Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a detachable hinge with low resistance. Background Art

[0002] Traditional bearing hinges, such as a hinge with authorization announcement number CN2771431Y, have a technical solution in which the left hinge and the right hinge are connected via a rotating shaft and a bearing. Friction is easily generated between the left hinge and the right hinge during use, resulting in greater resistance to the opening and closing of the hinge.

[0003] Application No. 201710607120.1 A double ball hinge, as an improved bearing hinge, uses a gasket to reduce the friction between the two connecting leaves, but it still cannot completely solve the resistance generated during the opening and closing of the hinge. How to prevent contact and friction between the hinge leaves is the key factor in solving the hinge resistance;

[0004] Most traditional hinges are pre-installed fixed bearing hinges. During the installation process, it is often necessary to locate and drill holes in the hinge installation position on the doors and windows, and then fix the doors and windows to the fixed bearing hinges. Since doors and windows are heavy, errors are easy to occur during the positioning and drilling process, which ultimately affects the installation quality.

[0005] Therefore, we propose a detachable hinge with low resistance to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-3 The utility model provides a technical solution: a detachable hinge with low resistance, comprising: a left hinge 1 and a right hinge 2, wherein the left hinge 1 and the right hinge 2 are respectively fixed at the upper and lower ends of the connection of the door panels;

[0026] The left hinge 1 is integrally provided with a first rotating head 11, and a first through hole 111 is formed through the middle of the first rotating head 11, and the first through hole 111 is a threaded hole;

[0027] The right hinge 2 is integrally provided with a second rotating head 21, and a second through hole 211 is formed through the middle of the second rotating head 21;

[0028] The first rotating head 11 and the second rotating head 21 are staggered and overlapped, and the first through hole 111 and the second through hole 211 are overlapped, and the hole centers are coaxial;

[0029] The second through hole 211 is movably inserted with a bolt 6 from below, and the upper end of the bolt 6 is screwed and fixed with the second through hole 211;

[0030] The bolt 6 is located at the second through hole 211 and sleeved with the flange bearing 5. The flange bearing 5 enables the bolt 6 and the second through hole 211 to rotate relatively smoothly, thereby reducing the rotational friction.

[0031] A flange sheet 51 is integrally provided on the side of the flange bearing 5. The flange sheet 51 is buckled on the lower surface of the second through hole 211 from below to prevent the flange bearing 5 from moving axially.

[0032] The bolt 6 is located above the flange bearing 5, and the washer 4 and the dustproof pad 3 are movably mounted. The outer diameter of the washer 4 is close to the inner ring of the flange bearing 5. When the axis of the washer 4 and the flange bearing 5 coincide, the washer 4 only coincides with the positive projection of the inner ring of the flange bearing 5. The washer 4 and the inner ring of the flange bearing 5 are fixed to each other, which can fix the first rotating head 11 and the inner ring of the flange bearing 5 to each other. The dustproof pad 3 fits with the first rotating head 11 and rotates with the first rotating head 11 without generating friction, thereby playing the role of dust prevention and gap filling.

[0033] The installation method of the removable low resistance hinge is as follows:

[0034] The first step is to embed the flange bearing 5 into the side of the second rotating head 21 away from the first rotating head 11, and the flange 51 is tightly attached to the second rotating head 21;

[0035] The second step is to install the left hinge 1 and the right hinge 2 on the frame of the door or window respectively;

[0036] Step 3: After fixing the frame to the predetermined position, align the axes of the first rotating head 11 and the second rotating head 21, pass the bolt 6 through the flange bearing 5, then through the washer 4 and the dustproof pad 3, and screw it into the first through hole 111 of the first rotating head 11, so as to fix the hinge. At this time, the second rotating head 21 is fixed to the outer ring of the flange bearing 5, and the first rotating head 11 is fixed to the inner ring of the flange bearing 5. The first rotating head 11 and the second rotating head 21 are not in direct contact, and no friction resistance is generated except for the flange bearing 5.

[0037] According to different installation positions, the upper and lower positions of the first rotating head 11 and the second rotating head 21 can be switched to meet the convenience of tightening the bolt 6.

[0038] Embodiment 2

[0039] See also Figure 4 The utility model provides a technical solution: a detachable low-resistance hinge, comprising: a first rotating head 11, a second rotating head 21 and a bolt 6. The difference between this embodiment and the first embodiment is that a plane bearing 7 is installed between the first rotating head 11 and the second rotating head 21, and the plane bearing 7 is sleeved on the bolt 6;

[0040] The plane bearing 7 includes a bearing upper part 71 and a bearing lower part 72, and a ball assembly 73 is arranged between the bearing upper part 71 and the bearing lower part 72. The bearing upper part 71 and the bearing lower part 72 are rotationally connected through the ball assembly 73. The bearing upper part 71 is fixedly connected to the first rotating head 11, and the bearing lower part 72 is fixedly connected to the second rotating head 21, thereby realizing the articulation of the first rotating head 11 and the second rotating head 21, and the first rotating head 11 and the second rotating head 21 will not directly contact and cause wear.
