DETAILED DESCRIPTION

[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] like Figures 1-8 As shown, a button-type cabinet door lock structure includes a fixed box 4 and a locking mechanism 5, the fixed box 4 has a cavity suitable for accommodating the locking mechanism 5; the locking mechanism 5 includes a button 51, a locking rod 52 and a reset member 53; the button 51 is suitable for driving the locking rod 52 to reciprocate, and the fixed box 4 has a limiting structure; when the locking rod 52 moves toward the outside of the fixed box 4, the door lock structure is in a locked state under the action of the limiting structure; when the locking rod 52 moves toward the inside of the fixed box 4, the door lock structure is in an unlocked state; when the button 51 is pressed, the door lock structure can be converted from an unlocked state to a locked state or from a locked state to an unlocked state under the action of the reset member 53.

[0034] The fixing box 4 serves as the frame of the door lock structure and is used to be fixed to the door body 1. The fixing box 4 is usually a hollow box with one end open. During installation, the open end of the fixing box 4 fits against the door body 1 to enclose the locking mechanism 5 in the fixing box 4. The end of the fixing box 4 opposite to the open end is the operating end. The button 51 serves as the driving component of the door lock structure. The door body 1 is locked and unlocked by pressing the button 51 from the operating end. The locking rod 52 serves as the executive component of the door lock structure. Since two different effects are achieved through the same action, a limiting structure and a reset member 53 are required. If the locking mechanism 5 is in the unlocked state, press the button 51 at this time, and the locking mechanism 5 is locked and limited by the limiting structure. At this time, the reset member 53 accumulates reset energy. If the button 51 is pressed again, the locking mechanism 5 can be released from the locked state under the reset energy of the reset member 53.

[0035] In a specific embodiment of the present invention, the button 51 and the locking rod 52 are both movably connected to the fixed box 4. The button 51 performs reciprocating linear motion along a first direction, and the locking rod 52 performs reciprocating linear motion along a second direction, where the first direction and the second direction intersect. Because the button 51 and the locking rod 52 move in different directions, their displacement lengths are also different. This allows a larger displacement of the locking rod 52 to be achieved with a smaller displacement of the button 51. Furthermore, the different movement directions of the button 51 and the locking rod 52 can reduce the length of the fixed box 4 and also enable the same button 51 to control the movement of the locking rod 52 in multiple directions.

[0036] In the prior art, only button 51 is used in the power control system to control the start and shutdown of electrical equipment. Complex circuits need to be connected in the control system, and it needs to be controlled by a controller. The button 51 control structure in this application is a completely mechanical structure, and the locking and unlocking of the locking mechanism 5 are achieved through the tiny displacement of the button 51. The overall structure is novel, and it is easy to install and operate.

[0037] The reciprocating motion of the button 51 and the locking rod 52 is linearly limited by the fixing box 4, specifically: Figure 2 and Figure 3 As shown, the fixed housing 4 has a first through-hole 41 and a second through-hole 42, respectively adapted for passage of a button 51 and a locking rod 52. The reset member 53 is a telescopic spring sleeved over the locking rod 52. One end of the locking rod 52 extends out of the fixed housing 4, while the other end is in press contact with the button 51. The telescopic spring is compressed between the locking rod 52 and the end surface of the fixed housing 4. The locking rod 52 preferably has a stepped shaft structure, wherein the portion of the locking rod 52 that passes through the second through-hole 42 is the smallest diameter section. The telescopic spring sleeves over this smallest diameter section and is compressed between the stepped end surface of the locking rod 52 and the inner surface of the fixed housing 4. When the locking mechanism 5 is in the unlocked state, the telescopic spring is approximately free. When the locking mechanism 5 is in the locked state, the telescopic spring is compressed, accumulating reset energy.

[0038] The button 51 includes a fixing portion 511 and a driving portion 512 connected to one end of the fixing portion 511. The fixing portion 511 extends out through the first through hole 41 and is fixed thereto, and reciprocates along the axial direction of the first through hole 41. The driving portion 512 is located inside the fixing box 4 and is in press contact with the locking rod 52. Figure 2 、 Figure 3 and Figure 7As shown, the fixing portion 511 is a column with a diameter slightly smaller than the first through hole 41. The first through hole 41 can be a cylindrical hole or a square hole. When the button 51 is an axially symmetrical structure, the first through hole 41 is preferably a cylindrical hole, which can mainly improve the flexibility of the installation of the button 51. When the button 51 is an axially asymmetric structure, the installation of the button 51 is directional. At this time, the first through hole 41 is preferably a square hole, which is convenient for circumferential limitation of the button 51. The diameter of the end face of the driving portion 512 that docks with the fixing portion 511 is slightly larger than the first through hole 41, so that the driving portion 512 can be ensured to be always located in the fixing box 4. On this basis, the motion conversion between the button 51 and the locking rod 52 can be achieved, but is not limited to, through the following structure: Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 As shown, one end of the locking rod 52 close to the button 51 is a slope 7, and the driving portion 512 has an inclined surface 6 that contacts the inclined surface 7. The distance between the inclined surface 6 and the central axis of the button 51 gradually decreases from the end close to the fixing portion 511 to the end away from the fixing portion 511. When the button 51 is recessed into the first through hole 41, it is in a locked state (as shown in FIG. Figure 3 As shown), the button 51 stops moving under the action of the limiting structure; when the button 51 extends out of the first through hole 41, it is in the unlocked state (as shown Figure 2 As shown), at this time, the button 51 can stop moving by the contact between the driving part 512 and the end surface of the fixed box 4.

