Specifically, the tilted door panels are manually moved onto a trolley before being transported. The entire process is time-consuming, labor-intensive, and inefficient. In addition, it is not easy to hold the tilted door panels firmly when manually moving them, which can easily lead to slippage and safety accidents.

[0003] Chinese patent CN215706435U discloses a trolley for transporting electrical cabinets. The design features a movable frame on the trolley that is driven by a drive device. The movable frame can be rotated to easily support the electrical cabinet and keep it in an upright position. However, the movable frame in this design cannot be adjusted in width according to the size of different door panels, resulting in limited clamping and fixing effect.

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See Figures 1-6 This utility model provides a technical solution:

[0028] like Figure 1-6 As shown, a manual clamping mechanism is located at the front end of a transfer trolley 9, including a horizontal bar 1, a vertical bar 2, an adjusting bar 4, and claws 3. The vertical bar 2 is fixed below the middle of the horizontal bar 1 and is connected to the pitching mechanism of the transfer trolley 9. Two sets of claws 3 are located on both sides of the horizontal bar 1, and the claws 3 are slidably connected to the horizontal bar 1 through a guide rail slider assembly 5. The two ends of the horizontal bar 1 are provided with wire wheels 6, and an annular first wire rope 61 is provided between the two wire wheels 6. The two sets of claws 3 are respectively fixed to the upper and lower layers of the annular first wire rope 61, and the two sets of claws 3 move towards or in opposite directions through the first wire rope 61 and the wire wheels 6.

[0029] The upper end of the adjusting rod 4 is located inside the vertical rod 2, and the bottom end of the adjusting rod 4 is provided with a support plate 41. The vertical rod 2 is provided with a guide wheel 21 above the adjusting rod 4. A second steel wire rope 8 is provided between the claw 3 on one side and the adjusting rod 4. The second steel wire rope 8 passes around the guide wheel 21 and connects to the top of the adjusting rod 4.

[0030] Through the above technical solutions, such as Figure 5 As shown, the door panels 10 are stacked at an angle. The manual clamping mechanism is moved to the front of the door panels 10 by the transfer trolley 9. Since the bottom of the door panels 10 will tilt upwards, the manual clamping mechanism is tilted by the pitching mechanism of the transfer trolley 9, so that the support plate 41 of the clamping mechanism of the door panels 10 moves to the underside of the tilted part of the door panels 10. At this time, the claws 3 open and are located on both sides of the door panels 10.

[0031] Then move one side of the claw 3 closer to the door leaf 10. Since the two sets of claws 3 are connected to the upper and lower layers of the first ring-shaped steel wire rope 61 respectively, the two sets of claws 3 move towards each other along the guide rail slider assembly 5 under the action of the first steel wire rope 61 and the steel wire wheel 6. At this time, the claws on both sides can be moved closer to each other by moving one side of the claw 3 to clamp the door leaf 10.

[0032] Then as Figure 6 As shown, the manual clamping mechanism is adjusted by the pitch mechanism. At this time, the door leaf 10 is vertical. Under the weight of the door leaf 10, the support plate 41 drives the adjusting rod 4 to move downward. At this time, the second steel wire rope 8 will drive the connected claw 3 to move towards the middle. Under the action of the first steel wire rope 61 and the steel wire wheel 6, the two sets of claws 3 can move closer and clamp synchronously. The clamping and fixing are completed by the weight of the door leaf 10.

[0033] The entire manual clamping mechanism has a simple structure and is easy to operate. It can quickly clamp the door leaf 10 and improve the clamping effect by relying on the weight of the door leaf 10 itself. At the same time, the claw 3 can adapt to door leaves 10 of different widths, thus increasing the clamping range.

[0034] Furthermore, the adjusting rod 4 is provided with a ratchet 7, the tooth surface of the ratchet 7 is inclined upward, the adjusting rod 4 is provided with a first slot 42 corresponding to the tooth surface of the ratchet 7, the vertical rod 2 is provided with a second slot 23 corresponding to the first slot 42, a buckle 24 is provided outside the second slot 23, the two sides of the buckle 24 are hinged to the vertical rod 2, and one end of the buckle 24 extends into the first slot 42 and the second slot 23 to engage with the ratchet 7.

