Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0030] First embodiment, such as Figure 1-7As shown, the unlocking mechanism of this suspension device can be applied to chandeliers and used for adjusting the height of the chandeliers. Of course, the suspension device can also be used on other ceiling decorations. In this embodiment, the description is based on the connection between the lower end of the suspension line 5 and the chandelier. It includes a main body 4, a suspension line 5 that is wound or released on the main body 4, a ratchet 21 that is rotatably set on the main body 4, and pawls 22 located on the main body 4 that engage with the ratchet 21 and lock it to stop the suspension line 5 from being wound or released, so that the suspension line 5 is kept in a wound or released state and the chandelier is suspended at a certain height. The ratchet 21 has several slots arranged in sequence along the circumference. The pawls 22 engage with different slots to make the chandelier suspend at different height positions, and a sliding device for driving the pawls 22 to disengage from the ratchet 21 to unlock and allow the suspension line 5 to be wound or released.

[0031] The sliding device includes a slider 91, and a transmission structure is provided between the slider 91 and the pawl 22 so that when the slider 91 moves in the forward direction, it can drive the pawl 22 to disengage from the ratchet 21. In this embodiment, Figure 3 Based on this, the sliding member 91 moves to the left for forward operation and to the right for reverse operation. The suspension line 5 extends outward from the main body 4 after being connected to the sliding member 91. The outer end of the suspension line 5 is used to suspend objects. By operating the suspension line 5, a forward force is applied to the sliding member 91, causing the sliding member 91 to move in the forward direction. The sliding member 91 drives the pawl 22 away from the ratchet 21 through the transmission structure and unlocks the ratchet 21. There is no need to use an electric drive form such as an electromagnet. The engagement between the pawl 22 and the ratchet 21 can be disengaged by operating the suspension line 5. The sliding device has the advantages of simple structure and easy operation.

[0032] In some embodiments of this utility model, such as Figure 2-4 As shown, the sliding device includes a reverse drive 92 for driving the slider 91 to move in the opposite direction. One end of the reverse drive 92 is connected to the main body 4, and the other end of the reverse drive 92 is connected to the slider 91. The reverse drive 92 is used to reset the slider 91 after it moves in the forward direction.

[0033] In some embodiments of this utility model, such as Figure 2-4 As shown, the main body 4 is provided with a sliding groove 93, and the sliding member 91 is disposed in the sliding groove 93. The sliding groove 93 is used to guide the operation of the sliding member 91 and improve the stability of the operation of the sliding member 91. The reverse drive member 92 is located in the sliding groove 93 and is located on the side of the sliding groove 93 away from the pawl 22.

[0034] The reverse drive component 92 and the transmission structure are located on both sides of the sliding component 91. The reverse drive component 92 is a spring. The sliding component 91 is provided with a positioning post 911 connected to the reverse drive component 92. The positioning post 911 is used for positioning the reverse drive component 92.

[0035] In some embodiments of this utility model, such as Figure 2-4 As shown, the transmission structure includes a push plate 94 disposed on the sliding member 91 and a transmission rod 95 disposed on the pawl 22. The push plate 94 and the transmission rod 95 are connected in cooperation. Along the trajectory direction of the sliding member 91 in the forward direction, the push plate 94 is located at the rear of the transmission rod 95, so that when the sliding member 91 moves in the forward direction, the push plate 94 pushes the transmission rod 95 to run. The sliding member 91 is provided with a positioning groove 912 for the transmission rod 95 to extend into. The positioning groove 912 extends along the running direction of the sliding member 91. The setting of the positioning groove 912 makes the contact area between the push plate 94 and the transmission rod 95 larger, thereby improving the stability of the cooperation between the push plate 94 and the transmission rod 95.

[0036] In some embodiments of this utility model, such as Figure 2-4 As shown, the pawl 22 is rotatably mounted on the main body 4 via the shaft 96. When the sliding member 91 is running, it drives the pawl 22 to swing around the shaft 96 as the center.

[0037] In some embodiments of this utility model, such as Figure 2-5 As shown, it includes a locking drive 23 for engaging and locking the pawl 22 with the ratchet 21. The locking drive 23 is located on the main body 4. One end of the locking drive 23 is connected to the pawl 22, and the other end of the locking drive 23 is connected to the main body 4. The locking drive 23 is used to drive the pawl 22 to move toward the ratchet 21.

[0038] The locking drive component 23 is an elastic component, and the locking drive component 23 is a spring. The main body 4 is provided with a mounting groove 42 for setting the locking drive component 23. The pawl 22 is provided with a positioning part 221 connected to the locking drive component 23.

