A power connection unit is provided on the top of the power supply body 200. When the top cover 101 is covered at the top port position of the box-type housing 100, the power connection power source protrudes above the top cover 101. During the process of the top cover 101 covering the top port of the box-type housing 100, the top rod 102 is driven to be inserted into the guide cover 105, and the locking assembly in the guide cover 105 is cooperated to lock the position of the top rod 102, thereby realizing the locking and fixing of the top cover 101 at the top port position of the box-type housing 100, thereby completing the assembly of the power supply body 200 between the box-type housing 100.

[0034] It should be noted that a pressure plate 103 is provided under the top cover 101, and a spring 104 is fixedly connected between the pressure plate 103 and the top cover 101. The top cover 101 and the pressure plate 103 are both hollow.

Since a guide slot 106 is provided on the top inner side of the guide cover 105, and the bottom of the guide slot 106 is in the shape of a truncated cone that shrinks inward, it can squeeze one end of the insertion rod 110 during the downward movement of the driving rod 107, so that one end of the insertion rod 110 is automatically inserted into the slot 108 on the side wall of the top rod 102, so that the top rod 102 and the driving rod 107 can be pressed downward to achieve locking and fixation between the two, so that the top cover 101 cannot be pulled out reversely after it is installed in place.

[0035] The clamping mechanism includes four right-angle clamping blocks 303 arranged in a rectangular array at the top of the carrier plate 300, a positioning groove 301 matching the power source body 200 is opened in the middle of the top of the carrier plate 300, and a guide through hole 302 connected to the positioning groove 301 is opened at the corresponding position of the top of the carrier plate 300 and the right-angle clamping block 303. The driving mechanism includes a rotatable disc plate 304 movably connected to the bottom of the carrier plate 300, and a plurality of guide through holes 305 are spaced apart at the top of the disc plate 304. A guide connecting rod 306 is movably inserted into the inner side of the guide through hole 305. The top of the guide connecting rod 306 passes through the guide through hole 302 and is fixedly connected to the right-angle clamping block 303 at the corresponding position. The disc plate 304 and the carrier plate 300 are connected. A torsion spring is fixedly connected, and the torsion spring is used for rotational reset of the disc plate 304 after rotation. In the present embodiment, by rotating the disc plate 304, the guide through hole 305 on the disc plate 304 can be utilized to move and drive the guide connecting rod 306, and then the guide through hole 302 on the loading plate 300 acts as a limiting guide on the guide connecting rod 306, so that when the disc plate 304 rotates, the four right-angle clamps 303 can be synchronously driven to move toward each other, and the corners of the bottom of the outer wall of the positioned power supply body 200 are self-centering clamped. The configuration of the torsion spring enables the disc plate 304 to automatically rotate and reset after the force driving its rotation is withdrawn, thereby achieving the reverse movement unlocking operation of the right-angle clamps 303.

[0036] Furthermore, a traction rope 307 is fixedly connected to the side wall of the disc plate 304, a rotatable reel 308 is provided below the guide cover 105, and the reel 308 is used to reel in the traction rope 307. A fixed pulley 312 is provided between the reel 308 and the disc plate 304, and the fixed pulley 312 is rotatably connected to the bottom of the inner side of the box-type housing 100. A connecting tube 309 is rotatably connected to the bottom of the inner side of the guide cover 105. The bottom of the connecting tube 309 extends to the bottom of the guide cover 105 and is fixedly connected to the reel 308. A driving block 310 is fixedly connected to the top of the inner side of the connecting tube 309. The outer wall of the driving rod 107 is provided with a There is a spiral groove 311, and the end of the driving block 310 extends to the inner side of the spiral groove 311. When the driving rod 107 moves downward, the spiral groove 311 between the driving rod 107 and the connecting tube 309 and the limiting guiding effect between the driving block 310 can make the driving rod 107 move downward and drive the connecting tube 309 to rotate. In this way, the connecting tube 309 can use the downward movement of the top rod 102 to drive the winding wheel 308 to rotate and reel in the traction rope 307, thereby providing driving force for the rotation of the disc plate 304, so that the top cover 101 can be assembled and the power supply body 200 can be locked and positioned in the box-type housing 100 at the same time.

[0037] Furthermore, a hidden groove is provided at the bottom of the side wall of the box-type housing 100, and a cover plate 316 that can be rotatably opened and closed is movably connected to the side of the hidden groove. An auxiliary block 313 connected to the hidden groove is fixedly connected to the inner side of the box-type housing 100, and a cross rod 314 is movably inserted in the middle of the auxiliary block 313. A locking groove matching the cross rod 314 is provided on the side wall of the disc plate 304, and a spring three 315 is fixedly connected between the end of the cross rod 314 and the auxiliary block 313. When the disc plate 304 rotates to a position where the right-angle clamping block 303 clamps the power source body 200 stably, the locking groove on the disc plate 304 rotates to the position of one end of the cross rod 314, and the cross rod 314 is automatically inserted into the locking groove by the elastic force of the spring three 315, thereby limiting the rotation of the disc plate 304. In this way, the right-angle clamping block 303 can be ensured to be stably clamped. 03 The power source body 200 is clamped stably, and the connecting tube 309 cannot rotate, that is, the top rod 102 and the driving rod 107 cannot be moved up to unlock, thereby ensuring the stability of the assembly between the box-type housing 100, the top cover 101 and the power source body 200, eliminating the use of fasteners, and simplifying the assembly steps. Manual operation only needs to press the top cover 101 to complete the assembly. The operation is convenient and efficient. At the same time, it also has a certain anti-theft effect. An electronic lock or a mechanical lock can be installed between the cover plate 316 and the box-type housing 100 to increase the anti-theft effect. When unlocking, you only need to open the cover plate 316 and manually pull out the cross rod 314, so that the disc plate 304 can rotate through the torsion spring, and the top cover 101 can be taken out upwards. In this way, the assembly or disassembly between the power source body 200 and the box-type housing 100 is more convenient and efficient.

