[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model. Example

[0023] Reference Figure 1-7 The illustration shows a flexible shaft release mechanism for a pipe cleaner proposed in this embodiment. Through the sliding clutch cooperation of release and sliding release, it can realize quick power transmission and cut-off between the flexible shaft and the output shaft and avoid the output shaft from locking up. At the same time, it can realize quick disassembly and maintenance.

[0024] Specifically, the flexible shaft release mechanism of the pipe cleaner includes an output shaft 100, a release 200, a sliding release 300, a sliding member 400, and a flexible shaft connector 500. The output shaft 100 is connected to a motor and outputs rotational power. The flexible shaft connector 500 is used to install and connect the flexible shaft. The sliding member 400 is fixedly disposed at one end of the flexible shaft connector 500 located at the sliding release 300. The sliding member 400 is disposed between the output shaft 100 and the flexible shaft connector 500 for connection between the two. At the same time, the release 200 is fixedly connected to the output shaft 100, and the sliding member 400 is slidably disposed on the sliding member 400, which enables the sliding release 300 to slide left and right on the sliding member 400. The sliding release 300 and the release 200 have a sliding clutch engagement, and the two have an engaged state and a disengaged state. In the engaged state, they can rotate synchronously, and in the disengaged state, there is no transmission relationship.

[0025] In layman's terms, when the sliding release 300 slides against the release 200, the two are in an engaged state. After the output shaft 100 and the release 200 are fixed, power is transmitted to the release 200. Meanwhile, the sliding release 300 is in an engaged state, and the release 200 transmits power to the sliding release 300. Since the sliding release 300 and the sliding member 400 can only move left and right, after being limited, the two also rotate synchronously. The sliding member 400 is also fixed with the flexible shaft connector 500, which drives the flexible shaft connector 500 to rotate synchronously. In other words, the power is ultimately transmitted to the flexible shaft, causing it to rotate and thus perform the pipe unblocking operation.

[0026] Conversely, if the operation does not require the rotation of the flexible shaft, the sliding release 300 is moved away from the release 200 until the sliding release 300 and the release 200 are separated and in a disengaged state. In this disengaged state, there is no transmission relationship, which also prevents the output shaft 100 from locking when the flexible shaft is locked, thus improving the safe use of the equipment.

[0027] Furthermore, to achieve the sliding of the slip release 300 on the sliding member 400 and the resistance contact, this embodiment provides a preferred solution. The flexible shaft release mechanism also includes a spring 600 and a stop block 700. Specifically, the stop block 700 is fixedly disposed on the flexible shaft connector 500, and the spring 600 is sleeved on the flexible shaft connector 500, with its two ends respectively contacting the stop block 700 and the slip release 300. That is, when the slip release 300 slides left and right on the sliding member 400, the spring 600 provides the resistance to the sliding. When the slip release 300 contacts the release 200, the spring 600 is in a compressed state, so that the contact between the slip release 300 and the release 200 is more tight.

[0028] This embodiment also proposes a connection method between the output shaft 100 and the flexible shaft connector 500. The sliding member 400 includes a rack 401, a fixed end 402, and a positioning end 403.

[0029] Specifically, the sliding release 300 has a toothed groove 301 that corresponds to and engages with the rack 401, the flexible shaft connector 500 has a mounting hole 501 that corresponds to and is installed on the fixed end 402, and the output shaft 100 has a positioning hole 101 that corresponds to and rotates on the positioning end 403. It should be noted that the toothed groove 301 that corresponds to and engages with the rack 401 allows for left and right movement, and the sliding release 300 and the sliding member 400 rotate synchronously. The positioning hole 101 and the mounting hole 501 ensure that the release 200... When docking with the sliding release 300, they are precisely aligned on the same plane for positioning. The fixed end 402 is fixedly connected to the mounting hole 501 with screws, and the two cannot rotate relative to each other. The positioning end 403 and the positioning hole 101 only serve a positioning function, and relative rotation can occur between the positioning end 403 and the positioning hole 101. This method ensures that there is no transmission relationship between the output shaft 100 and the sliding member 400 and the flexible shaft connector 500, and there is only a unique transmission relationship between the output shaft 100 and the sliding release 300.

[0030] Meanwhile, to ensure that the release 200 does not have a transmission relationship with other parts, when the positioning end 403 is embedded in the positioning hole 101 to the lowest point, the release 200 does not contact the rack 401. The setting of the installation length of the positioning end 403 also plays a certain limiting role, which makes it impossible for the release 200 to contact the rack 401, and in this state it just happens to be in contact with the sliding release 300.

[0031] Reference Figure 4-5The diagram illustrates the engagement and disengagement of the trip release 200 and the sliding trip release 300. In this embodiment, the opposite sides of the trip release 200 and the sliding trip release 300 are provided with a first protrusion 201 and a first groove 202, which are evenly distributed at intervals. The opposite sides of the sliding trip release 300 and the trip release 200 are provided with a second protrusion 302 and a second groove 303, which are also evenly distributed at intervals.

