Abstract

The utility model relates to an eccentric locking mechanism, in particular to an eccentric locking mechanism used for a rotary door switch, which comprises an eccentric bushing. The axial direction of the eccentric bushing is eccentrically provided with an eccentric hole; an eccentric bushing connecting pin shaft is movably arranged in the eccentric hole; the eccentric bushing connecting pin shaft is fixed on a rotary door; one side of the eccentric housing is fixedly connected with a handle; the outer side of the eccentric housing of the upper part of the handle is movably sleeved with a hanger connecting sleeve which is coaxial with the eccentric bushing; one side of the hanger connecting sleeve, which faces away from the handle, is fixedly connected with a hanger; and the hanger is hung and buckled on the hanger connecting pin shaft matched with the hanger on a fixed mount. The utility model has simple structure, convenient operation, labor saving, reliable connection, low cost and long service life and does not use energy sources.

Description

A kind of Camlock mechanism

Technical field:

The utility model relates to a kind of Camlock mechanism, especially a kind of Camlock mechanism that is used for the rotary door switch.

Background technology:

At present, the rotary door switch mostly adopts pneumatic or the hydraulic-driven switch, the control mode complexity, and power consumption is big, the cost height.

The utility model content:

The utility model provides a kind of Camlock mechanism, and it is simple in structure, and is easy to operate, laborsaving, does not use the energy, connects reliably, and cost is low, and long service life has solved problems of the prior art.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises an eccentric bushing, be provided with an eccentric orfice in the eccentric bushing off-centre that makes progress, be movably equipped with an eccentric bushing in the eccentric orfice and connect bearing pin, eccentric bushing connects bearing pin and is fixed on the rotary door, is fixed with one handle in a side of eccentric bushing; Be movably installed with in the eccentric bushing on the handle top outside one with the hook adapter sleeve of eccentric bushing concentric, on the hook adapter sleeve, be fixed with a hook with the opposing side of handle, buckle and be connected on the bearing pin with the hook of hook cooperation on the fixed mount.

The utility model is simple in structure, and is easy to operate, laborsaving, adopts handle to drive hook by eccentric bushing and moves and fix or open rotary door, do not use the energy, connects reliably, and cost is low, long service life.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the structural representation of the utility model eccentric bushing.

Fig. 4 is that A-A among Fig. 3 is to the sectional structure schematic diagram.

Fig. 5 is the structural representation of hook adapter sleeve.

Fig. 6 is that B-B among Fig. 5 is to the sectional structure schematic diagram.

Among the figure, 1, eccentric bushing; 2, eccentric bushing connects bearing pin; 3, handle; 4, hook adapter sleeve; 5, hook; 6, hook connects bearing pin; 7, eccentric orfice.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

Shown in Fig. 1～6, the utility model comprises an eccentric bushing 1, eccentric bushing 1 axially on off-centre be provided with an eccentric orfice 7, be movably equipped with an eccentric bushing in the eccentric orfice 7 and connect bearing pin 2, eccentric bushing connects bearing pin 2 and is fixed on the rotary door, is fixed with one handle 3 in a side of eccentric bushing 1; Be movably installed with in eccentric bushing 1 outside on handle 3 tops one with the hook adapter sleeve 4 of eccentric bushing 1 concentric, be fixed with a hook 5 with the opposing side of handle 3 on hook adapter sleeve 4, hook 5 buckles at the hooks that cooperate with hook 5 on the fixed mount and is being connected on the bearing pin 6.

Eccentric bushing 1 is connected bearing pin 2 formations and relatively rotates with eccentric bushing, hook 5 is connected bearing pin 6 formations and relatively rotates with hook.

Axis of rotation after handle 3 and eccentric bushing 1 are fixing is identical with axis of rotation after hook 5 and hook adapter sleeve 4 are fixed, and this axis of rotation is connected bearing pin 2 with eccentric bushing on the eccentric bushing 1 center line has certain eccentric distance.

During use, clockwise rotate handle 3, because the effect of eccentric bushing 1, eccentric bushing 1 drives hook 5 by hook adapter sleeve 4 and moves right, hook 5 buckles at the hook on the fixed mount and connects on the bearing pin 6, and the tension rotary door is fixed on the fixed mount, and this moment, rotary door was handled closed condition; When rotating counterclockwise handle 3, the axis of rotation of eccentric bushing 1 is moved to the left, and is moved to the left by hook adapter sleeve 4 drive hooks 5 and leaves hook connection bearing pin 6, and this moment, rotary door was in open mode.The utility model adopts handle to drive hook by eccentric bushing and moves and fix or open rotary door, does not use the energy, connects reliably, and easy to operate, laborsaving, cost of production is low, long service life.

The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
