Description

Technical Field

[0001] This utility model relates to locks, and more particularly to a button-type combination padlock. Background Technology

[0002] Current padlocks typically use keys to open and close. If a user accidentally loses the key, the padlock becomes uncontrollable and unusable. To prevent this, combination padlocks have been developed that use numbers to open and close the lock. Users do not need to use a key to unlock the padlock; they only need to enter the memorized password to achieve the desired effect, thus avoiding the trouble caused by lost keys.

[0003] However, current combination padlocks generally include a lock body, a U-shaped lock bar, and a combination wheel assembly. The limiting end of the lock bar serves as the axle of the combination wheel assembly. A corresponding number of limiting protrusions are machined on the axle at the position corresponding to the combination wheel to restrict the release of the lock bar. In this type of combination padlock, the lock bar and the combination wheel assembly are integrated, making it difficult to assemble the combination wheel assembly onto the lock bar. Moreover, the lock bar itself is quite difficult to manufacture. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a button-type combination padlock.

[0005] The purpose of this utility model is achieved through the following technical solution: a button-type combination padlock, comprising a lock body and a U-shaped locking rod, wherein the lock body is provided with a combination wheel assembly and a button, one end of the button extends from one side of the lock body, the combination wheel assembly includes a wheel axle, one end of the wheel axle is provided with a stop block, the other end of the button abuts against the stop block, the button is provided with a locking rod through hole, the side wall of the locking rod hole is provided with a limiting step, the U-shaped locking rod has a limiting end and a free end, the limiting end passes through the locking rod through hole, and a limiting groove is provided on one side of the limiting end;

[0006] When locked, the limiting step is engaged in the limiting groove, restricting the ejection of the U-shaped locking rod;

[0007] When unlocking, when the correct password is entered into the password wheel assembly, the wheel axle removes the displacement restriction on the button, pushes the button, the limiting step separates from the limiting groove, and the U-shaped locking rod pops up.

[0008] As an improvement of the button-type combination padlock of this utility model, the button has a support arm, the support arm is provided with two push rods, a positioning groove is formed between the two push rods, and the ends of the two push rods are provided with a first abutting inclined surface.

[0009] As an improvement of the button-type combination padlock of this utility model, the abutting block is provided with two second abutting inclined surfaces, and a positioning block is provided between the two second abutting inclined surfaces. The second abutting inclined surfaces are in contact with the first abutting inclined surfaces, and the positioning block is engaged in the positioning groove.

[0010] As an improvement of the button-type combination padlock of this utility model, the button also has a pressing part, which extends out of the outside of the lock body, and the side of the lock body is provided with a through hole corresponding to the position of the pressing part.

[0011] As an improvement of the button-type combination padlock of this utility model, the lock body includes a front lock body and a rear lock body. The front lock body has screw holes in the middle of both the upper and lower ends, and the rear lock body has locking seats in the middle of both the upper and lower ends. When the front lock body covers the rear lock body, the screws pass through the screw holes and are screwed and fixed to the locking seats.

[0012] As an improvement of the button-type combination padlock of this utility model, the upper end of the lock body is provided with a limiting end through hole and a free end through hole. The limiting end passes through the limiting end through hole, and the free end passes through the free end through hole. The free end corresponds vertically to the combination wheel assembly.

[0013] As an improvement of the button-type combination padlock of this utility model, the limiting end of the U-shaped lock rod has a spring mounting part, a lock rod spring is sleeved on the spring mounting part, a lock rod limiting groove is provided on the inner side wall of the lock body, and the spring mounting part extends into the lock rod limiting groove.

[0014] As an improvement of the button-type combination padlock of this utility model, the combination wheel assembly further includes a spring, a code-changing wheel, a combination wheel, a code-changing block, and a code-changing switch. The wheel axle passes through the code-changing wheel, the combination wheel is sleeved on the code-changing wheel, the code-changing block is disposed at the other end of the wheel axle, the spring is sleeved on the wheel axle, and the code-changing switch corresponds to the code-changing block.

[0015] As an improvement of the button-type combination padlock of this utility model, the bottom of the lock body is provided with a code switch extension hole, and one end of the code switch extends out from the code switch extension hole.

[0016] The advantages of this invention are as follows: This invention uses a button to control unlocking. The button has a limiting step to restrict the locking bar from popping up. One end of the locking bar passes through a hole in the locking bar, and the limiting groove on the locking bar cooperates with the limiting step to prevent the locking bar from popping out. To unlock, simply enter the correct password and press the button. This invention separates the locking bar from the combination wheel assembly, using a button to restrict the locking bar, resulting in a simple structure and convenient unlocking.
