For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0034] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0035] This embodiment provides a compression assembly tool 30 for a hinge 10, which is used to Figure 1 The hinge 10 shown is assembled. Figure 1 As shown, the hinge 10 includes a connecting middle frame 11, a plurality of first swing arms 12, a plurality of second swing arms 13, a first support plate 14 and a second support plate 15. The first swing arm 12 and the second swing arm 13 are both rotatably connected to the connecting middle frame 11. The first swing arm 12 and the second swing arm 13 are respectively arranged on both sides of the connecting middle frame 11. The first support plate 14 is plugged into the plurality of first swing arms 12, and the second support plate 15 is plugged into the plurality of second swing arms 13.
[0036] The first support plate 14 (or the second support plate 15) may include only the first support plate 14 body, or may include a support plate body and at least one auxiliary plate. In this case, if there is a connection relationship between the support plate body and the auxiliary plate, the two can be connected and then set on the following assembly tool 20. In this case, the support plate body is connected to a part of the plurality of swing arms, and the auxiliary plate is connected to another part.
[0037] It should be noted that the above-mentioned "plug-in" does not limit the connection relationship between the first support plate 14 and the first swing arm 12 to a sliding connection. When the connection relationship between a first swing arm 12 and the first support plate 14 is a rotational connection, it is only necessary to reserve a first rotation hole on the first swing arm 12, reserve a corresponding second rotation hole on the first support plate 14, and set a plug-in slot that can reach the second rotation hole on the first support plate 14, so that when the first swing arm 12 is plugged into the first support plate 14 through the plug-in slot, the first rotation hole and the second rotation hole are aligned, and then only an axis needs to be passed through the first rotation hole and the second rotation hole. The connection relationship between the second support plate 15 and the second swing arm 13 is also not limited to a sliding connection, which will not be repeated.
[0038] The number of the first rotary arms 12 and the number of the second rotary arms 13 may be the same or different, and the rotation of the first rotary arms 12 and the second rotary arms 13 may be synchronous or asynchronous.

When the second pressing seat 32 is fixedly connected to the first pressing seat 31, the second pressing block 321 and the corresponding first pressing block 311 are aligned and pressed against the two sides of a swing arm so that they are at a preset inclination angle.
[0042] The fixed connection between the first pressure fixing seat 31 and the second pressure fixing seat 32 is a detachable fixed connection, such as a snap-fit fixed connection or a locking fixed connection.
[0043] Please refer to Figure 2 and Figure 3 In order to improve the convenience of fixed connection and disassembly between the first pressure fixing seat 31 and the second pressure fixing seat 32, eccentric locking members 33 can be provided at both ends of the first pressure fixing seat 31, and the eccentric locking members 33 include an anchor rod 331 and an eccentric locking pressure rod 332. One end of the anchor rod 331 is provided on the first pressure fixing seat 31, and the other end is rotatably connected to the eccentric locking pressure rod 332; an anchor groove 322 corresponding to the anchor rod 331 is provided on the second pressure fixing seat 32, the anchor rod 331 is penetrated into the anchor groove 322, and when the eccentric locking pressure rod 332 rotates to press against the end face of the second pressure fixing seat 32 away from the first pressure fixing seat 31, the second pressure fixing seat 32 is locked and fixed on the first pressure fixing seat 31.
[0044] Please refer to Figure 3 and Figure 4 The eccentric locking pressure rod 332 includes an eccentric wheel 332a and a pressure rod 332b. The eccentric wheel 332a is rotatably connected to the anchor rod 331, and the pressure rod 332b is fixedly connected to the eccentric wheel 332a. In order to improve the stability of the fixed connection between the first pressure fixing seat 31 and the second pressure fixing seat 32, a locking groove 323 corresponding to the cam end of the eccentric wheel 332a can be provided on the second pressure fixing seat 32. When the eccentric wheel 332a rotates until the cam end is embedded in the locking groove 323, the second pressure fixing seat 32 is locked and fixed on the first pressure fixing seat 31.
[0045] In order to further improve the stability of the first pressing seat 31 and the second pressing seat 32 when they are fixedly connected, and to improve the self-locking property of the eccentric locking rod 332, as shown in FIG. Figure 4 As shown, a cutting surface 332c can also be set on the eccentric wheel 332a to form a convex point 332d at the cam end of the eccentric wheel 332a, and a protruding surface 323a is set in the locking groove 323 to form a concave point 323b at the bottom of the locking groove 323. When the eccentric wheel 332a rotates until the convex point 332d is embedded in the concave point 323b, the second pressure fixing seat 32 is locked and fixed on the first pressure fixing seat 31.
[0046] In order to improve the alignment accuracy when the first press-fixing seat 31 and the second press-fixing seat 32 are connected, as shown in FIG. Figure 2 As shown, at least one first alignment rod 312 may be provided on the first pressure fixing seat 31 , and a first alignment hole 324 corresponding to the alignment rod may be provided on the second pressure fixing seat 32 .
[0047] The compression assembly device 30 in this embodiment, when assembling the first support plate 14, only needs to align the insertion hole in the first support plate 14 with the corresponding first swing arm 12, so that the first support plate 14 and all the first swing arms 12 can be connected at one time. When assembling the second support plate 15, only needs to align the insertion hole in the second support plate 15 with the corresponding second swing arm 13, so that the second support plate 15 and all the second swing arms 13 can be connected at one time, which greatly reduces the difficulty of assembling the hinge and improves the assembly efficiency.
[0048] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
