Technical Field
[0001] The utility model relates to the technical field of car washing brush rollers, and particularly relates to a durable brush roller for car washing with anti - detachment function. Background Art
[0002] A car washing machine is mainly a machine that uses a computer to control brushes and high - pressure water to automatically wash cars. The car washing machine mainly includes a horizontal brush for washing the top of the vehicle, vertical brushes for washing both sides of the vehicle, and bottom brushes for washing the wheels of the vehicle.
[0003] For example, the Chinese patent technical document with the publication number of CN219613290U discloses a fixing structure for the brush pieces of a car washing machine, which includes a brush barrel and a brush. The brush is sequentially inserted into the brush barrel. A brush barrel connection flange is further provided at the top of the brush barrel, and a vertical brush bottom plate is provided at the bottom of the brush barrel. The brush barrel connection flange and the vertical brush bottom plate seal both ends of the brush barrel. A vertical brush drive shaft is also fixedly provided on the brush barrel connection flange, and the vertical brush drive shaft connects the brush barrel with the vertical brush drive mechanism of the car washing machine.
[0004] In the above - mentioned technical solution, the brush is connected to the brush barrel through a brush insertion pin barrel, that is, the brush is slid into the brush insertion pin barrel, and the fixation of the two is completed through the frictional force generated by the contact between the two. However, in the actual use process, it is found that during the long - term rotation of the brush barrel, the brush is continuously affected by the centrifugal force and is likely to detach from the brush barrel, thus affecting the overall durability of the brush barrel. Summary of the Invention
[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a durable brush roller for car washing with anti - detachment function, which can improve the connection stability of the brush strips to improve the overall durability.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A durable brush roller for car washing with anti - detachment function includes a roller body and brush strips. A downward - concave chute is provided on the surface of the roller body. There are multiple chutes and they are evenly distributed in a circumferential direction. A sliding seat is provided at the end of the brush strip. The sliding seat is adapted to the chute and can form a sliding fit with the chute. A locking sleeve is provided on the roller body. There are multiple locking sleeves and they are spaced apart from each other along the axial direction of the roller body. The locking sleeve is used to squeeze both sides of the brush strip to realize the axial limit of the brush strip.
[0007] The utility model is further set as: A protruding blocking protrusion is provided in the chute. The blocking protrusions are symmetrically arranged in the chute. The blocking protrusion is used to radially limit the sliding seat.
[0008] The present utility model is further configured as follows: mounting grooves with notches facing outward are provided on both sides of the locking sleeve. A slidable pressing block is provided in the mounting groove. A pressing spring is provided between the pressing block and the mounting groove. One end of the pressing spring is fixed to the pressing block, and the other end is fixed to the bottom of the mounting groove. There are multiple pressing springs, which are evenly distributed in a circle.
[0009] The present utility model is further configured as follows: a first threaded hole is provided on the roller body. There are multiple first threaded holes, which are spaced apart from each other in the axial direction. A second threaded hole that can be opposite to the first threaded hole is provided on the outer periphery of the locking sleeve. The second threaded hole and the first threaded hole are fixed by a locking member.
