Description

Technical Field

[0001] The utility model relates to the technical field of charging pile installation, in particular to a fixing device for charging pile installation. Background Art

[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. During the installation of the charging pile, a fixing device is required to fix the charging pile.

[0003] For example, Chinese patent announcement No. CN219989025U discloses a fixing device for installing a charging pile. When in use, the installer first uses external expansion bolts to fix the positioning plate to the specified position of the external cement floor, thereby installing and fixing the supporting base plate, and then the charging pile body can be placed vertically in the rectangular groove. At this time, the clamping seats on the left and right sides can be pushed inward. When the clamping seats are moved into place, the first fixing groove will be clamped with the first extension block, and the second fixing groove will be clamped with the second extension block, thereby stabilizing the charging pile body. Fixed; then the installer can insert the positioning pin from top to bottom and install it in the positioning groove to position the clamping seat to prevent the clamping seat from being displaced left and right again. At the same time, the T-shaped limit slide rail also prevents the clamping seat from being displaced up and down, thereby further improving the fixing stability of the clamping seat to the charging pile body; then the installer uses the fixing screws to install the protective cover at the specified position on the upper end surface of the clamping seat, so that the protective cover can block and protect the positioning pin, and the fixing screws are anti-theft screws to prevent strangers from easily dismantling the protective cover, which can make the clamping seat easy to be taken away.

[0004] However, the fixing device for installing the charging pile in the above application can only fix and install the charging pile that is specifically equipped with an extension block. It cannot fix the charging piles of different sizes and shapes well, so there are certain limitations.

[0005] For this reason, we urgently need to provide a fixing device for installing a charging pile. Utility Model Content

[0006] The purpose of the utility model is to provide a fixing device for installing a charging pile, so as to solve the problem that the fixing device for installing a charging pile proposed in the above-mentioned background technology can only fix and install a specific charging pile equipped with an extension block, and cannot fix the charging piles of different sizes and shapes well.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a fixing device for installing a charging pile, comprising a base and a charging pile, wherein the charging pile is installed at the center of the upper surface of the base, and a fixing device is provided on the upper surface of the base.

[0008] The fixing device comprises a fixing unit, a stretching unit and a locking unit.

[0009] The fixing unit includes guide rails, fixing blocks, and fixing bolts. The two guide rails are respectively fixedly connected to the front and rear ends of the upper surface of the base, the two fixing blocks are respectively slidably connected to the guide rails, and the two groups of fixing bolts are respectively threadedly connected to the front and rear ends of the upper surfaces of the two fixing blocks.

[0010] A further improvement is that guide rail grooves are respectively opened on the front and rear sides of the fixing block, threaded holes are respectively opened through the front and rear ends of the upper surface of the fixing block, and locking slots are respectively opened on the upper surface of the guide rails. When facing charging piles of different sizes, the fixing block is pulled outward to slide outward along the guide rail until its inner wall is engaged with the outer wall of the charging pile, and then the fixing bolt is screwed into the bolt hole on the fixing block until the fixing bolt is screwed into the locking slot, thereby completing the fixed installation of the charging pile. It can adapt to charging piles of different sizes, thereby improving the scope of application of the device.

[0011] A further improvement is that the stretching unit includes a spring bin, a stretching spring, and a sliding block, the spring bin is opened on the left side of the upper surface of the base, the stretching spring is installed inside the spring bin, the sliding block is fixedly connected to the outer end of the stretching spring, and its top is fixedly connected to the bottom of the fixed block.

[0012] A further improvement is that there are two groups of stretching units, which are symmetrically arranged on the left and right sides of the upper surface of the base. The left and right sides of the upper surface of the base are respectively provided with movable grooves, and the sliding block is slidably connected to the inside of the movable groove. When the fixed block moves outward, the sliding block is pulled to move outward along the movable groove and the stretching spring is pulled until the fixed block moves to the outside of the charging pile. After the fixed block is released, the stretching spring is reset under the action of its own elasticity, thereby pulling the fixed block close to the charging pile, thereby improving the stability of the charging pile.

[0013] A further improvement is that the locking unit includes a threaded rod, a locking nut, a bearing, and an abutment plate, the threaded rod is rotatably connected to the front end of the fixed block, the locking nut is threadedly connected to the threaded rod, the bearing is installed at the tail of the threaded rod, and the abutment plate is fixedly connected to the rear end of the bearing.

[0014] A further improvement is that a threaded hole corresponding to the threaded rod is opened on the front side of the fixing block, and the threaded rod is threadedly connected to the inside of the threaded hole. The threaded rod is turned to rotate backward along the threaded hole, thereby pushing the abutment plate to move backward until it is close to the charging pile, and then the locking nut is tightened to fix the threaded rod, thereby better clamping and fixing the charging pile.

[0015] A further improvement is that positioning ear plates are fixedly connected to the left and right sides of the front and rear ends of the upper surface of the base, and the base is fixed in the installation position by expansion screws and the positioning ear plates. Anti-slip rubber pads are adhered to the inner wall of the fixed block and the outer side of the abutment plate, respectively. The provision of the anti-slip rubber pads enhances the friction with the charging pile and further improves the fixing effect of the charging pile.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. When facing charging piles of different sizes, the fixing block is pulled outward to slide outward along the guide rail until its inner wall is engaged with the outer wall of the charging pile, and then the fixing bolt is screwed into the bolt hole on the fixing block until the fixing bolt is screwed into the locking slot, thereby completing the fixed installation of the charging pile. The device can adapt to charging piles of different sizes, thereby improving the application range of the device.

[0018] 2. The fixing device for installing the charging pile, when the fixing block moves outward, pulls the sliding block to move outward along the moving groove and pulls the tension spring until the fixing block moves to the outside of the charging pile. After releasing the fixing block, the tension spring resets under the action of its own elasticity, thereby pulling the fixing block close to the charging pile, thereby improving the stability of the charging pile.

[0019] 3. The fixing device for installing the charging pile is to screw the threaded rod to rotate it backward along the threaded hole, thereby pushing the abutment plate to move backward until it is close to the charging pile, and then tighten the locking nut to fix the threaded rod to better clamp and fix the charging pile.
