Description

Technical Field

[0001] This utility model relates to the field of hardware accessories technology, specifically a novel buffer hinge. Background Technology

[0002] Currently, most common soft-close hinges on the market use springs in conjunction with hydraulic cylinders to achieve a soft-close function, but some problems still exist in actual use. For example, some hinges cannot be stably positioned when the door panel is opened to its maximum angle, causing the door panel to wobble or close unexpectedly; other hinges have an unsatisfactory soft-close effect during the closing process, easily generating impact noise and affecting the user experience. In addition, existing hinges have complex structures, and the installation and debugging process is cumbersome, which is not conducive to production efficiency and user self-adjustment.

[0003] Therefore, we propose a novel buffer hinge to address the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a novel buffer hinge to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel buffer hinge, comprising: a hinge outer shell and a hinge inner shell, wherein the hinge outer shell is fixedly installed on a door panel, the hinge inner shell is embedded within the hinge outer shell, and the hinge inner shell and the hinge outer shell are linearly limited and linearly slidably connected.

[0006] A pin is fixedly installed at the lower end of the hinge inner shell. The pin is slidably connected to the hinge hook piece. A limit hole is opened on the hinge hook piece. The limit hole is an irregularly shaped round-edged hole. The pin moves through the limit hole and the hinge hook piece is hinged to the hinge outer shell.

[0007] A buffer cylinder is installed inside the hinge inner shell. The telescopic end of the buffer cylinder is fixedly connected to the hinge inner shell, and the cylinder body of the buffer cylinder is fixedly connected to the hinge outer shell.

[0008] Preferably, two first pins pass through the inner shell of the hinge, and the outer shell of the hinge has corresponding elongated holes for limiting in the vertical direction, with the first pins slidably connected to the elongated holes for limiting.

[0009] Preferably, the lower end of the hinge hook plate movably passes through the second pin, and the second pin is rotatably connected to the hinge housing.

[0010] Preferably, the hinge housing sidewall is bent inward into a sheet-like limiting pressure plate, which is fixedly connected to the cylinder body of the buffer cylinder.

[0011] Preferably, a spring is installed between the upper end of the inner hinge shell and the outer hinge shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By using the irregularly shaped limiting holes on the hinge hook plate and the cooperation of the pin, the door panel can be reliably positioned at the maximum opening angle, preventing the door panel from shaking or closing on its own, thus improving safety.

[0014] 2. The use of a buffer cylinder and spring working together provides uniform buffering force during the door closing process, effectively slowing down the door's movement speed, reducing impact noise, and extending the hinge's service life.

[0015] 3. The inner and outer shells of the hinge adopt a linear sliding connection, combined with the limiting elongated hole and pin structure, to ensure accurate movement trajectory. The overall structure is simple and convenient for production assembly and on-site installation and debugging. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-2This utility model provides a technical solution: a novel buffer hinge, comprising: a hinge outer shell 1 and a hinge inner shell 3, the hinge outer shell 1 being fixedly installed on a door panel, the hinge inner shell 3 being embedded inside the hinge outer shell 1, and the hinge inner shell 3 and the hinge outer shell 1 being linearly limited and linearly slidingly connected, so that the hinge inner shell 3 and the hinge outer shell 1 can slide relative to each other up and down.

[0025] A spring 2 is installed between the upper end of the inner hinge shell 3 and the outer hinge shell 1, so that the inner hinge shell 3 and the outer hinge shell 1 can slide elastically relative to each other.

[0026] Two first pins 31 pass through the inner hinge shell 3, and the outer hinge shell 1 has corresponding elongated holes 11 in the vertical direction. The first pins 31 are slidably connected to the elongated holes 11, so that the inner hinge shell 3 and the outer hinge shell 1 can slide vertically relative to each other. The sliding distance is limited by the cooperation between the first pins 31 and the elongated holes 11.

[0027] A pin 32 is fixedly installed at the lower end of the hinge inner shell 3. The pin 32 is slidably connected to the hinge hook piece 6. A limit hole 62 is opened on the hinge hook piece 6. The limit hole 62 is an irregularly shaped round hole. The pin 32 moves through the limit hole 62 and the hinge hook piece 6 is fixedly installed with the box body.

[0028] The lower end of the hinge hook 6 moves through the second pin 61, and the second pin 61 is rotatably connected to the hinge housing 1 to realize the hinge connection between the hinge hook 6 and the hinge housing 1.

[0029] The hinge of the door panel and the box body is achieved by hinge hook 6 and hinge housing 1.

[0030] Example 2

[0031] Please see Figure 3-5 This utility model provides a technical solution: a novel buffer hinge, comprising: a hinge inner shell 3, a buffer cylinder 5 disposed inside the hinge inner shell 3, the telescopic end of the buffer cylinder 5 being fixedly connected to the hinge inner shell 3, the cylinder body portion of the buffer cylinder 5 being fixedly connected to the hinge outer shell 1, and a limiting pressure plate 33 being installed by bending a side wall of the hinge outer shell 1 inward, the limiting pressure plate 33 being fixedly connected to the cylinder body of the buffer cylinder 5.

[0032] Working principle: When the door panel rotates and opens relative to the box body, the second pin 61 of the hinge outer shell 1 rotates relative to the hinge hook 6, and the pin 32 of the hinge inner shell 3 slides along the limiting hole 62. When it is opened to the maximum angle, the pin 32 is stuck at one end of the limiting hole 62. The pin 32 pulls the hinge inner shell 3 to move relative to the hinge outer shell 1, the spring 2 is stretched, and the buffer cylinder 5 is stretched. At this time, the door panel is opened and fixed relative to the box body.

[0033] When the push door panel approaches the housing, the pin 32 slides along the limiting hole 62 to the other end. At this time, the spring 2 returns to its original position, and the buffer cylinder 5 begins to compress, which plays a buffering role until the spring 2 is fully returned to its original position and the door panel closes relative to the housing.

[0034] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