[0010] The present utility model is further configured as follows: positioning grooves are provided on the inner wall of the locking sleeve. There are multiple positioning grooves, which are evenly distributed in a circle. A positioning block adapted to the positioning groove is provided on the pressing block. The positioning block is coupled to the positioning groove and can form a sliding fit between the two.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] Due to the setting of the locking sleeve, after the sliding seat of the brush strip is slid into the sliding groove, by sleeving the locking sleeve, the two sides of the brush strip are squeezed by the locking sleeve, so that the brush strip can be axially limited, thereby improving the stability of the brush strip connected to the roller body. Therefore, the technical problem that the brush strip and the roller body are fixed only by the friction generated by the contact between the two in the prior art is effectively solved. Furthermore, it can prevent the brush strip from falling off when the roller rotates, and improve the overall stability of use. Description of the Drawings

[0017] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0019] As Figures 1 to 4 shown, the utility model discloses a durable brush roll for car washing to prevent falling off, which includes a roll body 2 and brush strips 1. A downwardly concave chute 21 is provided on the surface of the roll body 2. There are multiple chutes 21 and they are evenly distributed in a circle. A sliding seat 3 is provided at the end of the brush strip 1. The sliding seat 3 is adapted to the chute 21 and can form a sliding fit with the chute 21. A locking sleeve 4 is provided on the roll body 2. There are multiple locking sleeves 4 and they are spaced from each other along the axial direction of the roll body 2. The locking sleeve 4 is used to squeeze both sides of the brush strip 1 to realize the axial limit of the brush strip 1. After the sliding seat 3 of the brush strip 1 is slid into the chute 21, by sleeving the locking sleeve 4, the locking sleeve 4 squeezes both sides of the brush strip 1. In this way, the axial limit of the brush strip 1 can be realized, thereby improving the stability of the connection between the brush strip 1 and the roll body 2, and further preventing the brush strip 1 from falling off when the roll body 2 rotates, and improving the overall stability of use.
[0020] In this embodiment, a protruding blocking protrusion 5 is further provided on the roll body 2. The blocking protrusions 5 are symmetrically arranged in the chute 21. The blocking protrusion 5 is used for the radial limit of the sliding seat 3. Since the space between adjacent blocking protrusions 5 shrinks in the direction away from the roll body 2, after the sliding seat 3 is slid into the chute 21, the sliding seat 3 can be prevented from detaching from the roll body 2 in the radial direction.
[0021] In this embodiment, the principle of the locking sleeve 4 for axially limiting the brush strip 1 is that installation grooves 41 with the notch facing outwards are provided on both sides of the locking sleeve 4. A slidable pressing block 6 is provided in the installation groove 41. A pressing spring 7 is provided between the pressing block 6 and the bottom of the installation groove 41. One end of the pressing spring 7 is fixed to the pressing block 6 and the other end is fixed to the bottom of the installation groove 41. There are multiple pressing springs 7 and they are evenly distributed in a circle. After a set of brush strips 1 are slid into the chute 21 through the sliding seats 3 at the ends, the locking sleeve 4 is sleeved on the roll body 2, so that the pressing block 6 on the side of the locking sleeve 4 facing the brush strip 1 presses against the brush strip 1, and after squeezing the pressing spring 7, the locking sleeve 4 is fixed. In this way, the pressing spring 7 formed by the extrusion can generate an axial acting force on the brush strip 1 to realize the axial limit of the brush strip 1.
[0022] In this embodiment, the fixing structure of the locking sleeve 4 is that a first threaded hole is provided on the roller body 2. The first threaded holes are multiple and arranged at intervals along the axial direction. A second threaded hole 42 that can be opposite to the first threaded hole is provided on the outer periphery of the locking sleeve 4. The second threaded hole 42 and the first threaded hole are fixed by a locking member 8. By providing multiple first threaded holes on the roller body 2, more fixing positions can be provided for the locking sleeve 4, improving the flexibility of fixing. After the locking sleeve 4 is sleeved in place, by screwing in or out the locking member 8 that forms a threaded fit with the first threaded hole and the second threaded hole 42, the disassembly and assembly of the locking sleeve 4 can be completed.
[0023] In this embodiment, a positioning groove 43 is further provided on the inner wall of the locking sleeve 4. The positioning grooves 43 are multiple and evenly distributed in a circumferential manner. A positioning block 61 adapted to the positioning groove 43 is provided on the pressing block 6. The positioning block 61 is coupled to the positioning groove 43 and can form a sliding fit therebetween. By providing the positioning block 61 and the positioning groove 43, during the process of the pressing block 6 being squeezed and moving, a sliding fit can be formed between the positioning block 61 and the positioning groove 43, thus playing a guiding role in the movement of the pressing block 6 and preventing the pressing block 6 from tilting during the movement.
[0024] This specific embodiment is only an interpretation of the present invention and does not limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
