【正文】 tch accounted for a very important role, and the requirements of switch people more and more is also high. Currently has already been used switches and magic touch equipment only satisfies the basic requirements of open and close, but magic touch need to use, easy to permanent mag demagization, which increased the cost, and cannot guarantee the reliability of the work. And because of its structure, only applicable to glass doors this occasion, not suitable for wooden cupboard door, and cannot excessive force. In order to overe the disadvantages of magic touch, we designed a kind of simple structure, the price is cheap, reliable work, can apply wooden cupboard door, and can withstand greater impact of new semiautomatic cupboard door switch. If applied in ambry equipment, can avoid cooking process ambry is smeary, leave hard purify can be more greatly satisfy the humanized demands. 2 We design the new semiautomatic cupboard door switch switch all rely on two movements to realize push cupboard door Design were used in spring, lock slider, positioning the slider transmission slider, connecting rod, flexible thimble, lock and dowel pin structure, simple and convenient operation, the mechanization. If the cupboard door and touch ponent as the original move pieces, will realize lock action which the ponent is called follower, when the original move a effect, through the transmission system of driven follower motion, realize the switch cupboard. When closing, promote cupboard door, spring contact and promote left transmission slide motion, and two transmission slider consolidation of link promote positioning the slide motion, and the lock slider separation, lock and lock slider unifies, plete closed action。 那么，是否能設計出一種只需輕磕柜門就能實現(xiàn)柜門開關動作的新型半自動開關，這樣免除了老式柜門把手清洗、替換的工作，而且使用起來更加方便舒適。這樣也就要求在柜門內表面有一個可以用來實現(xiàn)鎖扣動作的構件。柔性頂針前端具有凹槽，鎖扣滑塊中部開有朝向定位滑塊的凹槽，右向端部被加工成楔形。 8 經過關門動作 1 之后，人手離開柜門，柜門將在彈簧 2 的作用下向外運動。 9 圖 4 開門動作 1 示意圖 柜門在人手的推動下向里運動，此時柔性頂針將推動傳動 滑塊 1 向里運動，在這個時間內，將發(fā)生以下動作： （ 1）柔性頂針推動傳動滑塊 1 向里移動，柔性頂針發(fā)生彎曲變形； （ 2）傳動滑塊 1 通 過柱銷 1 驅動連桿作平面運動； （ 3）連桿通過柱銷 2 推動傳動滑塊 2 向外移動，同時通過柱銷 3 推動定位滑塊向外移動； （ 4）在上述運動的同時，鎖扣也向里運動，因為鎖扣與鎖扣滑塊接觸面為楔形 【 7】 ，所以鎖扣滑塊會在鎖扣的推動下向左運動，直至其中部開口凹槽正對定位滑塊前端部。全機械式，可以承受比較大的沖擊，工作穩(wěn)定可靠。為此，我們致以最真摯的謝意。 由于處于試驗階段，我們的設計還存在些許不足，尚須改進。 （ 6）這次動作直到柜門與柜貼緊為止。 圖 3 關門動作 2 示意圖 將發(fā)生以下運動： (1)鎖扣滑塊右端部始終與鎖扣緊貼，當具有楔形面的鎖扣滑塊右端部進入到鎖扣前端的凹槽之后，柜門將停止向外的運動。 關門 當?shù)谝淮侮P上柜門時，如圖 2 所示。解開鎖扣的能量也需要由開門的動作提供。不過，在一些家具設備中，比如櫥窗，書柜之類，已經有一種裝置能夠實現(xiàn)上述功能，它就是磁碰。t have the hinge, this is the new hinge manufacturing provides market. This switch cupboard door window for such woodiness semiautomatic switches forward a new institution, fill the blank, has high practical, has a wide application prospects. Key words: Semiautomatic。 我們所設計的新型半自動柜門開關的開關兩個動作都是依靠
