Abstract
The invention relates to a quick release device which comprises a base, scissors type double cranks, an opening pin and a release screw. The middles of the scissors type double cranks are hinged onto the base, one end of the opening pin is connected with a spring, the opening pin is arranged on the inner sides of the upper portions of the double cranks, inwardly protruded fixture blocks are arranged on the lower portions of the double cranks, a clamp is arranged at one end of the release screw, a spring penetrates a body of the release screw, the clamp is clamped with the fixture blocks, and the spring of the body of the release screw is butted to the base so as to be in a compressed state. The quick release device has the advantages that two connected objects can be safely and quickly separated from each other by the aid of the quick release device, and the quick release device is simple in structure.
Description
technical field:
The present invention relates to a kind of linkage structure, the linkage structure that especially can discharge fast.
background technique:
In workpiece transportation process, need the amount of the charging of feeding device to control, make feeding device need to depart from fast standing part, the quick release device using is now to control by the Weight Loaded of hopper mostly, generally need now people's changable mouth, inhomogeneous and have a potential safety hazard but beam exist is controlled in manual operation.
summary of the invention:
The technical problem to be solved in the present invention is: the quick release device that a kind of precise control and safety are provided.
In order to solve the above problems, technological scheme provided by the invention is, quick release device, comprises that matrix, middle part are hinged on the scissors type double-crank on matrix, and what one end connected by spring struts pin and discharge screw rod, describedly strut the inner side that pin is arranged on double-crank top, the bottom of described double-crank is provided with inwardly outstanding fixture block, discharge screw rod one end and be provided with dop, and shaft is installed with Compress Spring, described dop and fixture block clamping, Compress Spring props up matrix.
The advantage of quick release device of the present invention is: owing to strutting pin and be arranged on the inner side on double-crank top, by external force, pull and strut pin, strut pin and strut double-crank and open, crank is rotated by articulating point, and the fixture block of crank bottom is to two side shiftings, discharged the dop of bolt, because discharge the spring of bolt sleeve in compressive state, the moment discharging at dop, discharge bolt and eject fast, discharge two and connected object, reached the object of quick release.
Preferably, consider that discharging bolt need to repeatedly use, described release screw rod outer installment has screw rod barrier, by barrier, can prevent that bolt from departing from spring and dropping when discharging.
Finally, depart from the inner side of crank in order to prevent from strutting pin, described crank top is provided with and stops the baffle plate that struts pin, is undertaken spacingly making of strutting that pin moves by baffle plate, can effectively prevent from strutting the inner side that pin skids off double-crank.
accompanying drawing explanation:
Fig. 1: be the quick release device of mentioning in the embodiment of the present invention.
embodiment:
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Quick release device as shown in Figure 1, comprise that matrix 1, middle part are hinged on the scissors type double-crank 2 on matrix 1, what one end connected by spring struts pin 3 and discharges screw rod 12, describedly strut the inner side that pin 3 is arranged on double-crank 2 tops, the bottom of described double-crank 2 is provided with inwardly outstanding fixture block 7, discharge screw rod 12 one end and be provided with dop 6, and shaft is installed with Compress Spring 10, described dop 6 and fixture block 7 clampings, Compress Spring 10 props up matrix 1.
Owing to strutting pin 3 and be arranged on the inner side on double-crank 2 tops, strut pin 3 and be connected with external connection power 5 devices by pull bar, when pulling, strut pin 3, strut pin 3 and strut double-crank 2 and open, double-crank 2 is rotated by articulating point, the fixture block 7 of crank bottom, to two side shiftings, unclamps the dop 6 that discharges bolt, because the spring that discharges bolt sleeve is in compressive state, the moment discharging at dop, discharge bolt and eject fast, discharged charging carriage 8 and fixed plate 11, reached the object of quick release.
Consider that discharging bolt need to repeatedly use, described release screw rod outer installment has screw rod barrier 9, by barrier 9, can prevent that bolt from departing from spring and dropping when discharging.Described crank top is provided with and stops the baffle plate 4 that struts pin, is undertaken spacingly making of strutting that pin moves by baffle plate 4, can effectively prevent from strutting the inner side that pin 3 skids off double-crank 1.
Above-described is only the preferred embodiment of the present invention.It should be noted that; for a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practicability.
Claims (3)
