[0003] It can collect various performance test data of power supply through a power equipment test data acquisition device. It is easy to operate and the test data can be traced.

[0004] However, during the data verification and acquisition of power equipment, it is necessary to connect the wires to the equipment being tested to achieve interconnection between the acquisition equipment and the power equipment. When the acquisition equipment is moved, the end of its wires is excessively bent, which leads to damage over time and affects data transmission. This solution does not provide high security protection for equipment data verification and acquisition. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a power supply equipment data acquisition device. It solves the problem that during the data verification and acquisition of power supply equipment, it is necessary to connect the wires to the equipment under test to achieve interconnection between the acquisition device and the power supply equipment. When the acquisition device is moved, the terminal of its wires is excessively bent, which leads to damage over time and affects data transmission.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power equipment data acquisition device, comprising a power equipment data acquisition body and a display module disposed on its top surface and a connecting line connected to its side, wherein the ends of the connecting line are sleeved with an upper fixing clip and a lower fixing clip, and rubber tubes are fixedly connected to both sides of the upper fixing clip, wherein the other end of one of the rubber tubes is fixed to the surface of the power equipment data acquisition body;

[0007] Threaded bolts are inserted into the fixing holes at both ends of the upper and lower fixing clamps. A fixing plate A and a spring A located at the bottom of the fixing plate A are sleeved on the surface of the threaded bolts, and a locking nut is threaded to the bottom end of the threaded bolts to form an elastic fastening mechanism.

[0008] In a specific embodiment, each of the rubber tubes has a cavity inside, and a spring wire is embedded in the cavity; the spring wire extends continuously spirally along the axial direction of the rubber tube to limit the bending curvature of the tube body.

[0009] In a specific embodiment, the spring A is sleeved outside the threaded bolt and its upper and lower end faces respectively abut against the fixing plate A and the lower fixing clamp. When the locking nut is tightened, it compresses the spring A to generate an axial preload.

[0010] In one specific embodiment, the upper fixing clamp and the lower fixing clamp are symmetrically assembled by a pair of threaded bolts; each threaded bolt assembly includes a coaxially penetrating A fixing piece, A spring, and locking nut.

[0011] In one specific embodiment, the rubber tube is a segmented anti-bending protection structure, with the fixing clamp sidewall and the power equipment data acquisition main body shell respectively vulcanized and bonded to its two ends.

[0012] In a specific embodiment, the A fixing piece is a metal stamped ring piece, the inner diameter of which is clearance-fitted with the threaded bolt; the A spring is a stainless steel compression spring, the natural height of which is greater than the depth of the fixing hole.

[0013] Compared with the prior art, the present invention provides a power supply equipment data acquisition device, which has the following beneficial effects:

[0014] The technical solution disclosed in this utility model achieves the function of vibration resistance and anti-loosening of the power connection terminal through the design of an elastic fastening mechanism composed of an upper fixing clamp, a lower fixing clamp, a threaded bolt, a spring A, and a locking nut. When the locking nut is tightened and the spring A is compressed, a continuous axial preload is generated to push the fixing plate A to press the clamp body, which solves the problem of poor contact caused by the loosening of the threaded bolt due to equipment displacement during data acquisition and improves the stability of data transmission. Through the anti-bending structure design of the spring wire inside the rubber tube, the physical protection function of the connection line is achieved. The spring wire extends axially in a spiral in the cavity to form a rigid skeleton, which limits the bending curvature of the rubber tube to not exceed the material critical value, effectively solving the problem of skin damage caused by excessive bending of the wire terminal.

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Figures 1-4 As an embodiment of the present invention, a power equipment data acquisition device includes a power equipment data acquisition body 1 and a display module 2 disposed on its top surface and a connecting line 3 connected to the side. The ends of the connecting line 3 are sleeved with an upper fixing clip 4 and a lower fixing clip 5. Rubber tubes 10 are fixedly connected to both sides of the upper fixing clip 4, and the other end of one of the rubber tubes 10 is fixed to the surface of the power equipment data acquisition body 1.

[0023] The specific problem addressed in this embodiment is: during data verification and acquisition of power supply equipment, it is necessary to connect the conductor to the device under test to achieve interconnection between the acquisition device and the power supply equipment. When the acquisition device is moved, the end of its conductor is excessively bent, leading to damage over time and affecting data transmission. This utility model achieves the function of vibration resistance and anti-loosening of the power connection terminal through the design of an elastic fastening mechanism composed of an upper fixing clamp 4, a lower fixing clamp 5, a threaded bolt 6, an A spring 8, and a locking nut 9. When the locking nut 9 is tightened and compresses the A spring 8, a continuous axial preload is generated to push the A fixing piece 7 to press the clamp body, solving the problem of poor contact caused by the loosening of the threaded bolt 6 due to equipment displacement during data acquisition, and improving the stability of data transmission. Through the anti-bending structure design of the rubber tube 10 with the built-in spring wire 12, the physical protection function of the connecting wire 3 is achieved. The spring wire 12 extends axially in a spiral within the cavity 11 to form a rigid skeleton, limiting the bending curvature of the rubber tube 10 to not exceed the material's critical value, effectively solving the problem of surface damage to the conductor terminal caused by excessive bending.

