The tongue rod includes a rod body connected to the tongue and a toggle block extending from one end of the rod body. A first stopper and a second stopper are formed on the shifter, and a gap is defined between the two stoppers; the crank includes Rotate the shaft body and the crank arm extending from the peripheral surface of the shaft body. A toggle groove is axially opened on the shaft body. The peripheral surface of the shaft body forms a first plane and a second plane that intersect each other. A pair of pivots protrude axially outward from the position close to the shaft body, and the end of the crank arm forms a tongue; a first shaft hole is opened on the tailstock, and a second shaft hole corresponding to the first shaft hole is opened on the tail plate; the crank The two pivots of the crank are respectively set in the first and second shaft holes, one of the first and second planes of the crank is in elastic contact with the positioning spring, and the toggle block of the tongue is set between the tailstock and the tail plate , and the crank arm extends into the gap.

Compared with the prior art, the utility model has the advantages of simple structure, low cost and convenient use.

【Detailed ways】

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Referring to Figures 1-8, according to an embodiment of the present utility model, a cylindrical deadbolt assembly 100 includes a tailstock 10, a tailgate 20 buckled together with the tailstock 10, and a tailstock 10 and a tailplate that are arranged on The crank 30 between 20, the tongue bar 50 that cooperates with the crank 30 so as to be dialled, the column tongue 60 that is fixedly connected with the tongue bar 50, and the positioning spring 70 that cooperates with the crank 30.

Firstly, the detailed structure of the tongue bar 50 will be introduced. The tongue bar 50 is used to be moved by the crank 30 so as to drive the tongue 60 connected with the tongue bar 50 to move linearly together, so as to realize the locking or unlocking function of the assembly 100 . Referring to FIG. 3 , the tongue rod 50 includes a rod body 51 mechanically connected with the plunger tongue 60 and a toggle block 52 extending from one end of the rod body 51 . A first stop portion 522 and a second stop portion 524 are formed on the toggle block 52 . A gap 526 is defined between the two stops. The toggle block 52 of the tongue bar 50 is accommodated between the tail stock 10 and the tail plate 20 .

Referring to FIG. 4 , the crank 30 includes a rotating shaft body 32 and a crank arm 34 extending from a peripheral surface of the shaft body 32 . A toggle groove 322 is axially formed on the shaft body 32 , such as a cross-shaped toggle groove 322 , and is used to toggle the crank 30 through the toggle piece 40 (refer to FIG. 1 ) inserted into the toggle groove 322 . In addition, the circumferential surface of the shaft body 32 forms a first plane 324 and a second plane 326 intersecting each other. A pair of pivots 342 axially protrude outward from the crank arm 34 near the shaft body 32 . And the end of the crank arm 34 forms a tongue 346 .

Referring to FIGS. 6-7 , the tailstock 10 is provided with a first shaft hole 12 , and the tail plate 20 is provided with a second shaft hole 22 corresponding to the first shaft hole 12 .

The crank 30 is accommodated between the tail stock 10 and the tail plate 20, and the two pivots 342 of the crank 30 are respectively arranged in the first and second shaft holes 12, 22, so that the crank 30 can surround Its pivot 342 turns. One of the first and second planes 324, 326 of the crank 30 is in elastic contact with the positioning spring 70, so as to ensure that the crank 30 is always in a posture where the first or second plane 324, 326 is in contact with the spring 70 .

The toggle block 52 of the tongue lever 50 is also disposed between the tailstock 10 and the tail plate 20 , and the crank arm 34 of the crank 30 extends into the gap 526 . Insert the toggle piece 40 into the toggle slot 322 of the crank 30 . By turning the paddle 40 , the crank 30 is caused to rotate about its pivot 342 , thereby causing the crank arm 34 to oscillate within the gap 526 . When the crank arm 34 moves the first stop portion 522 to the left, it can cause the tongue bar 50 to move linearly to the left, thereby causing the tongue 60 connected to the tongue bar 50 to also move to the left, thereby realizing the opening action of the assembly. On the contrary, when the crank arm 34 moves the second stopper 524 to the right, it can cause the tongue bar 50 to move linearly to the right, thereby causing the column tongue 60 connected with the tongue bar 50 to also move to the right, thereby realizing the locking of the assembly close action. The function of the tongue 346 is: when the tongue bar 50 moves to the left or right to the end point, the tongue 346 cooperates with the first stop part 522 or the second stop part 524 to control the reverse movement of the tongue bar 50 .

Compared with the prior art, the utility model has the advantages of simple structure, low cost and convenient use.
