Description

Bidirectional buffer

Technical Field

The utility model relates to a door and window accessory technical field, especially a can realize buffer of two-way buffering.

Background

A damper is a device for damping the impact of door movement and slowing down the door movement, and is generally applied to a door that is moved in a horizontal direction. When closing the door, manual application of force is in the door, and the door can strike the door opening fast under the inertia effect to produce huge impact sound. In order to buffer the impact force when the door is closed, a buffer and a stop block are respectively and correspondingly arranged on the door and the door opening, and the buffer is blocked by the stop block to realize the reduction of the moving speed of the door. The buffer commonly used only has the function of one-way buffering, when the door can both-way movement close, then need two one-way buffers of installation just can realize two-way buffer function on the door, but install two one-way buffers simultaneously and can occupy door frame most space on the door, and install a buffer relatively and obviously can spend more manpower, material resources and time, increase the expense even, when meetting the narrow little door of frame and need two-way buffering to close the door, will have little door because of the door frame space is not enough, and can't install two one-way buffers, lead to influencing the result of use of door.

Detailed Description

Referring to fig. 1 to 5, the present invention includes a base 1 having a straight groove 11, pulleys 12 are installed at both ends of the base 1, the pulleys 12 are installed on a guide rail installed on a door opening, the base 1 is connected with a door so that the door can move on the guide rail along with the pulleys 12 through the base 1, a buffer mechanism 2 is installed in the straight groove 11 for reducing the moving speed of the door, the buffer mechanism 2 includes a left slider 21 and a right slider 22 which are oppositely disposed, and a damper 23 and an elastic member 24 which are disposed between and connect the two sliders, the left slider 21 and the right slider 22 are respectively provided with a position limiting member 3 and a slide pin 25 at the top and the side wall thereof, the two opposite side walls of the straight groove 11 are correspondingly provided with guide grooves 13, the guide grooves 13 have left and right and are disposed at both ends of the straight groove 11, the ends of the left and right guide grooves are provided with downward bent portions 14, the slide pins 25 are correspondingly inserted into the guide grooves 13, the left slide block 21 and the right slide block 22 can move along the guide groove 13 in two directions; when the door moves leftwards, the limiting part 3 on the left sliding block 21 is blocked, so that the sliding pin 25 on the left sliding block 21 falls into the corresponding bending part 14, and simultaneously, the limiting part 3 on the right sliding block 22 is blocked to stop moving, but because the door also has moving inertia, the door continues to move in the original direction, the damper 23 and the elastic part 24 are forcibly pulled open by the left sliding block and the right sliding block, and in the pulling open process, the damper 23 and the elastic part 24 respectively generate resistance opposite to the moving direction of the door to slow down the moving speed of the door, and similarly, when the door moves rightwards, the moving speed of the door can be slowed down under the action of the buffer, so that the buffer can realize the bidirectional buffering function, and the bidirectional buffering integrates the functions of two unidirectional buffers on one buffer, so that the installation occupied space of one bidirectional buffer is smaller than that of the two unidirectional buffers, the buffer is favorable for being applied to the small door, the application range of the buffer is expanded, meanwhile, the labor, the material resources and the time are saved when one bidirectional buffer is installed compared with the two unidirectional buffers, the cost is also reduced, and therefore, the bidirectional buffer is more convenient for people to use.

Preferably, the utility model discloses a left slider 21 and right slider 22 are connected with attenuator 23 through connecting pin 26 respectively, and simultaneously, the both ends of connecting pin 26 are outwards extended and fall into guide way 13 in, and connecting pin 26 and sliding pin 25 move in guide way 13 simultaneously together, increase the area of contact between connecting pin 26 and sliding pin 25 and the guide way 13, are favorable to improving the stability that left slider 21 and right slider 22 removed, alleviate the vibration when left slider 21 and right slider 22 removed.

Further, the flange 15 extends outwards from the periphery of the guide groove 13, the flange 15 is in contact with the sliding pin 25 and the connecting pin 26, and the contact area between the flange 15 and the sliding pin 25 and the connecting pin 26 is increased, so that the left slider 21 and the right slider 22 move more horizontally along the guide groove 13, and on the other hand, the flange 15 is arranged to improve the strength of the periphery of the guide groove 13 and reduce the deformation of the periphery of the guide groove 13, so that the two sliders move more smoothly.

The utility model discloses a 3 spacing parts are separated by the elasticity of arranging and detain 31 and stopper 32 around including, the top that elasticity was detained 31 is equipped with the inclined plane 33 to the slope of straight flute 11 both ends, and the root is equipped with sliding pin 25, make elasticity detain 31 downwarping through supporting pressing inclined plane 33, when left slider 21 removes left and the butt is to installing the dog on the door opening guide rail, the dog is detained 31 with elasticity in the same direction as inclined plane 33 and is pushed down, and take sliding pin 25 to go into in the crooked part 14 downwards, the position of left slider 21 has been injectd, and simultaneously, stopper 32 on the right slider 22 is blockked and stop moving by the dog, and the same reason, when the door antiport, right slider 22 moves right promptly, the elasticity that corresponds is detained 31 and stopper 22 also can realize the same effect.

In order to slow down the deformation of the straight groove 11, a connecting plate 16 is then provided at the notch of the straight groove 11 and between the two guide grooves 13 to connect the two opposite side walls of the straight groove 11, since the guide grooves 13 are provided on both opposite side walls of the straight groove 11, and the slide pin 25 and the connecting pin 26 are constantly moved on the guide grooves 13, thereby vibrating both opposite side walls of the straight groove 11, causing both opposite side walls of the straight groove 11 to diverge slowly outward, by installing the connecting plate 16 at the mouth of the straight groove 11, the two opposite side walls of the straight groove 11 are closed inwards, so as to counteract the outward diverging force of the two opposite side walls of the straight groove 11, so that the two opposite side walls of the straight groove 11 are kept in the original shape and are not easy to deform, and the connection plate 16 is disposed between the two guide grooves 13, so that the connection plate 16 avoids the guide grooves 13, the connecting plate 16 is prevented from interfering with the slide pin 25 so as not to affect the smoothness of the movement of the two sliders.

Furthermore, the connecting plate 16 is groove-shaped and matched with the straight groove 11 in shape, bosses 17 are arranged in two opposite side walls of the connecting plate 16 facing the groove, limiting openings 18 are arranged on the two opposite side walls of the straight groove 11 corresponding to the bosses 17, and the bosses 17 are clamped into the limiting openings 18 from the outside, so that the straight groove 11 is clamped and fixed by the connecting plate 16.
