As preferably, described joint pin (11) two ends are welded on respectively on the sidewall of described annulus (8) and pipe box (3).
As preferably, described the first gear (9) and the second gear (10) are angular wheel.
As preferably, described axle sleeve (7) is provided with first handle (4).
As preferably, described lowering or hoisting gear also comprises one and the first nut (6) of being threaded of described screw rod (5), described the first nut (6) lateral surface is provided with second handle (13), and described the first nut (6) is positioned at described annulus (8) top.
(3) beneficial effect
The present invention is compared to prior art, and it has following beneficial effect: drive screw rod can make desktop free lifting by two helical gear engagements; Because annulus is by joint pin and pipe box bridge joint, make lifting device structure firm, strength-enhanced; Retaining mechanism can be locked lowering or hoisting gear, makes desk more firm in use, can not cause desktop lifting generation potential safety hazard because of maloperation; Owing to being respectively provided with a lowering or hoisting gear at left and right sides, and connect by axostylus axostyle axle sleeve structure, make operation more laborsaving, can be applicable to large-scale or heavier table body.
Brief description of the drawings
Fig. 1 is the structure chart of link-type mechanical elevating table of the present invention.
Fig. 2 is the partial enlarged drawing of the A part of Fig. 1.
Fig. 3 is the structure chart at another visual angle of link-type mechanical elevating table of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
A kind of link-type mechanical elevating table as shown in Figure 1, Figure 2 and Figure 3, comprises desktop 1, base 2 and lowering or hoisting gear, and lowering or hoisting gear is two groups, and is located at base 2 both sides, upper surface.
Lowering or hoisting gear comprises intermeshing the first gear 9 of pipe box 3, screw rod 5 and vertical direction and the second gear 10, screw rod 5 is installed in pipe box 3 and top connects desktop 1, pipe box 3 bottoms are connected on base 2, the first gear 9 is threaded by internal thread and screw rod 5 and is installed on pipe box 3 tops, the first gear 9 tops are provided with annulus 8, annulus 8 is set on screw rod 5 and with this screw rod 5 and forms matched in clearance, and annulus 8 is by joint pin 11 and pipe box 3 bridge joints.
The axostylus axostyle 12 that is fixed with horizontally set on pipe box 3 sidewalls, is set with axle sleeve 7 on axostylus axostyle 12, each one second gear 10 that connects in axle sleeve 7 two ends.
Joint pin 11 two ends are welded on respectively on the sidewall of annulus 8 and pipe box 3.
The first gear 9 and the second gear 10 are angular wheel.
Axle sleeve 7 is provided with first handle 4.
Lowering or hoisting gear also comprises a retaining mechanism, retaining mechanism comprise one and the first nut 6, the first nut 6 lateral surfaces of being threaded of screw rod 5 be provided with second handle 13, the first nuts 6 and be positioned at annulus 8 tops.
When work, first retaining mechanism is counterclockwise rotated, retaining mechanism is risen to annulus and form certain spacing, shake first handle drives axle sleeve to rotate, the running of axle sleeve driven gear engaging structure, due to internal thread and the screw rod engagement of the first gear, make screw rod lifting, reach the lifting effect of desktop.When arriving after needed height, retaining mechanism is rotated clockwise, make the lower surface of the first nut fit tightly the upper surface of annulus, just this lowering or hoisting gear can be locked.
