DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Regarding the foregoing and other technical contents, features and effects of the present utility model, they will be clearly presented in the following detailed description in conjunction with the attached Figures 1 to 5 embodiment. The structural contents mentioned in the following embodiments are all referenced to the accompanying drawings of the specification.

[0023] In the description of the present utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model.

[0024] The exemplary embodiments of the present utility model will be described below with reference to the drawings.

[0025] Embodiment 1, an oil pipe clamp applicable to an oil pipeline, comprising a first connecting arm 1 and a second connecting arm 2. Both the first connecting arm 1 and the second connecting arm 2 are arranged in an arc shape. The first connecting arm 1 and the second connecting arm 2 are made of a metal material. In this embodiment, the first connecting arm 1 and the second connecting arm 2 can be made of iron, copper or steel. When in use, the first connecting arm 1 and the second connecting arm 2 are respectively sleeved on both sides of the oil pipe, so that the arc-shaped first connecting arm 1 and the second connecting arm 2 are attached to the oil pipe. The second connecting arm 2 includes a support portion 21 and an adjustment portion 22 integrally formed. One end of the first connecting arm 1 is provided with an adjustment channel 5. The other end of the first connecting arm 1 is hinged to the support portion 21 through a pin shaft. The adjustment portion 22 is fixedly connected to the side of the support portion 21 away from the pin shaft. The adjustment portion 22 is slidably connected inside the adjustment channel 5. When in use, the first connecting arm 1 and the second connecting arm 2 are respectively sleeved on both sides of the oil pipe, and the support portion 21 is rotated to insert the adjustment portion 22 into the adjustment channel 5, thereby clamping the oil pipe;

[0026] On one side of the adjusting part 22, there is a ratchet wheel 6. The ratchet wheel 6 is provided with a plurality of teeth with a right-angled triangle cross-section. The ratchet wheel 6 is fixedly installed on the outside of the adjusting part 22. A lock 7 is rotatably connected to the first connecting arm 1. A pin shaft is fixedly installed on the first connecting arm 1. A rotating groove for rotatably connecting with the pin shaft is formed in the middle of the lock 7. The lock 7 is arranged above the adjusting channel 5. One end of the lock 7 is fixedly connected with a barb 8 that cooperates with the ratchet wheel 6. The cross-section of the barb 8 is set as a right-angled triangle. During use, the straight side of the barb 8 fits with the straight side of the teeth on the ratchet wheel 6, so that the barb 8 catches the ratchet wheel 6, thereby fixing the adjusting part 22 inside the adjusting channel 5. The barb 8 is installed on the side of the lock 7 close to the ratchet wheel 6. An elastic member is installed between the end of the lock 7 away from the barb 8 and the first connecting arm 1. The elastic member can be a spring 14 or a torsion spring. In this embodiment, the elastic member is a spring 14. One end of the spring 14 is installed at the end of the lock 7 away from the barb 8, and the other end of the spring 14 is fixedly installed on the first connecting arm 1. In the initial state, under the action of the spring 14, the end of the lock 7 away from the barb 8 is pushed away from the adjusting channel 5, so that the barb 8 is pushed towards the ratchet wheel 6, thereby making the barb 8 clamp the ratchet wheel 6. The sliding distance of the adjusting part 22 inside the adjusting channel 5 is adjusted according to the diameter of the oil pipe, so that the first connecting arm 1 and the second connecting arm 2 fix the oil pipe.

[0027] A control structure for controlling the lock 7 is arranged on the first connecting arm 1. In this embodiment, the control structure can be a clip. During use, the end of the lock 7 away from the barb 8 is clamped by the clip, and the spring 14 is compressed downward, so that the barb 8 is separated from the ratchet wheel 6, and the adjusting part 22 can be withdrawn from the inside of the adjusting channel 5, and the first connecting arm 1 and the second connecting arm 2 are separated, so that the first connecting arm 1 and the second connecting arm 2 can be removed from the oil pipe.

[0028] Embodiment 2: On the basis of Embodiment 1, this embodiment provides another control structure. The control structure includes a stopper 9. The stopper 9 is located above the adjusting channel 5. One end of the stopper 9 close to the lock 7 is rotatably connected with a control ring 10. A groove 11 that cooperates with the control ring 10 is arranged at the end of the lock 7 away from the barb 8.

[0029] During use, the groove 11 is pressed downward, so that the barb 8 swings away from the ratchet wheel 6. When the barb 8 is separated from the ratchet wheel 6, the adjusting part 22 can slide inside the adjusting channel 5, so as to clamp the oil pipe or remove it from the oil pipe; after pressing the groove 11 downward, the control ring 10 is rotated so that the control ring 10 is buckled inside the groove 11, so that the end of the lock 7 away from the barb 8 cannot swing away from the adjusting channel 5. After use, the control ring 10 is taken out of the groove 11, so that the barb 8 catches the ratchet wheel 6.

[0030] A limiting block 12 that cooperates with the control ring 10 is fixedly connected to the stopper 9. In the initial state, the control ring 10 is stuck on the limiting block 12 to prevent the control ring 10 from moving randomly.

[0031] Embodiment 3: On the basis of Embodiment 1, the thickness of the support portion 21 gradually decreases from the first connecting arm 1 to the adjusting portion 22, thereby reducing the material used for the support portion 21 and achieving lightweight while ensuring stability.

[0032] The cross-section of the support portion 21 is set as an I-shaped, and a plurality of through holes 13 are provided in the middle of the support portion 21, thereby further reducing the material used.

[0033] During specific implementation:

[0034] When it is necessary to fix the oil pipe, press down the groove 11, the barb 8 swings away from the ratchet 6, rotate the control ring 10 so that the control ring 10 is buckled inside the groove 11, so that the end of the locking device 7 away from the barb 8 cannot swing away from the adjusting channel 5. When the barb 8 is separated from the ratchet 6, the adjusting portion 22 can slide inside the adjusting channel 5, so as to sleeved the first connecting arm 1 and the second connecting arm 2 on the oil pipe. Take out the control ring 10 from inside the groove 11, and under the action of the spring 14, the barb 8 is stuck to the ratchet 6, so that the first connecting arm 1 and the second connecting arm 2 fix the oil pipe.

[0035] When it is necessary to remove the oil pipe from the oil pipe, press down the groove 11, the barb 8 swings away from the ratchet 6, rotate the control ring 10 so that the control ring 10 is buckled inside the groove 11, take out the adjusting portion 22 from inside the adjusting channel 5, and remove the first connecting arm 1 and the second connecting arm 2 from the oil pipe.

[0036] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the claims of this patent application.
