[0018] A handle provided in an embodiment of the utility model includes a handle shell and a first handle piece. In actual use, the handle shell can be installed in a preset groove body of a door and window profile. Since the first side of the first handle piece is rotatably connected to the first receiving groove, the first handle piece can be rotated into the first receiving groove. When the first limiting portion of the first handle piece moves to the position of the second limiting portion provided on the side of the first receiving groove, the first limiting portion cooperates with the second limiting portion to limit, and at this time, the elastic force of the elastic member is not enough to make the first limiting portion disengage from the second limiting portion to make the first handle piece rotate and pop out, so the first handle piece will be fixed in the first receiving groove to achieve its hiding; when used When the user needs to use the handle, he can press down hard on the second side of the first handle piece.

DETAILED DESCRIPTION

[0033] The overall idea of ​​the technical solution provided by the utility model is as follows:

[0034] See also Figures 1 to 11 The handle includes: a handle housing 100, in which a first receiving groove 110 is provided; a first handle member 200, in which a first side of the first handle member 200 is rotatably connected to the first receiving groove 110; an elastic member 300, in which the elastic member 300 is connected between the first handle member 200 and the first receiving groove 110, and the elastic member 300 is used to provide elastic force to drive the second side of the first handle member 200 to rotate out of the first receiving groove 110; wherein, a first limiting portion 210 is provided on the side of the first handle member 200, and a second limiting portion 111 matching the first limiting portion 210 is provided on the side of the first receiving groove 110, and the first limiting portion 210 is used to elastically limit with the second limiting portion 111.

[0035] The utility model provides a technical solution for a handle, which is mainly composed of a handle housing 100, a first handle member 200 and an elastic member 300. In this configuration, a first receiving groove 110 is provided inside the handle housing 100 as a space for carrying and fixing the first handle member 200. The first handle member 200 is rotatably connected to one side in the first receiving groove 110 through its first side, forming a rotating connection design, which allows the first handle member 200 to be hidden in the first receiving groove 110 when not in use, thereby reducing space occupancy and improving overall aesthetics. The elastic member 300 is connected between the first handle member 200 and the first receiving groove 110, and is responsible for providing elastic force. When the user operates the first handle member 200, the elastic force of the elastic member 300 drives the second side of the first handle member 200 to rotate out of the first receiving groove 110, thereby realizing the rotation and ejection of the first handle member 200. In addition, a first limiting portion 210 is provided on the side of the first handle member 200, and correspondingly, a second limiting portion 111 matching the first limiting portion 210 is provided on the side of the first receiving groove 110. The first limiting portion 210 and the second limiting portion 111 cooperate to achieve elastic limiting.

[0036] In actual use, the handle housing 100 can be installed in a preset groove of the door and window profile. Since the first side of the first handle member 200 is rotatably connected to the first receiving groove 110, the first handle member 200 can be rotated into the first receiving groove 110. Figure 2As shown, when the first limiting portion 210 of the first handle member 200 moves to the position of the second limiting portion 111 provided on the side of the first receiving groove 110, the first limiting portion 210 cooperates with the second limiting portion 111 to limit, and at this time the elastic force of the elastic member 300 is not enough to make the first limiting portion 210 disengage from the second limiting portion 111 to make the first handle member 200 rotate and pop out, so the first handle member 200 will be fixed in the first receiving groove 110 to achieve its hiding; when the user needs to use the handle, he can press down the second side of the first handle member 200 with force, because the first limiting portion 210 is in the position of the second limiting portion 111, and the first limiting portion 210 is in the position of the second limiting portion 111. 10 and the second limiting portion 111 are elastically limited, so under the action of the downward pressure of the user, the first handle member 200 rotates toward the position in the first accommodating groove 110, and at the same time, the first limiting portion 210 will be separated from the second limiting portion 111, and the elastic member 300 will be heavily compressed. In this state, when the user lets go, the elastic force provided by the elastic member 300 will cause the second side of the first handle member 200 to rotate and pop out, and the elastic force provided by the elastic member 300 causes the first limiting portion 210 to be separated from the second limiting portion 111 when passing through the second limiting portion 111 to avoid mutual limitation of the two parties, such as Figure 3 As shown, at this time, the second side of the first handle member 200 will protrude outside the first receiving groove 110, and the user can grab it to operate the door and window. The utility model provides a handle for the user. Through the design of rotating and popping out, the handle can be hidden in the receiving groove when not in use, effectively saving space. It is particularly suitable for narrow environments or environments where doors and windows need to be prevented from opening outwards. When the user needs to use the handle, he only needs to press it lightly, and the elastic force of the elastic member 300 will drive the second side of the handle to rotate and pop out. The operation is simple and fast, which greatly improves the user experience. At the same time, the movement path of the first handle member 200 rotating and popping out is an arc. Compared with the straight path of translational pop-up, rotating pop-up can reduce the use of space, which is very useful in an environment with limited space.

