An overload protection structure for a reclosing connection plate

Abstract

This utility model discloses an overload protection structure for a reclosing connection plate, including a gate body, a mounting groove, an automatic opening and closing gate, and a recess. The mounting groove has a slot, and the automatic opening and closing gate has a square groove with a block slidably connected thereto. A round rod extending into the slot is fixedly connected to the end of the block. The gate body has a limiting component for limiting the block's movement. In this utility model, when the fixed block moves to the notch, it pushes the connecting block until the round rod disengages from the slot. The operator's fingers hook onto the round rod, allowing force to be applied, thus disengaging the automatic opening and closing gate from the mounting groove. This allows the operator to more effectively apply force to the automatic opening and closing gate, ensuring it disengages from the mounting groove.

Description

Technical Field

[0001] This utility model relates to the field of reclosing technology, and in particular to an overload protection structure for a reclosing connection plate. Background Technology

[0002] Reclosing devices are typically equipped with both manual and automatic tripping switches. When a short circuit or other event causes an overload on the connecting plate, the circuit is automatically disconnected by the tripping switch, protecting the switching equipment. After circuit maintenance, the automatic tripping switch must be reinstalled in its corresponding position on the reclosing device.

[0003] However, because the notch on the automatic recloser is small and workers wear gloves when installing or removing it, the friction is reduced, making it difficult to remove the automatic recloser quickly and easily. Therefore, the traditional recloser needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide an overload protection structure for a reclosing connection plate in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An overload protection structure for a reclosing connection plate includes a gate body, a mounting groove, an automatic opening and closing gate, and a recess. The mounting groove has a slot, the automatic opening and closing gate has a square groove, and a block is slidably connected to the square groove. A round rod extending into the slot is fixedly connected to the end of the block, and the gate body is provided with a limiting component to limit the block.

[0007] Preferably, the limiting member includes a screw hole and a notch opened in the mounting groove, the screw hole is connected to a screw rod by a thread, and a fixing block is fixed to the end of the screw rod, the fixing block abutting against the end of the block.

[0008] Preferably, the outer wall of the fixing block has evenly distributed protrusions to increase friction.

[0009] Preferably, the automatic opening and closing gate is provided with a connecting groove that connects to the square groove, and a connecting block that is slidably connected to the connecting groove is fixed on the square block.

[0010] Preferably, the end of the connecting block protrudes from the front surface of the automatic opening and closing circuit breaker, meaning that the connecting block can be moved laterally by pushing it with a finger.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] 1. This application moves the fixing block to the notch and pushes the connecting block until the round rod is disengaged from the slot. The operator's fingers hook on the round rod and apply force to the round rod, so that the automatic opening and closing circuit breaker is disengaged from the installation slot. The operator can better apply force to the automatic opening and closing circuit breaker so that the automatic opening and closing circuit breaker is disengaged from the installation slot.

[0013] 2. This application features a connecting block whose end protrudes from the front surface of the automatic opening and closing circuit breaker. This allows the connecting block to be pushed laterally by a finger, and the round rod can be disengaged or inserted into the slot during the movement of the connecting block, which is quite convenient.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] This utility model provides a technical solution, please refer to Figure 1-5 :

[0024] An overload protection structure for a reclosing connection plate includes a gate body 1, a mounting groove 2, an automatic opening / closing switch 6, and a recess 7. The operator installs the automatic opening / closing switch 6 into the mounting groove 2 via the recess 7. This is a direct reference to existing technology and will not be elaborated upon here. A locking groove 3 is provided within the mounting groove 2. A square groove 8 is provided on the automatic opening / closing switch 6, and a block 10 is slidably connected to the square groove 8. A round rod 11 extending into the locking groove 3 is fixedly connected to the end of the block 10. A limiting component is provided on the gate body 1 to limit the movement of the block 10. The operator can apply force to the round rod 11 by hooking their finger on it, causing the automatic opening / closing switch 6 to disengage from the mounting groove 2.

[0025] Example 2:

[0026] The technical solution is basically the same as that in Embodiment 1, except that, as Figure 5 As shown, the limiting component includes a screw hole 5 and a notch 4 opened in the mounting groove 2. The screw hole 5 is threadedly connected to a screw rod 13, and a fixing block 14 is fixed to the end of the screw rod 13. The fixing block 14 abuts against the end of the block 10. The outer wall of the fixing block 14 has evenly distributed protrusions 15 to increase friction. The protrusions 15 allow the operator to easily rotate the fixing block 14, thereby changing the position of the fixing block 14 until it moves to the notch 4, making it easy to remove the automatic opening and closing switch 6 from the mounting groove 2.

[0027] Example 3:

[0028] The technical solution is basically the same as that in Embodiment 1, except that, as Figure 5 As shown, the automatic opening and closing gate 6 has a connecting groove 9 that connects to the square groove 8, and a connecting block 12 that is slidably connected to the connecting groove 9 is fixed on the square block 10. The end of the connecting block 12 protrudes from the front surface of the automatic opening and closing gate 6, meaning that the connecting block 12 can be pushed laterally by a finger.

[0029] In summary, when disassembling the automatic installation gate 5 provided in this embodiment, the fixing block 14 is rotated by the finger through the protrusion 15, so that the screw 13 is connected to the screw hole 5 by threads until the fixing block 14 moves to the notch 4. The connecting block 12 is pushed until the round rod 11 is disengaged from the slot 3. The operator's finger hooks on the round rod 11, and force is applied to the round rod 11, so that the automatic opening and closing gate 6 is disengaged from the installation slot 2.

[0030] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
