[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In practical implementation: such as Figure 1-5 As shown, a spring wire elasticity testing device for Simmons mattresses includes:

[0022] Workbench 1, with a support frame 102 fixedly connected to the top of the workbench 1, a placement frame 101 fixedly connected to the surface of the workbench 1, a hydraulic push rod 103 provided on the top of the support frame 102, the output shaft of the hydraulic push rod 103 passing through the support frame 102 and fixedly connected to a pressure block 104, and a controller 2 provided on one side of the workbench 1.

[0023] Fixing component 3 is located inside the placement frame 101 and is used to fix the position of the spring steel wire.

[0024] The fixed component 3 includes a motor 301 installed inside the workbench 1. The output shaft of the motor 301 is fixedly connected to a gear 302. The gear 302 is coaxially arranged with the placement frame 101. Two symmetrically distributed racks 303 are meshed on the surface of the gear 302.

[0025] The spring steel wire is placed inside the placement frame 101. After its position is fixed by the fixing component 3, the hydraulic push rod 103 can drive the pressure block 104 to press down the spring steel wire to test the elasticity.

[0026] like Figure 1-5 As shown, a connecting plate 304 is fixedly connected to one end of the rack 303, and a support plate 312 is fixedly connected to the top of the connecting plate 304. The upper end of the support plate 312 passes through the workbench 1 and extends to the inner side of the placement frame 101. A slide rod 306 is slidably connected to the inner wall of the support plate 312. One end of the slide rod 306 passes through the support plate 312 and is fixedly connected to a fixing block 305.

[0027] A resistance-increasing block is fixedly connected to the bottom of the fixed block 305. The resistance-increasing block is a rubber material component.

[0028] A motor 311 is installed inside the connecting plate 304. The output shaft of the motor 311 is fixedly connected to a threaded rod 308. The upper end of the threaded rod 308 passes through the connecting plate 304, the support plate 312 and the slide rod 306 in sequence and is rotatably connected to the inner wall of the support plate 312. The slide rod 306 is threadedly connected to the surface of the threaded rod 308.

[0029] The inner wall of the support plate 312 is fixedly connected with two guide rods 309 that are symmetrically distributed, and the slide rod 306 is slidably connected to the surface of the guide rods 309.

[0030] By starting the motor 301, the gear 302 can be rotated, thereby causing the two meshing racks 303 to move synchronously. The two racks 303 move in opposite directions, which can drive the two support plates 312 to move away from each other synchronously through the connecting plate 304. During this process, the spring wire can move from the inside to the outside. Since the racks 303 move synchronously, the support plates 312 can be used to calibrate the position of the spring wire, so that it is located at the center of the placement frame 101, so that the force is more even during subsequent testing and the testing effect is improved.

[0031] The motor 311 can drive the threaded rod 308 to rotate, which in turn drives the slide rod 306 to move downward, so as to drive the fixed block 305 and the resistance block to move downward synchronously. This, in turn, works with the surface of the worktable 1 to fix the position of the spring wire. The rubber material component of the resistance block can increase the friction with the surface of the spring wire after fixing, avoiding the possibility of the spring wire being deformed and popping out under pressure during the testing process. The guide rod 309 can make the slide rod 306 more stable during the downward movement.

[0032] like Figure 1-5 As shown, a pressure sensor 307 is provided on the side of the support plate 312 away from the gear 302, and a buffer block 310 is provided on the surface of the pressure sensor 307. The other side of the buffer block 310 extends through the support plate 312.

[0033] During the movement of the support plate 312, the buffer block 310 first contacts the surface of the spring steel wire. As the support plate 312 moves, the spring steel wire applies pressure to the buffer block 310 and transmits the pressure to the pressure sensor 307. When the pressure sensor 307 detects that the pressure is greater than the preset value, it transmits the signal to the controller 2. The controller 2 shuts off the motor 301 to prevent the spring steel wire from deforming due to continued movement. At the same time, it starts the motor 311 to drive the threaded rod 308 to adjust the fixing block 305 and the resistance block to move down and fix the position of the spring steel wire.

[0034] In use, the spring steel wire is placed inside the placement frame 101 and its position is fixed by the fixing component 3. By activating the hydraulic push rod 103, the pressure block 104 can be driven to press down the spring steel wire for elasticity testing. During this process, the fixing component 3 can effectively improve the testing effect by fixing the spring steel wire, and can calibrate the position of the spring steel wire to make it located at the center of the placement frame 101, so that the force is more uniform in the subsequent testing process, improving the testing effect. At the same time, it can avoid the possibility of the spring steel wire deforming and popping out during the testing process.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
