[0031] 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.

[0032] Example 1

[0033] Please see Figures 1 to 8This utility model provides a technical solution: a cylinder cover seal ring tensile testing mechanism, including a tensile testing device for testing cylinder cover seal ring A, comprising a base 11, a frame beam 12 mounted on the base 11, and a clamping moving arm 13 mounted between opposing surfaces of the frame beam 12. The cylinder cover seal ring A is mounted between the clamping moving arm 13 and the clamp on the frame beam 12. The clamping moving arm 13 moves vertically, causing the cylinder cover seal ring A to stretch, thus measuring the tensile performance of the cylinder cover seal ring A. The testing principle and structure of the testing machine are conventional technologies, and will not be described in detail in this application. A shielding mechanism includes a fixed plate 2 connected to the frame beam 12, a moving plate 3 slidably connected to the fixed plate 2, and a connecting piece connecting the fixed plate 2 and the moving plate 3. The fixed plate 2 and the moving plate 3 are mounted on the frame beam 11. On the outside of plate 2, fixed plate 2 and movable plate 3 cover the gantry-shaped beam 12 to prevent dust and dirt from adhering to the inner surface of beam 12. Fixed plate 2 is connected to beam 12 by screws. The connecting component includes a limiting rod 33 installed on movable plate 3 and a limiting block 32 installed on fixed plate 2 and slidably connected to limiting rod 33. Limiting block 32 is connected to fixed plate 2 by screws. Movable plate 3 is provided with a toggle bar 31. Movable plate 3 and limiting rod 33 are screwed together. Movable plate 3 and limiting rod 33 slide horizontally in a straight line. Limited by limiting block 32, the sliding of movable plate 3 is stable. When movable plate 3 slides horizontally, toggle bar 31 pushes pull member 61 to slide in a straight line along the length of fixed rod 62, thereby pulling pull rope 55. A stabilizing plate 4 is installed on the inner wall of the fixed plate 2. The stabilizing plate 4 is connected to the fixed plate 2 by screws. The stabilizing plate 4 is provided with a fixing ring 42 and a suspension component. The stabilizing plate 4 is connected to the fixing ring 42 by screws. The suspension component includes a rotating rod 51 that passes through the stabilizing plate 4, a rotating plate 52 that is perpendicularly connected to one end of the rotating rod 51, and a suspension rod 53 installed on the rotating plate 52. The rotating rod 51 is rotatable. The rotating plate 52 is connected to the rotating rod 51 and the suspension rod 53 by screws. The cylinder cover seal ring A is suspended on the suspension rod 53. When the rotating rod 51 rotates, the rotating plate 52 and the suspension rod 53, which are in the retracted state, are opened to the horizontal state, exposing the cylinder cover seal ring A. This facilitates the selection of a new cylinder cover seal ring A for the next tensile test. The components are placed on the suspension rod 53 for easy operation; the pulling assembly includes a fixed rod 62 installed inside the stabilizing plate 4, a pulling member 61 slidably sleeved on the fixed rod 62, a coil spring 56 installed inside the fixed ring 42, a pulling rod 54 extending through the fixed ring 42 at one end of the vertical rotating rod 51, and a pulling rope 55 installed between one end of the pulling rod 54 and the pulling member 61. The fixed rod 62 is connected to the stabilizing plate 4 by a threaded connection. The pulling member 61 slides along the straight direction of the fixed rod 62. When the pulling member 61 is pulled, the pulling rope 55 is pulled, and the pulling rope 55 pulls the pulling rod 54 and the rotating rod 51 to rotate. The coil spring 56 is in a contracted state and generates a rebound force to return to its original position. The rotating rod 51 drives the rotating plate 52 and the suspension rod 53 to rotate.

[0034] In this embodiment, the limiting block 32 has a "T" shaped structure, and the limiting rod 33 is provided with a limiting groove b that cooperates with the limiting block 32. The moving plate 3 and the limiting rod 33 slide horizontally in a straight line. The limiting block 32 limits the moving plate 3 to slide smoothly.

[0035] In this embodiment, the suspension rod 53 has a "T" shaped structure, and the fixing ring 42 is provided with an arc-shaped groove for the pull rod 54 to rotate 90 degrees. The fixing ring 42 restricts the pull rod 54 so that it slides in a predetermined direction without deflection.

[0036] In this embodiment, the two ends of the coil spring 56 are connected to the inner surface of the fixed ring 42 and one end of the rotating rod 51, respectively. The distance between the pulling rod 54 and the coil spring 56 is 5 mm. The coil spring 56 does not affect the rotation of the pulling rod 54. Both the coil spring 56 and the pulling rod 54 are connected to one end of the rotating rod 51.

[0037] In this embodiment, the fixing rod 62 is a hollow square rod structure. The pulling member 61 includes a ring part and a round rod part. The ring part is slidably sleeved on the outside of the fixing rod 62. The ring part has a square groove inside, and the inner surface of the ring part located in the square groove has a fixing hemisphere 611 that is tangent to the outer surface of the fixing rod 62. The fixing hemisphere 611 is bonded to the inner surface of the pulling member 61 with glue. The friction between the fixing hemisphere 611 and the outer surface of the fixing rod 62 is small and does not affect the sliding of the pulling member 61. The pulling member 61 slides smoothly along the length direction of the fixing rod 62.

[0038] In this embodiment, the interior of the stabilizing plate 4 is provided with a vertical guide rod 41. The guide rod 41 is connected to the stabilizing plate 4 by a threaded connection. The pulling rope 55 passes around the fixing ring 42 and the outer surface of the guide rod 41. The pulling rope 55 is guided by the fixing ring 42 and the guide rod 41, so that the pulling rope 55 is in a taut state, which is conducive to the pulling rope 55 pulling the pulling rod 54, causing the pulling rod 54 to rotate.

[0039] In summary: the fixed plate 2 and the movable plate 3 cover the gantry-shaped beam 12, preventing dust and dirt from adhering to the inner surface of the beam 12. The cylinder cover sealing ring A sample can be suspended on the suspension rod 53. When the movable plate 3 is opened, the actuating bar 31 moves the pulling member 61, and the pulling member 61 moves along the length of the fixed rod 62. The pulling rope 55 pulls the pulling rod 54, causing the pulling rod 54, the rotating rod 51, the rotating plate 52, and the suspension rod 53 to rotate 90 degrees, exposing the cylinder cover sealing ring A sample for easy access.

[0041] Please see Figures 1 to 10This is the second embodiment of the present invention. Based on the previous embodiment, in order to increase the storage effect, the fixing plate 2 has a right-angle structure. The side of the fixing plate 2 is provided with a storage component. The storage component includes a box body 71 connected to the fixing plate 2 and a box cover 72 hinged to the box body 71. The box body 71 and the fixing plate 2 are connected by screws. The box body 71 has a storage cavity inside. The box body 71 is horizontally installed inside the storage cavity. The storage plate 73 is connected to the box body 71 by screws. Tools and other items used in the testing process can be placed on the storage plate 73. The storage plate 73 has a right-angle structure. A baffle c is provided on one end of the storage plate 73. A restraining strap 731 is provided between the box body 71 and the baffle c. The restraining strap 731 serves to restrain the placed items.

[0042] In summary: the shelf 73 can hold tools and other items used in the testing process, the restraint strap 731 serves to restrain the placed items, and the box body 71 and the lid 72 have storage space for items used in the testing of cylinder cover sealing ring A.
