The present utility model will be described in detail with reference to the following embodiments shown in the drawings:
as shown in fig. 1-2, in this embodiment, a fixed pulley 2 force reversing damper 8 is provided, which includes a sliding seat, wherein the sliding seat is used for slidably connecting with a sliding plate, the sliding plate is fixedly provided with a pulling hook, the sliding plate is fixedly connected with a side plate of a drawer, and in the use process, the sliding plate slides back and forth relative to the sliding seat in response to the push and pull of the drawer, wherein the sliding seat includes a tension spring 1, a fixed pulley 2, a sliding block 3, a sliding hook 4 and a base plate 5;
in this embodiment, the sliding groove 6 and the sliding groove 7 are formed in the base plate 5, further explaining that the sliding groove 6 is in a U-shaped structure and is arranged in the base plate 5, the first fixing hole groove 9 is formed in the sliding groove 6, the tension spring 1 is embedded in the base plate 5 through the sliding groove 6, the aperture of the sliding groove 6 is larger than that of the tension spring 1, the tension spring 1 can freely stretch and retract in the sliding groove 6, one end of the tension spring 1 is connected with the fixing Kong Caoka, the second fixing hole groove 10 is formed in the sliding block 3, the other end of the tension spring 1 is connected with the second fixing hole groove 10 in a buckling manner, the tension spring 1 always acts on the upper surface of the sliding block 3, a certain tensile force is applied, and the tensile force of the tension spring 1 can also change according to the position change of the sliding block 3.
In this embodiment, the fixed pulley 2 is rotatably connected with the base plate 5, the fixed pulley 2 is located on the chute 6, the tension spring 1 is horizontally symmetrically bent and half-coated on the side surface of the fixed pulley 2, the tension spring 1 acts on the fixed pulley 2 when stretching or contracting to enable the fixed pulley 2 to rotate to a certain extent, and the fixed pulley 2 acts on assisting the extension and contraction of the tension spring 1.
The slide is broken loose and connected with the base plate 5 because the connection and the disconnection of the slide hook 4 and the pulling hook directly lead to, the slide block 3 is rotationally connected with the slide hook 4, when the slide hook 4 is pulled to the tail end of the sliding groove 7 by the pulling hook, swing deflection occurs, the pulling hook is separated from the pull groove 11 of the slide hook 4, the specific slide hook 4 is provided with the pull groove 11 which is used for being abutted with the pulling hook, the pull groove 11 is formed by inwards recessing the upper surface of the slide hook 4, when the slide hook 4 is pulled to move forwards in the sliding groove 7 by the pulling hook, when the tail end of the sliding groove 7 is reached, the slide hook 4 is further pulled by the pulling hook to cause the deflection limit of the slide hook 4 in the limit area 13, and meanwhile, the pulling groove 11 is horizontally arranged to be pulled out by the pull groove 11. When the sliding plate is reset, the poking hooks move inwards and can be abutted on the sliding hooks 4, when the sliding plate is pushed in further, the poking hooks can promote the sliding hooks 4 to swing upwards again, namely reset, and when the sliding plate is reset, the pull grooves 11 are in clamping connection with the poking hooks again, so that the sliding plate can be connected with the base plate 5 again. It should be noted that a toggle slot is provided at one end of the sliding slot 7, and the toggle slot is used for controlling the rotation swing of the sliding hook 4.
In this embodiment, the sliding block 3 and the sliding hook 4 are both slidably disposed in the sliding groove 7, the substrate 5 is further embedded with a damper 8, the damper 8 includes a piston rod, the piston rod penetrates through the substrate 5 and is fixedly connected with the sliding block 3, some dampers 8 with shorter strokes are preferably adopted, the damper 8 has the function that the drawer can buffer the inertia of pushing when being pushed in, and the sliding hook 4 can hook the poking hook of the sliding plate when being pushed in a certain position to control the drawer to automatically push in and reset.
The specific automatic pull-back and reset working process is as follows: the pulling hook of the sliding plate is separated from the sliding hook 4 before the drawer is pulled back, the sliding hook 4 rotates to a certain extent and is clamped in a limiting area 13 (the limiting area 13 refers to the tail end of the outer side wall formed by inwards sinking of the sliding groove 7) of the base plate 5, when the drawer is pushed in and reaches the position where the pulling hook is abutted against the sliding hook 4, the pulling hook is in buckled connection with a pulling groove 11 of the sliding hook 4 and the pulling hook of the sliding plate again, and the sliding plate is connected with the sliding hook 4 at the moment, so that the sliding hook 4 is pulled to move together when the sliding block 3 is pulled back by a pull ring; the above movement mainly means that the tension spring 1 pulls the sliding block 3 to move inwards. Due to the arrangement of the damper 8, the sliding block 3 is subjected to resistance of the damper 8 when moving inwards autonomously, so that autonomous slow inwards resetting can be realized under the cooperation of the tension spring 1 and the damper 8.
The specific drawer pulling-out process is as follows:
because the end part of the sliding block 3 is integrally formed and laterally extends to be provided with the hinge shaft 12, the sliding hook 4 is provided with a through hole, and the hinge shaft 12 is inserted into the through hole, the sliding block 3 is rotationally connected with the sliding hook 4 through the hinge shaft 12. When the sliding plate is pulled out, the sliding plate moves forwards to dial the hook to control the hook 4 to move in the sliding groove 7, the tension spring 1 is pulled by the piston rod of the damper 8 to extend simultaneously, when the tail end of the sliding groove 7 is reached, the hook 4 is pulled further by the hook to cause the hook 4 to deflect and limit in the limiting area 13, meanwhile, the pull groove 11 is horizontally provided with the hook to be separated from the pull groove 11 in a homeotropic manner and pulled out, and a backward tension is continuously applied to the hook 4 under the elastic restoring force of the tension spring 1, so that the hook 4 is ensured to be limited on the limiting area 13 all the time.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features of the above-described embodiments are not described for brevity, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description, and it is also possible for those skilled in the art to make several variations and modifications without departing from the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
