The utility model relates to engineering machinery field, is specially a kind of rotary locking device.
Two, background technique
In recent years, there are a lot of operation mechanisms to need locking device in the engineering machinery field, realize the locking between fixing device and the executor.The current bolted on connection that generally adopts, there is the shortcoming of installing, dismantling inconvenience in actual applications, especially in case of emergency needs the device of the state of devoting oneself to work immediately, can not realize quick release and locking during with Bolt Connection, had a strong impact on working efficiency, may cause meeting accident.
Three, summary of the invention
In order to overcome the narrow limitation of existing locking device, the utility model provides a kind of rotary locking device, and this operating mechanism has convenient disassembly, advantages of simple structure and simple.
The utility model solution is as follows:
A kind of rotary locking device comprises running shaft, and this running shaft one end has projection; The running shaft overcoat is fixed with handlebar, and handlebar is provided with set lever, and the end of this set lever is provided with projection spring housing is located on the set lever; Running shaft is arranged with axle sleeve outward, and this axle sleeve is provided with disk, has keeper with the set lever corresponding position on this disk.
Projection is set on the running shaft, offers the identical slotted eye of shape for lugs therewith on the worktable, running shaft is inserted to revolve behind the worktable turn 90 degrees, the projection of setting can guarantee that running shaft can not break away from worktable; The set lever that is provided with can be fixed running shaft, breaks away from worktable because of rotation when having prevented this device work.
Above-mentioned a kind of rotary locking device, the tip protrusion that running shaft is big is taper, these taper both sides are the plane.
The conical surface that is provided with can play good leading role in the time of can installing, and the side is that the design on plane can guarantee that running shaft can not break away from worktable, plays good supporting effect with after its rotation.
Above-mentioned a kind of rotary locking device is provided with rotating handle on operating lever.
The rotatable handle that is provided with makes the spinning movement of running shaft convenient, laborsaving.
Above-mentioned a kind of rotary locking device is provided with adjusting nut in the end of running shaft.
Adjusting nut is set, can realizes locking force by adjusting nut.
Above-mentioned a kind of rotary locking device, described set lever comprises locking head and lock shaft, the two is hinged; The projection of set lever can be nut, and this nut is threaded with lock shaft.
The lock shaft that is provided with can be with on sheathed this lock shaft of spring, then it is passed behind the handlebar hingedly with locking head, makes spring be in impaction state, guarantees that set lever can stretch in the keeper in the disk.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a perspective view of the present utility model.
Five, embodiment
As shown in Figure 1 and Figure 2, the 1st, running shaft, the 11st, the projection of running shaft, the 2nd, worktable, the 21st, slotted eye, the 3rd, handlebar, the 31st, set lever, the 311st, locking head, the 312nd, lock shaft, the 32nd, rotating handle, the 4th, spring, the 5th, axle sleeve, the 6th, disk, the 61st, keeper, the 7th, adjusting nut.
A kind of rotary locking device comprises running shaft 1, and these running shaft 1 one ends have projection 11, offers the identical slotted eye 21 of projection 11 shapes therewith on the worktable 2; Running shaft 1 overcoat is fixed with handlebar 3, and this handlebar 3 is provided with set lever 31, and the end of this set lever 31 is provided with projection spring 4 is sheathed on the set lever 31; Be arranged with axle sleeve 5 outside the running shaft 2, this axle sleeve 5 is provided with disk 6, and the projection corresponding position with set lever 31 on this disk 6 has keeper 61.
The tip protrusion of running shaft 1 is taper, and these taper both sides are the plane, are provided with rotating handle 32 on operating lever 3, are provided with adjusting nut 7 in the end of running shaft 1, and described set lever 31 comprises locking head 311 and lock shaft 312, and the two is hinged.
During locking, with running shaft 1 under the guiding of coned face, its planar end surface is inserted in the slotted eye 21 of worktable 2 cooperations, be pressed into the ear end face of conical head, revolve with handle with sleeve 32 driven rotary operating levers 3 then and turn 90 degrees, the lock shaft 312 of set lever 31 is realized locking at the keeper 61 that is inserted into automatically under the effect of spring 4 on the disk 6.
During release, pull out set lever 31 and make lock shaft 312 break away from keeper 61 on the disks 6, revolve and turn 90 degrees with rotating rotating handle 32 driven rotary operating levers 3 simultaneously, outwards spur operating lever 3 again and make running shaft 1 break away from the slotted eye 21 that worktable 2 cooperates, the realization release.
The utility model can be selected suitable running shaft 1 according to the weight of the device that is locked, and locking force can realize by adjusting nut 7, and has good stability, simple in structure, easy to use, characteristics such as cost is low.
The utility model is not limited to above mode of execution, other deformation ratios as: disk is replaced with other shapes, changes running shaft end nipple shape and rise or the like to change and be considered as not breaking away from the utility model essence.
