Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1 and fig. 2, the utility model provides an anti-drop charging gun 1, which comprises a movable sleeve 7 sleeved on the front part of the charging gun 1 and capable of moving along the extending direction of the charging gun 1, a sucker 10 fixed on the periphery of the movable sleeve 7 and arranged near the end part of the movable sleeve 7, a limiting seat 6 arranged on the charging gun 1 and positioned at the rear side of the movable sleeve 7, and a press plug structure arranged in the middle of the limiting seat 6; a pressing space with two ends respectively communicated with the outside air is formed among the movable sleeve 7, the sucking disc 10 and the charging gun 1; a sealing sleeve 14 which is used for extending into the movable sleeve 7 to seal one end of the pressing space is fixed on one side of the limiting seat 6, which is opposite to the movable sleeve 7; the sealing sleeve 14 is annularly arranged on the charging gun; the radial dimension of one end of the sealing sleeve 14 close to the movable sleeve is matched with the radial dimension of the inner wall of the movable sleeve; a pressing channel for communicating the outside of the movable sleeve 7 with a pressing space is arranged on the side wall of the movable sleeve 7; the press plug structure is movably arranged in the press channel along the extension direction of the press channel, and one end of the press plug structure extends out of the movable sleeve 7; one end of the press plug structure extending into the movable sleeve 7 is provided with a sealing ring 13 to seal the press channel.
Wherein, in rifle 1 is connected to charging pile 3 by electrified line 2, electrified line 2 is connected in charging box that is equipped with in charging pile 3 through a flexible motor telescopic in order to obtain the direct current. The limiting seat 6 and the movable sleeve 7 are annular, the limiting seat 6 can be fixedly or adjustably mounted on the charging gun 1 through a common connecting component, and the inner diameter of the movable sleeve 7 is larger than the front part of the charging gun 1. Preferably, still be equipped with the visor that is used for preventing the movable sleeve 7 roll-off rifle 1 in the front portion of rifle 1 that charges, the inside and the 6 periphery screw threads of spacing seat of visor match, need take off the visor by oneself when using. The seal cover 14 is elastic material, for example rubber to along the movable sleeve 7 to spacing seat 6 direction external diameter crescent, along with the movable sleeve 7 charging gun 1 that impresses, the partly part that lies in outside the movable sleeve 7 after stretching into the movable sleeve 7 of seal cover 14 offsets with the movable sleeve 7 inside wall, improves the sealed effect between movable sleeve 7 and the sealing washer 13. Spacing seat 6 passes through welded fastening on rifle 1 charges, and when spacing seat 6 offseted with movable sleeve 7, spacing seat 6 matches with the socket part that charges with rifle 1 insertion of the distance of sucking disc 10, makes sucking disc 10 compress tightly the effect of automobile body 8 better. When the press plug structure extends out of the press channel, a sealing ring 13 on the press plug structure is abutted against the inner side wall of the movable sleeve 7, so that the press channel is sealed; when the press plug structure is pressed into the pressing channel, the sealing ring 13 is separated from the inner side wall of the movable sleeve 7, so that the pressing space is communicated with the outside through the pressing channel.
When filling electric pile 3 uses, in inserting the socket that charges on the automobile body 8 with 1 front end of rifle that charges, because the thrust of automobile body 8 surface to sucking disc 10, sucking disc 10 drives movable sleeve 7 and removes to spacing 6 directions to make seal cover 14 on the spacing seat 6 stretch into from 7 one end of movable sleeve, thereby 8 surfaces of automobile body and seal cover 14 have realized the sealed at 7 both ends of movable sleeve, prevent that rifle 1 that charges from droing from automobile body 8. Moreover, because the sealing washer 13 of the structure of the tamponade has realized the sealed to pressing the passageway, after charging and accomplishing, press in pressing the passageway through the tamponade structure, sealing washer 13 breaks away from the inside wall of movable sleeve 7, makes the space of pressing communicate with pressing the passageway, presses the pressure in the space to reduce, and sucking disc 10 can easily be taken off from automobile body 8 to extract charging gun 1.
As shown in fig. 3, when anti-drop charging gun 1 is not used, preferably, a plug board is horizontally fixed on charging pile 3, a mounting hole matched with the front end of charging gun 1 is formed in the plug board, protection shell 5 is fixed at the bottom of the plug board, and charging gun 1 is inserted into the mounting hole from top to bottom, so that the front end of charging gun 1 is located inside protection shell 5. The sucking disc 10 on the rifle 1 that charges adsorbs on baffle 4, and is the same with the connected mode of rifle 1 and automobile body 8 that charges in the aforesaid to prevent the safety problem that the rifle 1 rainwater that charges gets into and lead to.
As shown in fig. 2, an enlarged cross-sectional view of a portion a in fig. 1, the press plug structure includes a slider and a press piece 11; the sliding piece is arranged at the front part of the charging gun 1 in a sliding manner along the extension direction of the charging gun 1; the pressing piece 11 is arranged in the pressing channel in a sliding mode, one end of the pressing piece extends out of the movable sleeve 7, and one end of the pressing piece 11 extends into the movable sleeve 7 and is elastically connected with the sliding piece.
Wherein, the sliding part can be a tubular sliding sleeve which is sleeved on the charging gun 1 or a block. The pressing piece 11 extends into the space between one end of the movable sleeve 7 and the sliding piece and is connected with a pressing spring. Under the action of the elastic force of the pressing spring, the pressing piece 11 extends out of the movable sleeve 7, and the sealing ring 13 abuts against the inner side wall of the movable sleeve 7 to seal the pressing channel.
The front portion of the charging gun 1 is provided with a sliding rail arranged along the extending direction of the charging gun 1, and the sliding part is matched with the sliding rail in a sliding manner. The sliding piece and the pressing piece 11 are driven to synchronously slide through the sliding rail, so that the movable sleeve 7 slides more stably; and through slide rail length setting, prevent that the movable sleeve 7 from shifting out outside rifle 1 charges.
The two press plug structures are oppositely arranged on the movable sleeve 7. Through two relative settings of tamponade structures, prevent that the movable sleeve 7 from rocking to accelerate gas outgoing, the rifle 1 of being convenient for takes off automobile body 8.
A compression spring 9 is further sleeved outside the sealing sleeve 14; two free ends of the compression spring 9 are respectively fixedly connected with the limiting seat 6 and the opposite surface of the movable sleeve 7. The pressure spring 9 is arranged between the limiting seat 6 and the movable sleeve 7, and the sucker 10 is abutted against the vehicle body 8 due to the rebounding force of the pressure spring 9 compressed by the movable sleeve 7, so that the sealing performance of the sucker 10 is improved.
The rifle 1 that charges is gone up and is equipped with screw thread portion along the extending direction, screw thread portion matches with spacing seat 6. Adjust spacing seat 6 through setting up screw thread portion, be more convenient for adapt to different sockets that charge. And guarantee the sealed effect of seal cover 14 and through rotatory opening seal cover 14 accelerate the air escape in the space of pressing, prevent the problem that rifle 1 can't take out under the condition of tamponade structural damage.
The above embodiments are only used for illustrating the technical solutions of the present invention, but not for limiting, and the technical solutions of the present invention can be modified or equivalently replaced, and all of them should be covered in the scope of the claims of the present invention.
