[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, a small multifunctional vacuum coating equipment includes a vacuum chamber 1 and a hanging rod 2 that is disposed inside the vacuum chamber 1 and inclined in the vertical direction.

[0024] Hook 3 is installed on the hanging rod 2 and is used to limit the rotation of the suspended object;

[0025] The extension rod 4, which is slidably mounted on the rotating hook 3 via a slide groove, extends toward the suspended object as the rotating hook 3 deflects.

[0026] Specifically, during the coating process, the raw material to be coated is suspended on the hanging rod 2. Under gravity, the suspended object slides down the hanging rod 2. When it reaches the position of the rotating hook 3, the suspended object stops sliding and presses against the rotating hook 3 under its own weight, causing the rotating hook 3 to deflect. At this point, the angle between the rotating hook 3 and the hanging rod 2 increases, automatically adapting to the edges of suspended objects of different thicknesses. This avoids the situation where the inner diameter of the rotating hook 3 is too small, making it difficult to hook onto edges of excessively thick suspended objects. As the rotating hook 3 deflects, the area of ​​the hooking part increases, strengthening the hooking effect. Subsequently, the rotating hook 3 drives the extension rod 4 to slide along the groove. The extension rod 4 extends towards the direction of the suspended object, increasing the overall length of the rotating hook 3 and further lengthening the hooking part. The extension rod 4 presses against the surface of the suspended object, restricting its position.

[0027] Furthermore, a hydraulic pump can be installed on the rotating hook 3 and an actuator can be installed on the extension rod 4. When the rotating hook 3 rotates, it compresses the hydraulic pump, which supplies power to the actuator, thereby pushing the extension rod 4 and causing the extension rod 4 to extend as the rotating hook 3 deflects. Alternatively, a trigger switch can be installed on the rotating hook 3, connecting the extension rod 4 to the output end of the electric telescopic rod. When the rotating hook 3 rotates, it compresses the trigger switch, sending a signal to the electric telescopic rod, which then pushes the extension rod 4 to extend. Other transmission structures known to those skilled in the art are also acceptable.

[0028] In the above technology, the suspended object automatically presses against the rotating hook 3, causing the rotating hook 3 to deflect and automatically adapt to the edges of the suspended object of different thicknesses. This avoids the inner diameter of the rotating hook 3 being too small, making it difficult to hook onto the edges of the suspended object that are too thick. Subsequently, the rotating hook 3 drives the extension rod 4 to slide along the groove. The extension rod 4 extends in the direction of the suspended object, which increases the overall length of the rotating hook 3, further lengthens the hooking part, restricts the position of the suspended object, and prevents the suspended object from shaking and becoming unhooked.

[0029] As a further provided embodiment of the utility model, the rotating hook 3 is rotatably arranged at the end of the hanging rod 2, the end of the hanging rod 2 is fixedly provided with a fixed gear 6, and the rotating hook 3 is provided with a movable gear 7 engaged with the fixed gear 6.

[0030] Specifically, the movable gear 7 can be made of elastic plastic material. When the rotating hook 3 is deflected by the suspended object, the movable gear 7 deflects with the rotating hook 3 and rotates relative to the fixed gear 6. Since the fixed gear 6 and the movable gear 7 are engaged, the teeth on the movable gear 7 are pressed by the teeth of the fixed gear 6, and the movable gear 7 is elastic, so that the teeth of the movable gear 7 are slightly deformed and quickly restored, thereby slowing down the deflection speed of the rotating hook 3 as a whole, and playing a damping role.

[0031] As a further provided embodiment of the utility model, the movable gear 7 is rotatably arranged relative to the rotating hook 3, and a plurality of racks 9 engaged with the movable gear 7 are arranged on the extension rod 4.

[0032] Specifically, the movable gear 7 deflects with the rotating hook 3, so that the movable gear 7 rotates as a whole relative to the fixed gear 6. Since the fixed gear 6 is fixedly arranged on the hanging rod 2, and the movable gear 7 is rotatably arranged on the rotating hook 3, the movable gear 7 is driven to rotate by the fixed gear 6, driving the rack 9 and the extension rod 4 to slide along the rotating hook 3, so that the extension rod 4 automatically extends with the deflection of the rotating hook 3, and the extension length is related to the deflection angle of the rotating hook 3, which can automatically adjust the angle and arc length of the hooking part.

