Abstract
The utility model provides a curtain pulley, which includes a bracket and pulley fixing blocks mounted on the bracket, wherein rollers in even number are mounted on the pulley fixing blocks and distributed on the two sides of the pulley fixing blocks; and clamping grooves used for clamping a synchronous belt are formed in the side surfaces of the pulley fixing blocks. In the curtain pulley provided by the utility model, the rollers in even number are mounted on the pulley fixing blocks and change the original sliding friction into the present rolling friction, so that the resistance is small and the noise is low; meanwhile, the two arranged pulley fixing blocks have the balance function and prevent the pulley from inclining due to non-uniform stress and further avoid affecting the operation; the clamping grooves are formed in the side surfaces of the pulley fixing blocks, and the mounting of the synchronous belt is facilitated through only clamping the synchronous belt in the grooves; and buckles are arranged on the clamping grooves to prevent the synchronous belt from sliding out of the clamping grooves, thereby improving the stability of the curtain pulley.
Description
Technical field
The utility model relates to a kind of electrically driven curtain, particularly a kind of curtain coaster.
Background technology
Raising day by day along with people's living standard, variation has occured in people's house idea, the well-lighted large-scale window of pursuing that beautiful environment, and French window is to a kind of comfortable enjoyment of people, traditional pull curtain and can not satisfy the real requirement of large floor window, waste time and energy when pulling, very inconvenient.Therefore the large floor curtain is equipped with electrically driven curtain usually, realizes the opening and closing of curtain by motor, and is time saving and energy saving, solved large-scale curtain and pulled inconvenient problem.But the coaster that present electrically driven curtain uses has a lot of deficiencies: realize sliding by sliding friction, although simple in structure, cost is lower, but sliding friction is because frictional force is larger, have some setbacks when pulling, noise is excessive, and easily causes wearing and tearing after long-time the use; Traditional coaster is what trouble when Timing Belt is installed, and easily landing from the coaster of Timing Belt, causes Timing Belt can't drive the phenomenon of coaster; Existing Timing Belt is offered promise and is done a hole when mounted on Timing Belt, in its card as supratrochlear card article, it is very inconvenient to install.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model is to provide a kind of Timing Belt and installs simple, firm and the low curtain coaster of the little noise of resistance when pulling.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of curtain coaster, comprise support 4 and the coaster fixed block 2 that is arranged on described support 4, on described coaster fixed block 2, even number roller 1 is installed, described even number roller 1 is distributed in described coaster fixed block 2 both sides, and described coaster fixed block 2 sides are provided with the draw-in groove 61 of establishing Timing Belt for card.
Further, two described coaster fixed blocks 2 are installed on described support 4.
On further described draw-in groove 61, cover has the buckle 5 that can prevent that Timing Belt from skidding off.
Further described draw-in groove 61 sidewalls are provided with the strip projected parts 62 that coordinates with described Timing Belt.
(3) beneficial effect
The utility model curtain coaster is provided with the even number roller on the coaster fixed block, become present rolling friction by original sliding friction, and resistance is little, and noise is low; Pulley fixing frame is two simultaneously, can prevent coaster because unbalance stress causes inclination to balanced action, the impact operation; Be provided with draw-in groove in coaster fixed block side, facilitate Timing Belt to install, only need Timing Belt is snapped in to get final product; Be provided with buckle on draw-in groove, can prevent that Timing Belt from skidding off from draw-in groove, improved its stability.
Description of drawings
Fig. 1 is the structural representation of the utility model curtain coaster;
Fig. 2 is the structural representation of another angle of the utility model curtain coaster;
The structural representation of the coaster fixed block of Fig. 3 the utility model curtain coaster;
The structural representation of the buckle of Fig. 4 the utility model curtain coaster.
The specific embodiment
Consult Fig. 1 ~ Fig. 4, the utility model provides a kind of curtain coaster, comprise support 4 and the coaster fixed block 2 that is arranged on this support 4, even number roller 1 is installed on coaster fixed block 2, be generally 2, and this even number roller 1 is distributed in coaster fixed block 2 both sides, and coaster fixed block 2 sides are provided with the draw-in groove 61 of establishing Timing Belt for card; In order to improve the overall stability of coaster, two coaster fixed blocks 2 are installed on support 4; In order to prevent that Timing Belt from skidding off from draw-in groove, cover has buckle 5 on draw-in groove 61, after installing Timing Belt, buckle 5 is buckled is got final product, and is very convenient; Be provided with the strip projected parts 62 that coordinates with Timing Belt at draw-in groove 61 sidewalls, when Timing Belt is installed, the groove on Timing Belt is aimed at these strip projected parts 62 insertions get final product, this strip projected parts can prevent that Timing Belt from skidding.In the utility model, support 4 is metal structure, and it has been connected by screw brace 3, and this brace 3 is plastics, and it is fastened on coaster fixed block 2.The utility model curtain coaster is provided with the even number roller on the coaster fixed block, become present rolling friction by original sliding friction, and resistance is little, and noise is low; Pulley fixing frame is two simultaneously, can prevent coaster because unbalance stress causes inclination to balanced action, the impact operation; Be provided with draw-in groove in coaster fixed block side, facilitate Timing Belt to install, only need Timing Belt is snapped in to get final product; Be provided with buckle on draw-in groove, can prevent that Timing Belt from skidding off from draw-in groove, improved its stability.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
