Specific embodiment

Middle embodiment is described further utility model with reference to the accompanying drawing.

A kind of bottom beam lock as shown in Figure 1 to Figure 3, including lock body 1, lock body 1 are equipped with key driving mechanism 11 and lock The torque arm 12 of 11 side of spoon driving mechanism, 12 end of torque arm are provided with interconnecting piece 121, and interconnecting piece 121 is equipped with limit body 2, limit Position body 2 is mobile relative to doorframe 3 with torque arm 12, to realize the sealed of door body and open.Torque arm 12 is located at 11 liang of key driving mechanism Side, key driving mechanism 11 drive torque arm 12 to translate by Rack and pinion mechanism.Key driving mechanism 11 drives torque arm 12 flat It moves, and then limit body 2 is driven to translate.Under locked state, limit body 2 is translated into doorframe 3, and limitation limit body 2 is equipped in doorframe 3 The block piece moved up, the block piece can be the aperture that Horizontal limiting bar is also possible on vertical plate.

Interconnecting piece 121 is located at 1 outside of lock body, and 121 side of interconnecting piece is equipped with to the bending part extended far from 1 side of lock body 122.Lock body 1 includes backboard 13, and backboard 13 is equipped with opening 131, and bending part 122 passes through opening 131.11 band of key driving mechanism Dynamic torque arm 12 translates, and bending part 122 moves in opening 131, and the horizontal displacement of 131 sides of opening limitation bending part 122 avoids Torque arm 12 translates that amplitude is excessive, and 131 bottom and upper segment of being open limits teetertottering for torque arm 12.

In the present embodiment, interconnecting piece 121 is plate structure, and limit body 2 is tubular structure, and interconnecting piece 121 is inserted into limit body 2 Internal and screw is fixed on limit body 2.Interconnecting piece 121 is rectangular slab, and the cross sectional shape of limit body 2 is rectangle, interconnecting piece 121 It is bonded with 2 inner surface of limit body.The width of rectangle interconnecting piece 121 and the equivalent width of 2 inner sidewall of limit body, interconnecting piece 121 The upper and lower surfaces of 2 inside of bottom and upper segment and limit body be bondeds, only need both at this time a screw fix can be realized it is stable Transmission, since the junction of interconnecting piece 121 and limit body 2 is between lock body 1 and door bottom beam 5, substantially reduces installation Time simultaneously reduces installation operation difficulty.

Lock body 1 includes panel 14, is equipped with aperture 141 with 121 relative position of interconnecting piece on panel 14.Panel 14 and backboard 13 Lock-shell structure is constituted, key driving mechanism 11 and torque arm 12 are located in lock housing, and backboard 13 is located at close to 5 side of door bottom beam, face Plate 14 is located remotely from 5 side of a bottom beam.When installation, lock body 1 is fixed on a bottom beam 5,2 sets of limit body of tubular are in interconnecting piece On 121, by aperture 141 by limit body 2 and 121 screw connection of interconnecting piece.Aperture 141 is equipped with chock 4, makes after assembling Aperture 141 is blocked with chock 4, foreign matter is avoided to enter lock body 1.

1 side of lock body is equipped with door bottom beam 5, and door bottom beam 5 is stuck in doorframe 3, and the bending part 122 of torque arm 12 passes through 5 side of bottom beam Opening on plate, limit body 2 are located in door bottom beam 5, and door bottom beam 5 can be moved back and forth along 3 extending direction of doorframe.

Described above is only the explanation to utility model, so that those of ordinary skill in the art's can completely implements we Case, but be not the limitation to utility model, those skilled in the art are can according to need after reading this specification to this Embodiment makes the modification of not creative contribution, these are all without creative modification, but as long as in utility model All by the protection of Patent Law in scope of the claims.
