Abstract
Provided is a friction tongue lock body reversing structure. An oblique plane is formed on the surface, opposite to a touching tongue of a friction tongue, of a friction tongue base. The displacement of a left vertical edge of a boss when the supporting driving boss of the touching tongue of the friction tongue swings from a position making contact with a side plate to a position where the boss leans on the oblique plane is larger than the distance that the tail end of the friction tongue is hidden into the side plate before reversing of a reversing control plate is relieved. Accordingly, after the limitation on a shifting block by the reversing control plate is relieved, and when the touching tongue of the friction tongue swings backwards to lean on the oblique plane of the friction tongue base under the action of a friction tongue spring, the whole friction tongue slides out of a friction tongue slide hole of the side plate, and therefore the reversing of the whole friction tongue assembly can be achieved in a manner than the friction tongue rotates by 180 degrees in the friction tongue slide hole of the side plate when the friction tongue assembly rotates in a bottom plate horizontally. Big reversing notches do not need to be formed in the bottom plate and a cover plate, and the trouble that the side plate needs to be disassembled to achieve reversing is avoided. Therefore, the friction tongue lock body reversing structure is reasonable in structure and can ensure the stress strength and beauty of a lock shell, and the reversing adjustment is convenient.

[specific embodiment]
The present invention is a kind of friction tongue lock body commutating structure, as shown in Figures 1 to 3, include by base plate 11, the lock housing 1 that cover plate 12 and side plate 13 form, and be arranged on the friction tongue assembly 2 in lock housing 1, described friction tongue assembly 2 includes friction tongue bar 21, be arranged on respectively friction tongue bar 21 front in circle friction tongue seat 22 on rear three positions, friction tongue spring (not shown in FIG.) and friction tongue slide block 24, be arranged on upper on friction tongue seat 22, lower two friction tongues 25, and swing is connected to these two the friction tongues shake-up tongues 26 between friction tongue 25, these structures are basically identical with the lock body of the tool friction tongue of present stage, difference is: in lock housing 1, be also provided with commutation control panel 3 and the control panel 3 that makes to commutate is flapped toward the spring 4 of friction tongue slide block 24 all the time, the effect of spring is when using lock body, to make commutation control panel keep off all the time before friction tongue slide block 24, the tongue that prevents from rubbing skids off the friction tongue slide opening of side plate 13 under the spring action of friction tongue, could normally use lock body like this, on the two side of described commutation control panel 3, be equipped with and drop on respectively swing hole 111,121 and the swinging axle 31 in arcuate socket 112,122 of base plate 11 and cover plate 12 and swing slide unit 32, described commutation control panel 3 can keep off in friction tongue slide block 24 the place aheads when being flapped toward friction tongue slide block 24, the diameter of described circular friction tongue seat 22 is less than the vertical width W of the friction tongue slide opening 131 on side plate 13, and we know, the lateral length of friction tongue slide opening 131 is larger than vertical width, and the tongue seat 22 that rubs when commutation like this can rotate in friction tongue slide opening, described friction tongue seat 22 is provided with inclined-plane 221 in the side of touching tongue 26 over against friction tongue, the displacement S that when support that described friction tongue touches tongue 26 is stirred boss 261 and contacted this position with side plate 13 inwalls lean against inclined-plane 221 to swing from lock-out state, the left vertical edge 262 of this boss swings than at this commutation control panel 3, remove commutate before the described friction tongue 25 tail ends distance D of hiding in side plate 13 large, as Fig. 4, shown in 5, so when commutation control panel 3 is removed the locking to friction tongue assembly, under the spring action of friction tongue, whole friction tongue skids off the friction tongue slide opening of side plate, in the time of so just can making whole friction tongue assembly horizontally rotate in base plate, by friction tongue seat, in the friction tongue slide opening of side plate, rotating 180 degree has commutated.
When normal operating condition, friction tongue tail end is hidden in side plate 13, at this moment just cannot rotate whole friction tongue assembly and commutate, as shown in Figure 2,3, and in the time will commutating, two fingers are pinched on the swing slide unit in the arcuate socket of base plate and cover plate, the control panel that makes to commutate is shown friction tongue slide block and is removed after the restriction of slide block, under the spring action of friction tongue, when friction tongue touches on the inclined-plane 221 that leans against friction tongue seat 22 after tongue swings backward, whole friction tongue skids off the friction tongue slide opening 131 of side plate 13, at this moment the tongue seat that rubs is just arranged in the friction tongue slide opening 131 of side plate, because the aperture ratio friction tongue slide opening 131 of friction tongue seat is little in vertical width W, in the time of so just can making whole friction tongue assembly horizontally rotate in base plate, by friction tongue seat 22, in the friction tongue slide opening 131 of side plate 13, rotating 180 degree has commutated.After completing commutation, hand lifts friction tongue 25 a little makes it to quasi-friction tongue slide opening 131 is rear, toward lock housing 1 in, push away, and just can be blocked by control panel, thereby completed commutation when friction tongue slide block 24 slides into after exceeding the control panel 3 that commutates inward.
As can be seen from above, because friction tongue seat 22 is provided with inclined-plane 221 in the side of touching tongue 26 over against friction tongue, and described friction tongue touch the support of tongue 26 stir boss 261 from side plate 13 touch the displacement S that swings the left vertical edge 262 of this boss while leaning against inclined-plane 221 than at this commutation control panel 3, remove commutate before the described friction tongue 25 tail ends depth D of hiding in side plate 13 large, like this after commutation control panel 3 is removed the restriction of slide block, under the spring action of friction tongue, when friction tongue touches on the inclined-plane 221 that leans against friction tongue seat 22 after tongue 26 swings backward, whole friction tongue skids off the friction tongue slide opening of side plate, in the time of so just can making whole friction tongue assembly horizontally rotate in base plate, by friction tongue seat 22, in the friction tongue slide opening 131 of side plate 13, rotating 180 degree has commutated, so the present invention is without offer the breach that commutates greatly on base plate and cover plate, also need not pull down the side plate trouble that commutates so, therefore of the present invention rational in infrastructure, commutate easy to adjust, and can guarantee that lock is subject to force intensity and aesthetic property.
In the present embodiment, as shown in Figure 3, described spring 4 is the torsion springs that are enclosed within on the swinging axle 31 of these commutation control panel 3 bottoms; Described torsion spring one end is resisted against on the upper surface of base plate, and the other end acts on this commutation control panel 3, so that commutation control panel 3 keeps off all the time in friction tongue slide block the place ahead.Certainly, spring 4 can be also stage clip or extension spring, as long as can produce the power that the control panel that makes to commutate is flapped toward the tongue slide block 24 that rubs all the time.
The present invention can be applied on the lock bodies such as theftproof lock, Steel-clad lock, as long as be provided with friction tongue and friction tongue shake-up tongue on the friction tongue assembly of lock body.
Be only preferred embodiment of the present invention in sum, be not used for limiting practical range of the present invention, i.e. all equivalences of doing according to the content of the present patent application the scope of the claims change and modify, and all should belong to technology category of the present invention.
