Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 to 3, in one embodiment, there is provided a door closer 10 including:

a first hinge base 11;

the first hinge seat 11 is hinged with the second hinge seat 12 through a hinge shaft 13;

the elastic pressing component 14 is arranged on the first hinge seat 11, the elastic deformation direction of the elastic pressing component 14 is parallel to the axial direction of the hinge shaft 13, and the elastic pressing component 14 comprises a pressing part 141 capable of pressing against the second hinge seat 12 along the axial direction of the hinge shaft 13.

When the first hinge seat 11 rotates relative to the second hinge seat 12 to the state that the pressing portion 141 and the second hinge seat 12 are aligned, the pressing portion 141 presses against the second hinge seat 12, a friction force exists between the pressing portion 141 and the second hinge seat 12, and the relative position between the first hinge seat 11 and the second hinge seat 12 is fixed under the action of no external force based on the existence of the friction force.

Further, as shown in fig. 5, in an embodiment, a plurality of engaging portions 121 are disposed on the second hinge seat 12, the plurality of engaging portions 121 are spaced around the hinge shaft 13, and when the first hinge seat 11 rotates relative to the second hinge seat 12, the pressing portion 141 can be sequentially in limit-fit with each of the engaging portions 121.

According to the door closer 10 provided by the scheme, the first hinged seat 11 and the second hinged seat 12 can be respectively arranged on the door body and the box body when the door body is used, the pressing part 141 moves relative to the second hinged seat 12 along with the first hinged seat 11 in the opening and closing process of the box body, and the pressing part 141 is in limit fit with the different matching parts 121 when the door body is opened to different angles, so that the door body can be stopped at different opening angle positions to adapt to different opening angle requirements of users, and the applicability is improved. Specifically, when the first hinge seat 11 and the second hinge seat 12 rotate relatively to the pressing portion 141 and the second hinge seat 12, the elastic deformation capability of the elastic pressing component 14 enables the pressing portion 141 of the elastic pressing component 14 to always press against the second hinge seat 12, so that the pressing portion 141 and the matching portion 121 can be in limit matching when they are opposite to each other.

Specifically, as shown in fig. 5, the distance between each of the engaging portions 121 and the hinge shaft 13 is equal, and the distance is the same as the distance between the pressing portion 141 and the hinge shaft 13. Therefore, when the first hinge seat 11 and the second hinge seat 12 rotate relatively, the pressing portion 141 can be in limit fit with the fitting portion 121 through the position of the fitting portion 121.

Based on the fact that the elastic pressing component 14 can extend and contract in the direction parallel to the axial direction of the hinge shaft 13, when the pressing portion 141 is not opposite to the matching portion 121, the pressing portion 141 presses against the second hinge seat 12, and at this time, the compression amount of the elastic pressing component 14 is relatively large. When the first hinge base 11 and the second hinge base 12 rotate to the position where the pressing portion 141 is opposite to the matching portion 121, the pressing portion 141 and the matching portion 121 are in concave-convex matching, and at this time, the compression amount of the elastic pressing component 14 is relatively small. The pressing part 141 and the matching part 121 are in concave-convex matching, so that the relative position between the first hinge seat 11 and the second hinge seat 12 is fixed without the user actively pushing the door.

Optionally, in other embodiments, the pressing portion 141 and the matching portion 121 may be in a limit fit by a magnetic attraction manner, or other fitting manners capable of temporarily limiting the pressing portion 141 at the position of the matching portion 121 may be adopted.

As shown in fig. 6 to 8, the pressing portion 141 is a protrusion structure included in the elastic limiting component. When the pressing portion 141 faces the second hinge base 12, the pressing portion 141 presses against the second hinge base 12. After the pressing portion 141 is inserted into the recess, if there is no external force, the relative position between the first hinge seat 11 and the second hinge seat 12 is fixed. And a plurality of depressions are spaced around the hinge shaft 13 based on the plurality of depressions, so that there is a variety of angles at which rotation between the first hinge base 11 and the second hinge base 12 is stopped.
