Abstract
Provided is a button type locking handle. The button type locking handle comprises a movable joint, a fixed joint, a hinge shaft and a handle rod. A cam is arranged at one end of the handle rod, the hinge shaft is used for movably connecting the movable joint and the fixed joint, and the cam end on the handle rod is connected with one end portion of the hinge shaft through a hinge pin. The button type locking handle is characterized in that an empty groove is arranged in the cam end of the handle rod, and the end portion of the hinge shaft connected with the cam end of the handle rod is placed in the empty groove. A button is arranged in the empty groove and movably sleeved on the end portion of the hinge shaft arranged in the empty groove, and a spring is arranged between the button and the end portion of the hinge shaft.
Description
Technical field
The invention belongs to armarium manufacturing technology field, relate to the retaining mechanism in manual control connection joint on the operation table, be specifically related to a kind of handle of operation table joint locking mechanism.
Background technology
Operation table need to be adjusted different incline direction and angle according to the requirement of different operation positions in use, and this adjustment realizes by the angle of turning back in control operation table joint.Control at present the adjustment mode of the different joint angles of operation table, mainly contain two kinds: a kind of is control and the locking of the power-driven mechanisms such as oil cylinder, electric cylinder, this mode complex structure, and cost is higher.Another kind is manually to control the joint angles adjustment, then by manual locked hinge joints chain.At present, the place uses the mode in manual locked joint at the joint hinge, mainly contains the forms such as screw knob, cam handle.Wherein, screw knob structure when locking complex operation, and also the joint is during along the pin joint radial force, and the power value of the locking knob that needs is very large, and is very inconvenient during user's practical operation.And traditional cam handle retaining mechanism, simple in structure, as shown in Figure 1, comprise movable joint 1, fixing joint 2, hinge axis 3, handlebar stem 4, one end of handlebar stem 4 is provided with cam 41, hinge axis is flexibly connected movable joint 1 and fixing joint 2, cam end on the handlebar stem 4 is connected with the end of hinge axis 3 by pivot pin 5, directly pass through squeeze grip bar 4 during use, drive hinge axis 3 axially-movables, movable joint 1 is close to fixing joint 2, and so that cam 41 surface pressure fasten 2 surfaces, joint, locks.But this mode is higher to the processing request of cam face, and squeeze grip need to be than great force value, and exists because misoperation and other fortuitous events, causes easily the risk of joint release so that handle is broken into two with one's hands.
Summary of the invention
Originally benefit from novel purpose and be defective for present cam-type operation table joint lock handle, a kind of novel manual locking handle is provided, by less operating physical force value, namely can easily realize locking or release, can eliminate simultaneously the risk that handle that misoperation causes unclamps.
Technical scheme of the present invention is as follows:
A kind of button-type locking handle, comprise movable joint, fixing joint, hinge axis, handlebar stem, one end of described handlebar stem is provided with cam, described hinge axis is flexibly connected movable joint and fixing joint, cam end on the described handlebar stem is connected with an end of hinge axis by pivot pin, it is characterized in that: the cam end on the described handlebar stem is provided with a dead slot, and the end of the hinge axis that is connected with cam end on the described handlebar stem is positioned at described dead slot; Be provided with button in the described dead slot, described button activity is socketed in the described end that is positioned at the hinge axis of dead slot, and is provided with spring between described button and hinge axis end.
The internal diameter of described dead slot is greater than the bore of dead slot.
The frame mode that the present invention adopts, it is the folding operation of carrying out handle by pressing spring button, because the tension force effect of spring, reduced the processing request of handle to cam face, reduce the operating physical force value, made things convenient for locking and unlocking operation to handle, just can carry out release by button simultaneously, the risk of also having avoided misoperation to cause handle automatically to unclamp has improved the safety of mechanism.

Fig. 3 is the locking state sketch map of an embodiment of the present invention
The specific embodiment
As shown in Figure 1 and Figure 2, the present invention includes movable joint 1, fixing joint 2, hinge axis 3, handlebar stem 4, one end of described handlebar stem 4 is provided with cam 41, described hinge axis 3 is flexibly connected movable joint 1 and fixing joint 2, the cam end of described handlebar stem 4 is connected with an end of hinge axis 3 by pivot pin 5, cam end on the described handlebar stem is provided with a dead slot 42, and the end of the hinge axis that cam end described and handlebar stem 4 is connected is positioned at dead slot.The internal diameter of dead slot 42 is greater than the bore of dead slot.Be provided with button 6 in the described dead slot 42, described button 6 is actively socketed on the end of the hinge axis 3 that is positioned at dead slot, makes the button 6 can be along hinge axis 3 axially reciprocatings, and is provided with spring 7 between described button 6 and hinge axis 3 ends.
The present invention is when release, when namely being changed to state shown in Figure 1 by state shown in Figure 2, to dead slot 42 interior pressing buttons 6, spring 7 is compressed, make button 6 enter dead slot 42 fully, upwards lift simultaneously the bar 4 that pulls handle, drive hinge axis 3 by pivot pin 5 and move axially, make movable joint 1 away from fixing joint 2, realize release.Because the internal diameter of dead slot 42 is greater than the bore of dead slot, so button 6 is stuck in the dead slot 42 under the drag effect at dead slot mouth edge, and the outside top of the tension force pressure handle hand lever 4 of spring 7 makes handlebar stem 4 keep lifting status, thereby keeps released state simultaneously.
The present invention is when locking, and when namely being changed to state shown in Figure 2 by state shown in Figure 1, squeeze grip bar 4 drives hinge axis 3 axially-movables by pivot pin 5 downwards, makes movable joint 1 near fixing joint 2; Button 6 overcomes the resistance at dead slot mouth edge under external force, and under spring action, the dead slot mouth is ejected in the end of button 6, and this moment, the cam 42 of handlebar stem 4 pressed fixing joint 2, and movable joint 1 is abutted against with fixing joint 2, realized locking.Under locking state, because button 6 ends are positioned at outside the dead slot mouth, block handlebar stem 4 and make handlebar stem rotations that can not arbitrarily make progress, upwards lift the bar that pulls handle even therefore misoperation occurs, misunderstanding can not occur yet lock.
