[0026] Please refer to Figures 1 to 3 a locking structure of a dust suction pipe shown in an embodiment of the present application. The locking structure of the dust suction pipe includes a first pipe body 1, a second pipe body 2, and a locking assembly 3.

[0027] A receiving cavity is formed inside the first pipe body 1. The second pipe body 2 is inserted into the first pipe body 1, and a sealed dust suction channel is formed between the second pipe body 2 and the first pipe body 1. The second pipe body 2 is driven to move inside the first pipe body 1 along the axial direction to adjust the total length of the dust suction pipe, so as to adapt to the requirements of different working environments.

[0028] The locking assembly 3 includes a locking member arranged at the end of the first pipe body 1 and a locking groove 331 extending along the axial direction of the second pipe body 2. The locking groove 331 includes a plurality of positioning grooves arranged at intervals along the axial direction of the second pipe body 2 and a movable groove 332 communicating with the plurality of positioning grooves. The width of the positioning groove is greater than the width of the movable groove 332. An active part 342 and a locking part 341 adapted to the widths of the movable groove 332 and the positioning groove are formed on the locking member. The locking member is configured to partially move radially so that the active part 342 cooperates with the movable groove 332 or the locking part 341 cooperates with the positioning groove to unlock or lock the relative positions of the first pipe body 1 and the second pipe body 2. When the locking member is driven by an external force to move so that the active part 342 cooperates with the movable groove 332, by moving the second pipe body 2, the active part 342 can be moved along the movable groove 332 into another positioning groove, thereby adjusting the length of the dust suction pipe. When the locking part 341 cooperates with the positioning groove by an external force, the length of the dust suction pipe can be locked.

[0029] In this embodiment, the second pipe body 2 includes two sleeved inner pipe body 22 and outer pipe body 21. An active cavity is formed between the inner pipe body 22 and the outer pipe body 21. The locking groove 331 is formed on the outer pipe body 21. The outer pipe body 21 and the inner pipe body 22 are eccentrically arranged. The outer pipe body 21 is cylindrical, and the inner pipe body 22 is semi-cylindrical and its end is connected to the inner wall of the outer casing 31. A crescent-shaped active cavity is formed between the inner pipe body 22 and the outer pipe body 21. The locking member is arranged at the place where the distance between the outer casing 31 and the inner casing 31 is the largest, which is convenient for the radial movement of the locking member of the second pipe body 2, and enables a sealed dust suction channel to be formed between the inner pipe body 22 of the second pipe body 2 and the first pipe body 1, facilitating dust suction operation. At the same time, the overall strength of the dust suction pipe can also be increased. Of course, the outer pipe body 21 and the inner pipe body 22 can be coaxially arranged, which can be set according to requirements and will not be specifically limited here.

[0030] In this embodiment, a strip-shaped opening penetrating the outer pipe body 21 is formed along the axial direction of the outer pipe body 21. A locking plate 33 is accommodated in the active cavity, and the locking groove 331 is formed on the locking plate 33. By opening the strip-shaped opening, the locking plate 33 provided with the locking groove 331 is fixed in the active cavity, and the outer wall of the outer pipe body 21 remains nearly cylindrical, which is convenient for the outer pipe body 21 to be closely connected with the first pipe body 1 and can slide relative to each other.

[0031] In this embodiment, the locking member includes a housing 31 fixed to the end of the first pipe body 1, a locking rod 34 disposed along the radial direction of the first pipe body 1, and an elastic member (not shown) connected between the housing 31 and the locking rod 34. The elastic member is in a compressed state to press the locking rod 34 against the housing 31 in a direction away from the first pipe body 1, and the locking portion 341 of the locking rod 34 cooperates with the positioning groove to lock the relative positions of the first pipe body 1 and the second pipe body 2. By pressing the elastic member with a finger to move it in the direction of the axis of the first pipe body 1, the locking portion 341 of the locking rod 34 is separated from the locking groove 331, facilitating the adjustment of the relative positions of the first pipe body 1 and the second pipe body 2.

[0032] In this embodiment, the elastic member is a spring, and the spring is sleeved on the locking rod 34. By compressing the spring, the locking portion 341 of the locking rod 34 cooperates with the locking groove 331 to lock the relative positions of the first pipe body 1 and the second pipe body 2, and at the same time, it can be quickly unlocked under an external force, which is convenient for operation.

[0033] In this embodiment, the locking member further includes a pressing cap 32. The pressing cap 32 is disposed inside the housing 31 and only partially extends out of the housing 31. The locking rod 34 is connected to the pressing cap 32, and the spring is connected between the pressing cap 32 and the housing 31. An installation groove is provided inside the pressing cap 32 to facilitate the fixation of the spring. In addition, the pressing cap 32 is provided to facilitate finger pressing.

[0034] In this embodiment, the end of the locking rod 34 is the locking portion 341, and an active portion 342 is formed concave inward in the radial direction near the locking portion 341 of the locking rod 34. The locking groove 331 is a circular groove, and the active groove 332 is a long strip groove with a width smaller than that of the circular groove. Therefore, by disposing the active portion 342 close to the locking portion 341, the pressing force that needs to be applied can be reduced, facilitating the unlocking of the first pipe body 1 and the second pipe body 2.

[0035] In this embodiment, a clamping member is provided at one end of the second pipe body 2 inside the first pipe body 1, and the clamping member is in abutting connection with the housing 31. The inner wall of the clamping member is fixedly connected to the second pipe body 2, the outer wall of the clamping member is in abutting connection with the inner wall of the first pipe body 1, and one end of the clamping member is in abutting connection with the end of the housing 31. The clamping member can prevent the second pipe body 2 from detaching from the first pipe body 1, and at the same time, it can also increase the sealing performance of the dust suction channel formed between the first pipe body 1 and the second pipe body 2.

[0036] In this application, by providing a locking assembly between the first pipe body and the second pipe body, the relative positions of the first pipe body and the second pipe body are adjusted by the cooperation of the locking member and the positioning groove to adjust the overall length of the dust suction pipe, so that the dust suction pipe can move freely in a narrow space for cleaning work. At the same time, when storing, the length of the dust suction pipe can be shortened, which is convenient for storage and saves space.

[0037] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0038] The above-described embodiments only express several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
