However, existing self-closing hinges have the following technical problems:

1. Most existing common self-closing hinges do not have a spring tension adjustment function, and consequentially, the self-closing force of the hinges cannot be adjusted.

2. The spring tension adjustment on most existing hinges are fixed through a pin or a set screw to adjust the self-closing force, this structure requires the pin or the set screw to be removed before adjustment, and consequentially, the adjustment process is complex.

In view of this, the invention designs a hinge with an automatic tension adjustment to solve the above-mentioned problems.

Detailed Description of the Invention

To make the objectives, technical solutions and advantages of the embodiments of the invention clearer, the technical solution of the embodiments of the invention are clearly and completely described below in combination with the accompanying drawings of the embodiments. Clearly, the following embodiments are only illustrative ones, and are not all possible ones of the invention. All other embodiments obtained by those ordinarily skilled in the art on the basis of these illustrative ones without creative labor should also fall within the protection scope of the invention. Thus, the detailed description of the following embodiment, which is only a selected one of the invention, shown in the drawings is not intended to limit the protection scope of the invention. All other embodiments obtained by those ordinarily skilled in the art without creative labor should also fall within the protection scope of the invention.

It should be noted that in the description of the invention, directional or positional relations indicated by the terms such as “upper” , “lower” , “inner” , “outer” , “front end” , “rear end” , “two ends” , “one end” , and “the other end” are only for facilitating and simplifying the description of the invention, do not indicate or imply that devices or elements referred to must have a specific direction or must be configured and operated in a specified direction, and thus should not be interpreted as limitations of the invention.

It should be noted that in the description of the invention, the terms such as “install” , “arrange” and “connect” should be broadly understood, unless otherwise clearly specified. For example, “connect” may refer to fixed connection, detachable connection, or integrated connection, mechanical connection or electrical connection, direct connection or indirect connection by means of an intermediate, or internal communication of two elements. Those ordinarily skilled in the art can appreciate the specific meanings of these terms in the invention as the case may be.

Embodiment:

Referring to FIG. 1-FIG. 5, the invention provides the following technical solution: a hinge with an automatic tension adjustment comprises a right metal plate 1, wherein the left end of the right metal plate 1 is connected with a hollow rotating chamber 2, a left metal plate 3 is arranged on the left side of the hollow rotating chamber 2, hollow rotating blocks 4 are symmetrically connected to an upper portion and a lower portion of the right end of the left metal plate 3, the hollow rotating chamber 2 is located between the two hollow rotating blocks 4 and is located on the same axis as the hollow rotating blocks 4, a rotating pin 5 is inserted in the middle of the hollow rotating block 4 on the upper portion, movably connected with the hollow rotating block 4 on the upper portion and fixedly connected with the hollow rotating chamber 2, an automatic tension adjustment 6 is arranged in the hollow rotating block 4 on the lower portion, a torsion spring 7 is fixedly connected between the rotating pin 5 and the automatic tension adjustment 6, and an internal hexagonal adjustment hole is formed in the bottom center of the automatic tension adjustment 6.

Wherein, the automatic tension adjustment 6 comprises a pawl base 61, an automatic tension adjuster 62 is inserted in the lower portion of the pawl base 61, an internal hexagonal adjustment hole is formed in the top center of the automatic tension adjuster 62, an installation hole 63 is horizontally formed in the middle of the automatic tension adjuster 62, an elastic piece 64 is arranged in an inner cavity of the installation hole 63, the left and right ends of the elastic piece 64 are fixedly connected with chamfered adjustment blocks 65, the pawl base 61 is fixedly connected with the hollow rotating block 4 on the lower portion, and the tail end of the automatic tension adjuster 62 is fixedly connected with the lower end of the torsion spring 7.

During implementation, a user installs the hinge at a required location; when the self-closing tension of the hinge needs to be adjusted, the user inserts an Allen Key into the automatic tension adjuster 62 from the outside of the hinge and rotates the Allen Key to drive the automatic tension adjuster 62 to rotate below the paw base 61 to make sure that the two chamfered adjustment blocks 65 continuously make contact with the pawl base 61 similar to a ratchet, and the automatic tension adjuster 62 rotates to drive the torsion spring 7 to rotate, so that the self-closing speed of the hinge is adjusted by adjusting the torque of the torsion spring; when resetting the self-closing speed of the hinge, the user inserts the Allen Key into the automatic tension adjuster 62 and then presses the Allen Key to enable the torsion spring 7 to deform, in this process, pawls of the pawl base 61 are separated from the chamfered adjustment blocks 65 and the ratchet disengage, the torsion spring 7 restores to the normal position, and thus, the self-closing speed of the hinge is reset.

The above embodiment is only used for explaining the specific implementation principle and effects of the invention, and is not intended to limit the invention. Any skilled in the art can make amendments or modifications on the basis of the method expounded in the invention. All equivalent modification or alterations completed by those ordinarily skilled in the art without deviating from the spirit and technical idea of the invention should also be included in the claims of the invention.
