The end plate is used for the data acquisition module, which includes an acquisition element and an annular cover plate for accommodating the acquisition element. The end plate is used to fasten to the annular cover plate. The end plate is characterized by comprising: an end plate body made of aluminum alloy, with a first mounting portion with an edge recessed on the side of the end plate near the annular cover plate to form an annular stepped structure; and a sealing ring surrounding the outer periphery of the first mounting portion and fitting between the contact surfaces of the end plate body and the annular cover plate.

[0004] However, the existing support structure of the data acquisition board also has certain shortcomings. The existing support structure of the data acquisition board is mostly a simple fixed-position support component for supporting the data acquisition board and welding it. Since the heat dissipation efficiency of the data acquisition board is related to the airflow during subsequent use, the data acquisition board with a fixed height design and installation has poor heat dissipation efficiency. Summary of the Invention

[0005] The purpose of this utility model is to provide a support structure for a data acquisition board, which solves the problem that existing data acquisition board support structures often use fixed-position support components for support and welding. Since the heat dissipation efficiency of the data acquisition board is related to the airflow during subsequent use, the heat dissipation efficiency of data acquisition boards designed and installed at a fixed height is poor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a support structure for a data acquisition board, comprising an acquisition board body, a screw movably connected to the inner wall of the acquisition board body, a washer slidably sleeved on the outer side of the screw, the washer contacting the acquisition board body, a locking nut threadedly connected to the outer side of the screw, the locking nut contacting the washer, a limiting hole formed on the surface of the locking nut, a locking ring threadedly connected to the outer side of the screw, the locking ring contacting the locking nut, a limiting rod threadedly connected to the inner wall of the locking ring, the limiting rod movably connected to the limiting hole, a connecting cylinder fixedly connected to the lower end of the screw, the connecting cylinder contacting the acquisition board body, and an adjustment mechanism provided on the connecting cylinder.

[0007] Preferably, four screws are provided, which are evenly distributed on the acquisition plate body. The screws can be used for the installation of the connecting cylinder.

[0008] Preferably, multiple limiting holes are provided, and the multiple limiting holes are arranged in a circular array on the locking nut. The setting of the limiting holes facilitates the insertion and limiting use with the limiting rod.

[0009] Preferably, the locking ring has multiple friction grooves on its side, and the multiple friction grooves are arranged in a circular array on the locking ring. The setting of the friction grooves makes it convenient for the operator to push the locking ring to rotate.

[0010] Preferably, the adjustment mechanism includes a telescopic rod, which is slidably connected to the inner wall of the connecting cylinder. A support foot is fixedly connected to the lower end of the telescopic rod. A slot is provided on the side of the telescopic rod. An installation cylinder is fixedly connected to the side of the connecting cylinder. An end rod is slidably connected to the inner wall of the installation cylinder. The end plate of the end rod contacts the installation cylinder. A retaining plate is fixedly connected to the horizontal part of the end rod. The retaining plate is slidably connected to the connecting cylinder and the slot. A spring is provided on the outer side of the horizontal part of the end rod. Through the cooperation of the retaining plate and the slot, the telescopic rod can be limited after adjustment, thereby making the acquisition plate body stable after adjustment and improving the airflow at the bottom of the acquisition plate body.

[0011] Preferably, multiple slots are provided, and the multiple slots are evenly distributed on the telescopic rod. The design of the slots facilitates the insertion and use of the card plate.

[0012] Preferably, one end of the spring is welded to the mounting cylinder, and the other end of the spring is welded to the clamping plate. The clamping plate can be connected and used by means of the spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a screw and a locking nut to fix the connecting cylinder. The locking nut can be tightened by the action of the gasket. With the help of the locking ring, the limiting rod, the limiting hole and other structures, the locking nut can be limited to avoid the problem of loosening due to vibration.

[0015] 2. This utility model allows the acquisition plate body to be welded and fixed by the setting of the support legs. With the action of the telescopic rod and the connecting cylinder, the position of the acquisition plate body can be adjusted. With the structure of the slot and the plate, the acquisition plate body can be stabilized after adjustment, so as to improve the air circulation at the bottom of the acquisition plate body and thus ensure good heat dissipation.

[0028] The support leg 102 allows for welding of the acquisition plate body 1 to the controller and other related components. The support leg 102, telescopic rod 101, and connecting cylinder 9 provide support for the acquisition plate body 1. Pulling the end rod 105 away from the mounting cylinder 104 moves the clamping plate 106, causing the spring 107 to deform and disengage from the clamping slot 103. Then, pulling the acquisition plate body 1 moves the telescopic rod 101 along the inner wall of the connecting cylinder 9, adjusting the position of the acquisition plate body 1. Releasing the end rod 105 allows the spring 107 to return to its original shape, pulling the clamping plate 106 into the next clamping slot 103. This stabilizes the acquisition plate body 1, allowing for adaptive adjustments to the airflow at the bottom of the acquisition plate body 1 to ensure good heat dissipation.
