Therefore, it is necessary to improve it. Summary of the invention

[0004] The purpose of the utility model is to provide an integrated DC charging pile assembled in a modular manner, which solves the problem that the lifting ring at the bottom of the existing integrated DC charging pile assembled in a modular manner is relatively fixed, making it inconvenient to lift the charging pile. At the same time, it solves the problem that the charging pile requires multiple sets of bolts for installation and fixation, making it inconvenient to disassemble and repair it later.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an integrated DC charging pile with modular assembly, including a base and a charging column body, the bottom of the charging column body is fixedly connected with a mounting bar, the mounting bar is slidably connected to the base, a bidirectional screw is installed inside the base through a bearing, the threaded portion of the bidirectional screw is threadedly connected to a moving block, the moving block is slidably connected to the inner side of the base, the moving block contacts the mounting bar, and a clamping block is fixedly connected to the side of the moving block close to the mounting bar, and the clamping block is clamped with the mounting bar.

[0006] The principle of the utility model is that when in use, the base is first fixed in a predetermined position, and then the rotating disk is rotated by the knob to make the telescopic pin at the end of the sliding pin telescope, thereby controlling the spacing of the lifting rings to facilitate the lifting of the lifting rings, and then the charging pile body is placed on the base through the tool, and the mounting bar at the bottom of the charging pile body is inserted into the base, and then the bidirectional screw is rotated by the knob, and the moving block moves horizontally through the relative thread movement with the bidirectional screw, and then the moving block is attached to the side of the mounting bar, and the card block on the moving block is inserted into the mounting bar, thus completing the installation of the charging pile body, and the same reverse knob can be used to disassemble the charging pile body, which is convenient for later factory inspection and maintenance.

[0007] The beneficial effect of the utility model is that: a fixed plate is arranged on the top of the charging pile body, a telescopic pin that can be telescopically slid is arranged in the fixed plate, and a lifting ring is provided on the telescopic pin, so that when the rotating plate rotates, the circular arc groove on the rotating plate enables the telescopic pin to be telescoped, thereby controlling the spacing of the lifting rings and facilitating the lifting of the lifting rings;

[0008] By setting two mounting bars at the bottom of the charging pile body, the mounting bars can be inserted into the base, and then two moving blocks whose positions are controlled by bidirectional screws are set in the base, and the card block on each moving block will be inserted into the mounting bar laterally. In this way, the disassembly and assembly of the charging pile body can be completed by simply controlling the clutch between the card block and the mounting bar, which is convenient for later factory inspection and maintenance.

A fixed shaft is installed at the middle part of the upper end of the fixed plate through a bearing, and a rotating plate is fixedly connected to the top of the fixed shaft, and the sliding pin passes through the rotating plate and is slidably connected to the rotating plate. The telescopic pin at the end of the sliding pin is extended and retracted by rotating the rotating plate, thereby controlling the spacing of the lifting rings and facilitating the lifting of the lifting rings.

[0010] Furthermore, a shock absorbing pad is fixedly connected to the middle part of the lower end of the charging pile body, and the shock absorbing pad is in contact with the base. The setting of the shock absorbing pad has a certain supporting effect on the charging pile body.

[0011] Furthermore, a ball bearing is arranged at the bottom of the moving block, and the ball bearing is slidably connected to the inner surface of the base. By arranging the ball bearing, the relative friction between the moving block and the base can be reduced.

[0012] Furthermore, one end of the bidirectional screw rod located outside the base is fixedly connected with a knob, and the knob is made of stainless steel. The setting of the knob makes it easy to rotate the bidirectional screw rod.

[0013] Furthermore, a circular arc groove is provided inside the rotating disk, and the upper end of the sliding pin is located in the circular arc groove. By providing the circular arc groove, the sliding pin can be subjected to radial force of the rotating disk.

[0014] Furthermore, a knob is fixedly connected to the middle of the upper end of the rotating disk, and the knob is made of stainless steel. The setting of the knob makes it easy to rotate the rotating disk. BRIEF DESCRIPTION OF THE DRAWINGS
