[0023] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 2-Figure 8 :
[0024] Embodiment 1: An adaptive anti-collision door handle comprises a rocker arm 11 having a lock shaft mounting hole 10 or a lock shaft mounting groove at one end, the other end of the rocker arm 11 is hinged to one end of a connecting rod 19 through a first pin shaft 12, the other end of the connecting rod 19 is hinged to a handle through a second pin shaft 16, a first torsion spring 41 for driving the connecting rod 19 to rotate to one side is installed on the first pin shaft 12, and the other end of the rocker arm 11 and one end of the connecting rod 19 are provided with a limiting structure 23 for limiting the rotation angle of the connecting rod 19.
[0025] One end 22 of the first torsion spring 41 is limited on the slot 24 of the rocker arm 11 , and the other end 21 is limited on the slot 20 of the connecting rod 19 .
[0026] The limiting structure 23 for limiting the rotation angle of the connecting rod 19 can be a limiting block that cooperates with the connecting rod side wall to limit, or it can be a first limiting block 34 respectively arranged on the other end of the rocker arm 11 and a second limiting block 33 arranged at one end of the connecting rod 19.
[0027] When the first torsion spring 41 drives the connecting rod 19 to rotate around the first pin shaft 12 to a natural state where the first limit block 34 and the second limit block 33 cooperate to limit, the angle A between the rocker arm 11 and the connecting rod 19 is 100-180 degrees.
[0028] A middle gear 15 is installed in the middle part of the connecting rod 19 so as to rotate through the rotating shaft 14. A left gear 13 fixed relatively to the rocker arm 11 is provided on the first pin shaft 12, and a right gear 17 fixed relatively to the hand grip 18 is provided on the second pin shaft 16. The middle gear 15 is respectively meshed with the left gear 13 and the right gear 17 for transmission; the middle gear 15 is generally installed in the hollow cavity of the connecting rod 19 or in the cavity formed by the upper cover or the lower cover, and the left gear 13 and the right gear 17 are respectively extended into the grooves at one end or both ends of the connecting rod 19 and are respectively hinged to the connecting rod through the first and second pin shafts.
[0029] The left gear 13 is fixed or formed on the other end of the rocker arm 11 , and the right gear 17 is fixed or formed on one end of the connecting rod 19 .
[0030] The left gear 13 and the right gear 17 are both sector gears to meet the need of setting the rotation angle.
[0031] The above-mentioned connecting rod 19 is provided with a strip hole 51 arranged along the radial direction of the middle gear 15, and a third pin shaft 52 is slidably inserted into the strip hole 51, and a push handle 53 is provided on the third pin shaft 52 extending out of the connecting rod 19; after the third pin shaft 52 is pushed by the push handle 53 to move toward the center direction of the middle gear 15 to the inner end of the strip hole 51, the third pin shaft 52 is engaged in the tooth groove of the middle gear 15 to limit the rotation of the middle gear 15; after the third pin shaft 52 is pushed by the push handle 53 to move radially outward of the middle gear 15 to the outer end of the strip hole 51, the restriction of the third pin shaft 52 on the tooth groove of the middle gear 15 is released.
[0032] In this embodiment, three gears meshing with each other are used, so that the rotation of the connecting rod drives the handle to rotate synchronously, and during the rotation process, the handle and the rocker arm basically remain parallel to each other, and the handle can be rotated upward or downward at any time to unlock or lock.
[0033] When in use, it is necessary to position the lock shaft of the door and window lock on the lock shaft mounting hole 10 or the lock shaft mounting groove of the rocker arm 11; due to the elastic effect of the first torsion spring 41 and the limiting effect of the limiting structure, when the first torsion spring 41 is in a natural state after installation (no external force is applied to the hand handle and / or the connecting rod) and the rocker arm 11, the hand handle and the connecting rod are in the same straight line, the sudden closing of the glass door and window 02 or other doors and windows will not cause impact on the sliding mosquito-proof screen door and window 06 on the inside of the glass door and window 02 or other doors and windows, which can better protect the glass door and window 02 or other doors and windows or the sliding mosquito-proof screen door and window 06. Of course, in this case, when opening and closing the glass door and window 02 or other doors and windows, it is necessary to pull the hand handle outward first so that the hand can hold the hand handle, and turn the hand handle to open and close the glass door and window 02 or other doors and windows or aluminum alloy doors and windows; when the first torsion spring 41 is in the natural state after installation When the handle 11 is in the state (no external force is applied to the handle and / or the connecting rod) and the rocker arm 11 and the connecting rod have a certain angle A (greater than 100 degrees and less than 180 degrees), the glass door and window 02 or other doors and windows or aluminum alloy doors and windows are suddenly closed, and the handle and / or the connecting rod will collide with the sliding mosquito-proof screen door and window 06. Due to the elastic effect of the first torsion spring 41, the elastic force of the first torsion spring 41 can be overcome during the collision, and the handle can automatically translate toward the side of the door and window where the handle is installed to avoid collision and damage to the sliding mosquito-proof screen door and window or adjacently installed doors and windows, which can better protect the glass door and window 02 or other doors and windows or aluminum alloy doors and windows or the sliding mosquito-proof screen door and window 06 from damage and achieve an adaptive anti-collision effect. Of course, in this case, when opening and closing the glass door and window 02 or other doors and windows, the handle can be directly held by hand and the handle can be rotated to open and close the glass door and window 02 or other doors and windows or aluminum alloy doors and windows;
