[0037] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and 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 making creative work are within the scope of protection of the utility model.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] Example 1

[0040] like Figure 1-Figure 5As shown, the present solution specifically discloses a handle assembly, wherein the handle assembly includes a transmission device 1, a connection assembly 3 and a handle 2, and the transmission device 1 includes a transmission member 10 and a lock housing 15. During the installation process, the transmission member 10 needs to be installed into the lock housing 15, and then the lock housing 15 is first inserted into the fan profile 4, and fixedly matched with the fan profile 4 through the installation panel 16 on one side of the lock housing 15, and a transmission bar is installed in the transmission device 1, and the transmission member 10 cooperates with the transmission bar, so that the transmission member 10 will drive the transmission bar to be stored or extended to both ends during the rotation process, and the specific transmission member 10 is a gear, and the transmission bar is a rack. During the reciprocating movement of the transmission bar, the transmission bar will drive the lock point to move, so as to achieve the purpose of unlocking or locking.

[0041] In order to rotate the transmission member 10 in the transmission device 1, it is necessary to insert a connecting assembly 3 on the transmission member 10 to link with the handle 2 outside the fan profile 4. The connecting assembly 3 includes a connecting member 30 and a locking member 31, wherein the function of the connecting member 30 is to connect the transmission member 10 in the transmission device 1 with the handle 2, and the function of the locking member 31 is to connect the connecting member 30 with the transmission member 10, and the connecting member 30 is also divided into a first end 301 and a second end 302 at both ends, wherein the second end 302 is inserted into the transmission member 10 and is connected to the transmission member 10 through the locking member 31. The first end 301 is connected to the fan profile 4 to ensure that the connecting component 3 can drive the transmission component 10 to rotate during the rotation process, and the first end 301 passes through the fan profile 4 and extends to the outside of the fan profile 4 to connect with the handle 2. Specifically, a fixing hole 20 is provided on the handle 2, and the fixing hole 20 is connected to the outside, and the bottom of the fixing hole 20 is connected to the first end 301. When installing, the fixing member 21 is installed in the fixing hole 20. The fixing member 21 can be a top screw or a screw. By tightening the fixing member 21 to the first end 301, the first end 301 is fixed. Of course, the connection between the first end 301 and the handle 2 can also be an interference fit, or other fixing methods.

[0042] Specifically, Figure 4 Part D and Figure 5 As shown in the D part, a first connection hole 300 is provided on the side wall of one end of the connecting member 30 that cooperates with the transmission member 10. The first connection hole 300 is a threaded hole. Before installing the connecting member 30 to the transmission member 10, the locking member 31 needs to be installed in the first connection hole 300. Specifically, the locking member 31 is an adjusting screw. At this time, the locking member 31 needs to be completely placed in the first connection hole 300. Then, the connecting member 30 is inserted into the transmission member 10. At this time, the tool needs to be extended from the opening of the lock housing 15 into one side of the transmission member 10, and the locking member 31 is screwed outward along the second connection hole 12, so that the locking member 31 protrudes outward and presses or blocks against the second connection hole 12, thereby realizing the connection between the connecting member 30 and the transmission member 10 and forming a whole that can rotate synchronously.

[0043] One end of the handle 2 is a mounting portion, and the other end is a gripping portion. During the installation process, the mounting portion is fitted onto the outward end of the connecting assembly 3. A screw hole is also provided on the side wall of the mounting portion. The fixing member 21 is inserted into the screw hole from the outside of the mounting portion and is tightened against the outward end of the connecting assembly 3, thereby achieving the fixation of the handle 2 and the connecting assembly 3. At the same time, a guide groove extending along the axis is also provided at the outward end of the connecting assembly 3, and a guide bar cooperating with the guide groove is also provided on the mounting portion. During the cooperation process between the handle 2 and the connecting assembly 3, the guide groove and the guide bar are clamped and matched with each other, thereby preventing the axial rotation between the mounting portion and the connecting assembly 3 from occurring during the rotation of the handle 2, thereby greatly improving the stability during the working process.

