A protective mechanism 20 is provided outside the damper testing machine body 10. The protective mechanism 20 includes a set of slide rails 201 respectively arranged on the front and rear sides of the damper testing machine body 10. On the right side of the tops of the two sets of slide rails 201, a first protective shell 202 is provided. The bottom of the first protective shell 202 is rollingly connected to the two innermost slide rails 201 through two sets of sliding wheels 205; on the left side of the first protective shell 202, a second protective shell 203 is provided. The bottom of the second protective shell 203 is rollingly connected to the middle slide rail 201 through two sets of sliding wheels 205; on the left side of the second protective shell 203, a third protective shell 204 is provided. The bottom of the third protective shell 204 is rollingly connected to the outermost slide rail 201 through two sets of sliding wheels 205. The above-mentioned sliding wheels 205 are rollingly connected to the slide rails 201, so as to achieve the effect of guiding the movement of the protective shell.

[0026] Preferably, sliding grooves 206 are opened on the front and rear sides inside the second protective shell 203. The left ends of the front and rear sides of the first protective shell 202 are respectively fixedly connected with sliding blocks 207. The sliding blocks 207 are slidably connected to the sliding grooves 206; sliding grooves 206 of the same kind are opened on the front and rear sides inside the third protective shell. The left ends of the front and rear sides of the second protective shell 203 are respectively fixedly connected with sliding blocks 207. The sliding blocks 207 are slidably connected to the sliding grooves 206. The above three protective shells can be folded and unfolded through sliding connection. When folded, it does not occupy space and is convenient for checking the damper testing machine body 10 before the experiment; when unfolded, it forms a longer whole to cover the top of the damper testing machine body 10, preventing the test pieces from scattering during the test of the damper testing machine body 10. A positioning mechanism 30 is provided on the right side of the sliding groove 206.

[0027] Preferably, the first protective shell 202, the second protective shell 203, and the third protective shell 204 are all made of transparent tempered glass material, which has high strength and is convenient for the staff to observe the working process of the damper testing machine body 10.

[0028] Reference Figure 1 , 4 As shown in FIGS. 4 and 5, the positioning mechanism 30 includes a docking groove 301 opened on the right side of the sliding block 207. Positioning grooves 302 are opened on the front and rear sides of the docking groove 301; the positioning mechanism 30 further includes an insertion block 303 fixedly connected to the left side inside the sliding groove 206. A pair of clamping blocks 304 are respectively fixedly connected to the front and rear sides of the left end of the insertion block 303. A rotatable positioning piece 305 is rotatably connected to the inside of the same-side pair of clamping blocks 304 through a movable shaft.

[0029] Specifically, the front and rear sides of the insertion block 303 are respectively fixedly connected with a support spring 306 and an outer positioning piece 305 of the support spring 306; a movable groove 307 is opened inside the insertion block 303, and a movable rod 308 is slidably connected inside the movable groove 307, and the movable rod 308 extends to the right and passes through the sliding groove 206; the front and rear sides of the movable groove 307 are respectively opened with active grooves 309, and the front and rear sides of the movable rod 308 are respectively fixedly connected with a pulling rope 310, the pulling rope 310 passes through the active groove 309, and the outer end of the pulling rope 310 is fixedly connected to the positioning piece 305.

[0030] Preferably, the positioning piece 305 is designed to be gradually longer from left to right in an arc shape; when the three protective shells are pulled to the left, the right side surface of the first protective shell 202 first contacts the right side of the damper test machine body 10, thereby achieving the effect of preliminary positioning of the protective mechanism 20, and then continue to pull the second protective shell 203 and the third protective shell 204 to the left until the two corresponding sliding blocks 207 move to the end of the sliding groove 206, thereby achieving the effect of full deployment, and in this process, the docking groove 301 is plugged into the insertion block 303, and during the plugging process, the contact force drives the positioning pieces 305 on both sides to flip inward, and at the same time compresses the support spring 306, until the insertion block 303 is fully inserted into the docking groove 301, the positioning groove 302 corresponds to the position of the positioning piece 305, so that the support spring 306 rebounds and drives the positioning piece 305 to flip outward and press against the inside of the positioning groove 302, thereby achieving the fixing effect of the protective mechanism 20 after deployment, thereby forming a fixed whole to protect the damper test machine body 10.

[0031] Preferably, a return spring 311 is fixedly connected to the inner side of the docking groove 301; after the insertion block 303 is fully inserted into the docking groove 301, the return spring 311 is compressed. When the protective mechanism 20 needs to be folded, the moving rod 308 is first pulled outward, and the moving rod 308 moves through the pulling rope 310 to drive the two positioning pieces 305 to flip inward and disengage from the positioning groove 302, so that the return spring 311 rebounds to push the sliding block 207 out of the end of the sliding groove 206.

[0032] refer to Figure 1 , 3 A merging mechanism 40 is installed on the top of the third protective shell 204, and the merging mechanism 40 includes a pair of mirror-symmetrical storage blocks 401 fixedly connected to the front and rear sides of the top of the third protective shell 204, and a pair of storage blocks 401 are provided with storage grooves 402 on opposite sides. A rotating rod 404 is provided at the left end of the inner part of the storage groove 402, and the rotating rod 404 is fixedly connected with a roller 403 through the front and rear sides. The roller 403 is rollingly connected to the corresponding storage groove 402, and a merging plate 405 is rotatably connected to the rotating rod 404.

[0033] After the protection mechanism 20 is deployed, pull the merging plate 405 to the left. The merging plate 405 drives the rotating rod 404 to move in the same direction, and drives the roller 403 to roll along the inside of the storage groove 402 until the rotating rod 404 moves to the leftmost side of the storage groove 402, and then flip the merging plate 405 downward so that the merging plate 405 covers the left side of the third protective shell 204, thereby achieving the protection of the entire outer surface of the damper testing machine body 10. At the same time, the flipped merging plate 405 can be fixed to the outside of the third protective shell 204 through components such as bolts. Similarly, the merging plate 405 can be stored on the top of the third protective shell 204 in the opposite way described above, so as to facilitate the folding of the protection mechanism 20 together.

[0034] The working principle of the present utility model is as follows: When in use, pull the three protective shells to the left. The right side of the first protective shell 202 first contacts the right side of the damper testing machine body 10, thereby achieving the initial positioning effect of the protection mechanism 20. Then continue to pull the second protective shell 203 and the third protective shell 204 to the left until the two corresponding sliding blocks 207 move to the ends of the sliding grooves 206, thereby achieving the fully deployed effect. And during this process, the docking groove 301 is inserted into the insertion block 303. During the insertion process, the contact force drives the two side positioning pieces 305 to flip inward, and at the same time compresses the support spring 306. Until the insertion block 303 is completely inserted into the docking groove 301, the positioning groove 302 corresponds to the position of the positioning piece 305, so that the support spring 306 rebounds and drives the positioning piece 305 to flip outward and abut against the inside of the positioning groove 302, thereby achieving the fixing effect after the protection mechanism 20 is deployed, and thus forming a fixed whole to protect the damper testing machine body 10.
