Abstract
Description
Technical Field
[0001] This utility model relates to a clamping frame, and more particularly to a clamping frame for a smart terminal protection device. Background Technology
[0002] In the field of power grid monitoring and control, intelligent terminal devices (such as relay protection devices and power quality analyzers) are increasingly becoming key equipment for the intelligent operation of power grids. These terminal devices typically need to be directly connected to the power grid circuits and operate in complex environments such as outdoor substations and distribution rooms for extended periods, facing severe environmental challenges. Especially during the rainy season, rainwater easily accumulates on the surface of the intelligent terminal casing. If this water seeps into the device through interface gaps, it will cause a series of problems such as short circuits, signal acquisition distortion, and data misinterpretation, seriously affecting the reliability and safety of power grid operation.
[0003] To address these issues, a protective cover is typically added to the outside of the smart terminal. However, existing methods of securing these covers have significant shortcomings: traditional bolt-fastening structures, while reliable, are cumbersome to install and remove, requiring specialized tools and hindering rapid equipment maintenance; while simple snap-fit structures, though efficient, suffer from poor stability, leading to gaps between the cover and the terminal device and exacerbating the risk of rainwater leakage.
[0004] This contradiction between protection requirements and mounting methods is particularly prominent in high-voltage power distribution environments. The stable installation of terminal equipment not only affects the accuracy of monitoring data but also directly impacts the safe and stable operation of the power grid system. Therefore, there is an urgent need to develop a protection device that combines convenient quick installation and removal with long-term operational reliability. As the core fixing component of the protection device, the structural performance of the clamping frame directly determines the overall effectiveness of the protection device, making it a pressing technical challenge in the field of smart terminal protection for power grids. Utility Model Content
[0005] The purpose of this utility model is to provide a clamping bracket for a smart terminal protection device, which solves the technical problems of inconvenient operation and unstable clamping in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A clamping frame for a smart terminal protection device includes a frame, clamping components, guide members, and locking components. The clamping components are in at least two sets and are elastically hinged to the frame. The at least two sets of clamping components are arranged circumferentially on the frame to form a clamping space for clamping the smart terminal. The guide members are drivenly connected to the clamping components and drive the clamping components to flip outward when descending. The locking components are disposed on the frame and lock the guide members when they descend to the correct position.
[0008] Preferably, the clamping assembly includes a jaw and a first elastic element, the jaw is hinged to the frame, and the first elastic element is disposed between the jaw and the frame to drive the jaw to flip inward.
[0009] Preferably, the guide includes a body disposed in a frame and having a guide groove thereon. The inner end of the gripper is inserted into the guide groove. It also includes two limiting rollers, which are inserted into the inner end of the gripper to clamp the upper and lower sides of the body.
[0010] Preferably, the locking assembly includes a U-shaped buckle, and a slot is formed on the body, with the guide moving downward to insert the U-shaped buckle into the slot.
[0011] Preferably, the locking assembly further includes a release bracket, which is slidably inserted into the frame, and pressing down the release bracket causes the buckle to disengage from the slot.
[0012] Preferably, the locking assembly further includes a second elastic element, which is supported at the bottom of the unlocking frame.
[0013] Preferably, the bottom of the unfastening frame is provided with a guide post, which is slidably inserted into the frame, and the second elastic element is sleeved on the guide post.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. Stable and reliable clamping: At least two sets of clamping components are arranged in a ring and continuously contract inward under the drive of the first elastic element (such as a torsion spring) to form a uniform clamping force, ensuring that the smart terminal is firmly clamped and preventing it from loosening or falling off.
[0016] 2. Simple and quick operation: The guide and clamping components are connected by a drive mechanism. Users only need to press down on the guide to make the gripper flip outward, achieving one-click release; the locking component automatically locks the guide to keep the gripper open, making it easy for smart terminals to pick up and put down.
[0017] 3. Smooth and efficient release: The release frame works in conjunction with the second elastic element. Pressing down the release frame will cause the U-shaped buckle to exit the slot. The guide element will automatically rise under the elastic reset action of the clamping component, and the gripper will return to the clamping state. The whole process is smooth and natural.
[0018] 4. Compact and durable structure: The frame adopts a ring design and is made of stainless steel or aluminum alloy, which is lightweight and high-strength; the components are rationally arranged, reducing unnecessary parts, lowering manufacturing costs, and improving service life.
