Description

Technical Field

[0001] This utility model relates to the field of ultrasonic flaw detector technology, specifically to a drop-proof structure for an ultrasonic flaw detector. Background Technology

[0002] An ultrasonic flaw detector is a portable industrial non-destructive testing instrument that can quickly, conveniently, non-destructively, and accurately detect, locate, evaluate, and diagnose various internal defects (cracks, porosity, air holes, inclusions, etc.) in workpieces.

[0003] Currently, ultrasonic flaw detectors are often moved or operated in complex working environments, such as factory assembly lines and outdoor construction sites, inevitably facing accidental collisions and drops. Because the flaw detector contains components such as signal processing modules and displays, these components are extremely sensitive to impact and vibration. Once subjected to severe external forces, they are prone to malfunctions such as loose components, broken circuits, or shattered displays. This not only affects the normal operation of the inspection work but may also lead to inaccurate test data due to equipment damage. Therefore, we need to propose a drop-proof structure for ultrasonic flaw detectors. Utility Model Content

[0004] The purpose of this utility model is to provide a drop-proof structure for an ultrasonic flaw detector. The flaw detector body is encased in a drop-proof shell to prevent direct contact with the ground upon drop, thus protecting the flaw detector body. Through the cooperation of a slider and a sliding groove, when the lower frame contacts the ground, the support plate can move a short distance within the lower frame via the slider and sliding groove, buffering the external force. With the addition of a cushioning sponge pad, when the upper frame contacts the ground, the flaw detector body compresses the cushioning sponge pad, using the elasticity of the cushioning sponge pad to further buffer the external force. These solutions reduce the impact of external forces on the flaw detector upon drop, protecting it from malfunctions such as loose components, broken circuits, or shattered displays caused by drops, minimizing the impact on testing operations, and preventing damage that could lead to inaccurate test data, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drop-proof structure for an ultrasonic flaw detector, comprising a drop-proof shell for protecting the ultrasonic flaw detector and a flaw detector body.

A sliding groove adapted to the slider is opened on the inner side wall of the lower frame. An elastic mechanism for assisting the support plate to reset is provided at the bottom end of the support plate. The structure also includes a connecting mechanism for combining and connecting the upper frame and the lower frame.

[0006] Preferably, the elastic mechanism includes a limiting plate bolted to the inner cavity of the lower frame, the limiting plate being located directly below the support plate, and elastic structures being provided around the limiting plate, the top end of the elastic structures being connected to the bottom end of the support plate.

[0007] Preferably, the elastic structure includes a movable hole formed on the surface of the limiting plate, a movable rod slidably inserted into the inner cavity of the movable hole, the top end of the movable rod being bolted to the bottom end of the support plate, a limiting block for limiting the movement range of the movable rod being bolted to the bottom end of the movable rod, and a spring being sleeved on the outer surface of the movable rod, with the spring located between the limiting plate and the support plate.

[0008] Preferably, the surface of the support plate is provided with a fixing groove for fixing the ultrasonic flaw detector, and a shock-absorbing pad is bonded and fixed to the bottom of the inner cavity of the fixing groove.

[0009] Preferably, a buffer silicone pad is bonded and fixed to the upper surface of the upper frame, and the buffer silicone pad is circular.

[0010] Preferably, a cushioning air pad is bonded and fixed to the surface of the lower frame, and four sets of the cushioning air pad are provided, which are distributed at the four corners of the lower frame.

[0011] Preferably, the connecting mechanism includes a connecting groove at the top of the lower frame and a connecting plate adapted to the connecting groove.

[0014] This utility model provides a drop-proof structure for an ultrasonic flaw detector. The flaw detector body is encased in a drop-proof shell, preventing direct contact with the ground upon drop and protecting the device. Through the cooperation of a slider and a sliding groove, when the lower frame contacts the ground, the support plate can move a short distance within the lower frame via the slider and groove, buffering the external force.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an ultrasonic flaw detector anti-drop structure, including an anti-drop shell 1 for protecting the ultrasonic flaw detector and a flaw detector body 2. The anti-drop shell 1 includes an upper frame 11 and a lower frame 12. A buffer sponge pad 3 is glued and fixed to the bottom end of the upper frame 11. A support plate 4 for placing the ultrasonic flaw detector is provided in the inner cavity of the lower frame 12. A slider 5 is integrally formed on all four sides of the support plate 4. A sliding groove adapted to the slider 5 is opened on the inner side wall of the lower frame 12. An elastic mechanism 6 for assisting the support plate 4 to reset is provided at the bottom end. It also includes a connecting mechanism 7 for combining and connecting the upper frame 11 and the lower frame 12.

