Description

The novel decorative bolt for handles

The utility model relates to the latch that a kind of door and window is used.

The thumb-latch that generally uses generally all is made of fixed head, stay rod pin and slotting ear at present, and wherein fixed head and slotting ear are separately fixed at the edge of door and window, and the shape of stay rod pin is a kind of to be

Shape, this shaped design is simple, but does not possess the handle shape, switch inconvenience, and easy deformation; Another kind of stay rod pin is

Shape, this shape is not yielding, and switch is convenient; But the defective of above-mentioned two kinds of latches is because the shape of stay rod pin makes overall dimensions bigger, thereby make cost of manufacture higher, the shape of stay rod pin also makes it can't increase ornamental shape-designing simultaneously, thereby make latch shape dullness outmoded, can't break through the convention of old-fashioned latch in the global design moulding.

The purpose of this utility model is to provide that a kind of switch is convenient, not yielding, cost of manufacture is low and novel decorative bolt for handles handsome in appearance.

The technical solution of the utility model is as follows: it comprises that fixed head, stay rod pin and base plate are inserted ear, wherein respectively there is the jack of a stay rod pin at the two ends up and down of fixed head, stay rod pin is " worker " font, its upper end is the handle end, the lower end is the inserted link end, and this inserted link end is inserted in the jack of fixed head when using.This shaped design of stay rod pin can make the design size of fixed head less, and the length of fixed head is shorter by 1/4th to 1/3rd than the fixed head of existing latch, therefore can reduce cost of manufacture; During making, utilize " worker " font structure of the handle end and the inserted link end of stay rod pin, the handle end of stay rod pin can be designed to various handle shapes or other decorative shape such as arc, arc surface, both made things convenient for switch, make whole handsome in appearancely again, have decorative effect.

Also fixed head can be designed to cylindrical shape, promptly the jack at two ends is a cylindrical shape up and down, and the lug in its stage casing also is a circular arc, only stays the interval that moves up and down for stay rod pin.This design can reach equally that switch is convenient, not yielding, cost is low and effect handsome in appearance.

The utility model overall construction design advantages of simple, peculiar, not yielding, and have the function that does not still influence the latch use when door and window is out of shape, long service life; The design of stay rod pin had both allowed user's switch more convenient, can make profile luxurious, attractive in appearance again, have modern decorative effect, and cost was low, was easy to produce, and can releases switch convenience, the luxurious high-grade latch attractive in appearance of profile.The utility model will become the new generation product that replaces old-fashioned latch, more be subjected to liking of user.

Further specify the utility model below in conjunction with accompanying drawing.

Fig. 2 is the schematic diagram of fixed head among Fig. 1;

Fig. 3 is the schematic diagram of stay rod pin among Fig. 1;

Fig. 4 is an overall structure schematic diagram of the present utility model;

Fig. 5 is the schematic diagram of fixed head among Fig. 4.

Fig. 1 to Fig. 3 has reflected the structure of the utility model embodiment, two jacks 2 and 3 are arranged on the fixed head 1, because stay rod pin 4 designs for umbrella shape, two jacks 2 and 3 with distance be that the moving up and down distance of stay rod pin 4 adds the width in stay rod pin 4 stage casings, therefore make the length of fixed head 1 shorter, save material, reduced cost.The handle of stay rod pin 4 upper ends end can arbitrarily be designed to various handle-shapeds by the producer, also carries out ornamental design, and this handle is held can Convenient switch, has the attractive, decorative effect again.For example the handle end can be designed to the umbrella shape handle of arc surface, spherical handle, triangle handle or various design attractive in appearance.Fixed head 1 also can add as various ornamental design such as butterfly, birds and flowers at its edge, coordinates mutually with the design of stay rod pin 4, makes the practicality of whole latch and decorative effect better.Base plate is inserted the another side edge that ear 5 is contained in door and window.The utility model is because fixed head is shorter, so only need adopt 4 screws to get final product when mounting plate, easy for installation, old-fashioned latch then needs 6 screw.

Fig. 4 and Fig. 5 are another embodiment of the present utility model, and fixed head 1 adopts cylindrical design, still has two jacks 2 and 3, and the design of stay rod pin 4 is same as the previously described embodiments, and cylindrical shape fixed head 1 production technology is simple, can directly adopt stainless steel tube to make.This structure not only is easy to produce, and cost is low, and the moulding unique and beautiful.
