Abstract

The utility model belongs to a sport apparatus which overcomes problem that the folding basketball stand with a hydraulic mechanism has complicated structure and a plurality of faults in prior art. The utility model is composed of a basketball backboard, a sport rod component for folding, a base, traveling wheels and a brake. The rod component for folding is a set of parallel four-rod mechanism; a rod component for positioning is arranged between a front and a back upright posts and is used for fixing when the basketball stand stands up. Twelve springs are hung between an extension rod at the lower part of the back upright post and the base; spring prestress is adjustable; the springs are skillfully used, and thus the folding of the backboard stand can be operated by hands. The utility model has the advantages of good property, labor saving in operation and low cost.

Description

Manually folding basketball stands

The utility model belongs to the sports apparatus class, and it is specifically related to a kind of structure of basketball stands of novel foldable.

Basketball is a very universal motion, be subjected to liking of each personage of stratum, therefore can see basketball court and basketball stands everywhere, basketball stands have ordinary populaceization, the senior apparatus that use arena, also promising gymnasium, the basketball stands that use in the gymnasium mostly are removable and collapsible, such apparatus and can improve the service efficiency in place, but also are convenient to transportation and storage.Because the volume and weight of basketball stands is very big, its process effort folding and that prop is very big, the control forms that adopt machinery and hydraulic pressure combination more, though hydraulic control is easy to use, its fault multidimensional is repaiied difficulty, makes troubles to the user.

The purpose of this utility model is the special manually folding basketball stands of this programme----that propose of the technical problem that exists for the basketball stands that overcome aforesaid band hydraulic mechanism, and it has characteristics simple in structure, that cost is low, and rapid operation.

By as above design, the manually folding basketball stands that this programme provided, it is by backboard, connecting rack, the motion rod member of folding usefulness, base, road wheel, brake constitutes, the motion rod member that it is characterized in that it is one group of parallelogram lindage, its rear column with hinge that base connects below the extension is arranged, on extension rod, hang with row's spring, between front column and rear column, be provided with telescopic location rod member, this rod member comprises a core bar and a sleeve pipe, the external diameter of core bar matches with the internal diameter of sleeve pipe, with the holding screw location, two ends connect with the front and back column with hinge between the two.

In this programme, front column in its parallelogram lindage motion rod member and rear column by about the rod member of two symmetrical bendings form, its lower end is cut with scissors mutually with the hinge at two ends, the base left and right sides and is pressed, the upper end is with coaxial hinged with connecting rack.Its rear column extension rod is to hang 12 springs by a spring hanger bracket, and the mutual alignment of the hanger bracket of its spring and the extension rod of rear column part is regulated by leading screw and handwheel.Its road wheel has four, and two wheels in the place ahead have common brake gear, and two wheels at rear have the steering handle.

Adopt this programme can embody following superiority: 1. the basketball stands that should manually fold have adopted the stored energy mechanism of spring, mix up the stress that puts down and stand two some camber of springs, make and to operate rising and falling of whole basketball frame, bring convenience to the user with minimum strength; 2. when parallelogram lindage moves to the position of rise, locked with the location rod member between the column of front and back, make whole backboard can obtain a position accurately, the weight of base is big in addition, and on two front-wheels, be provided with common braking mechanism, therefore when colliding and taking off basket, stable assurance can be arranged; 3. original basket support height is more than 4 meters, and the height after folding is dropped to 2.5 meters, brings convenience for transportation and storage; 4. its simple in structure, low cost of manufacture is convenient to make in batches promote the use of.

Fig. 1 is the manually front view of folding basketball stands of this programme.

Fig. 2 is the side view of Fig. 1.

Fig. 3 is the vertical view of Fig. 1.

Fig. 4 is the enlarged drawing of I part among Fig. 1.

Fig. 5 is the enlarged drawing of II part among Fig. 1.

The embodiment of existing accompanying drawings this programme.Basketball stands that should be manually folding are made up of to the trailing wheel 12 13 core bar 6 in the front column 3 in backboard 1, connecting rack 2, base 8, the parallelogram lindage, rear column 4, the location rod member, sleeve pipe 7, rear column extension rod 9,

hanger bracket

10,12 springs 5 that hang, two front-wheels 11 with common brake that connect with base, the ribbon gymnastics that connects with base.Its base has very big weight, prop and to promote easily with four wheels, utilize brake that it is fixed up, good stability is arranged, two pairs of hinge first line of a couplet at the top edge of base pick out the motion rod member parallelogram lindage of the right and left for folding usefulness, two hinges of the upper end of column are hinged with connecting rack through one before and after the parallelogram lindage, connecting rack is propped up backboard with rod member, the front and back column all is made up of the rod member of two symmetrical bendings, be provided with the location rod member between the column before and after two, after propping basketball stands, core bar and sleeve pipe are fixed with holding screw, can make basketball stands obtain accurate and stable position, 12 springs are housed on the extension rod under rear column under the hinge, prestress when spring is installed is regulated by the handwheel on the spring hanger bracket, one end of spring hangs on the hanger bracket, and the other end hangs on the base.Because the Position Design of rear column below extension rod is proper, is equipped with suitable spring stress again, make and prop and need not cost a lot of money when folding strength, can bring convenience to the user along operating with manpower.Front at base is attached tight with soft leather bag, can guarantee athletic safety.

The preproduction of this programme is through experiment operation proof: it have performance good, easy to operate, The characteristics of simple in structure, low cost of manufacture are suitable for making in batches promoting the use of.
