Description

Technical Field

[0001] This utility model relates to the field of display control device technology, specifically to a display control device for a fresh air system. Background Technology

[0002] A fresh air system display and control device is a device used to monitor and control a fresh air system. It has functions such as data display, mode control, remote control, and alarm reminder. Common types include wall-mounted controllers, touch screen color screen controllers, and smart APP controllers.

[0003] A search revealed a Chinese patent application (CN202323450011.3) proposing a display screen control device, comprising a display screen body and a wall. A plug is fixedly connected to the rear of the display screen body, and a socket is fixedly connected to one side of the wall. Electric cylinders are installed on both sides of the socket, and three fixing rods are installed at the output ends of both electric cylinders. The fixing rods on both sides movably penetrate the two side walls of the socket. In this prior art, by setting electric cylinders and fixing rods, the display screen body can be inserted into the socket via the plug. The controller synchronously controls the two electric cylinders, causing them to extend, thereby driving the fixing rods on both sides to insert into the plug and socket, thus fixing the plug and socket. When disassembly is required, simply pull the fixing rods on both sides outwards using the controller, and then lift the plug out of the socket to disassemble the display screen body, achieving the effect of quick installation and disassembly of the display screen body.

[0004] In the aforementioned prior art, the control device is quickly installed by extending and retracting electric cylinders on both sides of the wall to insert a fixing rod into the interior of the control device. While this method of quick plug-in installation using electric cylinders is relatively convenient and stable, the electric cylinders are prone to dust accumulation or malfunction due to air and moisture corrosion after long-term use. This makes it difficult to quickly remove the control device, requiring complete replacement or repair, which makes the use of the control device inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a display control device for a fresh air system, which solves the problem that in the prior art, when a display control device for a fresh air system uses an electric cylinder to push a fixing rod into the control device for fixing, the electric cylinder is prone to failure, making the control device difficult to remove.

[0006] This utility model provides the following technical solution: a display control device for a fresh air system, including a housing, a circuit board fixedly connected to the inner side of one end of the housing, and a connecting end fixedly connected to the middle of the circuit board, and a disassembly assembly provided at the end of the housing away from the circuit board, and the disassembly assembly including a fixing plate attached to the outer side of the end of the housing away from the circuit board, and screws engaged with the internal threads of the fixing plate at both ends.

[0007] The above technical solution involves using multiple sets of screws to install the fixing plate onto the wall.

[0008] As a preferred embodiment of the above technical solution, baffles are fixedly connected to both ends of the fixing plate, and a locking block is inserted inside the baffle. A first spring is fixedly connected to the end of the locking block away from the outer shell, and the end of the first spring away from the locking block is fixedly connected to the baffle.

[0009] Through the above technical solution, the elastic potential energy of the first spring can push the card block out and insert it into the outer shell for locking.

[0010] As a preferred embodiment of the above technical solution, a plate is provided at one end of the first spring, and a second spring is fixedly connected to the end of the plate away from the first spring, and the end of the second spring away from the plate is fixedly connected to the baffle.

[0011] The above technical solution allows the elastic potential energy of the second spring to pull the insert plate back into place.

[0012] As a preferred embodiment of the above technical solution, the middle of the card block is provided with a slot, and the end of the card block away from the first spring is inserted into the outer shell.

[0013] The above technical solution allows for the insertion of a plate through a slot in the middle of the card block, thereby facilitating the movement of the card block.

[0014] As a preferred embodiment of the above technical solution, a connecting plate is fixedly connected to one end of the insert plate near the second spring, and a push block is fixedly connected to the other end of the connecting plate away from the insert plate through the baffle.

[0015] Through the above technical solution, the pusher block can be driven by the connecting plate to move the insert plate and insert it into the card block.

[0016] As a preferred embodiment of the above technical solution, a card plate is fixedly connected to the inner side of the middle end of the fixed plate, and multiple sets of card plates are arranged in a circumferential array.

[0017] The above technical solution utilizes multiple sets of circumferentially arrayed card plates to wrap and restrict the connecting wires.

