Description

Technical Field

[0001] The utility model relates to a novel cabinet door closer, in particular to a double-buffered low-noise door closer. Background Art

[0002] Door closers are common components in door locking installations. However, the tail ends of the door closer swing arms currently on the market all use connecting springs, and are designed with a single spring, which results in low elasticity and unstable buffering of the door closers. Utility Model Content

[0003] The purpose of the utility model is to provide a novel cabinet door closer, which provides sufficient buffering force for the door closer by adopting left and right hydraulic buffers through a buffer seat, effectively solving the problem of insufficient buffering force of the door closer, and at the same time adds buffering anti-collision rubber at the relative position of the tail end of the swing arm, so that the noise of the door closer is smaller when it is working.

[0004] The technical solution of the utility model is that the shell, swing arm, touch switch, touch spring, slider, locking slide rod, reset spring, buffer seat, hydraulic buffer, buffer spring, buffer anti-collision rubber, pulley, and slider are installed in the middle of the top of the shell, and the characteristic is that the tail end of the swing arm is hingedly installed on the right end of the shell, and the buffer anti-collision rubber is fixed to the right side of the tail end of the swing arm in the shell; the buffer seat can be slid left and right by the slide rod to be installed in the shell below the slider, and the left and right ends of the buffer seat are respectively installed with hydraulic buffers, and the slide rod protruding out of the right end of the buffer seat is covered with a buffer spring.

[0005] The tail end of the swing arm described in the utility model can contact the buffer head at the right end of the buffer seat when it swings clockwise, and cause the buffer seat to slide leftward. The hydraulic rods of the left and right hydraulic buffers in the buffer seat protrude toward the left and right ends of the buffer seat respectively and contact the inside of the shell, providing buffering force for the buffer seat when the buffer seat slides; when the tail end of the swing arm swings counterclockwise, it can contact the buffer anti-collision rubber, thereby reducing the working noise of the door closer when closing the door.

[0006] The working principle of the utility model is that when opening the door, pressing the touch switch forces the locking slide bar to slide out of one end of the L-shaped slide groove at the left end of the slider, that is, entering the unhooking state, and the slider moves under the action of the reset spring, so that the pulley at the right end of the slider slides out of the bayonet at the tail end of the swing arm to complete the door opening action, when the tail end of the swing arm swings to contact the buffer seat and forces the buffer seat to move, the two hydraulic buffers and buffer springs on the buffer seat provide buffering force for the buffer seat; when the door closing angle reaches 30 degrees, the pulley of the slider cooperates with the bayonet of the swing arm, the door automatically closes, and when closing, the tail end of the swing arm contacts the buffer anti-collision rubber to reduce the impact noise during closing.

[0007] The utility model has the advantages of more reasonable design and layout, improved door opening force and buffering force when opening and closing the door, low noise during the working process and long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a three-dimensional schematic diagram of the overall structure of the utility model.

[0009] Figure 2 It is a three-dimensional schematic diagram of the internal structure of the utility model. DETAILED DESCRIPTION

[0010] according to Figure 1 , Figure 2 As shown, the utility model comprises a housing 1, a swing arm 2, a touch switch 3, a touch spring 5, a slider 6, a locking slide bar 7, a reset spring 8, a buffer seat 9, a hydraulic buffer 10, a buffer spring 11, a buffer anti-collision rubber 12, and a pulley 13. The slider 6 is installed in the middle of the top of the housing, the tail end of the swing arm 2 is hingedly installed at the right end of the housing 1, and the buffer anti-collision rubber 12 is fixed to the right side of the tail end of the swing arm 2 in the housing 1; the buffer seat 9 can be slid left and right in the housing 1 and is located below the slider 6 through the slide bar 4, and the left and right sides of the buffer seat 9 Hydraulic buffers 10 are respectively installed at the ends, and a buffer spring 11 is sleeved on the sliding rod protruding to the right end of the buffer seat 9. When the tail end of the swing arm 2 swings clockwise, it can contact the buffer head at the right end of the buffer seat 9, and make the buffer seat 9 slide to the left. The hydraulic rods of the left and right hydraulic buffers in the buffer seat 9 protrude to the left and right ends of the buffer seat respectively and contact the inside of the shell 1, providing buffering force for the buffer seat when the buffer seat 9 slides; when the tail end of the swing arm 2 swings counterclockwise, it can contact the buffer anti-collision rubber 12, thereby reducing the working noise of the door closer when closing the door.
