Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner floor brushes, in particular to a triangular block upright positioning structure for a floor brush. Background Art

[0002] A floor brush is required during the process of a vacuum cleaner sucking dust on the ground. The floor brush increases the operation width of the vacuum cleaner, and the dust is preliminarily collected by the floor brush and then enters the vacuum cleaner through a hose. The floor brush can rotate freely through a swivel joint compared with the vacuum cleaner body. For example, a floor brush capable of multi-angle adjustment disclosed in Chinese Patent CN211381096U belongs to the field of vacuum cleaner equipment. The floor brush capable of multi-angle adjustment includes an upper floor brush cover, a lower floor brush cover, a swivel joint, and a guiding pipe fitting. Clamping members are correspondingly arranged on the upper floor brush cover and the lower floor brush cover of the floor brush capable of multi-angle adjustment. The swivel joint is clamped in the clamping members of the upper floor brush cover and the lower floor brush cover. Under the guiding action of the guiding convex ring and the clamping groove, the swivel joint can rotate 360 degrees in the clamping members. The guiding pipe fitting is arranged on the protruding rotating shaft, and the guiding pipe fitting can rotate around the protruding rotating shaft, and the rotation angle is greater than 90 degrees. Under the combined action of the swivel joint and the guiding pipe fitting, multi-angle rotation of the floor brush can be realized. Four rollers are arranged on the lower floor brush cover, and the presence of the rollers makes it convenient for the floor brush to move itself.

[0003] The freely rotatable floor brush facilitates floor cleaning. However, when the vacuum cleaner is stored, the floor brush is provided with rollers and can rotate flexibly, resulting in easy relative position change between the floor brush and the vacuum cleaner body, leading to changes in the center of gravity and position offset of the vacuum cleaner, and further resulting in collision damage. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a triangular block upright positioning structure for a floor brush to solve the problem of inconvenient storage caused by the existing freely rotatable installation structure of the floor brush of the vacuum cleaner.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A triangular block upright positioning structure for a floor brush, comprising:

[0006] A floor brush body, on which a joint installation groove is provided;

[0007] A swivel joint, which is rotatably installed in the joint installation groove. A rotating shaft is provided on the swivel joint, and a first block and a second block are provided on the rotating shaft. The first block is triangular. A step surface corresponding to the first block is provided on the floor brush body. A first limiting convex block corresponding to the second block is provided on the side wall of the joint installation groove, and the cross-section of the first limiting convex block is triangular;

[0008] A conduit, which is rotatably installed on the swivel joint.

[0009] As a further description of the above technical solution:

[0010] A second limiting protrusion is provided at one end of the stepped surface, and a third clamping block corresponding to the second limiting protrusion in position is provided on the rotating shaft.

[0011] As a further description of the above technical solution:

[0012] The cross-section of the second clamping block is triangular.

[0013] As a further description of the above technical solution:

[0014] The length of the second clamping block is greater than the length of the first limiting protrusion.

[0015] As a further description of the above technical solution:

[0016] A ring groove is also provided on the rotating shaft.

[0017] As a further description of the above technical solution:

[0018] Symmetrically arranged rotating shafts are provided on both sides of the rotary joint.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0020] 1. In the present utility model, when the floor brush body is in use, under normal conditions, the rotary joint rotates freely around the rotating shaft, and the stroke of the first clamping block is the area between the first limiting protrusion and the stepped surface. When the floor brush body needs to be stored, the conduit and the connected vacuum cleaner body rotate counterclockwise to the vertical state. At this time, the second clamping block of the rotary joint is engaged with the first limiting protrusion, the second clamping block contacts the first limiting protrusion, and the first clamping block abuts against the stepped surface, realizing the position locking of the conduit and the connected vacuum cleaner body, facilitating the storage of the vacuum cleaner and avoiding collision damage caused by the unstable center of gravity of the vacuum cleaner.

[0021] 2. In the present utility model, the first clamping block is triangular. On the basis of ensuring the contact area with the stepped surface and ensuring the limiting effect, the width of the end is reduced to avoid friction and collision between the rotary joint and the floor brush body during the rotation process.

[0022] 3. In the present utility model, a second limiting protrusion is provided at one end of the stepped surface, and a third clamping block corresponding to the second limiting protrusion in position is provided on the rotating shaft. During the use of the vacuum cleaner, in cooperation with the first clamping block and the second clamping block, the rotation range of the rotary joint is further restricted, improving the safety during the use of the vacuum cleaner.

[0032] Example 1

[0033] See also Figures 1-5 The utility model provides a technical solution: a triangular card block upright positioning structure of a floor brush, comprising:

[0034] A floor brush body 1, on which a joint mounting groove is provided;

[0035] The rotary joint 2 is rotatably installed in the joint installation groove. A rotating shaft 21 is provided on the rotary joint 2. A first clamping block 211 and a second clamping block 212 are provided on the rotating shaft 21. The first clamping block 211 is triangular. A stepped surface 12 corresponding to the first clamping block 211 in position is provided on the floor brush body 1. A first limiting convex block 11 corresponding to the second clamping block 212 in position is provided on the side wall of the joint installation groove. The cross-section of the first limiting convex block 11 is triangular;

[0036] The conduit 3 is rotatably installed on the rotary joint 2.

[0037] A second limiting convex block 121 is provided at one end of the stepped surface 12. A third clamping block 213 corresponding to the second limiting convex block 121 in position is provided on the rotating shaft 21. When the vacuum cleaner is in use, in cooperation with the first clamping block 211 and the second clamping block 212, the rotation range of the rotary joint 2 is further restricted, improving the safety during the use of the vacuum cleaner.

[0038] The cross-section of the second clamping block 212 is triangular, and the length of the second clamping block 212 is greater than the length of the first limiting convex block 11, effectively ensuring the clamping effect between the second clamping block 212 and the first limiting convex block 11 and ensuring the locking effect.

[0039] A ring groove 214 is further provided on the rotating shaft 21, facilitating the deformation of the end of the rotating shaft 21, thereby facilitating the engagement with the floor brush body 1 and preventing loosening of the connection.

[0040] Symmetrically arranged rotating shafts 21 are provided on both sides of the rotary joint 2. Correspondingly, clamping blocks are provided on both sides, fully ensuring the locking effect between the floor brush and the rotary joint 2.

[0041] Working principle: When the floor brush body 1 is in use, under normal conditions, the rotary joint 2 rotates freely around the rotating shaft 21, and the stroke of the first clamping block 211 is the area between the first limiting convex block 11 and the stepped surface 12. When the floor brush body 1 needs to be stored, the conduit 3 and the connected vacuum cleaner body rotate counterclockwise to the vertical state. At this time, the second clamping block 212 of the rotary joint 2 engages with the first limiting convex block 11. The second clamping block 212 contacts the first limiting convex block 11, and the first clamping block 211 abuts against the stepped surface 12, realizing the position locking of the conduit 3 and the connected vacuum cleaner body, facilitating the storage of the vacuum cleaner and avoiding collision damage caused by the unstable center of gravity of the vacuum cleaner. The first clamping block 211 is triangular. On the basis of ensuring the contact area with the stepped surface 12 and ensuring the limiting effect, the width of the end is reduced to avoid friction and collision between the rotary joint 2 and the floor brush body 1 during the rotation process.

[0042] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
