As shown in fig. 4-5, the first support 106 includes a first plate 110 and a second plate 111. The first plate 110 is fixedly connected to the fixing frame 100. The second plate 111 is integrally connected to the first plate 110 by at least two first bolts 112. The second plate 111 is provided with a first straight groove 111A. The first bolt 112 passes through the first straight slot 111A to be in threaded connection with the first plate 110, and when the first bolt 112 is loosened, the second plate 111 can slide relative to the first bolt 112 to adjust the position. The first bolt 112 is used to fix the first plate member 110 and the second plate member 111 together. Then, the first straight groove 111A on the second plate 111 is used to make the first plate 110 and the second plate 111 have various positional relationships when the first plate 110 and the second plate 111 are fixedly installed together. The second support member includes a third plate 113 and a fourth plate 114. The third plate 113 is fixedly connected to the holder 100.

The second bolt 115 is used to fix the third plate 113 and the fourth plate 114 together. Then, the second straight groove 114A of the fourth plate 114 is used to make the third plate 113 and the fourth plate 114 have various positional relationships when the third plate 113 and the fourth plate 114 are fixedly installed together. That is, the positional relationship between the first link 108 and the second link 109 is adjusted so that the first link 108 is in a distant state and a close state.

As shown in fig. 7, first arcuate slot 108C is configured as a structure formed by at least a portion of an arc centered about first connection aperture 108A; the second arc-shaped groove 109C is configured as a structure formed by at least a partial arc centered on the third coupling hole 109A.

As shown in fig. 6-7, the first link 108 is connected to the second plate member 111 through the first connection hole 108A and the first arc-shaped slot 108C. That is, the first connecting member 108 and the second plate member 111 are fixed together by two third bolts 126, one inserted into the first connecting hole 108A and one inserted into the first arc-shaped groove 108C. The second plate member 111 has two threaded holes corresponding to the reference numerals 108A and 108C, respectively, and the third bolt 126 is simultaneously inserted into the threaded hole of the second plate member 111. During installation, the first connection hole 108A is first aligned with a threaded hole in the second plate 111, and then the first curved slot 108C is aligned with another threaded hole in the second plate 111. Since the first arc-shaped groove 108C is a partial arc formed in a circle with the center of the first connection hole 108A. The first connector 108 can rotate a partial angle about the third bolt 126 on the first connection hole 108A. The first arc-shaped slot 108C does not disengage from the other threaded hole in the second plate 111, and the two can also be connected by the third bolt 126. I.e. it is achieved that the position of the first connection member 108 has an adjustable state.

The third bolt 126 on the first connector 108 is the first locking member. The third bolt 126 on the second connector 109 is the second locking member.

As shown in fig. 6-7, second link 109 is connected to fourth plate 114 via third connecting hole 109A and second arcuate slot 109C. That is, the second connecting member 109 and the fourth plate member 114 are fixed together by two fourth bolts 127, one inserted into the third connecting hole 109A and one inserted into the second arc-shaped groove 109C. The fourth plate member 114 has a threaded hole therein, and a fourth bolt 127 is also inserted into the threaded hole in the fourth plate member 114. During installation, the third connecting hole 109A is aligned with a threaded hole of the fourth plate 114, and then the second arc-shaped slot 109C is aligned with another threaded hole of the fourth plate 114. Since the second arc-shaped groove 109C is a partial arc formed by rounding the center of the third coupling hole 109A. The second link 109 can be rotated by a partial angle about the fourth bolt 127 on the third connection hole 109A. The second arc-shaped slot 109C does not disengage from the other threaded hole in the fourth plate 114, and the two can also be connected by the fourth bolt 127. I.e. it is achieved that the position of the second connection 109 has an adjustable state.

As shown in fig. 1, since the door frame 101 and the fixing frame 100 are connected by the hinge part 103, and the combination of the hinge part 103 and the door frame 101 allows the hinge part 103 to be a member to be detected. Hinge member 103 includes: a first mounting member 116 fixedly coupled to the fixing bracket 100 such that the first mounting member 116 (see fig. 4) and the fixing bracket 100 form an integral body, a second mounting member 117 fixedly coupled to the door frame 101 such that the second mounting member 117 (see fig. 4) and the fixing bracket 100 form an integral body, and a folding plate 118 coupled to the first mounting member 116 and the second mounting member 117, respectively. Since the fixing frame 100 and the door frame 101 and the connecting means 104 are provided for detecting the folding plate 118 (see fig. 4), the cost of the fixing frame 100 and the door frame 101 and the connecting means 104 is much higher than that of the folding plate 118. The connecting means 104 is for providing a rotatable connection between the door frame 101 and the holder 100. However, since the folding plates 118 have a plurality of types, the connecting device 104 is detached for each type of folding plate 118 if the connecting device 104 is provided with a plurality of types. This results in increased difficulty and reduced speed of replacement, since it is mentioned above that the distance between the first connecting member 108 (see fig. 3) and the second connecting member 109 (see fig. 3) can be adjusted, i.e. can be adapted to a plurality of different types of folding plates 118.

As shown in fig. 2, the arm opener 105 includes: a driving member 119 fixedly connected to the mounting plate 102, a rotating arm 120 fixedly connected to an output end of the driving member 119, and a link member 121 hinged to the rotating arm 120 and the door frame 101. The drive 119 in this embodiment is an electric motor. The motor is fixedly attached to the mounting plate 102. The output end of the motor is connected with a reducer 128, and the output end of the reducer 128 is connected with a change gear box 129. The rotation in the horizontal direction is changed to the rotation in the vertical direction, and then the rotating arm 120 is rotated. The rotating arm 120 and the link member 121 are rotatably coupled. The link member 121 is rotatably coupled to the door frame 101. The rotating arm 120 and the link member 121 constitute a structure similar to a crank slider to open and close the door frame 101. The rotating arm 120 is under the link member 121 to avoid interference. The rotation of the rotating arm 120 by different angles will cause the link member 121 to drive the door frame 101 to open by different angles, and thus the folding plate 118 will have multiple detection methods during detection.

As shown in fig. 1, a guide wheel 122 for reducing the opening and closing friction of the door frame 101 is installed below the door frame 101. The two door frames 101 are arranged symmetrically with respect to the center of gravity of the mounting plate 102; two arm openers 105 are provided and are respectively connected to the two door frames 101. Two groups of detection are simultaneously arranged, the detection speed is increased, and a connecting rod 123 for hanging a heavy object is fixedly arranged above the fixing frame 100. The weight is hung on the connecting rod 123 through a rope, so that the door frame 101 can be subjected to resistance when the door is opened, and the mechanical property of the folding plate 118 can be detected.

The foregoing description is only exemplary of the preferred embodiments of the disclosure and is illustrative of the principles of the technology employed. It will be appreciated by those skilled in the art that the scope of the invention in the embodiments of the present disclosure is not limited to the specific combination of the above-mentioned features, but also encompasses other embodiments in which any combination of the above-mentioned features or their equivalents is made without departing from the inventive concept as defined above.