[0037] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] See also Figure 1 and Figure 4, the first handle member 200 is rotatably connected to the first receiving groove 110 through the rotating shaft 400, wherein the first receiving groove 110 is provided with first shaft holes 112 on both sides, the first handle member 200 is provided with a plurality of second shaft holes 220, and the rotating shaft 400 is connected to the first shaft holes 112 and the second shaft holes 220. Specifically, the rotating shaft 400 is used to connect the first handle member 200 to the first receiving groove 110, and is connected at the first shaft hole 112 of the first receiving groove 110 and the second shaft hole 220 of the first handle member 200. Such a design allows the first handle member 200 to rotate in the first receiving groove 110 with the support of the rotating shaft 400.

[0039] See also Figure 1 and Figure 4 , a sleeve 113 is provided in the first shaft hole 112, and the rotating shaft 400 is connected to the sleeve 113. The setting of the sleeve 113 can reduce the direct friction between metals, and prevent the rotating shaft 400 from contacting the first shaft hole 112 to make a harsh noise when the first handle member 200 rotates, or prevent the smoothness of rotation from being affected due to excessive friction. This design not only ensures the smoothness of the operation of the handle member, but also greatly enhances the durability and stability of the handle.

[0040] See also Figure 1 , Figure 4 and Figure 6 The elastic member 300 is a torsion spring 310, the spiral portion 311 of the torsion spring 310 is connected to the rotating shaft 400, the first torsion arm 312 of the torsion spring 310 is connected to the first receiving groove 110, and the second torsion arm 313 of the torsion spring 310 is connected to the first handle member 200. The spiral portion 311 of the torsion spring 310 is connected to the rotating shaft 400, thereby realizing the connection between the spiral portion 311 and the rotating shaft 400. At the same time, the first torsion arm 312 of the torsion spring 310 is connected to the first receiving groove 110, so that when the first handle member 200 rotates, the first torsion arm 312 will be subject to resistance, causing the torsion spring 310 to be twisted, thereby storing energy. In addition, the second torsion arm 313 of the torsion spring 310 is connected to the first handle member 200, so that when the user releases the first handle member 200, the stored energy will drive the first handle member 200 to rotate back through the rebound of the second torsion arm 313.

[0041] See also Figure 1 and Figure 4 , a boss 114 is provided in the first receiving groove 110, and the boss 114 is located at the lower part of the rotating shaft 400. The boss 114 is used to limit the first handle member 200 when the first handle member 200 rotates to the position of the boss 114. Specifically, the boss 114 is a physical barrier, which prevents the first handle member 200 from rotating further, and can effectively limit the rotation range of the first handle member 200, ensuring that it stops rotating at a suitable position.

[0042] See also Figure 4 and Figure 6 , the boss 114 is provided with a first limiting hole 115 for fixing the first torsion arm 312, the first torsion arm 312 of the torsion spring 310 is connected to the first limiting hole 115, the first handle member 200 is provided with a second limiting hole 230, and the second torsion arm 313 is connected to the second limiting hole 230. Specifically, the boss 114 is provided with a first limiting hole 115, and the first limiting hole 115 is specially designed to fix the first torsion arm 312 of the torsion spring 310. During assembly, the first torsion arm 312 of the torsion spring 310 will be inserted and fixed in the first limiting hole 115. At the same time, the first handle member 200 is also designed with a second limiting hole 230. Similarly, the second torsion arm 313 of the torsion spring 310 will be connected to the second limiting hole 230. This setting ensures that when the torsion spring 310 is elastically deformed, the first torsion arm 312 and the second torsion arm 313 can be fixed in place, thereby giving full play to the elastic displacement performance of the torsion spring 310 and ensuring that it can reliably drive the first handle member 200 .