[0039] In a specific embodiment of the present invention, the driving portion 512 has a conical structure, and two locking rods 52 are provided. The two locking rods 52 are symmetrically arranged on both sides of the driving portion 512, and a reset member 53 is respectively provided on the two locking rods 52. At this time, the first through hole 41 adopts a circular hole, and the two locking rods 52 respectively move relative to each other in two directions, which can realize the simultaneous locking of two opposite sides of the door body 1, thereby improving the locking effect.

[0040] The structure of the limiting structure is as follows: the limiting structure is provided on the fixing box 4, and the limiting structure can lock and limit the locking rod 52. In a specific embodiment of the present invention, as Figure 4-Figure 6As shown, the locking rod 52 is provided with limiting rods 521 on both sides of the circumference. The limiting structure is a limiting groove 43 located on the fixing box 4. The limiting groove 43 includes an elongated groove portion 431 and a bent portion 432. The elongated groove portion 431 extends along the axial direction of the locking rod 52, and the bent portion 432 is perpendicular to the elongated groove portion 431 or inclined in a direction away from the plane of the second through hole 42. When the limiting rod 521 is located in the bent portion 432, the door lock structure is in the locked state. When the limiting rod 521 is located in the elongated groove portion 431, the door lock structure is in the unlocked state. During this process, the limiting rod 521 is always located in the limiting groove 43. The limiting groove 43 also stabilizes the locking rod 52, preventing the locking rod 52 from being too long and shaking, causing it to disengage from the button 51. The elongated groove portion 431 serves as a telescopic track for the locking rod 52, and the bent portion 432 is used to inhibit the locking rod 52 from further displacement along the axis. When the distance between the inclined surface 6 and the central axis of the button 51 gradually decreases from the end close to the fixing portion 511 to the end away from the fixing portion 511, the bent portion 432 is located at the end of the elongated slot close to the plane where the second through hole 42 is located, and the bending direction of the bent portion 432 is the same as the extension direction of the end of the driving portion 512. Figure 6 and Figure 4 As shown, the limit grooves 43 are located on the side surfaces of the fixing box 4 on both sides of the button 51 in the circumferential direction, and the bent portion 432 is bent to the left by the upper end of the elongated groove portion 431, and the driving portion 512 also extends to the left from the first through hole 41. When the locking rod 52 moves toward the outside of the fixing box 4, the limit rod 521 approaches the plane where the second through hole 42 is located, and at the same time, the driving portion 512 gradually moves to the left. While the driving portion 512 pushes the locking rod 52 along the axial direction of the locking rod 52, it also exerts a leftward force on the locking rod 52. Therefore, when the limit rod 521 reaches the end of the elongated groove portion 431, it has a tendency to move to the left, thereby entering the bent portion 432 and reaching the locked state; when the button 51 is pressed again, under the action of the instantaneous elastic force, the limit rod 521 can slide from the bent portion 432 to the elongated groove portion 431 to reach the unlocked state. When the limiter enters the bent portion 432 or the elongated groove portion 431, the operator can feel a slight click or hear a "click" sound, indicating that the locking or unlocking is successful. In addition, it should be noted that due to the slight lateral displacement of the locking rod 52, there is a clearance fit between the locking rod 52 and the second through hole 42. The locking rod 52 mainly moves along the axial direction of the second through hole 42, and the locking rod 52 can also deflect slightly laterally.

[0041] The bent portion 432 can be perpendicular to the elongated slot portion 431, or it can be tilted in a direction away from the plane where the second through hole 42 is located. At this time, under the squeezing action of the telescopic spring, the limit rod 521 can remain stuck in the bent portion 432. Preferably, the bent portion 432 is tilted in a direction away from the plane where the second through hole 42 is located. On the one hand, it can prevent the limit rod 521 from sliding out of the bent portion 432 when the structure shakes. On the other hand, when in the locked state, the telescopic spring has not reached the contraction limit, and the contact surface between the locking rod 52 and the button 51 has not reached the edge of the driving portion 512. When the button 51 is pressed again, the locking rod 52 first moves a small distance to the outside of the fixed box 4. Under the action of the instantaneous impact, the limit rod 521 jumps from the bent portion 432 to the elongated slot portion 431. Preferably, as Figure 6 As shown, the limiting groove 43 is a J-shaped structure.

[0042] In another specific embodiment of the present invention, Figure 1-Figure 3 As shown, a slider 54 is provided on one end of the locking rod 52 close to the button 51. The button 51 and the slider 54 are in contact with each other, which can increase the contact area of ​​the matching surface and improve the structural stability.

[0043] The present invention also provides a cabinet door, such as Figure 9 As shown, the system comprises a door body 1, a door frame 2, and the aforementioned push-button cabinet door lock structure 3. A fixing box 4 is fixed to the door body 1. The door frame 2 has a receptacle 21 adapted to receive a locking rod 52. When the locking rod 52 is inserted into the receptacle 21, the door body 1 is locked; otherwise, the door body 1 is unlocked. The door frame 2 is a fixed structure, and the fixing box 4 is secured to the door body 1 via screws.

[0044] The push-button cabinet door lock structure 3 of the present invention is generally used for observation windows that need to be opened and closed quickly, and can also be used for cabinet doors 1 of other electrical equipment.
