Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fixed-torque assembly tools, and particularly relates to a fixed-torque assembly tool with an air-breaking straight handle and a swivel ring steering. Background Art
[0002] A pneumatic fixed-torque assembly tool is an assembly tool that uses compressed air as a power source and precisely controls torque through air pressure adjustment and mechanical structures. It can apply precise torque to fasteners such as bolts and nuts during the assembly process to ensure that the fasteners are correctly tightened to the predetermined torque value. This tool can also stop the rotating head in special cases through an air-breaking switch to avoid over-torque or under-torque situations and ensure the accuracy and consistency of the assembly.
[0003] Since the sizes and specifications of fasteners are diverse, including different screws, bolts, nuts, etc., each fastener has its specific size and torque requirements. To adapt to these different fasteners, the fixed-torque assembly tool must provide various sizes to ensure that the tool can correctly and effectively cooperate with the fasteners. Therefore, during the operation process, it is necessary to frequently replace the installation head of the assembly tool to meet different needs, which consumes a lot of time in this process.
[0004] In view of this, a fixed-torque assembly tool with an air-breaking straight handle and a swivel ring steering is proposed. Summary of the Utility Model
[0005] The purpose of the utility model is to solve the problem that the traditional fixed-torque assembly tool with an air-breaking straight handle and a swivel ring steering needs to frequently replace the installation head of the assembly tool, which consumes a lot of time, and to provide a fixed-torque assembly tool with an air-breaking straight handle and a swivel ring steering.
[0006] To solve the above technical problems, the utility model adopts the following technical scheme: A fixed-torque assembly tool with an air-breaking straight handle and a swivel ring steering, including a main body and a mounting plate fixedly connected to the bottom of the main body. An air inlet pipe is provided at the top of the main body. A rotating head is rotatably connected to the bottom of the main body. An air-breaking switch is provided on the main body.

[0007] Further, a slide bar is fixedly connected to the rotating rod, and a plurality of diagonal braces for fixing the mounting plate to the main body are fixedly connected to the mounting plate.
[0008] Further, two upper limit rods and two lower limit rods are fixedly connected to the rotating rod. The two upper limit rods and the two lower limit rods are symmetrically arranged. Two limit blocks are arranged between the upper limit rod and the lower limit rod. Both of the two limit blocks are slidably arranged on the main body. The distance between the limit block and the upper limit rod is the same as the distance between the limit block and the lower limit rod, and the distance between the limit block and the upper limit rod is the same as the thickness of the mounting disc.
[0009] Further, a locking rod is slidably arranged on the rotating rod. The bottom of the locking rod is arranged in an inclined plane. One end of each of the two limit blocks close to the locking rod is arranged in an inclined plane adapted to the bottom of the locking rod. The two limit blocks are elastically connected by a spring.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figure 1-7 .
[0024] The fixed-torque assembly tool with an air-cut-off straight handle and a swivel ring steering of the present utility model includes a main body 1 and a mounting plate 2 fixedly connected to the bottom of the main body 1. An air inlet pipe 11 is provided at the top of the main body 1, a rotating head 13 is rotatably connected to the bottom of the main body 1, an air cut-off switch 12 is provided on the main body 1, a plurality of transmission gears 6 are rotatably arranged in the mounting plate 2, the plurality of transmission gears 6 are connected by a tooth belt 7, a rotating rod 5 is slidably connected to each of the plurality of transmission gears 6, a mounting head 8 is fixedly connected to the bottom of each of the plurality of rotating rods 5, a driving gear 3 is fixedly connected to the rotating head 13, a driven gear 4 meshing with the driving gear 3 is slidably connected to the top of any one of the plurality of rotating rods 5, and the driven gear 4 is rotatably connected to the top of the mounting plate 2.
[0025] That is to say, when the main body 1 works, it will drive the rotating head 13 to rotate. At this time, the rotating head 13 drives the driving gear 3 to rotate, and then drives the plurality of rotating rods 5 to rotate through the connection of the transmission gears 6 and the tooth belt 7.
[0026] In addition, a slide bar 51 is fixedly connected to the rotating rod 5, and a plurality of diagonal braces 21 for fixing the mounting plate 2 to the main body 1 are fixedly connected to the mounting plate 2.
[0027] Among them, two upper limit rods 52 and two lower limit rods 53 are fixedly connected to the rotating rod 5. The two upper limit rods 52 and the two lower limit rods 53 are symmetrically arranged. Two limit blocks 9 are arranged between the upper limit rod 52 and the lower limit rod 53. The two limit blocks 9 are both slidably arranged on the main body 1. The distance between the limit block 9 and the upper limit rod 52 is the same as the distance between the limit block 9 and the lower limit rod 53, and the distance between the limit block 9 and the upper limit rod 52 is the same as the thickness of the mounting disc 2.
[0028] Secondly, a locking rod 10 is slidably arranged on the rotating rod 5. The bottom of the locking rod 10 is arranged in an inclined surface. One end of each of the two limit blocks 9 close to the locking rod 10 is arranged in an inclined surface adapted to the bottom of the locking rod 10. The two limit blocks 9 are elastically connected by a spring 114. The locking rod 10 is used to press down to make the two limit blocks 9 move outwards.
[0029] Specifically, a locking block 111 is fixedly connected to the top of the locking rod 10. A locking groove 112 with a size adapted to the locking block 111 is opened at the top of the rotating rod 5. A handle 113 is fixedly connected to the top of the locking rod 10.
[0030] When using this device, different mounting heads 8 are connected to different rotating rods 5. When the mounting head 8 needs to be used, rotate the handle 113 on the rotating rod 5 to contract the limit block 9, then press down the rotating rod 5, and then rotate the handle 113 to lock the locking rod 10 and the rotating rod 5. At this time, the limit block 9 and the upper limit rod 52 limit the rotating rod 5 and the mounting disc 2, and this mounting head 8 is lower than other mounting heads 8, which will not affect the normal use of the device.
[0031] It should be noted that as Figure 7 shown, the locking groove 112 is arranged with an L-shaped cross-section. That is to say, when pressing down the locking rod 10 and then rotating the locking rod 10, the locking rod 10 and the rotating rod 5 can be locked. When specifically setting, it should be noted that this rotation should not affect the limit rod as much as possible.
[0032] In addition, the rotating rod 5 is limited by the limit block 9 and the lower limit rod 53 in the unused state, and the used rotating rod 5 is limited by the limit block 9 and the upper limit rod 52. When the pressed rotating rod 5 works, other rotating rods 5 will also rotate idly. However, since the height of the working rotating rod 5 is lower, the mounting heads 8 of the idling rotating rods 5 will not affect the use of the device.
[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
