Description

Technical Field

[0001] This invention relates to the field of power engineering technology, and in particular to a remote opening tool for high-level cabinet doors. Background Technology

[0002] In power system operation and maintenance, distribution cabinets, as key equipment for low-voltage power distribution and metering, are typically installed outdoors, with some cabinets positioned high above the normal standing height of workers. For cabinet doors with pull-type handles, conventional opening methods require maintenance personnel to use insulated ladders to climb and manually insert or pry the lock to release it. This type of operation is not only inefficient but also demands high precision in tool handling and force application due to limited working space, poor visibility, and the need for a dedicated opening device that allows for safe and labor-saving operation from the ground.

[0003] However, existing opening tools generally suffer from simple structure and limited functionality: on the one hand, although traditional insulating rods or hook-shaped tools can achieve remote contact, they lack effective fulcrum and force amplification mechanism, making it difficult to apply a continuous and stable opening force to the pull handle, resulting in laborious operation and easy slippage; on the other hand, existing tools have not been structurally optimized for the lever force characteristics of high-level cabinet doors, making it impossible to achieve reliable insertion and effective prying without climbing, which means that operators still need to climb ladders, bringing safety risks such as falls and electric shock.

[0004] Based on the above problems, we propose a remote opening tool for high-level cabinet doors. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is: how to provide an opening tool that can safely and efficiently open the pull-type or twist-type door handle of the high-level integrated cabinet remotely from the ground, so as to avoid the risks of falling, electric shock and misoperation caused by operators climbing to heights.

[0006] The above-mentioned technical problems are solved by the following technical solution: The present invention proposes a remote opening tool for high-level cabinet doors, which includes an operating lever, a gripper, a connector at one end of the gripper, and a lifting member at one end of the connector; the gripper and the lifting member are not collinear; the lifting member includes a support rod, and the end of the support rod away from the connector is provided with a tip for inserting into the gap of the door handle.

[0020] Reference Figures 1-5 This embodiment provides a remote opening tool for high-level cabinet doors, including an operating lever 1 and a gripper 11, which is convenient for the operator to hold and apply force. A connecting member 12 allows the operating lever 1 to be held vertically or slightly tilted, so that a raised part 13 naturally faces the gap in the cabinet door handle, facilitating the insertion of the pointed tip 132. The raised part 13 is fixedly connected to the connecting member 12 and is located on the outer wall of the connecting member 12. A support area 133 is provided on the outer wall of the raised part 13. When the pointed tip 132 is inserted, the support area 133 contacts the cabinet surface and presses down against the gripper 11. Together, they form a force-saving lever system. With the support area 133 as the fulcrum and the gripper 11 as the lever arm, the downward pressure applied by the operator is converted into a horizontal pulling force on the handle by the tip 132, thereby efficiently opening the cabinet door. With the connection of the connector 12, the gripper 11 and the lifting member 13 are not collinear. The connector 12 can be a straight rod perpendicular to the support rod 131 or an "S"-shaped rod. In this embodiment, an "S"-shaped rod is preferred. The clamping member 14 is provided on the outer wall of the lifting member 13. The clamping member 14 is preferably in two sets and is used to adapt to the remote opening of the twisted door handle.

[0021] In one embodiment provided in this application, the lifting member 13 includes a support rod 131 disposed on the outer wall of the connector 12. The support rod 131 is fixedly connected to the end of the connector 12 away from the gripper 11. The outer wall of the support rod 131 is provided with a tip 132 for inserting into the gap of the door handle. The tip 132 is disposed on the outer wall of the support rod 131 away from the connector 12. The tip 132 may be wedge-shaped. The wedge-shaped design can automatically align and slide into the narrow gap between the pull-type door handle and the cabinet body during the process of approaching the cabinet door, effectively avoiding slippage or failure due to misalignment. Regarding the insertion method, the tip 132 is preferably composed of a pair of mirror-symmetrical inclined surfaces; the outer wall of the support rod 131 is provided with a support area 133, which is a flat or slightly arc-shaped contact surface that directly contacts the cabinet surface during operation, forming the fulcrum of the lever system; when the operator holds the gripper 11 on the ground and presses down on the operating rod 1, the contact point between the support area 133 and the cabinet is used as the fulcrum, the section of the support rod 131 between the tip 132 and the fulcrum is used as the resistance arm, and the main body of the operating rod 1 is used as the power arm, thus forming a typical force-saving lever mechanism. Therefore, the small downward pressure applied by the operator can be amplified into a large horizontal pulling force acting on the door handle, continuously and stably pulling the pull handle outward, thereby achieving smooth opening of the cabinet door.