[0034] When the first torsion spring 41 is in a natural state after installation (no external force is applied to the hand grip and / or the connecting rod), the rocker arm 11 and the connecting rod have a certain angle A (greater than 100 degrees and less than 180 degrees), and the rocker arm 11 and the hand grip are parallel to each other, if the rocker arm 11, the hand grip and the connecting rod 19 are to be kept in the same straight line as normal, the hand grip should be pushed to be in the same straight line with the connecting rod 19 and the rocker arm 11, and then the push handle 53 should be used to push the third pin 52 to move toward the center of the middle gear 15 to the bar The inner end of the strip hole 51 makes the third pin shaft 52 engage in the tooth groove of the middle gear 15 to limit the rotation of the middle gear 15; when the door and window need to be opened and closed by the hand handle, the third pin shaft 52 should be pushed radially outward of the middle gear 15 to the outer end of the strip hole 51 through the push handle 53 to release the restriction of the third pin shaft 52 on the tooth groove of the middle gear 15, and the spring will automatically drive the hand handle to move outward, and then the hand handle is rotated to unlock or lock the door and window, as well as open and close the glass door and window 02 or other doors and windows or aluminum alloy doors and windows.
[0035] Embodiment 2: An adaptive anti-collision door handle comprises a rocker arm 11 having a lock shaft mounting hole 10 or a lock shaft mounting groove at one end, the other end of the rocker arm 11 being hinged to one end of a connecting rod 19 via a first pin shaft 12, the other end of the connecting rod 19 being hinged to a handle via a second pin shaft 16, a first torsion spring 41 for driving the connecting rod 19 to rotate to one side being installed on the first pin shaft 12, the other end of the rocker arm 11 and one end of the connecting rod 19 being provided with a limiting structure 23 for limiting the rotation angle of the connecting rod 19.
[0036] One end of the first torsion spring 41 is limited on the rocker arm 11 , and the other end is limited on the connecting rod 19 .
[0037] The limiting structure 23 for limiting the rotation angle of the connecting rod 19 can be a limiting block that cooperates with the connecting rod side wall to limit, or it can be a first limiting block 34 respectively arranged on the other end of the rocker arm 11 and a second limiting block 33 arranged at one end of the connecting rod 19.
[0038] When the first torsion spring 41 drives the connecting rod 19 to rotate around the first pin shaft 12 to a natural state where the first limit block 34 and the second limit block 33 cooperate to limit, the angle between the rocker arm 11 and the connecting rod 19 is 180 degrees or 20-50 degrees.
[0039] A second torsion spring 35 for driving the handle to rotate to one side is installed on the second pin shaft 16 , and a limiting protrusion 37 for limiting the rotation angle of the handle is provided on the other end of the connecting rod 19 and the handle 18 .
[0040] One end 36 of the second torsion spring 35 is limited on the connecting rod 19 , and the other end 38 of the second torsion spring 35 is limited on the hand grip 18 .
[0041] When the second torsion spring 35 drives the hand grip 18 to rotate relative to the connecting rod 19 until the limiting protrusion 37 is in a natural state of limiting, the angle C between the hand grip and the connecting rod 19 is 100-180 degrees.
[0042] The adaptive anti-collision principle of this embodiment is similar to that of embodiment 1. Only two torsion springs are used in conjunction with a limiting structure. When the first and second torsion springs are in a natural state after installation (no external force is applied to the hand grip and / or the connecting rod) and the rocker arm 11 and the connecting rod have a certain angle C (greater than 100 degrees and less than 180 degrees), the glass door and window 02 or other doors and windows are suddenly closed, and the hand grip and / or the connecting rod will collide with the sliding mosquito net door and window 06. Due to the elastic effect of the first torsion spring, the connecting rod will drive the hand grip to rotate along the first pin shaft 12 at the same time of the collision, thereby avoiding Avoid destructive impact on the sliding mosquito-proof screen door and window 06, can better protect the glass door and window 02 or other doors and windows or the sliding mosquito-proof screen door and window 06 from damage, and play an adaptive anti-collision effect. Of course, in this case, when opening and closing the glass door and window 02 or other doors and windows, you can directly hold and turn the handle to open and close the glass door and window 02 or other doors and windows; when the handle and the connecting rod have a certain angle of 180 degrees, suddenly opening and closing the doors and windows will not cause impact, but when opening and closing the doors and windows, you need to pull the handle outward first, and then turn the handle up and down to unlock or lock the doors and windows.
