Abstract

The utility model discloses a pin device which is suitable for double sides of an aluminum alloy door. The utility model aims to provide a pin for double sides of the aluminum alloy door, which has the advantages of simple structure, easy use, easy manufacture and low cost. The utility model is composed of a lever, a fulcrum shaft, and a pin, wherein, the lever is a thin plate member and provided with a handle, a corner, a fulcrum hole and a slotted hole; the pin presents an inverted U shape, one end is long and the other end is short, and the inner side presents an oblique angle; the fulcrum shaft is an ordinary fastening bolt. The utility model can be widely used for doors of all places that need 'open ' and 'the pin ' both inside and outside, particularly the aluminium alloy door.

Description

The two-sided latch in aluminium alloy door

(1) technical field

The utility model belongs to the five metals lockset kind, is a kind of two-sided latch that the aluminium alloy door uses that especially is fit to.

(2) background technology

At present, be suitable for that wooden door uses, have the spherical lockset of two-sided latch function complete, but the similar two-sided latch that is suitable for the aluminium alloy door is not seen always.Can ball catch be transplanted and substitute so? can not, because should put into the interior garden column diameter partly of door by lock, all be unified 52 millimeters, in other words, must get on the door 52 millimeters the hole, obviously, this without a doubt, but concerning " door limit " has only the aluminium alloy door of 50 mm wides, has but become the difficult problem that can't realize concerning the wooden door of " door limit " broad, the two-sided mortise lock that therefore can be used for such also belongs to " blank " at present.For these reasons, the aluminium alloy door, especially in accordance with regulations must be to the aluminium alloy door (as transformer room, some public place etc.) of external-open, damage door and glass (or other what reasons) owing to be afraid of wind, often pinning inside, messenger detains Men Zaikai, opened and sailed again, go out certainly the room also bound other people with seeing the pin door, so again and again, promptly waste the time, influenced work again.

(3) summary of the invention

The purpose of this utility model is, give the aluminium alloy door of being in fashion at present, provide a kind of reasonable in design, with low cost, easy to use, install simply, reduce again the structural strength of door, two-sided bolt device to be to separate worried and inconvenient that all multi-users cause therefrom.

For achieving the above object, the utility model is taked following technical scheme:

This device by lever 1, penetrate branched shaft hole 4 and be fixed in the fulcrum 3 on the attacker 9 and wear the latches 6 that hang in the slotted hole 7 and form, described lever 1 is a sheet member, self is provided with to press hand 2, turning 5, branched shaft hole 4 and slotted hole 7; Described latch 6 is inverted U-shaped, and two jiaos one is long and the other is short, and the inboard is the oblique angle.

The long angle of described latch 6 is preferably the 10-30 millimeter with the difference at short angle; The Center Length of described slotted hole 7, in the time of should being not less than pin door state, latch 6 between the fixed gate 8 apart from length.

During the room outward opening door, press hand 2, lever is lifted top dead centre with latch 6 thereupon, and this moment, attacker 9 was withdrawed from short angle, and door is opened; During room export trade door,, click by hand 2 and also unclamp immediately, can close from untie-sell in the effect Xiamen of gravity earlier with the door leaf alignment.When opening the door within doors, hand is pinched on the exposed portions serve of lever 1 and is carried, and attacker 9 is withdrawed from short angle, and door is opened.In like manner, insert the back door bolt.Because " opening " and " pin " that can both control gate in the room,, thereby realized this Design of device purpose in the room outside.

The enforcement of this device sending to for huge numbers of families easily simultaneously, also will bring good economic benefits for manufacturing enterprise.This device has been compared following advantage with ball catch:

1, purposes is wide.The latter can only be used for " single open-door " or other is fanned door securing " clamshell doors ", and this device does not then need additional conditions, and " singly opening ", " splitting " all can.

2, the intensity that simply and not reduces door is installed.The latter needs to dig out big hole respectively on " door limit " and " doorway ", and not only trouble has also influenced the intensity of existing facility.This device only bores an aperture and gets final product on the attacker, the intensity of opposite house is at all harmless.

3, with low cost.Latter's market price is a 15-80 unit, and 0.8 yuan of the material cost deficiency of this device, and manufacturing process is simple, and 1.3～1.8 yuan of finished product total costs, sale price can arrive 5～8 yuan, have very big price competitiveness, thereby promise well.

(4) description of drawings

Fig. 1 is front view (state after the position is in and opens the door among the figure).Fig. 2 is right view (position still has by power among the figure, is in to be about to out or the state when selling).Fig. 3 is vertical view (position is in pin door state among the figure).Among the figure: 1-lever, 2-press hand, 3-fulcrum, 4-branched shaft hole, 5-turning, 6-latch, 7-slotted hole, 8-fixed gate, 81-dodge gate, 9-attacker.

(5) specific embodiment

Below in conjunction with drawings and Examples, the utility model is further described.Shown in Figure 3 as Fig. 1, described lever 1 is the steel sheet of 1.5-2 millimeters thick, itself can fold by hand 2 and turning 5 and process branched shaft hole 4 and slotted hole 7, the length of slotted hole is the 30-40 millimeter, the effect at turning 5 be guarantee lever 1 stretch into crack between a door and its frame partly, be in the center of fixed gate 8 and dodge gate 81 all the time.Slotted hole 7 still makes latch 6 run into two doors and when moving after stopping except that connecting latch 6, and effect that can also vertical lifting one segment distance is to guarantee the insertion depth of latch 6 to greatest extent.Described latch 6 should select for use the round steel of Φ 6 to make, and top is semicircle shape, in order to autobalance.When latch 6 was in top dead centre, attacker 9 was withdrawed from short angle, and long angle is because of having more the 10-30 millimeter so can not withdraw from, and this measure has guide effect concurrently, and the oblique angle at two ends is similarly guiding and establishes.Described fulcrum 3 is common screw; Described attacker 9 is original setting in the aluminium alloy door, when boring the fixing hole of system fulcrum 3 thereon, should note choosing the best point of realizing function.In addition, must be by the long angular direction of the wrap direction at hand 2, turning 5 and latch 6 jointly towards fixing with it fixed gate 8 one sides (showing) as Fig. 3, if change direction into dodge gate 81 sides, then the direction at above-mentioned several places must be turned over turnback simultaneously.
