Abstract
An indifferent equilibrium lifting table belongs to the table lifting control device, which is characterized in that the utility model comprises an indifferent equilibrium mechanism comprising a cam provided with a constant diameter reel on a rotating shaft, a tension spring in anti-clockwise winding on a wire rope of the tension spring of the constant diameter reel and in fixed connection with the constant diameter reel, the left and right wire rope connecting blocks respectively linked with the left and right wire ropes bypassing a fixed pulley and fixed on the large radius of the cam in clockwise turning and the left and right limited blocks with rope holes. The left and right upper side of a cavity are provided with the fixed pulley. The left and right outer flanks are embedded with the limited blocks, and the left lower side is provided with the cam. An adjustment hole of the right side of the top is latched with a metal frame of the tensile spring that is far away from the large radius end of the cam and can be lifted. In the lifting table, four sides are closed and jacketed on the outside of the metal frame, and the left and right inner sides are fixed with the rope holes and tightly pressed downward to the supporting bracket of the connecting blocks of the left and right wire ropes. A locking device in spiral type or universal joint type runs through a circular hole on the table and a long slot of the front baffle of the metal frame from the front or the side. Therefore, the utility model can be lifted in indifferent equilibrium with large controllable distance.
Description
Technical field
But the Lift-type table of indifferent equilibrium belongs to a class apparatus for controlling of lifting field.
Background technology
The patent No. is the Chinese utility model patent of ZL93220229.2, " table class apparatus for controlling of lifting " by name, it discloses in a kind of rotating shaft the table class apparatus for controlling of lifting that constitutes with the cam of isometrical reel and extension spring, it by be connected steel cable on extension spring and the isometrical reel and another root be connected balance with link up with and the steel cable at cam reel long radius place to the opposite moment of the both direction of cam torque generation realize a body in the indifferent equilibrium of vertical spatial position to reach the purpose of lifting.Its shortcoming is: extension spring and cam are on the same horizontal line, and controllable lifting distance is limited; In addition, make balanced body with hook and need reinforcing in addition, inconvenience in use; It does not have a body upright position locking device yet, rely on hook to lock, and is inconvenient during use yet.
Summary of the invention
But the purpose of this utility model is to provide the Lift-type table of a kind of body lifting command range indifferent equilibrium big and easy to use.
Characteristics of the present utility model are: it contains: above-mentioned indifferent equilibrium mechanism, and the left and right upside of inner chamber is equipped with left and right fixed pulley, the left and right outside and is embedded with the adjustment hole that left and right limited block, downside be equipped with cam, relative cam one side in top and hooks the liftable metal frame of extension spring away from this cam long radius end; Four side seals be enclosed within with closing this metal frame outer and the liftable table body of the bearing support that has rope through and push down left and right steel cable contiguous block is tightly downwards being fixed in left and right inboard and from the front or the side pass the locking device of a body circular hole and metal frame front baffle board elongated slot.Read-write desktop or computer desk panel are being fixed in the upper surface of same table body.But under the Lift-type table inversion situation of described indifferent equilibrium, read-write desktop or computer desk panel are being fixed in the metal frame upper surface after described inversion.Described locking device is the spiral locking device that is contained in the front.Described locking device is the universal joint locking device that is contained in the side.In described metal frame bottom left and right gripper shoe is housed.Operation instruction: it has reached intended purposes.
Description of drawings
But the vertical view of the Lift-type table of Fig. 1 indifferent equilibrium.
The A-A of Fig. 2, Fig. 1 is to view.
But the vertical view of the Lift-type table of indifferent equilibrium when Fig. 3, use universal joint locking device.
The specific embodiment
Ask for an interview Fig. 1-Fig. 2.
The utility model is made of following each several part: the table body that is made of header board 1, back plate 2, left plate 3, right plate 4; Have that a plurality of top boards 9 that are used to hook the circular hole of extension spring mouth usefulness constitute and metal frame that can upper and lower slip in above-mentioned table body by front baffle board 5, back plate washer 6, left plate washer 7, right plate washer 8 and right side; Rotating shaft through having isometrical reel and from fore-and-aft direction run through and the cam 10, the end hook that are fixed on the metal frame inner chamber live in to state circular hole on the top board 9 and the other end through being wrapped in steel wire rope 11a and the affixed extension spring 12 of above-mentioned isometrical reel on the above-mentioned isometrical reel widdershins; Lay respectively between the left and right side plate 3,4 of the left and right plate washer 7,8 of above-mentioned metal frame and table body and be separately fixed at left and right bearing support 13a, the 13b that the left and right side plate of a body 3,4 inboards have rope through again; Front and back are installed in left and right fixed pulley 14a, the 14b of above-mentioned top board 9 inner chambers to ground; Be embedded in the outer upside of the left and right plate washer 7,8 of above-mentioned metal frame regularly and extend in above-mentioned metal frame and table body inboard between the left and right limited block 15a, the 15b that have rope through; In table body lifting process, withstand on left and right steel cable contiguous block 16a, 16b below above-mentioned left and right bearing support 13a, the 13b all the time; One end is fixed on the long radius place of the cam 10 that turns to clockwise and the other end is walked around left fixed pulley 14a, passed the steel cable 11b that is fixed on behind the rope through on left limit piece 15a, the left bearing support 13a on the left steel cable contiguous block 16a successively again; One end also be fixed on the long radius end of cam 10 and the other end respectively from contrary, clockwise direction is walked around a left side, right fixed pulley 14a, pass right limit piece 15b behind the 14b more successively, be fixed on steel cable 11c and the positive circular hole that passes header board 1 on the right steel cable contiguous block 16b behind the rope through on the right bearing support 13b, the spiral locking device of the vertical straight trough on the front baffle board 5, the 17th, its handle, in Fig. 3, the 18th, pass on the front baffle board 5 that enters metal frame behind the body right plate 4 the more vertically universal joint locking device of straight trough from the side, the 19th, be fixed on the gripper shoe under the metal frame.
Operation instruction: not only indifferent equilibrium formula ground is adjustable but also bigger for its lifting distance, uses also more convenient.
