Description

Technical Field

[0001] The utility model belongs to the technical field of industrial plugs, in particular to a combined industrial plug. Background Art

[0002] An industrial plug is a power connection device used in industrial environments. It can transmit electrical energy from the power supply to various electrical equipment, providing energy support for the production process. Industrial plugs are generally divided into two protection levels: IP44 and IP67. IP44 can prevent the intrusion of objects larger than 1.0mm, and prevent the intrusion of mosquitoes, flies, insects or objects with a diameter larger than 1.0mm; while IP67 can prevent the intrusion of dust and water, ensuring the normal operation of lamps, and protecting live parts from exposure, providing protection against electric shock.

[0003] Announcement No. "CN218602801U" discloses a new type of combined industrial plug, comprising a cylinder, one end of which is threadedly connected to a front end cover, and the other end of which is threadedly connected to a rear end cover; one side of the cylinder is slidably connected to a limit block, a connecting plate is inserted into the front side of the cylinder, one end of the connecting plate is located inside the cylinder and is connected to a connecting rod between the limit block, the other end of the connecting plate is fixedly connected to a connecting ring on the outside of the cylinder, and a spring is connected between the connecting plate and the inside of the cylinder. The utility model is designed with a connecting ring, so when unplugging the plug, the connecting ring is first pulled out of the cylinder, and the plug can be unplugged by pulling the connecting ring. At the same time, when the connecting ring is pulled out, the limit block is also retracted into the cylinder, eliminating the need for the user to lift the limit cover of the socket, making it more convenient to use. The movable plate and the terminal block are also designed, so when the plug is not inserted into the socket, the conductive column does not contact the battery cell, so that the battery cell will not be energized, thereby improving safety.

[0004] Although the above-mentioned new type is designed with a movable plate and a terminal board, when the plug is not inserted into the socket, the conductive column does not contact the battery cell, so the battery cell will not be energized, thereby improving safety. However, when the battery cell inside the cylinder fails or is damaged, the entire plug cylinder needs to be replaced, which increases production costs. Moreover, after long-term use, dirt and dust will accumulate inside the cylinder, which will affect the heat dissipation and electrical performance of the equipment. If the plug cylinder is used for a long time without being cleaned, if the cylinder cannot be disassembled, the dirt and dust inside cannot be cleaned, resulting in reduced equipment performance, frequent failures, and even shortened equipment life. Utility Model Content

[0005] In response to the problems mentioned in the background technology, the purpose of the present utility model is to provide a combined industrial plug to solve the problem that when the battery core inside the cylinder fails or is damaged, the entire plug cylinder needs to be replaced, which increases production costs, and the cylinder cannot be disassembled, making it impossible to clean the internal dirt, dust, etc., resulting in reduced equipment performance, frequent failures, and even shortening the service life of the equipment.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A combined industrial plug includes a fixed cylinder, an end cap is threadedly connected to the bottom end of the fixed cylinder, a first connecting ring is fixedly connected to the outer wall of the fixed cylinder, a connecting cylinder is movably connected to the upper end of the fixed cylinder, a second connecting ring is fixedly connected to the outer wall of the connecting cylinder, a connecting block is symmetrically fixedly connected to the bottom end of the second connecting ring, a connecting assembly is installed inside the connecting block, a connecting plate is fixedly connected inside the connecting cylinder, a movable plate is installed inside the connecting cylinder, a telescopic assembly is symmetrically provided between the movable plate and the connecting plate, conductive columns are symmetrically installed on the upper end of the connecting plate through a circumferential array, and battery cells are symmetrically installed on the upper end of the movable plate through a circumferential array;

[0008] The connecting assembly includes a cavity, a first return spring, a press plate, a press block and a clamping block. A cavity is opened inside the connecting block, and the first return spring is symmetrically fixedly connected to one end of the cavity, and the other end of the first return spring is fixedly connected to the press plate. The press plate and the cavity are slidingly connected, and the end of the press plate away from the first return spring is fixedly connected to the press block and the clamping block. The end of the clamping block away from the press plate extends out of the side end of the connecting block, and the end of the press block away from the press plate extends out of the outer wall of the second connecting ring. The upper end of the first connecting ring is symmetrically provided with connecting grooves, and the connecting groove and the connecting block are plug-in. A clamping slot is opened at one end inside the connecting groove, and the clamping slot and the clamping block are clamped. Plug barrels of different specifications or types can be replaced according to actual needs to adapt to different working environments and power requirements, so that the plug can be more widely used in various industrial fields. Moreover, when maintaining or repairing the plug, damaged parts can be conveniently removed and replaced, thereby greatly reducing maintenance time and cost.

