[0054] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a lifting fixture 100. The lifting fixture 100 includes a box 110, a first fixed shaft 120, an eccentric wheel 130, a connecting shaft 140, an operating rod 150, a second fixed shaft 160, an elastic member 170, a connecting rod 180 and a limiting mechanism 190.

[0055] See also Figure 3 and Figure 4 The box body 110 has a receiving chamber 112 with an opening 111 on one side. A hook portion 113 is provided on one side of the box body 110 close to the opening 111. The hook portion 113 is used to hook the front hanging part 200. The opening 111 is communicated with the receiving chamber 112 and the hook portion 113 respectively. A first fixed shaft 120 is provided on the inner side wall of the box body 110. An eccentric wheel 130 is provided on the first fixed shaft 120 and is rotatably connected to the first fixed shaft 120. A connecting shaft 140 is provided on the eccentric wheel 130 and is spaced apart from the first fixed shaft 120. One end of the operating rod 150 is provided outside the box body 110, and the other end is connected to the eccentric wheel 130 through the connecting shaft 140. The second fixed shaft 160 is arranged on the inner wall of the box body 110 and is spaced apart from the first fixed shaft 120 and the connecting shaft 140 respectively. The elastic member 170 is connected to the connecting shaft 140 and the second fixed shaft 160 respectively. One end of the connecting rod 180 is fixedly connected to the connecting shaft 140.

[0056] Combination Figure 5 As shown, the limiting mechanism 190 is arranged on the inner bottom wall of the box body 110, and includes a limiting member 191 and a movable component 192. The limiting member 191 is provided with a limiting groove 1911, a first slide groove 1912 and a second slide groove 1913. The limiting groove 1911 is respectively connected with the first slide groove 1912 and the second slide groove 1913, and the first slide groove 1912 is connected with the second slide groove 1913. The movable component 192 is slidably connected with the limiting groove 1911, the first slide groove 1912 and the second slide groove 1913, and the end of the connecting rod 180 away from the connecting shaft 140 is hinged to the movable component 192.

[0057] The embodiment of the present application provides a lifting fixture 100, see Figure 7 and Figure 8 When it is necessary to lift the part to be hoisted 200, the staff can turn the operating rod 150 clockwise to drive the connecting shaft 140, the eccentric wheel 130 and the connecting rod 180 to rotate clockwise synchronously, so that under the action of the connecting rod 180, the movable component 192 is driven to slide downward and leave the limiting groove 1911. After the movable component 192 slides downward and leaves the limiting groove 1911, the staff releases the operating rod 150, and under the action of the resetting contraction force of the elastic member 170, the connecting shaft 140, the eccentric wheel 130, the operating rod 150 and the connecting rod 180 can be driven to automatically rotate counterclockwise and drive the movable component 192 to automatically slide upward along the first sliding groove 1912, so that the eccentric wheel 130 passes through the opening 111 and presses the part to be hoisted 200 onto the hook portion 113, effectively improving the hoisting safety. In addition, during lifting, the hoisting component 200 tends to move downward relative to the lifting fixture 100 under the action of its own gravity, so that the eccentric wheel 130 tends to rotate counterclockwise due to the friction contact between the hoisting component 200 and the eccentric wheel 130, thereby further compressing the hoisting component 200 and further improving the lifting safety.

[0058] See also Figure 2 and Figure 6When the lifting is completed and the part to be lifted 200 needs to be removed, the staff can turn the operating lever 150 clockwise to drive the connecting shaft 140, the eccentric wheel 130 and the connecting rod 180 to rotate clockwise synchronously, thereby separating the eccentric wheel 130 from the part to be lifted 200, and then the part to be lifted 200 can be removed. At the same time, under the action of the connecting rod 180, the movable component 192 is driven to slide downward along the second slide groove 1913. When the movable component 192 slides downward along the second slide groove 1913 and approaches the limiting groove 1911, the staff releases the operating rod 150. Under the action of the resetting contraction force of the elastic member 170, the connecting shaft 140, the eccentric wheel 130, the operating rod 150 and the connecting rod 180 can be driven to automatically rotate counterclockwise and drive the movable component 192 to automatically slide upward along the limiting groove 1911 to be stuck in the limiting groove 1911, so that the eccentric wheel 130 and the part to be hoisted 200 are kept in a separated state, thereby facilitating the removal of the part to be hoisted 200. The hoisting fixture 100 provided in the present application can realize the assembly and disassembly of the part to be hoisted 200 by toggling the operating rod 150, which is simple to operate, convenient to assemble and disassemble, and can effectively improve the hoisting safety.