[0039] In some embodiments of this utility model, such as Figure 1 , 2 As shown in Figure 4, the sliding member 91 is provided with a mating part 311 that is connected to the suspension line 5 for transmission. The suspension line 5 applies a force to the sliding member 91 through the mating part 311, thereby driving the sliding member 91 to move.

[0040] like Figure 1 , 2 As shown in Figure 4, in this embodiment, the mating part 311 includes a groove provided on the sliding member 91. The suspension line 5 passes through the groove and applies force to the sliding member 91 through the groove. Specifically, when the suspension line 5 is operated to act on the side of the groove, the sliding member 91 moves laterally.

[0041] Alternatively, the mating part 311 may include a protrusion (not shown in the figure) provided on the slider 91. The suspension wire 5 passes around the protrusion and applies force to the slider 91 through the protrusion. The protrusion may be provided on one side of the slider 91. Operating the suspension wire 5 to make the suspension wire 5 act on the protrusion can also drive the slider 91 to run.

[0042] In some embodiments of this utility model, such as Figure 1 , 4 As shown in Figure 5, the device includes a winding and unwinding device 1 located on the main body 4. The inner end of the hanging line 5 is set on the winding and unwinding device 1. The winding and unwinding device 1 is used for winding and unwinding the hanging line 5. By adjusting the winding and unwinding of the hanging line 5, the height of the chandelier can be adjusted. The ratchet 21 is connected to the winding and unwinding device 1 and runs synchronously with the winding and unwinding device 1.

[0043] The take-up and unwinding device 1 includes a spool 11 and an elastic take-up drive 12. The spool 11 is rotatably mounted on the main body 4. The suspension line 5 is wound around the spool 11. The inner end of the suspension line 5 is mounted on the spool 11, and the outer end of the suspension line 5 extends outward from the main body 4. When the spool 11 rotates, it can realize the winding or unwinding of the suspension line 5. The ratchet 21 is fixedly connected to the spool 11. The main body 4 is provided with a shaft 41, which is used for the rotation positioning of the spool 11. The spool 11 is rotatably mounted on the shaft 41. The elastic take-up drive 12 is connected at one end to the spool 11 and at the other end to the shaft 41. The elastic take-up drive 12 is a coil spring. When the pawl 22 is not locked to the ratchet 21 or the take-up and unwinding device 1, the suspension line 5 is wound onto the spool 11 under the action of the elastic take-up drive 12.

[0044] like Figure 1 , 4 As shown, the winding drum 11 is provided with a winding groove 111 for winding the suspension wire 5 and a winding groove 112 for setting the elastic winding drive drum 12. The winding groove 111 and the winding groove 112 are arranged sequentially along the axial direction of the winding drum 11. The winding groove 111 is located in front of or behind the winding groove 112. In this embodiment, the winding groove 111 is located in front of the winding groove 112.

[0045] In some embodiments of this utility model, such as Figure 1 , 4 As shown in Figures 6 and 6, it includes a power connection device 6;

[0046] The power connection device 6 is used to connect to an external power source. The suspension wire 5 contains wires. When the suspension wire 5 is connected to the chandelier, it can supply power to the chandelier through the wires it contains. The suspension wire 5 has both suspension and power transmission functions. The power connection device 6 is electrically connected to the suspension wire 5. The power connection device 6 is set on the main body 4. The power connection device 6 and the ratchet 21 are located on both sides of the retractable device 1. In this embodiment, the power connection device 6 is located on the rear side of the retractable device 1, and the ratchet 21 is located on the front side of the retractable device 1.

[0047] The power connection device 6 includes a movable power connection component 61 mounted on the winding drum 11 and a stationary power connection component 62 located on the main body 4 and electrically connected to the movable power connection component 61. The winding drum 11 has a channel 113 connecting the winding groove 111 and the movable power connection component 61. A limiting plate 114 is provided between the channel 113 and the movable power connection component 61. The limiting plate 114 abuts against the outside of the winding groove 111. The suspension wire 5 is partially mounted on the limiting plate 114. The setting prevents the suspension wire 5 from detaching from the drum 11. The movable connection 61 is set to operate synchronously with the drum 11. The stationary connection 62 is connected to an external electrical component for connecting to a power source. The external electrical component is exposed on the main body 4. The inner end of the suspension wire 5 is electrically connected to the movable connection 61. When the suspension wire 5 is wound or released, the inner end of the suspension wire 5 and the movable connection 61 rotate synchronously with the drum 11. In this embodiment, the external electrical component is an outwardly extending wire to facilitate external power supply.