[0032] Furthermore, both the first protrusion 201 and the second protrusion 302 are provided with guide surfaces 800. Through the sliding of the sliding release 300, the first protrusion 201 can be embedded and limited within the second groove 303, and the second protrusion 302 can be embedded and limited within the first groove 202. In this embodiment, the first protrusion 201 and the first groove 202, as well as the second protrusion 302 and the second groove 303, are arranged in three circumferentially spaced intervals. However, those skilled in the art will understand that the relative numbers can be set according to actual needs. The release 200 and the sliding release 300 are relatively symmetrical structures. By rotating at a certain angle and guided by the guide surfaces 800, the first protrusion 201 can disengage from the second groove 303, and the second protrusion 302 can disengage from the first groove 202, achieving a separation state.

[0033] Conversely, when rotated by a certain angle, under the elastic force of the guide surface 800 and the spring 600, the first protrusion 201 is embedded in the second groove 303 for a limit, and the second protrusion 302 is embedded in the first groove 202 for a limit, thus achieving the engagement state.

[0034] Reference Figure 6-7 As illustrated, in order to limit the sliding range of the sliding release 300, the flexible shaft connector 500 in this embodiment also includes a mounting part 502, with mounting holes 501 and stops 700 respectively disposed at both ends of the mounting part 502.

[0035] Specifically, the fixed end 402 is embedded in the mounting hole 501, and the surface of the mounting part 502 is higher than the surface of the sliding member 400. The two ends of the sliding trajectory of the sliding trip 300 are respectively limited by the mounting part 502 and the trip 200. That is, when the sliding trip 300 moves to the farthest end in the direction of the trip 200, it abuts against the trip 200 under the elastic force of the spring 600. When the sliding trip 300 moves to the farthest end in the opposite direction of the trip 200, the spring 600 is compressed and then abutted by the mounting part 502 which is set above the surface, and it cannot continue to move, thus limiting the sliding range of the sliding trip 300.

[0036] Furthermore, the flexible shaft release mechanism of the pipe cleaner proposed in this embodiment also includes a shaft bracket 900 respectively disposed on the output shaft 100 and the flexible shaft connector 500, for supporting the rotation of the output shaft 100 and the flexible shaft connector 500. It should be noted that the flexible shaft release mechanism of this embodiment includes a bushing disposed thereon, the bushing being hollow inside, for accommodating the output shaft 100, release 200, sliding release 300, sliding member 400 and flexible shaft connector 500, while the shaft bracket 900 is disposed at both ends of the bushing, and the two can rotate, that is, the output shaft 100, release 200, sliding release 300, sliding member 400 and flexible shaft connector 500 are all disposed inside the bushing and can rotate.

[0037] The usage process of this embodiment is as follows: When the flexible shaft needs to be rotated for pipe dredging operations, first install the flexible shaft on the flexible shaft connector 500, referring to... Figure 6-7 The diagram illustrates the installation of the flexible shaft, although it is not explicitly shown. The flexible shaft is located on the left side of the flexible shaft connector 500. Next, the sliding release 300 is moved to abut against the release 200. Under the elastic force of the guide surface 800 and the spring 600, the first protrusion 201 is engaged within the second groove 303, and the second protrusion 302 is engaged within the first groove 202, achieving the engagement state. At this time, the drive output shaft 100 outputs power to rotate and transmits it to the flexible shaft connector 500 for synchronous rotation, thus initiating the flexible shaft's rotation operation.

[0038] When the flexible shaft rotation is not required for pipe dredging operations, the sliding release 300 is moved away from the release 200 until the two separate, achieving the disengaged state. It is easy to understand that the disengaged state in this embodiment should include using screws or clips to fix the position of the sliding release 300 to maintain the disengaged state. This will not be described in detail. That is, under the action of the guide surface 800, the first protrusion 201 is disengaged from the second groove 303, and the second protrusion 302 is disengaged from the first groove 202, achieving the disengaged state.

[0039] In this embodiment, due to the guide surface 800 and the spring 600, if the flexible shaft locks during operation and the output shaft 100 fails to disconnect the power output in time, the sliding release 300 will also be locked due to the locked flexible shaft, while the release 200 will be rotating. Therefore, under the action of the guide surface 800, the first protrusion 201 in the second groove 303 and the second protrusion 302 in the first groove 202 both have a tendency to disengage. The spring 600 can release this tendency by compression, thus achieving the disengagement of the first protrusion 201 in the second groove 303 and the disengagement of the second protrusion 302 in the first groove 202, thereby preventing the output shaft 100 from locking and improving safety.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description and ideas. It is neither necessary nor possible to exhaustively describe all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the technical solution of this utility model should be covered within the scope of protection of the claims of this utility model.
