The system can effectively collect, monitor and record process parameters at the production site, providing strong information support for improving product quality and reducing production costs. Especially in modern multi-channel acquisition systems, data collection and processing of many sensors or signal sources has become an indispensable operation. However, most existing test systems adopt a single-channel design, which makes single product testing time-consuming and inefficient, and causes a lot of waste of resources.

[0003] The existing acquisition system assembly is accompanied by a rapid increase in temperature during operation, which is prone to many safety hazards. It is often necessary to connect additional heat dissipation devices, which makes the entire system structure complicated and cumbersome. In different environments, there are certain requirements for the operating position and height of the system. Conventional acquisition system assemblies do not have the function of adjusting the height and can only be placed manually.

[0004] Therefore, a lifting and cooling mechanism and a multi-channel switching device with height adjustment and heat dissipation functions are needed to simplify the structure and size of the acquisition system itself, and to efficiently control switch switching, and to match them with a fast control module to achieve precise and high-speed channel switching to meet the needs of the existing environment.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

[0033] Example 1

[0034] Reference Figures 1-2 , which is the first embodiment of the utility model, and this embodiment provides a lifting heat dissipation mechanism.

[0035] The extension component 100 is used to realize the lifting and recovery of the lifting heat dissipation mechanism. A matching sleeve 102 is fixedly arranged at the center of the stable chassis 101, and a cooling support plate 103 is arranged above the matching sleeve 102. The cooling support plate 103 can slide along the inner wall of the matching sleeve 102 to change the height.

[0036] The limit assembly 200 is used to assist the rise and fall of the cooling support plate 103 and to limit the rise of the cooling support plate 103 in one direction. A gear shaft 201 is provided on the surface of the stable chassis 101 and one side of the matching sleeve 102, and the two ends of the gear shaft 201 are torsionally connected to the stable chassis 101. There is a certain distance between the gear shaft 201 itself and the surface of the stable chassis 101 and the side wall of the matching sleeve 102. Below the gear shaft 201, an operating plate 202 is slidably provided. The surface of the operating plate 202 is meshed with the gear shaft 201. The operating plate 202 can drive the gear shaft 201 to rotate while sliding horizontally, and vice versa. The lifting rod 203 is slidably provided on the side wall of the matching sleeve 102. The lifting rod 203 is also fixedly connected to the cooling support plate 103 while meshing with the gear shaft 201.

[0037] When the operating panel 202 slides horizontally toward the outside of the stable chassis 101, it can drive the gear shaft 201 meshing therewith to rotate. The gear shaft 201 generates a resetting force through the torque during the rotation. While rotating, the gear shaft 201 drives the lifting rod 203 to rise, pushing the cooling support plate 103 to rise. A locking unit 204 is provided on one side of the operating panel 202 for sliding. The locking unit 204 can provide a one-way locking function for the translational movement of the operating panel 202, thereby ensuring that the cooling support plate 103 will not be lowered under the action of gravity even if the operator lets go during the rising process. Pulling the locking unit 204 can release the cooperation between the locking unit 204 and the operating panel 202, so that the operating panel 202 will move in the opposite direction under the torsional reversal of the gear shaft 201, thereby driving the cooling support plate 103 to descend.

[0038] The adjustment component 300 can be matched with a fast control module to achieve accurate and high-speed channel switching. The housing 301 provides protection and accommodation for the entire set of adjustment components 300. The housing 301 is placed on the cooling support plate 103, and the operating panel 202 is pulled to drive the cooling support plate 103 and the housing 301 to rise. The control mainboard 303 is fixedly set at the bottom of the housing 301, and is used to receive signals from an external computer or operating panel, and control the switching board 302 in the housing 301 to achieve the selection of different channels or communication operation with external connection devices.

[0039] Example 2

[0040] Reference Figures 1 to 4 , which is the second embodiment of the present utility model, is based on the previous embodiment, but differs in that the structure of the extension component 100 and the matching structure of the limiting component 200 are further optimized.

[0041] A cooling fan 104 is fixedly arranged inside the cooling support plate 103, and the cooling fan 104 can be manually started after the housing 301 is placed to ventilate and cool down. A lifting groove 102a is fixedly provided at the center of the matching sleeve 102, and a telescopic rod 103a is fixedly arranged at the bottom of the cooling support plate 103. The telescopic rod 103a can slide along the lifting groove 102a, so that the cooling support plate 103 can be adjusted in height along the lifting groove 102a. A pair of extension bosses 101a are fixedly arranged at the bottom of the stable chassis 101, and the gear shaft 201 and the extension boss 101a are connected by torsion rotation.

