Description

Technical Field

[0001] This utility model relates to a novel cabinet door opener / closer, specifically a cabinet door opener / closer that has a strong clamping force when closing, a rapid response when opening, and a large elasticity. Background Technology

[0002] Most cabinet door openers on the market currently use magnetic or claw suction in their physical structure. Magnetic suction is less adaptable to different cabinet door usage scenarios because the magnetic force cannot be adjusted. Traditional claw suction structures need improvement in terms of ease of adjustment, gripping force, and smoothness of opening response. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of cabinet door opener / closer. It uses a physical structure in which the spring core extends and retracts within the inner shell to release or tighten the latch on the fixed hook seat. This achieves a simple structure and greatly improves the biting force and the smoothness of the door opening response.

[0004] The technical solution of this utility model is based on the outer shell, adjusting nut, fixed hook seat, adjusting base, hook needle, spring, spring core, latch claw, and inner shell. Its feature is that the inner shell can be inserted into the outer shell through the front opening of the outer shell for installation, and the adjusting base is inserted into the rear end of the inner shell for fixed installation. A limit plate is provided in the middle of the adjusting base to limit the adjustment distance of the adjusting base. A screw protrudes outward from the middle of the rear of the limit plate, and the adjusting nut is threaded onto the screw. A detachable locking platform is provided in front of the limit plate for upper and lower coupling and fixing one end of the hook needle. An adjustment mechanism is provided at the top of the outer shell relative to the adjusting nut. The window has an adjusting nut that protrudes outwards at the top. The spring core is inserted into the front end of the inner shell and can move forward and backward. The latch can open or close and is installed at the front end of the spring core. The tail end of the spring core is an upper semi-circular extension, and the front end of the adjusting seat is a lower semi-circular extension. The tail end of the spring core and the upper and lower semi-circular extensions of the front end of the adjusting seat are staggered and intersected. The spring is sleeved on the intersection of the spring core and the adjusting seat. The bottom of the upper semi-circular extension of the tail end of the spring core is provided with a spring guide groove. The top surface of the lower semi-circular extension of the front end of the adjusting seat is provided with a hook. The front end of the hook bends upward and extends into the spring guide groove of the spring core, and can slide back and forth along the spring guide groove.

[0005] The fixed hook base described in this utility model is an inverted triangle with a cylinder at the tail end. When the fixed hook base collides with the spring core from front to back, it can cause the spring core to move backward and retract into the inner shell. At this time, the latches close and hold the cylinder of the fixed hook base tightly. When the latches hold the cylinder of the fixed hook base tightly, the fixed hook base can also move up and down to be configured for installation in appropriate upper and lower positions.

[0006] The inner shell of this utility model has an adjustment scale at the top front end, and a positioning ring is provided at the bottom front end of the outer shell. The bottom front end of the positioning ring has a positioning rib protruding downwards, which is used to position the outer shell when the opener / closer is installed.

[0007] The working principle of this utility model is as follows: when the cabinet door is open, the spring core extends and the latch opens; when the cabinet door is closed, the cylinder of the fixed hook base pushes into the latch, is compressed by external force, the spring core contracts, the latch closes, and bites the cylinder. At this time, the hook slides into the spring guide groove to restrict the spring core to pop forward. When the spring core is compressed again by external force, the hook slides out of the spring guide groove to restrict the spring core to pop forward. At this time, the spring returns to its original position, causing the spring core to extend forward out of the inner shell. At this time, the latch releases the cylinder of the fixed hook base under the pulling force, thereby separating the fixed hook base from the spring core. This cycle realizes the opening and closing action. When the latch closes, because the latch retracts into the inner shell, it restricts its opening, so the biting force is equal to the hardness of the inner shell. When the spring core rebounds, the latch extends out of the inner shell and loses the opening restriction. It is naturally opened by the pulling force of the fixed hook base. The process is smooth and does not require a complex structure, making the product work more stably.

[0008] The advantages of this utility model are that it is more stable, most of the parts are integrally formed, it is not easy to deform, it is ingeniously designed, it makes full use of mechanical principles, it has a strong clamping force when closing the door, a fast response when opening the door, great elasticity, long service life, low cost, and is more convenient to install and disassemble.

[0014] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this utility model, based on the outer shell 1, adjusting nut 2, fixed hook seat 3, adjusting seat 4, hook 4.1, spring 5, spring core 6, latch 6.1, and inner shell 7, features an inner shell 7 that can be inserted into the outer shell 1 from the front opening and installed back and forth. The adjusting seat 4 is inserted into the rear end of the inner shell 7 for fixed installation. A limiting plate 4.3 is provided in the middle of the adjusting seat 4 to limit the adjustment distance of the adjusting seat 4. A screw protrudes outward from the middle of the rear of the limiting plate 4.3. The adjusting nut 2 is threaded onto the screw. A detachable locking platform 4.2 is provided in front of the limiting plate 4.3 for upper and lower coupling and fixing one end of the hook 4.1. The top of the outer shell 1 is positioned relative to the adjusting nut 2. An adjustment window is provided, with the top of the adjustment nut 2 protruding outward from the window. The spring core 6 is inserted into the front end of the inner shell 7 and can move forward and backward. The latch 6.1 can be opened or closed and is installed at the front end of the spring core 6. The tail end of the spring core 6 is an upper semi-circular extension section, and the front end of the adjustment seat 4 is a lower semi-circular extension section.
