Description

Technical Field

[0001] This utility model relates to the field of snow brush technology, and in particular to a modular, easy-to-disassemble snow brush. Background Technology

[0002] A snow brush is a common household tool specifically designed for snow removal, improving the efficiency of snow clearing. A snow brush typically consists of a brush head and a handle; the user operates the brush head by holding the handle. In conventional snow brushes, the brush head and handle are usually integrated. When the bristles on the brush head become worn and shortened due to friction, the entire snow brush becomes unusable. However, in actual use, the bristles on the brush head often experience significant localized wear. Because this affects snow removal efficiency, the entire snow brush often has to be discarded, resulting in considerable material waste.

[0003] To improve the utilization rate of snow brushes, snow brushes with detachable and replaceable brush heads and handles have appeared on the market. When a snow brush head malfunctions, simply replacing it restores normal working performance. While this type of snow brush improves utilization to some extent, the utilization rate of the brush head itself is still not high enough, resulting in considerable material waste. The overall utilization rate of snow brushes still needs to be improved. Utility Model Content

[0004] To overcome the technical problem of low utilization rate of existing snow brushes, this utility model provides a modular, easy-to-disassemble snow brush.

[0005] To achieve the above objectives, this utility model proposes a modular, easily detachable snow brush, comprising a bracket and a brush head. The brush head includes a brush plate and brush strips. One side of the brush plate is fixedly connected to the bracket, and the other side is provided with multiple detachably connected brush strips, which are evenly distributed. The bracket includes a support rod and a guide rod. One end of the support rod is fixedly connected to the brush plate, and the other end is detachably connected to the guide rod.

[0006] Furthermore, the brush plate has multiple evenly spaced guide grooves, and the brush strips have guide blocks that match the guide grooves. One end of each guide groove is open, and the other end is closed. The closed end has a first opening corresponding to each guide groove, and multiple brush strips have a first buckle on the side near the closed end.

[0007] Furthermore, the brush plate is provided with a detachable fixing strip, which includes a column and a disc. One end of the column is provided with an integrated disc, and the other end passes through the guide block and the brush plate. The guide block and the brush plate are respectively provided with grooves and fixing slots that match the column.

[0008] Furthermore, the end of the column near the disc is provided with a first threaded head, and the fixing groove is provided with a first threaded hole at the end of the threaded head.

[0009] Furthermore, the guide rod has a second threaded head at one end near the support rod, and the support rod has a second threaded hole that mates with the second threaded head.

[0010] Furthermore, the guide rod has a polygonal cross-section, and a detachable shovel head is provided at the end of the guide rod away from the support rod. A protective sleeve is provided on the outer surface area of ​​the guide rod between the shovel head and the support, and the protective sleeve has a polygonal hole that matches the guide rod.

[0011] Furthermore, the shovel head and the end of the support rod near the sheath are equipped with limiting rings, and elastic plates are provided between the two ends of the sheath and the limiting rings.

[0012] Furthermore, the guide rod has multiple spring pieces on its circumference near the end of the shovel head. One end of each spring piece is integrated with the guide rod, and the other end of each spring piece is provided with a second buckle. The shovel head has a second opening that cooperates with the second buckle.

[0013] Furthermore, the shovel head includes a connecting cylinder, one end of which is provided with a polygonal opening for engaging the guide rod, and the side wall of the connecting cylinder is provided with multiple second openings in the circumferential direction for engaging the second buckle.

[0014] Furthermore, a positioning groove is provided at one end of the guide rod near the connecting cylinder, and a spring is provided in the positioning groove. The length of the spring is 3cm-5cm greater than the depth of the positioning groove. One end of the spring contacts the bottom of the positioning groove, and the other end contacts the bottom of the connecting cylinder.

[0015] The beneficial effects of this invention are as follows: multiple detachable brush strips are distributed in multiple areas of the brush. When the bristles in a certain area are severely worn, the snow removal effect of the brush head can be restored by replacing the corresponding brush strip, without replacing the entire brush head, thus improving the utilization rate of the brush head. When the brush head suffers irreparable damage, the entire brush head can be replaced by removing the support rod from the guide rod, thereby ensuring the snow removal effect of the entire snow brush.

