Description

Technical Field

[0001] The invention relates to the field of positioning hinges, in particular to a simple damping directional hinge structure for a metering box. Background Art

[0002] The damping hinge is a device that controls the hinge to open and close smoothly and slowly. It is usually composed of two or more hinges, at least one of which is connected to a damping mechanism. Such hinges are widely used in doors, windows, cabinets, etc.

[0003] Traditional hinges cannot be positioned and fixed, and the free movement of the box door during assembly, wiring, inspection and maintenance brings construction inconvenience and safety hazards, so there is room for improvement. Summary of the invention

[0004] The object of the present invention is to provide a simple damping directional hinge structure for a metering box to solve the problems raised in the above-mentioned background technology, which has the advantages of positioning and fixing.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a simple damping directional hinge structure for a metering box, comprising a hinge sleeve, wherein the hinge sleeve comprises a bent sleeve plate, a rotating shaft is installed in the sleeve plate, and the side surface of the rotating shaft is provided with long grooves symmetrically arranged about the axis center line of the rotating shaft, two ends of the long grooves located in the middle of the rotating shaft are connected to each other to form a first through groove, and the other ends of the two long grooves are connected to each other to form a second through groove, and the second through groove is connected to the outside, the first through groove, the groove and the second through groove are jointly provided with the same spring, the middle part of the spring protrudes outward, and the side surface of the sleeve plate is provided with a plurality of slots symmetrically arranged about the axis center line of the sleeve plate.

[0006] By adopting the above technical scheme, a spring is installed in the rotating shaft, and the hinge sleeve matched with it corresponds to multiple door opening angles. During the movement of the door, the spring and the sleeve plate rub to form a damping effect. When the door is opened to the corresponding position, the spring on the hinge shaft pops out and is stuck in the corresponding slot position to realize the positioning and fixation of the door at multiple angles. Multiple angles can be preset according to needs. The first through groove, the groove and the second through groove are used to place the same spring. When the middle part of the spring protrudes outward and is in the slot, it can play a role of positioning and fixing. When the middle part of the spring protrudes outward and is squeezed against the sleeve plate, it can play a damping role.

[0007] As a further solution of the present invention: the hinge sleeve includes a mounting plate, a connecting plate is integrally connected between the mounting plate and the sleeve plate, and mounting holes are provided at both ends of the mounting plate.

[0008] By adopting the above technical solution, the mounting plate is installed using the mounting holes.

[0009] As a further solution of the present invention: an arc-shaped protrusion is provided in the middle of the rotating shaft.

[0010] By adopting the above technical solution, the protrusion can squeeze the spring in the rotating shaft, so that the middle part of the spring is always in a state of protruding outwards.

[0011] As a further solution of the present invention: the rotating shaft is integrally connected with semicircular blocks located at both ends of the second through groove.

[0012] By adopting the above technical solution, the semicircular block plays a role of limiting, thereby increasing the stability of the spring when it is in the rotating shaft.

[0013] As a further solution of the present invention: the mounting plate is provided with an inwardly recessed bending groove.

[0014] By adopting the above technical solution, the setting of the bending groove makes it easier to bend the connecting plate.

[0015] As a further solution of the present invention: a fixing block is integrally connected to one side of the shaft sleeve plate, and the connecting plate is provided with a fixing groove for accommodating the fixing block.

[0016] By adopting the above technical solution, the cooperation between the fixing block and the fixing groove increases the stability between the shaft sleeve plate and the connecting plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] A spring is installed in the rotating shaft, and the hinge sleeve matched with it corresponds to multiple door opening angles. During the movement of the door, the spring and the sleeve plate rub to form a damping effect. When the door is opened to the corresponding position, the spring on the hinge shaft pops out and is stuck in the corresponding slot position to realize multiple angle positioning and fixation of the door. Multiple angles can be preset according to needs. The first through groove, the groove and the second through groove are used to place the same spring. When the middle part of the spring protrudes outward and is in the slot, it can play a role of positioning and fixing. When the middle part of the spring protrudes outward and is squeezed against the sleeve plate, it can play a damping role. BRIEF DESCRIPTION OF THE DRAWINGS