[0022] In one embodiment provided in this application, the gripper 11 includes an outer rod 111, which is a hollow tubular structure; an inner rod 112 is movably provided inside the outer rod 111, one end of the inner rod 112 is fixedly connected to the connector 12, and the other end slides through the inner cavity of the outer rod 111, so that the inner rod 112 can freely extend and retract along the axial direction of the outer rod 111; by adjusting the extension length of the inner rod 112 relative to the outer rod 111, the effective working length of the entire operating rod 1 can be changed, thereby adapting to the integrated cabinets of different installation heights.

[0023] In one embodiment provided in this application, the outer wall of the inner rod 112 is surrounded by a plurality of elastic clips 113. The elastic clips 113 are made of elastic metal or engineering plastic, and their inner surfaces are tightly fitted with the outer wall of the inner rod 112, while their outer surfaces are provided with inclined guide surfaces. The outer wall of the outer rod 111 is movably threaded with a locking sleeve 114. The outer wall of the outer rod 111 is threaded, and the locking sleeve 114 has a hollow cylindrical structure, with an inner conical surface on its inner wall that matches the inclined surface of the outer surface of the elastic clips 113. The locking sleeve 114, when tightened, secures the plurality of elastic clips. The inner rod 112 is clamped inward by the retracting plate 113. After the operator pulls the inner rod 112 out of the outer rod 111 to the required length according to the height of the integrated cabinet, the locking sleeve 114 is rotated to make it screw along the external thread of the outer rod 111 toward the lifting part 13. At this time, the inner conical surface of the locking sleeve 114 gradually squeezes the outer inclined surface of the elastic clamping plate 113, forcing each elastic clamping plate 113 to undergo elastic deformation inward, thereby tightly clamping the outer wall of the inner rod 112 and forming sufficient frictional resistance to prevent the inner rod 112 from sliding or loosening due to force in subsequent operations.

[0024] In one embodiment provided in this application, the connector 12 is preferably an S-shaped rod structure, with one end fixedly connected to the inner rod 112 and the other end fixedly connected to the support rod 131. When the operating rod 1 is kept in an approximately vertical or slightly inclined position, the S-shaped rod structure causes the support rod 131 at the front end to naturally tilt forward and slightly deflect downward, so that the tip 132 can smoothly engage the narrow gap between the cabinet door handle and the cabinet body without the operator having to significantly adjust the arm angle or apply additional torsional force.

[0025] In one embodiment provided in this application, the clamping member 14 includes a fixing plate 141 disposed on the outer wall of the support rod 131. The fixing plate 141 is preferably vertically fixedly connected to the outer surface of the support rod 131 as the stationary side of the clamping member 14. An electric push rod 142 is provided on the outer wall of the support rod 131. The electric push rod 142 is fixedly installed on the outer wall of the support rod 131, and the motor of the electric push rod 142 is integrated inside the electric push rod 142.

[0026] In one embodiment provided in this application, the outer wall of the electric push rod 142 is provided with a movable plate 143, which is fixed to the output end of the electric push rod 142. The movable plate 143 is arranged parallel to the fixed plate 141 to form a clamping surface. When the electric push rod 142 is energized and extends or retracts, it drives the movable plate 143 to move closer to or further away from the fixed plate 141, thereby achieving clamping or releasing of the door handle. The outer wall of the movable plate 143 is provided with a pressure measuring plate 144, which is a rigid flat plate structure. The inner side is fixedly connected to the movable plate 143, and the outer surface is attached with an anti-slip pad 146.

