Detailed description of the invention
nullBelow in conjunction with accompanying drawing, the present invention is further illustrated,See shown in Fig. 1 ~ 5,Multifunctional desk table surface height locking device,Include the supporting seat 1 of hollow、Height regulating rod 2,It is internal that one end of height regulating rod 2 is hinged on supporting seat 1 by bearing pin 3,Supporting seat 1 is internal is provided with the adjustment clamp 4 being fixed on height regulating rod 2、Transversely it is slidably arranged in the lock 5 within supporting seat 1、Promote the operating parts 6 of lock 5 transverse shifting,Operating parts 6 is connected with lock 5,It is outside that the tail end of operating parts 6 stretches out supporting seat 1,Regulate and clamp 4 offers multiple hole clipping 41,In the locked state,The head end of lock 5 is entrapped in one of them hole clipping 41,In the locked state,The head end of lock 5 is entrapped in one of them hole clipping 41,Adjustment clamp 4 is locked,Thus height regulating rod 2 is locked on supporting seat 1,During unblock,It is operated by part 6 to promote lock 5 to regulate clamp 4 dorsad to move to be deviate from by hole clipping 41,So that unlocking between lock 5 and adjustment clamp 4,At this moment height regulating rod 2 freely can rotate, relative to supporting seat 1, the height regulating supporting seat 1,The present invention utilizes coordinating between lock 5 with the hole clipping 41 regulated on clamp 4 to realize lock function,Simple in construction,Latch-up structure is reliable,And utilize operating parts 6 to be unlocked or lock operation,Use easy to operate.
Regulate the multiple hole clippings 41 curved arrangement with bearing pin 3 for axle center on clamp 4 so that adjustment clamp 4 follows each hole clipping 41 when height regulating rod 2 rotates can with lock 5 corresponding matching.Lock 5 is rectangular cylindrical structures, and hole clipping 41 is also corresponding rectangular configuration.
nullIt is provided with between tail end and the supporting seat 1 of lock 5 and lock 5 is locked spring 7 to the pushing tow regulating clamp 4 pushing tow,Operating parts 6 is provided with the pushing tow solution lock dog 61 that lock 5 regulates clamp 4 pushing tow dorsad,Lock 5 is connected to push rod 8,Pushing tow solution lock dog 61 is at push rod 8 and regulates between clamp 4,Pushing tow solution lock dog 61 is provided with the pushing tow inclined-plane 62 that top is pressed on push rod 8,During operating parts 6 upwards action,Pushing tow solution lock dog 61 moves upward,Push rod 8 regulates clamp 4 under the thrusting action on pushing tow inclined-plane 62 dorsad and moves,Lock 5 is released in the hole clipping 41 regulated on clamp 4,Make lock 5 and regulate unblock between clamp 4,At this moment height regulating rod 2 freely can rotate, relative to supporting seat 1, the height regulating supporting seat 1,After altitude mixture control completes,Unclamp operating parts 6,Lock 5 locks at pushing tow and freely snaps under the effect of spring 7 in the adjustment corresponding hole clipping 41 of clamp 4,Can automatically lock,Use more convenient operation.It is internal that the head end of operating parts 6 is hinged on supporting seat 1, upwards pulls operating parts 6 and pushing tow solution lock dog 61 can be driven to move upward.The tail end of operating parts 6 is provided with operation handle 63, facilitates operating parts 6 to be operated.
The front end of lock 5 head end is provided with top and moves back inclined-plane 51, and top is moved back top, inclined-plane 51 and is pressed on hole clipping 41 rear end, and when supporting seat 1 down timing, the rear end face of lock 5 head end is stuck in hole clipping 41, it is necessary to upwards pulls operating parts 6 and could control lock 5 and deviate from hole clipping 41;When supporting seat 1 up timing, inclined-plane 51 and hole clipping 41 rear end phase pushing tow are moved back in the top of lock 5, lock 5 is made to be exited in hole clipping 41 by hole clipping 41 top, hence into released state, the height that freely adjustable supporting seat 1 rises, regulate when supporting seat 1 rises and need not can complete by operating parts 6, use more convenient operation.
nullOwing to the frictional force between lock 5 and hole clipping 41 is often relatively larger,It is operated by part 6 sometimes cannot be ejected in hole clipping 41 by lock 5,Thus cannot unlock,For solving above-mentioned technical problem,Lock 5 of the present invention transversely offers buffering slide opening 52,Sliding the sliding laterally of push rod 8 is connected in buffering slide opening 52,Lock 5 is provided with spacing projection 53 near the position of tail end,It is connected to the push rod 8 unblock buffer spring 9 to lock 5 head end direction pushing tow between push rod 8 and spacing projection 53,During unblock,Operating parts 6 is upwards pulled,Pushing tow solution lock dog 61 is driven to move upward,Push rod 8 regulates clamp 4 under the thrusting action on pushing tow inclined-plane 62 dorsad and moves a segment distance,At this moment unlock buffer spring 9 and be subject to the compression savings energy of push rod 8,And lock 5 may rest in hole clipping 41 without actually entering released state under the effect of frictional force,When making a movement between supporting seat 1 and height regulating rod 2,Lock 5 freely will exit in hole clipping 41 under the elastic force effect unlocking buffer spring 9,Thus actually entering released state,The present invention utilizes unblock buffer spring 9 to play the effect unlocking advance row buffering transition,Prevent the phenomenon that cannot unlock between lock 5 and hole clipping 41 because frictional force is excessive,Solve latching operation more smooth and easy、More reliable.
Certainly, the above is only presently preferred embodiments of the present invention, therefore all equivalences done according to the structure described in present patent application scope, feature and principle change or modify, and are all included within the scope of present patent application.
