[0030] Specifically, the upper shell 2 can be easily and accurately placed on the lower shell 1 through the suction effect of the magnet 6 and the large flat head screw column 9, greatly simplifying the installation process.

[0036] ​​Specific, by the cooperation of wedge 125 and second spring 124, locking mechanism 12 can provide stable locking force, when the positioning block 126 is in contact with wedge 125 and pushes it into the second cavity 122, the resilience of the second spring 124 tightly presses the wedge 125 in the inner cavity of the positioning block 126, thereby ensuring the connection between the upper shell 2 and the lower shell 1 is tight and stable.

[0037] The inner cavity of the second cavity 122 is provided with a sliding groove 13 on both sides, as shown in Figures 1-9

[0038] The inner cavity of the sliding groove 13 is slidably connected with a sliding block 14, one side of the sliding block 14 is fixedly connected with a circular block 123, one side of the inner cavity of the first cavity 10 is provided with a T-shaped groove 15, the inner cavity of the T-shaped groove 15 is slidably connected with a T-shaped block 16, one side of the T-shaped block 16 is fixedly connected with a moving block 112, the bottom of the upper shell 2 is fixedly connected with a supporting block 17, the number of the supporting block 17 is several, both sides of the top of the lower shell 1 are provided with inclined surfaces, and the surfaces of the inclined surfaces are smooth, the second spring 124 and the circular block 123 form an extension structure, and the maximum moving distance of the circular block 123 is equal to the deformation amount of the second spring 124.

[0039] Specifically, the cooperation of the sliding groove 13 and the sliding block 14 plays a limiting role for the circular block 123, improves the stability of the circular block 123 during movement, the cooperation of the T-shaped groove 15 and the T-shaped block 16 plays a supporting role for the moving block 112, prevents the moving block 112 from deviating during movement, the supporting block 17 is arranged to fix the upper shell 2, so that the upper shell 2 is not easy to deform, and the resilience of the second spring 124 can firmly place the wedge 125 in the inner cavity of the positioning block 126, thereby improving the stability of the connection between the lower shell 1 and the upper shell 2.

[0040] The working principle of the magnet adsorption quick mounting structure for the charging pile is as follows:

[0041] When the device is in use, the user places the magnet 6 in the inner cavity of the first positioning column 3, and then penetrates one end of the countersunk screw 5 into the inner cavity of the threaded hole 4, rotates the countersunk screw 5, and the magnet 6 can be locked and fixed.

[0042] Further, the flat head screw column 9 is placed in the inner cavity of the second positioning column 7, and then the flat head screw column 9 is rotated to gradually move downward in the inner cavity of the second positioning column 7, and when the bottom of the flat head screw column 9 is in contact with the second positioning column 7, the cross head screw 8 can be used to lock and fix the flat head screw column 9. ​

[0043] Further, the upper shell 2 is moved downwardly and placed on the top of the lower shell 1, so that the magnet 6 is in contact with the large flat screw column 9, and the attractive force generated by the magnet 6 can make them in close contact.

[0044] Further, the positioning block 126 is moved downwardly when the upper shell 2 is moved, and when the positioning block 126 is in contact with the wedge-shaped block 125, the positioning block 126 can drive the wedge-shaped block 125 to move into the inner cavity of the second cavity 122 through the downward pressure of the positioning block 126 and the inclined surface of the wedge-shaped block 125, the wedge-shaped block 125 drives the round block 123 to move, and the round block 123 drives the second spring 124 to compress.

[0045] Further, when the wedge-shaped block 125 completely enters the inner cavity of the second cavity 122, the bottom of the positioning block 126 is in contact with the lower shell 1, and the wedge-shaped block 125 enters the inner cavity of the positioning block 126 through the rebound force of the second spring 124, so that the tightness of the connection between the lower shell 1 and the upper shell 2 can be increased.

[0046] For example, when the cross-head screw 8 and the large flat screw column 9 are rotated for many times and the threads of the cross-head screw 8 are worn, the cross-head screw 8 is moved upwardly, the adjusting block 111 is driven to make arc motion with one side as the center, the adjusting block 111 drives the guide block 113 to slide in the inner cavity of the moving block 112.

[0047] Further, the moving block 112 is moved downwardly, and the first spring 114 is compressed when the moving block 112 is moved, and the adjusting block 111 gradually separates from the inner cavity of the limiting slot 115 when making arc motion, so as to enter the inner cavity of the first cavity 10, and the cross-head screw 8 can be taken out from the inner cavity of the second positioning column 7 when the adjusting block 111 completely enters the inner cavity of the first cavity 10, so as to facilitate the user to replace it.

[0048] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced equivalently, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