Detailed Implementation

[0028] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0029] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-9As shown, this utility model proposes a modular, easily detachable snow brush, including a bracket 1 and a brush head. The brush head includes a brush plate 11 and brush strips 2. One side of the brush strips 2 is detachably connected to the brush plate 11, and the other side is provided with bristles 22. One side of the brush plate 11 is fixedly connected to the bracket 1. Multiple brush strips 2 are evenly distributed on the brush plate 11. With the spacing design of the guide grooves 111, the connection between the brush strips 2 and the brush plate 11 is ensured to be stable and reasonably distributed, thereby achieving uniform cleaning force during snow sweeping and avoiding insufficient cleaning or excessive wear in some areas. The brush plate 11 is provided with multiple evenly spaced guide grooves 111, and the brush strips 2 are provided with guide blocks 21 that cooperate with the guide grooves 111. One end of the guide groove 111 is an open end, and the other end is a closed end. When installing the brush strips 2, the guide blocks 21 are slid into the guide grooves 111 along the open end and finally fit into the closed end. The closed end has a first opening 112 corresponding to each guide groove 111. Multiple brush strips 2 have a first buckle 212 on the side near the closed end. The first buckle 212 engages with the first opening 112, completing the initial fixation of the brush strip 2 to the brush plate 11. Through the sliding cooperation between the guide groove 111 and the guide block 21, the brush strip 2 can quickly slide into or out of the brush plate 11. The buckle structure at the closed end further achieves initial fixation, allowing for disassembly and assembly without the need for specialized tools, significantly improving maintenance efficiency. As an independently detachable component, when some brush strips 2 are worn or damaged, it is not necessary to replace the entire snow brush; only the corresponding brush strip 2 needs to be replaced, reducing material waste and maintenance costs.

[0031] The brush plate 11 is provided with a detachable fixing strip 14, which includes a column 141 and a disc 143. One end of the column 141 has an integrated disc 143, and the other end passes through the guide block 21 and the brush plate 11. The guide block 21 and the brush plate 11 are respectively provided with a groove 211 and a fixing groove 113 that mate with the column 141. As the fixing strip 14 passes through the brush plate 11 and the guide block 21, multiple brush strips 2 are further fixedly connected to the brush plate 11 through the same fixing strip 14. Multiple brush strips 2 are simultaneously fixed by a single fixing strip 14, which reduces the number of parts and assembly complexity, ensures a stable connection between each brush strip 2 and the brush plate 11, and prevents the brush strips 2 from detaching from the brush plate 11 when subjected to large external forces. The end of the column 141 near the disc 143 is provided with a first threaded head 142, and the fixing groove 113 is provided with a first threaded hole 1411 corresponding to the end of the first threaded head 142. The engagement of the first threaded head 142 with the first threaded hole 1411 secures the fixing strip 14 within the fixing groove 113, preventing it from becoming loose and ensuring its tightness over the multiple brush strips 2. The user can operate the disc 143 to rotate the fixing strip 14 or to remove or insert it into the brush plate 11.

[0032] The bracket 1 includes a support rod 12 and a guide rod 13. One end of the support rod 12 is fixedly connected to the brush plate 11, and the other end is detachably connected to the guide rod 13. The guide rod 13 has a second threaded head near the end of the support rod 12, and the support rod 12 has a second threaded hole that mates with the second threaded head. By controlling the relative rotation of the support rod 12 and the guide rod 13, the support rod 12 can be installed onto or separated from the guide rod 13. The detachable connection between the support rod 12 and the guide rod 13, combined with the fixed connection between the brush plate 11 and the bracket 1, achieves a modular design for the bracket 1. This design allows users to quickly disassemble or replace the entire brush head without having to replace the entire bracket 1 due to brush head damage, significantly improving the utilization rate and ease of maintenance of the snow brush.

