[0027] (Example 1)

[0028] See Figure 1-3The resilient extended cam lock of this embodiment is disposed within a lock case 1. The lock case 1 has at least one retractable flip surface 1-1 (in this embodiment, the upper cover). The lock case 1 includes a lock cylinder 2 extending through the side wall of the lock case 1, a lock plate connector 4 equipped with a lock plate 3, a lock catch 5 fixed to the lower end surface of the upper cover of the lock case 1, a lock plate torsion spring 6 sleeved on the lock cylinder 2, and a lock plate stop 7 fixed to the side wall of the lock case 1 for supporting the lock plate connector 4 and limiting the rotation of the lock plate 3. The lock cylinder 2 is fixedly connected to the lock plate connector 4, which is disposed on an axial extension of the lock cylinder 2. The lock plate torsion spring 6 provides a rotational force for the lock cylinder 2 in a first direction, causing the lock plate 3 to engage with the lock catch 5 or abut against the lock plate stop 7. When the lock cylinder 2 rotates in a second direction, the lock plate 3 disengages from the lock catch 5. The first direction is opposite to the second direction. The cam lock is made of stainless steel, which enhances structural strength while being resistant to friction, wear, and corrosion. The contact surfaces inside the lock body must be polished to ensure smoothness, and lubricating oil must be applied during assembly to ensure smooth operation of the entire transmission.

[0029] For details, see Figure 1-2 The lock box 1 is rectangular and includes a first side wall 1-2. The upper cover is rotatably connected to the first side wall 1-2. The lock plate stopper 7 is fixed on the side wall opposite to the first side wall 1-2. The first side wall 1-2 is rotatably connected to the upper cover by a hinge, so that the user can open and close the lock box 1 conveniently. The lock cylinder 2 is arranged on the side wall adjacent to the first side wall 1-2. As a preferred solution of this embodiment, the lock cylinder 2 is arranged at an end away from the first side wall 1-2 so that the lock plate 3 is close to the lock plate stopper 7.

[0030] See Figure 2-3 The lock 5 includes a lock fixing seat 5-1 and a locking rod 5-2. The lock fixing seat 5-1 is fixed on the lower end surface of the upper cover of the lock box 1, and the locking rod 5-2 is fixed on the lock fixing seat 5-1; a lock plate groove 3-1 is provided on the lock plate 3, and the locking rod 5-2 cooperates with the lock plate groove 3-1. When the lock rod 5-2 is embedded in the lock plate groove 3-1, the lock box 1 is locked.

[0031] An inclined surface 3-2 is provided on the outer edge of the locking plate groove 3-1 near the upper cover. The angle between the inclined surface 3-2 and the sidewall of the locking plate groove 3-1 is 30°-60°, with a preferred angle of 45° in this embodiment. When the upper cover is closed, the locking rod 5-2 engages the inclined surface 3-2. As the locking rod 5-2 falls, it pushes the locking plate 3 to overcome the rebound force of the locking plate torsion spring 6. When the locking rod 5-2 reaches the locking plate groove 3-1, the locking plate 3 rebounds and locks securely under the action of the locking plate torsion spring 6.

[0032] The lock plate connector 4 includes a first connecting portion 4-1 and a second connecting portion 4-2. The first connecting portion 4-1 is fixedly connected to the lock cylinder 2. The second connecting portion 4-2 passes through a lock plate block 7 and is rotatably connected to the lock plate block 7. The end of the lock plate connector 4 is supported by the lock plate block 7. The lock plate 3 is sleeved and fixed on the second connecting portion 4-2. The lock plate connector 4 is arranged along the axial direction of the lock cylinder 2. The length of the lock plate connector 4 can be customized to suit lock boxes 1 of various sizes. After installation, the lock plate 3 is positioned at the midpoint of the lock box 1, ensuring a secure and reliable connection when the upper cover is closed.

[0033] A baffle 1 - 3 is provided on the side wall of the lock box 1 , and one end of the lock plate torsion spring 6 abuts against the first connecting portion 4 - 1 , and the other end abuts against the baffle 1 - 3 .

[0034] The lock buckle 5 and the lock piece block 7 are both provided with waist-shaped holes to facilitate later installation.

[0035] The present invention operates as follows: When the upper cover of the lock box 1 is closed, the lock catch 5 moves downward with the upper cover. The locking plate 3, which has a 45° inclined surface, automatically retracts inward upon contact with the locking rod 5-2. When the locking rod 5-2 reaches the locking plate notch 3-1, the locking plate 3 rebounds and locks under the action of the locking plate torsion spring 6. To open the upper cover, an external force is applied to turn the key, causing the locking plate 3 to rotate and flip the upper cover upward. When the upper cover is opened, the locking rod 5-2 disengages the locking plate notch 3-1. At this point, the external force is no longer applied, and the locking plate torsion spring 6 constantly exerts a rebound force, limiting the rotation of the locking plate 3 via the locking plate stop 7.

[0036] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