[0019] 5. High versatility: The circumferential arrangement and flexible design of the clamping components can adapt to smart terminals of different sizes and shapes, enhancing the applicability of the device.
[0020] 6. Safety protection: The clamping force is controlled by the elastic element to avoid damage to the smart terminal due to excessive clamping; the locking assembly reliably locks to prevent accidental closure. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] like Figures 1 to 3 As shown, this utility model provides a clamping frame for a smart terminal protection device, which mainly consists of four parts: a frame 1, a clamping component 2, a guide component 3, and a locking component 4.
[0029] The frame 1, serving as the basic support structure for the entire clamping frame, adopts a ring design and is preferably made of corrosion-resistant materials such as stainless steel and aluminum alloy, ensuring both structural strength and controlling overall weight. The frame 1 has multiple mounting positions inside for securing various components.
[0030] The clamping assembly 2 has at least two sets, and in this embodiment, four sets of clamping assemblies 2 are preferably used. They are evenly distributed circumferentially on the frame 1, forming a stable clamping space. Each set of clamping assemblies 2 includes a gripper 21 and a first elastic element 22. The gripper 21 is hinged to the frame 1 via a hinge shaft 23, allowing the gripper 21 to rotate around the hinge shaft 23. The first elastic element 22 is preferably a torsion spring, which is sleeved on the hinge shaft 23, with one end connected to the gripper 21 and the other end connected to the frame 1. In its natural state, the first elastic element 22 continuously applies an inward torque to the gripper 21, causing the gripper 21 to maintain an inward flipping tendency, thereby achieving stable clamping of the smart terminal.
[0031] The guide member 3 includes a body 31, which is disposed within the internal space of the frame 1 and can move vertically. Guide grooves 32 are provided at positions corresponding to the grippers 21 on the body 31. The inner ends of the grippers 21 extend into the guide grooves 32, and two limiting rollers 32 are mounted on the inner ends of the grippers 21. These two limiting rollers 32 are located on the upper and lower sides of the body 31, respectively, maintaining a proper clamping gap with the body 31. When the guide member 3 moves downward, the interaction between the limiting rollers 32 and the body 31 forces the grippers 21 to rotate outward, thereby expanding the clamping space and facilitating the loading and unloading of the smart terminal.
[0032] The locking assembly 4 includes a U-shaped buckle 41, a release bracket 42, and a second elastic member 43. Additionally, a slot 312 is provided on the main body 31. The U-shaped buckle 41 is fixedly installed on the frame 1. When the guide member 3 moves down to a specific position, the U-shaped buckle 41 automatically engages with the slot 312, thus locking and fixing the guide member 3.
[0033] Preferably, the locking assembly also includes a release bracket 42, which is slidably inserted into the frame 1 to enable vertical lifting. When the release bracket 42 is pressed down, its lower end clamps the locking end of the U-shaped buckle 41, causing the locking end to retract under pressure and exit the slot 312.
[0034] In some embodiments, to increase convenience, a second elastic element 43 is provided at the bottom of the release frame 42. This second elastic element 43 supports the bottom of the release frame 42, allowing it to return to its original position and rise after the release frame 42 loses external pressure. To enhance the stability of the second elastic element 43, a guide post 44 is also provided at the bottom of the release frame 42. This guide post 44 has a sliding fit with the frame 1 and can move vertically. The second elastic element 43 is fitted onto the guide post 44.
[0035] Working principle: In its natural state, the clamping assembly 2 flips inward under the elastic action of the first elastic element 22, achieving stable clamping of the smart terminal. When it is necessary to remove the smart terminal, the user presses down on the guide 3. The guide 3, through its cooperation with the limiting roller 32, forces the gripper 21 to flip outward, expanding the clamping space. When the guide 3 moves down to the predetermined position, the U-shaped buckle 41 automatically engages in the slot 312, locking the guide 3 in the lower position. At this time, the gripper 21 remains in the open state.
[0036] When the smart terminal needs to be re-clamped, the user presses down on the release bracket 42. The release bracket 42 pushes the U-shaped buckle 41 to elastically deform, causing it to disengage from the slot 312. At this time, the guide member 3 automatically rises under the restoring force transmitted by the first elastic member 22 through the gripper 21, and the gripper 21 flips inward to restore the clamping state. The release bracket 42 automatically resets under the elastic force of the second elastic member 43.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