[0043] See also Figure 7 An anti-collision rubber 116 is provided on the boss 114. Specifically, when the first handle member 200 rotates and contacts the boss 114, the anti-collision rubber 116 can play a buffering role to prevent damage to components caused by hard contact or the user from feeling an impact during operation. The anti-collision rubber 116 can generally be produced using raw materials with high elasticity, wear resistance and pressure resistance, such as silicone and rubber.

[0044] See also Figure 1 , Figure 5 and Fig. 9 The first limiting portion 210 includes a limiting groove 211, the second limiting portion 111 includes a first spring member 117 and a ball member 118, and the side of the first accommodating groove 110 is provided with a first sliding groove 119 for accommodating the first spring member 117 and the ball member 118. The first side of the first spring member 117 is connected to the bottom of the first sliding groove 119, and the second side of the first spring member 117 is connected to the ball member 118. The ball member 118 is used to push against the limiting groove 211 under the elastic force of the first spring member 117. Specifically, when the first handle piece 200 rotates to enter the first receiving groove 110, the ball piece 118 moves toward the direction close to the limiting groove 211. When the ball piece 118 moves to the position of the limiting groove 211, it is driven by the elastic force of the first spring piece 117 and is pushed toward the limiting groove 211. The ball piece 118 is stabilized in the limiting groove 211 by the elastic force of the first spring piece 117. In this way, the first handle piece 200 is limited in the first receiving groove 110, thereby achieving stable hiding of the first handle piece 200 in the first receiving groove 110.

[0045] Furthermore, when the handle needs to be used, the user only needs to apply a certain thrust to the second side of the first handle piece 200 to make the first handle piece 200 rotate along the direction inside the first accommodating groove 110. At this time, the ball piece 118 will disengage from the limiting groove 211, and the user lets go. Since the torsion spring 310 is further compressed when the user applies a certain thrust to the second side of the first handle piece 200, the elastic energy storage increases. When the user stops applying the thrust, the elastic force of the torsion spring 310 quickly acts on the first handle piece 200, allowing it to pop out automatically. At the same time, the elastic force of the torsion spring 310 also ensures that the ball piece 118 can disengage from the limiting groove 211 when passing through the limiting groove 211, thereby avoiding mutual limitation between the ball piece 118 and the limiting groove 211.

[0046] More specifically, when the second side of the first handle member 200 is initially pushed into the first receiving groove 110, the ball member 118 moves toward the direction close to the limiting groove 211. When the ball member 118 moves to the position of the limiting groove 211, due to the elastic force applied to it by the first spring member 117, the ball member 118 will be elastically limited in the limiting groove 211. At this time, the torsion spring 310 will also apply an elastic force to the second side of the first handle member 200. However, at this time, the elastic force applied by the torsion spring 310 to the first handle member 200 is not enough to overcome the assistance of the ball member 118 in the limiting groove 211, so the ball member 118 118 will be limited in the limiting groove 211, and the first handle member 200 is hidden in the first receiving groove 110; when the user further applies a certain thrust to the second side of the first handle member 200, the torsion spring 310 is further compressed. When the user stops applying the thrust, the previously compressed torsion spring 310 will rebound quickly due to the elastic energy stored, and the elastic force provided will immediately act on the first handle member 200. At this time, when the ball member 118 passes through the limiting groove 211, the resistance encountered by the ball member 118 when moving in the limiting groove 211 is insufficient in front of the elastic force of the torsion spring 310. Therefore, the elastic force of the torsion spring 310 will push the ball member 118 to smoothly pass through the limiting groove 211 and break away from the mutual limiting state, thereby realizing the function of the ball member 118 breaking away from the limiting groove 211.

