Description

TECHNICAL FIELD

[0001] The present application relates to the field of mops, in particular to a rod. BACKGROUND

[0002] The mop is one of the most commonly used cleaning tools in people's daily life. With the increasing improvement of people's living standards, the types of mops are also increasing to meet the actual needs of different customers. The relatively traditional mop has a hand-held mop rod fixedly connected above the mop head to realize cleaning without a large amplitude of bending over, increase the cleaning distance and cleaning range, but the fixed connection between the mop head and the mop rod is relatively limited, so the connection between the mop head and the mop rod is further set as a rotating connection in the prior art, such as the mop head with double structure fixed cloth in application No. 202121920594.X, to realize multi-angle cleaning and increase the adaptability of the mop. However, the rotating connection is not stable, and it is not convenient to control the direction of the mop during use, so some steering structures that can be locked appear in the prior art, which lock the rotating part by external fixing parts or internal locking mechanisms. However, the current locking device cannot stably maintain the state after switching the locking state or the unlocking state, which causes trouble during use due to the instability, so it is necessary to re-propose a rod. SUMMARY

[0132] The first abutting surface in the higher position is in sliding abutment with the second abutting surface in the higher position, and the first abutting surface in the lower position is in sliding abutment with the second abutting surface 13 in the lower position.

[0133] In this embodiment, the first abutting surface and the second abutting surface in example 1 are arranged at the same time, and the first limiting structure is arranged in the connecting hole as in example 2.

[0134] Example 4:

[0135] The difference between this embodiment and example 3 is that the number of connecting holes

[0136] Specifically, the outer side wall of the rod body is provided with one connecting hole, which is communicated with the cavity, and the switch piece can slide in the connecting hole.

[0137] A pulling groove is arranged on the side wall of the switch piece, and the pulling groove is located outside the connecting hole.

[0138] The sliding of the switch piece in the connecting hole is completed by pressing the switch piece and pulling the pulling groove, so as to switch between the position locking state and the position unlocking state of the rod body and the connecting piece.

[0139] In this embodiment, the connecting hole is arranged as one, so first, the movement of the switch piece cannot be completed by pressing the unlocking end and the locking end as in example 1. For the arrangement of only one connecting hole in this embodiment, the movement of the switch piece is realized by pressing the switch piece and pulling the pulling groove. The first limiting piece in the first limiting structure is arranged in the connecting hole, and the second limiting piece in the second limiting structure is arranged on the side wall of the switch piece. The arrangement of this embodiment is equivalent to arranging the first limiting structure and the second limiting structure on the switch piece and the corresponding connecting hole at the same end in example 2.

[0140] Example 5:

[0141] The difference between this embodiment and Embodiment 1 is that the settings of the first limiting structure and the second limiting structure are different.

[0142] Specifically: one of the first limiting structure and the second limiting structure is an arc-shaped protrusion, and the other is an arc-shaped groove;

[0143] At least one connecting hole is provided on the outer side wall of the rod, the connecting hole is in communication with the cavity, and the switching element can slide in the connecting hole;

[0144] The first limiting structure is disposed on the side wall of the stop member;

[0145] The switch is provided with a connecting part, one end of which extends from one side of the second inclined surface away from the second inclined surface to the side wall of the stop member, and the second limiting structure is provided on the connecting part.

[0146] In this embodiment, specifically, on the side wall of the stop member, and on both sides of the first inclined surface, there are first limiting members in the first limiting structure, and two first limiting members of different heights are provided on each side, that is, a total of four. The two first limiting members of different heights on the same side are connected by a slot, and the connecting part extends from both sides of the second inclined surface. The second limiting member in the second limiting structure is located inside the two connecting parts and is connected to the first limiting member. When switching, the second limiting member moves between the two limiting members of different heights on the same side to complete the state switching.

[0147] Example 6:

[0148] The difference between this embodiment and embodiment 6 is: the number of second limiting members.

[0149] like Figures 9-10 As shown: Specifically, a first limiting member 13 is provided on both of the two first abutting surfaces of different heights, and a second limiting member 14 is provided on the second abutting surface at the lower position;

[0150] The second limiting member 14 is connected to the first limiting member 13 located at a higher position, completing the connection between the first locking part 9 and the second locking part 8, and realizing the locking state;

[0151] The second limiting member 14 separates from the first limiting member 13 located at a higher position, completing the separation of the first locking part 9 and the second locking part 8, and realizing the unlocked state;

[0152] The second limiting member 14 is connected to the first limiting member 13 at a lower position to maintain the stability of the unlocked state.

[0153] In the embodiment, the number of the first limit members 13 and the second limit members 14 is two to one, so that by moving the switch member 6, the second limit members 14 on the second abutting surface 12 are respectively connected with the first limit members 13 on the first abutting surface 11 of different heights, to complete the stability after the state switching.

[0154] Embodiment 7

[0155] The difference between the embodiment and the embodiment 1 is that the number of the first limit members

[0156] As shown in the drawings, specifically, the first abutting surface 11 at the higher position is provided with the first limit member 13, and the two second abutting surfaces 12 at different heights are both provided with the second limit member 14. Figures 11-12

[0157] The first limit member 13 is connected with the second limit member 14 at the lower position, to complete the connection of the first clamping part 9 and the second clamping part 8, and realize the locking state.

[0158] The first limit member 13 is separated from the second limit member 14 at the lower position, to complete the separation of the first clamping part 9 and the second clamping part 8, and realize the unlocking state.

[0159] The first limit member 13 is connected with the second limit member 14 at the higher position, to keep the stability of the unlocking state.

[0161] Embodiment 8

[0162] The difference between the embodiment and the embodiment 1 is the moving mode of the switch member

[0163] Specifically, the switch member is provided with a rotating member.

[0164] The rod body is provided with a sliding groove.

[0165] The end of the rotating member extends out of the rod body from the sliding groove.

[0166] By operating the rotating member to complete the sliding of the switch member in the connecting hole, the switching between the position locking state and the position unlocking state between the rod body and the connecting member is realized.

[0167] In the embodiment, the moving of the switch member is completed by setting the moving rotating member, which is different from the pressing of the unlocking end and the locking end in the embodiment 1, and is also different from the pulling of the pulling groove to realize the moving of the switch member.​
