DETAILED DESCRIPTION
[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0045] like Figures 1 to 15 As shown, the lead-acid battery charging device of the present invention comprises a charging platform 1, a fixing seat 2 and a control switch assembly 3. The fixing seat 2 is used to place the lead-acid battery, and the fixing seat 2 is installed on the charging platform 1. A fixing area 4 is provided in the middle of the fixing seat 2, and the battery can be placed in the fixing area 4 for positioning, so as to facilitate charging. The control switch assembly 3 is used to control the discharge of the connection terminal 5, and the control switch assembly 3 is installed on the charging platform 1.
[0046] A bracket 6 is provided on the charging station 1, and a first sliding component 7, a second sliding component 8 and a third sliding component 9 are provided on the bracket 6. The first sliding component 7 is vertically arranged with the second sliding component 8, the second sliding component 8 is installed on the first sliding component 7, and the third sliding component 9 is vertically installed on the second sliding component 8. A connecting terminal 5 is provided at the lower end of the third sliding component 9.
[0047] The first sliding assembly 7 enables the connection terminal 5 to move forward and backward, the second sliding assembly 8 enables the connection terminal 5 to move left and right, and the third sliding assembly 9 enables the connection terminal 5 to move up and down. When the battery is placed in the fixed area 4, the connection terminal 5 can be moved so that the connection terminal 5 can contact the electrode on the battery to achieve charging.
[0048] After the battery is manufactured, it needs to be charged. There are often many workers in the factory. If they are not careful, they may accidentally touch the switch, which poses a certain safety hazard. The control switch component 3 in the present application can avoid such a situation. The control switch component 3 can be rotated or pushed first, and then pushed or rotated again to achieve contact between the first electrode 10 and the second electrode 11, so as to power the connection terminal 5.
[0049] The control switch assembly 3 includes a mounting seat 12, a sliding member 13, a handle 14, a first electrode 10, a second electrode 11 and an outer cover 15. The handle 14 can push the sliding member 13 to slide in the middle of the mounting seat 12. When the handle 14 is rotated, the first electrode 10 can be driven to rotate, so that the first electrode 10 and the second electrode 11 are in contact in the notch 16. The handle 14 is rotated and pushed to keep the spring 17 compressed, so that the first electrode 10 and the second electrode 11 are in contact in the notch 16.
[0050] If one of the rotation or pushing operations is not performed, the first electrode 10 and the second electrode 11 will not contact each other in the notch 16, thereby preventing the switch from being accidentally closed.
[0051] A cylinder 18 is disposed on the mounting seat 12 . The cylinder 18 is hollowed out to form a through hole 19 . A notch 16 is disposed on the cylinder 18 . The notch 16 is used for the first electrode 10 and the second electrode 11 to contact each other.
[0052] In addition, a blocking portion 20 is provided at the upper end of the cylinder 18 . The blocking portion 20 protrudes toward the middle and is used to block the sliding member 13 to prevent the sliding member 13 from being pushed out of the through hole 19 under the elastic force of the spring 17 .
[0053] The sliding member 13 is installed inside the through hole 19. To prevent the sliding member 13 from rotating together with the handle 14, a positioning column (not shown in the figure) can be provided on the cylinder 18. The positioning column passes through the cylinder 18 and extends to the sliding member 13. A vertical strip groove (not shown in the figure) is provided on the sliding member 13, and the positioning column is placed in the strip groove. Therefore, the sliding member 13 can only slide up and down under the restriction of the positioning column, and cannot rotate together with the handle 14.
[0054] The middle of the sliding member 13 is hollowed out to form a mounting hole 21 , and the first electrode 10 is disposed in the mounting hole 21 , so that the first electrode 10 can slide up and down along with the sliding member 13 , and the movable portion 24 on the first electrode 10 can rotate along with the handle 14 .
[0055] The sliding member 13 is provided with an accommodating opening 22, the distance between the surface a of the accommodating opening 22 and the communicating opening 23 is shorter, and the distance between the surface b and the communicating opening 23 is longer, so that when the handle 14 drives the movable part 24 to rotate, the part holding the movable part 24, the first elastic arm 25 and the second elastic arm 26 can rotate toward the surface b and deflect a certain angle. After the eccentric rod 32 rotates 90°, the first elastic arm 25 and the second elastic arm 26 will also return to their original positions.
[0056] A first blocking ring 27 is provided at one end of the receiving opening 22, and a second blocking ring 28 is provided at the other end. The first blocking ring 27 is used to cooperate with the blocking portion 20, and the blocking portion 20 blocks the first blocking ring 27, thereby preventing the sliding member 13 from sliding out of the through hole 19. The second blocking ring 28 is used to compress the spring 17.

[0059] A blocking piece 35 is provided on the eccentric rod 32 , and the blocking piece 35 is installed on the eccentric rod 32 through a limiting pin 36 .
[0060] The reset member 29 is composed of a first mounting foot 37 , a second mounting foot 39 and a spiral portion 40 . The first mounting foot 37 and the second mounting foot 39 are connected via the spiral portion 40 .

The first mounting foot 37 is mounted on the cylinder 18, and the second mounting foot 39 is mounted on the rotating portion 31.
[0062] When the first electrode 10 and the second electrode 11 need to contact each other, the reset member 29 is driven to rotate by the handle 14, so that the second mounting foot 39 is driven to rotate, while the first mounting foot 37 on the cylinder 18 does not rotate.
[0063] A spiral portion 40 is provided on the reset member 29 and can be compressed, so that the handle 14 can push the sliding member 13 to slide.
[0064] The first electrode 10 is installed in the sliding member 13 , one end of the first electrode 10 is fixed on the sliding member 13 , and the other end of the first electrode 10 is movably connected to the eccentric rod 32 .

A fixing opening 46 for fixing the positioning portion 41 is also provided in the mounting hole 21.
[0067] The movable portion 24 is provided with an opening 47 , and the eccentric rod 32 is located in the opening 47 . When the eccentric rod 32 is placed in the opening 47 , the eccentric rod 32 is rotated by the handle 14 , so that the eccentric rod 32 can move in the opening 47 .
[0068] like Fig.15 As shown, when the rotating part 30 rotates in the direction F, the eccentric rod 32 is at the edge of the opening 47. After the rotating part 30 drives the eccentric rod 32 to rotate 90°, the eccentric rod 32 can enter the center of the opening 47, that is, position c. The rotating eccentric rod 32 can drive the movable part 24 to pull downward, so that the horizontal part 42 is separated from the notch 16, and the first electrode 10 and the second electrode 11 are kept disconnected.
[0069] The outer cover 15 is arranged on the mounting seat 12, and the second electrode 11 is arranged inside the outer cover 15, and the second electrode 11 contacts the first electrode 10, and the second electrode 11 is composed of a rod body 48 and a limiting body 49, and the limiting portion 43 is arranged in an arc shape, and a limiting opening 50 for accommodating the limiting body 49 is arranged on the limiting portion 43, and extrusion portions 51 are arranged at both ends of the limiting opening 50.
