Specific embodiments

[0025] The following combines the accompanying drawings with related embodiments to describe the implementation manners of the present utility model. The implementation manners of the present utility model are not limited to the following embodiments, and the relevant necessary components of the present utility model should be regarded as well-known technologies in the technical field, which can be known and mastered by those skilled in the technical field.

[0026] As Figure 1 shown, a multi-angle positioner for a flat door and window includes a fixed base 1, a movable base 2 and a base box 3. A connecting rod 4 is connected between the fixed base 1 and the movable base 2. Inside the base box 3, the movable base 2, the movable bar 5 and the transmission bar 6 are arranged in sequence from top to bottom. The two close contact surfaces of the movable base 2 and the movable bar 5 are both surfaces protruding towards each other along the locking direction, and the two close contact surfaces of the movable bar 5 and the transmission bar 6 are both provided with convex blocks protruding towards each other along the locking direction.

[0027] As Figures 1 to 8As shown in the figure, in the structure of the base box 3 of the present utility model, the base box 3 is a metal casting or an injection molding part with a hollow interior. At both ends of the base box 3 in the length direction, there are respectively a fixed plug 301 and a fixed plug 302. The fixed plug 301 and the fixed plug 302 are clamped at the ends of the base box 3 by an interference fit manner, thereby forming a transmission chamber 7 within the base box 3. At the top of the transmission chamber 7, there is a strip-shaped opening 701. The top of the movable base 2 extends upward along the strip-shaped opening 701 and is connected to the connecting rod 4;

[0028] It should be noted that during the opening and closing process of the door leaf, the base box 3 is in an unlocked state. In this state, the transmission bar 6 and the movable bar 5 are in a movable state. The convex block 601 on the transmission bar 6 and the convex block 502 on the movable bar 5 are in a staggered state, so that the movable base 2 in the transmission chamber 7 has a movable space for reciprocating movement along the length direction of the strip-shaped opening 701. The movable base 2 in the unlocked state can reciprocate along the length direction of the base box 3 in the transmission chamber 7 to a corresponding position according to different opening angles of the door leaf;

[0029] It should be noted that when the door leaf is in a fixed state, the base box 3 is in a locked state. When adjusted to the locked state, the transmission locking force is transferred to the transmission bar 6 by turning the handle. The transmission bar 6 moves along the length direction of the transmission chamber 7, so that the convex block 601 on the transmission bar 6 is aligned with the convex block 501 on the movable bar 5, causing the movable bar 5 to forcefully lift the movable base 2 upward, so that the movable base 2 in the transmission chamber 7 does not have a movable space for reciprocating movement along the length direction of the strip-shaped opening 701. By locking the movable base 2, the purpose of locking the opening angle of the door leaf is achieved. And the above positioning effect is determined by the positioning position of the user operating the handle to drive the transmission bar 6 at different opening angles of the door leaf. Therefore, as long as it is within the allowable use angle range of the structure of the present utility model, the door leaf can obtain the required fixed effect at multiple angles;

[0030] In the structure of the base box 3 of the utility model, there are respectively a fixed plug 301 and a fixed plug 302 at both ends of the base box 3, thereby forming a transmission chamber 7. Inside the transmission chamber 7, there are successively arranged from top to bottom a movable base 2, a movable bar 5 and a transmission bar 6. The movable base 2 is fixed between the movable bar 5 and the transmission bar 6 by a tensioning method. Among them, on the end face of the movable bar 5 facing the movable base 2, there is a wave-shaped protrusion 501, and on the end face of the movable base 2 facing the movable bar 5, there is a protrusion 201 matching the shape of the protrusion 501;

[0031] Further, the end surface of the movable bar 5 facing the transmission bar 6 is provided with a protrusion 1 502, the end surface of the transmission bar 6 facing the movable bar 5 is provided with a protrusion 2 601, the side of the protrusion 1 502 facing the protrusion 2 601 is provided with a slope 1 503, and the front end of the protrusion 2 601 corresponding to the locking direction is provided with a slope 2 602;

