DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] A small base window handle assembly, comprising a rotating handle 1, an outer cover 2, a connector 3, a square rod 4, a base 5 and a holder 6, wherein the holder 6 is fixedly arranged at the center of one side of the base 5, and the size of the holder 6 is smaller than the size of the base 5. The aluminum alloy profile 32 of the window is usually hollow, and a mounting hole is provided at the position where the window handle is installed. The size of the holder 6 in the present invention matches the size of the mounting hole of the profile 32. During installation, the holder 6 is inserted into the mounting hole. Since the size of the base 5 is larger than the size of the holder 6 and the mounting hole, the base 5 is attached to the surface of the profile 32. A second mounting hole 13 is provided through the center of the base 5, and a second mounting hole 13 is provided through the center of the holder 6 to connect with the second mounting hole. 13 corresponding to and connected to the third mounting hole 14, the side wall of the card seat 6 extends inward to form at least two mounting grooves 7, the mounting groove 7 is matched with a pressing block 8, the pressing block 8 is movably arranged in the mounting groove 7, and in the initial state, the pressing block 8 is completely hidden in the mounting groove 7, one end of the pressing block 8 is provided with a first threaded hole 9, and the end of the pressing block 8 with the first threaded hole 9 is arranged close to the inner wall of the corresponding mounting groove 7, the first threaded hole 9 is correspondingly provided with a first through hole 11, the first through hole 11 extends from the surface of the base 5 away from the card seat 6 side toward the first threaded hole 9 and is connected, the first through hole 11 is provided with a bolt 12 matching the first threaded hole 9, the bolt 12 is provided from the base 5 away from the card seat 6 side The first through hole 11 is passed through from the side of the holder 6 and is screwed to the first threaded hole 9. By selecting the material of the pressing block 8, the connection between the bolt 12 and the pressing block 8 is not easy to loosen after long-term use. Before installation, the bolt 12 is preliminarily connected to the first threaded hole 9, but not locked. The pressing block 8 is completely hidden in the installation groove 7. The size of the pressing block 8 is smaller than the size of the installation groove 7. After the pressing block 8 is connected to the bolt 12, the pressing block 8 is suspended in the installation groove 7. The pressing block 8 has no contact with the inner wall of the installation groove 7. During installation, the profile 32 is placed horizontally with the mounting hole facing upward, and then the holder 6 is inserted into the mounting hole so that the mounting groove 7 and the pressing block 8 are located inside the profile 32 and rotated in the direction of the bolt 12 to tighten. Bolt 12, since the pressing block 8 is suspended in the air, the pressing block 8 will first rotate with the bolt 12, and the end of the pressing block 8 away from the first threaded hole 9 will rotate toward the outside of the installation groove 7 with the bolt 12 as the rotation axis. Since the pressing block 8 has an end of the first threaded hole 9 close to the inner wall of the installation groove 7, when the pressing block 8 rotates to contact the inner wall, it will not rotate further due to the resistance of the inner wall. Continue to rotate the bolt 12, and the pressing block 8 will move along the thread of the bolt 12 toward the direction of the base 5 until it contacts the inner wall of the profile 32. The base 5 is attached to the surface of the profile 32, and the pressing block 8 is attached to the inner wall corresponding to the surface in the profile 32. After the bolt 12 is tightened, the profile 32 is clamped by the pressing block 8 and the base 5 to fix it.

[0022] The outer cover 2 is covered on the base 5 by a side of the base 5 away from the card seat 6, and the side wall of the outer cover 2 wraps the side wall of the base 5. The outer cover 2 is detachably connected to the base 5. The center of the outer cover has a first mounting hole 17 corresponding to and connected to the second mounting hole 13. The first mounting hole 17, the second mounting hole 13 and the third mounting hole 14 are penetrated by a connector 3. The part of the connector 3 corresponding to the second mounting hole 13 and / or the third mounting hole 14 has a rotating part 23 matching the second mounting hole 13 and / or the third mounting hole 14. The rotating part 23 is rotatably connected in the second mounting hole 13 and / or the third mounting hole 14. In the present invention, the second mounting hole 13 and the third mounting hole 14 are connected to the outer cover 2. The mounting holes 14 are all circular, and the rotating part 23 is a matching cylindrical shape. A first connecting hole 19 is provided in the connecting head 3 along the length of the connecting head 3. The rotating handle 1 is located on the side of the outer cover 2 away from the base 5. One end of the rotating handle 1 has a socket 31 matching the connecting head 3. The connecting head 3 is inserted into the socket 31. The end of the connecting head 3 away from the rotating handle 1 is matched with a square rod 4, and the square rod 4 is inserted into the first connecting hole 19. The square rod 4 is connected to the locking system of the window. This is the prior art. The rotating handle 1, the connecting head 3 and the square rod 4 are fixed by a fixing structure. The rotating handle 1 is rotated to drive the square rod 4 to rotate through the connecting head 3, thereby driving the locking system.