[0038] Embodiment 2: The present invention also provides a method for using a power supply device, comprising the following steps:

[0039] Step 1: Place the power source body 200 into the inner cavity of the box-type housing 100 and insert the bottom of the power source body 200 into the positioning groove 301 at the top of the loading plate 300, then cover the top cover 101 at the top port of the box-type housing 100, and insert the top rod 102 into the inner side of the guide cover 105 at the corresponding position;

[0040] Step 2: The bottom end of the push rod 102 and the top end of the driving rod 107 squeeze the driving rod 107 downward, and the top of the driving rod 107 moves downward from the guide slot 106. When the top of the driving rod 107 drops to the bottom position of the guide slot 106, since the inner side of the bottom of the guide slot 106 is inclined, it squeezes and guides the insertion rod 110 at the top position of the driving rod 107, so that one end of the insertion rod 110 moves horizontally and is inserted into the slot 108 on the side wall of the push rod 102, thereby achieving locking between the push rod 102 and the driving rod 107.

[0041] Step 3: When the driving rod 107 is squeezed and moved downward by the push rod 102, the limit guide cooperation between the spiral groove 311 and the driving block 310 is used to make the driving rod 107 move downward and drive the connecting tube 309 to rotate. The connecting tube 309 drives the winding wheel 308 to rotate, and the traction rope 307 is wound up, so that the traction rope 307 drives the disc plate 304 to rotate. When the disc plate 304 rotates, the guide through hole 305 and the guide through hole 302 respectively guide the guide through hole 305, so that the disc plate 304 can rotate and drive the four right-angle clamps 303 to move synchronously along the corresponding guide through hole 302 trajectory, so as to clamp the four corners of the bottom of the outer wall of the power supply body 200;

[0042] When the locking cam 314 is in the state of being moved upward, the top cover 101 is lifted off the top of the box-type housing 100 and the top cover 101 is lifted off the top of the box-type housing 100. When the locking cam 314 is in the state of being moved upward, the top cover 101 is lifted off the top of the box-type housing 100 and the top cover 101 is lifted off the top of the box-type housing 100.

A locking groove that matches the cross rod (314) is provided on the side wall of the disc plate (304), and a spring three (315) is fixedly connected between the end of the cross rod (314) and the auxiliary block (313).

10. The method for using a power supply device according to claim 9, characterized in that: The following steps are involved: Step 1: Place the power source body (200) into the inner cavity of the box-type housing (100) and insert the bottom of the power source body (200) into the positioning groove (301) at the top of the loading plate (300), then cover the top cover (101) at the top port position of the box-type housing (100), and insert the top rod (102) into the inner side of the guide cover (105) at the corresponding position; Step 2: The bottom end of the push rod (102) and the top end of the driving rod (107) squeeze the driving rod (107) downward, and the top of the driving rod (107) moves downward from the guide slot (106). When the top of the driving rod (107) drops to the bottom position of the guide slot (106), since the inner side of the bottom of the guide slot (106) is in the shape of an inclined surface, it plays a squeezing and guiding role on the insertion rod (110) at the top position of the driving rod (107), so that one end of the insertion rod (110) moves horizontally and is inserted into the slot (108) on the side wall of the push rod (102), thereby achieving locking between the push rod (102) and the driving rod (107); Step 3: When the driving rod (107) is pressed and moved downward by the push rod (102), the limiting guide cooperation between the spiral groove (311) and the driving block (310) is used to make the driving rod (107) move downward and drive the connecting tube (309) to rotate. The connecting tube (309) drives the winding wheel (308) to rotate, and the traction rope (307) is wound up, so that the traction rope (307) drives the circular plate (304) to rotate. When the circular plate (304) rotates, the guiding through hole (305) and the guiding through hole (302) respectively guide the guiding through hole (305), so that the circular plate (304) can drive the four right-angle clamping blocks (303) to move synchronously along the corresponding guide through hole (302) trajectory, thereby clamping the four corners of the bottom of the outer wall of the power source body (200); Step 4: When the right-angle clamp (303) achieves stable clamping of the power source body (200), the locking groove of the side wall of the disc plate (304) moves to the position of the cross rod (314), and the cross rod (314) cooperates with the elastic thrust of the spring three (315) to automatically insert into the locking groove of the side wall of the disc plate (304), thereby limiting the rotation of the disc plate (304). At this time, the top cover (101) cooperates with the pressure plate (103) and the spring one (104) to play a stable pressing role on the top of the power source body (200), thereby completing the power source body (2 00) is assembled in the box-type housing (100). When unlocking, the cover plate (316) is opened, and the cross rod (314) is manually pulled outward to release the restriction on the rotation of the disc plate (304). At this time, the top cover (101) can be pulled upward, and the disc plate (304) rotates through the torsion spring. The top rod (102) and the driving rod (107) rise to the guide groove (106) to gradually achieve unlocking, so that the top cover (101) can be removed from the box-type housing (100), and the power supply body (200) can be directly taken out to complete the disassembly work.