[0024] Threaded bolts 6 are inserted into the fixing holes at both ends of the upper fixing clamp 4 and the lower fixing clamp 5. A fixing plate 7 and a spring 8 located at the bottom of the fixing plate 7 are fitted onto the surface of the threaded bolt 6. A locking nut 9 is threaded to the bottom of the threaded bolt 6, forming an elastic fastening mechanism. In this specific embodiment, the power supply interface is clamped by the upper and lower fixing clamps at the end of the connecting line 3. Rubber tubes 10 are vulcanized and connected to both sides of the upper fixing clamp 4, with the right rubber tube fixed to the side of the acquisition body 1 to transmit stress. The threaded bolts 6 are inserted through the fixing holes at both ends of the upper and lower fixing clamps. The threaded bolts 6 are sequentially fitted onto the fixing plate 7, compressed by the spring 8, and then threaded to the locking nut 9. When the locking nut 9 is tightened, the compressed spring 8 pushes the fixing plate 7 to press against the fixing clamp, forming an elastic engagement. The linkage design between the elastic fastening mechanism and the rubber tube 10 provides dual protection against vibration, loosening, and bending.

[0025] In this specific embodiment, a cavity 11 is opened inside the rubber tube 10, and a spring wire 12 is embedded in the cavity 11; the spring wire 12 extends continuously spirally along the axial direction of the rubber tube 10 to limit the bending curvature of the tube body.

[0026] The inner cavity 11 of the rubber tube 10 is nested with a spring wire 12. The spring wire 12 is spirally wound along the central axis of the tube to form a rigid support skeleton. When the rubber tube is bent by external force, the elastic limit of the spring wire 12 automatically constrains the deformation curvature of the tube. The axial extension structure 10 of the spring wire 12 in the cavity 11 effectively blocks the transmission of excessive bending stress.

[0027] In this specific embodiment, spring A 8 is sleeved outside the threaded bolt 6 and its upper and lower end faces respectively abut against the fixing plate A 7 and the lower fixing clamp 5. When the locking nut 9 is tightened, it compresses spring A 8 to generate axial preload.

[0028] Spring A 8 is sleeved outside the threaded bolt 6, with its upper and lower ends abutting against the surfaces of fixing plate A 7 and lower fixing clamp 5, respectively. When the locking nut 9 is screwed in, it continuously compresses spring A 8 to generate axial preload.

[0029] In this specific embodiment, the upper fixing clip 4 and the lower fixing clip 5 are symmetrically assembled by a pair of threaded bolts 6; each threaded bolt 6 assembly includes a coaxially penetrating A fixing piece 7, A spring 8 and locking nut 9;

[0030] The upper fixing clamp 4 and the lower fixing clamp 5 are assembled by two pairs of symmetrically distributed threaded bolts 6. Each set of components coaxially passes through the A fixing plate 7 and the A spring 8 and is screwed on to the locking nut 9 to form a uniform force structure.

[0031] In this specific embodiment, the rubber tube 10 is a segmented anti-bending protection structure, with the sidewall of the fixing clip 4 and the housing of the power equipment data acquisition body 1 respectively vulcanized and bonded to both ends.

[0032] The rubber tube 10 adopts a segmented nylon reinforced rubber tube body, and its two ends are respectively bonded to the metal sidewall of the fixing clip 4 and the engineering plastic shell of the collection body 1 through a high-temperature vulcanization process.

[0033] In this specific embodiment, the A fixing piece 7 is a metal stamped circular ring piece, the inner diameter of which is clearance-fitted with the threaded bolt 6; the A spring 8 is a stainless steel compression spring, the natural height of which is greater than the depth of the fixing hole.

[0034] A fixing plate 7 is made of cold-rolled steel plate stamped into a ring-shaped gasket. Its inner hole and the threaded bolt 6 maintain a clearance fit to allow slight deflection. A spring 8 is a stainless steel spring with a free height greater than the depth of the fixing hole to ensure the pre-compression stroke.

[0035] Working principle: The connecting cable 3 is clamped to the power equipment interface by the upper fixing clip 4 and the lower fixing clip 5 connected to the terminal. The threaded bolt 6 passes through the fixing hole and is connected to the A fixing plate 7 and A spring 8 in sequence, and is threaded to the locking nut 9. Tightening the locking nut 9 compresses the A spring 8 and pushes the A fixing plate 7 to press the fixing clip to form an anti-loosening elastic pre-tightening force. At the same time, the spring wires 12 embedded in the rubber tubes 10 on both sides of the upper fixing clip 4 constrain the deformation curvature of the cavity 11 through their own elastic limit, limiting the bending range of the terminal of the connecting cable 3. The end of the rubber tube 10 is fixed to the housing of the acquisition body 1 so that the bending stress is dispersed and transmitted. When displaying data, the working status is fed back in real time by the display module 2 on the top surface of the acquisition body 1.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
