Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic wrenches, in particular to a lever-type auxiliary structure of a pneumatic wrench. Background Art

[0002] A pneumatic wrench, also known as a combination of a ratchet wrench and an electric tool, is primarily a tool that provides high torque output with minimal consumption. The pneumatic wrench rotates the sleeve, which in turn drives the wrench head connected to the sleeve to loosen or tighten bolts. Pneumatic wrenches are widely used in many industries, such as auto repair, heavy equipment maintenance, product assembly, and anywhere else high torque output is required.

[0003] Regarding the lever-type auxiliary structure of a pneumatic wrench, the national publication number CN213592748U discloses a "pneumatic wrench" in which a rotating rod drives a sliding block to move along a support plate away from the rotating rod, driving the rotating disk to rotate, causing the protrusion to slide in the sliding groove, thereby causing the fixed block to rotate, forming a channel for gas to pass through, allowing the pneumatic wrench to operate. This device is simple to use. Only the rotating rod needs to be pressed to rotate the fixed block to form a channel to drive the pneumatic wrench to operate. At the same time, the opening and closing of the channel reduces the output speed and directly transmits power, improving torque transmission, increasing the stability of the pneumatic wrench and improving work efficiency. However, in actual use, this pneumatic wrench still has certain defects. For example, when the pneumatic wrench is used to loosen or tighten a bolt, there is only one force point on the pneumatic wrench. When one hand holds the pneumatic wrench to rotate the bolt, it is easy to slip. In some narrow spaces, the other hand cannot reach into the pneumatic wrench to support and assist the operation, which affects the stability of the bolt tightening. Utility Model Content

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0025] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Example 1

[0027] like Figure 1-Figure 7As shown, a lever-type auxiliary structure of a pneumatic wrench includes: a pneumatic wrench 1, a connecting rod 101, a wrench head 102, a square head 103, an auxiliary rod 204, an auxiliary component and a suspension component, the connecting rod 101 is arranged at the top of the pneumatic wrench 1, the top of the connecting rod 101 is provided with a wrench head 102, the square head 103 is installed on one side of the outer end of the wrench head 102, the auxiliary rod 204 is arranged at the outer end of the connecting rod 101, the auxiliary component arranged at the outer end of the connecting rod 101, used to assist the pneumatic wrench 1 to rotate under force, and the suspension component arranged at one end of the auxiliary rod 204, used to suspend and carry the auxiliary rod 204.

[0028] Among them, reference Figure 1-Figure 2 A connecting tube 104 is provided at the bottom of the pneumatic wrench 1, a pressing strip 105 is movably connected to one side of the outer end of the pneumatic wrench 1, and a pressing switch 106 is movably connected between the pressing strip 105 and the pneumatic wrench 1.

[0029] When using the pneumatic wrench 1, connect the external air pipe to the connecting pipe 104, push the air pipe and the connecting pipe 104 firmly, and when the pneumatic wrench 1 needs to be started, grab the pneumatic wrench 1 with your hand and hold the pressing bar 105 firmly. When the pressing bar 105 is subjected to force, it will squeeze the pressing switch 106 back into the inside of the pneumatic wrench 1, thereby starting the pneumatic wrench 1. After releasing the pressing bar 105, the pressing switch 106 pops out from the inside of the pneumatic wrench 1, and the pneumatic wrench 1 can be turned off.

[0030] Among them, reference Figures 1-6 The auxiliary components include: a limiting cylinder 2 arranged at the outer end of the connecting rod 101, a support rod 201 installed inside the limiting cylinder 2, a connecting plate 202 installed on the support rod 201, a connecting sleeve 203 arranged at the outer end of the limiting cylinder 2, and the top side of the connecting sleeve 203 is welded to the auxiliary rod 204.

[0031] When using the pneumatic wrench 1 to loosen or tighten a bolt, the square head 103 of the pneumatic wrench 1 is sleeved on the outside of the bolt, the pressing bar 105 is grasped and the pressing switch 106 is pressed to start the pneumatic wrench 1. The pneumatic motor inside the pneumatic wrench 1 drives the square head 103 to rotate, which is convenient for loosening or tightening the bolt. When one hand holds the pneumatic wrench 1 to rotate the bolt, the other hand grasps the auxiliary rod 204 to put the connecting sleeve 203 into the limiting cylinder 2, so that the connecting sleeve 203 is stuck in the connecting disk 202, and the other end of the pneumatic wrench 1 is supported and stressed. There are two force points on the pneumatic wrench 1 to assist in loosening or tightening the bolt, which avoids slipping when holding the pneumatic wrench 1 to rotate the bolt. In addition, in a narrow space, the pneumatic wrench 1 can be used for auxiliary support operations, thereby improving the stability of bolt tightening.