[0047] See also Figure 1 and Fig. 9The outer side of the handle housing 100 is provided with an elastic buckle assembly 500, which includes a buckle member 510 and a second spring member 520. The outer side of the handle housing 100 is provided with a second slide groove 120 for accommodating the buckle member 510 and the second spring member 520. The first side of the second spring member 520 is connected to the bottom of the second slide groove 120, and the second side of the second spring member 520 is connected to the buckle member 510. During installation, the user only needs to align the handle housing 100 and insert it into the preset groove of the profile, and the elastic buckle assembly 500 will automatically fasten the groove due to its own elastic characteristics. This not only ensures the stability of the handle housing 100, but also simplifies the installation process and improves the efficiency of installation. More specifically, the elastic buckle assembly 500 includes a buckle 510 and a second spring member 520. The outer side of the handle housing 100 is provided with a second slide groove 120 for accommodating the buckle 510 and the second spring member 520. The first side of the second spring member 520 is connected to the bottom of the second slide groove 120, and the second side of the second spring member 520 is connected to the buckle 510. Specifically, the preset groove is a groove. When the handle housing 100 is installed in the preset groove, the edge of the groove will apply pressure to the buckle 510, and this pressure will be transmitted to the second spring member 520 through the buckle 510, so that the second spring member 520 is compressed. At this time, the buckle 510 is equivalent to forming a "lever" between the edge of the groove and the second spring member 520, and the second spring member 520 is compressed to store energy. When the handle housing 100 is completely loaded and positioned in the groove, the pressure of the edge of the groove on the buckle 510 will be removed, the energy stored in the second spring member 520 will be released, and the second spring member 520 will try to return to its original state. In this process, the second spring member 520 releases energy and pushes the buckle 510 to move toward the inside of the groove body, so that the buckle 510 is stuck in the groove body, thereby fixing the handle housing 100 in the preset groove body.

[0048] See also Fig.10 and Fig.11The handle housing 100 is also provided with a second receiving groove 130 on one side of the first receiving groove 110, and a second handle member 600 is installed in the second receiving groove 130, and the second handle member 600 is rotatably connected to the second receiving groove 130, wherein a toggle portion 610 is provided on one side of the second handle member 600, and the toggle portion 610 passes through the handle housing 100 and is connected to the sliding member 700, and the toggle portion 610 is used to toggle the sliding member 700, and the sliding member 700 is used to connect the transmission structure of the door and window. Specifically, the second handle member 600 is rotatably connected to the second receiving groove 130, which means that the second handle member 600 can rotate around the rotation connection point with the second receiving groove 130, and then the second handle member 600 can rotate into the second receiving groove 130 and be hidden. For example, the second handle 600 and the second receiving groove 130 can be rotatably connected by a shaft, hinge or similar mechanism. When the second handle 600 rotates, the toggle portion 610 moves accordingly and toggles the sliding member 700. When the toggle portion 610 toggles the sliding member 700, the sliding member 700 moves, and then the sliding member 700 can drive the transmission structure of the door and window to realize the opening and closing action. Such a design makes the handle not only have the function of a handle, but also can realize the opening and closing function by driving the transmission structure of the door and window through the second handle 600, thereby improving the user experience.

[0049] See also Fig.10 The sliding member 700 is provided with a toggle groove 710, the toggle portion 610 is connected to the toggle groove 710, and one side of the sliding member 700 is connected to the handle housing 100 through a third spring member 720, and the third spring member 720 is used to return the sliding member 700 to its original position after being toggled. Specifically, when the toggle portion 610 toggles the sliding member 700, the third spring member 720 will be stretched or compressed; and when the force is removed, the third spring member 720 will use its own elastic force to push the sliding member 700 back to its original position. When the third spring member 720 returns the sliding member 700 to its original position, since the toggle portion 610 is connected to the toggle groove 710 of the sliding member 700, the movement of the sliding member 700 will drive the toggle portion 610, and then the second handle member 600 will also return to its original position. This setting ensures that no matter how the user operates the second handle member 600, the second handle member 600 can always return to its original position, thereby ensuring automatic resetting after operation, reducing the difficulty of use for the user, and improving the convenience of the product.

[0050] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept.
