[0002] In the modern construction and decoration industries, as a new type of building material, flame-retardant wood-based panels are becoming increasingly important. They integrate multiple excellent properties such as flame retardancy, compressive resistance, environmental protection, and durability, and are widely used in various structural parts such as walls, ceilings, and floors. Especially in places with strict fire safety requirements such as data centers, high-rise buildings, and underground facilities, they are essential.
[0003] When most flame-retardant boards are tested, the four sides of the flame-retardant board are fixed by a fixing frame on the device, and finally pressure detection is carried out. However, such a detection method cannot well fix flame-retardant boards of different specifications, resulting in the situation that the flame-retardant board is likely to slip during pressure detection, affecting the detection effect. Summary of the Utility Model
[0004] The purpose of the utility model is to address the deficiencies of the prior art by providing a device for detecting the compressive resistance of a flame-retardant board to solve the problems raised in the above background art.

The limiting mechanism includes a fixed seat, a sliding seat, a screw rod, a limiting rod, and a stop block. The sliding seats are two groups arranged oppositely and slide on the fixed seat. The screw rods are two and are arranged oppositely at both ends of the sliding seat. The limiting rod is arranged on the screw rod and is locked on the screw rod by a nut. The stop block is arranged by being embedded in a slot on the side of the fixed seat and is used to limit the sliding seat from moving in one direction.
[0006] By adopting the above technical solution, flame-retardant boards of different sizes can be restricted and limited, realizing rapid adjustment.
[0007] Two mutually parallel guide rails are further installed in the middle of the fixed seat, and the middle part of the sliding seat slides along the guide rails.
[0008] By adopting the above technical solution, it is convenient to move the sliding seat.
[0009] The inner wall contour of the slot is adapted to the outer wall contour of the stop block.
[0010] By adopting the above technical solution, after the stop block is embedded in the slot, it has stability.
[0011] The middle part of the upper end of the sliding seat is provided with an inverted trapezoidal groove.
[0012] By adopting the above technical solution, it is convenient to support fire retardant boards of different sizes and cooperate with the limiting rod for limiting.
[0013] Through holes are provided at both ends of the limiting rod, and the limiting rod is sleeved on the screw through the through holes.
[0014] By adopting the above technical solution, it is convenient to adjust the position of the limiting rod and limit the fire retardant board.
[0015] The beneficial effects of the fire retardant board compressive resistance detection device of the present utility model are as follows:
[0016] According to the size of the detected fire retardant board, push the two sliding seats closer or farther away, then insert the block into the notch, limit the degree of freedom in one side direction of the sliding seat, then place the fire retardant board on the two sliding seats for support, then place the limiting rod on the screw, and lock the height of the limiting rod through the nut. At this time, the limiting rod can limit both ends of the fire retardant board. This device can limit and position fire retardant boards of different sizes and achieve rapid adjustment.

[0020] The following elaborates on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.
[0021] Refer to Figure 1-2 , a fire retardant board compressive resistance detection device, including a support 1, a hydraulic cylinder 2 installed on the support 1, a pressure sensor 3 installed at the output end of the hydraulic cylinder 2, and a limiting mechanism installed on the support 1. The limiting mechanism includes a fixed seat 4, a sliding seat 5, a screw 6, a limiting rod 8 and a block 9. The sliding seats 5 are two groups and slide oppositely on the fixed seat 4. There are two screws 6, which are opposed to both ends of the sliding seat 5. The limiting rod 8 is arranged on the screw 6 and is locked on the screw 6 through a nut 7. The block 9 is embedded in the notch 401 on the side of the fixed seat 4 and is used to limit the movement of the sliding seat 5 in one side direction.
[0022] In the middle of the fixed seat 4, two mutually parallel guide rails 402 are also installed, and the middle part of the sliding seat 5 slides along the guide rails 402; the middle part of the upper end of the sliding seat 5 is provided with an inverted trapezoidal groove;
[0023] The fixed seat 4 is integrally arranged in a rectangular structure, and its middle part is arranged in a hollow structure. The guide rails 402 are horizontally installed in this hollow structure. The sliding seat 5 can move horizontally along the guide rails 402 and the two side walls of the fixed seat 4. According to the size of the flame retardant board, the distance between the two groups of sliding seats 5 is appropriately adjusted. After the flame retardant board is placed in the middle of the upper end of the sliding seat 5, the two sides of the flame retardant board can be restricted from moving by cooperating with the limiting rod 8, so that the pressure sensor 3 can more conveniently apply pressure to the flame retardant board for detection.
[0024] The inner wall contour of the notch 401 is adapted to the outer wall contour of the stopper 9; a plurality of notches 401 are opened on both sides of the fixed seat 4. After the distance between the two groups of sliding seats 5 is adjusted, the stopper 9 can be inserted into the notch 401 close to the side of the two sliding seats 5 facing away from each other to limit the movement of the sliding seat 5 in one direction, so as to facilitate the hydraulic cylinder 2 to push the pressure sensor 3 to apply pressure to the flame retardant board for detection.
[0025] Through holes are opened at both ends of the limiting rod 8, and the limiting rod 8 is sleeved on the screw rod 6 through the through holes; after the flame retardant board is placed on the sliding seat 5, the limiting rod 8 can be placed on the screw rod 6 and locked by the nut 7. Preferably, two nuts 7 are arranged on the screw rod 6 to limit the upper and lower sides of the limiting rod 8.
[0026] Working principle: According to the size of the detected flame retardant board, push the two sliding seats 5 closer or farther away, then insert the stopper 9 into the notch 401 to limit the degree of freedom of the sliding seat 5 in one direction. Then place the flame retardant board on the two sliding seats 5 for support. Then place the limiting rod 8 on the screw rod 6 and lock the height of the limiting rod 8 by the nut 7. At this time, the limiting rod 8 can limit the two ends of the flame retardant board. Then drive the hydraulic cylinder 2 to push the pressure sensor 3 to move downward to apply pressure to the flame retardant board, and record the data transmitted by the pressure sensor 3 to realize the compressive resistance detection of the flame retardant board.
[0027] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
