Description

Technical Field

[0001] This utility model relates to the technical field of waste treatment equipment, specifically to a composite locking device for a combined container unloading door. Background Technology

[0002] Existing integrated container unloading doors mostly employ a rubbing-type locking structure, which locks via a single-sided hook or pin. However, this type of structure has the following drawbacks: Traditional hook-type locking mechanisms utilize leverage to reduce operating torque, but the locking force is concentrated on both sides of the door, causing localized deformation of the sealing strip. Over time, the sealing strip ages due to uneven pressure distribution, easily leading to water leakage or garbage seepage, causing secondary pollution; under vibration or impact conditions, the locking force of the hook structure easily weakens, causing the hook to loosen from the door frame, creating a gap between them, making it difficult to maintain sealing pressure; when the sealing strip wears out, frequent replacement or manual adjustment of the locking position is required, increasing maintenance costs.

[0003] Therefore, it is necessary to provide a composite locking device for the integrated unloading door of the container to solve the above-mentioned technical problems. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to solve the sealing failure problem of the unloading gate in the prior art caused by the single locking force and uneven distribution of sealing pressure, especially the defects such as the easy loosening of the locking mechanism under vibration environment.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: it includes a box body, one end of which is provided with an opening, and a door body is hinged to the upper end of the opening. Symmetrical double-locking hook mechanisms are provided on both sides of the opening. Two protrusions are provided on both sides of the door body. The double-locking hook mechanisms can be locked to the corresponding protrusions. An adjustable pin mechanism is provided on the outer side of the door body. A sealing strip is provided at the opening.

[0006] The double-locking hook mechanism includes an upper locking hook, a lower locking hook, a locking hook cylinder, and a pull rod. The upper locking hook and the lower locking hook are rotatably connected to both sides of the opening. One end of the upper locking hook is hinged to one end of the pull rod, and the other end of the pull rod is hinged to one end of the lower locking hook. A locking hook cylinder is also installed on the opening, and the output end of the locking hook cylinder is hinged to one end of the lower locking hook.

[0007] As a preferred technical solution of this utility model, the adjustable bolt mechanism includes a bolt locking block, a tapered bolt, a bolt cylinder, and a slide rail. The bolt cylinder is installed on the door body, and a T-shaped shaft is fixedly connected to the output end of the bolt cylinder. The two sides of the T-shaped shaft are slidably connected to the slide rail. A tapered bolt is fixed to the front end of the T-shaped shaft, and a bolt locking block is fixedly installed at the lower end of the opening. The tapered bolt can be inserted into the bolt locking block.

[0008] As a preferred technical solution of this utility model, the upper and lower locking hooks adopt a lever structure, and synchronous movement is achieved through the connection of the pull rod.

[0009] As a preferred technical solution of this utility model, the slide is configured as a long slot to accommodate the different installation angles of the pin cylinder.

[0010] As a preferred embodiment of this utility model, the middle part of the locking block of the pin is provided with a crossbar, and the crossbar is perpendicular to the tapered pin.

[0011] Compared with related technologies, the composite locking device for the integrated unloading door of the container provided by this utility model has the following advantages:

[0012] In use, this technical solution involves first opening the door for waste feeding, then closing the door. Two sets of double-locking hook mechanisms utilize lever principles to achieve low-torque locking. At this time, the output end of the locking hook cylinder extends, causing the lower locking hook to rotate upwards around the fulcrum, while the upper locking hook rotates upwards by the same angle. When the upper and lower locking hooks simultaneously hook their corresponding protrusions, the door is locked. Simultaneously, the adjustable pin mechanism's pin cylinder extends, and its output end drives the T-shaft to move on the slide rail. The T-shaft simultaneously drives the conical pin to extend, entering the pin locking block. Through the contact between the outer surface of the conical pin and the crossbar, pressure is gradually applied, locking the door to compensate for localized gaps in the double-locking hook mechanism.

