[0024] 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.
[0025] In practical implementation: such as Figures 1-5 As shown, a spring tensile strength testing device includes: a base 100, a controller 200 and a cylinder 210. The controller 200 is disposed on one side of the base 100 and the cylinder 210 is disposed above the base 100.
[0026] The protective mechanism 300 includes two protective shells 310 rotatably connected to the base 100. Inside the protective shell 310, there is a push rod 320 connected to the cylinder 210. An adjusting rod 331 is provided between the push rod 320 and the protective shell 310. The bottom end of the push rod 320 is fixedly connected to an upper clamping block 321.
[0027] After the cylinder 210 is started by the controller 200, the controller 200 can detect the pressure change inside the cylinder 210, thereby calculating the pressure applied to the push rod 320, indirectly calculating the tension of the upper clamping block 321 on the spring, and displaying it on the display screen of the controller 200 so that the staff can record it in real time.
[0028] like Figure 1 , Figure 2 and Figure 3As shown in the drawings, the surface of the push rod 320 is fixedly connected with a connecting block 330, the inner wall of the protective shell 310 is oppositely provided with two sliding grooves 333, the sliding grooves 333 are slidably connected with sliding blocks 332, the two ends of the two adjusting rods 331 are respectively hinged to the sliding blocks 332 and the connecting block 330, the upper surface of the base 100 is fixedly connected with a support 110, the air cylinder 210 is fixedly connected to the middle of the support 110, the push rod 320 penetrates out of the protective shell 310 and is connected with the air cylinder 210, the protective shell 310 is in an inverted "8" shape, and the opposite two surfaces of the protective shell 310 are provided with tempered glass 311.
[0029] In the embodiment, the middle of the bottom end of the protective shell 310 is rotatably connected with a rotating shaft, the rotating shaft is fixed to the surface of the base 100, the surface of the base 100 is provided with an arc-shaped slot for the rotation of the protective shell 310, and the bottom end of the protective shell 310 is provided with a circular opening for the movement of the push rod 320.
[0030] As shown in the drawings, Figure 3 , Figure 4 and Figure 5 , the middle of the base 100 is fixedly connected with a lower clamping block 340, the middle of the lower clamping block 340 is provided with a fixed groove 344, the fixed groove 344 is annular, the upper side of the fixed groove 344 is provided with a clamping plate 341, the two ends of the clamping plate 341 are provided with threaded rods 342, the threaded rods 342 extend to the inner wall of the lower clamping block 340, the surface of the lower clamping block 340 is fixedly connected with a limiting hook 343, and the limiting hook 343 is an arc-shaped block. When installing the spring, the lower clamping block 340 needs to be raised through the threaded rods 342 first, then the last circle of the spring is placed in the fixed groove 344 while passing through the limiting hook 343, then the threaded rods 342 are rotated, the clamping block is driven downward, and the bottom end of the spring is fixed in the limiting groove.
[0031] When the device is used for the first time, the force required for the air cylinder 210 to pull the protective shell 310 to close and open needs to be tested first, and then recorded, and when the spring is detected, the force required for closing the protective shell 310 is subtracted from the force required for pulling the spring;
[0032] When the spring is detected, the bottom end of the spring needs to be placed in the fixed groove 344 first, then the clamping plate 341 is lowered by rotating the threaded rods 342, the bottom end of the spring is fixed in the limiting groove, then the spring passes through the limiting hook 343 and the top end thereof is fixed with the upper clamping block 321, and then the air cylinder 210 is started through the controller 200.
[0033] The cylinder 210 drives the push rod 320 to move upward and pull the upper clamp block 321, and the upper clamp block 321 pulls the top end of the spring. The push rod 320 moves upward and drives the connecting block 330 to move upward. The connecting block 330 moves upward and first drives the two adjusting rods 331 to rotate upward and makes the sliding block 332 move upward along the sliding groove 333, and drives the protective shell 310 to close. At this time, the worker can observe the change of the spring through the toughened glass 311 and combine the data displayed by the controller 200. When the spring reaches the preset stretching distance, the controller 200 is operated to drive the cylinder 210 to drive the push rod 320 to move downward. When the push rod 320 moves downward, the connecting block 330 will descend synchronously, and the sliding block 332 will slide downward along the sliding groove 333, and the adjusting rod 331 will slightly rotate. When the sliding block 332 slides to one end of the sliding groove 333, the sliding block 332 will not be able to move. At this time, the connecting block 330 continues to descend, so that the protective shell 310 is completely opened, and then the worker can take out the spring.
[0034] It should be noted that the cylinder 210 and the threaded rod 342 in the above description are relatively mature devices in the prior art, and the specific model can be selected according to actual needs.

The description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
