Description

Technical Field

[0001] The utility model relates to the field of hinges, in particular to a novel reinforced hinge. Background Art

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between them. A hinge can be composed of movable components or foldable materials. Hinges are mainly installed on doors and windows, while hinges are more often installed on cabinets. They are mainly divided into stainless steel hinges and iron hinges according to the material classification. In order to allow people to enjoy better, hydraulic hinges have appeared. Their characteristic is that they provide a buffering function when the cabinet door is closed, which minimizes the noise caused by the collision of the cabinet door with the cabinet body when it is closed.

[0003] However, the existing hinges are not strong enough and are prone to deformation and damage after long-term use. Therefore, we propose a new type of reinforced hinge to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a novel reinforced hinge to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A new reinforced hinge includes a rear hinge mounting seat, a rear hinge mounting plate and a pin shaft, wherein a first through hole is provided on the upper surface of the rear hinge mounting seat, a second through hole is provided on the upper surface of the rear hinge mounting plate, the rear hinge mounting seat is hinged to the rear hinge mounting plate through the pin shaft, two hidden grooves are provided on the back side of the rear hinge mounting seat, a threaded hole is provided on the inner wall of each hidden groove, a positioning bolt is threadedly connected to the inner wall of each threaded hole, and two limiting openings are provided on the outer surface of the pin shaft, and one end of each positioning bolt extends to the inside of the limiting opening.

[0007] In a further embodiment, the outer surface of the pin shaft contacts the inner wall of the first through hole and the inner wall of the second through hole respectively.

[0008] In a further embodiment, four first receiving grooves are formed on the front side of the rear hinge mounting seat, and a first mounting hole is formed on the inner wall of each of the first receiving grooves.

[0009] In a further embodiment, the radius of the first mounting hole is 14.5 mm.

[0010] In a further embodiment, five second receiving grooves are formed on the front side of the rear hinge mounting plate, and a second mounting hole is formed on the inner wall of each of the second receiving grooves.

[0011] In a further embodiment, the radius of the second mounting hole is 12.5 mm.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The device is provided with two threaded holes on the back of the rear hinge mounting seat and two limiting openings on the outer surface of the pin shaft, so that after two positioning bolts are respectively threadedly connected to the two threaded holes, one end of the two positioning bolts can respectively extend to the inside of the two limiting openings. When the rear hinge mounting plate drives the pin shaft to rotate until the inner wall of the limiting opening contacts with one end of the positioning bolt, the rear hinge mounting plate can stop rotating, thereby effectively preventing the rear hinge mounting plate from continuously rotating and rubbing against the rear hinge mounting seat, thereby increasing the service life of the device. In addition, the device is descaled to effectively enhance the strength of the device. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 In the utility model, the new reinforced hinge includes a rear hinge mounting seat 2, a rear hinge mounting plate 6 and a pin shaft 4. A first through hole 10 is provided on the upper surface of the rear hinge mounting seat 2, and a second through hole 11 is provided on the upper surface of the rear hinge mounting plate 6. The rear hinge mounting seat 2 is hinged to the rear hinge mounting plate 6 through the pin shaft 4. Two hidden grooves 9 are provided on the back of the rear hinge mounting seat 2. A threaded hole 5 is provided on the inner wall of each hidden groove 9. A positioning bolt 13 is threadedly connected to the inner wall of each threaded hole 5. Two limiting openings 12 are provided on the outer surface of the pin shaft 4. One end of each positioning bolt 13 extends to the inside of the limiting opening 12.

[0024] The outer surfaces of the pin shaft 4 are in contact with the inner walls of the first through hole 10 and the inner walls of the second through hole 11 respectively. The rear hinge mounting seat 2 and the rear hinge mounting plate 6 can be assembled together through the pin shaft 4, and the rear hinge mounting plate 6 can rotate freely around the pin shaft 4 within a certain range. Four first receiving grooves 3 are provided on the front of the rear hinge mounting seat 2. The inner wall of each first receiving groove 3 is provided with a first mounting hole 1. The staff can use screws to penetrate the first mounting hole 1 to achieve fixed installation of the rear hinge mounting seat 2. The first receiving groove 3 can hide the fixing screws. The radius of the first mounting hole 1 is 14.5 mm. The user can choose a suitable screw to fix the rear hinge mounting seat 2 according to the radius of the first mounting hole 1.

[0025] Five second receiving grooves 7 are provided on the front of the rear hinge mounting plate 6, and a second mounting hole 8 is provided on the inner wall of each second receiving groove 7. The staff can use screws to penetrate the second mounting holes 8 to assemble the rear hinge mounting plate 6 with the box door or cabinet door, etc. The second receiving grooves 7 can hide the fixing screws. The radius of the second mounting hole 8 is 12.5 mm. The user can choose suitable screws to fix the rear hinge mounting plate 6 according to the radius of the second mounting hole 8. The rear hinge mounting seat 2, the rear hinge mounting plate 6 and the pin shaft 4 have all been deoxidized, which can effectively enhance their strength.

[0026] The working principle of the utility model is:

[0027] First, the staff uses a set of screws to penetrate the first mounting holes 1 to fix the rear hinge mounting base 2 to the inner wall of the box or cabinet, and then uses another set of screws to penetrate the second mounting holes 8 to assemble the rear hinge mounting plate 6 and the cabinet door or box door together. When the staff opens the cabinet door or box door, the rear hinge mounting plate 6 rotates, and the rotation of the rear hinge mounting plate 6 drives the pin shaft 4 to rotate. The rotation of the pin shaft 4 can drive the two limit openings 12 opened on its outer surface to change position. When the inner side walls of the two limit openings 12 are respectively in contact with the two positioning bolts 13, the rear hinge mounting plate 6 can stop rotating.
