[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Specific examples are given below.

[0031] like Figure 1-8 As shown, a multi-point pressure testing device for mattress production includes a pressure sensor body 1; the pressure sensor body 1 and a four-way signal amplifier 11 are connected by a signal; the four-way signal amplifier 11 and an STM32F103C8T6 minimum system board 12 are connected by a signal; the STM32F103C8T6 minimum system board 12 and a PC-side serial port assistant display tool 13 are connected by a signal; the pressure sensor body 1, the four-way signal amplifier 11, the STM32F103C8T6 minimum system board 12 and the PC-side serial port assistant display tool 13 are all connected in parallel; when working, The staff can install an appropriate amount of pressure sensor body 1 on the detection equipment, and check the pressure equipment to ensure that it can work normally. By setting up a four-way signal amplifier 11, the weak signal output by the pressure sensor body 1 can be amplified to reduce the test data fluctuation, thereby reducing the problem of insufficient pressure test point accuracy, and improving the signal strength and clarity. The set STM32F103C8T6 minimum system board 12 can improve the needs of various embedded applications and detection applications. At the same time, the use of the PC serial port assistant display tool 13 can increase the staff's intuitive understanding of the data, thereby improving the integrity and accuracy of the data.

[0032] like Figure 2 , 3, 4, 5 and 7, a receiving member 2 is fixedly connected to the middle of the pressure sensor body 1; a connecting member 21 is fixedly connected to the bottom of the receiving member 2, and the receiving member 2 and the connecting member 21 are connected; a plurality of drainage pipes 22 are fixedly connected to the bottom of the connecting member 21; a plurality of cooling grooves 23 are provided in the middle of the pressure sensor body 1, and the inner wall of the cooling groove 23 is fixedly connected to the drainage pipe 22; a heat conducting sheet 24 is fixedly connected to the middle of the pressure sensor body 1; a heat conducting rod 25 is fixedly connected to the end of the heat conducting sheet 24, and the heat conducting rod 25 passes through the connecting member 21. The inner wall of the heat-conducting rod 25 is slidably connected with a sliding block 26; the top of the sliding block 26 is fixedly connected with a cutter 27; the bottom wall of the storage member 2 is fixedly connected with a film 28, and the film 28 is arranged on the top of the cutter 27; when working, by providing a film 28 on the outer wall of the pressure sensor body 1, and injecting a proper amount of coolant into the inner wall of the storage member 2 in advance, the unfolded film 28 can block the coolant, and after the pressure sensor body 1 works for a long time and under high load, the gradually rising temperature on its surface will be blocked by the heat-conducting sheet 24 and the heat-conducting sheet 24. The rod 25 absorbs the volatile liquid, and when the temperature is higher than the volatile liquid stored on the inner wall of the heat-conducting rod 25, the liquid will vaporize and move upward as a whole against the light sliding block 26 until the middle of the cutter 27 gradually contacts the film 28. After the cutter 27 continues to rise, the middle of the film 28 can be punctured, and the liquid on the top of the film 28 flows to the middle of the connecting piece 21 and the multiple sets of drainage pipes 22 under the action of gravity until it is transferred to the inner wall of the multiple sets of cooling grooves 23, thereby taking away part of the heat of the entire surface of the pressure sensor body 1. This step cooperates with the set heat-conducting sheet 24 to discharge the coolant on the inner wall of the storage part 2 according to the temperature of the pressure sensor body 1, thereby improving the flexibility of the coolant when working. After the pressure sensor body 1 works under high load for a long time, the temperature is too high and the heat is difficult to dissipate, so that the pressure sensor body 1 and the internal circuit are damaged by high temperature. The liquid is transferred to the inner wall of the cooling groove 23 by cooperating with the multiple sets of drainage pipes 22, which can improve the area and efficiency of cooling the pressure sensor body 1.

[0033] like Figure 5 and 6As shown, a slide column 3 is slidably connected to the middle part of the storage part 2; a support rod 31 is fixedly connected to the bottom of the slide column 3; a float 32 is fixedly connected to the bottom of the support rod 31; a pull rod 33 is fixedly connected to the top of the slide column 3; two groups of springs 34 are fixedly connected to the end of the pull rod 33; a bell 35 is fixedly connected to the middle part of the spring 34; during operation, a slidable slide column 3 is provided in the middle part of the storage part 2, and after a proper amount of coolant is poured into the inner wall of the storage part 2, the float 32 can be suspended on the top of the coolant under the action of buoyancy, and the slide column 3 can block the liquid inlet in the middle part of the storage part 2, and when the coolant on the inner wall of the storage part 2 flows out, the float 32 will drop synchronously, and the two groups of bells 35 will gradually approach The bell 35 is moved close to the top of the storage part 2 until they are in contact with each other, and the spring 34 is provided to change the twisting angle of the bell 35, and the bell 35 can make a sound when contacting the top of the storage part 2. This step is carried out in conjunction with the sliding column 3 provided to seal the middle part of the storage part 2, thereby reducing the entry of some external impurities into the storage part 2, so that the subsequent storage part 2 will not be stuck when discharging the coolant, and the bell 35 can be used to remind the staff that the overall temperature of the pressure sensor body 1 is overheated and reduce the problem of damage to the pressure sensor body 1 due to continuous high temperature. Under the action of the spring 34, the frequency of the shaking of the bell 35 can be increased.

