Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, and in particular to an environmentally friendly SF6 gas comprehensive testing instrument. Background Technology

[0002] In the field of testing instruments today, existing testing instruments typically use fixed configurations for their support components and handles. While this fixed configuration meets certain functional requirements to some extent, it also brings many inconveniences.

[0003] Traditional testing instruments' support components are designed solely to isolate the instrument from the ground, providing support and ensuring stability during placement, preventing potential wear, corrosion, and other damage from direct contact with the ground. Handles are simply for easy lifting and moving of the instrument between different locations. However, this fixed design has significant drawbacks. In real-world applications, support or lifting operations are not always necessary. For example, when the instrument is operating on a stable surface like a lab bench for extended periods, the fixed support components occupy extra space. In confined spaces, the protruding handles are prone to collisions with surrounding objects. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an environmentally friendly SF6 gas comprehensive testing instrument.

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

[0006] An environmentally friendly SF6 gas comprehensive tester includes a tester housing and a test component disposed within the tester housing. The tester housing has two movable slots and two lifting channels. A movable frame is disposed within the lifting channel, and the movable frame has a compression groove. A limiting block is disposed within the compression groove via a compression mechanism. A limiting port communicating with the movable slots and lifting channels is disposed on the outer wall of the tester housing. A hidden slot is disposed on the outer wall of the tester housing, and a positioning frame extending into the lifting channel is slidably disposed within the hidden slot via a dragging mechanism. A positioning groove is disposed on the outer wall of the movable frame.

[0007] Preferably, the extrusion mechanism includes an extrusion spring disposed in the extrusion groove, with both ends of the extrusion spring connected to the outer wall of the limiting block and the inner wall of the extrusion groove, respectively.

[0008] Preferably, the dragging mechanism includes a dragging spring disposed in a hidden groove, the dragging spring being sleeved on the outside of the positioning frame rod, and the two ends of the dragging spring being connected to the inner wall of the hidden groove and the outer wall of the positioning frame head, respectively.

[0009] Preferably, the movable groove is elongated and is located on the long side of the tester housing.

[0010] Preferably, the lifting channel is U-shaped and is located on the short side of the tester housing.

[0011] Preferably, the limiting port is L-shaped and the movable frame is U-shaped.

[0012] The beneficial effects of this utility model are:

[0013] 1. The movable frame serves two purposes: it acts as a support component, preventing the tester housing from contacting the ground and protecting the equipment; it can also be converted into a handle for easy lifting and transport of the entire device. This flexible functional conversion avoids the limitations of traditional testers where the support components and handles are single-function and fixed.

[0014] 2. The movable frame can be easily switched and disassembled by simply dragging the positioning frame, moving the movable frame horizontally, and pressing the positioning block. The operation is simple and quick, improving the efficiency of use.

[0015] 3. The shapes of components such as the movable slot, lifting channel, limit port, and movable frame are designed to be compatible with each other, ensuring that the components can work together and stably achieve functional conversion. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 An environmentally friendly SF6 gas comprehensive tester includes a tester housing 1 and test components disposed within the tester housing 1, as shown in the figure. The tester housing 1 is also provided with an opening and closing door 13, a reversing valve 14, an inlet pipe 15, and an outlet pipe 16. All of the above components are existing mature components, and their specific structures and working principles are not described in detail here. For details, please refer to the existing technology disclosure.

[0024] The tester housing 1 is provided with two movable slots 2 and two lifting channels 3. The lifting channel 3 is provided with a movable frame 5. The movable frame 5 is provided with a compression slot 10. The compression slot 10 is provided with a limiting block 11 through a compression mechanism. The outer wall of the tester housing 1 is provided with a limiting port 4 that communicates with the movable slots 2 and the lifting channels 3. The outer wall of the tester housing 1 is provided with a hidden slot 6. The hidden slot 6 is provided with a positioning frame 7 that extends into the lifting channel 3 through a dragging mechanism. The outer wall of the movable frame 5 is provided with a positioning slot 9.

[0025] The compression mechanism includes a compression spring 12 disposed in the compression groove 10. The two ends of the compression spring 12 are connected to the outer wall of the limiting block 11 and the inner wall of the compression groove 10, respectively. The elastic potential energy provided by the compression spring 12 can realize the compression of the limiting block 11, ensuring that it is always within the limiting opening 4 when no external force is involved, thereby preventing the movable frame 5 from vertically separating from the movable groove 2 and the lifting channel 3.

[0026] The dragging mechanism includes a dragging spring 8 disposed within the hidden groove 6. The dragging spring 8 is sleeved on the outside of the rod of the positioning frame 7, and its two ends are connected to the inner wall of the hidden groove 6 and the outer wall of the head of the positioning frame 7, respectively. When the movable frame 5 is completely within the lifting channel 3 and is used to support the tester housing 1, the elastic potential energy provided by the dragging spring 8 enables the positioning frame 7 to be dragged, ensuring that its rod is within the positioning groove 9 and guaranteeing the fixed position of the movable frame 5.

[0027] The movable slot 2 is elongated and located on the long side of the tester housing 1. The lifting channel 3 is U-shaped and located on the short side of the tester housing 1. The limiting port 4 is L-shaped, and the movable frame 5 is U-shaped. The above shape design ensures that the components are compatible. For specific shapes, please refer to the attached diagram.

[0028] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0029] When using this utility model, such as Figure 1 As shown, the movable frame 5 is located within the lifting channel 3, and its end is in contact with the ground, so that components such as the tester housing 1 are protected from contact with the ground. At this time, the rod of the positioning frame 7 is located in the positioning groove 9 on the outer wall of the movable frame 5.

[0030] If the above state needs to be changed, first drag the positioning frame 7 so that its rod is separated from the positioning groove 9. Then the movable frame 5 rises to the height of the movable groove 2 and then moves horizontally. The limiting block 11 enters the horizontal part from the vertical part of the limiting port 4. Then the two movable frames 5 move closer to each other to form a handle. With the help of the handle formed by the movable frames 5, the whole device can be easily lifted and transported.

[0031] If the movable frame 5 needs to be disassembled, press the limit block 11 to compress the squeeze spring 12 and make it enter the squeeze groove 10. After it is completely separated from the limit port 4, simply lift the movable frame 5 to separate it from the movable groove 2 or the lifting channel 3.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
