Detailed Implementation

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0016] The following is combined Figures 1 to 8 The embodiments of this utility model are described below.

[0017] This embodiment relates to a handle base and a handle.

[0018] Reference Figures 1 to 5 This embodiment of a handle base includes a base 1, a limiting spring 2, a limiting ball 3, a gear rotating shaft 4, and a square fixing sleeve 5. The base 1 has a first recessed platform 101, a first through hole 105, a mounting hole 102, and a spring groove 103. The lower surface of the base 1 has an upward-facing first recessed platform 101, and the bottom surface of the first recessed platform 101 has a first through hole 105. The first recessed platform 101 accommodates the lower end of the gear rotating shaft 4. The diameter of the lower end of the gear rotating shaft 4 is larger than the diameter of the first through hole 105, and the upper end of the gear rotating shaft 4 passes through the first through hole 105. The mounting holes 102 are symmetrically arranged on both sides of the first recessed platform 101. The center distance of 2 is 20mm; the spring grooves 103 are symmetrically arranged on both sides of the first recessed platform 101, the spring grooves 103 are connected to the recessed platform, the limiting spring 2 is compressed and clamped in the spring groove 103, and the limiting ball 3 is provided near the top of the first recessed platform 101; the lower end of the gear rotating shaft 4 is provided with a limiting groove 402, the limiting groove 402 is used to accommodate one end of the limiting ball 3, the lower surface of the gear rotating shaft 4 is provided with an upward-facing first square blind hole 403, the first square blind hole 403 is used to accommodate a square shaft; the square fixing sleeve 5 is sleeved on the upper end of the gear rotating shaft 4, the square fixing sleeve 5 is used to fix the gear rotating shaft 4.

[0019] The design of the embodiment structure makes the handle base simple and compact, facilitating installation. Specifically, first, the limiting ball 3 is installed at the top of the spring groove 103, then the spring is installed into the spring groove 103. The spring force pushes the limiting ball 3 between the first recess 101 and the spring groove 103. Then, the gear rotating shaft 4 is installed into the base body 1 from bottom to top, and the limiting groove 402 on the gear rotating shaft 4 engages with the limiting ball 3. Then, the square fixing sleeve 5 is fitted onto the gear rotating shaft 4 for fixation. Through the rotation of the gear rotating shaft 4, the limiting groove 402 engages with the limiting ball 3, which can position the rotation angle of the gear rotating shaft 4. The 20mm hole spacing of the mounting holes allows the handle base to be used with simple system windows and inward-opening and tilt-and-turn windows.

[0020] Reference Figures 1 to 3 In some embodiments, the gear rotating shaft 4 includes, from bottom to top, a gear portion 41, an extension portion 42, and a square portion 43. The gear portion 41 is provided with the limiting groove 402. The upper end of the first square blind hole 403 is located at the extension portion 42. The square fixing sleeve 5 is sleeved on the square portion 43. The lower surface of the square fixing sleeve 5 abuts against the upper surface of the extension portion 42. The handle base also includes screws. The upper surface of the square portion 43 is provided with a downward-facing first screw hole 401. The upper surface of the square fixing sleeve 5 is provided with a downward-facing second countersunk. The bottom surface of the second countersunk is provided with a second through hole. The first screw 8 passes through the second countersunk and the second through hole and is fixed in the first screw hole 401.

[0021] Reference Figure 1 and Figure 3 The gear shaft 4 and the square fixing sleeve 5 are fixed by the first screw 8 passing through the second countersunk and the second through hole and then fixing it in the first screw hole 401. This effectively restricts the axial displacement of the gear shaft 4, improves the stability of the handle base structure, and the upper end of the first screw 8 is located inside the second countersunk, so it does not affect the shape of the square fixing sleeve 5, which is convenient for installation with the handle 7. Specifically, the gear shaft 4 is first installed in conjunction with the base 1 from bottom to top, then the square fixing sleeve 5 is fitted onto the upper end of the gear shaft 4 from top to bottom, and then the first screw 8 is passed through the second countersunk and the second through hole and tightened in the first screw hole 401, thus fixing the gear shaft 4.