[0023] In use, the upper frame 11 and lower frame 12 are opened, and the flaw detector body 2 is placed on the support plate 4 inside the lower frame 12. Then, the upper frame 11 and lower frame 12 are combined and fixed by the connecting mechanism 7. After combination, the anti-drop shell 1 protects the flaw detector body 2. When the flaw detector body 2 falls, when the lower frame 12 contacts the ground, the support plate 4 can move a short distance inside the lower frame 12 through the slider 5 and the slide groove to buffer the external force. When the upper frame 11 contacts the ground, the flaw detector body 2 squeezes the buffer sponge pad 3. The buffer sponge pad 3 itself buffers the external force. The above scheme reduces the impact of external force on the flaw detector when falling, protects the flaw detector, and avoids failures such as loose components, broken circuits or broken display screens caused by falling, reduces the impact on the detection work, and avoids damage that leads to inaccurate detection data.

[0024] The elastic mechanism 6 includes a limiting plate 61 bolted to the inner cavity of the lower frame 12. The limiting plate 61 is located directly below the support plate 4. Elastic structures are provided around the limiting plate 61. The top of the elastic structure is connected to the bottom of the support plate 4. When the lower frame 12 is in contact with the ground, it is affected by the weight of the flaw detector body 2, which causes the support plate 4 to move downward. The distance of movement buffers the external force. At the same time, the support plate 4 squeezes the elastic structure when it moves downward. After the squeezing of the elastic structure ends, the elastic structure rebounds and pushes the support plate 4 to reset. Through the setting of the elastic structure, the weight of the flaw detector body 2 on the support plate 4 can be supported.

[0025] The elastic structure includes a movable hole 62 formed on the surface of the limiting plate 61. A movable rod 63 is slidably inserted into the inner cavity of the movable hole 62. The top end of the movable rod 63 is bolted to the bottom end of the support plate 4. A limiting block 64 for limiting the movement range of the movable rod 63 is bolted to the bottom end of the movable rod 63. A spring 65 is sleeved on the outer surface of the movable rod 63, and the spring 65 is located between the limiting plate 61 and the support plate 4. When the support plate 4 moves downward, it compresses the spring 65. After the compression ends, the spring 65 rebounds to provide support force, pushing the support plate 4 to move upward and reset the support plate 4. Through the cooperation of the movable rod 63 and the movable hole 62, the support plate 4 is supported on all sides, improving the stability of the support plate 4 when moving up and down. At the same time, the movable rod 63 can support the inside of the spring 65 to prevent the spring 65 from tilting after being compressed. The spring 65 can support the weight of the flaw detector body 2 on the support plate 4.

[0026] This embodiment also includes buffer pads bonded to both sides of the limiting plate 61. The surface of the buffer pad has a circular hole with a diameter larger than that of the spring 65 and smaller than that of the limiting block 64. With the buffer pad, when the support plate 4 moves downward and squeezes the spring 65 to the bottom, it will first contact the buffer pad. The buffer pad will buffer the external force. When the external force ends, the spring 65 will reset and push the movable rod 63 to move upward. The limiting block 64 at the bottom of the movable rod 63 will first contact the buffer pad. The buffer pad will reduce the kinetic energy of the support plate 4 moving upward and prevent vibration after reset from affecting the flaw detector body 2.

[0027] The surface of the support plate 4 is provided with a fixing groove 8 for fixing the ultrasonic flaw detector. A shock-absorbing pad 9 is glued and fixed to the bottom of the inner cavity of the fixing groove 8. The fixing groove 8 is used to fix the flaw detector body 2, so as to prevent the flaw detector body 2 from moving and colliding inside the anti-drop shell 1 after installation. The shock-absorbing pad 9 is used to buffer the vibration generated when the support plate 4 moves downward, reduce the impact of vibration on the flaw detector body 2, and improve the buffering effect.

[0028] A buffer silicone pad 10 is bonded and fixed to the upper surface of the upper frame 11. The buffer silicone pad 10 is circular. When the upper frame 11 comes into contact with the ground, the buffer silicone pad 10 comes into contact with the ground first. The buffer silicone pad 10 provides initial buffering of external forces, reducing the force transmitted to the anti-drop shell 1.

