Description
Technical field
The utility model relates to a kind of arrestment mechanism of chain, belongs to machinery manufacturing technology field.
Background technology
Chain-sprocket drive mechanism is widely used at mechanical field; But when chain be in not closure state time, when chain and sprocket wheel run to chain end mutually, chain and sprocket wheel are easily separated from each other, thus chain is deviate from completely, cause the object of carrying to lose fixed point, cause carrying object loss of stability, easily accidents caused.This situation especially can occur on window opener.
The window opener of employing chain and chain wheel driving mechanism is simple with its structure, volume is little and extensively favored.Chain type window opener comprises and is positioned at housing and intermeshing chain and sprocket wheel, and the chain shaft bangle gear teeth are stirred and drive chain to advance or retreat, thus controls the open and close of window; Generally, when the terminal of setting is walked in sprocket wheel running, system can send a stop signal makes chain stop at preseting length, but when system signal is malfunctioning, chain will run down always, until chain and sprocket wheel depart from completely, forms and window opener can be caused to collide or to fall etc. dangerous.
Utility model content
The technical problems to be solved in the utility model is, proposes a kind of arrestment mechanism of the chain that can prevent chain and sprocket wheel from mutually departing from for the deficiencies in the prior art.
The utility model for solving the problems of the technologies described above proposed technical scheme is: a kind of arrestment mechanism of chain, comprise chain and engage with chain and the sprocket wheel moved forward and backward for chain drive-belt, the side of described sprocket wheel is provided with gripper shoe, described chain is located between sprocket wheel and gripper shoe, described sprocket wheel is relative with the position of described gripper shoe fixing, the end of described chain is provided with brake component, described brake component is located between adjacent two bearing pins in chain, described brake component comprises screw, setscrew nut and hold-down nut, described setscrew nut is positioned at chain side, described hold-down nut is positioned at chain opposite side, described screw is between adjacent two bearing pins and be spirally connected setscrew nut and hold-down nut, when chain wheel drive chain moves forward and backward to described brake component place, the gear teeth of described sprocket wheel block brake component and by locked for chain between sprocket wheel and gripper shoe.
Being improved to of technique scheme: described setscrew nut is positioned at chain near sprocket wheel side, and described hold-down nut is positioned at chain opposite side.
Being improved to of technique scheme: described setscrew nut and hold-down nut are all in circular platform type.
Being improved to of technique scheme: one end diameter of described setscrew nut and hold-down nut is greater than the distance between adjacent two bearing pins of chain, the other end diameter of described setscrew nut and hold-down nut is less than the distance between adjacent two bearing pins of chain.
Being improved to of technique scheme: described setscrew nut and the less one end of hold-down nut diameter are oppositely arranged in described chain both sides.
The beneficial effects of the utility model are: by arranging brake component between adjacent two bearing pins of chain, sprocket wheel is stopped to remaining in operation during brake component in running, thus prevents chain and sprocket wheel from departing from; Because brake component is dismountable screw and nut structure, can according to the actual requirements brake component be arranged on chain diverse location, thus the position that control sprocket wheel and chain stop; Because setscrew nut and hold-down nut are all in circular platform type, and one end diameter is greater than the distance between adjacent two bearing pins of chain, one end is less than the distance between adjacent two bearing pins of chain, like this setscrew nut and the less one end of hold-down nut diameter are oppositely arranged in described chain both sides, the space between two bearing pins just can be inserted in setscrew nut and hold-down nut one end, the other end is stuck in outside space, makes whole brake component and chain stable connection.

Detailed description of the invention
Below by embodiment, the utility model is specifically described.
Embodiment
As shown in Figure 1, the arrestment mechanism of the chain of the present embodiment, comprises chain 1 and sprocket wheel 2, and brake component 3 is arranged between two adjacent bearing pins of chain 1.
As shown in Figure 2, the arrestment mechanism of the chain of the present embodiment, the side of sprocket wheel 2 is provided with gripper shoe 4, chain 1 is located between sprocket wheel 2 and gripper shoe 4, brake component 3 comprises screw 31, setscrew nut 32 and hold-down nut 33, setscrew nut 32 is positioned at chain 1 near sprocket wheel 2 side, and hold-down nut 33 is positioned at chain 1 opposite side, and screw 31 is between adjacent two bearing pins of chain 1 and be rotatably connected with setscrew nut 31 and hold-down nut 33.Setscrew nut 32 and hold-down nut 33 are all in circular platform type.One end diameter of setscrew nut 32 and hold-down nut 33 is greater than the distance between adjacent two bearing pins of chain 1, and other end diameter is less than the distance between adjacent two bearing pins of chain 1.Setscrew nut 32 and the less one end of hold-down nut 33 diameter are oppositely arranged in chain 1 both sides.
First setscrew nut 32 and the less one end of hold-down nut 33 diameter are inserted the space between adjacent two bearing pins from chain 1 both sides respectively during the present embodiment application, then screw 31 is screwed in from setscrew nut 32 side, thus setscrew nut 32 and hold-down nut 33 are linked together.
As shown in Figure 3 and Figure 4, setscrew nut 32 and the less one end of hold-down nut 33 diameter are oppositely arranged in described chain 1 both sides by the arrestment mechanism of the chain of the present embodiment, the space between two bearing pins just can be inserted in setscrew nut 32 and hold-down nut 33 one end, the other end is stuck in outside space, makes whole brake component 3 and chain 1 stable connection.
The present embodiment is when sprocket wheel 2 chain drive-belt 1 moves forward and backward to brake component 3 place, and the gear teeth of sprocket wheel 2 block brake component 3, and under the acting in conjunction of gripper shoe 4 by locked for chain 1 between sprocket wheel 2 and gripper shoe 4.
The arrestment mechanism of a kind of chain of the present utility model is not limited to above-described embodiment.All employings are equal to the technical scheme of replacing and being formed, and all drop in the protection domain of the utility model requirement.
