Description

Technical Field

[0001] The utility model relates to a door lock oblique bolt reversing mechanism. Background Art

[0002] In actual building environments, there are many situations for the opening and closing directions of doors. For example, some doors open to the left, and some doors open to the right. If the direction of the oblique tongue cannot be changed, it cannot be installed and used normally. Taking the common single-tongue door lock as an example, when the opening and closing direction of the door changes, the oblique tongue needs to be reversed accordingly, so as to ensure that when the door is closed, the oblique tongue can be accurately inserted into the lock hole on the door frame to achieve normal locking function. There are many existing oblique tongue reversing structures, including block-type reversing, bracket spring-type reversing, guide plate reset reversing, manual disassembly reversing, and screw adjustment reversing. These structures are relatively cumbersome as a whole, inconvenient to operate, and affect the reversing efficiency. At the same time, it is difficult for ordinary users to master it, which is not conducive to improving the user's independent installation of the lock body and affects the user experience. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a door lock inclined tongue reversing mechanism, which has a simple structure, a reasonable layout, convenient and efficient inclined tongue reversing operation, and good use effect.

[0004] To achieve the above-mentioned purpose, the utility model provides a door lock inclined bolt reversing mechanism, including a lock body, a lock tongue being retractably arranged in the lock body, the lock tongue comprising an inclined bolt and a connecting rod, a mounting bracket being arranged in the lock body, the connecting rod and the mounting bracket being slidably matched, a resistance spring for keeping the inclined bolt outside the lock body being in contact with each other, the resistance spring being sleeved on the connecting rod, the connecting rod being provided with a first limiting flange for limiting the connecting rod from escaping from the mounting bracket, the inclined bolt being rotatably connected to the connecting rod, the lock body being also rotatably provided with an operating rod, the operating rod being arranged on one side of the connecting rod, the operating rod being matched with a swing arm for being clamped between the first limiting flange and the mounting bracket to make the inclined bolt partially inserted into the lock body, and a traction spring for resetting the operating rod to keep the swing arm between the first limiting flange and the mounting bracket is also connected between the lock body and the swing arm.

[0005] The beneficial effect of such arrangement is that, in such arrangement, the base of the inclined bolt is set as a square bottom, and the lock hole of the lock body is also set as a square hole. When the square bottom is in the lock hole, it has the effect of limiting the rotation of the inclined bolt. When the inclined bolt needs to be reversed, the operating lever is rotated by operating the operating lever so that the swing arm on the operating lever is separated from the position between the first limiting flange and the mounting frame, so that a gap is generated between the first limiting flange and the mounting frame, so that under the action of the resistance spring, the inclined bolt is pushed out a short distance, and at this time the inclined bolt structure is completely separated from the door body, that is, the base of the inclined bolt is no longer restricted by the lock hole, so that the user can operate the inclined bolt to rotate and complete the reversing action of the inclined bolt. This operation is simple and can be completed by ordinary people, with good use experience. After the reversing is completed, the operation of the operating lever is released, and the operating lever is reset under the action of the traction spring, and the swing arm is inserted between the first limiting flange and the mounting frame, so that the inclined bolt is partially immersed in the lock body, and the reversing action of the lock bolt can no longer be performed. This structure is simple, easy to operate, and the overall layout is reasonable, with good use effect.

[0006] As a further configuration of the utility model, the mounting frame includes a first sub-frame body and a second sub-frame body, the connecting rod passes through the first sub-frame body and the second sub-frame body, the traction spring is abutted between the first sub-frame body and the inclined tongue, and the swing arm is arranged between the second sub-frame body and the first limiting flange.

[0007] The beneficial effect of such a setting is that such a setting has a significant effect on improving the stability of the connecting rod position, the overall installation convenience and the connection reliability. The connecting rod passes through the two sub-frames in turn, forming a stable support system in structure, effectively limiting the shaking and displacement of the connecting rod, and greatly enhancing its position stability. At the same time, the traction spring is in contact between the first sub-frame and the inclined tongue, and the swing arm is arranged between the second sub-frame and the first limiting flange. This layout not only optimizes the force distribution of each component, but also enables each component to quickly find the correct position and cooperate closely during the installation process, which greatly simplifies the installation steps, ensures the firmness and reliability of the connection, and lays a solid foundation for the stable operation of the entire device.

[0008] As a further configuration of the utility model, the connecting rod is split into a main rod and a branch rod, one end of the main rod passes through the first branch frame body and the second branch frame body and is rotatably connected with the inclined tongue, and the other end is threadedly engaged with the branch rod, and the first limiting flange is arranged on the branch rod.

[0009] The beneficial effect of such a setting is that, in such a setting, the connecting rod is designed to be composed of a main rod and a branch rod, the main rod can first pass through the first branch frame body and the second branch frame body to complete the rotational connection with the oblique tongue, and then the overall assembly is realized through the threaded cooperation of the branch rod and the main rod. In addition, the first limiting flange is set on the branch rod, which can play a positioning and limiting role during the installation process, effectively avoiding the situation of position deviation or excessive displacement during the installation of the connecting rod, making the entire installation process simpler and more efficient, and even in the relatively narrow internal space of the lock body, the connecting rod can be easily and accurately installed, ensuring assembly efficiency and subsequent use.

[0010] As a further configuration of the utility model, one end of the operating rod is arranged through the lock body, and the other end is arranged through the second sub-frame body, and a second limiting flange is arranged on the end of the operating rod passing through the second sub-frame body.

[0011] The beneficial effect of this arrangement is that the second limiting flange effectively prevents the operating rod from axial displacement during use, ensuring that it is always in a precise working position, thereby ensuring the reliability and stability of the lock operation. At the same time, this layout allows the various components to be closely combined, reduces unnecessary space occupation, makes the entire lock structure more compact, and has good use effect and reliability.

[0012] As a further configuration of the utility model, a matching groove for cooperating with a screwdriver to operate the operating rod to rotate is provided on one end of the operating rod passing through the lock body.

[0013] The beneficial effect of such a setting is that when the lock tongue needs to be operated, the matching groove plays a key role. This design greatly facilitates the user, especially in the absence of special tools, an ordinary screwdriver can be easily inserted into the matching groove, and with the help of the screwdriver as the force point, the user can turn the operating lever conveniently and labor-savingly to realize the rotation control of the operating lever, which effectively improves the convenience and efficiency of operation, reduces the dependence on special tools, and makes the use of the operating lever structure more flexible and practical.
