Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hinge with adjustable torque. Background Art

[0002] A hinge is a connector used to connect two objects and allow the two objects to rotate relative to each other. In order to allow the two objects to automatically reset, a spring is set inside the hinge, and the two objects are reset by the torque of the spring. The torque of the hinge produced is pre-set when it leaves the factory and cannot be adjusted. However, in actual applications, the torque required for automatic reset between different objects is different. Fixed hinges cannot meet the on-site assembly requirements, resulting in low on-site construction and assembly efficiency. Therefore, the hinge needs to be able to change the torque of the spring according to demand; therefore, it is necessary to propose a hinge with adjustable torque. Utility Model Content

[0017] The following is a further description of the torque-adjustable hinge of the present invention through embodiments and in conjunction with the accompanying drawings.

[0018] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0019] In the present invention, unless otherwise clearly specified or limited, the terms "connected", "fixed" and the like should be understood in a broad sense.

[0020] For example, "fixed" can be fixed connection, detachable connection, or integrated; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through an intermediate medium, can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] See also Figures 1 to 3As shown, the utility model proposes a hinge with adjustable torque, which is characterized in that it includes hinge pieces 1 that are hingedly connected to each other, a rotating shaft 2 installed between the hinge pieces 1 to enable it to rotate flexibly, and an adjusting component that can adjust the torque is also installed on the rotating shaft 2. The adjusting component includes an adjusting seat 30 installed on the rotating shaft 2, an elastic member 31 installed on the rotating shaft 2, one end of which is connected to the adjusting seat 30 and the other end of which is connected to the left hinge 1. The adjusting seat 30 is provided with a through hole 32 for the rotating shaft 2 to pass through, and the adjusting seat 30 is provided with a limiting groove 33 for facilitating the limiting of the elastic member 31. The joint seat 30 is also provided with a plurality of adjustment holes 34 for adjusting the torque of the elastic member 31. The elastic member 31 can be selected from a spring or a hardware component with an elastic structure. The hinge piece 1 is provided with a limiting portion for limiting the adjustment seat 30. The adjustment seat 30 is provided with a slot 36 that cooperates with the limiting portion. The hinge piece 1 is provided with a plurality of mounting holes 40. Through the setting of the adjustment component, during the actual use of the hinge, it can be adjusted according to the torque required by the object to achieve the optimal state. The problem that the fixed torque cannot be adjusted is solved, the product installation efficiency is improved, and the applicability is strong.

[0022] The limiting part includes a base 37 installed on the hinge piece 1, a limiting pin 38 installed on the base 37 and connected to the slot 36, and a spring 39 installed on the base 37 and the limiting pin 38 to elastically lock the limiting pin 38 and the slot 36; through the setting and cooperation of the adjustment seat 30 and the limiting part, the adjustment seat 30 and the limiting part are locked and locked to prevent the adjustment seat 30 from slipping and causing torque balance, thereby improving the stability of the adjustment seat 30 and improving the safety of product use; through the setting of the spring 39, the limiting pin 38 is always pressed against the slot 36, thereby ensuring the safety of the adjustment seat 30.

[0023] When the utility model is used, firstly, one side of the hinge piece 1 is installed on the door frame by passing the screw through the mounting hole 40, and the other side is installed on the rotating door. Then, a tool is used to insert the adjustment hole 34 and rotate the adjustment seat 30 to the left. The adjustment seat 30 will squeeze the limit pin 38 during the rotation process, so that the spring 39 is squeezed and contracted, thereby causing the limit pin 38 to disengage from the slot 36. When the adjustment seat 30 rotates to a certain angle, the limit pin 38 is in the next slot 36, and the spring 38 is no longer squeezed. The limit pin 38 is pressed against the next slot 36 by the rebound force of the spring 39, and the adjustment seat 30 is limited and locked; when it is necessary to reset the adjustment seat 30, it is only necessary to pull the limit pin 38 outward to disengage the limit pin 38 from the slot 36. At this time, the adjustment seat 30 is quickly reset to the initial state under the action of the elastic member 31.

[0024] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