[0032] Among them, reference Figure 1The limiting cylinder 2 is set as a short cylinder structure, the connecting sleeve 203 is set as a long cylinder structure, and the inner diameter of the limiting cylinder 2 is larger than the diameter of the connecting sleeve 203. During the use of the connecting sleeve 203, after the connecting sleeve 203 is placed inside the limiting cylinder 2, the connecting sleeve 203 and the connecting disk 202 are clamped and connected. A gap is left between the connecting sleeve 203 and the limiting cylinder 2 to facilitate the movement of the connecting sleeve 203, and the connecting sleeve 203 is set as a long cylinder structure, and the connecting sleeve 203 protrudes toward the outside of the pneumatic wrench 1, so that a gap is left between the auxiliary rod 204 and the pneumatic wrench 1 to prevent the auxiliary rod 204 from hitting the pneumatic wrench 1 during use.

[0033] Among them, reference Figure 1 and Figure 5 The connecting sleeve 203 and the auxiliary rod 204 are both made of aluminum alloy material. During use, the connecting sleeve 203 and the auxiliary rod 204 are made of aluminum alloy material, which makes the connecting sleeve 203 and the auxiliary rod 204 have good firmness and lightness, easy to carry, and avoid being too heavy when used. In addition, the aluminum alloy material has low cost and is easy to obtain.

[0034] Among them, reference Figure 3 、 Figure 4 and Figure 6 The outer ring of the connecting disk 202 is equipped with several teeth 205, and the inner side of the connecting sleeve 203 is provided with several tooth grooves 206, and the tooth grooves 206 are engaged with the teeth 205. When the connecting sleeve 203 is inserted into the connecting disk 202, the tooth grooves 206 inside the connecting sleeve 203 will be pressed against the teeth 205 on the outer ring of the connecting disk 202, so that the connecting sleeve 203 and the connecting disk 202 are firmly connected, preventing the connecting sleeve 203 and the connecting disk 202 from sliding when the auxiliary rod 204 is bent.

[0035] After the connecting sleeve 203 is pulled out from the limiting cylinder 2, the teeth 205 are aligned with the tooth groove 206 and snapped into place, so that the connecting sleeve 203 can be placed at different angles outside the pneumatic wrench 1 and the position can be adjusted according to the needs of the user.

[0037] Based on Example 1, Figure 1 、 Figure 2 and Figure 7 The suspension assembly includes: a through hole 3 opened at the bottom of the auxiliary rod 204, a hanging ring 301 is provided inside the through hole 3, a buckle 302 is provided on the hanging ring 301, and a buckle 303 is provided on the buckle 302.

[0038] When the auxiliary rod 204 is in use, the ring 301 is installed inside the through hole 3, and the buckle 302 is installed on the ring 301, so that the buckle 303 and the auxiliary rod 204 are used as an integrated whole. When the auxiliary rod 204 is used, it can be buckled on the belt through the buckle 303, and the auxiliary rod 204 can be hung and carried, so that the purpose of holding and using it is achieved, which is convenient and quick.

[0039] Among them, reference Figure 1 、 Figure 2 and Figure 7 The auxiliary rod 204 is provided with an anti-slip sleeve 207, and the surface of the anti-slip sleeve 207 is provided with several anti-slip stripes, and the anti-slip sleeve 207 is made of rubber material. When the auxiliary rod 204 is in use, grabbing the anti-slip sleeve 207 with the hand can increase the friction between the auxiliary rod 204 and the hand, preventing the auxiliary rod 204 and the hand from slipping, and thus can help support the pneumatic wrench 1 firmly.

[0040] The device can support the other end of the pneumatic wrench 1 with force through the auxiliary component, and has two force points on the pneumatic wrench 1 to assist in loosening or tightening the bolt, thereby preventing the pneumatic wrench 1 from slipping when turning the bolt. In addition, the pneumatic wrench 1 can be assisted and supported in a narrow space, thereby improving the stability of bolt tightening. The auxiliary rod 204 can be hung and carried through the hanging component, so that it can be used at the same time, which is convenient and quick. Specific implementation method: When using the pneumatic wrench 1 to loosen or tighten a bolt, the square head 103 of the pneumatic wrench 1 is put on the outside of the bolt, the pressing bar 105 is grasped and the pressing switch 106 is pressed to start the pneumatic wrench 1. The pneumatic motor inside the pneumatic wrench 1 drives the square head 103 to rotate, which is convenient for loosening or tightening the bolt. When one hand holds the pneumatic wrench 1 to rotate the bolt, the other hand grasps the auxiliary rod 204 to put the connecting sleeve 203 into the limiting cylinder 2, so that the connecting sleeve 203 is stuck in the connecting disk 202, and the other end of the pneumatic wrench 1 is supported and stressed. There are two force points on the pneumatic wrench 1 to assist in loosening or tightening the bolt, which avoids slipping when holding the pneumatic wrench 1 to rotate the bolt, and in a small space, the pneumatic wrench 1 can be assisted and supported to improve the stability of bolt tightening.

[0041] When the auxiliary rod 204 is in use, the ring 301 is installed inside the through hole 3, and the buckle 302 is installed on the ring 301, so that the buckle 303 and the auxiliary rod 204 are used as an integrated whole. When the auxiliary rod 204 is used, it can be buckled on the belt through the buckle 303, and the auxiliary rod 204 can be hung and carried, so that the purpose of holding and using it is achieved, which is convenient and quick.
