Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described 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.

[0021] Please refer to Figures 1 to 10 As shown, embodiment 1: The present invention provides a modular shield door performance test device, including a frame assembly 1, the frame assembly 1 includes a test seat 101, a mounting frame 102 and an electric push rod 103, the mounting frame 102 is fixedly mounted on the top of the test seat 101, and the electric push rod 103 is fixedly mounted on the top of the mounting frame 102; the test assembly is also included, and the test assembly is composed of an energy storage mechanism 2 and an impact mechanism 3; The energy storage mechanism 2 includes a follower seat 201, a positioning disk 202 and an adjusting rod 203. The follower seat 201 is fixedly mounted on the bottom end of the push rod of the electric push rod 103, and the positioning disk 202 is inserted into the inside of the follower seat 201, and the adjusting rod 203 is rotatably connected to the inside of the follower seat 201; the impact mechanism 3 includes a transmission seat 301, an action block 302, a trigger block 303 and a retaining block 304. The transmission seat 301 is inserted into the bottom of the follower seat 201, and the bottom of the transmission seat 301 is detachably fixedly installed with a test pad 4, the action block 302 is inserted into the inside of the transmission seat 301, and the trigger block 303 is vertically inserted into the inside of the action block 302, the retaining block 304 is horizontally inserted into the inside of the action block 302, and the adjusting rod 203 is located directly above the trigger block 303.

[0022] In the embodiment of the present disclosure, a track rod 3022 is provided on the top of the action block 302, and a track groove 2021 is provided inside the positioning plate 202. The track rod 3022 is inserted into the inside of the track groove 2021. There are two track rods 3022, and the two track rods 3022 are symmetrically arranged on the top of the action block 302. This design makes the positioning plate 202 only move in a straight line inside the follower seat 201 and cannot rotate, which facilitates the adjustment operation of the test force.

[0023] The locking cam 303 is pressed against the locking cam 304 at the bottom and the locking cam 304 is pressed against the bottom of the locking cam 303 at the bottom. The holding block 304 is inserted into the inside of the retaining slot 3011, the rod body of the track rod 3022 passes through the top of the follower seat 201, and the top of the track rod 3022 is provided with a reset block 3023, the block outer diameter of the reset block 3023 is larger than the rod outer diameter of the track rod 3022, and the reset block 3023 abuts against the top of the follower seat 201, and under the action of the reset block 3023 and the impact top spring 3021, the follower seat 201 and the transfer seat 301 are at the maximum distance and the two are maintained as a whole. When the electric push rod 103 is extended and retracted, it can drive the follower seat 201 and the transfer seat 301 to move synchronously without changing the distance between the two, thereby facilitating the test pad 4 at the bottom of the transfer seat 301 to abut against the shielding door for impact performance testing, which is convenient and flexible to use.

[0024] In the embodiment of the present disclosure, an impact top spring 3021 is provided on the top of the action block 302, and the two ends of the impact top spring 3021 respectively abut against the top of the action block 302 and the inside of the follower seat 201. In use, when the test pad 4 abuts against the shielding door, the electric push rod 103 is controlled to continue to extend to complete the power storage and impact test of the shielding door. Since the test pad 4 is blocked by the shielding door and cannot continue to move with the follower seat 201, the transfer seat 301 cannot continue to move with the follower seat 201. Since the retaining block 304 is inserted into the inside of the retaining slot 3011, the action block 302 will not change its position in the initial stage of the test. The position inside the transfer seat 301, thereafter, when the follower seat 201 continues to move downward, it can compress the impact spring 3021 to store energy. As the follower seat 201 continues to move downward, the adjustment rod 203 inside it will conflict and squeeze the trigger block 303. After being conflicted and squeezed, the trigger block 303 can move downward inside the action block 302 and compress the holding spring 3031. A linkage groove 3032 is provided on the side of the trigger block 303, and a linkage rod 3041 is provided inside the holding block 304. The groove body of the linkage groove 3032 is inclined, and the linkage rod 3041 is inserted into the inside of the linkage groove 3032. When the trigger block 303 moves, the linkage groove 3032 can drive the holding block 304 to retract into the inside of the action block 302 through the linkage rod 3041, so that the holding block 304 can be disengaged from the inside of the holding slot 3011, so that the action block 302 can release the positioning relationship inside the transfer seat 301. Thereafter, under the action of the impact top spring 3021, the action block 302 will fall quickly to impact the transfer seat 301, and the transfer seat 301 can transmit the impact force to the test pad 4, thereby realizing the impact performance test operation of the shielding door. It is convenient and flexible to use. After a single test is completed, the test assembly can be reset by retracting the electric push rod 103. When the electric push rod 103 retracts When the cam 301 is in the closed position, the cam 302 is in the closed position, and ...