[0034] like Figure 7 As shown, the bottom wall of the storage member 2 is fixedly connected to a support plate 4; the middle part of the support plate 4 is fixedly connected to a limit frame 41; the inner wall of the support plate 4 is fixedly connected to two groups of first magnets 42; the side wall of the cutter 27 is fixedly connected to two groups of second magnets 43, and the second magnets 43 and the first magnets 42 are arranged to attract each other; when working, by arranging the support plate 4 and the limit frame 41 on the top of the film 28, when the sliding block 26 as a whole moves upward under the action of air pressure, the two groups of second magnets 43 will gradually approach the position of the first magnet 42 and generate relative suction, and after the two reach a certain distance, the first magnet 42 and the second magnet 43 will be adsorbed together, and the sliding block 26 will move upward quickly, and under the action of the limit frame 41, the raised cutter 27 will cut and damage the middle part of the film 28. In this step, under the action of the second magnet 43 and the first magnet 42 being adsorbed together, the accuracy of the middle part of the film 28 being broken by the cutter 27 can be improved, and the problem of sufficient air pressure inside the heat conducting rod 25 lasting for a long period of time can be reduced. Under the action of the limit frame 41, the problem of the film 28 bulging upward due to the lack of a limiting device after the cutter 27 comes into contact with the film 28 can be reduced.

[0035] like Figure 3 and 4As shown, a frame plate 5 is fixedly connected to the middle of the pressure sensor body 1; a sponge 51 is fixedly connected to the inner wall of the frame plate 5, and the sponge 51 is arranged at the bottom of the multiple groups of cooling grooves 23; a baffle 52 is fixedly connected to the middle of the pressure sensor body 1, and the middle part of the baffle 52 is arranged in an arc shape; when working, by arranging a frame plate 5 in the middle of the pressure sensor body 1, when the coolant is discharged from the edge of the cooling groove 23, it will be absorbed by the sponge 51 in the internal position and blocked by the frame plate 5, and at the same time, the arc-shaped baffle 52 can block the external dust. This step cooperates with the sponge 51 to collect the discharged coolant, reduce the problem of flowing at the bottom of the pressure sensor body 1, and make the subsequent maintenance troublesome, and at the same time, under the action of the baffle 52, the surface cleanliness of the sponge 51 when it is placed can be improved.

[0036] like Figure 7 As shown, two groups of connecting ropes 6 are fixedly connected to the middle part of the sliding block 26; the ends of the connecting ropes 6 are fixedly connected to the counterweights 61; during operation, two groups of connecting ropes 6 are arranged on the inner wall of the sliding block 26, so that the connecting ropes 6 can fix the position of the counterweights 61, and when the sliding block 26 is moving, under the action of inertia, the counterweights 61 can collide with the inner wall of the heat-conducting rod 25. In this step, under the action of the impact, the dust and impurities at the connection between the heat-conducting rod 25 and the sliding block 26 can be cleaned, thereby reducing the problem of large resistance when the subsequent 265 is working, which makes maintenance troublesome.

[0037] like Figure 5 and 8 As shown, the torsion spring at the top of the storage member 2 is connected to two groups of rotating rods 7; a top plate 71 is fixedly connected to the middle of the rotating rod 7, and the top plate 71 is arranged at the bottom of the pull rod 33; when working, two groups of inclined rotating rods 7 are arranged on the top of the storage member 2, and the bell 35 can squeeze the rotating rod 7 and the top plate 71 to move after approaching the top plate 71, and push the bell 35 and the spring 34 to deform. Under the action of the inclined top plate 71, this step can increase the deformation amplitude of the middle part of the spring 34, thereby increasing the frequency and vibration amplitude of the bell 35 when shaking, and further improving the staff's recognition accuracy of the sound generated by the bell 35.

[0038] like Figure 6 As shown, a top block 8 is fixedly connected to the middle of the support rod 31, and the middle of the top block 8 is arranged in an arc shape; during operation, by arranging the top block 8 in the middle of the support rod 31, when liquid needs to be added to the storage part 2 again later, the staff can pull the pull rod 33 upwards, and make the support rod 31 contact the inner wall of the liquid inlet at the top of the storage part 2, and inject liquid from the gap between the two. This step cooperates with the arrangement of the top block 8 to improve the accuracy of subsequent liquid injection and limit the distance between the float 32 and the inner wall of the storage part 2.

[0039] like Figure 6 As shown, a friction member 9 is fixedly connected to the middle of the pull rod 33; during operation, by providing the friction member 9 in the middle of the pull rod 33, the subsequent staff can deeply contact the friction member 9 when holding the pull rod 33. This step cooperates with the friction member 9 to improve the stability when pulling the pull rod 33 and reduce the problem of slipping caused by excessive sweat on the hands.