[0059] Exemplarily, the component to be hoisted 200 may be a steel frame, and the elastic component 170 may be a tension spring.

[0060] like Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, in one embodiment of the present application, the movable component 192 includes a first movable part 1921, a second movable part 1922 and a sliding part 1923, the second movable part 1922 is arranged on a side of the first movable part 1921 close to the limiting part 191, the second movable part 1922 is provided with a third sliding groove 19221, one end of the sliding part 1923 is slidingly connected to the limiting groove 1911, the first sliding groove 1912 and the second sliding groove 1913, and the other end is slidingly connected to the third sliding groove 19221, the first movable part 1921 is slidingly connected to the limiting part 191, and the end of the connecting rod 180 away from the connecting shaft 140 is hinged to the first movable part 1921.

[0061] In this embodiment, by hingedly connecting one end of the connecting rod 180 away from the connecting shaft 140 to the first movable member 1921, the first movable member 1921 is slidably connected to the limiting member 191, and the second movable member 1922 is arranged on the side of the first movable member 1921 close to the limiting member 191, the connecting rod 180 can drive the first movable member 1921 and the second movable member 1922 to slide up and down synchronously relative to the limiting member 191. At the same time, by opening the third sliding groove 19221 on the second movable member 1922, one end of the sliding member 1923 is slidingly connected to the limiting groove 1911, the first sliding groove 1912 and the second sliding groove 1913, and the other end of the sliding member 1923 is slidingly connected to the third sliding groove 19221. In this way, when the connecting rod 180 drives the first movable member 1921 and the second movable member 1922 to slide up and down synchronously relative to the limiting member 191, the sliding member 1923 can slide along the third sliding groove 19221, thereby enabling the sliding member 1923 to slide along the limiting groove 1911, the first sliding groove 1912 and the second sliding groove 1913.

[0062] Therefore, see Figure 7 and Figure 8 When it is necessary to lift the part 200 to be hoisted, the staff can toggle the operating rod 150 clockwise to drive the connecting shaft 140, the eccentric wheel 130 and the connecting rod 180 to rotate clockwise synchronously, so that under the action of the connecting rod 180, the movable component 192 is driven to slide downward relative to the limit member 191, so that the sliding member 1923 slides downward from the limit groove 1911. After the sliding member 1923 slides downward from the limit groove 1911, the staff releases the operating rod 150, and under the action of the resetting contraction force of the elastic member 170, the connecting shaft 140, the eccentric wheel 130, the operating rod 150 and the connecting rod 180 can be driven to automatically rotate counterclockwise and drive the sliding member 1923 to automatically slide upward along the first slide groove 1912, so that the eccentric wheel 130 passes through the opening 111 to press the part 200 to be hoisted on the hook portion 113, thereby effectively improving the hoisting safety.

[0063] See also Figure 2 and Figure 6When the lifting is completed and the part to be lifted 200 needs to be removed, the staff can turn the operating lever 150 clockwise to drive the connecting shaft 140, the eccentric wheel 130 and the connecting rod 180 to rotate clockwise synchronously, thereby separating the eccentric wheel 130 from the part to be lifted 200, and then the part to be lifted 200 can be removed. At the same time, under the action of the connecting rod 180, the movable component 192 is driven to slide downward relative to the limit member 191, so that the sliding member 1923 slides downward along the second slide groove 1913. When the sliding member 1923 slides downward along the second slide groove 1913 and approaches the limit groove 1911, the staff releases the operating rod 150. Under the action of the reset contraction force of the elastic member 170, the connecting shaft 140, the eccentric wheel 130, the operating rod 150 and the connecting rod 180 can be driven to automatically rotate counterclockwise and drive the sliding member 1923 to automatically slide upward along the limit groove 1911 to get into the limit groove 1911, so that the eccentric wheel 130 and the hoisting part 200 remain in a separated state, thereby facilitating the removal of the hoisting part 200.
