Description

A kind of latch

Technical field

The utility model relates to building doors and windows field of accessories, and in particular, the utility model relates to the latch being applied to Switch for door and window.

Background technology

Latch is conventional switch locking device, but along with social progress, latch so the old-fashioned door and window be mated all more expensive by price, also more easy-to-use Novel window lockset substitutes, although take a broad view is all new-type lockset in one's power, but in fact in the broad area of China, the first-selection of old-fashioned door bolt still more people, the China that has its source in of this phenomenon is a regional economy extremely unbalanced country, especially urban residents' living condition is arduous for central and west regions resident, consuming capacity is weak, nearly all consumer goods all with inexpensive for choosing basis, lateral pin is firmly most share in occupation of rural market because of its low price, but current lateral pin on the market has following problem mostly, lateral pin is in use easily clashed into and is out of shape, in daily life, artificial or switch door and window rough under natural conditions all can accelerate the distortion of lateral pin, and the distortion of lateral pin directly affects its application life, in fact it is all repeatedly be subject to clashing into caused by rear distortion that most of lateral pin is scrapped, simultaneously, the factory technics backwardness relatively of current production lateral pin, the mode of production is extensive, product is muddled along, cause inefficiency, cost is relatively high.

Utility model content

An object of the present utility model is, provides a kind of latch, and solve latch and be subject to clashing into easy distortion, cost is higher, the problem that production efficiency is lower.

Above-mentioned purpose of the present utility model and other objects solve by the following technical programs:

The latch that the utility model provides, comprises plug housing and bolt rod, and described plug housing forms pilot hole by the domes of upside, and described bolt rod is installed in pilot hole, it is characterized in that:

Described plug housing is provided with handle guide plate, baffle plate, limiting plate and installing hole, described bolt rod is positioned at limiting plate, described bolt rod is provided with handle, described handle comprises the first vertical edge, second vertical edge, first arc limit, second arc limit, described first vertical edge length is greater than the space between pilot hole and bolt rod, the lower extreme point on described first arc limit is no more than the side of handle baffle plate, the length of described second vertical edge is greater than the first vertical edge, described second arc limit is positioned at immediately below handle guide plate side, described handle baffle plate is provided with the spheroform surface matched with described second arc limit.

The latch that the utility model provides, preferably, described baffle plate comprises the first symmetrical lower camber side, the second lower camber side and upper cambered surface.

The latch that the utility model provides, preferably, the fillet of described limiting plate and described plug housing and the fillet of described baffle plate and described plug housing are on the same line.

The latch that the utility model provides, preferably, the arc angle angle of described limiting plate is the half of pilot hole arc angle angle.

Advantage of the present utility model and beneficial effect are:

1. the latch that provides of the utility model, the mode that its handle inner side edge takes vertical edge arc limit staggered, arranges corresponding shape at common impingement position, effective alleviates the infringement of clashing into some key position;

2. the latch that provides of the utility model, also contemplates the length relation of handle inner side edge arch section and vertical-shaped part, rises and saves material to the limit, object simultaneously easy to use;

3. the latch that provides of the utility model, baffle plate adopts two kinds of cambered surfaces collocation to be shaped, and when baffle plate and bolt rod collide, reduces the destruction of impact to both sides' shape;

4. the latch that provides of the utility model, the fillet of limiting plate and baffle plate and plug housing is established on the same line, is convenient to produce, and adds efficiency during production.

Accompanying drawing explanation

Carry out describing in detail or preferably to preferred embodiment of the present utility model below in conjunction with accompanying drawing, wherein,

Fig. 1 is schematic diagram of the present utility model;

Fig. 2 is the lateral view of baffle plate;

Fig. 3 is the lateral view of handle guide plate;

Plug housing 1, bolt rod 2, pilot hole 3, handle guide plate 4, spheroform surface 41, handle 5, the first vertical edge 51, first arc limit 52, second vertical edge 53, second vertical edge 54, baffle plate 6, the first lower camber side 61, second lower camber side 62, upper cambered surface 63, limiting plate 7, installing hole 8.

Detailed description of the invention

With reference to accompanying drawing, the latch that the utility model provides, comprise plug housing 1 and bolt rod 2, plug housing 1 forms pilot hole 3 by the domes of upside, bolt rod 2 is installed on pilot hole 3 li, plug housing 1 is provided with handle guide plate 4, baffle plate 6, limiting plate 7 and installing hole 8, bolt rod 2 is positioned at limiting plate 7, the existence of limiting plate can make bolt rod have longer operating range, also can be alleviated the collision of the domes of bolt rod and formation spacing hole by its whole medial surface when there is hard hit, bolt rod 2 is provided with handle 5, handle 5 comprises the first vertical edge 51, second vertical edge 53, first arc limit 52, second arc limit 54, first vertical edge 51 length is greater than the space between pilot hole 3 and bolt rod 2, first arc limit is exclusively used in the collision with domes, even if through repeatedly hard hit, also a whole larger arc limit is formed due to the existence on the second arc limit, the use of latch is not had an impact, the lower extreme point on the first arc limit 53 is no more than the side of handle baffle plate 4, if the lower extreme point on the first arc limit exceeds this side, the ability that then handle baffle plate matches with handle can die down, the length of the second vertical edge 53 is greater than the first vertical edge 51, second arc limit 54 is positioned at immediately below handle guide plate 4 side, the mode that handle inner side edge takes vertical edge arc limit staggered, corresponding shape is arranged at common impingement position, effectively alleviate the infringement of clashing into some key position, simultaneously, also contemplate the length relation of handle inner side edge arch section and vertical-shaped part, rise and save material to the limit, object simultaneously easy to use, handle baffle plate 4 is provided with the spheroform surface 41 matched with the second arc limit 54.

Baffle plate 6 comprises the first symmetrical lower camber side 61, second lower camber side 62 and upper cambered surface 63, and baffle plate adopts two kinds of cambered surface collocation to be shaped, and when baffle plate and bolt rod collide, reduces the destruction of impact to both sides' shape.

On the same line, the fillet of limiting plate and baffle plate and plug housing is established on the same line, is convenient to produce, and adds efficiency during production for the fillet of limiting plate 7 and described plug housing 1 and the fillet of baffle plate 6 and described plug housing 1.

The arc angle angle of limiting plate 7 is the half of pilot hole 3 arc angle angle, in such cases, need not carry out the replacement of mould, add production efficiency during production.

According to the technical solution of the utility model, when not changing connotation of the present utility model, those of ordinary skill in the art can propose multiple frame mode of the present utility model.Therefore following detailed description of the invention and accompanying drawing just illustrating the technical solution of the utility model, and should not be considered as of the present utility model all or the restriction be considered as technical solutions of the utility model or restriction.
