Example 1

The electromagnetic lock sealing structure for the charging gun with high sealing effect is described in detail with reference to fig. 1 to 5.

The sealing structure is described in detail with reference to fig. 1-2.

The electromagnetic lock sealing structure includes a housing 100 for accommodating an electromagnetic lock, an electromagnetic lock body 200 accommodated in the housing 100, an electromagnetic lock push rod 201 movably fitted with the electromagnetic lock body 200, and a sealing member 300 provided between the housing 100 and the electromagnetic lock body 200. The right end of the housing 100 is provided with a through hole 101 communicating with the inside thereof, and an inner top wall 102 is provided on the side of the housing 100 near the through hole 101.

Specifically, the sealing member 300 is sleeved on the push rod, and the sealing member 300 includes a base 301, a limiting portion 303, and a connecting wall 302 for connecting the limiting portion 303 and the base 301, where the base 301 of the sealing member 300 is clamped between the electromagnetic lock body 200 and the inner top wall 102 of the housing 100. The right-hand member setting of electromagnetic lock push rod 201 is in through-hole 101, is equipped with an inwards sunken annular groove 2011 at the right-hand member of through-hole 101, and the right-hand member of sealing member 300 is fixed in groove 2011 through spacing portion 303 suit, and is interference fit between spacing portion 303 and the groove 2011 to further improve the sealed effect of sealing member 300.

The whole sealing element 300 can move along with the telescopic movement of the electromagnetic lock push rod 201, namely, the connecting wall 302 and the limiting part 303 are arranged in the through hole 101, when the electromagnetic lock push rod 201 is contracted inwards, the sealing element 300 can be driven by the limiting part 303 to move inwards in a recessed mode, and therefore the sealing effect is kept.

The seal 300 of the present application is described in detail with reference to fig. 3-5.

The sealing member 300 has a hollow structure, that is, a cavity 304 is further provided in the sealing member 300, so as to reserve a space for the limiting portion 303 to be recessed inwards. An upwardly protruding projection 3011 is provided at the top edge of the base 301, and a limit slot 103 is provided on the inner top wall 102 of the housing 100 to cooperate with the projection 3011 to limit the base 301, so as to prevent the base 301 from being pulled out of the housing 100 when the electromagnetic lock push rod 201 is extended outwards.

Preferably, the convex wall 3011 and the limiting groove 103 are all annular structures, and the connecting wall 302, the base 301 and the limiting portion 303 are integrated. In order to ensure the overall sealing effect, the sealing member 300 is made of a flexible waterproof material, such as a composite polymer material having a certain elasticity under the premise of having a certain waterproof effect, such as rubber, polyurethane, acrylic acid, etc.

Specifically, the limiting portion 303 has a truncated cone-shaped structure, i.e. the cross-sectional diameter thereof gradually decreases from a side near the base 301 to a side near the recess 2011.

The sealing piece 300 which can act along with the action of the electromagnetic lock push rod 201 is arranged between the electromagnetic lock and the shell 100, compared with the prior art, the whole sealing effect of the electromagnetic lock is greatly improved, and therefore the electromagnetic lock is effectively waterproof and quite reliable.

The above examples are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the spirit and scope of the present utility model. Various modifications and improvements of the technical scheme of the present utility model will fall within the protection scope of the present utility model without departing from the design concept of the present utility model, and the technical content of the present utility model is fully described in the claims.
