Abstract

The utility model aims to provide a crescent lock seat for doors and windows. The crescent lock seat comprises a lock seat, a lock plate and a handle, wherein a rivet and a protruding end which extends out after the rivet penetrates through the lock plate are arranged on the handle, and the handle is rotatablely arranged on the lock seat through a supporting point of the protruding end; the protruding end of the rivet is penetrated in and connected with a locking block which is used for positioning the lock plate and the handle on the lock seat; positioning grooves for placing two elastic sheets are formed on the lock seat, and the locking block is clamped between the two elastic sheets; and the lock seat is formed by punching a stainless steel sheet. By the crescent lock seat, the phenomena of high energy consumption and low efficiency of the conventional pouring process are avoided, the two elastic sheets are easily placed in the positioning grooves, and the production efficiency is effectively improved.

Description

A kind of door and window crescent lock pedestal

Technical field

The utility model relates to a kind of crescent lock field of door and window, relates in particular to a kind of crescent lock pedestal that is applied to door and window.

Background technology

At door and window lock body is set, both helped fixing movable window, can realize windproof, antitheft purpose again, present crescent lock is typically provided with lock, jam plate and handle, handle is crossed jam plate by the rivet cross-under and is integrated shape, a convex at jam plate stretches out an end, and the protruding end by this rivet is installed on the lock again, makes handle do 360 degree rotations by this lock.

The traditional handicraft of known lock body mainly is that metal fever is melt into liquid, again liquid fall is injected the in-mold molding that sets in advance intact shape, be commonly called as and be " cast-type die casting " technique, yet, for this a kind of technique, need a large amount of coal burnings, and directly the die-cast metal of cast-type is highly brittle weak easily broken, the Push And Release of repeatedly counting through the people that dare not accept moves, that is to say that people want to open window or during the action of closing, will rupture easily or damage, namely have to it is replaced.

So, highly energy-consuming, expensive, inefficient problem are particularly outstanding, and this energy-conserving and environment-protective policy that advocated now runs in the opposite direction, and must ban this old-fashioned production technology.

Summary of the invention

The purpose of this utility model is to provide a kind of door and window crescent lock pedestal, and its main purpose is by the impact style of smart steel being banned traditional cast extrusion process, and a kind of sturdy and durable, efficient door and window crescent lock pedestal of production finally can be provided.

The utility model comprises: lock, jam plate and handle, wherein handle is provided with rivet and passes the extended end that protrudes out behind the jam plate by rivet, but protruding out the end fulcrum by this is installed on the lock rotatably, and protrude out by described rivet that one of cross-under of end is used for jam plate, handle is positioned the stop block on the lock, described lock is provided with the locating slot of placing for two shell fragments, and two shell fragments are in the both sides of described stop block.

Described locating slot is two, and be positioned at described stop block two ends, the left and right sides.

Described shell fragment is the little side's bar of straight steel.

Described shell fragment is the Thin Elastic steel disc.

Described stop block periphery is along becoming run-track shaped, and the up and down both sides of stop block are straight flange, and the left and right sides is circular-arc.

Described locating slot is interior straight flange groove, the movable smooth shell fragment of a straight flange of locating slot, movable smooth another shell fragment of another straight flange of locating slot.

One of described rivet is used for the baffle plate of described shell fragment location.

The beneficial effects of the utility model are: lock is provided with the locating slot of placing for two shell fragments, be held on stop block between two shell fragments, lock is that smart steel disc is stamped to form, avoid the highly energy-consuming of traditional pouring technology, inefficient phenomenon, simultaneously, two shell fragments simply easily are placed in the locating slot, Effective Raise production efficiency.

Fig. 3 is the stereogram of whole crescent lock.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises: lock 1, jam plate 2 and handle 3, wherein handle 3 is provided with rivet 31, pass the jam plate 2 rear extended ends that protrude out by rivet 31, but protruding out the end fulcrum by this is installed on the lock 1 rotatably, and be used for jam plate 2 by one of the cross-under of end that protrudes out of described rivet 31, handle 3 is positioned the stop block 32 on the lock 1, described lock 1 is provided with the locating slot 11 of placing for two shell fragments 4, two shell fragments 4 are clamped in the both sides of described stop block 32, as shown in Figure 2, described stop block 32 peripheries are along becoming run-track shaped, the up and down both sides of stop block 32 are straight flange, and the left and right sides is circular-arc.

Further, described locating slot 11 is two, be positioned at described stop block 32 two ends, the left and right sides, this shell fragment 4 is the little side's bar of straight steel or can be the Thin Elastic steel disc, because locating slot 11 is interior straight flange groove, the movable smooth shell fragment 4 of one straight flange of locating slot 11, movable smooth another shell fragment 4 of another straight flange of locating slot 11.

As shown in Figure 3, be fixed in the locating slot 11 baffle plate 5 that is used for described shell fragment 4 location of described rivet 31 riveted joints in order to make shell fragment 4.

It should be noted that, two back gauges of described locating slot 11 are identical with two straight flanges of stop block 32, two shell fragments 4 are held on two straight flanges of stop block 32, rotation by shell fragment 4 restriction stop blocks, and when artificial rotary handle 3, have rotating effect after making the arc-shaped edges of stop block 32 contact two shell fragments 4, handle 3 is rotated back and forth, this belongs to known technology.

Above-mentioned specific embodiment only is the preferably specific embodiment of the utility model effect, and all or crescent lock pedestals of being equal to identical with this structure are all in the application's protection domain.
