Description

Technical Field

[0001] The utility model particularly relates to a rod connection structure of a detachable pull rod. Background Art

[0002] At present, there are many types of toilet brushes on the market. For example, a toilet brush includes a grip and a cleaning head. During the assembly and maintenance of the grip, the detachable pull rod connecting the transmission handle is usually difficult to disassemble or has many parts, resulting in complicated assembly.

[0003] For example, a toilet brush disclosed in Chinese patent announcement number CN212816060U discloses that the gripping rod includes an upper cover and a lower cover, and the upper and lower covers are connected by a detachable structure; a slide groove is provided between the upper and lower covers, and the operating rod is installed in the slide groove, and the operating rod can move in the slide groove without being separated. There are many detachable structures, such as the upper and lower covers are connected by a screw structure or the upper and lower covers are connected by a buckle structure; the slide groove is provided with a limiter that can prevent the operating rod from being separated.

[0004] In summary, the current toilet brush handle is connected by screws or buckles. The screw connection requires external special tools for disassembly and assembly, which is relatively inconvenient. The buckle structure is prone to damage due to incorrect force during disassembly and assembly or falling from a high altitude, thus affecting subsequent installation. Utility Model Content

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0024] like Figures 1 to 6 As shown, the embodiment of the utility model preferably provides a rod connection structure of a detachable pull rod, including a first connecting rod 1 and a second connecting rod 2 which are plugged into each other, a connecting head 3 is provided at one end of the first connecting rod 1, a first concave cavity 4 is recessed at one end of the second connecting rod 2, a first clamping groove 5 which can be clamped with the connecting head 3 is provided in the first concave cavity 4; wherein, the first clamping groove 5 includes a first limiting cavity 51 and a second limiting cavity 52 which are sequentially connected along the depth direction of the first concave cavity 4, and the width of the second limiting cavity 52 is greater than the width of the first limiting cavity 51; when the connecting head 3 is in a vertical state, it can pass through the first limiting cavity 51 and move into the second limiting cavity 52; when the connecting head 3 is in a horizontal state, its limiting card is placed in the second limiting cavity 52 and cannot pass through the first limiting cavity 51. Specifically, the first connecting rod is manually screwed to switch the connecting head thereon between a horizontal state and a vertical state relative to the second connecting rod. Then, during the installation process of the first connecting rod and the second connecting rod, the vertical state and the horizontal state of the connecting head are respectively switched with the matching state of the first slot to realize the assembly and disassembly connection between the first connecting rod and the second connecting rod.

[0025] Furthermore, the cross section of the first slot 5 is in a "T" shape or an inverted "L" shape, and one end of the connector 3 is in a "T" shape or an inverted "L" shape corresponding to the first slot 5.

[0026] Furthermore, a second card slot 53 is provided through one side of the first connecting rod 1 or the second connecting rod 2, and an elastic card buckle 54 which can cooperate with the second card slot 53 is protruded from one side of the first connecting rod 1 or the second connecting rod 2; when the elastic card buckle 54 is engaged in the second card slot 53, the connector 3 is in a horizontal state and remains in a connected state engaged in the second limiting cavity 52. ​​Specifically, when the second card slot is located on the first connecting rod, the elastic card buckle is correspondingly located on the second connecting rod and engaged with the second card slot on the first connecting rod; conversely, when the second card slot is located on the second connecting rod, the elastic card buckle is correspondingly located on the first connecting rod and engaged with the second card slot of the second connecting rod.

[0027] Then, the second card slot cooperates with the elastic card buckle to realize relative locking and anti-rotation between the first connecting rod and the second connecting rod, thereby ensuring that the connecting head is in a connection state of being horizontally clamped in the second limiting cavity, and realizing the installation, connection and fixation of the first connecting rod and the second connecting rod;

[0028] When the first connecting rod and the second connecting rod need to be disassembled, the user only needs to manually apply force to the elastic buckle to make the elastic buckle elastically deform and disengage from the second slot, so as to restore the relative rotation activity between the first connecting rod and the second connecting rod. At this time, the first connecting rod is screwed to make the connecting head in a vertical state, so that the connecting head can be relatively disengaged and moved axially through the first limiting cavity of the first slot, thereby realizing the relative separation and disassembly of the first connecting rod and the second connecting rod. The structure is simple and the operation is convenient.

[0029] Furthermore, the connector 3 can be elastically deformed and arranged on the first connecting rod 1, the first concave cavity 4 is provided with a first connecting member 11, the first clamping groove 5 is formed on the first connecting member 11, and a guide inclined surface 12 that can contact the connector 3 is arranged on the side wall of one end of the first connecting member 11; when the connector 3 is in a horizontal state, it can move with the first connecting rod 1 and contact the guide inclined surface 12, so that it is elastically deformed and clamped in the second limiting cavity 52. ​​Furthermore, the guide inclined surface can be used to make the connector in a horizontal state and can be directly clamped in the second limiting cavity of the first clamping groove through its elastic deformation, so as to realize the rapid docking installation of the connector and the first clamping groove. Therefore, no matter whether the connector is in a horizontal state or a vertical state relative to the first clamping groove, it can directly dock with the first clamping groove.

[0030] Furthermore, a second cavity 13 is concavely formed at one end of the first connecting rod 1, the connecting head 3 is located in the second cavity 13, one end of the second connecting rod 2 can be plugged into the second cavity 13, a second connecting piece 14 is provided in the second cavity 13, and the connecting head 3 is formed at one end of the second connecting piece 14. The second connecting piece can be integrally formed in the second cavity or can be detachably installed in the second cavity, and it is sufficient that the connecting head can rotate with the first connecting rod.

[0031] Furthermore, the second connecting member 14 is detachably connected to the second cavity 13. When the connector is damaged, the user can directly replace the second connecting member, thus avoiding the need for replacing the entire first connecting rod, and effectively saving costs.

[0032] Furthermore, the first connecting member 11 is detachably connected to the first cavity 4. When the first card slot is damaged, the user can directly replace the first connecting member, avoiding the need for overall replacement of the second connecting rod, effectively saving costs.

[0033] Furthermore, if Figure 1 and Figure 2 As shown, the elastic buckle 54 is connected to the first connecting rod 1 or the second connecting rod 2 by integral molding.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model.
