Description

Technical Field

[0001] This application relates to the field of building technology, and more specifically, to a simple tooling for positioning welded hinges. Background Technology

[0002] In fields such as architecture, acoustics, and mechanical structures, it is generally necessary to isolate the working or equipment operating environment from the surrounding external environment in order to obtain a certain working or equipment operating environment. In order to create a good working or equipment operating environment, it is necessary to manufacture facilities such as soundproof doors, noise-absorbing doors, steel doors, and safety doors.

[0003] To allow for smooth rotation and opening of these doors, rotating hinges are typically required. When selecting rotating hinges, it is important to choose simple, suitable, and easy-to-manufacture and install hinges while meeting the allowable load requirements. Welded hinges are usually the best choice to meet these requirements.

[0004] To address the aforementioned issues, this application provides a simple tooling for positioning welding hinges. Utility Model Content

[0005] The simple tooling for positioning welded hinges provided in this application adopts the following technical solution:

[0006] A simple tooling for positioning welding hinges includes a limiting frame, an auxiliary mechanism on the outside of the limiting frame, and the auxiliary mechanism extending into the interior of the auxiliary mechanism.

[0007] The auxiliary mechanism includes a door leaf located inside a limiting frame. A snap-fit ​​groove is provided on the front side of the limiting frame, and a snap-fit ​​block is embedded inside the snap-fit ​​groove. A limiting groove is provided on one side of the snap-fit ​​block, and a clamping plate is embedded inside the limiting groove. An anti-slip pad is fixedly connected to the rear side of the clamping plate, and the anti-slip pad is in contact with the rear side of the door leaf. A threaded plate is fixedly connected to one side of the clamping plate, and the threaded plate is embedded inside the snap-fit ​​block. Two screws are threaded into the threaded plate, and the front and rear ends of the two screws extend to the front and rear sides of the snap-fit ​​block respectively. Worm gears are fixedly sleeved on the outer sides of both screws, and worms are meshed on one side of each of the two worm gears. The top and bottom ends of the worms extend to the top and bottom inner sides of the snap-fit ​​block respectively, and a connecting component is provided on the outer side of the worm.

[0008] Furthermore, both screws are movably connected to the locking block via bearings, and the worm gear is movably connected to the locking block via bearings.

[0009] The above technical solutions enable the screw and worm to rotate more smoothly and firmly.

[0010] Furthermore, the connecting component includes a square telescopic rod, which is fixedly connected to the top of the worm gear.

[0011] The above technical solution, by setting a square telescopic rod, serves both to limit the movement of the worm gear and to ensure that the worm gear can be rotated later, thus improving the flexibility of the device.

[0012] Furthermore, a knob is fixedly sleeved on the outer side of the top of the square telescopic rod, and the knob is made of non-slip material.

[0013] The above technical solution enhances the friction between the palm and the knob by making the knob with a non-slip material, thereby improving operating efficiency.

[0014] Furthermore, a positioning groove is provided on the outer side of the square telescopic rod, and a positioning block is fixedly connected to the top of the limiting frame.

[0015] The above technical solution, through the cooperation of the positioning groove and the positioning block, facilitates the positioning of the knob in the later stage.

[0016] Furthermore, the top of the limiting frame is provided with a fixed joint, a door frame is provided on one side of the fixed joint, and a planar bearing and a rotating joint are provided on the outer side of the top of the fixed joint, with the planar bearing located at the bottom of the rotating joint.

[0017] In summary, this application has the following beneficial technical effects:

[0018] In use, first pull the knob upwards, at which point the telescopic end of the square telescopic rod is in the extended state. Then rotate the knob to rotate the worm gear. Since the worm gear meshes with two worm wheels, it can rotate the two screws. Because the clamping plate matches the limiting groove, the clamping plate can drive the anti-slip pad to move closer to the door leaf and fit. When the anti-slip pad is tightly fitted to the door leaf, the knob can be pressed downwards. Through the cooperation of the positioning groove and the positioning block, the knob is positioned, allowing the limiting bracket to be installed on the outside of the door leaf. The above structure is not only simple in structure, but also easy to install and maintain. Attached Figure Description

