Description

Technical Field

[0001] The invention relates to the field of mops, in particular to a rod. Background Art

[0002] Mop is one of the most commonly used cleaning tools in people's daily life. With the improvement of people's living standards, there are more and more types of mops to meet the actual needs of different customers. In a more traditional mop, a handheld mop rod is fixedly connected above the mop head, so that cleaning can be achieved without bending over significantly during cleaning, and the cleaning distance and cleaning range can be increased. However, the fixed connection between the mop head and the mop rod is relatively limited, so the prior art further sets the connection between the mop head and the mop rod as a rotating connection, such as the application number: 202121920594.X, entitled: A mop head with a double structure fixing a rag, so as to achieve multi-angle cleaning and increase the adaptability of the mop, but the setting of the rotating connection is not stable, and it is inconvenient to grasp the direction of the mop when using it, so some locking steering structures have appeared in the prior art, which lock the rotating part through an external fixing part or an internal locking mechanism, but the current locking device cannot stably maintain the switched state after switching the locked state or the unlocked state, so that the instability causes trouble during use, so it is very necessary to re-propose a rod. Summary of the invention

[0077] In the description of the present invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0078] See also Figure 1-12 , embodiments of the present invention:

[0079] Embodiment 1:

[0080] like Figure 1 , 2 , 5 and 7: A rod member, comprising a rod body 1 and a connecting member 2, wherein the rod body 1 and the connecting member 2 are hinged, and a locking structure is provided on the rod body 1, wherein the locking structure can form a locked state and an unlocked state with the connecting member 2, and the locking structure comprises:

[0081] The stopper 3 is arranged in the cavity 24 inside the rod body 1, can slide along the rod body 1, one end of which extends in the direction close to the connecting member 2 and is provided with a first clamping portion 9, which is used to cooperate with the second clamping portion 8 provided on the connecting member 2 to complete the locking state and unlocking state between the rod body 1 and the connecting member 2, and the other end of which is provided with a first inclined surface 5;

[0082] A reset member 4, which is arranged between the stop member 3 and the rod body 1, and is used to make the stop member 3 have a tendency to slide in a direction away from the connecting member 2;

[0083] A switch member 6, wherein the switch member 6 is slidably connected to the rod body 1, and a second inclined surface 7 is provided on the switch member 6 to abut against the first inclined surface 5;

[0084] The rod body 1 or the stop member 3 is provided with a first limiting structure, and the switch member 6 is provided with a second limiting structure;

[0085] When the switch member 6 slides from the unlocked position to the locked position, the second inclined surface 7 abuts against the first inclined surface 5 to make the stop member 3 slide toward the connecting member 2, thereby completing the engagement of the first engaging portion 9 and the second engaging portion 8, and the engagement of the first limiting structure and the second limiting structure, thereby achieving locking between the rod body 1 and the connecting member 2;

[0086] During the process of the switch member 6 sliding from the locked position to the unlocked position, the first limit structure and the second limit structure are separated, and the stop member 3 slides in the direction away from the connecting member 2 under the abutment of the reset member 4, so that the first clamping portion 9 and the second clamping portion 8 are separated, thereby realizing the unlocking between the rod body 1 and the connecting member 2.

[0087] Through the arrangement and cooperation of the first limiting structure and the second limiting structure, this embodiment can ensure that after pushing the switch member 6 to slide, the rod body 1 and the connecting member 2 can be in a relatively stable connection state after rotational locking and rotational unlocking, reducing the tendency of the switched state to switch to another state, so as to achieve the state expected by the user after operating the switch member 6, whether in use or idle.

[0088] like Figure 3 , 4 , 6 and 7: the first limiting structure is an arc-shaped groove, and the second limiting structure is an arc-shaped protrusion;

[0089] At least two connection holes 10 are formed on the outer wall of the rod body 1, the connection holes 10 are connected to the cavity 24, and the switch member 6 can slide in the connection holes 10;

[0090] Both ends of the first inclined surface 5 are connected to first abutting surfaces 11, and there is a height difference between the two first abutting surfaces 11;

[0091] Both ends of the second inclined surface 7 are connected with second abutment surfaces 12, and there is a height difference between the two second abutment surfaces 12 in the horizontal direction;

[0092] The first abutting surface 11 at a higher position slides against the second abutting surface 12 at a higher position, and the first abutting surface 11 at a lower position slides against the second abutting surface 12 at a lower position;

[0093] The first limiting structure includes a first limiting member 13, which is arranged on the first abutting surface 11. The second limiting structure includes a second limiting member 14, which is arranged on the second abutting surface 12. The first limiting member 13 and the second limiting member 14 are both set in two numbers. The first limiting member 13 is located on two first abutting surfaces 11 at different heights, and the second limiting member 14 is located on two second abutting surfaces 12 at different heights, that is, a limiting member is arranged on each abutting surface.

[0094] In this embodiment, the first limiting structure and the second limiting structure are both configured in an arc shape in order to make the connection and separation processes of the two smoother during switching and improve the convenience of operation.

