Abstract
A kind of Hinge for window, comprise guide rod, to be set in guide rod and can the expansion link of movement in guide rod, described guide rod inwall is hinged with a rotary block, the two ends of described rotary block are provided with the rake tooth inwardly concaved, guide rod inwall corresponding above rotary block is provided with opening I, described expansion link is provided with the push rod corresponding with rotary block, expansion link inwall corresponding above described push rod is provided with opening II, during described rotary block horizontal positioned, rake tooth bottom lower than push rod bottom.The utility model realizes opening or closing of window by guide rod and expansion link relative motion, and after window pushs out completely, the folding being realized window by rotary block and rake tooth is located, and scientific structure design is reasonable, and use safety, product is durable in use.
Description
Technical field
The utility model relates to a kind of window fittings, is specifically related to a kind of Hinge for window.
Background technology
The existing member structure pushing away Hinge for window and mostly be complicated, if the patent No. is for shown in the utility model patent of 200920260549.9, it comprises many cursors and spacer.Although this structure can realize opening and locating of window well, its complex structure, cost of production is high, is unfavorable for large-scale promotion.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of structure simple, use simple Hinge for window.
The utility model solves the technical scheme that its technical problem adopts:
A kind of Hinge for window, comprise guide rod, to be set in guide rod and can the expansion link of movement in guide rod, described guide rod inwall is hinged with a rotary block, the two ends of described rotary block are provided with the rake tooth inwardly concaved, guide rod inwall corresponding above rotary block is provided with opening I, described expansion link is provided with the push rod corresponding with rotary block, expansion link inwall corresponding above described push rod is provided with opening II, during described rotary block horizontal positioned, rake tooth bottom lower than push rod bottom.
In the utility model, the end of described guide rod be provided be connected with window or window frame be rotationally connected position I.
In the utility model, the end of described expansion link be provided be connected with window or window frame be rotationally connected position II.
The beneficial effects of the utility model are: the utility model realizes opening or closing of window by guide rod and expansion link relative motion, after window pushs out completely, the folding being realized window by rotary block and rake tooth is located, and scientific structure design is reasonable, use safety, product is durable in use.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated:
Fig. 1 is external structure schematic diagram of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the schematic diagram of window when opening;
Fig. 4 is the action flow chart that window needs when closing: the structural representation that Fig. 4 (a) goes back for the first time for window, the structural representation that Fig. 4 (b) walks toward outside for window, the structural representation that Fig. 4 (c) goes back when closing again for window.
Detailed description of the invention
Referring to figs. 1 through Fig. 4, a kind of Hinge for window provided by the utility model, comprise guide rod 1, to be set in guide rod 1 and can the expansion link 2 of movement in guide rod 1, guide rod 1 and expansion link 2 are groove-like, described guide rod 1 inwall is hinged with a rotary block 3, the two ends of described rotary block 3 are provided with the rake tooth 31 inwardly concaved, guide rod 1 inwall corresponding above rotary block 3 is provided with opening I 11, described expansion link 2 is provided with the push rod 4 corresponding with rotary block 3, expansion link 2 inwall corresponding above described push rod 4 is provided with opening II 21, during described rotary block 3 horizontal positioned, rake tooth 31 bottom lower than push rod 4 bottom.
Further, for convenience of being connected with window, the end of described guide rod 1 be provided be connected with window or window frame be rotationally connected position I 5, the end of described expansion link 2 be provided be connected with window or window frame be rotationally connected position II 6.
When window opened by needs, expansion link 2 moves outward until push rod 4 withstands in the rake tooth 31 of rotary block 3 one end, because the center of rotation of rotary block 3 is not in the direction of motion of push rod 4, therefore rotary block 3 rotates and the rake tooth 31 of rotary block 3 other end is stretched out from opening II 21 under the effect of push rod 4, when push rod 4 inserts in rake tooth 31 completely, rotary block 3 cannot be rotated further, and expansion link 2 also cannot continue to stretch out outward, play spacing effect, now window is completely pushed out of.When needs closedown window or window are subject to external wind, when will back move, expansion link 2 back moves, inwall on the right side of opening II 21 withstands on the rake tooth 31 that stretched out, rotary block 3 is rotated further, until the inwall of opening II 21 side inserts in rake tooth 31 completely, rotary block 3 is stuck and cannot continues to rotate, and simultaneous retractable bar 2 also cannot be gone back again; Now, should again promote window to move outward, expansion link 2 is stretched out outward, push rod 4 promotes rotary block 3 to be continued to rotate, until the top of rotary block 3 withstands in opening I 11 inner left wall, and then promotion window back moves, make expansion link 2 back shrinkage, inwall on the right side of opening II 21 promotes rotary block 3 and is rotated further, and make rotary block 3 parallel with expansion link 2 upper inside wall, such expansion link 2 can be regained completely.Because rotary block 3 relative starting position turns over 180 °, when needs are windowed again, repeat above-mentioned steps.
The foregoing is only preferred embodiments of the present utility model, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection domain of the present utility model.
