Abstract

The utility model provides an improved adjustable balancing support foot suitable for a large machine. A screw rod is penetrated through a supporting bearing and is inserted in a through hole of a seat body, a supporting adjusting block fixed on the screw rod is arranged on the supporting bearing so as to increase load bearing force, a screw is fixed with the screw rod inserted into the through hole of the seat body through a round station hole of the seat body so as to cause a space between the screw rod and the seat body to be steable, and the supporting bearing has reverse thrust suitable for heavy machine. The screw can also be replaced by a rivet and a pin; the clamping spring is clamped into a groove of the screw rod for fixing the screw rod so as to form another form of the utility model, and operation is convenient.

Description

A kind of adjustable and balancing leg

The utility model relates to a kind of adjustable and balancing leg, is applicable to the heavy machinery that needs adjustment, is specially adapted to objects such as large-scale rack.

The balance leg is installed in the base of object such as big machinery, plays adjustment and supporting effect, according to the knowledge of the applicant, its screw rod of the leg of being sold and base come off easily on the market, less stable, and rotation is dumb between screw rod and the base, is not easy to the balance adjustment of heavy machinery.

The purpose of this utility model provides a kind of improved adjustable and balancing leg, improves the steadiness of leg, and screw rod rotates more nimbly and freely during adjustment, increases bearing capacity.

For solving above-mentioned task, the utility model provides following technological scheme: a kind of adjustable and balancing leg, comprise screw rod 1, pedestal 2 and spring bearing 4, screw rod 1 is in the through hole of the pedestal 2 of a spring bearing 4 insertions and its close proximity, be provided with and support regulating block 5 and be fixed in screw rod 1 and place on the spring bearing 4, the through hole lower end of pedestal 2 is platform hole, garden 2a, and the lower end of screw rod 1 is in the 2a place screens of platform hole, garden.

At 2a place, platform hole, garden rubber gasket (6a, 6b), spring pad 7 are set, and with screw 3 with the screens that is threaded with screw rod 1 of rubber gasket (6a, 6b), spring pad 7.

On the screw rod 1 at 2a place, platform hole, garden, open screw slot 9, be embedded in jump ring 8 screens at screw slot 9.

Pedestal 2 is enclosed within on the rubber cushion seat 21 by steel bowl 22 with holes to be formed.

Spring bearing 4 is the one group of steel ball that places pedestal 2 tops.

The advantage of the utility model design is: spring bearing 4 itself exists the unilateral thrust effect can reduce machinery direct pressure and friction to pedestal 2, support regulating block 5 simultaneously and have supporting effect, can increase stress surface, reduce the strand power that exists between screw rod 1 and the pedestal 2, thereby improve the bearing capacity and the steadiness of leg, make it easy to adjust, rotate flexibly, overcome the defective that former product screw rod and pedestal can come off, can bear heavier machinery.The adjustable and balancing leg of another kind of structure is to be stuck in screw slot 9 internal fixation screw rods 1 with jump ring 8, and it operates more convenient, and same bearing capacity and steadiness are arranged.

Below by embodiment, and in conjunction with the accompanying drawings the utility model is further described:

Fig. 1 is a kind of structural profile schematic representation of adjustable and balancing leg.

Fig. 2 is the local enlarged diagram that supports annexation between regulating block, spring bearing, the pedestal among Fig. 1.

Fig. 3 is the structural profile schematic representation of another kind of adjustable and balancing leg.

Fig. 4 is a jump ring structural representation among Fig. 3.

Fig. 5 is the structural representation of screw slot among Fig. 3.

Embodiment one: in conjunction with Fig. 1 and Fig. 2, a kind of adjustable and balancing leg, comprise screw rod 1, pedestal 2, support regulating block 5, spring bearing 4, rubber gasket (6a, 6b), spring pad 7 and screw 3, screw rod 1 is passed spring bearing 4 and insert in pedestal 2 through holes, screw rod 1 bottom has one to support regulating block 5 and fix with it, and this support regulating block 5 is placed on the spring bearing 4 just play a supportive role, spring bearing 4 is formed (see figure 2) by one group of steel ball, it places on the pedestal 2, be enclosed within by steel bowl 22 with holes and form pedestal 2 on the rubber cushion seat 21, rubber cushion seat 21 has a through hole to insert for screw rod 1, the through hole lower end of pedestal 2 is platform hole, garden 2a, the lower end of screw rod 1 is in the 2a place screens of platform hole, the garden of pedestal 2, by rubber gasket (6a, 6b), spring pad 7 and screw 3 are finished screens, with rubber gasket 6a, 6b, spring pad 7 places platform hole, garden 2a, uses screw 3 with rubber gasket (6a, 6b), spring pad 7 is threaded with screw rod 1.

In the present embodiment, screw 3 can also adopt rivet or sheath bolt to replace.For the lighter machinery of weight, also can not adorn spring bearing 4.

Embodiment two: in conjunction with Fig. 3～Fig. 5, another kind of adjustable and balancing leg, comprise screw rod 1, pedestal 2, support regulating block 5, spring bearing 4, screw slot 9 and jump ring 8, present embodiment is except carrying out screens at 2a place, platform hole, the garden of pedestal 2 by rubber gasket (6a, 6b), spring pad 7 and screw 3 in the lower end of screw rod 1 with embodiment one, change into and open screw slot 9 in the lower end of screw rod 1 and carry out with jump ring 8 outside screens fixes, other structure is with embodiment 1.

During clamping, screw rod 1 is inserted in the through hole of pedestal 2, and make screw slot 9 stretch out platform hole, the garden 2a of through hole below, jump ring 8 is strutted and snaps in the screw slot 9 shown in Figure 5 screw rod 1 is connected and fixed with general utility tool two hole 8a, 8b (see figure 4) from the jump ring 8.This kind method is simple to operate, and same bearing capacity and steadiness are arranged.
