Description

TECHNICAL FIELD

[0001] The utility model relates to a button, especially a connecting rod locking button and locking device. BACKGROUND

[0002] In order to realize the lengthening of the rod during use, two rods are usually spliced together, and a locking device is further needed to lock the two rods together after splicing to prevent the two rods from separating. For example, CN215457752U discloses a mop with detachable mop rod, which comprises a mop body, a mop rod and a quick connector. The mop body and the mop rod are connected through the quick connector. The quick connector comprises an elastic member and a pressing member. The positioning protrusions on the inner wall of the elastic member are in positioning cooperation with the mop body and the mop rod. Specifically, the elastic member is wrapped around the end of the mop body, the pressing member is eccentrically arranged at the opening of the elastic member, the bottom end of the mop rod is placed in the mop body, and the mop rod and the mop body are respectively provided with positioning holes. After assembly, the positioning protrusions are placed in the positioning holes to fix the mop rod and the mop body. When the pressing member is pressed, the elastic member moves after deformation, the positioning protrusions are separated from the mop body and the mop rod, and the mop rod can be detached from the mop body. Although the mop realizes the splicing of two pipes, the elastic member needs to cooperate with the pressing member to act, the two need to be assembled together, and a connecting sleeve is further needed for positioning, resulting in more parts, complex part structure, high cost and complex assembly.

[0029] The utility model will be further described in connection with the drawings.

[0030] As Figures 1 to 5 shown, a connecting rod locking button comprises a button body, the button body comprises a button plate 11, a locking column 13 arranged at one end of the button plate 11, an elastic rod 12 arranged at one side of the locking column 13 and forming an elastic angle A with the button plate 11 and a rotating part 14 symmetrically arranged at both sides of the button plate 11.

[0031] As Figures 6 to 13 shown, the button body is used in cooperation with a locking sleeve 2 or can be directly rotated and installed on the sleeve 4. The elastic rod 12 improves the elastic force, and the elastic rod 12 keeps the locking column 13 in the inserted state. When the button plate 11 is pressed, the button plate 11 rotates around the axis of the rotating part 14 when the force received by the button plate 11 is greater than the elastic force provided by the elastic rod 12, and the end of the button plate 11 provided with the locking column 13 rotates upward, thereby making the locking column 13 separate from the first positioning hole 42 and the second positioning hole 32 on the sleeve 4 and the connector 3, and realizing the disassembly of the sleeve 4 and the connector 3. When the connector 3 and the sleeve 4 are spliced, the locking column 13 is first lifted into the first positioning hole 42 by pressing the button plate 11, then the reduced-diameter pipe 31 of the connector 3 is inserted into the sleeve 4, then the button plate 11 is released, and then the connector 3 is rotated. At this time, the button plate 11 makes the locking column 13 elastically press on the reduced-diameter pipe 31 under the action of the elastic rod 12, and when the first positioning hole 42 is aligned with the second positioning hole 32, the locking column 13 is inserted into the second positioning hole 32 under the action of the elastic rod 12, thereby realizing the locking of the sleeve 4 and the connector 3 and preventing the separation of the sleeve 4 and the connector 3. The button body has a simple structure, can realize both locking and unlocking, greatly reduces the number of parts, reduces the cost, and is simple and convenient to assemble and use.

[0032] The button plate 11 is provided with an elastic pressing groove 16 arranged opposite to the elastic rod 12, the elastic pressing groove 16 is used to accommodate the elastic rod 12 after the button plate 11 is pressed, thereby reducing the thickness of the button plate 11, making the protruding height of the connecting rod locking button smaller, and making the overall structure compact. Meanwhile, the elastic pressing groove 16 makes the periphery of the button plate 11 form a reinforcing edge, thereby ensuring the strength of the button plate 11 and preventing the button plate 11 from being deformed when pressed.

[0033] To further reduce the length of the button plate 11, one end of the button plate 11 is provided with a relief groove 17 that communicates with the elastic pressure groove 16 and is disposed opposite to the end of the elastic rod 12. When the button plate 11 is pressed onto the elastic rod 12, the end of the elastic rod 12 is located in the relief groove 17, so there is no need to increase the length of the button plate 11.

[0034] In order to make the end of the elastic rod 12 move more smoothly when it is compressed, the elastic rod 12 is provided with a sliding arc surface 121, which can effectively reduce friction.

[0035] When the rotating part 14 adopts a rotating shaft, in order to facilitate the installation of the rotating part 14 on the locking sleeve 2, the rotating part 14 is provided with an insertion inclined surface 141. The insertion inclined surface 141 can deform the rotating part 14 into the inside of the button body, which facilitates assembly.

[0036] When the rotating part 14 adopts a rotating shaft, in order to further facilitate the insertion of the rotating part 14 and avoid damage to the rotating part 14 during assembly, elastic grooves 15 are provided on both sides of the rotating part 14. The elastic grooves 15 can increase the elasticity of the rotating part 14 and prevent tearing between the rotating part 14 and the button plate 11 during installation.

[0037] The rotating part can also be a rotating groove, which can be set as needed.

[0038] The end of the locking pin 13 is provided with an insertion arc surface 132, which allows the locking pin 13 to be easily inserted into the locking hole 22, reducing resistance.

[0039] The end of the elastic rod 12 can be located on one side of the locking post 13, or at the end of the button plate 11 away from the locking post 13, that is, the locking post 13 and the elastic rod 12 are located at the two ends of the button plate 11 respectively.

[0040] like Figures 6 to 13 As shown, a linkage locking device includes a linkage locking button 1 and a locking sleeve 2. The locking sleeve 2 is provided with a locking groove 21, and rotating holes 23 are symmetrically provided on both sides of the locking groove 21. The bottom of the locking groove 21 is provided with a locking hole 22. The rotating part 14 is rotatably inserted into the rotating hole 23, the elastic rod 12 is movably pressed against the locking sleeve 2, and the locking pin 13 is movably inserted into the locking hole 22.

[0041] To facilitate the movement of the locking pin 13, the locking hole 22 is an oblong hole. The oblong locking hole 22 can facilitate the movement of the locking pin 13, avoid interference between the locking pin 13 and the locking hole 22, and at the same time, it does not require reducing the diameter of the locking pin 13, thus ensuring the strength of the locking pin 13.

[0042] The locking sleeve 2 facilitates the installation of the connecting rod locking button 1, and can improve the connecting strength of the sleeve 4 and the insertion tube 3. The above functions can be realized only by the locking sleeve 2 and the button body, greatly simplifying the structure, reducing the number of parts, reducing the cost, and being simple in assembly and operation.

These descriptions are only for explaining the principles of the present application, and cannot be interpreted in any way as a limitation on the protection scope of the present application. Based on the explanations herein, other specific embodiments of the present application can be conceived by those skilled in the art without creative labor, and these embodiments will fall within the protection scope of the claims of the present application.
