Description

Technical Field

[0001] This utility model belongs to the technical field of locks, specifically relating to a push-button lock. Background Technology

[0002] A push-button lock, as an intermediary component that allows for the connection and unlocking of two parts through a simple pressing operation, is often used to lock or unlock control boxes or cabinets with lids. For example, the domestic utility model patent with patent number CN215476986U describes a similar mechanism. When unlocking, pressing the button causes two movable blocks to slide away from each other on a guide rail through the force transmitted by the pressing plate and the round rod. This allows the first locking block to disengage from the second locking block. Pulling the connecting rod then disengages the first locking block from the second rectangular opening, thus opening the packaging box. The movable block can automatically reset via a spring structure located on the side relatively away from the guide rail. However, because the guide rail and spring are located on opposite sides of the movable block, the unbalanced force on both sides can easily cause the movable block to jam on the guide rail, or require multiple presses to unlock. Furthermore, repeatedly pulling the connecting rod is necessary to confirm unlocking, making the operation cumbersome and resulting in a poor user experience. Utility Model Content

[0003] The purpose of this invention is to provide a push-button lock to address the aforementioned problems and solve the issues existing in the prior art.

[0004] This utility model is achieved through the following technical solution: a push-button lock, including a lock body, a bolt, and an unlock button. A first channel for the unlock button to pass through is provided on one side of the lock body, and a second channel for the bolt to pass through is provided at the upper end of the lock body. The lock body contains a locking member for limiting and fixing the bolt and an elastic power supply member. The power supply direction of the elastic power supply member is on the same straight line as the outward extension direction of the second channel. The bolt passes through the second channel and its lower end abuts against the elastic power supply member. A slot is provided on the side wall of the bolt near the elastic power supply member. The locking member includes... The lock includes a locking head for fixing the bolt in conjunction with a slot, a free end that is close to the unlock button, a T-shaped connecting part that connects the locking head and the free end, and a first spring sleeved on the T-shaped connecting part. One end of the unlock button passes through the first channel and abuts against the free end of the locking component. The inner wall of the lock body is provided with a sliding groove that connects to the second channel. The end of the sliding groove near the second channel is provided with a mounting block for fixing the locking component. The side wall of the sliding groove away from the second channel is provided with a mounting groove for assembling the first spring. When the T-shaped connecting part abuts against the mounting block, one end of the locking head extends out of the sliding groove and is exposed in the second channel.

[0005] Furthermore, the elastic energy supply component includes a power storage tank connected to the second channel, a second spring installed at the bottom of the power storage tank, and a push rod installed at the other end of the second spring away from the bottom of the power storage tank.

[0006] Furthermore, the upper end of the energy storage groove is provided with a through hole for the push rod to extend out, the edge of the through hole is provided with a limiting step that extends towards the center, and the lower end of the push rod is provided with a boss that cooperates with the limiting step.

[0007] Furthermore, the latching component is provided in two symmetrical sets. The free end of the latching component is provided with a first guide slope on the side that abuts against the unlock button. The distance between two adjacent first guide slopes gradually decreases along the direction of the unlock button pressing movement.

[0008] Furthermore, the unlock button includes a fixed guide, a pressing cap, and a trigger rod for use with a locking component. The outer surface of the lower end of the trigger rod is provided with an external thread structure, and the inner wall of the center of the pressing cap is provided with an internal thread structure for use with the external thread structure. A reset spring is sleeved on the trigger rod, with one end of the reset spring abutting against the pressing cap and the other end abutting against the fixed guide.

[0009] Furthermore, the upper end of the trigger rod is provided with a second guide slope that cooperates with the first guide slope of the snap-fit ​​component, and the second guide slope is set in the opposite direction to the first guide slope.

[0010] Furthermore, the main view cross-sectional shape of the mounting block is an inverted L-shaped block with the opening facing the second channel direction. The snap-fit ​​head of the snap-fit ​​member is attached to the upper end of the mounting block, the T-shaped connecting part is attached to the side of the mounting block, the free end is attached to the lower end of the mounting block, and the unlocking button is movably mounted on the lower end of the mounting block and abuts against the free end.

