Abstract
The utility model discloses an automatic scrolling device which comprises a mandrel and a coiled spring, wherein the coiled spring is arranged in a spring box; a viscous damping stick is arranged between the mandrel and the coiled spring; one end of the viscous damping stick is fixed on the spring box; and the other end of the viscous damping stick is fixed on the mandrel. After the viscous damping stick is adopted, the speed for pulling down or rewinding a roller blind is slow and gentle; so that in this way, the roller blind can work more stably, and the device improves the using effect and the service life.
Description
Technical field
The utility model relates to the reel device that a kind of television set is decorated the picture curtain on the picture frame, specifically is a kind of picture curtain spool of gentle backrush problem slowly that solves.
Background technology
At present, common automatic reel in the daily life, decorate the picture curtain of picture frame as television set, when the picture curtain is pulled down to the bottom, during the slip return unit, draw curtain under the active force of wind spring fast backrush realize the function of automatic curtain, this moment since without any restriction, big injury television set easily of the impulse force of wind spring backrush and picture curtain self will influence whole result of use and service life like this.
The utility model content
The too big problem of impulse force when the purpose of this utility model has been to provide a kind of automatic reel device to solve the spool backrush, by the following technical solutions: a kind of automatic reel device, described automatic reel device comprises mandrel, wind spring and roller shutter pipe, described mandrel is built in the two ends of roller shutter pipe, described wind spring places in the spring box, described spring box is connected an end of mandrel, be provided with a viscous damping rod between described mandrel and the spring box, one end is pegged graft and is fixed on the spring box, and the other end is pegged graft and is fixed on the end face of mandrel.
The two ends of described viscous damping rod are square in order to the part of pegging graft.
After the utility model adopts the viscous damping rod,, make slow and soft that roller shutter speed drop-down or backrush becomes, like this, make and the work that roller shutter can be more stable improved result of use and service life because the viscous damping rod has played inhibition.
Description of drawings
Be described in further detail below in conjunction with the drawings and specific embodiments
Fig. 1. the assembling schematic diagram of spool;
The assembling schematic diagram of Fig. 2, viscous damping rod.
Among the figure 1, bearing 2, wind spring 3, spring box 4, mandrel 5, viscous damping rod 6, roller shutter pipe
The specific embodiment
Assembling schematic diagram of the present utility model as shown in Figure 1, 2, comprise bearing 1, wind spring 2, spring box 3, mandrel 4, viscous damping rod 5, roller shutter pipe 6, wind spring 2 places in the spring box 3, wind spring 2 outer ends and spring box 3 outside bayonet sockets are fixed, wind spring 2 centers are inner fixing with bearing 1, have a square opening on the spring box 3, and mandrel 4 is built in the roller shutter pipe 6, in the mandrel 4 be square opening, and viscous damping rod 5 two ends place respectively in the hole on the spring box 3 in the square opening with mandrel 4.
The course of work: during the pulling roller shutter, owing to be subjected to the effect of viscous damping rod 5, drop-down speed is slow, after being pulled down to the bottom, promptly is fixed.When needing backrush, the slip return unit, wind spring 2 drives spring box 3, mandrel 4 and roller shutter pipe 6 and rotates under the effect of elastic force, draw the rapid backrush of curtain this moment, because 5 inhibitions of middle viscous damping rod, it is slow and soft to make that the speed of roller shutter backrush becomes, and does not so just have bigger backrush impulse force, has improved the stability of working greatly.Certainly the utility model not only is applicable to the picture curtain of the picture frame of television set, relates to the equipment of automatic reel device, all drops into protection domain of the present utility model.
Claims (2)
1. automatic reel device, described automatic reel device comprises mandrel, wind spring and roller shutter pipe, described mandrel is built in the two ends of roller shutter pipe, described wind spring places in the spring box, described spring box is connected an end of mandrel, it is characterized in that: be provided with a viscous damping rod between described mandrel and the spring box, an end is pegged graft and is fixed on the spring box, and the other end is pegged graft and is fixed on the end face of mandrel.