[0022] Reference Figures 3 to 5 In some embodiments, the base 1 is further provided with fixing holes 104, which are symmetrically arranged on both sides of the first recessed platform 101. The mounting hole 102 is located between the fixing hole 104 and the spring groove 103. Providing fixing holes 104 helps to increase the stability of the handle base installation. At the same time, the mounting hole 102 is located between the fixing hole 104 and the spring groove 103, making the base 1 structure compact.

[0023] Reference Figure 5 In some embodiments, the number of limiting grooves 402 is 4, 6, 8, or 12. Depending on the handle rotation gear requirements in different scenarios, gear shafts 4 with different numbers of limiting grooves 402 can be used to achieve multi-angle positioning of the handle and improve the adaptability of the handle base.

[0024] Reference Figure 1 and Figure 3In some embodiments, the handle base further includes a cover 6 and a first washer 91. The cover 6 is fitted onto the base body 1. The cover 6 has a third through hole 601 through which the gear shaft 4 passes. The upper surface of the base body 1 has a third recess. The lower end of the first washer 91 is located on the third recess. The edge of the first washer 91 fits against the edge of the second through hole. The first washer 91 is located between the base body 1 and the square fixing sleeve 5. The cover 6, fitted onto the base body 1, provides physical protection for core components such as the limiting spring 2 and the limiting ball bearing 3 inside the base body 1, effectively isolating external dust, moisture, and foreign objects, reducing component corrosion and wear, extending the life of the base body 1, and improving the cleanliness of the base's appearance. The first washer 91, located between the base body 1 and the square fixing sleeve 5, prevents the square fixing sleeve 5 from rubbing against the base body 1 when rotating with the gear shaft 4, thus avoiding scratches or abnormal noises. The first washer 91 can be stably fixed by the structure design of the third recessed platform on the upper surface of the base 1 and the edge of the first washer 91 fitting into the second through hole of the base cover 6. Specifically, the first washer 91 can be made of materials such as copper or plastic.

[0025] Reference Figures 6 to 8 This embodiment of a handle includes the aforementioned handle base and a handle 7. The handle 7 includes a flat-head screw 71 and a second square blind hole 702 for accommodating the square fixing sleeve 5. The handle 7 also has a second screw hole 701 communicating with the second square blind hole 702. The flat-head screw 71 passes through the second screw hole 701 and abuts against the side wall of the square fixing sleeve 5. In the prior art, screw holes are commonly used to fix the handle 7 and the base by tightening screws into these holes. In the prior art, screws are often used to fix the handle base and handle 7 by passing through the bottom surface of the handle 7, concentrating the force mainly on the screw, making installation cumbersome and unstable. This embodiment uses a flat-head screw 71 against the side wall of the square fixing sleeve 5, eliminating the need for holes, improving the handle's adaptability, facilitating assembly, and making the handle base more stable under stress. In use, rotating the handle 7 causes the square fixing sleeve 5 to rotate, which in turn causes the gear rotating shaft 4 to rotate. The limiting groove 402 of the gear rotating shaft 4 cooperates with the limiting ball 3 to position the rotation angle, meaning that there is positioning feedback when rotating the handle 7.

[0026] Reference Figure 6 and Figure 7In some embodiments, the handle further includes a second washer 92. The lower surface of the handle 7 has an upward-facing fourth recess, and the second square blind hole 702 is located on the bottom surface of the fourth recess. The fourth recess is used to accommodate the upper end of the second washer 92. The second washer 92 separates the seat cover 6 from the handle 7, reducing frictional wear between the handle 7 and the seat cover 6 during rotation and lowering operating noise. Specifically, the second washer 92 can be made of materials such as copper or plastic.