[0011] In its normal state, the latch is inserted and fixed in the second channel. The slot on the side of the latch and the head of the latching component cooperate to form a fixed position. The elastic functional component abuts against the lower end of the latch. The head, free end, and T-shaped connecting part of the latching component are semi-enclosed and fitted onto the mounting block in the slide groove. One end of the first spring is fitted onto the T-shaped connecting part, and the other end is installed in the mounting groove. When unlocking is required, pressing the unlock button causes the free end of the latching component to move to the side. As the unlock button moves continuously, the latching component continues to move to both sides. The elastic component compresses and stores energy, and the latching head on the latching component gradually loosens from the latch until the latching head moves completely from the second channel into the slide groove, thus completely disengaging from the latch. Finally, the elastic energy supply component automatically pushes the latch out of the second channel, thereby realizing the unlocking function. The overall structure is compact, the latching component is evenly stressed, it is not easy to get stuck, and it is easy to use. Attached Figure Description

[0022] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0023] like Figures 1-8As shown, this utility model describes a push-button lock, including a lock body 1, a bolt 2, and an unlock button 3. The lock body 1 has a first channel 11 on one side for the unlock button 3 to pass through, and a second channel 12 on the upper end for the bolt 2 to pass through. The lock body 1 contains a locking member 13 for limiting and fixing the bolt 2, and an elastic power supply member 14. The power supply direction of the elastic power supply member 14 is on the same straight line as the outward extension direction of the second channel 12. The bolt 2 passes through the second channel 12 and its lower end abuts against the elastic power supply member 14. A slot 21 is formed on the side wall of the bolt 2 near the elastic power supply member 14. The locking member 13 includes a locking head 131 that cooperates with the slot 21 to fix the bolt 2. The lock body 1 has a free end 132 that is close to the unlock button 3, a T-shaped connecting part 133 that connects the locking head 131 and the free end 132, and a first spring 134 that is sleeved on the T-shaped connecting part 133. One end of the unlock button 3 passes through the first channel 11 and abuts against the free end 132 of the locking member 13. The inner wall of the lock body 1 has a slide groove 15 that connects to the second channel 12. The end of the slide groove 15 near the second channel 12 has a mounting block 151 for locking and fixing the locking member 13. The side wall of the slide groove 15 away from the second channel 12 has a mounting groove 152 for assembling the first spring 134. When the T-shaped connecting part 133 abuts against the mounting block 151, one end of the locking head 131 extends out of the slide groove 15 and is exposed in the second channel 12.

[0024] Under normal conditions, the latch 2 is inserted and fixed in the second channel 12. The slot 21 on the side of the latch 2 cooperates with the head 131 of the latching member 13 to form a fixed position. The elastic functional member abuts against the lower end of the latch 2. The head 131, free end 132, and T-shaped connecting part 13 of the latching member 13 are semi-enclosed and sleeved on the mounting block 151 in the slide groove 15. One end of the first spring 134 is sleeved on the T-shaped connecting part 133, and the other end is installed in the mounting groove 152. When unlocking is required, pressing the unlock button 3 causes the latch to engage. The free end 132 of component 13 moves to the side, thereby unlocking button 3. During the continuous movement, the locking component 13 continues to move to both sides, the elastic element compresses and stores energy, and the locking head 131 on the locking component 13 gradually loosens from the locking tongue 2 until the locking head 131 moves completely from the second channel 12 into the slide groove 15, thereby completely loosening from the locking tongue 2. Finally, the elastic energy supply component 14 automatically pushes the locking tongue 2 out from the second channel 12, thereby realizing the unlocking function. The overall structure is compact, the locking component 13 is evenly stressed, it is not easy to get stuck, and it is easy to use.

[0025] like Figure 3As shown, the elastic energy supply component 14 in this embodiment of the present invention includes a power storage groove 141 connected to the second channel 12, a second spring 142 installed at the bottom of the power storage groove 141, and a push rod 143 installed at the other end of the second spring 142 away from the bottom of the power storage groove 141. When the latch 2 is locked by the latching component 13, the lower end of the latch 2 abuts against the upper end of the push rod 143. The lower end of the push rod 143 applies pressure to the second spring 142 to compress and store energy. Thus, when the latching component 13 releases the locking state of the latch 2, the second spring 142 releases elastic force in the power storage groove 141 to drive the push rod 143 to move. Then, the push rod 143 drives the latch 2 to move upward and push it out of the lock body 1.

