Abstract
The utility model relates to a lock body accessory provides roll spring bolt subassembly amortization mechanism. If a lock box subassembly, a roll spring bolt subassembly and an adjusting part. In lock box subassembly is located to roll spring bolt subassembly, fix the ball on the ball fixing base through the round pin axle, and in wearing to locate lock tongue hole with the ball, wear to establish reset spring, fixed set, two O type circles of rubber ring, gasket on the pull rod in proper order to put into damping fat at the fixed cover of rubber ring, arrange the holding ring on the pull rod in on the ball fixing base draw -in groove at last, arrange the other end of pull rod in on the pull rod mount sliding tray in, and solid in the constant head tank with the fixed locating piece of sheatheeing in of rubber ring. Roll spring bolt subassembly when motion, thus the ball of spring bolt part can around the round pin rotation of axes avoided with the direct impact of door frame, the O type circle of parcel and the frictional resistance of damping fat also play the cushioning effect in the fixed cover of the rubber ring on the pull rod in addition, impel roll spring bolt subassembly translation rate to reduce, so have reduced the collision noise.
Description
Technical field
The utility model relates to a kind of five metals door lock fittings, especially the spring bolt parts of door lock.
Background technology
Door lock adopted in the market, in enabling and at closing time, because of lock body inner body between collision and friction and dead bolt and doorframe collide and all can sound, along with the raising of the hierarchy of consumption of people, in office space or residential applications, all wish to reduce this type of noise as far as possible.Clash into sound to reduce this type of, CN103899145A discloses a kind of mode arranging damper in dead bolt rear end to the scheme of the speed slowing down dead bolt and eject, and can slow down the friction of bolt component and lock body inside; For slowing down the shock between dead bolt and doorframe, usually adopting at present and dead bolt is set as trident tongue.But it is not scheme disclosed in CN103899145A need coordinate special damper rod, complex structure, good with the suitability of standard lockset; Still can produce sliding friction between trident tongue and doorframe, still can produce metal friction noise.
Summary of the invention
The purpose of this utility model solves the dead bolt of door lock and doorframe collides and inner bolt component collides and the rubs noise problem produced, and provides a kind of rolling bolt component silencer mechanism.
The technical solution adopted in the utility model is: establish a lock box assembly, a rolling bolt component and an adjusting part; Liner plate on front side of described lock box assembly is provided with dead bolt hole, and lock box component bottom is provided with pull bar fixed mount, in the middle part of pull bar fixed mount, is provided with sliding tray, on the left of pull bar fixed mount, be provided with locating slot; Described rolling bolt component comprises a bearing pin, a ball, a ball holder, a pull bar, a cushion rubber fixed cover, two O type circles, damping grease, a pad, a back-moving spring, a spring, adjustment screw, described ball is provided with through hole A, described ball holder is provided with through hole B, screw and draw-in groove, described pull bar is provided with locating ring, and described cushion rubber fixed cover is provided with locating piece.The assembly relation of each component: bearing pin is arranged in through hole A and ball is fixed on ball holder by through hole B, and is arranged in dead bolt hole by ball; Regulating spring is through in adjustment screw, adjustment screw is fixed in the screw of ball holder; Pull bar wears successively back-moving spring, cushion rubber fixed cover, two O type circles, pads, and put into damping grease at cushion rubber fixed cover; Locating ring on pull bar is placed in the draw-in groove on ball holder, the other end of pull bar is placed in the sliding tray on pull bar fixed mount, and the locating piece on cushion rubber fixed cover is fixed in the locating slot of lock box assembly.
The utility model beneficial effect is: free state at closing time, directly push or pull handle, start to rotate after ball and door frame contact and move backward, thus translation after promoting whole rolling bolt component, in cushion rubber fixed cover on pull bar, the O type circle of parcel and the frictional resistance of damping grease also play cushioning effect, impel rolling bolt component translational speed to reduce, therefore reduce noise when colliding between part, and O type circle also plays the effect of sealing damping grease; Because the ball of dead bolt part can rotate around lock pin thus avoid the direct collision with doorframe, therefore more further decrease noise during collision.When external force is removed, rolling bolt component is shifted forward under the active force of back-moving spring, the type circle wrapped up in cushion rubber fixed cover on pull bar and damping grease start to play frictional resistance effect, impel rolling bolt component translational speed to reduce, therefore reduce noise when colliding between part.
By turning adjusting screw, stretching out highly of adjustable ball holder, thus make the crack between a door and its frame of the applicable different in width of described ball.

Detailed description of the invention
The utility model is by such as under type enforcement:
As shown in Figure 1, if lock box assembly 1, rolling bolt component 2 and an adjusting part 3; Liner plate 11 on front side of described lock box assembly 1 is provided with dead bolt hole 111, is provided with pull bar fixed mount 12, in the middle part of pull bar fixed mount 12, is provided with sliding tray 121, be provided with locating slot 13 on the left of pull bar fixed mount 12 bottom lock box assembly 1; Described rolling bolt component 2 comprises bearing pin 21, ball 22, ball holder 23, pull bar 24, cushion rubber fixed cover 25, two O type circles 26, damping grease 27, pad 28, back-moving spring 29; Described adjusting part 3 comprises regulating spring 31, adjustment screw 32; Described ball 22 is provided with through hole A221, and described ball holder 23 is provided with through hole B231, screw 232 and draw-in groove 233, and described pull bar is provided with locating ring 241, and described cushion rubber fixed cover 25 is provided with locating piece 251.The assembly relation of each component: be arranged in through hole A221 and through hole B231 by bearing pin 21 and ball 22 is fixed on ball holder 23, regulating spring 31 is through in adjustment screw 32, adjustment screw 31 is fixed in the screw 232 of ball holder 23, this part is placed in lock box assembly 1, and ball 22 is arranged in dead bolt hole 111; Pull bar 24 wears successively back-moving spring 29, cushion rubber fixed cover 25, two O type circles 26, pads 28, and put into damping grease 27 in cushion rubber fixed cover 25; Finally the locating ring 241 on pull bar 24 is placed in the draw-in groove 233 on ball holder 23, the other end of pull bar 24 is placed in the sliding tray 121 on pull bar fixed mount 12, and the locating piece 251 on cushion rubber fixed cover 25 is fixed in the locating slot 13 of lock box assembly 1.
As shown in Figure 2 and Figure 3: free state at closing time, directly push or pull handle, start to rotate after ball 22 and door frame contact and also move backward, thus translation after promoting whole rolling bolt component 2, in cushion rubber fixed cover 25 on pull bar 24, the O type circle 26 of parcel and the frictional resistance of damping grease 27 play cushioning effect, impel rolling bolt component 2 translational speed to reduce, therefore decrease the collision noise between part, and O type circle 26 also plays the effect of sealing damping grease 27; Because the ball 22 of dead bolt part can rotate around bearing pin 21 thus avoid the direct collision with doorframe, therefore more further decrease collision noise.When external force is removed, rolling bolt component 2 shifted forward under the active force of back-moving spring 29, in cushion rubber fixed cover 25 on pull bar 24, the O type circle 26 of parcel and the frictional resistance of damping grease 27 also play cushioning effect, impel rolling bolt component 2 translational speed to reduce, therefore also can reduce the collision noise between part.By turning adjusting screw 32, stretching out highly of adjustable ball holder 23, thus make the crack between a door and its frame of the applicable different in width of described ball 22.
