AI Technical Summary
The existing extremely narrow door-free floor spring lacks a buffer mechanism, which causes the door frame to collide when the door is closed, which makes it very noise and affects the service life. The complex structure leads to cumbersome installation and poor flexibility.
An extremely narrow door hole-free floor spring is designed, and a buffer mechanism is installed inside the shell. Through the joint use of the through cavity, cavity and bottom cavity, an internal spring is used to form a buffer mechanism to reduce the impact during closing of the door, and the shell is fixed by bolts without digging holes, simplifying the installation process.
It effectively reduces the impact on the door frame when closing the door, reduces noise, improves service life, and simplifies the installation process, improving the convenience and flexibility of installation.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of floor springs for extremely narrow doors, and specifically relates to a floor spring for extremely narrow doors that does not require digging pits. Background Technique
[0002] The floor spring for extremely narrow doors that does not require digging pits is a specially designed and manufactured floor spring product, which is characterized in that it can be directly installed and used on the ground without digging pits, and is suitable for occasions with limited space such as extremely narrow doors.
[0003] In the related technology, through retrieval, a solution for a quick-install adjustable floor spring fitting for extremely narrow profiles (publication number: CN217518464U) is found. When in use, by setting four first threaded grooves at different positions, the fitting main body can be more stably installed on the assembly profile, ensuring that different orientations of the fitting main body are fixed. Then, through the ground axis connection groove, the docking with the ground axis can be achieved, and the fine adjustment during the assembly process is more flexible and convenient with the holeless installation, and the overall strength and stability are guaranteed.
[0004] However, in the above-mentioned quick-install adjustable floor spring fitting for extremely narrow profiles, there is a lack of a buffer mechanism, resulting in the door colliding with the door frame when closing, and the noise is relatively large, making people feel noisy and affecting rest and sleep, thereby reducing the service life. And the existing floor spring for extremely narrow doors that does not require digging pits has a complex structure, resulting in cumbersome installation, poor flexibility, and very inconvenient installation, which is not conducive to promotion. In view of this, we introduce a floor spring for extremely narrow doors that does not require digging pits. Content of the Utility Model
[0005] The purpose of the utility model is to provide a floor spring for extremely narrow doors that does not require digging pits to solve the problems raised in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A floor spring for extremely narrow doors that does not require digging pits, comprising: a housing and a bottom hole;
[0007] A side hole is opened on the side of the housing, and the side hole and the housing are integrally formed. A fixing screw hole is opened below the side hole on the side of the housing, and the fixing screw hole and the housing are integrally formed;
[0008] The bottom hole is opened on the surface of the housing, and the bottom hole and the housing are integrally formed. A positioning hole is opened on the surface of the housing on one side of the bottom hole, and the positioning hole and the housing are integrally formed;
[0009] A buffer mechanism is arranged inside the housing. Through the combined use of the cavity and the through cavity of the buffer mechanism, the collision against the door frame when closing the door is reduced.
[0010] Preferably, the buffer mechanism includes a bottom cavity inside the housing. The bottom cavity and the housing are integrally formed. The cavity is opened inside the housing, and the cavity and the housing are integrally formed and located on one side of the side hole. The through cavity is opened inside the housing, and the through cavity and the housing are integrally formed and located at the bottom of the bottom hole. The bottom cavity is located at the bottom of the through cavity.
[0011] Preferably, a hydraulic hole is opened on the side of the housing, and the hydraulic hole and the housing are integrally formed.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: through the combined use of the through cavity, cavity and bottom cavity inside the housing, and by utilizing the springs inside the through cavity and cavity, a buffer mechanism is jointly formed, which solves the problem of impact on the door frame when closing the door, is quieter without noise, and improves the service life.
[0013] The bolts respectively pass through the fixing screw holes and the positioning holes, and the bolts are screwed into the interior of the object to fix the housing, eliminating the need for hole digging, so the installation is very simple, which is convenient for operation and popularization.
