Individual inside groove, the groove is embedded with corresponding ball, and the ball is fitted close with the groove.
Above-mentioned constant-force spring hanger, wherein, the protective case is processed by silicon rubber.
The utility model can realize following beneficial effect：
Due to being cased with protective case outside the arm-tie, the periphery of protective case is provided with ball, when arm-tie is moved, and end plate is drawn with described
The contact surface of plate contacts for point, reduces frictional force between the two, it is to avoid the abrasion between arm-tie and end plate, so that, greatly
Frictional force of the present utility model is reduced greatly, and the utility model is simple in construction；Further, since provided with elasticity branch in protective case
Frame, makes protective case have preferable retractility, makes have certain surplus between arm-tie and end plate, can compensate for arm-tie or end plate is long
The margin of error after time use, so that, improve the constancy of suspension and support.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model protective case.
Fig. 3 is the structural representation of the utility model end plate.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As illustrated, in order to solve the above-mentioned technical problem, a kind of constant-force spring hanger of the utility model, including housing
10th, revolution deckle board 6, exterior deckle board 8, revolution deckle board 6 are spindle rotationally arranged on exterior deckle board 8 by gyroaxis 7, the revolution deckle board
It is arranged in one end of the housing, housing 10 and is provided with spring 1, arm-tie 5 and pull bar 3, the revolution deckle board connects with the housing
Meet place and be provided with end plate 20；The pull bar 3 is connected with arm-tie 5 by fastener, and arm-tie passes through the end plate 20, with revolution deckle board 6
Connection, one end of pull bar 3 is fixed with pressing plate 2 by fastener or other modes, and spring 1 is enclosed on outside pull bar 3 and arm-tie 5, and bullet
The two ends of spring 1 are against on platen 2 and end plate 20 respectively, and the outer peripheral face of the arm-tie 5 is provided with protective case 50, and the protective case is located at
The junction of the arm-tie and the end plate, the protective case is cylindrical center component, and the protective case perisporium is provided with cavity