[0032] It should be noted that the two closely contacting surfaces of the movable base 2 and the movable bar 5 are both convex surfaces toward each other along the locking direction, and the shape of the protrusion 1 501 on the movable base 2 matches the shape of the protrusion 201 on the movable bar 5. When in an unlocked state, there is a margin of movement for the movable base 2 between the movable bar 5 and the top of the transmission chamber 7. When the angle of the door leaf changes, the movable base 2 moves along the length direction of the base box 3, that is, after the movable base 2 is subjected to force, there is a margin of movement between the protrusion 201 on the bottom end surface and the protrusion 1 501 on the top end surface of the movable bar 5, and no locking effect is played;

[0033] It should be noted that, in the state of transmission locking, the transmission bar 6 is moved in the locking direction by rotating the handle, so that the second protrusion 601 on the transmission bar 6 and the first protrusion 502 on the movable bar 5 are converted from the staggered state to the aligned state. When the transmission bar 6 moves in the locking direction, the second protrusion 601 and the first protrusion 502 are aligned with the inclined surface 602 and the inclined surface 503 through the inclined surface 603, thereby reducing the resistance of the handle transmission locking and avoiding the situation that the handle needs to be turned hard to lock.

[0034] It should be noted that, in the transmission locking state, the second protrusion 601 on the transmission bar 6 and the protrusion 1 502 on the movable bar 5 are aligned and in conflict with each other. When the protrusion 1 502 and the protrusion 2 601 are in the aligned and conflicting state, the movable bar 5 pushes upward, which has a tightening effect on the transmission chamber 7, and pushes the movable bar 5 to move upward to clamp and fix the movable base 2. In the locked state, the movable bar 5 and the top of the transmission chamber 7 clamp the movable base 2, and the protrusion 1 501 on the movable bar 5 and the protrusion 2 201 on the bottom end face of the movable base 2 are staggered and fitted, limiting the movement of the movable base 2, so that the movable base 2 cannot move in the locked state, thereby achieving the effect of fixing the opening angle of the door leaf.

[0035] Further, in the above solution, one end of the base box 3 is provided with a through hole one 303 penetrating along the thickness direction corresponding to the position of the first fixed plug 301, and the other end of the base box 3 is provided with a through hole two 304 penetrating along the thickness direction corresponding to the position of the second fixed plug 302. The through hole one 303 and the through hole two 304 are used to fix the base box 3 on the door leaf with screws. One end of the transmission bar 6 extends into the base box 3 along one end of the base box 3 corresponding to the second fixed plug 302, and the other end of the transmission bar 6 extends towards the outside of the base box 3 and is connected to a transmission source. A limiting groove 603 is provided at the position of the transmission bar 6 corresponding to the end of the base box 3. The limiting groove 603 is a strip-shaped notch, and the position of the limiting groove 603 corresponds to that of the through hole two 304. After the base box 3 is fixed at the top of the door leaf with screws, the screw passes through the through hole two 304 and simultaneously passes through the limiting groove 603, playing a role in restricting the transmission process of the transmission bar 6.

[0036] Further, in the above solution, the top of the movable base 2 is provided with an upward vertical opening one 202, and a rotating shaft one 203 is arranged in the opening one 202. One end of the connecting rod 4 is sleeved outside the rotating shaft one 203, and the fixed base 1 and the connecting rod 4 are hinged through the rotating shaft one 203. The bottom end of the fixed base 1 is provided with a downward vertical opening two 101, and a rotating shaft two 102 is arranged in the opening two 101. The other end of the connecting rod 4 is sleeved outside the rotating shaft two 102, and the movable base 2 and the connecting rod 4 are hinged through the rotating shaft two 102.

[0037] Further, in the above solution, the fixed base 1 is provided with a threaded through hole 103, and the threaded through hole 103 penetrates along the thickness direction of the fixed base 1 at an inclination angle. The fixed base 1 is fixed on the door frame by screwing a screw into the threaded through hole 103.

[0038] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
