Description

Technical Field

[0001] This utility model relates to the field of door closer technology, and in particular to a double-sided sliding door closer. Background Technology

[0002] A door closer is a spring-like hydraulic device on the door frame. It works by throttling the fluid within the closer to buffer the flow, ensuring the door closes automatically, accurately, and promptly to its initial position after being opened. Most commercially available door closers are covered with a decorative cover after installation, providing both protection and aesthetics. These covers typically have a C- or U-shaped cross-section and are installed using screws, snap-fit ​​mechanisms, or sliding joints. Currently, door closers with decorative covers are only available for single-sided installation. This limits their practical application, making them unsuitable for hinge-back or hinge-side installations. In such cases, a different door closer must be selected to maintain the door's opening direction, limiting compatibility with all installation scenarios. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a double-sided sliding cover door closer with a double-sided sliding cover installation structure, which can meet the front and back installation requirements of the door closer without changing the door opening direction, and effectively improve the installation compatibility of the product.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a door closer body and a cover plate. The door closer body has a cavity coaxially arranged in the horizontal direction for installing a piston and filling hydraulic oil. The upper and lower end faces of the door closer body are provided with two symmetrical through holes for installing the door closer drive shaft. The upper and lower end faces of the door closer body are symmetrically provided with grooves at two edges that are connected to the horizontal axis of the door closer body. The cover plate is the same length as the door closer body and has symmetrical inward bending at the upper and lower ends. The inward bending is adapted to the grooves by pressing and snapping in or sliding and cutting in, so that the cover plate is fixedly installed on either the front or rear end face of the door closer body.

[0005] Furthermore, the groove is integrally die-cast with the door closer body, and the groove is composed of a long end face and a short end face, wherein the included angle between the long end face and the short end face is less than 90°.

[0006] Furthermore, the long end face is inclined from the outside inward toward the axis of the door closer body with the outer edge as the axis of rotation, and the short end face is inclined from the inside out toward the axis of the door closer body with the line intersecting the long end face as the axis of rotation, and the inclination angle is less than 30°.

[0007] Furthermore, the cover plate is made of aluminum alloy, its length is consistent with the front and rear end faces of the door closer body, its width is less than or equal to the front and rear end faces of the door closer body, and the inward bending and tilting direction is consistent with the tilting direction of the long end face.

[0008] Furthermore, the angle between the inward bend and the horizontal line is greater than the angle between the long end face and the horizontal line.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model improves upon the shortcomings of existing products in actual installation, which cannot simultaneously accommodate the installation of the door leaf on the hinge back side or the lintel on the hinge side. It symmetrically provides grooves on the upper and lower end faces of the door closer body and its two horizontally oriented edges. The inward bending at the upper and lower ends of the cover plate adapts to the grooves. The width of the cover plate is designed to be the same as or slightly smaller than the front and rear end faces of the door closer body. The cover plate is made of aluminum alloy, and with appropriate thickness, it has a certain degree of elasticity. The cover plate can be installed on either the front or rear end of the door closer body by pressing and snapping or sliding and cutting. The elasticity of the cover plate will press the inward bending of the groove to complete the fixed installation. According to the actual installation requirements of the door closer, the cover plate can be freely installed on the front or back of the door closer body, realizing the front and back installation requirements of the door closer without changing the door opening direction, effectively improving the installation compatibility of the product.

[0014] like Figures 1 to 4As shown, this utility model includes a door closer body 1 and a cover plate 2. The door closer body 1 has a cavity 3 coaxially arranged horizontally for installing a piston and filling with hydraulic oil. Two symmetrical through holes 4 are provided on the upper and lower end faces of the door closer body 1 for installing the door closer drive shaft. Grooves 5 are symmetrically arranged on the upper and lower end faces of the door closer body 1 at two edges extending along its horizontal axis. The cover plate 2 is the same length as the door closer body 1 and has symmetrically arranged inward bends 6 at its upper and lower ends. These inward bends 6 are adapted to the grooves 5 by pressing and sliding, allowing the cover plate 2 to be fixedly installed on either the front or rear end face of the door closer body 1. In this utility model, the grooves 5 are integrally die-cast with the door closer body 1. The groove 5 consists of a long end face 51 and a short end face 52, wherein the included angle between the long end face 51 and the short end face 52 is less than 90°. This utility model addresses the shortcoming of existing technologies where decorative cover plates can only be assembled on one side of the door closer body 1. Four grooves 5 are integrally die-cast on the door closer body 1, with adjacent sets of grooves 5 mirror images of each other along their horizontal centerline. By adapting the two sets of inward-curving bends 6 on the cover plate 2 to the grooves 5, and utilizing the elastic properties of the aluminum alloy material of the cover plate 2, the cover plate 2 can be freely installed on either the front or rear end face of the door closer body 1 through pressing and sliding, according to specific installation requirements. This solves the problem of traditional door closers being unable to achieve installation on the door leaf behind the hinge or on the lintel on the hinge side, thus improving the product's adaptability.

[0015] In this invention, the long end face 51 is inclined from the outside inward toward the axis of rotation of the door closer body 1, with its outer edge as the axis of rotation. The short end face 52 is inclined from the inside outward toward the axis of rotation of the door closer body 1, with the line intersecting the long end face 51 as the axis of rotation. Both inclination angles are less than 30°. The inclined arrangement of both the long end face 51 and the short end face 52 results in an L-shaped groove with a certain horizontal inclination angle in cross-section. The upper part is an open design, facilitating the pressing and sliding insertion of the cover plate 2, making installation and removal easy. The cover plate 2 is made of aluminum alloy, with a length consistent with the front and rear end faces of the door closer body 1, and a width less than or equal to the width of the cover plate. On the front and rear end faces of the door closer body 1, the inward bending direction of the inward bending 6 is consistent with the inward bending direction of the long end face 51; the angle between the inward bending 6 and the horizontal line is greater than the angle between the long end face 51 and the horizontal line. Utilizing the characteristics of aluminum alloy material, this utility model designs the width of the cover plate 2 to be less than or equal to the width of the front and rear end faces of the door closer body 1. After installation, the cover plate 2, due to its own elasticity, provides a force towards the long end face 51 for the inward bending 6, thus fixing the cover plate 2 on the door closer body 1. The angle between the inward bending 6 and the horizontal line is greater than the angle between the long end face 51 and the horizontal line, further improving the stability of the product installation.

[0016] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
