Description

Bridge type hydraulic buffer hinge

Technical Field

The utility model relates to a bridge type hydraulic cushion hinge.

Background

The existing bridge type hydraulic buffering hinge is shown in figures 1 and 2 and comprises a first bottom plate 1, a second bottom plate 2 and a connecting rod transmission structure 3, the connecting rod transmission structure 3 connects the first bottom plate and the second bottom plate at two ends of the connecting rod transmission structure, the contraction of the connecting rod transmission structure realizes the contraction of the first bottom plate and the second bottom plate, the expansion of the connecting rod transmission structure realizes the expansion of the first bottom plate and the second bottom plate, a hydraulic cylinder 4 is arranged between the connecting rod transmission structure 3 and the first bottom plate 1, one end of the hydraulic cylinder is rotatably installed on the first bottom plate, the other end of the hydraulic cylinder is rotatably connected with the connecting rod transmission structure, the existing structure is that one end of the first bottom plate is overturned through stamping to form an installation position, and the hydraulic cylinder is fixed on the installation position. Because the first bottom plate is only simply turned out of the installation position on the flat plate, the pull force generated by the hydraulic cylinder is very large in the opening and closing process of the hinge, so that the first bottom plate is deformed and upwarps under the action of the pull force, and the following problems are caused.

Firstly, after the hinge is assembled, the first bottom plate is deformed due to manual opening and closing inspection.

Secondly, the deformation of the first bottom plate can directly influence the buffering effect of the hinge, and some of the first bottom plate even lose the buffering effect, so that a lot of defective products and waste products are caused.

And the deformation of the bottom plate affects the appearance and is not accepted by users.

In order to solve this problem, the reinforcing holes 5 are additionally formed at the outer end of the first base plate by widening the holes, and the holes are fixed to the equipment by screws, which causes a problem.

(1) If the user is on a piece of furniture, the side plate on which the damping hinge is mounted needs to be widened by one time compared with the side plate of the hinge without the damping function. Increasing the cost to the user. The user does not accept.

(2) When the buffer hinge is used on other special equipment, due to the widening of the bottom plate, a user cannot use the buffer hinge due to insufficient space, but the user needs the buffer door-closing requirement.

Disclosure of Invention

Therefore, an object of the utility model is to provide a high, stable, with low costs, the installation is simple, the little bridge type hydraulic cushion hinge of installation area of qualification rate.

The purpose of the utility model is realized like this.

A bridge type hydraulic buffer hinge comprises a first bottom plate, a second bottom plate and a connecting rod transmission structure, wherein the first bottom plate and the second bottom plate are connected at two ends of the first bottom plate and the second bottom plate through the connecting rod transmission structure, the first bottom plate and the second bottom plate are contracted through contraction of the connecting rod transmission structure, the first bottom plate and the second bottom plate are expanded through expansion of the connecting rod transmission structure, a hydraulic cylinder is arranged between the connecting rod transmission structure and the first bottom plate, one end of the hydraulic cylinder is rotatably arranged on the first bottom plate, the other end of the hydraulic cylinder is rotatably connected with the connecting rod transmission structure, the first bottom plate located below the connecting rod transmission structure is formed through stamping and bending to form a circle of supporting wall higher than the first bottom plate, the supporting wall is perpendicular to the first bottom plate, the hydraulic cylinder is installed on the supporting wall through a pivot, a first mask strip located in the connecting rod transmission structure above the first bottom plate is rotatably connected with the supporting wall, and the periphery of the first mask strip is located on the outer side of the supporting wall.

The technical scheme can be further perfected as follows.

The supporting wall is of a complete circle structure without disconnection.

The pivot is mounted on the support wall.

One of the designs of the utility model is that the middle of the first bottom plate is formed by multiple punching and bending to form a circle of supporting wall for installing the hydraulic cylinder, because the supporting wall is in a ring shape continuously, the strength is high, the phenomenon that the outer end part of the first bottom plate is upwards warped before the hinge is opened and closed can not occur, because the supporting wall is also flanged for 90 degrees, the hinge is firmer, the design of the first bottom plate structure ensures that the first face cover strip in the connecting rod transmission structure can rotate only by being arranged on the outer side of the supporting wall, the two-point design not only solves the deformation problem of the first bottom plate, but also does not need to lengthen the first bottom plate and increase a reinforcing screw hole for independent fixation, therefore, the length of the first bottom plate can be terminated at the outer side of the supporting wall, the length of the first bottom plate is shortened, the production cost is low, and more importantly, a user does not use the mounting side plate with doubled width. The cost is saved for the user, and the installation is also simple.
