Description

Technical Field

[0001] The invention relates to the technical field of window openers, and more particularly to a hand-operated window opener with a self-locking function. Background Art

[0002] A hand-cranked window opener is a manual mechanical device used to open and close windows. Its main function is to convert manpower into power that can push the window to open or close through manual operation, so that the window can be opened and closed conveniently and safely. It is especially suitable for some larger, heavier or higher-positioned windows.

[0003] The existing hand-cranked window opener usually only needs to simply shake the corresponding operating parts, such as the hand crank, rocker, etc., to open and close the window. However, for some heavier windows, the existing hand-cranked window opener requires a large force when opening and closing, and for some people with less strength, such as children, the elderly or people with weak bodies, it may be difficult to independently complete the window opening and closing operation; and the speed of the hand-cranked window opener depends entirely on the speed of the user's hand cranking. In some situations where emergency ventilation or rapid window closing is required to cope with bad weather, such as when a rainstorm is approaching and the window needs to be closed quickly, the speed of the existing hand-cranked window opener may not meet the requirements, resulting in low practicality and flexibility of the existing hand-cranked window opener.

[0015] A method for using a hand-operated window opener with a self-locking function comprises the following steps:

[0016] S1, transmission mode switching operation, by pushing the rocking handle 3 upward to drive the toothed plate to rotate, the toothed plate drives the second rotating ring plate to rotate through the outer tooth opening 3, further making the first rotating ring plate rotate around the inner side wall of the circular groove, the arc groove on the side wall of the second rotating ring plate drives the slide plate to slide in the slide groove through the plug column, so that the slide plate leaves the slot, at this time, the slide plate loses the restricting effect on the locking ring plate, so that the locking ring plate can rotate freely, and further making the base can rotate around the inner side wall of the second chamber through the rotating column 1 and the rotating column 2;

[0017] S1.1. When the crank handle 1 is held and pulled downward, the base rotates 90 degrees downward in the horizontal direction, so that the first rotating column remains in a vertical state, the gear 1 is separated from the inner tooth of the rack, and the second rotating column and the third rotating column remain in a horizontal state, the gear 3 is meshed with the outer tooth 1 of the rack, and the force arm of the outer tooth 1 of the rack becomes longer relative to the inner tooth. According to the principle of lever, the rack can be driven to rotate with a smaller force. At this time, the rotation adjustment component is in a labor-saving mode;

[0018] S1.2, when holding the crank handle 1 and pushing it upward, the base rotates 90 degrees upward in the horizontal direction, so that the first rotating column remains horizontal, the gear 1 is in meshing with the inner tooth opening of the rack, and the second rotating column and the third rotating column remain vertical, the gear 3 is separated from the outer tooth opening 1 of the rack, and the inner tooth opening of the rack becomes shorter than the outer tooth opening. When the gear 1 rotates, the rack speed increases. At this time, the rotation adjustment component is in acceleration mode;

[0019] S2. If the hand-operated window opener is used in a case where the user has less strength, the rotation adjustment component is adjusted to the labor-saving mode, and then the user holds the second grip tube with one hand and rotates the crank handle 2 with the other hand, so that the crank handle 2 drives the second rotating column, gear 2 and gear 3 to rotate, and the gear 3 easily drives the ring frame to rotate through the outer tooth opening 1, and the ring frame drives the second worm wheel, the transmission rod and the first worm wheel to rotate through the second worm, and the first worm drives the rotating rod to rotate through the first worm wheel, and the rotating rod drives the first push rod and the second push rod to perform the window opening action or the window closing action;

[0020] S3. If the hand-operated window opener is used in bad weather and the window needs to be closed quickly, the rotating adjustment component is adjusted to the acceleration mode, and then the user holds the first grip tube with one hand and rotates the crank handle 1 with the other hand. The crank handle 1 drives the first rotating column and gear 1 to rotate, and the gear 1 drives the ring frame to rotate quickly through the inner teeth, further allowing the first push rod and the second push rod to quickly close the window.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention is designed with a rotation adjustment component having a labor-saving mode and an acceleration mode; in the labor-saving mode, the transmission rod can be easily driven to rotate, so that heavier windows can be easily opened, and it is convenient for users to use it when they have less strength; in the acceleration mode, the rotation speed of the transmission rod can be accelerated, so that the window can be quickly opened or closed, which solves the need for use in some situations where emergency ventilation or quick closing of windows to cope with bad weather is required. The practicality and flexibility of the device are improved by freely switching the dual modes of the rotation adjustment component.

[0023] 2. The present invention arranges inner teeth on the inner circumferential wall of the ring wheel and outer teeth one on the outer circumferential wall. Through the circumference difference and lever arm difference between the inner teeth and the outer teeth one, when gear one transmits the ring wheel through the inner teeth, the circumference and lever arm of the inner teeth are shorter. Although more force is required, the rotation speed of the ring wheel can be accelerated, and the function of quickly opening or closing the window can be further achieved. The outer teeth one has a longer lever arm than the inner teeth. According to the lever principle, gear three only needs a smaller force to drive the ring wheel to rotate through the outer teeth one. The purpose of switching the two transmission modes of the rotation adjustment component can be achieved by simply switching the meshing of gear one with the inner teeth or the meshing of gear three with the outer teeth one, thereby making the device simple and quick to operate, and more practical and flexible.

