DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0024] The following is combined with Figure 1-4 This application is described in further detail.

[0025] The present application embodiment discloses a pumping unit brake handle. Figure 1 , Figure 2 A pumping unit brake handle includes a brake tooth 1, a locking tooth 2 is rotatably connected to the brake tooth 1, and the brake tooth 1 and the locking tooth 2 can be relatively meshed, so that the position of the brake tooth 1 is locked by the locking tooth 2.

[0026] A control component 3 is provided on the locking tooth 2, and the control component 3 controls the engagement and disengagement of the locking tooth 2 and the brake tooth 1. When the locking tooth 2 is disengaged from the brake tooth 1, the position of the brake tooth 1 is rotated to make the locking tooth 2 relative to the different positions of the brake tooth 1, and the locking tooth 2 is controlled to engage with the brake tooth 1 again to brake.

[0027] The brake tooth 1 includes a connecting portion 11, which is rotatably connected to the control assembly 3. A tooth portion 12 is fixedly connected to the upper portion of the connecting portion 11. The tooth portion 12 is an arc-shaped structure, and the arc center of the tooth portion 12 and the hinge point of the connecting portion 11 and the control assembly 3 coincide with each other, so that the tooth portion 12 can rotate around the hinge point of the connecting portion 11 and the control assembly 3. One end of the tooth portion 12 is fixedly connected to the connecting portion 11, and the brake tooth 1 rotates counterclockwise.

[0028] The latching tooth portion 12 includes a connecting bottom portion 121 at the bottom, the connecting bottom portion 121 is an arc-shaped structure, and an action portion 122 is fixedly connected above the connecting bottom portion 121, and the action portion 122 is arranged along the arc-shaped structure of the connecting bottom portion 121. The action portion 122 is a latching tooth structure evenly arranged along the arc of the connecting bottom portion 121, and the latching tooth structure of the action portion 122 is fixedly connected to the connecting bottom portion 121.

[0029] The locking tooth 2 includes a first vertical surface 21 and a first inclined surface 22. The first vertical surface 21 is vertically arranged, and the first inclined surface 22 is inclined. The inclination direction of the first inclined surface 22 is gradually inclined downward along the rotation direction of the brake tooth 1. The first inclined surface 22 is located on the side of the first vertical surface 21 away from the rotation direction of the brake tooth 1.

[0030] The action portion 122 of the brake tooth 1 includes a second vertical surface 1221 arranged opposite to the first vertical surface 21 of the locking tooth 2. The second vertical surface 1221 is arranged along the radial direction of the arc line of the tooth portion 12. A second inclined surface 1222 is arranged on one side of the second vertical surface 1221. The second inclined surface 1222 is inclined, and the inclination direction of the second inclined surface 1222 is the same as the inclination direction of the first inclined surface 22.

[0031] When the control component 3 controls the locking tooth 2 to move downward, the first inclined surface 22 of the locking tooth 2 abuts against the second inclined surface 1222 of the brake tooth 1, and the first vertical surface 21 of the locking tooth 2 abuts against the second vertical surface 1221 of the brake tooth 1, thereby limiting the rotation of the brake tooth 1 in the counterclockwise direction through the locking tooth 2, thereby limiting the position of the brake tooth 1.

[0032] Reference Figure 1 , Figure 3 The control assembly 3 includes a vertically arranged hinged rod 31, and the connecting portion 11 of the brake latch 1 is rotatably connected to the side wall of the hinged rod 31. A first connecting rod 32 is rotatably connected to the hinged rod 31, and the center of the first connecting rod 32 is relatively connected to the hinged rod 31. A second connecting rod 33 is hingedly arranged at one end of the first connecting rod 32, and a third connecting rod 34 is hingedly arranged at one end of the first connecting rod 32 away from the second connecting rod 33.

[0033] One end of the second connecting rod 33 facing away from the first connecting rod 32 is hingedly arranged with the top end of the locking tooth 2. A guide block 331 is sleeved on the outer wall of the locking tooth 2, and the guide block 331 is fixedly connected to the locking tooth 2. The side of the guide block 331 close to the hinge rod 31 is slidably connected to the hinge rod 31, and the outer wall of the hinge rod 31 is an arc structure. The side wall of the guide block 331 that is relatively connected to the hinge rod 31 is an arc structure that is relatively adapted to the outer side of the hinge rod 31, and the hinge rod 31 forms a guide surface at the position of the arc structure of the guide block 331. Under the guidance of the guide surface, the guide block 331 can move along the height direction of the hinge rod 31, thereby driving the locking tooth 2 to move along the height direction.

[0034] An operating housing 35 is fixedly connected to the top of the hinge rod 31 relative to the third connecting rod 34. The operating housing 35 includes a first operating housing 351 and a second operating housing 352. The first operating housing 351 is fixedly connected to the hinge rod 31, and the second operating housing 352 is located at the top of the first operating housing 351 and is relatively fixedly connected. The second operating housing 352 is a cylindrical hollow shell, and the second operating housing 352 and the third connecting rod 34 are coaxially arranged.

[0035] Reference Figure 3 , Figure 4 The third connecting rod 34 includes an operating rod 341 located at the top, and a length rod 342 is hingedly provided at the bottom end of the operating rod 341, and the bottom end of the length rod 342 is hingedly connected to the first connecting rod 32. The operating rod 341 is located inside the second operating shell 352, and the two ends of the operating rod 341 extend from the top wall and the bottom wall of the second operating shell 352 respectively, and the operating rod 341 and the second operating shell 352 are slidably connected.

[0036] A spring 26 is coaxially arranged inside the second operating shell 352, and an operating rod 341 is coaxially fixedly connected to a pressing plate 343 inside the second operating shell 352. The pressing plate 343 is located above the spring 26, and the top end of the spring 26 abuts against the pressing plate 343, and the bottom end of the spring 26 abuts against the inner bottom wall of the second operating shell 352.

[0037] When the operating rod 341 is pushed downward, the operating rod 341 drives the pressure plate 343 to move downward, compressing the spring 26, and the operating rod 341 drives the length rod 342 to move downward, and the length rod 342 drives the first connecting rod 32 to rotate about the hinge point of the first connecting rod 32 and the hinge rod 31, lifting the second connecting rod 33 upward, driving the locking tooth 2 to move upward, and disengaging the locking tooth 2 from the brake tooth 1.

[0038] When the operating rod 341 is released, the spring 26 restores and pushes the pressure plate 343 to move upward, and the pressure plate 343 drives the operating rod 341 to move upward, and then drives the length rod 342 hinged to the operating rod 341 to move upward, so that the first connecting rod 32 rotates around the hinge point of the first connecting rod 32 and the hinged rod 31, and the second connecting rod 33 moves downward, driving the locking tooth 2 to move downward, and the locking tooth 2 engages with the brake tooth 1.
