[0034] Example 1

[0035] See also Figure 1-Figure 10 As shown, the present embodiment provides a rotary hanging lock for an energy storage box, comprising an energy storage box corner piece 1, a lock seat 2 is arranged inside the energy storage box corner piece 1, the energy storage box corner piece 1 is fixed at the corner of the energy storage box, the energy storage box corner piece 1 comprises a corner frame 11, the corner frame 11 is fixed to the energy storage box by welding or screw connection, the lock seat 2 comprises an insert block 21, and stop ears 22 are fixed symmetrically on the side wall of the insert block 21 near the top, an insertion port 12 is opened at the top of the corner frame 11, the shape of the insert block 21 is adapted to the shape of the insertion port 12, one end of the insert block 21 passes through the insertion port 12 and is inserted into the interior of the corner frame 11, the stop ear 22 contacts the side wall of the corner frame 11, at this time, when the insert block 21 is inserted into the interior of the corner frame 11 through the insertion port 12, the side walls of the insert block 21 and the insertion port 12 are tightly fitted, so that the insert block 21 will not shake in the insertion port 12.

[0036] At the same time, a lock tongue 3 is provided on the lock seat 2, and a lock piece 4 is provided on the lower side of the lock tongue 3. The lock piece 4 and the lock tongue 3 are fixedly connected. When the lock tongue 3 rotates, the lock piece 4 is driven to rotate, and during the rotation of the lock piece 4, the lock piece 4 is clamped with the inside of the energy storage box corner piece 1. When the lock tongue 3 is pulled, the energy storage box is pulled up by the clamping connection between the lock piece 4 and the energy storage box corner piece 1. During the pulling of the lock piece 4, the lock seat 2 limits the position of the lock piece 4 to prevent the lock piece 4 from rotating inside the energy storage box corner piece 1, so as to prevent the device from being unhooked during use and improve the safety of the device.

[0037] Among them, the lock member 4 includes a lock plate 41, the shape of the lock plate 41 is the same as the shape of the plug block 21, and the middle position of the upper side of the lock plate 41 is recessed downward, and the bottom of the plug block 21 is provided with a bottom card slot 24 that fits with the upper side of the lock plate 41. When the plug block 21 and the lock plate 41 are aligned, the bottom card slot 24 and the upper side of the lock plate 41 fit tightly, the middle part of the lock plate 41 is recessed downward, and the bottom card slot 24 and the lock plate 41 fit tightly, that is, the middle part of the bottom card slot 24 protrudes downward, and the stability of the connection between the lock plate 41 and the plug block 21 is improved through the mutually staggered connection between the lock plate 41 and the bottom card slot 24.

[0038] At the same time, the lock tongue 3 includes a lock column 31 and a top pull ring 32 fixed to one end of the lock column 31. One end of the lock column 31 passes through the plug block 21 and the lock plate 41 and is sleeved with a retaining ring 33. The retaining ring 33 is fixed to the bottom of the lock plate 41 by a latch pin. The retaining ring 33 blocks the lock plate 41 from falling off the lock column 31. At the same time, a plurality of slots 34 are symmetrically provided on the side wall of the lock column 31 near the bottom. An insert strip 43 is fixed on the side wall of the lock plate 41 penetrated by the lock column 31. The insert strip 43 is slidably arranged in the slot 34. The lock plate 41 is locked by the plug-in cooperation between the slot 34 and the insert strip 43. The lock column 31 and the lock plate 41 are positioned between each other to prevent the lock plate 41 from rotating on the lock column 31, thereby improving the stability between the lock column 31 and the lock plate 41. A positioning hole 42 is provided on the side wall of the lock plate 41, and a screw 6 is threadedly connected in the positioning hole 42. One end of the screw 6 is threadedly connected to the lock column 31, and the lock column 31 and the lock plate 41 are further connected by the screw 6 to strengthen the stability of the connection between the lock column 31 and the lock plate 41. At the same time, the screw 6 is used to improve the tensile strength between the lock column 31 and the lock plate 41, so that when the lock tongue 3 pulls the lock element 4, the lock element 4 can withstand more weight.

[0039] After the lock plate 41 and the plug block 21 are inserted into the corner frame 11, the lock column 31 is rotated to rotate the lock plate 41 inside the corner frame 11, so that the plug block 21 and the lock plate 41 are arranged vertically. At this time, the lock column 31 is pulled to make the lock plate 41 contact with the side wall of the corner frame 11. The force of the lock column 31 pulling the lock plate 41 is transmitted to the corner frame 11 through the lock plate 41, so that the corner frame 11 pulls the energy storage box, thereby pulling the energy storage box up. At this time, in order to avoid the corner frame 11 and the lock plate 41 from being directly unhooked, a lock seat slot 23 is opened near the middle of the bottom of the plug block 21, and the lock plate 41 and the plug block 21 are connected. When 21 is set vertically, the lock plate 41 is set inside the lock seat slot 23, that is, the lock seat slot 23 positions the position of the lock plate 41, limits the rotation of the lock plate 41, and thereby avoids the situation where the lock plate 41 is separated from the side wall of the corner frame 11 due to the rotation of the lock plate 41 when the lock column 31 pulls the lock plate 41. At the same time, support plates 13 are fixed on both sides of the corner frame 11 near the insertion port 12. When the lock plate 41 and the plug block 21 are set vertically, one end of the lock plate 41 contacts the bottom of the support plate 13. The support plate 13 is used to improve the stability of the contact between the lock plate 41 and the corner frame 11, thereby further improving the positioning effect of the lock seat 2 on the lock plate 41.

[0040] In order to make the side walls between the lock plate 41 and the plug block 21 fit tightly, a spring baffle 35 is fixed to the position of the lock column 31 near the top pull ring 32, and a spring groove 25 is opened on the top of the plug block 21. A spring 5 is sleeved on the side of the lock column 31 near the spring baffle 35, and the other end of the spring 5 is arranged inside the spring groove 25. The spring 5 pushes the lock column 31 in the direction away from the lock member 4. At this time, the lock column 31 pulls the lock plate 41 to make the lock plate 41 and the side wall of the plug block 21 fit together. When the external force does not pull the lock column 31, the lock plate 41 and the plug block 21 can also be contacted by the thrust of the spring 5, thereby avoiding the situation where the lock plate 41 and the plug block 21 are separated and the position is offset when not in use, thereby improving the safety of the device.

[0041] By inserting the lock plate 41 and the plug block 21 into the interior of the corner frame 11 through the insertion port 12, and then rotating the lock plate 41, the lock plate 41 and the plug block 21 are arranged alternately, so that the lock plate 41 and the corner frame 11 are clamped together, and by pulling the lock tongue 3, the lock tongue 3 pulls the lock plate 41, and then the lock member 4 pulls the energy storage box corner member 1, and at the same time, the lock seat slot 23 receives the lock plate 41 to position the lock plate 41, so that the lock plate 41 will not rotate during use of the device, ensuring the stability of the connection between the lock member 4 and the energy storage box corner member 1, and preventing the lock member 4 and the energy storage box corner member 1 from detaching when the device is hoisting the energy storage box. At the same time, the overall structure of the device is simple and easy to manufacture, and it also reduces the difficulty of installation for workers.

[0042] The above shows and describes the basic principle, main features and advantages of the utility model.
