It can not only close the door automatically, but also combines multiple door closing functions such as buffering, positioning, and speed regulation, which can meet the usage requirements in more scenarios. It automatically closes after the door body is opened by the force of hydraulic pressure or a spring, and realizes functions such as buffering and positioning during this process.
[0003] When installing the closer of the steel art door, it is necessary to drill holes and fix it on the door body. The steel art door is a relatively thick multi-layer door panel, and drilling and installing are likely to affect the original sound insulation and other effects of the door body. When the closer is disassembled, it will cause irreversible damage to the door body. Content of the Utility Model
[0004] In order to solve the problems of the above technology, the purpose and efficacy of a multi-functional closer for a steel art door of the utility model are achieved by the following specific technical means:
[0005] Its structure includes a fixed foot, a support rod, a connecting rod, a limit ring, an adjusting thread, a hydraulic buffer group, and a fixed seat. The limit ring is sleeved on the outer surface of the adjusting thread. The adjusting thread is installed between the support rod and the fixed foot. The support rod is connected to the hydraulic buffer group through the connecting rod. The fixed seat is fixed on the lower surface of the hydraulic buffer group;
[0006] The adjusting thread can be telescopically moved along the support rod to adjust the length. The limit ring fixes the distance adjusted by the adjusting thread. The support rod adjusts the required angle by swinging with the connecting rod. The fixed seat assists the hydraulic buffer group to be fixed on the surface of the door body. The fixed foot is fixed on the surface of the door frame. The fixed foot is in a large triangle structure and can be connected more stably.
[0007] As a further improvement of the utility model, the fixed seat includes a fixed strip, a connecting seat, and a colloid. The colloid is embedded at the bottom of the connecting seat for fitting. The fixed strip is embedded on the left and right sides of the connecting seat. The fixed strip is pulled according to the distance between the two sides of the door frame and clamped on the edge of the door frame. The colloid is a reusable sticky colloid structure, which assists the whole to better adhere to the surface of the door body.
[0008] As a further improvement of the utility model, the hydraulic buffer group includes a hydraulic end, a regulating valve, a connecting shaft, and a wrapping shell. The hydraulic end is installed inside the wrapping shell. The regulating valve is installed on the outer surface of the wrapping shell. The connecting shaft is fixed on the surface of the wrapping shell. There are two regulating valves, and the surface is provided with protruding parts to enable better force application and rotation.
[0009] As a further improvement of the present utility model, the hydraulic end includes a piston and a spring. The piston is connected to the spring. The connecting shaft cooperates with the piston and the spring through a gear shaft. The regulating valve rotates to control and adjust the closing speed inside the wrapping shell. The connecting shaft is embedded inside the wrapping shell through the gear shaft.
[0010] As a further improvement of the present utility model, the fixing strip includes a hook plate, a pulling strip, and a collar. The hook plate is fixed to the end of the collar. The collar is sleeved on the outer surface of the pulling strip and evenly distributed. The hook plate is in an L-shaped structure and can be better fixed to the edge of the door body. The pulling strip is made of rubber material and can be better pulled.
[0011] As a further improvement of the present utility model, the collar divides the pulling strip into multiple sections, so that the force will not be too concentrated. The head end of the collar is embedded inside the connecting seat for fixation. The outer surface of the colloid is a flat soft structure and can better fit and adhere.
[0012] Compared with the prior art, the present utility model has the following beneficial effects:
[0013] 1. After the fixing feet are installed, the colloid of the fixing seat is placed on the door body surface for adsorption. By applying an external force to pull the hook plate, the pulling strip follows the movement of the hook plate for stretching. When stretched to the edge of the door frame, the hook plate is buckled on the edge of the door frame. The collar divides the pulling strip into multiple segments, so that the force can be dispersed. Without drilling holes in the door body, the colloid can adsorb the door body, and by pulling the pulling strip, the hook plate is buckled on the edge of the door frame for auxiliary fixation, so that the hydraulic buffer group can be stably installed on the door body surface.
[0014] 2. Originally, the adjustment knob for adjusting the closing speed of the door body needs to be rotated and adjusted by screws. By expanding the force application range of the regulating valve, the operator can easily rotate the regulating valve by an external force to adjust the closing speed of the door body.