[0013] The integrated box uses a combination of two sets of double-locking hook mechanisms and an adjustable pin mechanism to ensure uniform distribution of sealing pressure. The double-locking hook mechanism effectively prevents loosening through double-layer locking of the upper and lower hooks, adapting to long-term vibration conditions. Attached Figure Description

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] Example

[0023] like Figures 1-5 As shown, this utility model discloses a composite locking device for a combined unloading door of a container, comprising a container body 1, an opening at one end of the container body 1, and a door body 2 hinged to the upper end of the opening, allowing the door body 2 to be opened and closed. Symmetrical double-locking hook mechanisms 3 are respectively provided on both sides of the opening. Two protrusions 4 are provided on both sides of the door body 2. When the double-locking hook mechanism 3 is locked to the corresponding protrusion 4, the door body 2 is locked. Conversely, the door body 2 is opened. An adjustable pin mechanism 5 is provided on the outer side of the door body 2, which can lock the door body 2 a second time. A sealing strip is provided at the opening.

[0024] Furthermore, the double-locking hook mechanism 3 includes an upper locking hook 31, a lower locking hook 32, a locking hook cylinder 33, and a pull rod 34. Both the upper locking hook 31 and the lower locking hook 32 are rotatably connected to opposite sides of the opening. One end of the upper locking hook 31 is hinged to one end of the pull rod 34, and the other end of the pull rod 34 is hinged to one end of the lower locking hook 32. A locking hook cylinder 33 is also installed on the opening, with its output end hinged to one end of the lower locking hook 32. The upper locking hook 31 and the lower locking hook 32 are connected by a lever. The structure achieves synchronous movement through the connection of the pull rod 34. It can be understood that the locking hook cylinder 33 works, and its output end extends and retracts to drive the lower locking hook 32 to rotate around the fulcrum. Utilizing the lever principle, the upper locking hook 31, the lower locking hook 32 and the pull rod 34 form a parallelogram-like shape. Therefore, when the lower locking hook 32 rotates, the upper locking hook 31 rotates at the same angle. When the upper locking hook 31 and the lower locking hook 32 hook the corresponding protrusion 4 at the same time, the door body 2 can be locked.

[0025] The adjustable latch mechanism 5 includes a latch locking block 51, a tapered latch 52, a latch cylinder 53, and a slide rail 54. The latch cylinder 53 is mounted on the door body 2. A T-shaped shaft is fixedly connected to the output end of the latch cylinder 53. The two sides of the T-shaped shaft are slidably connected to the slide rail 54. A tapered latch 52 is fixed to the front end of the T-shaped shaft, and a latch locking block 51 is fixedly installed at the lower end of the opening. The tapered latch 52 can be inserted into the interior of the latch locking block 51. The slide rail 54 is designed as a long slot to accommodate different installation angles of the latch cylinder 53. To meet the requirements of the locking mechanism, a crossbar 511 is provided in the middle of the locking block 51. The crossbar 511 is perpendicular to the tapered pin 52. It can be understood that when the locking cylinder 53 extends, the output end of the locking cylinder 53 drives the T-shaped shaft to move on the slide rail 54. At the same time, the T-shaped shaft drives the tapered pin 52 to extend. The tapered pin 52 enters the locking block 51. After the outer surface of the tapered pin 52 contacts the crossbar 511, pressure is gradually applied to lock the door 2 to compensate for the local gap of the double-locking hook mechanism 3.

[0026] When using this technical solution, the door 2 is first opened for garbage feeding, and then the door 2 is closed. The two sets of double-locking hook mechanisms 3 utilize the lever principle to achieve low-torque locking. At this time, the output end of the locking hook cylinder 33 extends out and drives the lower locking hook 32 to rotate upward around the fulcrum. At the same time, the upper locking hook 31 rotates upward by the same angle. When the upper locking hook 31 and the lower locking hook 32 simultaneously hook the corresponding protrusion 4, the door 2 can be locked. At the same time, the pin cylinder 53 of the adjustable pin mechanism 5 extends out. The output end of the pin cylinder 53 drives the T-shaped shaft to move on the slide 54. The T-shaped shaft simultaneously drives the conical pin 52 to extend out. The conical pin 52 enters the interior of the pin locking block 51. After the outer surface of the conical pin 52 contacts the crossbar 511, pressure is gradually applied, which can lock the door 2 to compensate for the local gap of the double-locking hook mechanism 3.

[0027] The integrated box uses a combined mechanism of two sets of double-locking hook mechanisms 3 and adjustable pin mechanism 5 to make the sealing pressure distribution uniform. The double-locking hook mechanism 3 effectively prevents loosening through the double-layer locking of upper hook 31 and lower hook 32, and is suitable for long-term vibration conditions.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