[0029] A cushioning air pad 21 is bonded and fixed to the surface of the lower frame 12. There are four sets of cushioning air pads 21, which are distributed at the four corners of the lower frame 12. By setting the cushioning air pads 21, the four corners of the lower frame 12 are wrapped. When it falls, the four corners of the anti-fall shell 1 come into contact with the ground. The cushioning air pads 21 can buffer the contact force and reduce the impact of external force on the flaw detector body 2.

[0030] The connecting mechanism 7 includes a connecting groove 72 at the top of the lower frame 12 and a connecting plate 71 adapted to the connecting groove 72. The connecting plate 71 is fixedly connected to the bottom of the upper frame 11, and a connecting hole 73 is formed on the surface of the connecting plate 71. A threaded hole 74 is formed on the outer wall of the lower frame 12, and the inner cavity of the threaded hole 74 communicates with the inner cavity of the connecting groove 72. A self-locking bolt is threaded into the inner cavity of the threaded hole 74, and one end of the self-locking bolt passes through the threaded hole 74 and engages with the inner cavity of the connecting hole 73. The connection between the connecting plate 71 and the connecting groove 72 is described. When the upper frame 11 and the lower frame 12 are combined, the connecting plate 71 is inserted into the inner cavity of the connecting groove 72, and then the self-locking bolt is inserted into the threaded hole 74. The self-locking bolt is rotated clockwise so that it passes through the threaded hole 74 and extends into the inner cavity of the connecting hole 73, where it engages with the connecting hole 73. This achieves the combination of the upper frame 11 and the lower frame 12, avoiding the integrated design of the shockproof shell 1 and facilitating the maintenance and replacement of the internal parts of the shockproof shell 1.

[0031] The upper frame 11 has an integrally formed support block 22 on its surface, and the lower frame 12 has a support groove 23 that matches the support block 22 on its surface. Through the cooperation of the support block 22 and the support groove 23, the connection between the upper frame 11 and the lower frame 12 can be supported around the perimeter, thereby improving the stability of the connection between the upper frame 11 and the lower frame 12.

[0032] In this embodiment, the flaw detector body 2 is set to the IME1150 ultrasonic flaw detector. The surface of the shockproof shell 1 has a connection port. The connection cable of the external device can be connected to the connector of the ultrasonic flaw detector through the connection port. When the support plate 4 moves inside the shockproof shell 1, the connector of the ultrasonic flaw detector is always in the inner cavity of the connection port and will not collide with the connection port. There is no interference between the connection port and the connector.

[0033] In practical use: First, place the flaw detector body 2 on the support plate 4 inside the lower frame 12, move it to the inner cavity of the fixing groove 8 to fix the position of the flaw detector body 2, then cover it with the upper frame 11, the buffer sponge pad 3 at the bottom of the upper frame 11 presses against the upper surface of the flaw detector body 2, insert the connecting plate 71 into the inner cavity of the connecting groove 72, insert the self-locking bolt into the threaded hole 74, rotate the self-locking bolt clockwise so that the self-locking bolt passes through the threaded hole 74 and extends into the inner cavity of the connecting hole 73, and engages with the connecting hole 73 to form a shockproof shell 1 to protect the flaw detector body 2;

[0034] Upon impact, when the upper frame 11 contacts the ground, the flaw detector body 2, through its own weight and external force, applies force to the support plate 4. The support plate 4 moves downward through the cooperation of the slider 5 and the slide groove, buffering the external force by moving downward. The support plate 4 then contacts the surface of the buffer pad, further buffering the external force through the buffer pad, reducing the impact of the falling force on the flaw detector body 2. Simultaneously, the downward movement compresses the spring 65. After buffering, the spring 65 rebounds, pushing the support plate 4 to reset. During reset, the limiting block 64 at the bottom of the moving rod 63 first contacts the buffer pad, mitigating the impact of the reset force. The system can buffer the impact of vibrations during reset on the flaw detector body 2. When the upper frame 11 contacts the ground, the initial contact force is buffered by the buffer silicone pad 10. The flaw detector body 2 is compressed by its own weight, and the elasticity of the buffer foam pad 3 is used to buffer the compression force, thus protecting the flaw detector body 2. The above scheme reduces the impact of external forces on the flaw detector when it falls, protects the flaw detector, and prevents malfunctions such as loose components, broken circuits, or broken displays caused by falling, thereby reducing the impact on the detection work and preventing damage that could lead to inaccurate detection data.

[0035] 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.
