[0036] Example 1:

[0037] See also Figures 1-3 The present invention provides a door and window handle structure, including: two handles 1, a fixing base 2, a shaft component 3, a toggle member 4 and a locking member 5, one end of the shaft component 3 is connected to one of the handles 1, and the other end of the shaft component 3 passes through the fixing base 2 and is connected to the other handle 1, one end of the toggle member 4 is arranged in one of the handles 1, and the other end of the toggle member 4 passes through the fixing base 2 and is arranged in the other handle 1, the toggle member 4 can rotate relative to the two handles 1, an accommodating portion 6 is provided on the fixing base 2, and the locking member 5 is retractably arranged in the accommodating portion 6, and the toggle member 4 is arranged corresponding to the locking member 5. When the toggle member 4 rotates relative to the two handles 1, the toggle member 4 can drive the locking member 5 to disengage or get stuck in the handle 1, thereby unlocking or locking the handle 1.

[0038] This embodiment realizes the functions of indoor locking and outdoor unlocking only through the shaft component 3, the toggle component 4, the fixing seat 2 and the locking component 5. It has a simple structure and does not require other additional accessories, thereby improving the assembly efficiency and reducing the cost. At the same time, the handle 1 can be used both inside and outside without distinguishing between left and right, and has strong versatility.

[0039] Specifically, the fixing seat 2 is provided with a through hole 7 connected to the accommodating portion 6, and the handle 1 is provided with a protrusion 8, which is installed in the through hole 7. The protrusion 8 is provided with a locking portion 9. One end of the locking member 5 is inserted into the locking portion 9 and abuts against the toggle member 4. When the toggle member 4 rotates relative to the two handles 1, the toggle member 4 pushes one end of the locking member 5 out of the locking portion 9.

[0040] Furthermore, the shape of the protrusion 8 is similar to that of the through hole 7. The protrusion 8 adopts a shape similar to that of the through hole 7 so that the handle 1 will not shake during rotation, thereby reducing damage to the handle 1 and the fixing base 2 caused by shaking, increasing the service life of the handle 1 and the fixing base 2, and reducing replacement costs.

[0041] Furthermore, in order to reduce the wear of the handle 1 and the fixing seat 2 during the rotation process, the present embodiment further provides a washer 10 (such as Figure 1 As shown), the washer 10 is sleeved on the protrusion 8 and embedded in the through hole 7.

[0042] The working principle of the door and window handle 1 structure is as follows: Figure 4 As shown, when the handle 1 needs to be locked, the toggle member 4 is rotated to reduce the driving radius of the contact point between the toggle member 4 and the locking member 5, so that the locking member 5 is inserted into the locking portion 9. At this time, the locking member 5 is located between the accommodating portion 6 and the locking portion 9, and the fixing base 2 is fixed, so the handle 1 is also relatively fixed; Figure 5As shown, when the handle 1 needs to be unlocked, the rotating knob 4 makes the driving radius of the contact point between the knob 4 and the locking member 5 larger, so that the locking member 5 is separated from the locking part 9, at this time the locking member 5 is located in the accommodating part 6, so the handle 1 can be rotated freely.

[0043] It should be noted that in the embodiment, the knob 4 can be arranged in the shaft member 3 or outside the shaft member 3. For the knob 4 arranged in the shaft member 3, the side of the shaft member 3 close to the locking member 5 is arranged in an open type, that is, the side of the shaft member 3 close to the locking member 5 is provided with an open slot, when the knob 4 rotates, the surface of the shaft member 3 can be exposed to push the locking member 5 to separate from the locking part 9 on the handle 1, so as to realize the unlocking of the handle 1. For the knob 4 arranged outside the shaft member 3, an installation slot (not shown in the figure) for installing the knob 4 can be arranged on the handle 1, and the installation slot is communicated with the locking part 9, so that the locking member 5 can abut against the knob 4 through the locking part 9, at this time, the handle 1 can be unlocked by only rotating the knob 4 to separate the locking member 5 from the locking part 9.

[0044] In order to realize the close abutment between the locking member 5 and the knob 4, please refer to Figure 1 The embodiment further comprises a reset member 11 arranged in the accommodating part 6, one end of the reset member 11 abuts against the fixed seat 2, and the other end of the reset member 11 abuts against the locking member 5. The reset member 11 makes the locking member 5 abut against the knob 4 closely at any position, and provides a reset force to the locking member 5 along the moving direction of the locking member 5. For example, when the accommodating part 6 is arranged below the shaft member 3, the locking member 5 is always located in the accommodating part 6 under the action of its own gravity, and cannot be moved into the locking part 9 to abut against the knob 4. At this time, the locking member 5 cannot lock the handle 1, but when the reset member 11 is arranged, under the elastic force of the reset member 11, the locking member 5 can abut against the knob 4 closely by overcoming its own gravity.

[0045] The reset member 11 is generally a spring, and can also be a rubber ball.