[0027] In one embodiment provided in this application, a pressure sensor 145 is provided inside the movable plate 143. The pressure measuring plate 144 keeps in contact with the pressure sensor 145 embedded inside the movable plate 143. During the process of the electric push rod 142 driving the movable plate 143 to move towards the fixed plate 141 and clamp the door handle, the clamping force is transmitted to the pressure sensor 145 through the pressure measuring plate 144, which then transmits the real-time pressure signal to the controller 32. Anti-slip pads 146 are provided on the clamping surfaces of the movable plate 143 and the fixed plate 141. The anti-slip pads 146 are used to increase the friction coefficient of the contact surface with the door handle and prevent slippage during the clamping process.

[0028] In one embodiment provided in this application, a stabilizing rod 115 is provided on the outer wall of the outer rod 111. The stabilizing rod 115 is vertically fixed to the outer wall of the outer rod 111. An auxiliary rod 116 is provided on the outer wall of the stabilizing rod 115. The auxiliary rod 116 is fixedly connected to the stabilizing rod 115 and preferably has a "T" shaped structure, which makes it easy for the operator to hold and apply downward pressure or swing force, thus solving the technical defects of traditional single-rod tools that are not easy to hold and are inconvenient to apply force.

[0029] In one embodiment provided in this application, a wireless control module 117 is provided on the outer wall of the outer rod 111. The wireless control module 117 includes an operation button, a wireless transmitting unit, and a power supply. It is used to receive control commands issued by the operator on the ground and send the commands to the controller 134 in the form of wireless signals. The controller 134 is provided inside the support rod 131. The controller 134 is electrically connected to the electric push rod 142 and the pressure sensor 46 through wires, and establishes a wireless communication link with the wireless control module 117. When the wireless control module 117 sends an extension or retraction command, the controller 134 receives and parses the command and controls the electric push rod 142 to perform the corresponding action. At the same time, the pressure sensor 46 feeds back the clamping force on the pressure plate 144 to the controller 134 in real time. When the clamping force reaches a preset safety threshold, the controller 134 automatically cuts off the power supply to the electric push rod 142 and stops the retraction action to prevent over-clamping damage to the door handle or clamping failure.

[0030] When in use, for pull-type door handles, the operator stands on the ground, holds the outer rod 111, and brings the lifting part 13 at the front end of the tool close to the door handle of the high-level platform cabinet; aligning the tip 132 with the gap between the door handle and the cabinet body, and using the wedge-shaped guiding effect of the first inclined surface 33 and the second inclined surface 35, smoothly inserting the tip 132 into the gap; then, continue to press down on the handrail area 11, so that the support area 133 contacts the cabinet surface and forms a lever fulcrum. At this time, with the support area 133 as the fulcrum, the support rod 131 between the tip 132 and the fulcrum as the resistance arm, and the main body of the operating rod 1 as the power arm, a force-saving lever structure is formed; under the continuous downward pressure, the tip 132 applies a pulling force away from the cabinet body to the door handle, ultimately realizing the smooth opening of the cabinet door.

[0031] For the twist-type door handle, the operator sends a command to the controller 134 by pressing the button on the wireless control module 117, controlling the two electric push rods 142 to extend synchronously, so that the movable plate 143 moves away from the fixed plate 141, forming a sufficient clamping opening. Then, the operator adjusts the position of the telescopic part 1 by hand, and clamps the twist-type door handle between the two pairs of clamping surfaces. The operator presses the button on the wireless control module 117 again to send a retraction command. The electric push rods 142 drive the movable plate 143 to move towards the fixed plate 141. The pressure plate 144 contacts the door handle surface with the anti-slip pad 146. The pressure sensor 46 monitors the clamping force in real time and feeds the signal back to the controller 134. When the clamping force reaches the preset safety value, the controller 134 automatically stops the electric push rods 142 from retracting, completing reliable clamping. At this time, the operator swings the operating lever 1, which drives the clamped twist-type door handle to rotate synchronously, thereby opening the cabinet door.

[0032] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
