The beneficial effects of the utility model are as follows:
according to the utility model, the detachable dust cover is assembled on the head of the shell, so that the heat dissipation effect inside the electric tool is ensured on the premise of playing a role in dust prevention, and meanwhile, the detachable design is convenient for cleaning and maintenance of the dust cover, and the dust cover is simple in structure and convenient to install.
Drawings
FIG. 1 is a schematic diagram of a housing of the present utility model.
FIG. 2 is a schematic diagram showing a sectional state of the present utility model.
Fig. 3 is an enlarged schematic view at D in fig. 2.
Detailed Description
The utility model is described in further detail below with reference to the attached drawings and detailed description:
referring to fig. 1-3, the dust-proof structure of the detachable electric tool includes a housing 1, an output shaft 2 is disposed on the housing 1, specifically, one end of the output shaft 2 is located inside the housing 1, and the other end extends to the outside of the housing 1.
In this embodiment, the head end of the casing 1 includes a main opening 11 for installing the output shaft 2 and an installation groove 12 formed on the outer periphery of the main opening 11, an installation head 13 is disposed between the main opening 11 and the installation groove 12, and the dust cover 3 is detachably installed at the installation head 13, as shown in fig. 1 after installation.
As shown in fig. 2, the dust cap 3 includes an inner U-shaped passage 31 as an intermediate passage; one end of the inner U-shaped channel 31 is communicated with the output shaft 2 and the gap between the inner walls of the shell 1 to serve as an inner end channel 32; the other end of the inner U-shaped channel 31 communicates with the gap between the dust cap 3 and the mounting groove 12 as an outer end channel 33.
The outer end channel, the middle channel and the inner end channel are sequentially communicated to form a labyrinth type channel, so that a dustproof effect is achieved, meanwhile, the channel can be used as a heat dissipation channel, and heat inside the electric tool can be dissipated through the channel.
In this embodiment, the dust cap 3 is mounted on the mounting head 13 in an interference fit, a clamping fit or a rotation fit.
In order to further improve the dustproof effect, in this embodiment, a sealing ring 4 is disposed at the inner opening of the heat dissipation channel in the head of the casing 1, as shown in fig. 2, a built-in groove is formed on the inner wall of the casing 1, the sealing ring 4 is mounted at the built-in groove, a larger gap is formed between the sealing ring 4 and the output shaft 2, the output shaft 2 does not affect the sealing ring, and the sealing ring can be specifically a wool ring.
In this embodiment, a plurality of bearings 5 are disposed between the output shaft 2 of the electric tool and the inner wall of the head of the casing 1, and the bearings 5 not only can be used to cooperate with the output shaft 2 to form a rotary support for the output shaft, but also can be used as a dust-proof member to further improve the dust-proof effect.
As one of the embodiments, the outer vertical surface of the dust cover 3 is flush with the outer vertical surface of the head of the casing 1, so that the whole is more attractive.
As shown in fig. 1, the tail of the casing 1 may be provided with a detachable dust cover 6, and the dust cover 6 has a plurality of heat dissipation holes 61, and the heat dissipation holes 61 may be in a strip shape.
The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