[0018] As a preferred embodiment of the above technical solution, the multiple sets of card plates are spaced 3 cm apart, and the card plates are L-shaped.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This display and control device for a fresh air system can be quickly installed by disassembling and assembling components, eliminating the need for electric operation and effectively avoiding the impact of disassembly and assembly failures caused by electric malfunctions.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a display control device for a fresh air system, including a housing 1, a circuit board 11 fixedly connected to the inner side of one end of the housing 1, and a connecting end 12 fixedly connected to the middle of the circuit board 11. A disassembly assembly 2 is provided at the end of the housing 1 away from the circuit board 11, and the disassembly assembly 2 includes a fixing plate 21 attached to the outer side of the end of the housing 1 away from the circuit board 11. Screws 22 are engaged with the internal threads at both ends of the fixing plate 21. The control device can be quickly installed through the disassembly assembly 2 without the need for electric operation, which can effectively avoid the disassembly and installation impact caused by electric failure.

[0029] like Figure 3As shown, baffles 23 are fixedly connected to both ends of the fixed plate 21, and a locking block 24 is inserted inside the baffle 23. A first spring 25 is fixedly connected to the end of the locking block 24 away from the outer shell 1, and the end of the first spring 25 away from the locking block 24 is fixedly connected to the baffle 23. The elastic potential energy of the first spring 25 is used to push the locking block 24 out, so that the locking block 24 is inserted into the outer shell 1 to lock and fix the outer shell 1.

[0030] like Figure 3 As shown, a first spring 25 is provided with a plate 26 at one end, and a second spring 27 is fixedly connected to the end of the plate 26 away from the first spring 25. The end of the second spring 27 away from the plate 26 is fixedly connected to the baffle 23. The elastic potential energy of the second spring 27 is used to pull the plate 26 back to its original position.

[0031] like Figure 3 and Figure 4 As shown, a slot is provided in the middle of the card block 24, and the end of the card block 24 away from the first spring 25 is inserted into the outer casing 1. By providing a slot in the card block 24, it is easy to insert the insert plate 26.

[0032] like Figure 3 As shown, a connecting plate 28 is fixedly connected to one end of the insert plate 26 near the second spring 27, and a push block 29 is fixedly connected to the other end of the connecting plate 28 away from the insert plate 26 through the baffle 23. Pushing the push block 29 causes the connecting plate 28 to push the insert plate 26. After the insert plate 26 is pushed, it stretches the second spring 27 and inserts into the locking block 24. As the insert plate 26 continues to be inserted into the locking block 24, it squeezes the locking block 24. After being squeezed, the locking block 24 is inserted into the baffle 23 and compresses the first spring 25, thereby releasing the locking of the outer shell 1.

[0033] like Figure 5 As shown, a card plate 210 is fixedly connected to the inner side of the middle end of the fixed plate 21, and multiple sets of card plates 210 are arranged in a circumferential array.

[0034] like Figure 5 As shown, multiple sets of card plates 210 are spaced 3 cm apart, and the card plates 210 are L-shaped to facilitate the wrapping and restriction of the connecting wires using multiple sets of card plates 210.

[0035] Working principle: When installing the outer casing 1, first pass the connecting wire through the slot in the middle of the fixing plate 21, then fix the fixing plate 21 to the wall with multiple sets of screws 22. Next, connect the connecting wire passing through the slot in the fixing plate 21 to the connecting end 12, and then wrap the excess connecting wire around the outside of the clamping plate 210. Then, with the outer casing 1 restrained by the two sets of baffles 23, it is pressed against the fixing plate 21. During insertion, first manually press the clamping blocks 24 on both sides. After the clamping blocks 24 are pressed, they are inserted into the baffles 23, compressing the first spring 25. Then, when the outer casing 1 is inserted into the clamping blocks 24, release the pressed clamping blocks 24. At this time, the outer casing 1 presses against the clamping blocks 24. When the outer casing 1 is in contact with the fixing plate 21... At this point, the elastic potential energy of the first spring 25 pushes the locking block 24 out and inserts it into the outer shell 1 to lock and fix the outer shell 1. When removing it later, push the push blocks 29 on both sides. After the push blocks 29 are pushed, they drive the connecting plate 28 to push the insert plate 26. After the insert plate 26 is pushed, it stretches the second spring 27 and inserts it into the locking block 24. As the insert plate 26 continues to be inserted into the locking block 24, it squeezes the locking block 24. After the locking block 24 is squeezed, it inserts into the baffle 23 and compresses the first spring 25. When the locking block 24 is pulled out of the outer shell 1, the outer shell 1 can be pulled to remove it. After removal, release the push block 29 and use the elastic potential energy of the second spring 27 to pull the insert plate 26 and the connecting plate 28 back to their original positions.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