[0024] 3. The present invention also drives the toothed plate to rotate by pushing the shaking handle three upwards, and the toothed plate drives the second rotating circle plate to rotate through the outer tooth opening three, further making the first rotating circle plate rotate around the inner wall of the circular groove, and the arc groove on the side wall of the second rotating circle plate drives the slide plate to slide in the slide groove through the plug column, so that the slide plate leaves the slot. At this time, the slide plate loses its restricting effect on the locking ring plate, so that the locking ring plate can rotate freely, and further makes the base able to rotate around the inner wall of the second chamber through the rotating column one and the rotating column two. Through the rotation of the base, it is guaranteed that the rotation adjustment component can stably switch between the labor-saving mode and the acceleration mode. When the rotation adjustment component remains in the labor-saving mode or the acceleration mode, it only needs to insert the slide plate into the slot so that the slide plate forms a restricting rotation effect on the locking ring plate, further making the base remain in a fixed state and difficult to rotate, thereby improving the stability of the device working in the labor-saving mode or the acceleration mode.

[0025] 4. In the present invention, when the rocking handle 3 is pushed upward to drive the toothed plate to rotate, the block on the circumferential side wall of the rotating plate slides along the arc column and cooperates with the lower baffle plate to compress the spring until the slide plate leaves the slot and rotates the base to achieve the purpose of switching the rotation adjustment component to the effort-saving mode or the acceleration mode. During the switching process, the base can drive the locking ring plate to rotate so that the slot of the locking ring plate is misaligned with the slide plate. At this time, the rocking handle 3 can be released, and the block is subjected to the elastic force of the compressed spring and slides back along the arc column, further driving the rotating plate to rotate back, and cooperates with the gravity of the rocking handle 3 itself to make the toothed plate automatically rotate, further driving the slide plate to slide toward the circumferential outer wall of the locking ring plate, until the rotation adjustment component is switched to the effort-saving mode or the acceleration mode, the base drives the locking ring plate to rotate ninety degrees, so that the slot is re-aligned with the slide plate, and the slide plate can be automatically inserted into the slot to re-lock the locking ring plate, so that the switched effort-saving mode or the acceleration mode can be kept stable. The function of the slide plate automatically locking the locking ring plate improves the efficiency of switching the rotation adjustment component to the effort-saving mode or the acceleration mode.

[0058] Furthermore, the side wall of the fixed ring plate 1305 is provided with four slide grooves 13051 distributed in a cross shape, a slide plate 1308 is slidably arranged in the slide groove 13051, a slide bar 13052 of a T-shaped structure is connected to the inner wall of the slide groove 13051, a groove 13081 of a shape matching the slide bar 13052 is provided on the side wall of the slide plate 1308, and the slide plate 1308 is plugged and matched with the slide bar 13052 through the groove 13081; a plug post 13082 is connected to the side wall of the slide plate 1308, the plug post 13082 is arranged in the arc groove 13072, and the plug post 13082 is movably matched with the arc groove 13072; one end of the slide plate 1308 is set to a pointed structure in the shape of a matching slot 12041, and the slide plate 1308 is plugged and matched with the slot 12041;

[0059] Furthermore, the upper side wall of the gear rack 1302 is rotatably connected to a rotating column 3 1309, and the circumferential outer wall of the rotating column 3 1309 is connected to a tooth plate 1310. The circumferential outer wall of the tooth plate 1310 is provided with a plurality of outer tooth openings 3 13101 meshing with the outer tooth openings 2 13071, and one end of the rotating column 3 1309 is connected to a shaking handle 3 1311.

The wall sleeve is provided with a spring 13124, and the spring 13124 is an arc-shaped spring structure that matches the shape of the arc column 13123. A hole is opened on the side wall of the block 13112, and the block 13112 is slidably sleeved on the arc column 13123 through the hole. The spring 13124 is arranged between the block 13112 and the lower baffle 13122. In the present invention, when the crank handle 1311 is pushed upward to drive the tooth plate 1310 to rotate, the block 13112 on the circumferential side wall of the rotating plate 13111 slides along the arc column 13123 and cooperates with the lower baffle 13122 to compress the spring 13124 until the slide plate 1308 leaves the slot 1 After 2041, the base 1201 is rotated to achieve the purpose of switching the rotation adjustment component 12 to the labor-saving mode or the acceleration mode. During the switching process, the base 1201 can drive the locking ring plate 1204 to rotate, so that the slot 12041 of the locking ring plate 1204 is misaligned with the slide plate 1308. At this time, the shaking handle three 1311 can be released, and the block 13112 is subjected to the elastic force of the compressed spring 13124, and slides back along the arc column 13123, further driving the rotating plate 13111 to rotate back, and the gravity of the shaking handle three 1311 itself makes the tooth plate 1310 automatically rotate, and the rotation adjustment component 12 is turned to the left and right sides. The slide plate 1308 is driven to slide toward the outer wall of the circumference of the locking ring plate 1204 in one step until the rotation adjustment component 12 is switched to the labor-saving mode or the acceleration mode. The base 1201 drives the locking ring plate 1204 to rotate ninety degrees, so that the slot 12041 is realigned with the slide plate 1308. The slide plate 1308 can be automatically inserted into the slot 12041 to re-lock the locking ring plate 1204, so that the switched labor-saving mode or acceleration mode can remain stable. The function of the slide plate 1308 automatically locking the locking ring plate 1204 improves the efficiency of switching the rotation adjustment component 12 to the labor-saving mode or the acceleration mode.
