Description

Technical Field

[0001] This utility model relates to the field of sliding door handle technology, specifically a baseless lifting sliding door handle. Background Technology

[0002] The handle mechanism is an important component on a door used to control the opening and closing of the lock.

[0003] Chinese patent CN218623711U discloses a silent handle for a sliding door, comprising a lock body, a handle, a fixed plate, and a sliding plate. The lock body contains a transmission mechanism, which includes a hinged cam and a transmission plate. The handle is connected to the cam's shaft hole. The fixed plate is fixedly connected to the lock body. The sliding plate is positioned between the fixed plate and the lock body and is connected to the transmission mechanism. Rotating the handle drives the cam, transmission rod, and sliding plate to move vertically upwards or downwards relative to the fixed plate. The cam has a slot containing a buffer plate. The buffer plate has a right-angled buffer surface extending into the cam's shaft hole. After the rotating shaft is inserted into the shaft hole, two adjacent sides of the rotating shaft contact the right-angled buffer surface. As the rotating shaft rotates with the handle, it first abuts against the right-angled buffer surface, causing the buffer plate to elastically deform, and then abuts against the inner wall of the shaft hole, driving the cam to rotate, thus preventing abnormal noise between the rotating shaft and the shaft hole.

[0004] In the above technical solution, the handle does not have an automatic springback reset function, which means that after the user opens the door with the handle, he or she needs to manually turn the handle in the opposite direction to reset the sliding plate. Under long-term heavy load, the unreset sliding plate may cause a gap between the transmission plate hook and the hook hole, which will accelerate wear or cause abnormal noise, thereby shortening the service life of the device.

[0005] Based on this, this utility model proposes a baseless lifting sliding door handle. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a baseless lifting sliding door handle, which can make the round handle spring back to its original position after rotation through the cooperation of spring and sliding block, thus improving the practicality of the device.

[0007] The technical solution to achieve the purpose of this utility model is: a baseless lifting sliding door handle, including a round handle, a rotating block movably connected inside the round handle, a square shaft movably connected inside the rotating block, and further comprising;

[0008] A circular ring is fitted onto a square shaft, and a bearing is fitted onto the square shaft. A base is fixedly connected to the circular ring and the bearing. The base is fixedly connected to a sliding door. A sliding block is slidably connected to the rotating block. The base has a convex surface, and the sliding block has a concave surface. The convex and concave surfaces are adapted to each other. A spring is fixedly connected to the sliding block, and the spring is fixedly connected inside the circular handle.

[0009] Preferably, the round handle is fixedly connected to the rotating block by a screw.

[0010] Preferably, a silicone block is movably inserted into one of the screws.

[0011] Preferably, the rotating block is fixedly connected to the square shaft by two screws.

[0012] Preferably, a shim is provided between the rotating block and the square shaft.

[0013] Preferably, the round handle, together with the base, encloses the spring, rotating block, sliding block, washer, ring, and bearing, which provides dust protection for the handle and makes it more aesthetically pleasing.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] In this invention, rotating the round handle causes the rotating block to rotate, and the sliding block rotates along with the rotating block. The concave surface of the sliding block will disengage from the convex surface of the base as it rotates, causing the sliding block to move upward and compress the spring. After releasing the round handle, the spring will push the sliding block downward to reset, so that the concave surface of the sliding block will re-align with the convex surface of the base. During this process, the rotating block will rotate along with the movement of the sliding block, causing the round handle to rotate, thereby achieving the effect of handle rebound.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved, baseless, liftable sliding door handle. The technical solution of this utility model is as follows:

[0025] like Figures 1-4 As shown, a baseless lifting sliding door handle includes a round handle 1 with an "L"-shaped cross-section. A rotating block 6 is movably connected inside the round handle 1, and a square shaft 12 is movably connected inside the rotating block 6. The handle also includes...

[0026] A circular ring 10 is fitted onto a square shaft 12. Since the square shaft 12 and the base 9 are made of metal, the circular ring 10 is used to isolate them to reduce wear and enhance their service life. A bearing 11 is fitted onto the square shaft 12. The base 9 is fixedly connected to the circular ring 10 and the bearing 11. The base 9 is fixedly connected to the sliding door. A sliding block 7 is slidably connected to the rotating block 6. The base 9 has a convex surface, and the sliding block 7 has a concave surface. The convex and concave surfaces are matched. In the static state, the convex and concave surfaces coincide. When the round handle 1 is rotated, the sliding block 7 rotates accordingly, causing the concave surface of the sliding block 7 to move away from the convex surface of the base 9. The convex surface of the base 9 pushes the sliding block 7 upward, so that the sliding block 7 moves upward while rotating. When the round handle 1 is released, the sliding block 7 is pushed downward by the action of the spring 4, so that the convex surface coincides with the concave surface again, achieving the effect of the handle rebounding and resetting. A spring 4 is fixedly connected to the sliding block 7 and is fixedly connected inside the round handle 1.

[0027] Furthermore, such as Figures 1-4 As shown, the round handle 1 is fixedly connected to the rotating block 6 by screw 2. The screw 2 makes the round handle 1 easy to disassemble and facilitates the internal maintenance of the handle.

[0028] Furthermore, such as Figures 1-4 As shown, a silicone block 3 is movably inserted into screw 2. The silicone block 3 blocks the through hole on the round handle 1, which has the effect of dust prevention and aesthetics.

[0029] Furthermore, such as Figures 2-4 As shown, the rotating block 6 is fixedly connected to the square shaft 12 by screw 2 5. The rotating block 6 and the square shaft 12 are fixed by screw 2 5. The gasket 8, base 9, ring 10 and bearing 11 located between the two are all connected together. Then the base 9 is fixed to the door.

[0030] Furthermore, such as Figures 2-4 As shown, a shim 8 is provided between the rotating block 6 and the square shaft 12. Because the base 9 and the rotating block 6 require high hardness, metal materials are selected. In order to prevent friction between metals, the shim 8 is used for isolation, thereby enhancing the service life of the base 9 and the rotating block 6.

[0031] Furthermore, such as Figures 1-4 As shown, the round handle 1, together with the base 9, encloses the spring 4, rotating block 6, sliding block 7, washer 8, ring 10 and bearing 11, which has a dustproof effect on the handle and makes the handle more aesthetically pleasing. The handle is easy to install and remove through the cooperation of screw 1 2 and screw 2 5.

[0032] The specific working method is as follows: Rotate the round handle 1 to drive the rotating block 6 to rotate. Since the sliding block 7 is slidably connected to the rotating block 6, the sliding block 7 rotates with the rotating block 6. In the stationary state, the concave surface of the sliding block 7 coincides with the convex surface of the base 9, so that when rotating, the concave surface of the sliding block 7 will disengage from the convex surface of the base 9, causing the sliding block 7 to move upward and compress the spring 4. After releasing the round handle 1, under the action of the spring 4, the sliding block 7 will be pushed downward to reset, so that the concave surface of the sliding block 7 will coincide with the convex surface of the base 9 again. During this process, the rotating block 6 will rotate with the movement of the sliding block 7, driving the round handle 1 to rotate, thereby achieving the effect of handle rebound.

[0033] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
