Description

Technical Field

[0001] The utility model relates to the technical field of door closers, in particular to a floor spring base structure without opening holes. Background Art

[0002] A floor spring is a common door closer. Compared with a common door closer that can only be opened unidirectionally, a floor spring can be used for bidirectional opening of a door. After retrieval, a patent with the Chinese patent publication number CN210033060U discloses a floor spring structure without digging. Although this floor spring fixes the housing at the bottom of a glass door, thus eliminating the need for digging, it is convenient for installation. At the same time, subsequent maintenance and replacement do not require digging the ground, which is convenient for maintenance and improves work efficiency, solving the problem of the troublesome excavation required for the installation of traditional floor springs. However, the floor spring base cannot be adjusted horizontally after being fixed, which leads to a high requirement for the installation accuracy when installing the base. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a floor spring base structure without opening holes, solving the problem that the existing floor spring in the background art cannot be adjusted horizontally after installation, which leads to a high requirement for the installation accuracy of the base when installing, thus increasing the installation difficulty.

[0004] To achieve the above object, the utility model is realized through the following technical solutions: A floor spring base structure without opening holes, including a floor spring body, a first bottom plate, a second bottom plate, a first adjusting screw, and a first adjusting hole. An installation groove is opened at the top of the floor spring body, and the installation groove is used to fix a glass door. The bottom of the floor spring body is inserted into the inner hole of a positioning groove, and the positioning groove is embedded in a second positioning hole. The second positioning hole is opened on the surface of the first bottom plate. Four first adjusting holes are opened at the four ends of the surface of the first bottom plate. A first adjusting screw is arranged inside the first adjusting hole. One end of the bottom of the first adjusting screw is threadedly connected to a first positioning hole. The first positioning hole is opened on the surface of the second bottom plate. Expansion screw holes are opened at both ends of the second bottom plate, and the expansion screw holes are used to fix expansion screws to install the second bottom plate.

[0005] Preferably, the inner diameter of the first adjusting hole is larger than that of the first positioning hole, and there is a gap between the inner wall of the first adjusting hole and the first adjusting screw, which is beneficial for the first bottom plate to adjust its position outside the first screw. The gap between the first adjusting hole and the first adjusting screw is the moving stroke of the first bottom plate.

[0006] Preferably, a gasket is sleeved outside the first adjusting screw. The gasket is made of stainless steel, and the diameter of the gasket is larger than the inner diameter of the first adjusting hole. The bottom surface of the gasket is in sliding contact with the top surface of the first bottom plate. By tightening the first adjusting screw, the first adjusting screw can drive the gasket to press down and compress the first bottom plate, so that the position of the first bottom plate can be fixed.

[0007] Preferably, four fourth positioning holes are formed on the surface of the first bottom plate. The inside of the fourth positioning hole is threadedly connected with a third adjusting screw, and the bottom of the third adjusting screw is closely attached to the surface of the second bottom plate. By loosening the first adjusting screw and then rotating the third adjusting screw, the third adjusting screw can move downward inside the fourth positioning hole, so that the gap between the first bottom plate and the second bottom plate can be adjusted under the action of the third adjusting screw, which is beneficial to adjusting the height of the first bottom plate.

[0008] Preferably, a third positioning hole is formed at one end of the second bottom plate. The inside of the third positioning hole is threadedly connected with a second adjusting screw. By rotating the second adjusting screw, the bottom of the second adjusting screw can abut against the ground, so that the installation height at both ends of the second bottom plate can be adjusted.

[0009] Preferably, a second adjusting hole is formed in the middle of the surface of the second bottom plate, and the second adjusting hole is larger than the second positioning hole, which is beneficial to enabling the bottom of the positioning groove to move inside the second adjusting hole when the first bottom plate moves.

[0010] The utility model provides a floor spring base structure without opening holes, which has the following beneficial effects:

[0011] (1). For this floor spring base structure without opening holes, when the floor spring is in use, the second bottom plate is fixed by inserting expansion screws into the expansion screw holes, and then the bottom of the floor spring is inserted into the positioning groove. By loosening the first adjusting screw, the first bottom plate and the positioning groove can be adjusted horizontally in any direction, which is beneficial to adjusting the position of the floor spring after the second bottom plate is fixed, thus reducing the installation difficulty of the floor spring. Then, by tightening the first adjusting screw, the first adjusting screw can move downward, and then drive the gasket to move downward, so that the gasket can compress the first bottom plate and fix the position of the first bottom plate.

[0012] (2). For this floor spring base structure without opening holes, by loosening the first adjusting screw and then rotating the third adjusting screw, the third adjusting screw can move downward inside the fourth positioning hole, so that the gap between the first bottom plate and the second bottom plate can be adjusted under the action of the third adjusting screw, which is beneficial to adjusting the height of the first bottom plate and improving the adjustability of the floor spring.

[0013] Thus, the problem that the existing floor springs cannot be adjusted horizontally after installation, resulting in high precision requirements for the base during installation and thus increasing the installation difficulty, is solved. BRIEF DESCRIPTION OF THE DRAWINGS
