Description

Technical Field

[0001] The utility model discloses a snow brush with a conveniently replaceable shovel head, belonging to the field of snow removal equipment. Background Art

[0002] In cold regions, snow and ice are often seen on the doors and windows of vehicles parked outdoors. Failure to remove the snow and ice will pose a hidden danger to driving safety. Therefore, there is currently a tool shovel specially used for removing ice and a snow brush for removing snow on the market. The earliest tool shovel and snow brush were relatively independent products. Later, for the convenience of consumers, manufacturers integrated the shovel head of the tool shovel into the handle of the snow brush. For example, the disclosed Chinese patent number 200820135008.9, "A vehicle ice and snow removal tool", discloses a technical solution mainly consisting of a handle, a shovel head and bristles. The shovel head and bristles are arranged at both ends of the handle. In actual use, they can be used for shoveling ice and removing snow at the same time, which brings convenience to consumers.

[0003] However, although the above-mentioned snow brush realizes the functions of serving two purposes in one, some consumers do not like this integrated structure. They need the two functions to be used simultaneously and separately. In addition, the shovel head cannot be repaired or replaced during use, which easily leads to a waste of resources and inconvenience in use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a snow brush with a conveniently replaceable shovel head.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0013] Furthermore, the sliding plate, the protective plate, the limiting plate and the protrusion are an integrated structure.

[0014] Beneficial effects of the utility model:

[0015] Through the design of the connecting mechanism one, when the shovel head needs to be replaced, the end of the guide column on the new shovel head is inserted into the guide groove on the grip, the external threaded ring is aligned with the thread groove on the grip, and then the ring is rotated to make the external threaded ring and the thread groove threaded together. In the process of the external threaded ring being screwed into the thread groove, the guide column will be driven to be inserted into the guide groove, thereby connecting the shovel head to the grip. Moreover, the shovel head moves linearly and docks together during the connection process with the grip, avoiding the existing rotational connection method, which will cause the shovel head to be connected to the grip crookedly, which is inconvenient to use.

[0016] Through the design of the second connecting mechanism, when the brush head needs to be replaced, the protrusion is pressed to make the protrusion move in the movable opening. The protrusion will drive the sliding plate to move while moving, and the movement of the sliding plate will drive the limit plate and the protective plate to move. The limit plate moves and is stored in the inner cavity, releasing the limit on the end of the connector, and then the connector can be pulled out of the connector slot for replacement.

[0017] Through the design of the protective plate, during the use of the device, the protective plate always blocks the movable opening, thereby preventing external water and dust from entering the inner cavity and causing damage to the spring.

[0018] The design of the guide column and the guide groove can ensure that the shovel head and the handle are connected in a straight line, so that the connection between the shovel head and the handle and the rotational thread connection between the external thread ring and the thread groove do not affect each other.

[0019] By designing that the limit plate, the sliding plate and the protective plate are located in the same horizontal plane, the protective plate can block the movable opening when the device is in normal use, and the protective plate can block the movable opening when the brush head is disassembled and replaced.