[0026] Furthermore, the upper end of the energy storage groove 141 is provided with a through hole 1411 for the push rod 143 to extend out. The edge of the through hole 1411 is provided with a limiting step 1412 extending towards the center. The lower end of the push rod 143 is provided with a boss 1431 that cooperates with the limiting step 1412 to prevent the push rod 143 from dislodging from the energy storage groove 141 due to inertia when the second spring 142 releases its elastic force. This ensures that the push rod 143 and the second spring 142 can always be aligned and guided within the energy storage groove 141 for convenient cyclic use.

[0027] like Figure 4-6 As shown, in this embodiment of the present invention, two sets of snap-fit ​​components 13 are symmetrically arranged. The free end 132 of the snap-fit ​​component 13 is provided with a first guide slope 1321 on the side that abuts against the unlock button 3. The distance between two adjacent first guide slopes 1321 gradually decreases along the direction of the pressing movement of the unlock button 3. Thus, when the unlock button 3 is pressed and moved, the unlock button 3 pushes the snap-fit ​​components 13 on both sides apart through the first guide slope 1321. Since the size of the unlock button 3 itself remains unchanged, the snap-fit ​​components 13 move to both sides of the unlock button 3, which is equivalent to the unlock button 3 squeezing between two adjacent snap-fit ​​components 13. While the snap-fit ​​component 13 is moving, the elastic component compresses and stores energy, and the snap-fit ​​state between the snap-fit ​​head 131 on the snap-fit ​​component 13 and the lock tongue 2 is released. Thus, the lock tongue 2 can be pushed out of the second channel 12 by the elastic energy supply component 14 to realize the unlocking action of the lock tongue 2 and the lock body 1.

[0028] like Figure 3 and Figure 8As shown, the unlock button 3 in this embodiment of the present invention includes a fixed guide 31, a pressing cap 32, and a trigger rod 33 that works in conjunction with the snap-fit ​​component 13. The outer surface of the lower end of the trigger rod 33 is provided with an external thread structure 331, and the inner wall of the pressing cap 32 is provided with an internal thread structure 321 that works in conjunction with the external thread structure 331. A return spring 34 is sleeved on the trigger rod 33. One end of the return spring 34 abuts against the pressing cap 32, and the other end abuts against the fixed guide 31. In use, the fixed guide 31 is installed on the outside of the box, and the trigger rod 33 passes through the fixed guide 31 and is installed in the first channel 11. When the pressing cap 32 is pushed to unlock by applying pressure, since the fixed guide 31 is always in a fixed state, the pressing cap 32 moves and drives the return spring 34 to compress and store energy. When the pressure on the pressing cap 32 is released, the pressing cap 32 automatically springs back to the initial position under the action of the return spring 34, thereby driving the trigger rod 33 to reset for easy use next time.

[0029] like Figure 6 As shown, in this embodiment of the present invention, the upper end of the trigger rod 33 is provided with a second guide slope 332 in cooperation with the first guide slope 1321 of the snap-fit ​​member 13. The second guide slope 332 is set in the opposite direction to the first guide slope 1321. By cooperating with the first guide slope 1321 through the second guide slope 332, the contact surfaces are smoother and less prone to jamming.

[0030] Furthermore, the main cross-sectional shape of the mounting block 151 is an inverted L-shaped block with its opening facing the second channel 12. The snap-fit ​​head 131 of the snap-fit ​​member 13 is attached to the upper end of the mounting block 151, the T-shaped connecting part 133 is attached to the side of the mounting block 151, the free end 132 is attached to the lower end of the mounting block 151, and the unlocking button 3 is movably mounted on the lower end of the mounting block 151 and abuts against the free end 132. Figure 4 As shown in the mid-section view, when the trigger rod 33 is pushed, the cross-sectional area of ​​the part of the trigger rod 33 that contacts the locking member 13 gradually increases. The trigger rod 33 is located at the lower end of the mounting block 151. As the cross-sectional area gradually increases, the entire part remains within the inverted L-shaped opening of the mounting block 151. Thus, the mounting block 151 can avoid the movement of the trigger rod 33 without affecting the fixed installation of the locking member 13. This makes the internal structure of the lock body 1 reasonable and compact, which is conducive to product miniaturization, reduces the occupation of installation space, and avoids the increase in production costs.

[0031] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
