Detailed Implementation

[0022] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please see Figures 1-9 These are schematic diagrams of the positioning handle of this utility model, as well as its installation and usage states.

[0025] As shown in the figure, this utility model embodiment provides a handle with positioning, the overall structure of which includes a base 1, a transmission component 2 and a handle 3. The base 1 is installed in the profile, and the transmission component 2 is assembled in the base 1. The transmission component 2 includes a gear shaft 21 and a transmission rack 22. The handle 3 is connected to the gear shaft 21. The handle 3 rotates to synchronously drive the transmission rack 22 to move. The gear shaft 21 is also provided with a positioning groove 211. Positioning steel balls 212 and springs 213 are respectively provided on both sides of the gear shaft 21, so that the positioning steel balls 212 can be inserted into different positioning grooves 211 under the elastic force of the springs 213 to achieve different operating angle positioning.

[0026] In one possible implementation, the handle 3 engages with the gear shaft 21 via an internal square groove 31 and is connected via a connecting screw 32.

[0027] During installation, the gear shaft is inserted into the internal square groove of the handle for initial positioning, and then further secured by connecting screws.

[0028] The handle transmission mechanism of this utility model adopts a transmission method of gear shaft and transmission rack cooperation. Moreover, this transmission structure can effectively reduce the exposure of parts and form a similar hidden form after installation. It has a wide range of applications, can meet the power transmission requirements of large-size, multi-locking window type, and has a longer service life.

[0029] The handle of this utility model achieves different angle positioning by cooperating with positioning grooves at different positions on the gear shaft through positioning steel balls. This enables the handle to have a positioning function. Furthermore, the positioning steel balls work in conjunction with springs, resulting in stronger positioning force and enabling positioning at different operating angles, thus optimizing the feel.

[0030] In one possible implementation, a lower groove 11 for accommodating the handle is also provided on the top surface of the base 1.

[0031] The recessed design allows the handle to be hidden inside the base, achieving a near-hidden effect after installation and making the visual effect simpler and more transparent.

[0032] Among them, such as Figure 3 As shown, A represents the state during the handle's movement, while B represents the handle's open and closed states.

[0033] In one possible implementation, the bottom of the transmission rack 22 is also provided with a lubrication groove 221.

[0034] See Figure 6 As shown, by setting up a lubrication groove, lubricating oil can be added into the lubrication groove, which can reduce friction during transmission, reduce wear, and extend service life.

[0035] In one possible implementation, spring slots 12 and positioning ball slots 13 are respectively provided on both sides of the base 1 relative to the gear shaft 21.

[0036] The spring is fixed in the spring slot, and the positioning ball is fixed in the positioning ball slot, so that the positioning ball and the spring can be kept in the same straight horizontal position, avoiding the positioning ball from shifting due to the spring force, and the positioning force is stronger and more stable.

[0037] In one possible implementation, a bushing 4 is also provided between the handle 3 and the gear shaft 21. The bushing design effectively reduces wear between hardware components during transmission, extending the product's service life.

[0038] In one possible implementation, a cover 5 is also provided on one side of the base 1. The cover 5 is fixed to one side of the base 1, and the cover can cover the transmission components and other parts inside the base, making the overall appearance of the product simpler and more beautiful.

[0039] Based on the positioning handle structure design of this utility model, the assembly steps of the handle are as follows:

[0040] 1. First, install the positioning steel ball and spring into the positioning steel ball slot and spring slot of the base;

[0041] 2. Place the bushing into the corresponding hole in the base, then place the handle in, and then pass the gear shaft through the square groove of the base and the handle to fit. Finally, use the connecting screws to lock the handle, base, gear shaft and other accessories.

[0042] 3. Apply lubricating oil to the lubrication groove of the transmission rack, and then mate the transmission rack with the gear from step 2;

[0043] 4. Finally, connect the cover to the base from step 3 using fixing screws.

[0044] The installation sequence of the handles is as follows:

[0045] 1. Insert the handle into the opening of the ultra-narrow fan profile and tighten the fan profile 200 and handle with screws to complete the handle installation (see...). Figure 8 )

[0046] 2. Insert the aluminum connecting rod 500, transmission device 400, and other accessories into the slot of the fan profile 200 in sequence. Finally, insert the transmission device into the transmission rack slot of the handle and fix the transmission device with screws to complete the entire handle installation (see...). Figure 8 , Figure 9 (As shown).

[0047] The entire installation process is very convenient and quick, especially since the transmission device has a quick-installation structure.

[0048] This utility model, in conjunction with the accompanying drawings, provides a detailed description of the positioning handle. The positioning handle includes a base, a transmission assembly, and a handle. The base is installed within the profile, and the transmission assembly is assembled within the base. The transmission assembly includes a gear shaft and a transmission rack. The handle is connected to the gear shaft; rotation of the handle synchronously drives the transmission rack. The gear shaft also has a positioning groove, and positioning steel balls and springs are respectively provided on both sides of the gear shaft. Under the action of the spring force, the positioning steel balls are engaged in different positioning grooves to achieve positioning at different operating angles. This utility model's positioning handle can meet the usage scenarios of extremely narrow profiles on the market. Through the coordinated positioning of the positioning groove, positioning steel balls, and springs, positioning at different operating angles can be achieved, and the positioning force is stronger and more stable. The gear transmission structure effectively reduces exposed parts, creating a near-hidden effect after installation, and the handle can be hidden in the groove under the base, making the visual effect simpler and more transparent.

[0049] In addition, the transmission rack with lubrication groove design can reduce friction during transmission, reduce wear, and extend service life. Furthermore, the bushing design between the handle and the gear shaft can also effectively reduce wear on the hardware during transmission.
