Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

A handle structure, reducible because of the long-term rotatory handle 2 leads to appearing the wearing and tearing phenomenon.

As shown in fig. 1-2, the panel with the wear-resistant handle 2 in the embodiment includes a casing 1, a through hole 11 is formed in the casing 1, a first shaft sleeve 3 is sleeved outside the through hole 11, and a second shaft sleeve 4 is also sleeved inside the through hole 11.

The front of casing 1 is equipped with handle 2, handle 2 is including holding end 21 and link 22, hold end 21 with link 22 mutually perpendicular, link 22 toward through-hole 11 place direction extends and with first axle sleeve 3 links to each other, makes handle 2 can rotate relatively casing 1.

Slewing mechanism is located the back of casing 1, slewing mechanism includes clutch dial 7, separation and reunion knob 9 and driving piece 10, clutch dial 7 one side toward 1 direction of casing is extended there is spliced pole 71, spliced pole 71 with second shaft sleeve 4 links to each other, makes clutch dial 7 can be relative casing 1 rotates.

And the connecting end 22 of the handle 2 is connected with the connecting column 71 of the clutch turntable 7 through a bolt, so that the clutch turntable 7 and the handle 2 can synchronously rotate.

First axle sleeve 3 with second axle sleeve 4 all establishes to wear-resisting plastics material, just first axle sleeve 3 with the surface of second axle sleeve 4 all is equipped with metal material's wear pad 5, makes handle 2 with it has wear pad 5 to fill between the casing 1 openly, and clutch disc 7 with also fill between the casing 1 back has wear pad 5, makes handle 2 with when clutch disc 7 rotates, can avoid handle 2 slewing mechanism with 1 direct friction of casing increases will when wear pad 5 the axle sleeve establishes to wear-resisting plastics material, can further improve the life of handle.

Meanwhile, an opening is formed in the axis position of the clutch turntable 7, and the clutch knob 9 is limited in the opening, so that the clutch turntable 7 is sleeved outside the clutch knob 9; an opening penetrating through the clutch turntable 7 is formed in the side edge of the clutch turntable 7, a clutch pin 8 is arranged in the opening, one end of the clutch pin 8 is exposed out of the clutch turntable 7, and the other end of the clutch pin 8 penetrates through the clutch turntable 7; a clamping interface 91 is arranged at the position of the clutch knob 9 opposite to the clutch pin 8; meanwhile, a driving piece 10 is arranged outside the clutch turntable 7 and opposite to the clutch pin 8, when the driving piece 10 is triggered, one surface of the driving piece 10 is ejected and abuts against the clutch pin 8, and the clutch pin 8 is pushed into the clamping opening 91, so that the clutch knob 9 and the clutch turntable 7 are clamped with each other.

A lock hole 92 is formed in the axis position of the clutch knob 9, a square rod (not shown) is inserted into the lock hole 92, and the square rod is linked with a bolt mechanism in the lock body; separation and reunion knob 9 with the back is connected to separation and reunion carousel 7 each other, pushes down when the user during handle 2, handle 2 drives separation and reunion carousel 7 separation and reunion knob 9 with the square bar synchronous rotation triggers the spring bolt mechanism withdraws the spring bolt of lock body, realizes unblanking and opens the door the action. The latch mechanism is a linkage component that can drive the latch bolt and the latch bolt to retract or eject in the lock body, and is disclosed in the prior art, so that the detailed description thereof is omitted here.

In the present embodiment, the end of the driving element 10 abutting against the clutch pin 8 is an arc surface 101, and the arc shape of the arc surface 101 is the same as the outer contour shape of the clutch disk 7; and the length of the cambered surface part 101 of the driving piece 10 corresponds to the rotation range of the clutch dial 7, so that the cambered surface part 101 always compresses the clutch pin 8 after the driving piece 10 is triggered, and the state that the clutch dial 7 is clamped with the clutch knob 9 is maintained. When the driving piece 10 is triggered, the cambered surface part 101 pops up and supports the clutch pin 8, so that the clutch pin 8 is pushed into the clamping interface 91 to complete the clamping action of the clutch knob 7 and the clutch turntable 9, and the clutch knob 7 and the clutch turntable 9 can synchronously rotate.

At least two stoppers 12 are arranged on the back of the shell 1 and outside the through hole 11, torsion springs 6 are sleeved outside the stoppers 12, and the connecting columns 71 of the clutch turnplate 7 penetrate through the torsion springs 6, so that the operation of the clutch turnplate 7 is not affected by the installation of the torsion springs 6. Two clamping blocks (not marked in the figure) are arranged on the side edge of the clutch knob 9, wherein one clamping block is abutted with one torsion bar of the torsion spring 6, and the other clamping block is abutted with the other torsion bar of the torsion spring 6; when a user presses the handle 2 to drive the clutch turntable 7 to rotate, the fixture block abuts against the torsion bar to enable the torsion spring 6 to generate elastic deformation; when the user loosens handle 2, the torsional spring 6 resumes the in-process of deformation can with separation and reunion knob 9 gyrates initial condition, thereby realizes handle 2 and spring bolt resilience effect.

In addition, in order to enhance the function of unlocking the lock body by the anti-knocking technology, as shown in fig. 2, the clutch pin 8 is set to be an inclined structure, that is, a certain included angle is formed between the clutch pin 8 and an axis a line passing through the axis of the clutch turntable 7, and the clutch pin 8 and the driving member 10 are inclined to the same direction by the same angle, so that the lock body can achieve the effect of unlocking the lock body by the anti-knocking technology; in the present embodiment, the inclination angle of the clutch pin 8 and the driving member 10 is 25 °, so that the unlocking effect of the anti-knocking technique can be ensured, and the width of the housing 1 can be prevented from being excessively increased.

In this embodiment, the driving member 10 is triggered by an identification module installed on the housing 1 or the handle 2, and the identification module may be provided with a fingerprint module or a password input module; work as when identification module is fingerprint module, can install fingerprint module on handle 2, fingerprint module's wire can pass in the sleeve cavity and extend to link to each other with control circuit in the casing 1, as shown in fig. 3, avoided the wire along with handle 2 rotatory and the metal friction causes impaired problem.

After the user successfully verifies the identity on the identification module, the identification module can send a trigger signal and send the trigger signal to the driving piece 10, and the driving piece 10 is started after receiving the trigger signal and pops up the cambered surface part 101, so that the clutch pin 8 is supported and pushed into the clamping interface 91, and the clutch knob 9 is clamped with the clutch turntable 7; at the moment, the user presses the handle 2, the clutch rotary disc 7 rotates to drive the clutch knob 9 to synchronously rotate, so that the lock tongue and the square tongue in the lock body are both retracted into the lock body, and the unlocking and door opening actions are realized.

In addition, when the handle 2 rotates, the wear-resistant gasket 5 can prevent the handle 2 and the clutch turntable 7 from directly rubbing against the shell 1, so that the service life of the handle can be prolonged; meanwhile, the rotating mechanism and the handle 2 are axially fixed through the two shaft sleeves inside and outside the through hole 11, so that good axial property can be guaranteed in a long-term use process.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