[0046] Please refer to Figure 3 In the embodiment, the handle 1 is provided with an accommodating hole 12, and the two ends of the shaft member 3 are respectively inserted into the accommodating holes 12 of the two handles 1, and the shapes of the two ends of the shaft member 3 are similar to the shapes of the accommodating holes 12. When the shaft member 3 is inserted into the two handles 1, the shaft member 3 and the two handles 1 are preliminarily fixed. However, the connection mode that the shaft member 3 and the handle 1 are directly inserted and matched to realize the preliminary fixation has some problems, for example, there is a large gap between the shaft member 3 and the handle 1, which causes the handle 1 to shake and the operation experience to be poor. In order to realize the stable connection between the shaft member 3 and the handle 1, the handle 1 of the embodiment is provided with a threaded hole 13 (as shown in the figure) at a position perpendicular to the accommodating hole 12. Figure 3As shown), when the shaft is mounted on the handle 1, a screw member 14 (as shown) is used to Figure 1 As shown in the figure, the handle 1 is screwed into the threaded hole 13 and is in close contact with the shaft component 3 to achieve a stable connection between the shaft component 3 and the handle 1, thereby improving the user's operating experience. At the same time, the tight connection can also reduce the risk of wear and damage, and increase the overall service life of the handle 1.

[0047] See also Figure 1 In order to more conveniently rotate the toggle member 4 , a driving member 15 is provided on the handle 1 of this embodiment, and the driving member 15 is connected to the toggle member 4 .

[0048] For details, please refer to Figure 6 and Figure 7 The handle 1 is provided with a mounting hole 16 connected to the accommodating hole 12 , and one end of the driving member 15 is provided with a buckle 17 . One end of the driving member 15 is inserted into the mounting hole 16 and is clamped to the accommodating hole 12 through the buckle 17 .

[0049] More specifically, the handle 1 is provided with a mounting hole 16 that is connected to the accommodating hole 12, and a buckle 17 is provided at one end of the driving member 15. One end of the driving member 15 is inserted into the mounting hole 16, and the diameter of the mounting hole 16 is smaller than the diameter of the accommodating hole 12, so that the accommodating hole 12 and the mounting hole 16 are connected to form a stepped through hole. When the driving member 15 is inserted into the mounting hole 16, the buckle 17 and the accommodating hole 12 are assembled and limited, that is, the connecting end surface between the accommodating hole 12 and the mounting hole 16 is limited by the buckle 17.

[0050] In order to realize the positioning of the driving member 15, the driving member 15 of this embodiment is provided with a plurality of positioning holes 18 (such as Figure 6 As shown), an elastic positioning component 19 is provided in the handle 1 (as Figure 1 As shown) and one end of the elastic positioning component 19 is exposed on the surface; or, a plurality of positioning holes 18 are provided in a ring on the handle 1, and an elastic positioning component 19 is provided in the driving member 15 and one end of the elastic positioning component 19 is exposed on the surface; when the driving member 15 rotates, the exposed end of the elastic positioning component 19 cooperates with the plurality of positioning holes 18 for positioning, wherein the elastic positioning component 19 can adopt a spring and ball structure design, and can also adopt a spring and roller structure design.

[0051] Usually, the indoor and outdoor driving members 15 need to be distinguished. In order to protect the property and life safety of the user, the outdoor driving member 15 needs to consider anti-theft and safety to prevent outsiders from easily unlocking it, while the indoor rotation does not need to consider anti-theft and safety. Therefore, the indoor driving member 15 only needs to consider the convenience of operation. In this embodiment, the driving member 15 is an inner knob with a raised outer side (such as Figure 7 As shown), or the driving member 15 is an outer knob with a groove on the outside (as shown Figure 8The driving member is a lock cylinder (not shown in the figure), the inner knob is installed indoors, and the outer knob is installed indoors.

[0052] To achieve the convenience of the inner knob operation, the embodiment is provided with a boosting part 20 (as shown in Figure 7 The boosting part 20 is usually designed as a protrusion, and further, to be beautiful, the boosting part 20 is usually small, so the user's finger often slips off the boosting part 20 during use. To avoid slipping, the boosting part 20 is provided with anti-skid lines, and the surface of the boosting part 20 can also be made of anti-skid materials or embedded in the boosting part 20, such as rubber, plastic and the like.

[0053] Since the outdoor driving member 15 needs to consider the anti-theft and safety, the outer knob usually does not have a corresponding operation device, but it cannot deal with some special situations, for example, a child accidentally locks himself indoors, and he does not know how to unlock the handle 1. In such a situation, a device that can be unlocked from indoors should be provided. In the embodiment, the outer knob is provided with an emergency slot 21 (as shown in Figure 8 for unlocking the handle 1 in an emergency.

[0054] When the driving member 15 is a lock cylinder, the handle can only be unlocked or locked by a specific key, further increasing the safety of the door and window lock and reducing the possibility of the door and window handle being pried open.

