[0002] The elevator floor door is a safety facility that connects the elevator shaft and the corridor. Its firmness and safety directly affect the safe operation of the elevator. The elevator floor door strength test, that is, the elevator floor door impact test, is an important part of the elevator safety inspection process, which aims to ensure the firmness of the elevator floor door and whether it can withstand external force impact.

[0003] At present, when conducting impact tests, staff often use an impact test device, which has a square frame and a suspended impact hammer. When in use, the staff manually pulls the impact hammer to a high place, and then releases the impact hammer to let the impact hammer slide down under the action of gravity and impact the elevator floor door. However, when the impact hammer is manually pulled, since there are no limits on the left and right sides of the impact hammer, the impact hammer is easy to deviate from the center of the frame during the process of being pulled to the release position. If the impact hammer is released in a displaced state, its final impact point will also be displaced, affecting the test results. Therefore, it is urgent to design an elevator floor door strength detection device to solve the above problems. Utility Model Content

The impact hammer 2 is suspended on the top of the frame 1, the two arc-shaped guide rods 3 are symmetrically fixedly installed in the frame 1, and the clamping assembly 4 is slidably installed between the two arc-shaped guide rods 3.

[0023] The clamping assembly 4 includes two round rods 401, a strip plate 402, two slide rods 404 and two clamping plates 405. The two round rods 401 are respectively slidably installed in the two arc guide rods 3, the strip plate 402 is fixedly installed between the two round rods 401, a strip groove 403 is opened between the two sides of the strip plate 402, the two slide rods 404 are symmetrically slidably installed in the strip groove 403, and the two clamping plates 405 are respectively fixedly installed at one end of the two slide rods 404 close to each other, and the clamping plate 405 is adapted to the impact hammer 2.

[0024] Specifically, the two arc-shaped guide rods 3 are each provided with a slide groove 5 , and the two round rods 401 are slidably installed in the two slide grooves 5 .

[0025] Specifically, the clamping assembly 4 also includes two connecting rods 406, a pull rod 407 and a gripping rod 408. The two connecting rods 406 are rotatably installed in the sliding rod 404 respectively, the pull rod 407 is installed between the two connecting rods 406, and the two connecting rods 406 are rotatably connected to the pull rod 407. The gripping rod 408 is fixedly installed on one side of the strip plate 402.

[0026] Specifically, the clamping assembly 4 further includes a fixing rod 410 , which is fixedly installed in the strip groove 403 , and the two sliding rods 404 are both slidably sleeved on the outer wall of the fixing rod 410 .

[0027] In this embodiment, the fixed rod 410 is provided to provide support for the two sliding rods 404, so that the two sliding rods 404 can stably slide in the strip groove 403 when being pulled.

[0028] Specifically, the clamping assembly 4 further includes a fixing piece 411, two springs 412 and two push pieces 413. The fixing piece 411 is fixedly mounted in the middle of the strip groove 403, the two springs 412 are respectively fixedly mounted at both ends of the fixing piece 411, the two push pieces 413 are respectively fixedly mounted at one end of the two springs 412 that are away from each other, and the two push pieces 413 are respectively in contact with the two slide bars 404.

[0029] In this embodiment, in the initial state, the two springs 412 are in a released state, and push the two slide bars 404 and the two clamping plates 405 away from each other through the two pushing pieces 413 .

[0030] Specifically, the clamping assembly 4 further includes a plurality of anti-slip strips 409 , which are equidistantly distributed on the outer walls of the pull rod 407 and the grip rod 408 circumferentially.

[0031] In this embodiment, the anti-slip strip 409 is provided to increase the friction between the pull rod 407 and the grip rod 408 and the staff's hands, thereby improving the stability of the staff when holding.

[0032] Specifically, the clamping assembly 4 further includes two limiting rings 414 , and the two limiting rings 414 are respectively fixedly mounted on the outer walls of the two round rods 401 .

[0034] Working principle: When in use, first hold the grip 408, adjust the two clamps 405 to the two sides of the impact hammer 2, then hold the grip 408 while holding the pull rod 407, and pull the pull rod 407. At this time, the pull rod 407 will drive the two connecting rods 406 to approach each other, and the two connecting rods 406 approaching each other will drive the two sliding rods 404 to approach each other, thereby driving the two clamps 405 to clamp the impact hammer 2. The sliding of the two sliding rods 404 will also compress the two springs 412. Then continue to pull the pull rod 407 and the grip 408, drive the strip plate 402 and the two round rods 401 to slide upward along the slide groove 5, thereby driving the two clamps 405 and the impact hammer 2 to slide upward. Since the outer walls of the two round rods 401 are both provided with limiting rings 414, the left and right sides of the strip plate 402 will be limited by the limiting rings 414 during the sliding process, and will not slide left and right, and the impact hammer 2 will not be offset. After the impact hammer 2 is lifted to the release position, the pull rod 407 is released, and the two springs 412 are released and push the two push plates 413 away from each other, thereby pushing the two slide bars 404 and the two clamping plates 405 away from each other, thereby releasing the impact hammer 2.

[0035] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
