Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

The charging gun is shown in fig. 1-6, the shell 1 mainly comprises two parts, namely a left shell and a right shell which are respectively shown in fig. 4 and 5, the two shells 1 are mutually spliced to form the integral structure of the charging gun, a space is formed between the left shell and the right shell for installing a circuit module for charging, and the integral spliced structure is shown in fig. 1 and 2.

The inner side of the shell 1 and the shell 1 are also integrally formed with positioning bases 11, the positioning bases 11 are positioned on the inner walls of the left and right shells 1, and the positions of the positioning bases are mirror image, so that the two positioning bases 11 can be opposite to each other; the positioning base 11 is also formed with a guide 12 extending from one side to the other, i.e., the guide 12 extends from one side to the other side, and serves to limit and protect the device located in the middle thereof.

A locking structure is installed between the two positioning bases 11.

The locking structure is shown in fig. 6, which may include a first clamping portion and a second clamping portion, where the first clamping portion is set as a first hollow positioning column 3, one end of the positioning column 3 is fixedly installed in the positioning base 11, and the inner wall of the positioning column 3 is provided with a clamping groove 31, the clamping groove 31 surrounds the inner wall of the positioning column 3, and the second clamping portion is set as a positioning rod 2, the positioning rod 2 is fixedly installed in another positioning base 11, the positioning rod 2 is provided with an elastic protrusion 22, and the positioning rod 2 can extend into the hollow of the positioning column 3 and make the elastic protrusion 22 abut against in the clamping groove 31 to form a lock.

More preferably, there are two at least stabilizer blades 21 on locating lever 2 integrated into one piece, also can set up to three or four, be circumference evenly distributed in the one end of locating lever 2, elastic bulge 22 sets up on stabilizer blade 21, stretches into in the cavity of reference column 3 through stabilizer blade 21, makes elastic bulge 22 conflict to fix in joint recess 31, sets up the purpose of stabilizer blade 21 for better emergence deformation, and every stabilizer blade 21 can have better elastic deformation ability, convenient shrink.

The locking limiting piece 4 is further installed in the hollow of the positioning column 3, the locking limiting piece is an annular piece and installed in the hollow of the positioning column 3, the installation position is deeper than the depth of the clamping groove 31, namely, the elastic protrusion 22 of the positioning rod 2 is required to extend to the position of the locking limiting piece 4 and is required to extend more towards the positioning column 3, the inner diameter of the locking limiting piece 4 is smaller than the diameter of a circle formed by the elastic protrusion 22, so that when the supporting leg 21 and the elastic protrusion 22 continue to extend into the hollow of the positioning column 3, the locking limiting piece 4 can be abutted to enter the circle center of the locking limiting piece 4, when the elastic protrusion 22 passes through the locking limiting piece 4, the end face of the elastic protrusion 22 is abutted to the end face of the locking limiting piece 4, and when the positioning column 3 and the positioning rod 2 are separated slightly forcefully, the positioning rod 2 can be pulled out of the positioning column 3 smoothly, and the elastic protrusion 22 cannot be abutted again with the clamping groove 31 because the elastic protrusion 22 is limited by the locking limiting piece 4 at the moment, so that separation between the two shells 1 can be achieved easily.

In order to better fix the locking and limiting piece 4, the locking and limiting piece 4 can be fixed in the hollow of the positioning column 3 through friction force, and the locking and limiting piece 4 can be clamped in the hollow of the positioning column 3 to a certain extent through arranging the protruding and recessed structure 41, of course, the protruding and recessed structure 41 cannot be provided with larger resistance, only in order to improve the stability of the locking and limiting piece 4, when the positioning rod 2 is separated from the positioning column 3 with the locking and limiting piece 4 by slightly forcing, the locking and limiting piece 4 can easily overcome the resistance of the protruding and recessed structure 41, so that separation is realized; when the locking and limiting piece 4 needs to be installed again, the locking and limiting piece 4 can be clamped to the protruding and recessed structure 41 only by slightly pushing the locking and limiting piece 4 with force, so that the locking and limiting piece 4 is fixed again.

Considering that the elastic bulge 22 can pass through the locking limiting piece 4 only by extrusion, the end face of the elastic bulge 22 is considered to be an inclined face, so that sliding friction is caused between the inclined face and the inner wall of the locking limiting piece 4, the structure of the locking limiting piece 4 can be set to be a round table type, the elastic bulge 22 is better convenient for the supporting leg 21 to enter, after the elastic bulge 22 is arranged, the positioning rod 2 is only required to be extruded with a little force, the supporting leg 21 and the elastic bulge 22 are driven by the positioning rod 2 to extend into the hollow part of the positioning column 3 continuously, sliding friction is caused between the positioning rod 2 and the locking limiting piece 4 until the elastic bulge 22 extends out of the end face of the locking limiting piece 4 after passing through the locking limiting piece 4, so that the locking limiting piece 4 is in abutting connection with the elastic bulge 22, and the positioning rod 2 is pulled back, so that the elastic bulge 22 is not easy to separate from the locking limiting piece 4, but the locking limiting piece 4 is directly taken out.

In order to facilitate the opening of the locking structure, a certain pressing stroke is required, so it is considered to make the housing 1 of a material having a certain elastic deformation amplitude, or to provide the housing 1 with a structure that can be pressed at the portion of the positioning base 11, that is, a structure surface that is hollow, so that the portion can be restored to the original state after being pressed.

Thus, the design of the clamping structure of the charging gun is completed; when the left shell 1 and the right shell 1 are assembled and clamped, the locking structure is positioned in the clamping stroke, so that the elastic bulge 22 of the positioning rod 2 can be just clamped into the clamping groove 31 of the positioning column 3, the right-angle end face of the elastic bulge 22 is abutted against the end face of the clamping groove 31, the positioning column 3 and the positioning rod 2 are difficult to separate, and the left shell 1 and the right shell 1 are clamped, so that separation is difficult to occur; when the two shells 1 need to be disassembled, the locking structure is needed to be opened because of the existence of the locking structure, at the moment, the positioning rod 2 continues to extend towards the hollow part of the positioning column 3 by pressing the shells 1, so that the support legs 21 drive the elastic protrusions 22 to contact the locking limiting pieces 4, right-angle end faces of the elastic protrusions 22 abut against the end faces of the locking limiting pieces 4 after passing through the locking limiting pieces 4, at the moment, the elastic protrusions 22 cannot extend into the locking grooves 31 after being limited because the diameters of the locking limiting pieces 4 are smaller than the diameters of the locking grooves 31, and therefore, no locking structure exists between the positioning rod 2 and the positioning column 3, and after the pressing of the shells 1 is released, the positioning rod 2 can be smoothly separated from the positioning column 3, so that the separation of the two shells 1 is facilitated, and at the moment, the disassembly of the shells 1 can be completed by opening other locking structures between the two shells 1, so that maintenance is performed; when the two shells 1 are required to be installed again, the locking limiting piece 4 is separated from the supporting leg 21 of the positioning rod 2 by pressing the supporting leg 21, then the locking limiting piece 4 is placed into the hollow of the positioning column 3 again, fixation is formed again through the protrusion and the concave structure 41, then the two shells 1 are clamped again, the elastic protrusion 22 of the positioning rod 2 stretches into the clamping groove 31, and connection installation between the two shells 1 is completed again.
