Abstract
The utility model relates to a simple connecting device for workpiece connection; the device comprises a first cam level (1), a second cam level (2) and a locking sleeve (3); the longitudinal section of the first cam level (1) is in an eccentric external cam shape, and the connecting surface of the first cam level (1) is provided with a semi-circular convex plate I (11), the longitudinal section of the second cam level (2) is in an eccentric external cam shape, the connecting surface of the second cam level (2) is provided with the other semi-circular convex plate II (21), the first cam level (1) and the second cam level (2) form an integral eccentric external cam level after being overlaid by the semi-circular convex plate I (11) and the semi-circular convex plate II (21), the inner wall of the locking sleeve (3) is an eccentric internal cam shape, and the locking sleeve (3) is sheathed at the overlying position of the first cam level (1) and the second cam level (2); the simple connecting device has attractive appearance and convenient operation and does not need any operating tools.
Description
(1) technical field
The utility model relates to a kind of simple connecting device, is used for workpiece and connects.
(2) background technique
At present, the demand that all exists workpiece to connect in each field, traditional workpiece connection is adopted screw and nut or screw rod to add modes such as internal thread spins and is realized, but the mode of screw and nut need use instruments such as spanner to operate, and these modes make easily that when tapped hole pollutes unclean or damages the operation element that connects or break away from is affected owing to all need to use tapped hole to connect.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of easy to operate and reliable simple connecting device of switching performance is provided.
The purpose of this utility model is achieved in that a kind of simple connecting device, includes first cam lever, second cam lever and lock sleeve, and the described first cam lever longitudinal section is eccentric evagination colyliform, and the junction surface of first cam lever is provided with a semicircle shape boss I; The described second cam lever longitudinal section is similarly eccentric evagination colyliform, the junction surface of described second cam lever is provided with another semicircle shape boss II equally, and described first cam lever and second cam lever become an eccentric external cam bar integral body after by semicircle shape boss I and semicircle shape boss II stack; Described lock sleeve inwall is eccentric convex colyliform, and described lock sleeve is placed on stack place of first cam lever and second cam lever.
The utility model simple connecting device, described first cam lever and the second cam lever center have through hole.
The utility model simple connecting device, stack place of described first cam lever and second cam lever is provided with a pin, and first cam lever and second cam lever are hinged by this pin.
Working principle of the present utility model is:
The beneficial effects of the utility model are:
(1) adopt eccentric cam ring and two cooperations that have the eccentric external cam of semicircle shape boss to realize linkage function,, do not need to use any instrument can easily realize connecting than the screw and nut linkage structure, simple to operation;
(2) traditional Placement uses worm structure more, but because the easily contaminated impaired difficulty that causes connecting of screw thread, influence operability, the simple and easy Placement of the utility model has adopted eccentric cam ring to realize being connected with two modes that have the eccentric external cam cooperation of semicircle shape boss, avoid the defective of screw thread, made connection reliability higher.

(5) embodiment
Embodiment one:
Referring to Fig. 1 and Fig. 2, the utility model relates to a kind of simple connecting device, include first cam lever 1, second cam lever 2 and lock sleeve 3, described first cam lever 1 longitudinal section is eccentric evagination colyliform, and the junction surface of first cam lever 1 is provided with a semicircle shape boss I11; Described second cam lever 2 longitudinal sections are similarly eccentric evagination colyliform, the junction surface of described second cam lever 2 is provided with another semicircle shape boss II21 equally, and described first cam lever 1 and second cam lever 2 become an eccentric external cam bar integral body after by semicircle shape boss I11 and semicircle shape boss II21 stack; Described lock sleeve 3 inwalls are eccentric convex colyliform, and described lock sleeve 3 is placed on stack place of first cam lever 1 and second cam lever 2.
Referring to Fig. 3～5, during use, lock sleeve 3 is placed on stack place of first cam lever 1 and second cam lever 2, hold lock sleeve 3 and second cam lever 2 is done counterrotating, make the eccentric external cam of the eccentric cam ring of lock sleeve 3 and second cam lever 2 from certain interval being arranged, reach locking effect up to being close to locking, and in the locking process, the semicircle shape boss I11 of first cam lever 1 and the semicircle shape boss II21 of second cam lever 2 are closely pressed together on together, reach the effect of connection; When need removing locking, only need hold first cam lever 1 or second cam lever 2 rotates to original state relatively with respect to lock sleeve 3, lock sleeve 3 stack place of sliding can be broken away from first cam lever 1 and second cam lever 2 very easily.
Embodiment two:
Embodiment two is with embodiment one difference: described first cam lever 1 and second cam lever, 2 centers have through hole.
Embodiment three:
Embodiment three is with embodiment one and two difference: stack place of described first cam lever 1 and second cam lever 2 is provided with a pin, and first cam lever 1 and second cam lever 2 are hinged by this pin.
Claims (3)
