[0030] In this embodiment: a clamping rod 41 is provided. The function of the clamping rod 41 is to resist the nut when the nut is installed on the stud, and to generate resistance through the resistance ring 43 to reduce the rotation of the clamping rod 41 itself, thereby clamping and reinforcing the nut, thereby reducing the loosening and stripping of the nut, ensuring the stability of the connection structure between the stud and the nut, and ensuring the reliability of the entire connection device during use.
[0031] Specifically, the clamping rod 41 is arranged in an "L" shape, and the inner wall of the resistance ring 43 is provided with friction teeth.
[0032] In this embodiment: a resistance ring 43 is provided. The function of the resistance ring 43 is to generate resistance when the clamping rod 41 is against the nut to reduce the rotation of the clamping rod 41, thereby effectively clamping and reinforcing the nut. This can prevent the nut from loosening and slipping due to vibration during the operation of the equipment, ensure the stability of the connection between the stud and the nut, and further ensure the reliability of the entire connection structure, and maintain the normal operation of the equipment.
[0033] Working principle: By setting the adjustment device 3 and the clamping device 4, when the length of the stud needs to be adjusted, the rotating block 35 is pressed to drive the push rod 33 to disengage from the slide 32, and the first stud 1 is pulled at this time. When the first stud 1 slides to the appropriate position, the rotating block 35 is released, and the torsion spring 37 loses its restraint and generates elastic force to squeeze the rocker 36 to drive the rotating block 35 and the push rod 33 to rotate. The push rod 33 contacts the slide 32. At this time, the first stud 1 is difficult to slide, and the device completes the adjustment. When the nut is installed on the stud, the rotating clamping rod 41 contacts the nut, and the resistance generated by the resistance ring 43 reduces the clamping rod 4 1 is rotated to clamp and reinforce the nut, reducing the situation of the nut loosening and stripping. By setting the utility model, the length of the stud is adjusted. By pressing the rotating block 35, the push rod 33 is separated from the slide plate 32, and the first stud 1 can be freely pulled to a suitable position. After loosening the rotating block 35, the elastic force of the torsion spring 37 causes the rocker 36 to drive the rotating block 35 and the push rod 33 to rotate, and the push rod 33 abuts the slide plate 32 to fix the first stud 1, completing the length adjustment. This process is convenient and fast, can meet the specific requirements of the stud length in different connection scenarios, and ensure the accuracy and stability of the connection structure.
