Description

Technical Field

[0001] This utility model relates to the field of door control technology, and in particular to a door opening and closing control device. Background Technology

[0002] During engine manufacturing, due to the large number of parts, each part is stored in a different storage box. When a specific part is needed, the door of the corresponding storage box is opened. However, because there are many similar parts, it is easy for workers to pick the wrong part, which can lead to the assembly of a defective engine.

[0003] To address the aforementioned issues, existing storage boxes are equipped with automatic control devices on their doors, which open the doors by reading corresponding signals. However, existing control devices all use electric cylinders, and the entire control system is a single unit. Because electric cylinders are prone to damage, and once damaged, the entire system must be replaced, this not only results in high procurement costs but also high subsequent operating costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a door opening and closing control device that extends service life, allows for the replacement of parts, eliminates the need for complete replacement when damaged, and reduces costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A door opening and closing control device includes a solenoid valve and a rotary cylinder fixed above the door. The piston rod of the rotary cylinder is used to connect to the door. The solenoid valve is used to receive signals from a control module. The air inlet of the rotary cylinder is connected to the air outlet of the solenoid valve through a first air inlet pipe. The air inlet of the solenoid valve is connected to an air source through a second air inlet pipe.

[0007] Preferably, it also includes a mounting bracket for connecting a storage box for placing parts, and the cylinder of the rotary cylinder is connected to the mounting bracket.

[0008] Preferably, a mounting bracket is connected to the piston rod, and the mounting bracket is used to connect the door body.

[0009] Preferably, it includes a connecting shaft, and the middle part of the connecting shaft is connected to the piston rod, and each end of the piston rod is provided with a mounting bracket.

[0010] Preferably, the mounting bracket is rectangular, and the mounting bracket has mounting holes extending along its length.

[0011] Preferably, a flow restrictor is provided between the rotary cylinder and the first air intake pipe.

[0012] Preferably, the air inlet of the solenoid valve is provided with a quick connector, and the second air inlet pipe is connected to the quick connector.

[0013] Preferably, the solenoid valve is equipped with a silencer.

[0014] This utility model discloses a door opening and closing control device. Compared with the prior art, its advantages are as follows: By using a rotary cylinder to connect to the door, and simultaneously setting up a solenoid valve to receive signals from the control module, the air inlet of the rotary cylinder is connected to the air outlet of the solenoid valve through a first air inlet pipe, and the air inlet of the solenoid valve is connected to an air source through a second air inlet pipe. Therefore, when the corresponding door needs to be opened or closed, the control module only needs to send a signal, and the solenoid valve of the corresponding component receives the signal, opening the solenoid valve and causing the rotary cylinder to drive the corresponding door to open or close. This not only simplifies operation but also greatly extends the service life and reduces procurement costs by using a cylinder instead of an electric cylinder. Furthermore, since the rotary cylinder and the solenoid valve are connected through the first air inlet pipe, all components are easily disassembled and installed. When a component is damaged, only the corresponding component needs to be replaced, rather than replacing the entire device, thus reducing operating costs. Attached Figure Description

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0020] like Figure 1 As shown, a preferred embodiment of the present invention provides a door opening and closing control device, comprising a solenoid valve 1 and a rotary cylinder 2 fixed above the door. The piston rod of the rotary cylinder 2 is used to connect to the door. The solenoid valve 1 is used to receive signals from a control module. The control module is an existing control system, operated via a display screen showing the names of corresponding engine assembly parts. Each storage box is equipped with one of the door opening and closing control devices. The solenoid valve 1 of each door opening and closing control device is electrically connected to the control module. To open the door of a specific part, operation is performed on the display screen, thereby opening the solenoid valve 1 of the corresponding door opening and closing control device and driving the opening and closing of the corresponding door. The air inlet of the rotary cylinder 2 is connected to the air outlet of the solenoid valve 1 through a first air inlet pipe 3, and the air inlet of the solenoid valve 1 is connected to an air source through a second air inlet pipe 4.

[0021] The door opening and closing control device based on the above technical features uses a rotary cylinder 2 connected to the door body, and a solenoid valve 1 receiving signals from the control module. The air inlet of the rotary cylinder 2 is connected to the air outlet of the solenoid valve 1 through a first air inlet pipe 3, and the air inlet of the solenoid valve 1 is connected to an air source through a second air inlet pipe 4. Therefore, when the corresponding door needs to be opened or closed, the control module only needs to send a signal, and the corresponding component, the solenoid valve 1, receives the signal, opens, and the rotary cylinder 2 drives the corresponding door body to open or close. This not only simplifies operation but also significantly extends the service life and reduces procurement costs by using a pneumatic cylinder instead of an electric cylinder. Furthermore, since the rotary cylinder 2 and the solenoid valve 1 are connected through the first air inlet pipe 3, all components are easily disassembled and installed. When a component fails, only that component needs to be replaced, rather than the entire device, further reducing operating costs.

[0022] In this embodiment, the doors are all installed on the storage box for storing engine parts. To facilitate the fixing of the rotary cylinder 2, a fixing frame 5 can be provided. The fixing frame 5 is fixed on the storage box, and the cylinder of the rotary cylinder 2 is connected to the fixing frame 5, which ensures the stable installation of the rotary cylinder 2 and the accuracy of its installation position.

[0023] Meanwhile, to facilitate the connection of the piston rod of the rotary cylinder 2 to the door body, a mounting bracket 6 is connected to the piston rod for connecting the door body. Specifically, a connecting shaft 7 is connected to the piston rod, and the middle part of the connecting shaft 7 is connected to the piston rod. A mounting bracket 6 is provided at each end of the piston rod. Since the piston rod connects to the upper end of the door body during connection, and the door body rotates around its upper end, connecting the door body with two mounting brackets 6 ensures the stability of the connection between the piston rod and the door body, guaranteeing that the rotary cylinder 2 can drive the door body to rotate normally, thus opening or closing the door. Alternatively, there can be two connecting shafts 7, one end of which is connected to the piston rod of the rotary cylinder 2, and the other end is connected to one mounting bracket 6.

[0024] In addition, to ensure the connection strength and stability between the mounting bracket 6 and the door body, the mounting bracket 6 is rectangular and has mounting holes 11 extending along its length. During installation, the mounting holes 11 are connected to the door body by screws or the like to ensure the connection between the mounting bracket 6 and the door body.

[0025] In this embodiment, a flow restrictor 8 is provided between the rotary cylinder 2 and the first air inlet pipe 3. The flow restrictor 8 controls the opening or closing rate of the door, ensuring safety during use. Simultaneously, to facilitate the connection of the second air inlet pipe 4 to the solenoid valve 1, a quick connector 9 can be provided at the air inlet of the solenoid valve 1. The second air inlet pipe 4 connects to the quick connector 9, facilitating installation and replacement. Furthermore, since the solenoid valve 1 vibrates to some extent during operation due to airflow, a silencer 10 is provided on the solenoid valve 1 to reduce its vibration and improve the working environment.

[0026] The solenoid valve 1 can be the SMC brand SY5120-5DZD-C4-Q model.

[0027] Furthermore, the door opening and closing control device of this application has a simple structure and is easy to manufacture, with an ordering cycle of approximately 35 working days, which is significantly shorter than the previous device's ordering cycle of 120 working days. At the same time, the previous electric cylinder control device had a lifespan of approximately one year per unit, while this application uses a rotary cylinder 2, achieving a lifespan of 10 years per unit, greatly improving the service life.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