[0095] like Figure 3 ,4 , 6 and 7: both ends of the inclined surface are connected to the first abutting surface 11, and there is a height difference between the two first abutting surfaces 11;

[0096] Both ends of the second inclined surface 7 are connected with second abutment surfaces 12, and there is a height difference between the two second abutment surfaces 12 in the horizontal direction;

[0097] The first abutting surface 11 at a higher position slides against the second abutting surface 12 at a higher position, and the first abutting surface 11 at a lower position slides against the second abutting surface 12 at a lower position.

[0098] In this embodiment, the height difference between the abutting surfaces is used to convert the height difference into a different height of the bottom of the stop member 3 , so as to complete the engagement and separation between the first engaging portion 9 and the second engaging portion 8 .

[0099] like Figure 6 As shown: a groove 17 is provided on the side wall of the switch member 6, and the groove 17 is located outside the connecting hole 10;

[0100] The switch member 6 slides in the connecting hole 10 by pressing the switch member 6 and pulling the groove 17, thereby switching between the locked state and the unlocked state of the position between the rod body 1 and the connecting member 2.

[0101] In this embodiment, the pull groove 17 is provided in addition to the unlocking end 15 and the locking end 16 in order to provide more different ways of moving the switch member 6 to improve the adaptability of the present application.

[0102] like Figure 1 , 2 , 5 and 8: the first stopper 13 is disposed on the two first abutting surfaces 11 of different heights, and the second stopper 14 is disposed on the two second abutting surfaces 12 of different heights;

[0103] The second stopper 14 at the lower position is connected to the first stopper 13 at the higher position, completing the connection between the first clamping portion 9 and the second clamping portion 8, and achieving a locked state;

[0104] The second limiting member 14 at the lower position is separated from the first limiting member 13 at the higher position, so that the first clamping portion 9 and the second clamping portion 8 are separated and the unlocking state is achieved;

[0105] The second limiting member 14 at a higher position is connected to the first limiting member 13 at a higher position, and the second limiting member 14 at a lower position is connected to the first limiting member 13 at a lower position, so as to maintain the stability of the unlocking state.

[0106] like Figure 3, 4 As shown in FIG. 6 , the switch member 6 has an unlocking end 15 and a locking end 16, and two connecting holes 10 are symmetrically arranged on the rod body 1, and the distance between the end surface of the unlocking end 15 and the end surface of the locking end 16 is greater than the distance between the two connecting holes 10 on the side wall of the rod body 1;

[0107] Press the unlocking end 15, the end surface of the locking end 16 protrudes from the outer wall of the rod body 1, and the position between the rod body 1 and the connecting member 2 is in a unlocking state;

[0108] By pressing the locking end 16 , the end surface of the unlocking end 15 protrudes from the outer wall of the rod body 1 , and the position between the rod body 1 and the connecting member 2 is in a locked state.

[0109] In this embodiment, by setting the unlocking end 15 and the locking end 16, the state switching can be completed by pressing the unlocking end 15 or the locking end 16 during use, and the distance from the end face of the unlocking end 15 to the end face of the locking end 16 is greater than the distance between the two connecting holes 10 on the side wall of the rod body 1. In this embodiment, the specific setting is that after pressing any one end to complete the switching, the end pressed during the switching process will be located in the connecting hole 10 and flush with the end face of the connecting hole 10, while the other end will extend out of the connecting hole 10, that is, it can be understood that the distance between the unlocking end 15 and the locking end 16 in the above-mentioned process is equivalent to the distance of the switch member 6, and the part of this distance that is greater than the distance between the two connecting holes 10 is the same as the moving distance of the switch member 6 each time the state is switched, so that in the next switching process, the protruding end can be better pressed to complete the state switching, and the other end is in the connecting hole 10, and the stability of the overall structure will not be affected by accidental touch.

[0110] like Figure 6 and 8 As shown: a first limiting portion 18 is provided in the axial direction of the inner side wall of the connecting hole 10;

[0111] A second limiting portion 19 is axially arranged on the outer side wall of the switch member 6;

[0112] The first limiting portion 18 and the second limiting portion 19 slide against each other to complete the sliding guidance and rotation limiting of the switch member 6 in the connecting hole 10 .

[0114] The unlocking end 15 and the locking end 16 are connected via a connecting shaft 21, the second abutting portion is disposed on the connecting shaft 21, and the second limiting portion 19 is disposed on the unlocking end 15;

[0115] The connecting shaft 21 slides against the inner wall of the third limiting portion 20 , and the inner end surfaces of the unlocking end 15 and the locking end 16 can abut against the third limiting portion 20 , completing the sliding abutment of the switch member 6 in the connecting hole 10 .

[0116] In this embodiment, in order to prevent bumps, the unlocking end 15 and the locking end 16 on the switch member 6 are both set to be cylinders. However, if the switch member 6 has a cylindrical contour except for the second inclined surface 7 and the second abutment surface 12, the switch member 6 will rotate and deviate during the movement. In order to prevent the switch member 6 from excessive movement and rotation during movement, this embodiment limits the switch member 6 by setting a first limit portion 18, a second limit portion 19 and a third limit portion 20, so that the application can maintain sufficient stability during the switching process.
