[0002] Due to the special operating environment and working method of some equipment, certain chambers of the equipment need to be isolated from the outside world during the testing process to prevent external environmental interference or safety accidents. This is to ensure the safety of the specific chambers of the equipment or to avoid personal safety accidents to the operators, so as to avoid unnecessary losses and safety accidents.

[0003] In general, under specific practical conditions or during use, equipment needs to frequently open the protective cover or door of a specific chamber. The protective cover or door of the equipment is mostly designed as a flip door, a sliding door, a rotating cover, etc., and is equipped with various door lock structures. However, these door lock structures are not easy to open the protective cover or door of a specific chamber of the equipment quickly, reliably, and smoothly. Summary of the Invention

[0004] The present invention aims to solve the problem that existing door lock structures are not able to quickly, reliably, and smoothly open the protective cover or protective door of a specific chamber of equipment, and provides a manual linkage button door lock device that can quickly, reliably, and smoothly open the protective cover or protective door of a specific chamber of equipment.

[0005] This utility model discloses a manual linkage type button door lock device, which is installed on the base of a protective cover or door panel. The door lock device is characterized by including a button, a return spring, a mounting cover, a transmission linkage, a transmission rocker, a latch, and a limiting block. The button is elongated and installed on the base. The mounting cover is fitted onto the rear end of the button and fixed to the inner wall of the base. The return spring is located inside the mounting cover and fitted onto the button. The rear end of the button, the transmission linkage, the transmission rocker, and the latch are sequentially connected. The limiting block is fixed above the mounting cover, and the latch protrudes from the limiting block.

[0006] The mounting cover has a central opening and is fitted onto the rear end of the button. Screw holes are provided around the opening. The mounting cover is fixed to the inner wall of the base by screws. The reset spring is fitted onto the rear end of the button, and the tail end of the reset spring contacts the inner wall of the mounting cover.

[0007] The front end of the transmission link is bolted to the rear end of the button, the rear end of the transmission link is bolted to the front end of the transmission rocker, and the rear part of the transmission link is bolted to the bottom of the locking tongue.

[0008] The limiting block is positioned above the mounting cover and fixed to the inner wall of the base by bolts. A limiting hole is provided in the middle of the limiting block, and the locking tongue protrudes from the limiting hole.

[0009] The substrate has a through hole through which the button passes, and the outer diameter of the front end of the button is larger than the inner diameter of the through hole.

[0010] The mounting cover has a connection hole at the bottom, which is connected to the front end of the conductive rocker arm.

[0011] This utility model is a manual linkage button door lock device. Its feature is that, under the condition that a specific cavity of the equipment needs to be sealed, the device simplifies the opening and closing method. It only requires machining concave and convex grooves on the corresponding mating surfaces of the opening and closing door and filling the grooves with the corresponding material to achieve waterproofing, dustproofing and electromagnetic compatibility of the specific cavity of the equipment.

[0016] Example 1: A manual linkage type button door lock device is installed on the base of a protective cover or door panel. The door lock device includes a button, a return spring, a mounting cover, a transmission linkage, a transmission rocker, a latch, and a limiting block. The button is elongated and installed on the base. The mounting cover is fitted onto the rear end of the button and fixed to the inner wall of the base. The return spring is located inside the mounting cover and fitted onto the button. The rear end of the button, the transmission linkage, the transmission rocker, and the latch are sequentially connected. The limiting block is fixed above the mounting cover, and the latch protrudes from the limiting block.

[0017] The mounting cover has a central opening and is fitted onto the rear end of the button. Screw holes are provided around the opening, and the mounting cover is fixed to the inner wall of the base with screws. The return spring is fitted onto the rear end of the button, and the tail end of the return spring contacts the inner wall of the mounting cover.

[0018] The front end of the transmission link is bolted to the rear end of the button, the rear end of the transmission link is bolted to the front end of the transmission rocker, and the rear part of the transmission link is bolted to the bottom of the lock tongue.

[0019] The limiting block is installed above the mounting cover and fixed to the inner wall of the base with bolts. The limiting block has a limiting hole in the middle, and the locking tongue passes through the limiting hole.

[0020] The substrate has a through hole through which the button passes, and the outer diameter of the front end of the button is larger than the inner diameter of the through hole.

[0021] The bottom of the mounting cover has a connection hole, which connects to the front end of the transmission rocker.

[0022] The button passes through a through hole in the base, serving as the power input source for the entire mechanism's movement. A return spring is fitted onto the inner end of the button's round rod, used to restore the button's position after it is pressed. A mounting cover is used to press down the button and the return spring, limiting the button's position and preventing the return spring from falling off. One end of the transmission linkage is mounted on the hinge hole inside the button, and the other end is fixed to the hinge hole in the middle of the transmission rocker, used to transmit the power applied to the outer end of the button to the transmission rocker, providing power to the transmission rocker. One end of the transmission rocker is mounted on the connecting hole at the bottom of the mounting cover, with the middle hinge hole connecting to one end of the transmission linkage, and the other end of the transmission rocker sliding hinge hole connecting to the hinge end of the latch, used to transmit the power transmitted by the transmission linkage to the latch. The latch is fixed to the sliding hinge end of the transmission rocker, used to position and lock the cover or door panel after it is closed. A limit block is fitted onto the latch and fixed to the corresponding position on the cover or door panel, used to limit the latch's movement trajectory to achieve locking and unlocking of the base.
