Utility model content
The applicant, for above-mentioned existing issue, is studied improvement, and a kind of Novel fireproof lock construction is provided, and has cost low, and quick and convenient, simple in structure advantage is installed.
The technical scheme that the utility model adopts is as follows:
A kind of Novel fireproof lock construction, comprise the lock body being connected to form by drain pan and lid shell, a side at described lock body connects lock panel, in described drain pan, install that latch bolt is found a place to live in, the first drive screw pin and the second drive screw pin, one end that described latch bolt is found a place to live in connects latch bolt, the find a place to live in other end bending of described latch bolt extends to form barrier plate, and flange is also set on barrier plate; On described latch bolt is found a place to live in, centered by the transverse axis of finding a place to live in by described latch bolt, be arranged symmetrically with two crotches, spring housing is contained on described the first drive screw pin, the two ends of described spring stretch out respectively and with described crotch butt; Left shift fork and right shift fork are also installed on described latch bolt is found a place to live in, between described left shift fork and right shift fork, are installed holly strip; On described lid shell, also have two for coordinating the spacing hole of described flange, described spacing hole is rectangle.
Its further technical characterictic is:
Described latch bolt is found a place to live in as " U " shape, and described barrier plate and described latch bolt are arranged vertically between finding a place to live in each other;
On described left shift fork and right shift fork, have the lockhole inserting for handle, each lockhole is arranged concentric, and described lockhole is rhombus.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, easy for installation, utilize handle to realize the relative motion of left shift fork and right shift fork, the baffle plate butt of finding a place to live in by each shift fork and latch bolt, latch bolt is got away and drive the displacement of latch bolt, thereby realize the switching of door, the setting of spacing hole prevents that latch bolt from finding a place to live in and the over-travel of latch bolt, has effectively guaranteed the life-span of each part, has that cost is low, easy-to-install advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional structure schematic diagram of A-A direction in Fig. 1.
Wherein: 1, lock panel; 2, latch bolt; 3, spring; 4, the first drive screw pin; 5, drain pan; 6, left shift fork; 7, holly strip; 8, right shift fork; 9, lid shell; 901, spacing hole; 10, latch bolt is found a place to live in; 101, installing hole; 11, crotch; 12, barrier plate; 121, flange; 13, the second drive screw pin; 14, lockhole.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, a kind of Novel fireproof lock construction, comprise the lock body being connected to form by drain pan 5 and lid shell 9, a side at lock body connects lock panel 1, on lock panel 1, have two installing holes 101, at find a place to live in the 10, first drive screw pin 4 and the second drive screw pin 13, the second drive screw pin 13 of the interior installation latch bolt of drain pan 5, be two, above-mentioned the second drive screw pin 13 and the first drive screw pin 4 form triangles and arrange.Latch bolt finds a place to live in 10 for " U " shape, in find a place to live in one end of 10 of latch bolt, connects latch bolt 2, and latch bolt 2 is when the utility model is closed in lock panel 1, and latch bolt 2 is separated with lock panel 1 when opening.Latch bolt 10 other ends bendings of finding a place to live in extend to form barrier plate 12, flange 121 is set on barrier plate 12, barrier plate 12 and latch bolt are found a place to live in and 10 are arranged vertically each other, in latch bolt, find a place to live on 10, centered by latch bolt is found a place to live in 10 transverse axis, be arranged symmetrically with two crotches 11, spring 3 is sleeved on the first drive screw pin 4, the two ends of spring 3 stretch out respectively and with crotch 11 butts; In latch bolt, find a place to live on 10 left shift fork 6 and right shift fork 8 are also installed, between left shift fork 6 and right shift fork 8, install holly strip 7.Between described left shift fork 6 and right shift fork 8, install holly strip 7; On described left shift fork 6 and right shift fork 8, have the lockhole 14 inserting for handle, each lockhole 14 is arranged concentric, and described lockhole 14 is rhombus.On lid shell 9, also have two for the spacing hole 901 of mating flanges 121, spacing hole 901 is rectangle.
Specific works process of the present utility model is as follows:
As shown in Figure 1, latch bolt 2 is because the effect of spring 3 is in stretching out state, by handle (not shown) is stretched into the lockhole 14 of left shift fork 6 or right shift fork 8 interior after, thereby rotating handle drives left shift fork 6 or right shift fork 8 to rotate, above-mentioned left shift fork 6 or right shift fork 8 contact with barrier plate 12 in rotation process, effect by power moves right barrier plate 12 as shown in Figure 1, flange 121 also moves right in spacing hole 901, because barrier plate 12 and latch bolt are found a place to live in and 10 are connected, therefore drive latch bolt find a place to live in 10 and latch bolt 2 move right, thereby make lock panel 1 separated with latch bolt 2, thereby realize operating personnel in Men Nei or the unlatching of opposite house outdoors, because being arranged in latch bolt, crotch 11 finds a place to live on 10, itself and spring 3 butts, therefore in motion process, the movement of crotch 11 certainly will drive spring 3 stress deformations, when operating personnel unclamp after handle, spring 3 is no longer stressed, it recovers original shape and drives crotch 11 and latch bolt to find a place to live in 10 to left dislocation, thereby again realized latch bolt 2 and run through lock panel 1, realized and closed locking state, simultaneously due to find a place to live in 10 displacement of latch bolt, make barrier plate 12 and flange 121 also servo-actuated, flange 121 in the interior movement of spacing hole 901 until with one end butt of spacing hole 901, prevent that displacement is excessive, thereby protected latch bolt 2, latch bolt is found a place to live in application life of 10.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