[0044] In order to prevent the connection component 3 from rubbing against the fan profile 4 during rotation, a shaft sleeve 5 is sleeved on the periphery of the connection component 3, and during the installation of the connection component 3, the shaft sleeve 5 is fixedly matched with the fan profile 4. Therefore, during the rotation of the connection component 3, the connection component 3 is separated from the fan profile 4 by the shaft sleeve 5, so there is no friction with the fan profile 4, thereby reducing the loss of the connection component 3.

[0045] Example 2

[0046] like Figure 1-Figure 2 as well as Figure 6-Figure 8 As shown, the difference between this embodiment and embodiment 1 lies in the matching mode between the connecting component 3 and the transmission 1, and the rest will not be described in detail.

[0047] The locking member 31 in this embodiment is also pre-installed in the first connecting hole 300, and a docking hole 13 opposite to the second connecting hole 12 is provided on the side of the mounting hole 11 away from the second connecting hole 12. Specifically, the first connecting hole 300 is a threaded hole, and the second connecting hole 12 is a through hole. When the locking member 31 is tightened and adjusted by a tool, as shown in FIG. Figure 7 As shown in part A of the embodiment, the locking member 31 is rotated toward the docking hole 13 until the locking member 31 is inserted into the docking hole 13. At this time, the locking member 31 cannot go any further after docking with the docking hole 13. When the locking member 31 is further rotated, the locking member 31 and the docking hole 13 are pressed against each other, and the connecting member 30 is pressed toward the second connecting hole 12. In this way, a clamping connection is achieved, so that the transmission member 10 and the connecting member 30 are connected as a whole. When the connecting member 30 rotates, the transmission member 10 can be driven to rotate together, and the matching effect is better than that of Example 1.

[0048] Example 3

[0049] like Figure 9-10As shown, the difference between this embodiment and embodiment 1 lies in the matching mode between the connecting component 3 and the transmission 1, and the rest will not be described in detail.

[0050] A first connection hole 300 is provided on the side wall of one end of the connecting member 30 that cooperates with the transmission member 10, and a second connection hole 12 is provided on the transmission member 10, wherein the first connection hole 300 is a threaded hole connected to the locking member 31. Before the connecting member 30 is installed, the locking member 31 is placed outside the fan profile 4, such as Fig.10 As shown in part B, after the connecting member 30 is inserted into the transmission member 10, the second connecting hole 12 and the first connecting hole 300 are opposite to each other, so the connecting assembly 3 is connected to the outside through the second connecting hole 12 and the first connecting hole 300. At this time, the locking member 31 is passed through the second connecting hole 12 to cooperate with the transmission member 10, and the front end of the locking member 31 is inserted into the first connecting hole 300 to connect and cooperate with the connecting member 30, and the end of the locking member 31 is pressed against the second connecting hole 12, thereby realizing a fixed connection between the connecting member 30 and the transmission member 10. Compared with embodiments 1 and 2, this cooperation mode can adjust the locking member 31 by penetrating into the second connecting hole 12 from the outside, thereby improving the convenience of adjustment.

[0051] Example 4

[0052] like Fig.11 As shown, the difference between this embodiment and embodiment 1 lies in the matching mode between the connecting component 3 and the transmission 1, and the rest will not be described in detail.

[0053] A first connection hole 300 is provided on the side wall of one end of the connecting member 30 that cooperates with the transmission member 10, and a second connection hole 12 is provided on the transmission member 10, wherein the second connection hole 12 is a threaded hole connected to the locking member 31. Before the connecting member 30 is installed, the locking member 31 is placed outside the fan profile 4, such as Fig.11 As shown in part C, when the connecting member 30 is inserted into the transmission member 10, the locking member 31 is threadedly engaged with the second connecting hole 12, and the front end of the locking member 31 is inserted into the first connecting hole 300 and pressed against the connecting member 30. Specifically, the first connecting hole 300 is a concave hole, and a fixed connection between the connecting member 30 and the transmission member 10 is achieved in this way.

