Description

Technical Field

[0001] This utility model belongs to the field of hinge technology, specifically relating to a hydraulically damped hinge. Background Technology

[0002] A hinge is a mechanical device that connects two objects and allows them to rotate relative to each other. It typically consists of a pair of metal blades and a pivot, and is widely used in structures that require opening and closing, such as doors, windows, and cabinets. Its core function is to provide stable support and flexible rotation, while also being durable and capable of bearing heavy loads.

[0003] Traditional hinges pose significant safety hazards when closing doors. Because these hinges use a simple mechanical structure, when a user forces the door to close, the door will close rapidly due to inertia. This sudden and rapid closing not only generates a lot of noise, but more importantly, it may cause the user's fingers or other parts of the body to be pinched, which is especially threatening to children and the elderly. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulically damped hinge, which aims to solve the problems mentioned in the background art.

[0011] In a preferred embodiment of this utility model, a connecting sleeve is fixedly installed on the surface of the connecting rod, and the connecting sleeve is fixedly connected to the auxiliary spring, the bottom end of the auxiliary spring being fixedly connected to the pin.

[0012] In a preferred embodiment of this utility model, a transmission rod is fixedly installed at the bottom of the piston, and a main spring is fixedly installed at the bottom of the transmission rod, with the main spring located inside the guide column.

[0013] As a preferred embodiment of this utility model, the surface of the guide post is provided with two spiral grooves for use with a mating pin, and the end of the pin passes through the spiral grooves.

[0014] As a preferred embodiment of this utility model, the first mounting sleeve has two semi-circular grooves inside for use with a mating pin, and the end of the pin is engaged inside the semi-circular groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by using a damping component to hydraulically dampen the first hinge, the speed at which the door connected to the first hinge closes is reduced, which solves the problem that the ordinary first hinge closes too quickly and is prone to safety accidents.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example

[0028] Reference Figure 1-6 This is an embodiment of the present invention, which provides a hydraulically damped hinge, comprising:

[0029] The mounting mechanism 100 includes a guide post 110, a first mounting sleeve 120 rotatably mounted on the surface of the guide post 110, a first hinge 130 fixedly mounted on the surface of the first mounting sleeve 120, a second mounting sleeve 140 rotatably mounted on the surface of the guide post 110 and located at the bottom of the first mounting sleeve 120, a second hinge 150 fixedly mounted on the surface of the second mounting sleeve 140, and a hinge ear ring 160 sleeved on the surface of the guide post 110 and used to isolate the first mounting sleeve 120 and the second mounting sleeve 140.

[0030] The buffer mechanism 200 includes a damping component 210 for buffering rotation of the first hinge 130.

[0031] The damping component 210 is used to hydraulically dampen the first hinge 130, reducing the closing speed of the door connected to the first hinge 130. This solves the problem that the ordinary first hinge 130 closes too quickly when the door is closed, which can easily lead to safety accidents. It achieves the effect of slowing down and damping the door when it closes, thereby improving the safety of the door.

[0032] Specifically, the damping component 210 includes a piston 211 slidably mounted inside the guide post 110, a connecting rod 212 fixedly mounted on the bottom of the piston 211, an auxiliary spring 213 fixedly mounted on the surface of the connecting rod 212, a pin 214 fixedly mounted on the surface of the connecting rod 212, an oil seal 215 for sealing the guide post 110, and a locking screw 216 fixedly mounted on the bottom of the oil seal 215.

[0033] Furthermore, a first oil hole is provided on the surface of piston 211, and a second oil hole is provided on the top of piston 211.

[0034] Preferably, a connecting sleeve is fixedly installed on the surface of the connecting rod 212, and the connecting sleeve is fixedly connected to the auxiliary spring 213, and the bottom end of the auxiliary spring 213 is fixedly connected to the pin 214.

[0035] The auxiliary spring 213 is fixed by a connecting sleeve.

[0036] Furthermore, a transmission rod 217 is fixedly installed at the bottom of the piston 211, and a main spring 218 is fixedly installed at the bottom of the transmission rod 217. The main spring 218 is located inside the guide post 110.

[0037] The main spring 218 is used to apply a rebound force to the transmission rod 217, which acts as a damper when the piston 211 descends.

[0038] Specifically, the surface of the guide post 110 has two spiral grooves 170 for use with the pin 214, and the end of the pin 214 passes through the spiral grooves 170.

[0039] The spiral groove 170 is used to guide the pin 214 and move it up and down, which in turn drives the piston 211 to move up and down.

[0040] Furthermore, the first mounting sleeve 120 has two semi-circular grooves inside for use with the pin 214, and the end of the pin 214 is engaged inside the semi-circular groove.

[0041] The semi-circular groove is used to drive the pin 214 to rotate and rise or fall when the first mounting sleeve 120 rotates.

[0042] In use, the piston 211, guide column 110, and oil seal 215 utilize hydraulics. The guide column 110 is filled with hydraulic oil. When the door is opened, all the hydraulic oil enters the cylinder. When the first hinge 130 closes itself, the hydraulic oil is discharged from the cylinder and flows out slowly through the second oil hole. This slow flow creates resistance, preventing the door from closing quickly.

[0043] In summary, by using the damping component 210 to hydraulically dampen the first hinge 130, the closing speed of the door connected to the first hinge 130 is reduced. This solves the problem that the ordinary first hinge 130 closes too quickly when the door is closed, which is prone to safety accidents. It achieves the effect of slowing down and damping the door when it closes, thereby improving the safety of the door.

[0044] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered. Therefore, all such modifications are intended to be included within the scope of this utility model.

Therefore, this invention is not limited to the specific embodiments, but extends to various modifications that still fall within the scope of the appended claims.
