Abstract
The utility model discloses a main shaft device, in particular to a spring shaft device used on a rolling shutter door and a window; the device includes a hollow main shaft (8) and is characterized in that the main shaft (8) is sleeved on a fixed shaft (3), a torsion spring (5) is arranged in the inner cavity of the main shaft (8) and one end of the torsion spring is connected with the fixed shaft (3) while the other end is connected with a drive shaft head (7) which is connected with the main shaft (8). Compared with the prior art, the utility model has the advantages of small volume, compact structure, easy installation and low cost.
Description
Technical field:
The utility model relates to a kind of main shaft device, particularly a kind of roll-type window or door spring shaft device.
Background technology:
Roll-type window or door is widely used at present, and rolling slat and main shaft join, and main shaft is installed in the top of door and window.Existing main axle structure has plenty of with power set and joins, and drives its rotation.What also have is equipped with a leaf spring with canoe on main shaft, when the pulling curtain plate is closed the doors and windows downwards, leaf spring produces pretension torsion, when opening roller shutter, the torsion drive shaft of backup plate spring is rotated to make to move on the curtain sheet and is wrapped on the main shaft, and it is big that the leaf spring of this canoe twines the back diameter, and trouble is installed, take than large space, make troubles to integral installation.
Summary of the invention:
The purpose of this utility model provides a kind of roll-type window or door spring shaft device little, compact conformation that takes up room, and overcomes the deficiencies in the prior art.
Technical solution of the present utility model is; A kind of roll-type window or door spring shaft device comprises hollow shape main shaft 8, it is characterized in that: main shaft 8 is sleeved on the fixed axis 3, and torsion spring 5 is positioned at main shaft 8 inner chambers, and an end and fixed axis 3 join, and another termination driving shaft head 7 drives spindle nose 7 and joins with main shaft 8.
Described driving spindle nose 7 is positioned at main shaft 8 inner chambers, and is connected for the polygon socket between the main shaft 8.
The utility model compared with prior art has little, the compact conformation of taking up room, easy for installation, advantage that cost is low.
Description of drawings;
The structural representation of Fig. 1 the utility model specific embodiment;
Fig. 2 is an A-A cross-sectional schematic shown in Figure 1;
Fig. 3 is a D-D sectional schematic diagram shown in Figure 2;
Fig. 4 is that schematic diagram is looked on the right side shown in Figure 1;
Fig. 5 is that schematic diagram is looked on a left side shown in Figure 1.
The specific embodiment:
As shown in the figure: 3 is fixed axis, and the end machining of fixed axis 3 has square hole 9, is connected by the end seat of square hole 9 with side, door and window top.One end of the other end of fixed axis 3 and torsion spring 5 joins, and type of attachment is the termination insertion of torsion spring 5 or hangs tag on fixed axis 3.The other end of torsion spring 5 joins with driving spindle nose 7, and its type of attachment is identical with another termination.Be with axle sleeve 1 in fixed axis 3 outsides, bearing 2 is housed between the two, axle sleeve 1 is rotatable with respect to fixed axis 3.The lateral surface of axle sleeve 1, driving spindle nose 7 is prismatic, and present embodiment is selected form from all directions for use, and the endoporus of main shaft 8 is prismatic, all directions form, and promptly main shaft 8 is interior octagonal steel axle.Main shaft 8 is sleeved on axle sleeve 1, drives on the spindle nose 7.By the cooperation of all directions prismatic surface, main shaft 8 is rotated with axle sleeve 1, driving spindle nose 7.Sleeve 6 is sleeved on outside the torsion spring 5, and two ends and fixed axis 3, driving spindle nose 7 are pegged graft.Core tube 4 is positioned at torsion spring 5 inboards, and two ends and fixed axis 3, driving spindle nose 7 plug and play a supportive role.
When the rolling slat that is connected with main shaft is left behind when closing the doors and windows, main shaft 8 rotates thereupon, and by interior all directions structure drive driving spindle nose 7, axle sleeve 1 rotation, make torsion spring 5 produce pretightning force, when decontroling rolling slat, under the pretightning force effect of torsion spring 5, drive main shaft 8 rotations by driving spindle nose 7, rolling slat is twisted on the main shaft 8, reach the purpose of door and window.