[0054] Example 5

[0055] like Figure 12-13 As shown, this embodiment also discloses the structure and fixing method of the supporting assembly 6.

[0056] The transmission 1 includes a lock housing 15 and an installation panel 16 disposed on one side of the lock housing 15. During installation, the lock housing 15 needs to be inserted into the fan profile 4 first, and the installation panel 16 is placed outside the fan profile 4. The installation panel 16 is fixedly connected to the fan profile 4. At this time, there are gaps on both sides of the lock housing 15 and the fan profile 4. Therefore, during the rotation of the handle 2, the lock housing 15 will be pushed by the handle 2 and thus deflected to the gaps on both sides. After a period of use, the position of the transmission 1 will be offset, thereby affecting the stability of the transmission 1. Therefore, it is necessary to install a support assembly 6 on the transmission 1 so that the transmission 1 can be pressed against both sides of the fan profile 4 to offset the gap between the transmission 1 and the fan profile 4.

[0057] A third through hole is provided at both ends of the lock housing 15, and a supporting assembly 6 is provided in the third through hole. A rotating hole 60 for controlling the expansion of the supporting assembly 6 is provided in the supporting assembly 6, and the rotating hole 60 is connected to the outside. Therefore, after the actuator 1 is installed on the fan profile 4, the rotating hole 60 can be rotated by inserting a wrench into the rotating hole 60 from the outside. By rotating the rotating hole 60, the supporting assembly 6 can be expanded outward along the third through hole and tightly connected with the left and right ends of the fan profile 4, thereby offsetting the gap between the lock housing 15 and the fan profile 4. In this way, the lock housing 15 is partially tightened and fixed, thereby preventing the lock housing 15 from swinging to the sides of the fan profile 4, and improving the overall stability of the actuator 1.

[0058] Specifically, the top support assembly 6 includes a shift block 61 and top support blocks 62 installed on both sides of the shift block 61; wherein the shift block 61 is connected to the rotating shaft of the transmission device 1, and the rotating hole 60 is arranged in the middle of the shift block 61, and the top support block 62 is movably connected with the third through hole. The shift block 61 drives the top support block 62 to move along the third through hole. When the shift block 61 is pushed outward, the top support block 62 moves outward of the third through hole. When the shift block 61 is pushed inward, the top support block 62 will be pushed inward by the shift block 61 so that the top support block 62 moves into the third through hole.

[0059] Specifically, the shift block 61 is in the shape of an elongated strip, and the rotating shaft of the shift block 61 is rotatably matched with the middle part of the third through hole. Therefore, the working state of the shift block 61 is as follows: in the closed state, the long side of the shift block 61 is parallel to the long side of the lock shell 15; in the tightened state, the long side of the shift block 61 is inclined at an angle to the long side of the lock shell 15, and the two ends of the shift block 61 tighten the supporting block 62 outward.

[0060] It is necessary to explain in detail how the shift block 61 drives the supporting block 62 to move into the third through hole, wherein both ends of the shift block 61 are provided with limit surfaces 63, and the supporting block 62 is provided with a limit block 64. The shift block 61 gradually rotates inward, and the limit surfaces 63 and the limit blocks 64 press against each other. As the shift block 61 continues to move, the limit surfaces 63 and the limit blocks 64 will press more tightly, thereby driving the limit blocks 64 to continuously move into the third through hole.

[0061] In addition, in order to make the shift block 61 move more smoothly during the process of pushing outward, a first arc surface 65 is provided at the corner of the shift block 61, and a second arc surface 66 cooperating with the first arc surface 65 is provided at both ends of the supporting block 62. In the pushing state, the shift block 61 pushes the supporting block 62 outward through the cooperation of the first arc surface 65 and the second arc surface 66. The cooperation between the arc surfaces reduces the resistance that the shift block 61 needs to overcome during the rotation process, making the rotation of the shift block 61 smoother.

[0062] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
