Abstract

The utility model discloses a lifting basketball stand, which is composed of a backboard, a lifting truss, a fixed truss and a lifting device. The utility model is characterized in that the lifting truss is glidingly matched with the fixed truss in a double pipe way, and the lifting device is arranged on the central position of the lifting truss and the fixed truss, wherein, the lifting device is composed of a pair of screw rod and screw nut which are matched with each other. The center driving lifting mode can effectively avoid the clamping phenomenon caused by the asynchronous displacement brought by the double-side lifting way, and thereby, the height of the backboard is conveniently adjusted. The utility model has the characteristics of simple structure and reliable displacement.

Description

The lifting basketball stands

The utility model relates to the basketball stands that a kind of sports are used, particularly a kind of basketball stands of regulating the backboard height.

Existing basketball stands are made up of the coupling bar between support, support and the backboard, backboard, and coupling bar is fixed on support and the backboard, make the distance on backboard and ground remain unchanged, and this is very inconvenient for the people of all ages and classes, different heights.Chinese patent CN2160430Y discloses a kind of lifting basketball stands, and being increases anchor ear and clamping plate on existing coupling bar, stays some jacks on the support on both sides, with screw anchor ear is stuck on the support, utilizes latch to fix, but the height of up-down adjustment backboard.The mode that this bilateral is regulated the double base member height is very original, is subjected to restriction and because the deviation or the asynchronous stuck phenomenon that easily causes of displacement of both sides jack position of jack distance.

The purpose of this utility model provides a kind of lowering or hoisting gear of single type of drive, can realize the random lifting of double base member and can not cause stuck phenomenon, and have simple in structure, convenience operation.

Technical solution of the present utility model is such: the upper end of lifting truss 2 and backboard 1 are fixing, the lower end column is enclosed within the telescopic guide rail 7 of fixing truss 3, fixedly the top of truss 3 is telescopic columns 7, which is provided with two exchange lock screw 8, lifting truss 2 can be locked on the optional position of fixing truss 3; Lowering or hoisting gear is made up of the screw rod 4 and the nut 5 of a pair of mutual coupling, the upper end of screw rod 4 be fixed on the locational nut 5 of lifting truss 2 crossbeam central shaft holes and be connected, the axis hole that fixing truss 3 crossbeam centers are passed in the lower end of screw rod 4 with shake handle or drive motors 6 is connected.

The technical program is because lowering or hoisting gear is positioned at the lifting truss and the fixing center of truss, shake handle or drive motors and just can regulate lifting truss and the fixing relative position between the truss easily, the asynchronous stuck phenomenon that causes of displacement that this single up-down mode that drives can avoid the bilateral lifting to be brought, thus the height of backboard regulated easily.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Figure one is a back of the present utility model cutaway view.

Figure two is side views of the present utility model.

Figure three is partial schematic diagrams of the present utility model.

Figure four is schematic diagrames of the utility model lifting truss.

Figure five is fixedly schematic diagrames of truss of the utility model.

Among the figure one, fixedly ground is fixed in the lower end of truss 3, the guide tracked sleeve 7 of upper end is slidingly matched with the column of lifting truss 2 lower ends, lowering or hoisting gear comprises a pair of screw rod that is complementary 4 and nut 5, nut 5 is passed in the upper end of screw rod 4, nut 5 is fixed on the crossbeam center of lifting truss 2, the lower end of screw rod 4 pass on the fixed cross beam central shaft hole with shake handle 6 and be connected.Handle 6 is shaken in driving, drives screw rod 4 rotations, and nut 5 promptly moves up and down, make lifting truss 2 and fixedly the distance between the truss 3 change, the height of backboard is also done corresponding change.After being adjusted to desired height, for safety, reliable for the purpose of, available lock screw 8 fixedly lifting truss 2 and the fixing relative position between the truss 3 that is located on the fixing truss 3 telescopic columns, then backboard remains on certain altitude.