[0025] In the embodiment of the present disclosure, the outside of the rod body of the adjusting rod 203 is provided with a thread, and the adjusting rod 203 is screwed to the inside of the positioning plate 202 through the rod body thread. During use, the impact force of the test assembly can be adjusted by the adjusting rod 203, so as to adapt to different test requirements of the impact performance of the shielding door. When the adjusting rod 203 is rotated, the adjusting rod 203 can drive the positioning plate 202 to the use position inside the follower seat 201 through the rod body thread. The change of the use position of the positioning plate 202 changes the initial extension length of the impact top spring 3021 and the maximum compression length of the impact top spring 3021 during the test, that is, changes the impact force of the test. It is easy to adjust and has strong adaptability.

[0026] Specific usage and function of this embodiment: In the present invention, according to actual test requirements, the impact force of the test component during the test is adjusted. The impact force of the test component can be adjusted by the adjusting rod 203, so as to adapt to different test requirements of the impact performance of the shielding door. When the adjusting rod 203 is rotated, the adjusting rod 203 can drive the positioning plate 202 to the use position inside the follower seat 201 through the rod body thread. The change of the use position of the positioning plate 202 changes the initial telescopic length of the impact top spring 3021 and the maximum compression length of the impact top spring 3021 during the test, that is, changes the impact force of the test. The electric push rod 103 can drive the test component to rise and fall, thereby realizing the shielding door placed on the test seat 101. The door is subjected to impact performance test, which is convenient and flexible to use. In the reset state, the lower half of the transfer seat 301 is extended out of the interior of the follower seat 201 under the action of gravity. Under the action of the holding spring 3031, the retaining block 304 is inserted into the interior of the retaining slot 3011. Under the action of the reset block 3023 and the impact spring 3021, the follower seat 201 and the transfer seat 301 are at the maximum distance and the two are maintained as a whole. When the electric push rod 103 is extended and retracted, it can drive the follower seat 201 and the transfer seat 301 to move synchronously without changing the distance between the two, thereby facilitating the impact performance test of the transfer seat 301 against the shielding door. When the test pad 4 is in contact with the shielding door After the shielding door is on, the electric push rod 103 is controlled to continue to extend to complete the force storage and impact test of the shielding door. Since the test pad 4 is blocked by the shielding door and cannot continue to move with the follower seat 201, the transfer seat 301 cannot continue to move with the follower seat 201. Since the retaining block 304 is inserted into the retaining slot 3011, the action block 302 will not change its position inside the transfer seat 301 at the initial stage of the test. Thereafter, when the follower seat 201 continues to move downward, it can press the impact top spring 3021 to store energy. As the follower seat 201 continues to move downward, the adjusting rod 203 inside it will conflict with and squeeze the trigger block 303. After being conflicted and squeezed, the trigger block 303 can move downward inside the action block 302 and After the cam 303 is released, the locking cam 304 is released from the locking cam 3011, and the locking cam 302 is released from the locking cam 301. After that, the locking cam 302 is released from the locking cam 301, and the locking cam 302 is released from the locking cam 301. The locking cam 302 is released from the locking cam 301, and the locking cam 302 is released from the locking cam 301. The locking cam 302 is released from the locking cam 301, and the locking cam 302 is released from the locking cam 301.When the follower seat 201 moves upward, it can drive the action block 302 to move upward inside the transfer seat 301 by resisting the reset block 3023 until the retaining block 304 inside the action block 302 moves to the position of the retaining slot 3011. Under the action of the retaining spring 3031, the retaining block 304 will be re-inserted into the retaining slot 3011, thereby restoring the transfer seat 301 and the follower seat 201 to the state of maximum use distance. After that, when the follower seat 201 continues to move upward, it can drive the entire test assembly to move upward for the next test.

[0027] In another embodiment, the bottom cross-section of the test pad 4 may be conical or semicircular, so as to adapt to the testing requirements of different types of impacts, further improving the adaptability of the device.