[0009] As an optimal technical solution, the bottom end of the second connecting ring is symmetrically fixed with a positioning column, and the upper end of the first connecting ring is symmetrically opened with a positioning hole. The positioning hole and the positioning column are plugged into each other, which reduces connection errors caused by inaccurate positioning and improves the accuracy and efficiency of the connection.

[0010] As an optimal technical solution, the telescopic assembly includes a mounting seat, a first limiting column, a built-in hole, a second limiting column and a second return spring, the upper end of the connecting plate and the bottom end of the movable plate are symmetrically fixedly connected to the mounting seat, the upper end of the mounting seat fixedly connected to the upper end of the connecting plate is fixedly connected to the first limiting column, the upper end of the first limiting column is provided with a built-in hole, the bottom end of the built-in hole is fixedly connected to the second return spring, the other end of the second return spring is fixedly connected to the second limiting column, the second limiting column and the built-in hole are slidably connected, the other end of the second limiting column is fixedly connected to the bottom end of the mounting seat fixedly connected to the bottom end of the movable plate, the first limiting column A third reset spring is sleeved on the outer side of the second limit column, and the head and tail ends of the third reset spring are fixedly connected to the opposite ends of the mounting seat respectively. The bottom end of the movable plate is symmetrically provided with through holes through a circumferential array, and the bottom end of the battery cell is fixedly connected with a connecting hole, which is connected to the through hole. The conductive column passes through the through hole and is plugged into the connecting hole, which effectively avoids accidental power-on due to accidental touch or other reasons, thereby reducing the risk of electric shock and greatly improving the safety of use. Moreover, the battery cell remains in a power-off state when not necessary, which can reduce its workload, reduce wear and aging speed, and thus extend the service life of the battery cell.

The sliders and the sliding grooves are slidably connected, and the movable plate and the inside of the connecting cylinder are slidably connected, which can effectively prevent the movable plate from deflecting or shaking during movement, thereby improving the stability and reliability of the plug.

[0012] In summary, the present invention has the following beneficial effects:

[0013] First, in the present invention, the pressing block is pressed to drive the pressing plate to move the card block, and the pressing plate drives the card block to press the first return spring. The first return spring is compressed, and the card block is retracted into the cavity at the same time. Then the fixed cylinder and the connecting cylinder are merged, so that the first connecting ring and the second connecting ring are fitted together, and the connecting block is inserted into the connecting groove. Then the pressing block is released, the first return spring is reset, the pressing plate rebounds and drives the card block to pop out, and the card block is fixed to the card groove to complete the installation of the connecting cylinder. Plug cylinders of different specifications or types can be replaced according to actual needs to adapt to different working environments and power requirements, so that the plug can be more widely used in various industrial fields. Moreover, when maintaining or repairing the plug, damaged parts can be easily removed and replaced, thereby greatly reducing maintenance time and cost. At the same time, the service life of the industrial plug cylinder can be extended by regularly disassembling, inspecting and replacing worn or aged parts.

[0014] Second, in the present invention, when the plug is not inserted into the socket, there is a gap between the connecting plate and the movable plate, the conductive column does not contact the battery cell, and the exposed battery cell is not energized. When the plug is inserted into the socket, the battery cell is restricted by the socket, so that the battery cell drives the movable plate to press against the connecting plate. At the same time, the second limiting column slides inside the built-in hole to press against the second return spring, the second return spring is compressed, and the third return spring is compressed at the same time. The conductive column passes through the through hole and the connecting hole for plugging, and the battery cell is energized, effectively avoiding accidental energization due to accidental touch or other reasons, thereby reducing the risk of electric shock and greatly improving the safety of use. Moreover, the battery cell remains in a power-off state when not necessary, which can reduce its workload, reduce wear and aging speed, and thus extend the service life of the battery cell. At the same time, users do not need to worry about the battery cell being accidentally energized when the plug is not inserted into the socket, making the plugging and unplugging operation simpler and safer, and improving the user experience.