[0033] As a further provided embodiment of the utility model, the utility model further comprises a pressing plate 5 arranged on the hanging rod 2, and the pressing plate 5 is provided with an elastic element 10 for maintaining a predetermined angle.

[0034] Specifically, the elastic element 10 has a spiral structure, and the elastic element 10 maintains a predetermined angle between the pressing plate 5 and the hanging rod 2 through the elastic force. When the suspended object slides along the hanging rod 2, the suspended object first presses the pressing plate 5, so that the elastic element 10 is deformed and stores energy. Then, when the suspended object slides to the rotating hook 3, the pressing plate 5 is no longer pressed by the suspended object, and at this time, the elastic potential energy stored in the elastic element 10 is released, driving the pressing plate 5 to return to the predetermined angle. Since the end of the pressing plate 5 is provided with a protrusion 11 for pressing the suspended object, the pressing plate 5 drives the protrusion 11 to press the side of the suspended object during rotation, so that the suspended object is limited.

[0035] As a further provided embodiment of the utility model, the extension rod 4 is provided with a pressing element 8 for locking the pressing plate 5, and the rotating hook 3 has an unlocking station for triggering the pressing plate 5.

[0036] Specifically, the abutting piece 8 is fixedly arranged on the end of the extension rod 4, when the rotating hook 3 is not deflected, the end of the extension rod 4 is close to the end of the hanging rod 2, at this time, the abutting piece 8 is located on the pressing plate 5, so that the pressing plate 5 is locked, and the elastic piece 10 is in a deformed and stored state at this time. When the rotating hook 3 is abutted by the edge of the hanging object, the rotating hook 3 is deflected to the unlocking position, the extension rod 4 extends along the rotating hook 3, so as to drive the abutting piece 8 to move, at this time, the abutting piece 8 is no longer located on the pressing plate 5, so that the abutting piece 8 is staggered with the pressing plate 5, after the pressing plate 5 loses the block, the elastic piece 10 releases the elastic potential energy, the pressing plate 5 is triggered and abuts against the side of the hanging object. After the coating is finished, the hanging object is removed, then the pressing plate 5 is manually close to the hanging rod 2, and then the rotating hook 3 is rotated, so as to drive the extension rod 4 and the abutting piece 8 to recover, until the abutting piece 8 recovers to the default state of being located on the pressing plate 5.

[0037] Working principle: when coating, the raw material to be coated is hung on the hanging rod 2, the hanging object slides along the hanging rod 2 under the action of gravity, when sliding to the position of the rotating hook 3, the hanging object stops sliding and abuts against the rotating hook 3 under the action of gravity, so that the rotating hook 3 is deflected, at this time, the angle between the rotating hook 3 and the hanging rod 2 increases. The movable gear 7 is deflected with the rotating hook 3, so that the movable gear 7 rotates as a whole relative to the fixed gear 6, since the fixed gear 6 is fixedly arranged on the hanging rod 2, and the movable gear 7 is rotatably arranged on the rotating hook 3, the movable gear 7 is driven to rotate by the fixed gear 6, drives the rack 9 and the extension rod 4 to slide along the rotating hook 3, so that the extension rod 4 automatically extends with the deflection of the rotating hook 3, the extension rod 4 extends along the rotating hook 3, so as to drive the abutting piece 8 to move, at this time, the abutting piece 8 is no longer located on the pressing plate 5, so that the abutting piece 8 is staggered with the pressing plate 5, after the pressing plate 5 loses the block, the elastic piece 10 releases the elastic potential energy, the pressing plate 5 is triggered and abuts against the side of the hanging object. After the coating is finished, the hanging object is removed, then the pressing plate 5 is manually close to the hanging rod 2, and then the rotating hook 3 is rotated, so as to drive the extension rod 4 and the abutting piece 8 to recover, until the abutting piece 8 recovers to the default state of being located on the pressing plate 5.

[0038] The above only describes certain exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, the described embodiments can be modified in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and description are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
