[0002] Doors are products required by every household. Doors are used to separate the inside and outside of a house, thereby protecting the privacy of the householders. Doors need to be opened and closed during daily use. Therefore, the number of times a door can withstand opening and closing is a very important index in door functions.
[0003] Currently, there is no device specifically for detecting the number of times a door can withstand opening and closing. Therefore, there is currently no good method for detecting the number of times a door can withstand opening and closing. Summary of the Invention
[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and propose a door function testing device that can effectively detect the number of times a door can withstand opening and closing, thereby facilitating the subsequent research and development and upgrading of door products.

Detailed Embodiments
[0016] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.
[0017] It should be noted that in the following solutions, the orientation concepts of "left", "right", "up", "down", "front", "back", "inside", and "outside" are all relative directions, and will not be listed one by one here.
[0018] A door function testing device, refer to Figures 1-4 , including a frame body 1 and a support rod 2 located on the front side of the frame body 1. A door product 3 is rotatably arranged on the rear side of the frame body 1. An elastic band 21 is arranged on the support rod 2, and the elastic band 21 is connected to the door product 3. A pushing component 4 is arranged on the side wall of the frame body 1 for pushing the door product 3 to rotate away from the support rod 2. Triangular support parts 11 are arranged at both ends on the front side of the frame body 1 for supporting the frame body 1.
[0019] The pushing component 4 includes a pushing cylinder 41 connected to the frame body 1 and a support hinge seat 42 arranged on the side wall of the frame body 1. The end of the support hinge seat 42 is hinged to the midpoint of the hinge rod 43. The output end of the pushing cylinder 41 is connected to one end of the hinge rod 43. A push plate 44 is arranged at the other end of the hinge rod 43. When the pushing cylinder 41 extends, the push plate 44 pushes the door product 3 to rotate away from the support rod 2.
[0020] A step 12 matching the size and shape of the door product 3 is provided on the frame body 1. The inside of the frame body 1 is hollow. A plurality of contact parts 13 are evenly slidably penetrated through the step 12. An induction part 14 is arranged inside the frame body 1 and is in one-to-one correspondence with the position and quantity of the contact parts 13. Reset parts 15 are arranged on both sides of the part of the contact part 13 located inside the frame body 1, and a reset spring 16 with both ends connected to both of them is arranged between the reset part 15 and the inner wall of the frame body 1. In the normal state of the reset spring 16, the contact part 13 and the induction part 14 are separated.
[0021] A positioning plate 6 is arranged on the upper side of the frame body 1. A telescopic cylinder 61 is arranged on the rear side of the positioning plate 6. The lower output end of the telescopic cylinder 61 is provided with a reset plate 62. A rubber block 63 is arranged on the lower side of the reset plate 62. A reset block 64 is arranged on the lower side of the rubber block 63. A first inclined surface 65 with both ends respectively connected to its top and bottom is arranged on the front side of the reset block 64. A flat surface 66 is connected to the top of the rear side of the reset block 64, and a second inclined surface 67 connected to the bottom of the reset block 64 is connected to the lower end of the flat surface 66.
[0022] Four uniformly annularly distributed infrared sensors 5 are arranged on the peripheral side of the frame body 1. The infrared sensors 5 are signal-connected to the telescopic cylinder 61 and the pushing cylinder 41.
[0023] In the initial state, the stroke of the telescopic cylinder 61 is the shortest. At this time, the plane 66 is in close contact and flush with the frame 1. The pushing cylinder 41 is driven to work reciprocally in the forward and backward directions of elongation and shortening, thereby driving the door product 3 to rotate away from the support rod 2. The elastic band 21 deforms, and the deformation force pulls the door product 3 back. The door product 3 overcomes the restoring force of the rubber block 63 and enters the step 12. The door product 3 pushes the contact member 13 to slide and contact the sensing member 14, and each contact is counted once. The restoring force of the return spring 16 cannot overcome the restoring force of the rubber block 63 (the pushing cylinder 41 needs to apply a thrust to the door product 3). If all the contact members 13 are in contact with the sensing member 14, it is determined that the door product is not damaged at this time, and the pushing cylinder 41 can continue to work; if at least one contact member 13 is not in contact with the sensing member 14, it is determined that the door product is damaged at this time, and the number of opening and closing times counted at this time is the number of opening and closing times that the door product can withstand.
[0024] If someone enters the periphery of the frame 1 and is sensed by the infrared sensor 5 at this time, the infrared sensor 5 sends signals to the telescopic cylinder 61 and the pushing cylinder 41 at this time. The pushing cylinder 41 stops working. The telescopic cylinder 61 elongates downward so that the plane 66 corresponds to the step 12. At this time, the door product 3 enters the step 12 under the action of the restoring force of the elastic band 21, and the plane 66 jams the door product 3 to prevent the extreme situation of the door product opening outward when the elastic force of the elastic band 21 is too large.
[0025] The above is only the preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above description or the technology or knowledge in the relevant field. And the changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims of the present invention.
