Abstract
The utility model discloses a sling support frame which comprises two vertically arranged wall racks and a transverse beam which is erected on the two wall racks and can rotate relative to the wall racks, wherein self-lubricating bushes are arranged between supporting parts at two ends of the transverse beam and supporting holes in the corresponding wall racks. The self-lubricating bushes have the self-lubricating function, and the friction coefficient is low, so that the transverse beam is flexible to rotate, and the wear of the wall racks is reduced.
Description
Technical field
The utility model relates to a kind of suspender bracing frame.
Background technology
The suspender bracing frame is the device that supports suspension hook in the weight-lifting equipment, suspender bracing frame of the prior art generally comprise two ledges that vertically arrange and pass these two ledges and with the crossbeam of ledge normal-running fit.Because crossbeam of the prior art directly contacts with ledge, the cliding friction between crossbeam and the ledge is dry friction, and friction drag is large, therefore can cause crossbeam to rotate the problems such as dumb and ledge serious wear.
Summary of the invention
The purpose of this utility model is to provide a kind of suspender bracing frame, and the crossbeam of this suspender bracing frame and ledge friction drag are little, and crossbeam rotates flexibly, the ledge wearing and tearing reduce thereby make.
For achieving the above object, the utility model adopts following technical scheme: the suspender bracing frame, be provided with self-lubricating bushing between the supported hole on the crossbeam that also can rotate relative to ledge on comprising two ledges that vertically arrange and being erected at these two ledges, the support portion at described crossbeam two ends and corresponding ledge.
Described lining fixedly is assemblied on the ledge, described crossbeam and described lining trepanning face normal-running fit.
One end of described lining has the outer rim of a circle radial protrusion, and described ledge supported hole one end is provided with the counterbore that cooperates with described outer rim, and described lining fixedly is assemblied on the ledge by the screw that is connected on the lining outer rim.
The utility model is provided with self-lubricating bushing between ledge and crossbeam, because self-lubricating bushing has self-lubricating function, friction coefficient is little, therefore makes crossbeam rotate flexibly and reduce the wearing and tearing of ledge.
Further, the outer rim that an end of lining is provided with projection is convenient to lining and fixedly is assemblied on the ledge, and screw is fixed on the ledge lining failure-free.
Description of drawings
Fig. 1 is the scheme drawing of a kind of embodiment of the utility model;
Fig. 2 is the A-A view among Fig. 1;
Fig. 3 is the partial enlarged drawing of self-lubricating bushing and ledge connecting bridge among Fig. 1.
The specific embodiment
The embodiment of the utility model suspender bracing frame as shown in Figure 1-Figure 3, it comprises two ledges 1 that vertically arrange, be erected on two ledges 1 and with the crossbeam 5 of ledge 1 normal-running fit, be provided with self-lubricating bushing 2 between the supported hole on the support portion at crossbeam 5 two ends and the corresponding ledge 1, lining 2 fixedly is assemblied on the ledge 1, crossbeam 5 and lining 2 trepanning face normal-running fiies, one end of lining 2 has the outer rim of a circle radial protrusion, ledge 1 supported hole one end is provided with the counterbore that cooperates with described outer rim, described lining 2 fixedly is assemblied on the ledge 1 by the screw 4 that is connected on lining 2 outer rims, is provided with packing ring 3 between screw 4 and lining 2.
The suspender bracing frame of present embodiment can be at the fixing device such as suspension hook of crossbeam 5, and crossbeam 5 is by self-lubricating bushing 2 and ledge 1 normal-running fit, because the friction coefficient of self-lubricating bushing is little, has therefore reduced the wearing and tearing of ledge 1 and crossbeam 5 is rotated sensitive; The peripheral edge portion of lining 2 projections cooperates with the counterbore of ledge supported hole one end, makes lining 2 and 1 stable cooperation of ledge, by screw 4 lining 2 and ledge 1 is connected into integral structure, and the lining failure-free is fixed on the ledge.
In other embodiment of the present utility model, self-lubricating bushing can fixedly not be assemblied on the ledge yet, and with the support portion that is fixed on the crossbeam two ends, at this moment be normal-running fit between lining and the ledge, friction therebetween is cliding friction.
Suspender bracing frame of the present utility model also can be used in other technical field with crossbeam and ledge structure.