[0031] Example:

[0032] This application discloses a simple tooling for positioning welded hinges. Please refer to [link / reference]. Figure 1 , Figure 2, Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 It includes a limiting frame 1, an auxiliary mechanism on the outside of the limiting frame 1, and the auxiliary mechanism extends into the interior of the auxiliary mechanism;

[0033] The auxiliary mechanism includes a door leaf 2, which is located inside the limiting frame 1. The limiting frame 1 has a snap-fit ​​groove on its front side, and a snap-fit ​​block 3 is embedded inside the snap-fit ​​groove. A limiting groove is opened on one side of the snap-fit ​​block 3, and a clamping plate 4 is embedded inside the limiting groove. An anti-slip pad 5 is fixedly connected to the rear side of the clamping plate 4. The anti-slip pad 5 is in contact with the rear side of the door leaf 2. A threaded plate 6 is fixedly connected to one side of the clamping plate 4. The threaded plate 6 is embedded inside the snap-fit ​​block 3. Two screws 7 are threadedly inserted inside the threaded plate 6. The front and rear ends of the two screws 7 extend to the front and rear sides of the snap-fit ​​block 3, respectively. Worm gears 8 are fixedly sleeved on the outer side of the two screws 7. A worm 9 is meshed on one side of the two worm gears 8. The top and bottom ends of the worm 9 extend to the top and bottom sides of the snap-fit ​​block 3, respectively. The two screws 7 and the snap-fit ​​block 3 are movably connected by bearings. The worm 9 and the snap-fit ​​block 3 are movably connected by bearings.

[0034] Please see Figure 6 and Figure 7 The worm 9 is provided with a connecting component on its outer side. The connecting component includes a square telescopic rod 10, which is fixedly connected to the top of the worm 9. By setting the square telescopic rod 10, the worm 9 can be limited without affecting the subsequent rotation of the worm 9, thus improving the flexibility of the device.

[0035] Please see Figure 5 and Figure 6 A knob 11 is fixedly sleeved on the outer side of the top of the square telescopic rod 10. The knob 11 is made of non-slip material. A positioning groove is opened on the outer side of the square telescopic rod 10. A positioning block 12 is fixedly connected to the top of the limit frame 1. Because the knob 11 is made of non-slip material, the friction between the palm and the knob 11 can be enhanced, thereby improving the operating efficiency. At the same time, the positioning groove and the positioning block 12 cooperate with each other to facilitate the positioning of the knob 11 in the later stage.

[0036] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The top of the limiting frame 1 is provided with a fixed pair 13, and a door frame 14 is provided on one side of the fixed pair 13. A plane bearing 15 and a rotating pair 16 are provided on the outer side of the top of the fixed pair 13, and the plane bearing 15 is located at the bottom of the rotating pair 16.

[0037] The implementation principle of this embodiment is as follows: When in use, the knob 11 can be pulled upward first. At this time, the telescopic end of the square telescopic rod 10 is in the stretched state. Then, the knob 11 is rotated, so that the worm 9 rotates. Since the worm 9 is meshed with the two worm wheels 8, the two screws 7 can rotate. Since the clamping plate 4 matches the limiting groove, the clamping plate 4 can drive the anti-slip pad 5 to move closer to the door leaf 2. When the anti-slip pad 5 is tightly attached to the door leaf 2, the knob 11 can be pressed downward. The positioning groove and the positioning block 12 cooperate with each other to position the knob 11, so that the limiting frame 1 can be installed on the outside of the door leaf 2. The above structure is not only simple in structure, but also easy to install and maintain.

[0038] After the limit frame 1 is installed and fixed, the plane bearing 15 and the rotating joint 16 are fitted into the limit frame 1. After the rotating joint 16 is firmly welded to the contact surface of the door leaf 2, the limit frame 1 is removed. Then, the plane bearing 15 and the fixed joint 13 are fitted into the rotating joint 16 to complete the welding operation of the contact surface between the fixed joint 13 and the door frame 14. Through the above structure, a complete rotating joint 16 structure system can be formed.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
