Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a lock body structure with a ferrule positioning mechanism. Background Technology

[0002] The lock body is the main component of a lock and the core part of a lock used to securely fix it to objects such as doors, windows, and cabinets. It is usually made of metal materials such as steel, iron, and aluminum, and has the functions of locking and unlocking. In daily life, the lock body is an important part of protecting the safety of the home and property.

[0003] Current lock body structures typically use bolts to fix the lock body to the pre-drilled mounting grooves on the door. Since the lock body structure does not have an adjustment function during installation, if the pre-drilled depth of the mounting groove on the door is too deep, the lock body will be recessed into the groove during installation and will not be able to keep flush with the edge of the door, thus adversely affecting the security of subsequent locking. Utility Model Content

[0004] The purpose of this utility model is to provide a lock body structure with a card slot positioning, which allows personnel to easily adjust the lock body according to the depth of the mounting groove during installation, ensuring that the lock body can be flush with the edge of the door and ensuring locking security.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lock body structure with a ferrule positioning, comprising a mounting plate, a positioning ferrule fixedly connected to the right side of the mounting plate, a lock body body slidably connected between the inner cavity of the positioning ferrule and the middle end of the mounting plate, a pin groove being provided at the left end of both sides of the lock body body, a receiving hole being provided at the middle end of both sides of the positioning ferrule, a pin being slidably connected between the surface of the receiving hole and the surface of the pin groove, a fixing frame being slidably connected to the upper end of the outer surface of the positioning ferrule, and a stop block being fixedly connected to both ends of the bottom of the fixing frame, the surface of the stop block being slidably connected to the surface of the pin.

[0006] As a preferred embodiment, slots are provided at the upper ends of both sides of the outer surface of the positioning sleeve, metal springs are fixedly connected to both sides of the fixing frame, and a locking block is fixedly connected to the lower end of the metal spring.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0022] Please see Figures 1-4 As shown, this utility model provides a lock body structure with a ferrule positioning, including a mounting plate 3, a positioning ferrule 2 fixedly connected to the right side of the mounting plate 3, a lock body 1 slidably connected between the inner cavity of the positioning ferrule 2 and the middle end of the mounting plate 3, a pin groove 16 is provided at the left end of both sides of the lock body 1, a receiving hole 14 is provided at the middle end of both sides of the positioning ferrule 2, a pin 15 is slidably connected between the surface of the receiving hole 14 and the surface of the pin groove 16, a fixing frame 8 is slidably connected to the upper end of the outer surface of the positioning ferrule 2, and a stop block 10 is fixedly connected to both ends of the bottom of the fixing frame 8, and the surface of the stop block 10 is slidably connected to the surface of the pin 15.

[0023] In this technical solution, the installation of the liner plate 3 and the positioning sleeve 2 provides support and positioning for the lock body 1 during installation. The inclusion hole 14, pin 15, and pin groove 16 limit the movement between the lock body 1 and the positioning sleeve 2, preventing displacement and shaking of the lock body 1 during use. The fixing frame 8 and the stop block 10 limit one side of the pin 15, preventing it from displacing from the surface of the pin groove 16. Through the combined action of these components, the lock body 1 can be effectively adjusted during installation, preventing it from being unable to remain flush with the edge of the door due to the depth of the installation groove. This ensures the security of the lock body 1 when it is locked. Example

[0024] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the upper ends of both sides of the outer surface of the positioning sleeve 2 are provided with slots 13. Metal springs 7 are fixedly connected to both sides of the fixing frame 8. The lower end of the metal springs 7 is fixedly connected with a block 11. The surface of the block 11 is slidably connected to the surface of the slot 13. Limiting strips 12 are fixedly connected to the upper ends of both sides of the outer surface of the positioning sleeve 2. There are four limiting strips 12. The surface of the fixing frame 8 is slidably connected to the surface of the limiting strips 12. The surface of the block 10 is fixedly connected with a reinforcing rib 17. The top of the reinforcing rib 17 is fixedly connected to the bottom of the fixing frame 8. The fixing frame 8 is U-shaped. The top of the outer surface of the positioning sleeve 2 is provided with a groove 9. The two ends of the mounting plate 3 are provided with mounting holes 5. Mounting bolts 4 are inserted into the surface of the mounting holes 5. A rubber pad 6 is pasted on the right side of the mounting plate 3. The two ends of the rubber pad 6 are provided with through holes.

[0025] In this technical solution, the arrangement of the slot 13, the metal spring 11, and the locking block 7 allows the locking block 7 to be inserted into the surface of the slot 13 under the action of the metal spring 11. This creates resistance between the fixed frame 8 and the positioning sleeve 2, preventing the fixed frame 8 from coming loose from the surface of the positioning sleeve 2 during non-human operation. The setting of the limiting stop 12 limits the movement between the fixed frame 8 and the positioning sleeve 2, preventing the fixed frame 8 from shifting along the surface of the positioning sleeve 2. The setting of the reinforcing rib 17 effectively improves the connection strength between the stop 10 and the fixed frame 8. The setting of the groove 9 facilitates the use of a flathead screwdriver to pry the fixed frame 8. The setting of the mounting hole 5 and the mounting bolt 4 facilitates the installation of the entire assembly with the mounting groove of the door body. The setting of the rubber pad 6 effectively improves the contact effect between the mounting liner 3 and the door mounting groove during installation.

[0026] The working principle of this utility model is as follows: During the installation of the lock body 1, due to the influence of the depth of the mounting groove on the door, the edge of the lock body 1 located on the latch side cannot be aligned with the edge of the door. By using a flathead screwdriver to pry the upper end of the fixing frame 8, the fixing frame 8 can move upward along the surface of the positioning sleeve 2 under the action of force. The movement of the fixing frame 8 can drive the stop block 10 to move, causing the stop block 10 to disengage from the surface of the pin 15, thereby releasing the limit on one side of the pin 15. Subsequently, by pushing the lock body 1 to the left along the surface of the positioning sleeve 2 and the mounting liner 3, the movement of the lock body 1 can drive the pin groove 16 to move, allowing the pin 15 to move along the surface of the pin groove 16 and the receiving hole 14, while protruding to the fixed position. When the side of the positioning sleeve 2 is aligned with the edge of the lock body 1, the stop block 10 can be moved by pushing the fixing frame 8 downwards. The stop block 10 can contact the arc surface of the protruding pin 15 on the side of the positioning sleeve 2, and push the pin 15 along the arc surface along the surface of the receiving hole 14. This allows the pin 15 to be inserted into different positions of the pin groove 16 (it should be noted that the pin groove 16 is composed of multiple hemispherical grooves), which can lock and limit the lock body 1 again. This achieves the effect of effectively adjusting the lock body 1 during installation, avoiding the lock body 1 from not being able to keep flush with the edge of the door due to the depth of the installation groove, thus ensuring the security of the lock body 1 when locking.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
