Description

Technical Field

[0001] This utility model relates to the field of handle technology, specifically a split-type profile door handle. Background Technology

[0002] Handles and levers are commonly used in building decoration and furniture making for opening and closing doors, windows, drawers, and other components.

[0003] Chinese patent CN215485230U discloses a novel door handle, including a handle with a spring fixedly installed inside. A square shaft is fixedly installed at the right end of the spring, extending to the outside of the handle. A fixing plate is sleeved on the left end of the square shaft, located to the right of the spring. A fixing seat is sleeved on the right side of the fixing plate, located on the surface of the square shaft. A base is sleeved on the surface of the right end of the square shaft. An installation groove is provided inside the handle, and the left side of the base is fixedly installed to the right side of the handle. This patent offers more convenient installation, reduces workload, lowers costs, and facilitates later maintenance. It also solves the problems of traditional door handles, such as inconvenient disassembly during installation, high installation workload, increased costs, and inconvenient later maintenance.

[0004] In the above technical solution, although the installation structure of the device is optimized, its rebound function still relies on the spring acting directly on the square shaft. This design has two shortcomings: first, the long-term compression of the spring is prone to elastic fatigue, affecting the rebound stability; second, the rigid connection between the spring and the square shaft occupies a large space, which limits the flexible selection of the handle body structure.

[0005] Based on this, this utility model proposes a split profile door handle. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a split profile door handle, which can use a spring and a sliding block to press the pivot when the handle body is released after use, so as to straighten the handle and achieve a rebound effect.

[0007] The technical solution to achieve the purpose of this utility model is: a split profile door handle, including a handle body, on which a square shaft is movably connected; and further comprising:

[0008] A rotating shaft is slidably connected to a square shaft. A lower base is sleeved on the square shaft. Multiple springs are fixedly connected inside the lower base. Two sliding blocks are fixedly connected to each of the multiple springs. The two sliding blocks are slidably connected to the lower base.

[0009] Preferably, the handle body is fixedly connected to the square shaft by a set screw.

[0010] Preferably, the rotating shaft is fixedly connected to the square shaft by a pin.

[0011] Preferably, the lower base is snapped onto the upper base.

[0012] Preferably, the upper base is fitted with a housing.

[0013] Preferably, a ring is provided between the handle body and the outer shell.

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

[0015] In this invention, through the cooperation of the lower base, spring, sliding block and rotating shaft, when the handle body is released after use, the sliding block moves inward under the action of the spring, squeezing the rotating shaft, driving the rotating shaft and square shaft to reset, so that the handle body returns to the correct direction, thereby achieving a rebound effect.

[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 split-type profile door handle. The technical solution of this utility model is as follows:

[0025] like Figures 1-4As shown, a split-type profile door handle includes a handle body 1, a square shaft 11 movably connected to the handle body 1, the top of the square shaft 11 being located inside the handle body 1, and also includes;

[0026] A pivot 8 is slidably connected to a square shaft 11. The cross-section of the pivot 8 is cross-shaped. A lower base 9 is fitted onto the square shaft 11. Multiple springs 6 are fixedly connected inside the lower base 9. The more springs 6 there are, the greater the compressive force will be when the compression space is small. The purpose is to make the space in the middle of the pivot 8 larger, so that there are more options for the handle body 1. Two sliding blocks 7 are fixedly connected to each of the multiple springs 6. The two sliding blocks 7 are symmetrical about the square shaft 11 and are slidably connected to the lower base 9. When the handle body 1 is released after use, the sliding blocks 7 move inward under the action of the springs 6, squeezing the pivot 8 and driving the pivot 8 and the square shaft 11 to return to their original positions, so that the handle body 1 returns to the correct direction, thus achieving a rebound effect.

[0027] Furthermore, such as Figure 1 and Figure 2 As shown, the handle body 1 is fixedly connected to the square shaft 11 by the set screw 2. The set screw 2 enables the handle body 1 to be quickly installed and removed.

[0028] Furthermore, such as Figures 1-3 As shown, the rotating shaft 8 is fixedly connected to the square shaft 11 by the pin 10, and the rotating shaft 8 and the square shaft 11 rotate synchronously by the pin 10.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, the upper base 5 is snapped onto the lower base 9. The upper base 5 encloses the spring 6 and the sliding block 7 inside the lower base 9, ensuring that the sliding block 7 moves stably.

[0030] Furthermore, such as Figures 1-3 As shown, the upper base 5 is fitted with a housing 4, which encloses the upper base 5 and the lower base 9, improving the aesthetics of the device.

[0031] Furthermore, such as Figure 2 and Figure 3 As shown, a ring 3 is provided between the handle body 1 and the outer shell 4. The ring 3 is used to isolate the friction between the handle body 1 and the outer shell 4 and to reduce the loosening of the handle body 1.

[0032] The specific working method is as follows: First, install the spring 6 and the sliding block 7 on the lower base 9. Then, insert the end of the rotating shaft 8 with a hole into the lower base 9. Pass the square shaft 11 through the rotating shaft 8 so that the holes of the two overlap. Use the pin 10 to fix the square shaft 11 and the rotating shaft 8. Then, put the upper base 5 on the lower base 9 and use the upper base 5 to wrap the spring 6 and the sliding block 7. Then, fix the upper base 5 and the lower base 9 on the profile door with bolts. After the installation is completed, put the outer shell 4 on the upper base 5 and cover the bolts to improve the appearance of the device. Then, put the ring 3 into the outer shell 4. Then, insert the handle body 1 into the ring 3 so that the top of the square shaft 11 is embedded in the handle body 1. Then, use the set screw 2 to fix the handle body 1 and the square shaft 11, thus completing the installation of the device. After the handle body 1 is rotated to open the door, the sliding block 7, under the action of the spring 6, squeezes the rotating shaft 8, so that the handle body 1 returns to the correct direction, thus achieving a rebound effect.

[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.