[0023] According to a preferred technical solution, a first tooth pattern 10 is protruded on a surface of the pressing block 8 facing the base 5, and a second tooth pattern 30 corresponding to the first tooth pattern 10 is protruded on a side of the base 5 facing the pressing block 8. The friction force in contact with the profile 32 is increased by the first tooth pattern 10 and the second tooth pattern 30, so that the pressing block 8 and the base 5 can clamp the profile 32 more firmly and are not easy to loosen.

[0024] A preferred technical solution is that at least two limiting protrusions are evenly distributed on the side wall of the socket 6 along the circumference of the socket 6, the limiting protrusions protrude from the side wall of the socket 6, and the edge of the mounting hole of the profile 32 has a limiting groove matching the limiting protrusions. When the socket is inserted into the mounting hole, the limiting protrusion is inserted into the limiting groove, so that the socket 6 is not easy to rotate after being inserted into the mounting hole, making the installation more stable.

[0025] A preferred technical solution is that the outer cover 2 is detachably connected to the base 5 through a snap-fit ​​structure, and the snap-fit ​​structure includes a snap edge 15 protruding from the base 5 toward the outer cover 2, and the snap edges 15 are distributed around the second mounting hole 13, and the snap edge 15 extends outward from one side of the outer cover 2 to form a snap edge 16, and a card 18 corresponding to the snap edge 15 is provided in the first mounting hole 17 of the outer cover 2, and the card 18 extends inward from the side wall of the first mounting hole 17, and the thickness of the card 18 matches the distance between the snap edge 16 and the base 5. In the connected state, the inner edge of the card 18 is snapped between the snap edge 16 and the base 5 for fixation.

[0026] According to a preferred technical solution, a plurality of auxiliary protrusions are protruding from the side wall of the base 5, and the auxiliary protrusions abut against the inner wall of the outer cover 2. After the outer cover 2 is covered on the base 5, the auxiliary protrusions abut against the inner wall of the outer cover 2, so that the outer cover 2 is more firmly covered on the base 5.

[0027] The preferred technical solution is that a gear assembly is provided on one side of the card seat 6 away from the base 5. The existing window has more than one opening method. It can be opened and closed by rotating with the vertical side as the axis, and can also be opened and closed by rotating with the horizontal side as the axis. The rotating handle 1 is rotated to different gear positions to drive different locking systems and perform different switching methods. The above is the prior art. The gear assembly includes two gear slots 28 arranged on the card seat 6. The two gear slots 28 are symmetrically arranged on both sides of the third mounting hole 14. A spring 26 is arranged in the gear slot 28. The length of the spring 26 is set along the depth of the gear slot 28. The spring 26 is away from the gear slot 28. One end of the notch is fixedly connected to the gear slot 28, and the other end of the spring 26 is fixedly provided with a gear ball 27. The end of the connector 3 corresponding to the holder 6 is fixedly provided with a gear seat 24, and the gear seat 24 is located on the side of the holder 6 away from the base 5. The gear seat 24 has a second connecting hole 29 connected to the first connecting hole 19, so that the square rod 4 can pass through the gear seat 24. The gear seat 24 has four circular holes 25 corresponding to the gear ball 27, and the four circular holes 25 are equidistantly distributed around the second connecting hole 29. The diameter of the circular hole 25 is smaller than the diameter of the gear ball 27. In the initial state, the gear ball 27 extends out of the gear slot 28 and is inserted into the circular hole 25.

[0028] The base 5 and the card seat 6 are fixed on the profile 32 of the window, and the gear seat 24 rotates with the connecting head 3. Therefore, when the rotating handle 1 is rotated, the gear seat 24 rotates to squeeze the gear ball 27 toward the gear slot 28. When the rotating handle 1 is rotated 90°, the two round holes 25 on the gear seat 24 rotate to the position of the two gear balls 27. Therefore, the two gear balls 27 will be stuck in the round holes 25 due to the elastic force, fixing the rotation of the rotating handle 1. When it is necessary to change the gear again, the rotating handle 1 is rotated forcefully, and the gear seat 24 squeezes the gear ball 27 toward the gear slot 28 again.

[0029] According to a preferred technical solution, there are three mounting grooves 7, and the three mounting grooves 7 are spaced apart at an angle of 90° between each other. The positions of the three mounting grooves 7 correspond to the positions of the gears of the rotating handle 1. Normally, the rotating handle 1 has three gears. Turning the handle 1 upward closes the window, rotating the handle 1 90° toward one side is a way of moving and opening the window, and continuing to rotate the handle 1 90° toward the downward side is another way of opening. When the window is pushed and pulled in three different positions, there are different stress points on the base 5, and the three mounting grooves 7 correspond to different stress points. After the pressure blocks 8 in the three mounting grooves 7 clamp the profile 32 with the base 5, the structural strength of the three stress points is enhanced.

[0030] A preferred technical solution, the fixing structure includes a second threaded hole 20 provided on the rotating handle 1, the second threaded hole 20 is connected to the insertion hole 31, the connecting head 3 has a second through hole 22 corresponding to the second threaded hole 20, the second through hole 22 is connected to the second threaded hole 20, a screw 21 is provided in the second threaded hole 20, the inner end of the screw 21 passes through the second through hole 22 and abuts against the surface of the square rod 4 for locking and fixing.
