Detailed Description

The invention will be further described in the following with reference to specific embodiments thereof,

as shown in fig. 1-5, the lock body is composed of a housing 11, a back plate 14, a latch 13, a square core 15, a push plate 16 and a handle 18, wherein the handle 18 extends into the housing 11 through a notch 117 and is connected to the push plate 16, the push plate 16 drives the square core 15 to rotate in the forward movement process, the square core 15 further links with the latch 13 to retract the latch 13 into the lock hole 12, and after the handle 18 is loosened, the latch 13 is ejected out of the lock hole 12 under the action of a torsion spring 19. For the fire control passageway lock body of push-down formula, the lock body among the technical scheme of this application need not the push rod and relies on handle 18 alone can realize opening and closing of spring bolt 13 to the direction that its spring bolt 13 stretches out is similar with normal lock body structure in the side of casing 11, and it can be more handy to use for the spring bolt 13 is the fire control passageway lock body that stretches out from the front end, more accords with normal use custom.

Further, a first sliding area 112, a second sliding area 114 and a pin hole 113 are arranged in the housing 11, the latch 13 is limited in the first sliding area 112 to move, the push plate 16 is limited in the second sliding area 114 to move, the square core 15 is limited in the pin hole 113 to rotate, the square core 15 links the push plate 16 and the latch 13 through a first trigger end 151 and a second trigger end 152 on the periphery of the square core 15 to function as a transfer member, the first trigger end 151 abuts against a vertical plate 131 of the latch 13, the second trigger end 152 abuts against the front end edge of the push plate 16, a hole for inserting a square rod is further formed in the square core 15, and the square core is not numbered in related figures and can be matched with a key panel.

Furthermore, a positioning round hole 141 and a positioning square hole 142 are formed on the back plate 14, the positioning round hole 141 corresponds to the pin hole 113 on the housing 11 to position the square core 15, the positioning square hole 142 corresponds to the second sliding area 114 to position the push plate 16, and the length of the positioning square hole 142 is greater than the length of the positioning bump 161 on the push plate 16 because the push plate 16 needs a space to slide.

Further, the back plate 14 is fixed to the threaded hole 118 of the housing 11 through a through hole 143 of the back plate 14 by a fastener, typically a screw, and a latch 119 is formed at one side of the housing 11, and the back plate 14 is fixed to the housing 11 by the latch 119 and then fastened by the fastener.

As shown in fig. 6, the vertical plate 131 of the latch 13 is provided with a horizontal groove 132, one end of the torsion spring 19 abuts against the side wall of the housing 11, and the other end abuts against the horizontal groove 132 of the vertical plate 131, because one end of the torsion spring 17 abutting against the housing 11 is always kept stationary, and one end of the torsion spring abutting against the vertical plate 131 always rotates along with the movement of the latch 13, the horizontal groove 132 equivalently limits the up-and-down movement of the torsion spring 17 abutting against one end of the vertical plate 131, so that the position of the torsion spring 17 cannot be deviated.

As shown in fig. 2, 4 and 5, a first positioning end 115 is formed in the housing 11, a second positioning end 162 is formed on the push plate 16, a spring 19 is disposed between the first positioning end and the second positioning end, and the spring 19 assists the push plate 16 to drive the grip 18 to return after the grip 18 is released.

Further, to fix the spring 19, a stopper 116 is formed at both sides of the first positioning end 115.

As shown in fig. 8, the lock body in the technical solution of the present application can also form a complete fire fighting access lock with a connecting rod positioner 2, and only the connecting rod 3 needs to be inserted between the lock body of the fire fighting access lock and the 2 handle 18 of the connecting rod positioner 1, and the lock body and the handle are connected, so that when the body applies pressure to the connecting rod 3, the fire fighting access lock is opened.

Furthermore, when the fire fighting access lock body 1 and the handle 18 on the connecting rod positioner 2 are installed, the handles are on the same horizontal line, and the blocking feeling of the installation and the use of the connecting rod 3 is avoided.

Further, the handle 18 is provided with a fastening pin hole 182 for fastening the link 3.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
