Description
Technical field
This utility model relates to a kind of sports equipment, specifically a kind of volleyball frame.
Background technology
Volleyball movement is a ball game extensively liked by people, and volleyball court is rectangle, is separated with high net in the middle of court, nets wide 1 meter, long 9.5 meters.During match, both sides respectively account for a side in court, and ball is played many times from the overhead of net by sportsman with hands.
Volleyball frame is for hanging the support of net in volleyball movement, and at present, existing volleyball frame is mainly made up of base and column, and wherein, the height of column is fixing, it is impossible to be adjusted as required, thus brings a lot of inconvenience to use process.
Utility model content
The purpose of this utility model is just to provide a kind of volleyball frame, to solve the problem that the stem height of existing volleyball frame freely can not adjust according to use demand.
This utility model is achieved in that
A kind of volleyball frame, include: base, it is arranged on the ballast box of described base rear portion, and it is arranged on the column of described pan frontward end, described base is vertically to be provided with vertical insertion pipe in the front end of bottom girder plate, described column includes outer tube and the inner tube of scalable connection, and the lower pipe body of described outer tube is plugged in described insertion pipe, and said inner tube is plugged in the upper portion pipe body of described outer tube；It is provided with lead screw gear mechanism in the inside of described outer tube, is provided with operation handle in the outside of described outer tube；Described lead screw gear mechanism includes being connected to the leading screw bottom said inner tube, be set on described leading screw and the first bevel gear of being connected with described threads of lead screw and the second bevel gear being connected with described operation handle and engaging with described first bevel gear, at the pressure bearing that is arranged over of described first bevel gear, described pressure bearing is set on described leading screw.
Outer cover at described outer tube is provided with pipe collar, and described pipe collar set is buckled in the top of described vertical insertion pipe.
Being horizontally disposed with " one " font shank in the lower pipe body of described insertion pipe, offered two axial inserting grooves in the bottom of described outer tube, described inserting groove coordinates with described shank grafting.
It is provided with road wheel at the rear portion of described ballast box.
This utility model, by column is set to outer tube and the inner tube of scalable connection, achieves freely adjusting of stem height by freely stretching of inner tube, meets different use demands.And, the use of lead screw gear mechanism so that the regulation of stem height is more accurate.
This utility model simple in construction, be connected firmly, good stability, and with low cost, practical safe, easy to utilize.

Detailed description of the invention
As it is shown in figure 1, this utility model is mainly made up of parts such as base 1, ballast box 2 and columns 3.
Base 1 includes bottom girder plate and vertical insertion pipe 7, and insertion pipe 7 is vertically set on the front end of the top surface of bottom girder plate, is horizontally disposed with the shank 14 of " one " font in the lower pipe body of insertion pipe 7, and shank 14 is on a diameter line of insertion pipe 7.Being provided with ballast box 2 in the rear end of bottom girder plate, in order to keep the overall stability of ball-collecting rack, ballast box 2 uses fillet design, the most attractive in appearance but also can effectively prevent sport injury.It is provided with two road wheels 15, in order to mobile box and base 1 at the casing rear portion of ballast box 2.
As in figure 2 it is shown, column 3 is arranged in insertion pipe 7, it outer tube 5 including scalable connection and inner tube 4, the lower pipe body of outer tube 5 is plugged in insertion pipe 7, and the lower pipe body of inner tube 4 is plugged in the upper portion pipe body of outer tube 5.The outer tube diameter of outer tube 5 is slightly less than the internal diameter of insertion pipe 7, in order to inserted in insertion pipe 7 by outer tube 5.Its bottom at outer tube 5 offers two axial inserting grooves 13, and two inserting grooves 13 are symmetrical about the axis of outer tube 5, and inserting groove 13 coordinates with shank 14 grafting, and the body outer cover at outer tube 5 is provided with the pipe collar 8 for buckle insertion pipe 7.After being inserted by outer tube 5 in insertion pipe 7, shank 14 inserts in inserting groove 13, and pipe collar 8 is buckled in the top of insertion pipe 7, thus is greatly improved column 3 and the bonding strength of insertion pipe 7 and stability.
As in figure 2 it is shown, be provided with the lead screw gear mechanism for regulating inner tube 4 lifting in the inside of outer tube 5, this mechanism includes leading screw the 9, first bevel gear 10 and the second bevel gear 11.Leading screw 9 is arranged along the axis of outer tube 5, its top is fixing with the bottom of inner tube 4 to be connected, first bevel gear 10 is set on leading screw 9, and threaded with leading screw 9, it is arranged over pressure bearing 12 at the first bevel gear 10, pressure bearing 12 is set on leading screw 9, moves upward for limiting the first bevel gear 10.Second bevel gear 11 is vertically arranged in the lower section of the first bevel gear 10, and engages with the first bevel gear 10, and the axis of the first bevel gear 10 is mutually perpendicular to the axis of the second bevel gear 11.Be provided with operation handle 6 in the outside of outer tube 5, operation handle 6 is connected with the second bevel gear 11.Rotate forward operation handle 6, the second bevel gear 11 concomitant rotation, and drive the first bevel gear 10 to rotate by gear engagement, and then promote leading screw 9 to move upward, thus realize the rising of inner tube 4.Rotate backward operation handle 6, then inner tube 4 declines.
