Description

Technical Field

[0001] This utility model belongs to the field of hinge technology, and specifically relates to a hinge. Background Technology

[0002] Glass doors are widely used in fields such as architectural decoration and furniture manufacturing because of their beauty and transparency. The normal use of glass doors is inseparable from the hinge, a key component. Its performance directly affects the ease of opening and closing, stability, safety and overall service life of the glass door. The hinge function enables the glass door to meet the needs of connection and rotation.

[0003] Existing hinges for glass doors cannot accurately control the opening angle when they are opened or closed, especially when the opening angle is too large. This can easily lead to over-opening, which may cause damage to the components by colliding with surrounding objects. It can also affect the convenience and safety of use, and is difficult to meet the needs of modern furniture and buildings for precise operation. Utility Model Content

[0004] The purpose of this invention is to provide a 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 hinge, comprising:

[0006] A base, on one side of which a valve body is rotatably connected;

[0007] The valve body includes a left clamp plate and a right clamp plate, which are fixed together by several adjusting bolts. A mounting block is connected to one side of the base, and the mounting block is rotatably connected to the left and right clamp plates via a rotating shaft. A positioning spring sleeve is fixedly fitted at one end of the rotating shaft inside the mounting block, and an arc-shaped block is connected to the surface of the positioning spring sleeve. The rotating shaft rotates and drives the positioning spring sleeve to rotate, so that the arc-shaped block on the surface of the positioning spring sleeve is engaged in the positioning groove provided in the mounting block.

[0008] A limiting sleeve is fitted onto the surface of the rotating shaft and connected to the mounting block to limit the rotation angle of the rotating shaft.

[0009] Preferably, the surface of the rotating shaft is connected to a limiting block, and both sides of the limiting block are planes.

[0010] Preferably, the mounting block is provided with two sets of positioning pins, and the positioning groove is located between the two sets of positioning pins.

[0011] Preferably, bushings are provided at both ends of the rotating shaft and at the rotating parts of the mounting block.

[0012] Preferably, the adjusting bolt is adjusted using an Allen wrench.

[0013] Preferably, one end of the limiting sleeve is a plane, and the rotation angle of the rotating shaft is limited when the plane of the limiting block contacts the plane of one end of the limiting sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The hinge of this utility model can accurately control the opening and closing angle of the glass door through the design of the limiting sleeve and the limiting block. When the door is opened, the rotating shaft rotates to 90 degrees, and the plane of the limiting block contacts the plane of one end of the limiting sleeve. At this time, the plane of the limiting block coincides with the plane of the limiting sleeve, which plays a limiting role. This effectively avoids the glass door from being opened and closed too much, prevents it from colliding with surrounding objects and being damaged, improves the safety during use, and also enhances the stability of the hinge when opening and closing, making the operation smoother.

[0016] (2) When closing the door, the valve body drives the rotating shaft and the positioning spring sleeve to rotate to 0 degrees. The arc-shaped block on the surface of the positioning spring sleeve is inserted into the positioning groove between the two sets of positioning pins in the mounting block. Through this precise hinge opening and closing positioning design, it is ensured that the hinge can be closed accurately when opening and closing, avoiding the situation where the glass door or cabinet door shakes or cannot be completely closed after the hinge is closed. This improves the sealing performance and overall aesthetics of the glass door or cabinet door, and brings a better user experience. Attached Figure Description

[0025] 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.

[0026] This utility model provides, for example Figure 1-7 A hinge shown includes:

[0027] Base 1, with valve body 2 rotatably connected to one side of base 1;

[0028] The valve body 2 includes a left clamping plate 3 and a right clamping plate 4. The left clamping plate 3 and the right clamping plate 4 are fixed together by several adjusting bolts 5. The base 1 is connected to a mounting block 6 on one side, and the mounting block 6 is rotatably connected to the left clamping plate 3 and the right clamping plate 4 through a rotating shaft 7. A positioning spring sleeve 8 is fixedly fitted on one end of the rotating shaft 7 inside the mounting block 6, and an arc-shaped block 9 is connected to the surface of the positioning spring sleeve 8. The rotating shaft 7 rotates and drives the positioning spring sleeve 8 to rotate, so that the arc-shaped block 9 on the surface of the positioning spring sleeve 8 is engaged in the positioning groove 10 provided in the mounting block 6.

