[0024] Reference Figure 3-6 As shown, a general-purpose arm hinge includes an arm hinge head 11 and an arm hinge rod 12. The arm hinge head 11 is composed of an arm hinge connecting block 111 and a hinge plate located on the arm hinge connecting block 111. At least one hinge plate 112 is provided and can be placed in the arm hinge filling interval a after being symmetrical about the horizontal center plane of the arm hinge connecting block 111. The arm hinge rod 12 is provided with at least one first channel 121 and a second channel 122 leading to the hinge plate 112 and the arm hinge filling interval a.

[0025] Specifically, to ensure the connection strength between the two arm hinges 1 forming the arm hinge seat, two hinge plates 112 are provided, including a main hinge plate 1121 and a secondary hinge plate 1122. The arm hinge filling interval a is the interval area between the main hinge plate 1121 and the secondary hinge plate 1122. The main hinge plate 1121 and the secondary hinge plate 1122 are both circular and have the same diameter. A through hole b is provided at the center of both the main hinge plate 1121 and the secondary hinge plate 1122, and the two sets of through holes b are concentric.

[0026] To ensure that the pull rope installed in the main hinge plate 1121 can be embedded in the main hinge plate 1121, firstly to prevent the pull rope from deviating, and secondly to ensure that the pull rope does not protrude from the main hinge plate 1121 and is not restricted in installation, specifically, the main hinge plate 1121 is provided with an arc-shaped groove 11211 communicating with the first channel 121. The arc-shaped groove 11211 is composed of a first segment g, a second segment d, and a third segment e. The second segment d is an arc-shaped segment concentric with the main hinge plate 1121. The first segment g and the second segment d are both tangent to the second segment d. The first channel 121 is directly connected to the first segment g, and the pull rope can pass through the first channel 121 and follow the path of the first segment g, the second segment d, and the third segment e.

[0027] To facilitate the installation of the pull rope, an anti-detachment clip is provided at the end of the pull rope. The anti-detachment clip is placed in the first channel 121, which is an open channel located on the opposite side of the main hinge plate 1121 and the secondary hinge plate 1122 on the arm hinge rod 12. An opening f is provided at the corresponding position of the first channel 121. The pull rope is placed at the first segment g, the second segment d, and the third segment e, so that the end of the pull rope passes through the first channel 121, and the anti-detachment clip is installed at the end of the pull rope.

[0028] It should be noted that the second channel 122 is closed and consists of a central portion 1221 and an eccentric portion 1222. The pull rope is placed entirely within the second channel 122. Since the arm hinge 1 needs to rotate, under normal circumstances, the pull rope is placed at the central portion 1221. When the arm hinge 1 rotates, the pull rope can be deflected to the eccentric portion 1222 to avoid friction between the pull rope and the inner wall of the second channel 122.

[0029] like Figure 2 The image shows the arm hinge seat, which is formed by splicing two arm hinges 1, including a first arm hinge 1-1 and a second arm hinge 1-2; the hinge plate 112 of the first arm hinge 1-1 is placed in the arm hinge filling section a of the second arm hinge 1-2; the hinge plate 112 of the second arm hinge 1-2 is placed in the arm hinge filling section a of the first arm hinge 1-1; the through holes b on the first arm hinge 1-1 and the second arm hinge 1-2 are concentric; a connecting rod 2 is provided to pass through the two through holes b.

[0030] When the two arm hinges 1 are connected, the second channel 122 of the first arm hinge 1-1 aligns with the arc groove 11211 of the main hinge plate 1121 on the second arm hinge 1-2 and connects to the first channel 121; the second channel 122 of the second arm hinge 1-2 aligns with the arc groove 11211 of the main hinge plate 1121 on the first arm hinge 1-1 and connects to the first channel 121. The pull rope passes through the second channel 122 of one of the arm hinges 1 into the arc groove 11211 on the main hinge plate 1121 of the other arm hinge 1 and extends along the arc groove 11211 into the first channel 121 thereon. When the two arm hinges 1 rotate, the pull rope moves within the range of the arc groove 11211.

[0031] It should be noted that, in order to ensure smoother rotation between the first arm hinge 1-1 and the second arm hinge 1-2, a bearing sleeve 3 is provided at the through hole b where the main hinge plate 1121 of the first arm hinge 1-1 and the second arm hinge 1-2 is located. Specifically, this is done on both the first arm hinge 1-1 and the second arm hinge 1-2. A first stepped groove 11212 is provided on the end face of the main hinge plate 1121 on the side away from the secondary hinge plate 1122. The end body of the bearing sleeve 3 is placed in the through hole b, and the end of the bearing sleeve 3 is placed in the first stepped groove 11212.

[0032] Meanwhile, the purpose of the connecting rod 2 is to ensure that the two arm hinges 1 will not detach after being connected. Therefore, it is necessary to restrict both ends of the connecting rod 2. Specifically, a second stepped groove 11221 is provided on the end face of the secondary hinge plate 1122 away from the main hinge plate 1121. The end of the connecting rod 2 is placed in one of the second stepped grooves 11221, and a washer c is provided in the other second stepped groove 11221. At the same time, a shaft hole 21 is provided on the lower end face of the connecting rod 2. A fastener 4 passes through the washer c and enters into the shaft hole 21. The fastener 4 is selected as a blind rivet. The end of the blind rivet is located in the middle part. The head end of the blind rivet is inserted into the shaft hole 21. After the blind rivet is squeezed in the shaft hole 21, the head end of the blind rivet is secured in the shaft hole 21. Then the tail end of the blind rivet is broken off.

[0033] like Figure 1 The image shows an arm assembly. An insertion step 1111 is formed between the arm hinge rod 12 and the arm hinge connecting block 111. The arm hinge rod 12 is inserted into one end of the arm rod 5 and the end face of the arm rod 5 abuts against the insertion step 1111. Subsequently, the arm rod 5 can be fixed to the arm hinge rod 12 by screwing screws into the arm rod 5 and fastening them to the arm hinge rod 12.

[0034] The working process of this utility model is as follows: First, the arm hinge seat is assembled, and the pull rope is threaded onto the first arm hinge 1-1 and the second arm hinge 1-2. Then, the main hinge plate 1121 and the auxiliary hinge plate 1122 of the first arm hinge 1-1 and the second arm hinge 1-2 are inserted in a staggered manner. The bearing sleeve 3 is inserted into the through hole b on the main hinge plate 1121 of the two arm hinges 1 respectively. The connecting rod 2 is inserted from the upper end of the first arm hinge 1-1. The washer c is placed in the second step groove 11221 of the second arm hinge 1-2. Then, the structure is fixed by the fastener 4. The two arm rods 5 are fixed on the arm hinge rods 12 of the first arm hinge 1-1 and the second arm hinge 1-2 respectively.
