DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-5 As shown, an electric tractor battery fastening device includes a tractor support plate 1, a horizontal clamping mechanism 2 is arranged above the tractor support plate 1, and a vertical clamping mechanism 3 is arranged above the horizontal clamping mechanism 2; the horizontal clamping mechanism 2 includes a lower limit frame 201, an extension member 208 is fixedly connected to the middle of the front of the lower limit frame 201, and a rotating member 203 is rotatably connected to the top of the extension member 208, and push grooves 204 are opened on the inner walls of both ends of the rotating member 203, and the length direction of the two push grooves 204 is consistent with the length direction of the rotating member 203; wherein , a connecting rod 1 205 is slidably connected to one side of the inner wall of the lower limit frame 201, and a connecting rod 206 is slidably connected to the other side of the inner wall of the lower limit frame 201, and the ends of the connecting rod 1 205 and the connecting rod 206 close to the extension piece 208 are both passed through the lower limit frame 201, and the ends of the connecting rod 1 205 and the connecting rod 206 located on the outside of the lower limit frame 201 are both bent vertically upward; wherein, the inner side of the push groove 204 on one side is slidably connected to the end of the connecting rod 1 205 at the bending point, and the inner side of the connecting rod 1 205 on the other side is slidably connected to the end of the connecting rod 2 206 at the bending point, such as Figure 4-Figure 5 As shown, when the rotating member 203 rotates, the push grooves 204 on both sides respectively control the connecting rod 1 205 and the connecting rod 2 206 to move in different directions;

[0029] The front side of the inner wall of the lower limit frame 201 is slidably connected with a second clamping plate 210, and the back side of the inner wall of the lower limit frame 201 is slidably connected with a first clamping plate 209. The first clamping plate 209 and the second clamping plate 210 are fixedly connected with a lower pad 211 on one side close to the center of the lower limit frame 201. The length direction of the first clamping plate 209 and the second clamping plate 210 is consistent with the length direction of the lower limit frame 201. Figure 5 As shown, the lower pad 211 is made of rubber material to prevent the first clamping plate 209 and the second clamping plate 210 from directly acting on the surface of the battery and causing damage.

[0030] One end of the side of the clamp plate 209 is fixedly connected to the connecting rod 1 205, and the inner wall of the other end of the clamp plate 209 is sleeve-connected to the connecting rod 206. One end of the side of the clamp plate 210 is fixedly connected to the connecting rod 206, and the inner wall of the other end of the clamp plate 210 is sleeve-connected to the connecting rod 1 205. The back of the lower limit frame 201 and one end close to the connecting rod 206 is fixedly connected with a sleeve 202, and the inner wall of the sleeve 202 is movably connected with a screw rod 207. Both ends of the screw rod 207 pass through the sleeve 202 and the surfaces are threadedly connected with fastening bolts 212. One end of the screw rod 207 passes through the lower limit frame 201 and is fixedly connected to the connecting rod 206. Figure 3-Figure 4As shown, the fastening bolts 212 in the tightened state on both sides of the screw rod 212 limit their own movement, thereby limiting the movement of the second connecting rod 206, so that the rotation of the rotating member 203 is blocked, and the first connecting rod 205 cannot move;

[0031] The vertical clamping mechanism 3 includes an upper limit frame 301, the bottom of the upper limit frame 301 is fixedly installed with the top of the lower limit frame 201, and the length and width of the bottom surface of the upper limit frame 301 are slightly smaller than the length and width of the top surface of the lower limit frame 201, and the middle of the front and back of the lower limit frame 201 are fixedly installed with limit blocks 302, and the length direction of the limit blocks 302 is perpendicular to the length direction of the lower limit frame 201. The outer wall of the upper limit frame 301 is symmetrically rotatably connected with a rotating frame 303 on both sides, and the bottom surfaces of the rotating frames 303 on both sides are in active contact with the lower limit frame 201. The rotating frame 3 03 is slidably connected with an extrusion plate 304, one end of the side wall of the extrusion plate 304 is fixedly connected with a telescopic rod 305, the other end of the telescopic rod 305 passes through the rotating frame 303 and is fixedly connected with a clamping plate 307, the side of the clamping plate 307 close to the rotating frame 303 is fixedly connected with an upper pad 308, the other side of the clamping plate 307 is fixedly connected with a pull rod 309, and a spring 306 is sleeved on the outer side of the telescopic rod 305, one end of the spring 306 is fixedly connected to the extrusion plate 304, and the other end of the spring 306 is fixedly connected to the inner wall of the rotating frame 303, such as Figure 1 As shown, under the support and obstruction of the lower limit frame 201 and the limit block 302, the rotating frame 303 can only rotate 90 degrees.

[0032] The working principle of this utility model:

[0033] When the device is in use, the battery is inserted from the inside of the upper limit frame 301, and after ensuring that the bottom of the battery contacts the bottom of the lower limit frame 201, the rotating member 203 is rotated above the extension member 208, during which the push groove 204 pushes and pulls the connecting rod 1 205 and the connecting rod 2 206 on both sides respectively, so that the connecting rod 1 205 drives the clamping plate 1 209 to move toward the rotating member 203, and the connecting rod 206 drives the clamping plate 210 to move away from the rotating member 203, so that the distance between the clamping plate 1 209 and the clamping plate 210 is reduced, and the side of the battery is clamped by the lower pad 211. When fixing, tighten the fastening bolts 212 on the surface of the screw 207 and located on both sides of the sleeve 202;

[0034] Secondly, the holding column pull rod 309 pushes the clamping plate 307 to rotate and move to the top of the battery. During this period, the distance between the clamping plate 307 and the rotating frame 303 can be increased through the pull rod 309. At this time, the telescopic rod 305 is partially deep in the rotating frame 303, and the extrusion plate 304 pushes the spring 306 to shrink it. After the clamping plate 307 moves to the top of the battery, the pull rod 309 is gradually released, and the spring 306 pushes the extrusion plate 304 to return to its original position, thereby driving the clamping plate 307 to fall and be fixed close to the top of the battery.

[0035] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
