Detailed Description
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown.
Referring to fig. 1-7, the present invention provides a damping hinge, including: the transmission support comprises a transmission support 1, a guide block 2, a first buffer device 3, a second buffer device 4, a rotating piece 5 and an elastic piece 6, wherein the transmission support 1 is movably arranged on the guide block 2, a mounting groove is formed in the transmission support 1, the guide block 2 is positioned in the middle of the transmission support 1, the mounting groove is divided into a first mounting groove 11 and a second mounting groove 12 which are used for mounting the first buffer device 3 and the second buffer device 4 respectively, the rotating piece 5 is rotatably arranged at one end of the transmission support 1, and two ends of the elastic piece 6 are fixedly arranged at the other ends of the guide block 2 and the transmission support 1 respectively; the rotation of the rotating part 5 can enable the transmission bracket 1 to move, and then the elastic part 6 is driven to stretch, and the first buffer device 3 and the second buffer device 4 can provide opposite damping in the stretching direction of the elastic part 6, so that the stretching speed of the elastic part 6 is reduced. The elastic piece 6 can stretch when the door is opened and closed, the first buffer device 3 and the second buffer device 4 are arranged, opposite buffer force can be provided in the stretching direction of the elastic piece 6, the stretching speed of the elastic piece 6 is reduced, the door opening and closing process has a buffer effect, noise generated when the door is opened and closed is eliminated, the use comfort level is improved, the problem that a hinge is greatly impacted when a door body is quickly opened can be avoided, the internal structure of the hinge is prevented from being damaged in advance due to fatigue, and the service life of the hinge is prolonged; compared with a setting mode that the damping assembly is sequentially connected with the tension spring, the damping hinge has the advantages that the first buffer device 3 and the second buffer device 4 for buffering, the transmission support 1 for transmission and the elastic part 6 for automatic closing are integrated, the whole size of the damping hinge can be reduced, and the requirement on the installation space is reduced. Wherein, the middle part is not the right middle of the transmission bracket 1, but the position between the two ends of the transmission bracket 1.
When the door is opened, the rotating piece 5 rotates anticlockwise, the rotating piece 5 drives the transmission support 1 to move leftwards, the elastic piece 6 is compressed, when the guide block 2 acts on the second buffer device 4, the second buffer device 4 can generate buffer force compressed relative to the elastic piece 6, the compression speed of the elastic piece 6 is reduced, noise generated during opening the door is eliminated, and the problem that the hinge is greatly impacted when the door body is quickly opened can be avoided, so that the internal structure of the hinge is prevented from being damaged in advance due to fatigue, and the service life of the hinge is prolonged; when closing the door, the elastic component 6 of compressed kick-backs automatically for the door body can self-closing, and drive transmission support 1 and turn right the motion, and simultaneously, 2 looks of guide block are with 3 effects of first buffer, and first buffer 3 can produce the cushion effect for the elastic component 6 resilience, slows down the speed of the elastic component 6 resilience extension, eliminates the noise that produces when the automatic door that closes, improves use comfort. The above-mentioned clockwise, counterclockwise, left and right directions are all based on the directions in fig. 1 and 2.
The first buffer device 3 is a damper, the second buffer device 4 and the elastic member 6 are both springs, and the elastic force of the second buffer device 4 is greater than that of the elastic member 6. The spring housing of elastic component 6 is located outside transmission support 1, and both ends set firmly respectively in the other end of guide block 2 and transmission support 1, and elastic component 6 is spiral spring for elastic component 6's flexible effort to transmission support 1 in all directions is more even. When the door is automatically closed, because the weight of the door body is generally heavier, the inertia is larger under the reset action of the elastic piece 6, the buffer effect of the damper on the rebound and extension of the spring is good, and the door closing speed can be effectively slowed down; the damper of the present application is a one-way damper. Preferably, the length of the spring of the second damping means 4 is less than the length of the second mounting groove 12 when the door is not opened. When just opening the door, because the fast compression speed of elastic component 6 is not restricted in the stage of just opening the door, the setting that the spring length of second buffer 4 is less than the length of second mounting groove 12 can reach the result of opening the door fast, and when elastic component 6 continued the compression for when the spring length of second buffer 4 is less than the length of second mounting groove 12, under the spring combined action of the spring of second buffer 4 and the spring of elastic component, can effectively slow down the speed of opening the door. When opening the door, the elastic component 6 takes place the compression, because second buffer 4's elasticity is great, and second buffer 4 needs bigger effort with the spring compression of elastic component 6 when equal length, and then produces better buffering effect to the compression of elastic component 6, effectively slows down the speed of opening the door. Compared with a structure for realizing bidirectional buffering through a bidirectional damper, the structure with the unidirectional damper and the spring matched with each other has the advantage of lower cost on the premise of ensuring the realization of bidirectional buffering.
The first mounting groove 11 of the transmission support 1 is further provided with a protection structure bent towards the direction of the notch to prevent the first buffering device 3 from being separated from the first mounting groove 11, and the protection structure can be consistent with the curve of the outer side wall of the first buffering device 3.
