Detailed Description

The utility model is further described below with reference to the drawings and examples.

Referring to fig. 1-8, an assembly structure of a rear cover and a machine head, the machine head comprises a machine shell 10, a plurality of positioning jacks 111 penetrating through the front end surface of the machine shell 10 are arranged on the front end surface of the machine shell, locking inserting columns 211 are arranged on the rear cover 20 at positions corresponding to the positioning jacks 111, and a locking assembly 30 which is mutually locked with the locking inserting columns 211 is arranged in the machine shell 10.

Referring to fig. 2, 3, 5 and 8, the rear end of the locking post 211 is provided with a locking slot 212, the locking assembly 30 includes a locking member 130 movably disposed relative to the housing 10 and capable of being snapped into the locking slot 212, a spring 140 for restricting the position of the locking member 130 is disposed in the housing 10, and a pressing member 150 for pressing and triggering is further connected to the locking member 130.

Referring to fig. 2 and 8, the rear end of the locking plunger 211 is provided with a tapered guide 213, and the locking groove 212 is provided at the front side of the tapered guide 213. The tapered guide 213 is provided to enable the locking plunger 211 to be inserted into the positioning receptacle 111 during insertion. Meanwhile, in the backward plugging movement process of the tapered guide part 213, the tapered guide part 213 presses the locking piece 130, so that the locking piece 130 moves relative to the casing 10, and the locking piece 130 moves away from the rear of the positioning jack 111, and when the locking slot 212 moves backward along with the locking plunger 211, the locking piece 130 has a resetting space when the position of the locking slot 212 corresponds to the position of the locking piece 130. At this time, under the action of the spring 140, the spring 140 drives the locking member 130 to reset, so that the locking member 130 is clamped into the locking groove 212, so that the front and rear positions of the rear cover 20 are restrained by restraining the front and rear positions of the locking plunger 211 by the locking member 130, and the locking installation of the rear cover is completed.

Specifically, the locking groove 212 is a ring-shaped groove.

Preferably, the positioning insertion holes 111 and the locking posts 211 are uniformly distributed along the rotation axis of the motor 40. The positioning insertion holes 111 and the locking insertion posts 211 which are uniformly distributed circumferentially can fully enhance the connection stability of the rear cover 20 and the housing 10.

Referring to fig. 6 and 7, the locking member 130 is provided with a guide hole 131, the casing 10 is provided with a guide post 121 inserted into the guide hole 131, and the guide hole 131 is further screwed with a release preventing bolt 160 for preventing the guide post 121 from being released from the guide hole 131.

The guide post 121 plays a role of guiding and stabilizing the locking member 130 during movement, so as to ensure that the locking member 130 can move stably only in one direction.

Referring to fig. 3 and 7, the casing 10 is provided with a pressing hole 112, and the pressing member 150 is movably disposed in the pressing hole 112.

Specifically, the pressing member 150 includes a pressing portion 153, a limiting portion 152, and a connecting portion 151, where the mounting portion 153 is movably disposed in the pressing hole 112, and the limiting portion 152 is attached to the inside of the casing 10 to perform a limiting function, and the connecting portion 151 is fixedly connected to the locking member 130.

Referring to fig. 1 to 7, in the present utility model, the locking member 130 is preferably movably disposed in the following manner: the locking member 130 is disposed to move up and down with respect to the casing 10. Of course, a mode of moving left and right can also be adopted. However, the advantage of the up-and-down movement arrangement is that the pressing member 150 can be disposed at the upper or lower portion of the casing 10 during the up-and-down movement arrangement, and the erroneous touching can be avoided as much as possible in both directions.

Referring to fig. 3 and 7, the housing 10 is hollow and has an opening at the front end, an organic cover 120 is mounted at the front end of the housing 10, and the positioning insertion hole 111 is provided on the cover 120.

Referring to fig. 8, a positioning cavity 200 for accommodating the cover 120 is provided on the rear end surface of the rear cover 20.