[0035] With the above technical solution, when the door leaf 10 falls onto the support plate 41, the weight of the door leaf 10 causes the support plate 41 and the adjusting rod 4 to move downwards. Since the tooth surface of the ratchet 7 is inclined downwards, the ratchet 7 can move downwards, and the latch 24 will not lock with the ratchet 7. Until the claws 3 on both sides of the door leaf 10 clamp the door leaf 10, the friction between the claws 3 and the side wall of the door leaf 10 is balanced by the weight of the door leaf 10, and the door leaf 10 and the adjusting rod 4 no longer slide down.

[0036] Before the manual clamping mechanism clamps, the latch 24 needs to be pulled upwards to disengage it from the ratchet 7. Then, one side of the claw 3 is pulled open. At this time, under the action of the first wire rope 61 and the wire wheel 6, the claws 3 on both sides move away from each other. The two claws 3 are pulled open to facilitate clamping door panels 10 of different widths. Since the adjusting rod 4 is connected to the claw 3 through the second wire rope 8, when the claw 3 is pulled open, the adjusting rod 4 retracts inwards towards the vertical rod 2, and the support plate 41 retracts towards the vertical rod 2. At the same time, after stopping the claw 3 from being pulled open, the latch 24 is released, and the latch 24 and the ratchet 7 are locked. At this time, the position of the adjusting rod 4 remains unchanged to prevent the claw 3 from moving.

[0037] Furthermore, a connecting rod 43 is provided below the ratchet 7 of the adjusting rod 4. Both ends of the connecting rod 43 extend through the adjusting rod 4 and out of the vertical rod 2. The vertical rod 2 is provided with a strip groove 25 corresponding to the position of the connecting rod 43. Both ends of the vertical rod 2 are provided with tension springs 44. One end of the tension spring 44 is connected to the connecting rod 43, and the other end of the tension spring 44 is fixed to the vertical rod 2.

[0038] Through the above technical solution, the tension spring 44 connects the vertical rod 2 and the internal adjusting rod 4, preventing the adjusting rod 4 from detaching from the vertical rod 2 under its own weight and avoiding the adjusting rod 4 from shaking before clamping the door leaf 10. At the same time, since the vertical rod 2 is provided with a strip groove 25, the adjusting rod 4 can be easily adjusted up and down.

[0039] Furthermore, the claw 3 has an L-shaped structure, and the door leaf 10 is located between the support plate 41 and the claw 3.

[0040] Through the above technical solution, the L-shaped structure of the claw 3 makes it easy to clamp the door leaf 10. At the same time, the end of the L-shaped claw 3 is provided with teeth to improve the friction between the claw 3 and the side of the door leaf 10.

[0041] Furthermore, the two sets of guide rail slider assemblies 5 are respectively arranged on the top and back surfaces of the crossbar 1.

[0042] Through the above technical solution, the guide rail slider assembly 5 includes a guide rail and a slider. The guide rail is fixed on the crossbar 1, and the slider is connected to the jaw 3. The guide rail slider assembly 5 enables the jaw 3 to slide against the crossbar 1. Simultaneously providing two sets of guide rail slider assemblies 5 can improve the support effect on the jaw 3.

[0043] Furthermore, the first wire rope 61 is fixed to the claw 3 by the pressure plate 62.

[0044] With the above technical solution, the first wire rope 61 surrounds two sets of wire wheels 6, and the claws 3 on both sides are fixed to the wire rope by pressure plates 62 respectively. The two pressure plates 62 are arranged in a centrally symmetrical manner. When the first wire rope 61 moves in a ring, the two claws 3 can move towards each other or in opposite directions.

[0045] Furthermore, a diagonal brace 22 is provided between the horizontal bar 1 and the vertical bar 2 to improve the connection strength between the horizontal bar 1 and the vertical bar 2.

[0046] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