[0055] The structure of the locking member 5 will be described below:

[0056] Please refer to Figure 9 The locking member 5 includes locking surfaces 22 arranged on both sides of the locking member 5 and a driving surface 23 arranged on the locking member 5 close to one end of the actuator 4. The two locking surfaces 22 are connected with the driving surface 23, wherein the driving surface 23 is used to drive the locking member 5 to slide and unlock, and the locking surface 22 is used to be clamped into the handle 1, thereby achieving the locking of the handle 1.

[0057] Further, when the reset member 11 is a spring, the locking member 5 is provided with a guide column 24 close to one end of the actuator 4, and the reset member 11 is sleeved on the guide column 24. The design of the guide column 24 makes the reset member 11 not displace during the compression process, thereby damaging the reset member 11. In other words, the reset member 11 will be subjected to a radial force during the compression process, and under the radial force, the two ends of the reset member 11 will move. If the moving directions of the two ends are different, the reset member 11 will be deformed along the radial direction, and the radial deformation usually cannot automatically recover, so it will damage the reset member 11. The design of the guide column 24 prolongs the service life of the reset member 11 and reduces the damage rate and replacement cost of the reset member 11.

[0058] In order to facilitate the pushing of the reset member 11, the locking member 5 of the embodiment is arc-shaped at one end abutting the toggle member 4, that is, the driving surface 23 is arc-shaped. The arc-shaped driving surface 23 enables the toggle member 4 to more smoothly and conveniently push the reset member 11.

[0059] Embodiment 2:

[0060] Referring to Figure 10 , the embodiment includes two handles 1, a fixed seat 2, a shaft component 3, a toggle member 4, and a locking member 5. One end of the shaft component 3 is connected to one of the handles 1, and the other end of the shaft component 3 passes through the fixed seat 2 and is connected to the other handle 1. One end of the toggle member 4 is arranged in one of the handles 1, and the other end of the toggle member 4 passes through the fixed seat 2 and is arranged in the other handle 1. The toggle member 4 can rotate relative to the two handles 1. The fixed seat 2 is provided with a receiving portion 6, and the locking member 5 is arranged in the receiving portion 6. The toggle member 4 is arranged corresponding to the locking member 5. When the toggle member 4 rotates relative to the two handles 1, the toggle member 4 can drive the locking member 5 to disengage or be clamped into the shaft component 3, thereby achieving unlocking or locking of the handle 1.

[0061] Specifically, referring to Figure 11 , the shaft component 3 is provided with a receiving portion 25 along the axial direction, and the toggle member 4 is arranged in the receiving portion 25. One end of the locking member 5 is inserted into the receiving portion 25 and abuts on the toggle member 4. When the toggle member 4 rotates relative to the two handles 1, the toggle member 4 pushes one end of the locking member 5 out of the receiving portion 25.

[0062] The working principle of the door and window handle 1 is as follows: Figure 12 When it is necessary to lock the handle 1, the toggle member 4 is rotated so that the driving radius of the contact point between the toggle member 4 and the locking member 5 becomes smaller, thereby causing the locking member 5 to be inserted into the receiving portion 25. At this time, the locking member 5 is located between the receiving portion 6 and the receiving portion 25, and the fixed seat 2 is fixed and does not move. Therefore, the shaft component 3 is also fixed and does not move, and the two handles 1 connected to the shaft component 3 are also fixed and do not move. Figure 13 When it is necessary to unlock the handle 1, the toggle member 4 is rotated so that the driving radius of the contact point between the toggle member 4 and the locking member 5 becomes larger, thereby causing the locking member 5 to disengage from the receiving portion 25. At this time, the locking member 5 is located in the receiving portion 6, and therefore the handle 1 can be rotated at will.

[0063] In the embodiment, the locking of the two handles 1 is achieved by the locking of the fixed seat 2 and the shaft component 3. Therefore, the handle 1 is not provided with a protrusion 8. In order to solve the problem of shaking of the handle 1 during rotation, the outer periphery of the shaft component 3 is provided with an annular protrusion 26 (as shown in Figure 11The annular protrusion 26 is matched with the through hole 7 on the fixing base 2, and the matching of the annular protrusion 26 and the through hole 7 on the fixing base 2 solves the shaking problem of the handle 1 during rotation. Meanwhile, the annular protrusion 26 can also be used to drive the driving surface 23 of the locking member 5 to move and unlock the locking member 5. Further, the fixing base 2 is provided with a washer 10 installed in the through hole 7, the shaft component 3 penetrates the washer 10, the annular protrusion 26 is limitedly matched with the inner ring of the washer 10, the limited matching of the annular protrusion 26 and the inner ring of the washer 10 solves the shaking problem of the handle 1, and the setting of the washer 10 reduces the abrasion between the fixing base 2 and the shaft component 3.

[0064] It can be understood that different structural designs in the above embodiments can be combined for use, for example, the protrusion 8 on the handle 1 in Embodiment 1 is combined with the annular protrusion 26 on the shaft component 3 in Embodiment 2, which can make the rotation of the handle 1 more stable and improve the operation experience of the user, and other combined use modes are not described here.

[0065] The embodiments in the description are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same and similar parts between the embodiments can be referred to each other.