[0029] A limiting sleeve 11 is fitted onto the surface of the rotating shaft 7 and connected to the mounting block 6, and is used to limit the rotation angle of the rotating shaft 7.

[0030] The rotating shaft 7 is connected to a limiting block 12, and both sides of the limiting block 12 are planes.

[0031] The mounting block 6 is provided with two sets of positioning pins 13, and the positioning groove 10 is located between the two sets of positioning pins 13.

[0032] Both ends of the rotating shaft 7 and the rotating parts of the mounting block 6 are provided with bushings 14. The bushings 14 can effectively reduce the friction between the rotating shaft 7 and the mounting block 6, reduce the degree of wear, ensure that the rotating shaft 7 can rotate smoothly, and extend the service life of the hinge.

[0033] The adjusting bolt 5 is adjusted using an Allen wrench 15.

[0034] One end of the limiting sleeve 11 is a plane, and when the plane of the limiting block 12 contacts the plane of one end of the limiting sleeve 11, it limits the rotation angle of the rotating shaft 7.

[0035] The hinge connects the base 1 to the door frame. Adjusting bolts 5 are passed through mounting holes on the door body and screwed into threaded holes on the surfaces of the left and right clamping plates 3 and 4 to secure the hinge. Figure 6 As shown, when the door needs to be opened, external force acts on the valve body 2 through the door, causing the valve body 2 to rotate relative to the base 1 around the rotating shaft 7. During the rotation of the rotating shaft 7, the positioning spring sleeve 8, which is fixedly mounted on one end of the mounting block 6, rotates together. As the rotating shaft 7 rotates, the limiting block 12 also rotates. When the rotating shaft 7 rotates to 90 degrees, the plane of the limiting block 12 contacts the plane of one end of the limiting sleeve 11. Since the limiting sleeve 11 is fixed on the mounting block 6, the limiting sleeve 11 blocks the rotation of the rotating shaft 7, restricting the rotating shaft 7 from continuing to rotate, thereby achieving precise limiting of the opening angle of the glass door and keeping the glass door stably in the 90-degree open state.

[0036] like Figure 5 As shown, when the door is closed, an external force is applied to the valve body 2, causing the valve body 2 to drive the rotating shaft 7 to rotate in the opposite direction. The rotating shaft 7 drives the zero-degree positioning spring sleeve 8 to rotate together. When it rotates to 0 degrees, the arc-shaped block 9 on the surface of the positioning spring sleeve 8 is precisely engaged in the positioning groove 10 between the two sets of positioning pins 13 in the mounting block 6. The cooperation between the arc-shaped block 9 of the positioning spring sleeve 8 and the positioning groove 10 provides accurate closing positioning for the door, enabling the glass door to close stably and accurately and remain closed, avoiding shaking after closing.

[0037] If the hinge needs to be adjusted to accommodate different door closing angles, an Allen wrench 15 can be used to operate the adjusting bolt 5. Since the hinge body 2 is fixed by the left clamping plate 3 and the right clamping plate 4 through the adjusting bolt 5, rotating the adjusting bolt 5 with the Allen wrench 15 will change the distance between the left and right clamping plates 4. If the distance is increased, the movement space and constraint of the rotating shaft 7 between the clamping plates will change, and the rotation trajectory of the rotating shaft 7 will also change when the door is closed. For example, if the door is just closed when the rotating shaft 7 rotates to 0 degrees, after increasing the clamping plate distance, the rotating shaft 7 may need to rotate a little more (within ±3 degrees) to close the door. The same applies to the opposite. This is because the change in the clamping plate distance changes the support point and force distribution of the rotating shaft 7, causing the rotation angle of the rotating shaft 7 and the closing position of the door to change in a related way. Therefore, the 0-degree closing position can be adjusted by rotating the adjusting bolt 5 with the Allen wrench 15, and the adjustment range of the 0-degree closing position is ±3 degrees.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