[0033] The guide rod 13 has a polygonal cross-section. A detachable shovel head 3 is located at the end of the guide rod 13 furthest from the support rod 12. A sheath 4 is provided on the outer surface of the guide rod 13 between the shovel heads 3 and the support rod 12. The sheath 4 has polygonal holes 42 that mate with the guide rod 13. The engagement of the polygonal holes 42 with the guide rod 13 prevents relative rotation between the sheath 4 and the guide rod 13. Limiting rings 313 are provided at the ends of both the shovel head 3 and the support rod 12 near the sheath 4. Elastic plates 132 are provided between both ends of the sheath 4 and the limiting rings 313. When the shovel head 3 is assembled onto the guide rod 13, the limiting rings 313 at both ends of the sheath 4 apply an axial compressive force to the sheath 4 to ensure that the position of the sheath 4 remains stable in the axial direction of the guide rod 13. The sheath 4 is generally made of elastic rubber. When the sheath 4 is interference-fitted onto the guide rod 13, it applies a reaction force to both the guide rod 13 and the shovel head 3 to ensure a tight fit between the guide rod 13 and the shovel head 3. The sleeve 4 has multiple evenly spaced annular grooves 41211 along its length, which increases the contact area between the user's hand and the sleeve 4 when using the snow brush, allowing the user to grip the snow brush well.

[0034] The guide rod 13 has multiple spring pieces 131 arranged circumferentially near the plug end. One end of each spring piece 131 is integrated with the guide rod 13, and the other end of each spring piece 131 has a second latch 1311. The shovel head 3 has a second opening 311 that engages with the second latch 1311. The guide rod 13 has a slot in the radial direction corresponding to the position of the spring piece 131, which facilitates the deformation of the spring piece 131 relative to the radial direction of the guide rod 13. When the shovel head 3 is assembled onto the guide rod 13, the spring piece 131 deforms into the slot until the second latch 1311 is inserted into the second opening 311, causing the spring piece 131 to spring back, forming a fixed connection between the guide rod 13 and the shovel head 3. The shovel head 3 includes a connecting cylinder 31. One end of the connecting cylinder 31 has a polygonal opening 312 that engages with the guide rod 13. Through the engagement of the polygonal opening 312 with the guide rod 13, the shovel head 3 and the guide rod 13 maintain a stable relative circumferential position. The side wall of the connecting cylinder 31 is provided with multiple second openings 311 that engage with the second buckles 1311 in the circumferential direction. The multiple second buckles 1311 and the multiple second openings 311 form a cooperating relationship, forming a stable engagement between the guide rod 13 and the shovel head 3.

[0035] The guide rod 13 has a positioning groove 1331 at one end near the connecting cylinder 31. A spring 133 is installed in the positioning groove 1331, with one end of the spring 133 contacting the bottom of the positioning groove 1331 and the other end contacting the bottom of the connecting cylinder 31. When the guide rod 13 is inserted into the positioning groove 1331, the spring 133 is compressed, and under the action of elastic deformation force, the guide rod 13 and the connecting cylinder 31 fit tightly. When disassembling the guide rod 13, the spring piece 131 is pressed radially upward through the second opening 311 to deform it, causing the second latch 1311 to disengage from the second opening 311. At this time, under the elastic force of the spring 133, the guide rod 13 automatically disengages from the connecting cylinder 31, allowing the bracket 1 to quickly separate from the shovel head 3, improving the ease of separation of the shovel head 3. The length of spring 133 is 3cm-5cm greater than the depth of positioning groove 1331. If the length of spring 133 extending out of positioning groove 1331 is too short, it is difficult to form sufficient elastic force. If the length of spring 133 extending out of positioning groove 1331 is too long, the depth requirement of connecting cylinder 31 is too high, which is inconvenient to use.

[0036] The working principle of this utility model is as follows: When a portion of the bristles 22 on the brush plate 11 is severely damaged, the fixing strip 14 is pulled out of the brush plate 11, and the first buckle 212 on the brush strip 2 corresponding to the severely damaged area is engaged, causing the corresponding brush strip 2 to slide out of the brush plate 11 along the guide groove 111, and a new brush strip 2 is then replaced. The entire brush head can be replaced using the detachable support rod 12 and guide rod 13, and the detachable scraper head 3 also facilitates the replacement of a new scraper head 3.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