[0042] Two slide grooves 101b are fixedly provided on the surface of the stable chassis 101 below the two sides of the gear shaft 201, and the operating panel 202 slides along the slide grooves 101b, and the stable linear motion of the operating panel 202 can be ensured by the slide grooves 101b. An array of limiting teeth 202a is fixedly provided on the side wall of the operating panel 202, and on the other side of the limiting teeth 202a, a locking unit 204 is connected to the surface of the stable chassis 101 by torsion rotation, and the tip of the locking unit 204 is located between the limiting teeth 202a. Since the locking unit 204 is connected to the surface of the stable chassis 101 by torsion rotation, the operating panel 202 will not be affected by the locking unit 204 when it moves outward and drives the cooling support plate 103 to rise.

[0043] A blocking protrusion 204a is also provided on one side of the locking unit 204. The blocking protrusion 204a itself is vertically slidably connected to the stable chassis 101. In the default state, the blocking protrusion 204a can prevent the reverse rotation of the locking unit 204, thereby being able to one-way lock the rise of the cooling support plate 103. Only when the cooling support plate 103 needs to be lowered and reset, the blocking protrusion 204a is manually pulled up to dislocate the blocking protrusion 204a and the locking unit 204. At this time, the locking unit 204 will be moved under the reverse movement of the operating plate 202, so that the reverse movement of the operating plate 202 can no longer be blocked. The movement of the operating plate 202 and the gear shaft 201 will not be affected and can return to the original position normally, and the cooling support plate 103 descends to the initial position. An operating handle 202b is fixedly provided at one end of the operating plate 202 to facilitate the staff to pull and operate.

[0044] A pneumatic sleeve 105 is fixedly provided on the surface of the stable chassis 101, and a buffer piston 105a is slidably provided on the inner wall of the pneumatic sleeve 105. The other end of the buffer piston 105a is fixedly connected to the bottom of the cooling pallet 103. The rise and fall of the cooling pallet 103 will drive the linear movement of the buffer piston 105a. An exhaust hole 105b is fixedly provided at the bottom of the pneumatic sleeve 105. When the buffer piston 105a descends, the descending movement of the buffer piston 105a will be limited by the air pressure and slowed down due to the small size of the exhaust hole 105b. This structure can slow down the descent of the cooling pallet 103. If the housing 301 is placed on the cooling pallet 103, it can descend more safely and smoothly.

[0045] Example 3

[0046] Reference Figures 1 to 6 , which is the third embodiment of the utility model. This embodiment is based on the above embodiment and adds a multi-channel switching device.

[0047] The adjustment assembly 300 is used in conjunction with the fast control module to achieve accurate and high-speed channel switching, and the housing box 301 provides protection and accommodation for the entire adjustment assembly 300. The housing box 301 is placed on the cooling support plate 103, and the operating panel 202 is pulled to drive the cooling support plate 103 and the housing box 301 to rise.

[0048] The control mainboard 303 is fixedly arranged at the bottom of the housing 301, and is used to receive signals from an external computer or operation panel, and control the switch board 302 in the housing 301, so as to realize the selection of different channels or the communication operation with external connection devices. A liquid crystal control screen 301a is fixedly arranged on the surface of the housing 301, and a signal input port 301b is also fixedly arranged on one side of the liquid crystal control screen 301a, and the signal input port 301b is directly electrically connected to the control mainboard 303 arranged in the housing 301. The control mainboard 303 is fixedly arranged at the bottom of the housing 301, and is used to receive signals from an external computer or operation panel, and control the switch board 302 in the housing 301.

[0049] When the operator uses the LCD control screen 301a to make settings, the left side of the LCD control screen 301a displays the current channel number, and the operator can select the previous channel or the next channel through the left and right options. The bottom of the storage box 301 is fixedly provided with heat dissipation ventilation holes 301c, which are used to directly connect with the cooling support plate 103 to facilitate ventilation and cooling in the storage box 301.

[0050] A main switch 301d is provided on the other side of the LCD control screen 301a, and a Type-C control interface 301d-1 is provided below the main switch 301d. A USB control interface 301d-2, an Ethernet control interface 301d-3, an RS232 control interface 301d-4, and a power input port 301d-5 are arranged and fixedly installed on the right side of the Type-C control interface 301d-1. The switching board 302 in this design uses 6 multi-channel switching cards, each of which supports the switching of 16 channels. Through the internal cascade interface, a single machine can achieve the switching of 16*6=96 signal channels. If necessary, the user can increase the number of signal channels by additional multi-machine communication cascade to meet the required number of multi-channel signal channels. For example, only two machines are needed to achieve the test number of 96*2=192 channels.