[0048] There are two sets of moving contacts 61, which are arranged coaxially at intervals and are in a ring shape. There are also two sets of stationary contacts 62, which are connected to the two sets of moving contacts 61 respectively. The two sets of moving contacts 61 and stationary contacts 62 correspond to the positive and negative poles respectively. As those skilled in the art will understand, the ring-shaped moving contacts 61 are designed to ensure that the moving contacts 61 and stationary contacts 62 can maintain an electrical connection when the winding drum 11 is rotating.

[0049] In some embodiments of this utility model, such as Figure 1 , 2 As shown in Figures 3 and 5, the main body 4 is provided with a through hole 46 for the extension of the suspension wire 5, the sliding member 91 is arranged opposite to the through hole 46, and the sliding groove 93 is connected to the through hole 46.

[0050] The main body 4 is positioned upright so that the perforation 46 faces downward and is opposite to the horizontal plane, and the suspension line 5 is led out after passing through the perforation 46;

[0051] The main body 4 includes a base 43, a front cover 44 and a rear cover 45 disposed at the front and rear of the base 43, respectively. The base 43, the front cover 44 and the rear cover 45 form an assembly cavity. The assembly cavity is used for the mounting and dismounting device 1, the ratchet 21 and the pawl 22, the sliding device and the power connection device 6. The through hole 46 is disposed in the base 43, the scroll 41 is disposed on the rear cover 45, and the static power connection device 62 is disposed on the rear cover 45. In the upright state of the main body 4, the through hole 46 is located at the bottom of the main body 4, the sliding member 91 is located below the mounting and dismounting device 1 and the ratchet 21, the pawl 22 is located on one side of the ratchet 21, and the sliding member 91 is located on one side of the pawl 22. In this embodiment, the sliding member 91 is located on the lower side of the pawl 22, and the sliding groove 93 extends laterally.

[0052] The ratchet 21 is provided with an operating part 211 exposed to the main body 4 for rotating and adjusting the ratchet 21. In this embodiment, the operating part 211 is a hexagonal groove. The operating part 211 can be adjusted by using a hexagonal wrench. The winding degree of the suspension line 5 can be adjusted by rotating the operating part 211.

[0053] by Figure 3 Based on the four positions of the main body, the winding and unwinding device 1 rotates counterclockwise to release the rope 5, and rotates clockwise to wind up. Of course, it can also be adjusted to the opposite setting according to actual requirements.

[0054] Second embodiment, such as Figure 5 As shown, the difference from the first embodiment is that the unlocking mechanism of this suspension device has the main body 4 placed on its side so that the through hole 46 is opposite to the vertical surface perpendicular to the horizontal plane. The vertical direction of the main body 4 when it is upright is the height direction of the main body 4. The main body 4 is generally set so that the height dimension is greater than the length dimension and the width dimension. The chandelier is equipped with a top cover 9 for covering this suspension device. The top cover 9 is installed with the ceiling or top wall. The suspension device is located between the top cover 9 and the ceiling or top wall. The suspension wire 5 of the suspension device extends downward from the top cover 9. The side placement of the main body 4 can reduce the vertical space occupied by the suspension device, which is conducive to reducing the thickness of the top cover 9, making the top cover 9 more beautiful and adapting to the case of the top cover 9 being thin. The front side, rear side, left side, or right side of the main body 4 is set downward. The main body 4 can be side-mounted with each side facing downward. The length and width dimensions of the main body 4 are generally different. By setting different sides facing downward, the vertical space occupied by the main body 4 when it is side-mounted is different.

[0055] In some embodiments of this utility model, such as Figure 8 As shown, a wheel set 7 is rotatably mounted on the main body 4 for changing the output direction of the suspension line 5. At the same time, the wheel set 7 serves as the fulcrum of the suspension line 5, facilitating the release and rewinding of the suspension line 5. The main body 4 is provided with a bracket for mounting the wheel set 7, and the wheel set 7 is located on the outside of the main body 4.

[0056] like Figure 9 As shown, this is the case where three sets of suspension devices are used simultaneously. Some chandeliers have more than two sub-light groups. By connecting two or more sets of suspension devices to two or more sub-light groups respectively, the height of each sub-light group can be adjusted independently to form different height combinations. Of course, this situation can also be adapted when the main body 4 is used upright.

[0057] like Figure 10 As shown, this is the case where three sets of suspension devices are used simultaneously. The suspension lines 5 of the three sets of suspension devices are connected to three different positions of the same chandelier. By adjusting the height of the suspension lines 5 of the multiple sets of suspension devices separately, the height position and tilt angle of a single chandelier can be changed. Of course, this situation can also be adapted when the main body 4 is used upright.

[0058] The other parts not described are the same as in the first embodiment and will not be discussed again.

[0059] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
