[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Combination Figures 1 to 9The hinge fixing fixture shown includes a fixture body 1, on which a hinge placement seat 2 is mounted. One end of the hinge placement seat 2 is provided with a retractable hinge middle arm positioning unit 3, and the other end is provided with a hinge lower arm adsorption unit 4. Hinges middle arm baffles 5 are respectively installed on both sides of the hinge placement seat 2 between the hinge middle arm positioning unit 3 and the hinge lower arm adsorption unit 4. At least one hinge middle arm baffle 5 has a second spring 25 located below it, causing the second spring 25 to push the hinge middle arm baffle 5 upwards, thereby cooperating with other mounting mechanisms to move up and down. A hinge middle arm baffle 5 is provided on the side of the hinge middle arm baffle 5 closest to the hinge lower arm adsorption unit 4. The hinge middle arm limiting plate 6 is located on the chain placement seat 2. In this embodiment, the hinge middle arm 26 is placed between the hinge middle arm baffles 5 on both sides. The hinge middle arm positioning unit 3 extends and retracts to push the hinge middle arm 26 against the hinge middle arm limiting plate 6, thereby completing the position positioning of the hinge middle arm 26. Only one end of the hinge small arm 28 needs to be inserted into the hinge cam 27, and then the hinge small arm adsorption unit 4 adsorbs and fixes the hinge small arm 28 in position, thereby positioning the hinge middle arm 26, hinge cam 27 and hinge small arm 28, so as to facilitate hinged installation by pin. There is no need for manual alignment and assembly of the hinge structure, which greatly improves work efficiency.

[0025] The hinge middle arm positioning unit 3 of this embodiment includes a fixed seat 7 installed on the hinge placement seat 2. The fixed seat 7 has a push rod cavity 8, and a middle arm push rod 10 is installed through the push rod cavity 8. A positioning groove 12 is provided at one end of the middle arm push rod 10 near the hinge small arm adsorption unit 4. After the hinge middle arm 26 is placed between the hinge middle arm baffles 5 on both sides, the positioning groove 12 is pushed against the hinge cam 27 by pressing the middle arm push rod 10, so that the hinge cam 27 is accommodated in the positioning groove 12, and the hinge middle arm 26 is pushed against the hinge middle arm limiting plate 6, thereby completing the position positioning of the hinge middle arm 26, which is relatively efficient.

[0026] In this embodiment, the fixed base 7 has guide grooves 9 on both sides that communicate with the top rod cavity 8, and the top rod 10 has limit rod holes 11 on both sides that communicate with each other. A limit rod 13 is inserted through the limit rod hole 11 and is inserted through the guide groove 9. Under the action of the limit rod 13 and the guide groove 9, the top rod 10 moves more stably and is positioned more accurately.

[0027] It is worth noting that, in this embodiment, a first longitudinal spring groove is provided at the lower end of the push rod cavity 8, and a first spring 14 is installed in the first longitudinal spring groove. The lower end of the first spring 14 abuts against the lower end of the first longitudinal spring groove, and the upper end of the first spring 14 abuts against the lower end face of the push rod 10. Under the action of the first spring 14, the push rod 10 is in a pressing state, preventing the push rod 10 from easily moving and causing the hinge arm 26 to shift.

[0028] The hinge arm adsorption unit 4 in this embodiment includes an arm positioning seat 15 mounted on the hinge placement seat 2. The arm positioning seat 15 has a magnet top rod cavity 16, and a movable magnet top rod 19 is provided in the magnet top rod cavity 16. A magnet mounting hole 22 is provided at one end of the magnet top rod 19 near the hinge arm positioning unit 3, and a magnet is installed in the magnet mounting hole 22. By moving the magnet top rod 19, the magnet moves closer to or away from the hinge arm 28, thereby adsorbing and fixing or releasing the hinge arm 28, thus making it easier to position the hinge arm 28 for the assembly of the hinge.

[0029] Specifically, a first slider hole 17 communicating with the magnet push rod cavity 16 is provided on both sides of the forearm positioning seat 15. A second slider hole 20 is provided in the magnet push rod 19. A slider 23 is installed in the second slider hole 20. A guide inclined hole 24 is provided on the slider 23. A connecting shaft 21 is installed in the guide inclined hole 24. The connecting shaft 21 is installed longitudinally in the slider connecting hole 20. Both ends of the slider 23 extend to the outside of the first slider hole 17. During the movement of the slider 23, the connecting shaft 21 moves in the guide inclined hole 24, thereby driving the magnet push rod 19 to reciprocate, so that the magnet can move closer to or away from the hinge forearm 28.

[0030] It is worth noting that the hinge placement seat 2 has a slot 18, which is connected to the first slider hole 17. The connecting shaft 21 passes through the guide oblique hole 24, the magnetic push rod 19 and the slot 18 on the slider 23. The bottom of the connecting shaft 21 abuts against the upper surface of the fixture body 1. By limiting the movement of the magnetic push rod 19 by the connecting shaft 21, the magnetic push rod 19 can be made more stable in the magnetic push rod cavity 16, preventing loosening and displacement.

[0031] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
