Description
Technical field
The utility model relates to a kind of bounce-back device, and particularly a kind of combined type advances the bounce-back device.
Background technology
Existing bounce-back device is all stable inadequately when in use, and service life is short, complicated operation in the time of use.
Summary of the invention
At the shortcoming of prior art, the utility model provides a kind of novel combined type to advance the bounce-back device.
To achieve these goals, the measure taked of the utility model:
A kind of combined type advances the bounce-back device, comprise loam cake, backstay, location hook, lower cover and spring, backstay is arranged at the head of loam cake, its circular hole is inserted the cylinder of loam cake, head places below the compressing tablet of loam cake, and location hook is arranged at loam cake inside, and its underpart is provided with gathering sill, the backstay afterbody is provided with bossed small column, and small column slides in the gathering sill of location hook.The afterbody of location hook and loam cake is provided with spring groove, and location hook is connected by spring with loam cake;
Described backstay material is a cast zinc alloy;
Described location hook material is the POM material.
The beneficial effects of the utility model: can advance expansion, simple in structure, cost is low, be convenient to operation, long service life.
Description of drawings
Fig. 1, blast structural representation of the present utility model.
Fig. 2, working state schematic representation of the present utility model.
The specific embodiment
A kind of combined type advances the bounce-back device, comprises loam cake 1, backstay 2, location hook 3, lower cover 4 and spring 5, and backstay 2 is arranged at the head of loam cake 1, and its circular hole is inserted the cylinder of loam cake 1, and head places below the compressing tablet of loam cake 1; Location hook 3 is arranged at loam cake 1 inside, and its underpart is provided with gathering sill, and backstay 2 afterbodys are provided with bossed small column, and small column slides in the gathering sill of location hook 3; The afterbody of location hook 3 and loam cake 1 is provided with spring groove, and location hook 3 and loam cake 1 are connected by spring.Operation principle of the present utility model: location hook 3 moves forward under the effect of power F, the small column of backstay 2 afterbody projections slides in the gathering sill of location hook 3, when moving to extreme position (operating position), location hook 3 cancels load F, location hook 3 retreats under the spring tension effect, the small column of backstay 2 is static when sliding into the anchor point of location hook 3 gathering sills, and location hook 3 is in running order; Imposed load F once more when resetting, the small column of backstay 2 leave the anchor point of location hook 3 gathering sills under the guiding of location hook 3 gathering sills, location hook 3 retreats to reset position under the spring tension effect; Loam cake 1 is provided with anchor point, and location hook 3 is laid in a little pulling force that resets under the spring tension effect.Described backstay 2 materials are cast zinc alloy (ZZnAl4-1).Described location hook 3 materials are POM (polyformaldehyde-be commonly called as and match steel) material.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in this area.
