Description

Technical Field

[0001] This utility model belongs to the field of door lock technology, and specifically relates to a positioning structure for door lock handles. Background Technology

[0002] Chinese Patent CN221031944U discloses an anti-accidental touch door handle, including a door lock body, a handle body on one side of the door lock body, and a limiting component on the outside of the handle body on one side of the door lock body. The limiting component includes a fixed sleeve fixedly installed on one side of the door lock body, and the handle body is rotatably connected to the fixed sleeve. A housing is fixedly installed inside the fixed sleeve. A fixed seat is fixedly installed on one side of the fixed sleeve. A limiting rod is slidably connected between the fixed seat and the inside of the fixed sleeve. A limiting groove is opened on one side of the handle body, and the limiting groove is engaged with the limiting rod. A return spring is sleeved on the outer side of the limiting rod.

[0003] The above technical solution has the following drawbacks: When a person opens the door lock body, the insertion rod must first be released from its limit position. The finger presses the pressing block, causing the pressing block to move the sliding block, which in turn causes the moving rod to slide in the sliding groove. After the moving rod moves, it causes the rotating rod to rotate. While the rotating rod rotates, one end is hinged to the moving rod and the other end is hinged to the limit rod. The moving rod is limited to sliding outside the housing by the sliding block to prevent it from moving to the right. Then, the rotating rod rotates, causing the limit rod to move on the fixed seat. After the limit rod moves, the fixed block can stretch the return spring, which can disengage the limit rod from the limit groove on the handle body, allowing the handle body to be released from its limit position and rotated. When the handle body is reset, the pressing block is released and the limit rod is reset under the action of the return spring, so that the limit rod and the limit groove engage to limit the handle body and prevent accidental rotation of the handle body. Although this handle has an anti-accidental-touch function, the operation steps are cumbersome and affect the convenience of use. Utility Model Content

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] A door lock handle uses a positioning structure, such as Figures 1 to 5 As shown, the device includes a door lock body 1 and a handle body 2. The handle body 2 is rotatably mounted on the door lock body 1. The door lock body 1 is provided with a connection hole 17. The handle body 2 is rotatably mounted in the connection hole 17 and cannot be disengaged from the connection hole 17. The handle body 2 can move along the axial direction of the connection hole 17.

[0020] Specifically, an annular connecting piece 18 is installed at the bottom of the handle body 2, and an annular connecting piece 29 is installed on the annular connecting piece 18. The annular connecting piece 18 is movably inserted through the connecting hole 17. An annular groove 20 is formed between the annular connecting piece 29 and the bottom of the handle body 2. The door lock body 1 includes a liner 21. The connecting hole 17 is set on the liner 21. The liner 21 extends into the annular groove 20. A wave washer 22 is sleeved on the outer side of the annular connecting piece 18. The wave washer 22 is located between the liner 21 and the annular connecting piece 29. Through the elastic support of the wave washer 22, the handle body 2 can rotate stably and make a slight displacement along the axial direction of the connecting hole 17.

[0021] The liner 21 extends into the annular groove 20 formed by the annular connecting piece 29 and the bottom of the handle body 2, and the wave washer 22 is located between the liner 21 and the annular connecting piece 29. Therefore, the liner 21 can effectively block the wave washer 22 and the annular connecting piece 29 from passing through the connecting hole 17, thereby preventing the handle body 2 from being completely separated from the door lock body 1.

[0022] The handle body 2 has a panel 3, and the lower surface of the panel 3 has a positioning groove 4. The door lock body 1 has a receiving groove 5, a positioning ball 6 is slidably disposed in the receiving groove 5, and a spring 7 is disposed in the receiving groove 5. The spring 7 is connected to the positioning ball 6, and the positioning groove 4 is adapted to the positioning ball 6.

[0023] When the handle body 2 is rotated so that the positioning groove 4 is aligned with the receiving groove 5, the positioning ball 6 partially enters the positioning groove 4 under the elastic force of the spring 7 to position the handle body 2. At this time, the positioning ball 6 is restricted by the receiving groove 5 and the positioning groove 4, so that the handle body 2 and the door lock body 1 remain relatively stable, thereby locking the handle body 2 and preventing the handle body 2 from being accidentally rotated.

[0024] When the handle body 2 is rotated to completely misalign the positioning groove 4 with the receiving groove 5, the positioning ball 6 disengages from the positioning groove 4. It should be noted that only by applying a greater external force to rotate the handle body 2 can the positioning ball 6 be disengaged from the positioning groove 4, thereby releasing the lock of the handle body 2. In other words, when the user needs to release the lock of the handle body 2, he / she only needs to apply a greater external force to rotate the handle body 2. The operation is simple and convenient.

[0025] Furthermore, a latch 8 is installed on the door lock body 1. When the positioning ball 6 partially enters the positioning groove 4 to position the handle body 2, the latch 8 presses against the upper surface of the panel 3. Specifically, one side of the latch 8 has a notch 9. Rotating the handle body 2 can drive the panel 3 into the notch 9, so that the upper surface of the panel 3 abuts against the bottom of the notch 9.

[0026] When the upper surface of panel 3 abuts against the bottom of notch 9, the positioning ball 6 is always located in positioning groove 4 under the elastic force of spring 7. At this time, buckle 8 and positioning ball 6 cooperate to clamp panel 3, thereby further ensuring the static stability of handle body 2 and further locking handle body 2 to prevent handle body 2 from being accidentally rotated.

[0027] The door lock body 1 is provided with an installation groove 10, and the buckle 8 is located in the installation groove 10. The inner side wall of the installation groove 10 is close to the outer side wall of the buckle 8. The buckle 8 is positioned by the installation groove 10, which not only makes it easy to determine the installation position of the buckle 8, but also effectively ensures the stability of the buckle 8.

[0028] A mounting plate 11 is detachably connected to the door lock body 1. The mounting plate 11 is detachably connected to the buckle 8. Specifically, the buckle 8 is pressed on the mounting plate 11. The door lock body 1, the mounting plate 11 and the buckle 8 are connected by bolts 12. The bolts 12 pass through the liner 20 of the door lock body 1 and the mounting plate 11 and are threadedly connected to the buckle 8. This ensures a stable connection between the door lock body 1, the mounting plate 11 and the buckle 8, and also facilitates disassembly and maintenance.

[0029] The mounting plate 11 has a mounting hole 13, and a receiving body 14 with a receiving groove 5 is detachably installed in the mounting hole 13. It should be noted that the positioning ball 6 is prone to wear due to long-term friction with the inner wall of the receiving groove 5, which will affect the positioning accuracy and stability of the positioning ball 6. Therefore, it needs to be maintained and replaced regularly. In this embodiment, the receiving body 14 is inserted and removed into the mounting hole 13, which makes it more convenient to disassemble and maintain the receiving body 14. As another option, the receiving body 14 is threaded to the mounting hole 13.

[0030] The inner wall of the mounting hole 13 is provided with an annular flange 15, and the outer wall of the receiving body 14 is provided with an annular flange 16. When the receiving body 14 is inserted into the mounting hole 13, the upper surface of the annular flange 15 abuts against the lower surface of the annular flange 16. Through the abutting action of the two, the installation position of the receiving body 14 is stabilized, thereby effectively improving the installation efficiency of the receiving body 14.

[0031] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
