Technical Field

[0001] A lock cylinder, especially one used in a lock. Background Art

[0002] General gourd lock core, such as the "anti-destruction gourd lock core improved structure" disclosed in China Publication No. CN204804477U Figure 3 As shown, the application is characterized in that the lock core body is provided with a notch and a lock core through hole, the notch is located in the middle of the lock core body and divides the lock core through hole into an inner lock core through hole and a handle through hole; the inner lock core includes an axis body, the axis body has a key slot extending from the outer end surface to the inner axis, and is penetrated into the inner lock core through hole; the sleeve of the lock core cam is sleeved in the middle of the inner lock core rotating shaft, and then is arranged at the notch and locked with a rivet; the inner lock core rotating shaft passes through the sleeve of the lock core cam and the handle through hole and is locked with the handle.

[0003] The inner lock core and the handle of the application rotate together, so when the door is opened from the outside with a key, it takes a lot of effort to rotate the lock core cam and the handle together, and when the door is opened with the handle, it is difficult to apply force because the handle is too small.

[0004] Other gourd lock cylinders on the market are also designed with keyholes on both sides or only one side for the key, and the other side does not have any door opening mechanism. The above two designs require additional costs to install a handle to open the door. Utility Model Content

[0005] In view of the above problems, the purpose of the present utility model is to provide a lock core for a lock, so as to solve the problem that some lock cores in the prior art do not have handles and need to be additionally installed with handles, and some lock cores with handles require greater effort when opening the door.

[0006] To achieve the above purpose, the utility model provides a lock core for a lock, which includes: a body, the body is provided with a first side and a second side, and the body is provided with a first hole, the first hole passes through the first side and the second side of the body, the body is provided with a hollow portion, and the body is provided with a notch.

[0007] A first paddle, the first paddle is arranged in the hollow part of the main body, the first paddle is provided with a second hole, the first paddle is provided with a convex part, and the convex part can be placed in the notch of the main body;

[0008] The second paddle is arranged in the hollow part of the main body, and the second paddle is provided with a connected part, the second paddle is provided with a convex part, the convex part can be placed in the notch of the main body, and the second paddle is provided with a mounting part.

[0009] An unlocking member, which is passed through the first hole, is provided with a lock hole, and is provided with a fixing portion, which is connected to the second hole of the first paddle and fixes the first paddle so that the first paddle can rotate with the unlocking member, and the unlocking member is provided with a connecting portion, which is connected to the connected portion of the second paddle.

[0010] Furthermore, it includes a handle, which is arranged on the mounting portion.

[0011] Furthermore, the first hole is circular.

[0012] Furthermore, the unlocking member is cylindrical.

[0013] The beneficial effects of the utility model are:

[0014] The fixing portion of the unlocking member in the utility model supports and fixes the first paddle, so that the first paddle can rotate together with the unlocking member, and then the connecting portion of the unlocking member is connected and supported with the connected portion of the second paddle, so that the second paddle can rotate on the connecting portion, thereby achieving the effect that the first paddle and the second paddle are not synchronized when the door is opened on the first side or the second side of the body, and when the door is opened with a key and a handle or a knob is placed on the mounting portion, a large force will not be consumed because the handle or the knob needs to be turned together with the key.

[0032] In order to facilitate and briefly understand the other features and advantages of the present invention and the effects achieved by the present invention, the present invention is now described in detail with the accompanying drawings as follows:

[0033] Please refer to Figure 2 , Figure 3 As shown, a lock core for a lock, comprising:

[0034] A body 1 is provided with a first side 11 and a second side 12 , and a first hole 13 is provided on the body 1 . The first hole 13 passes through the first side 11 and the second side 12 of the body 1 . The body 1 is provided with a hollow portion 14 , and a notch 15 is provided on the body 1 .

[0035] The first paddle 2 is disposed in the hollow portion 14 of the body 1 and has a second hole 21. The first paddle 2 has a convex portion 22, which can be placed in the notch 15 of the body 1. Figure 1 shown.

[0036] The second paddle 3 is arranged in the hollow portion 14 of the main body 1, and the second paddle 3 is provided with a connected portion 31, the second paddle 3 is provided with a protrusion 32, and the protrusion 32 can be placed in the notch 15 of the main body 1. The second paddle 3 is provided with a mounting portion 33, and the mounting portion 33 is located at the second side 12 of the main body 1.

[0037] An unlocking member 4 is provided on the first side 11 of the main body 1 through the first hole 13. The unlocking member 4 is provided with a locking hole 41 and a fixing portion 42. The fixing portion 42 is connected to the second hole 21 of the first paddle 2 and fixes the first paddle 2 so that the first paddle 2 can rotate with the unlocking member 4. The unlocking member 4 is provided with a connecting portion 43, which is connected to the connected portion 31 of the second paddle 3.

[0038] Specifically, the second paddle 3 is supported on the unlocking member 4 through the connecting portion 43 and the connected portion 31 , and the second paddle 3 can rotate freely on the connecting portion 43 of the unlocking member 4 .

[0039] Wherein, a handle 5 or a knob may be further included, and the handle 5 or the knob is arranged on the mounting portion 33 .

[0040] The first hole 13 is circular.

[0041] The unlocking member 4 is cylindrical.

[0042] Please refer to Figure 3 , Figure 4 As shown, when the key 6 is inserted into the lock hole 41 and the unlocking member 4 is rotated, the first paddle 2 will rotate together, and the protrusion 22 of the first paddle 2 will rotate out from the notch 15 to push the mechanism in the lock gate to achieve the effect of opening the door, or a handle 5 can be installed on the mounting portion 33 of the second paddle 3, and the handle 5 can be twisted to drive the second paddle 3, and the protrusion 32 of the second paddle 3 will rotate out from the notch 15 to push the mechanism in the lock gate to achieve the effect of opening the door.

[0043] The first paddle 2 is supported and fixed by the fixing portion 42 of the unlocking member 4 of the utility model, so that the first paddle 2 can rotate together with the unlocking member 4, and then the connecting portion 43 of the unlocking member 4 is connected and supported with the connected portion 31 of the second paddle 3, so that the second paddle 3 can rotate on the connecting portion 43, so that the first paddle 2 and the second paddle 3 are not synchronized when the first side 11 or the second side 12 of the body 1 is opened. When the door is opened with the key 6 and the handle 5 or the knob is placed on the mounting portion 33, it does not consume a lot of force because turning the key 6 also requires turning the handle 5 or the knob. Because the mounting portion 33 of the utility model can place the handle 5, it is possible to apply force better when opening the door.

[0044] The above discussion is only a preferred embodiment of the present invention and is not intended to limit the scope of the claims of the present invention; therefore, any equivalent shape, structure or combination changes made without departing from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
