Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing instrument technology, and in particular to a dedicated wire tester. Background Technology
[0002] Underground conductor detection is a technique for detecting and mapping various underground conductors. It is mainly used to determine the location, direction, and depth of underground conductors, providing accurate conductor distribution information for urban road planning and building construction, avoiding damage to underground conductors during construction, and ensuring the normal operation of urban infrastructure.
[0003] The underground pipeline detector consists of a transmitter (used to apply a detection signal to the pipeline) and a receiver (used to detect the electromagnetic field generated by the pipeline). When operating it, the operator first adjusts the transmitter and connects it to the line to be tested via a signal cable. Then, the operator holds the receiver on the ground to test it, thus locating the direction of the conductor and the location of any damage. Because the receiver's size is fixed, the operator needs to keep the detection end of the receiver as vertical as possible when holding it. However, in this handheld position, it is impossible to maintain the same angle and keep it as close to the ground as possible, which introduces measurement errors. Furthermore, the operator needs to bend over for extended periods during testing. During the test, the operator also needs to record data constantly, requiring the receiver to be placed on the ground, and then picked up again to continue testing, resulting in low efficiency.
[0004] Therefore, it is necessary to invent a dedicated wire tester to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a dedicated wire tester to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dedicated wire tester, comprising a receiver body, a connecting block fixedly connected to the top of the receiver body, a limiting plate fixedly connected to the top of the connecting block, an extension plate slidably disposed on the limiting plate, and a positioning component for positioning the detection end angle of the receiver body disposed at the top of the extension plate, the positioning component including a hinge fixedly connected to the top of the extension plate, a horizontal shaft movably passing through the hinge, spherical grooves being equidistantly formed at the end of the horizontal shaft, a hinge member fixedly passing through the horizontal shaft, and one side of the hinge member being fixed... A rectangular frame is connected, and a second slider is slidably connected inside the rectangular frame. A connecting post is fixedly passed through the second slider, and one end of the connecting post is movably connected to the rectangular frame. A positioning plate is fixedly connected to the end of the connecting post, and a spherical protrusion corresponding to a spherical groove is fixedly connected to one end of the positioning plate at equal intervals in a ring. A limit hole is opened on one side of the rectangular frame, and a toggle block that is slidably connected to the limit hole is fixedly connected to one side of the second slider. A compression spring with its two ends abutting against the second slider and the rectangular frame respectively is sleeved on the outer circumferential surface of the connecting post, and a handle is fixedly connected to the middle of one side of the rectangular frame.
[0007] Preferably, the limiting plate has grooves on both sides, and a first slider that is fixedly connected to the extension plate is slidably connected inside the grooves. The extension plate has a rectangular cavity inside.
[0008] Preferably, a bolt is threadedly connected to one side of the first slider, and the bolt movably passes through a positioning block, with one side of the positioning block slidably connected to the side of the limiting plate.
[0009] Preferably, the bottom of the receiver body is a detection end, and fixing blocks are symmetrically fixedly connected to both sides of the bottom of the receiver body at the detection end. A cross hole is opened inside the fixing block, and an insert block is inserted into the top of the fixing block. Limiting blocks for limiting are symmetrically fixedly connected to both sides of the bottom of the receiver body above the insert blocks.
[0010] Preferably, a horizontal plate is movably inserted into the side of the fixing block, a rectangular hole is opened inside one end of the horizontal plate, the rectangular hole is inserted into the insertion block, and a support wheel is fixedly connected to the other end of the horizontal plate.
[0011] Preferably, a vertical plate with an arc-shaped bottom end is fixedly connected to one side of the bottom of the fixing block, and the height of the vertical plate is set with a height difference of two centimeters from the radius of the support wheel.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] 1. With an adjustable extension plate, users can flexibly adjust it according to their own height. The vertical position is precisely locked by the compression of bolts, positioning blocks and limiting plates, avoiding the problem of operators having to bend over for a long time due to the fixed size of the receiver. At the same time, the unique hinge, horizontal axis and spherical groove structure work together to ensure that the detection end of the receiver body can automatically maintain a vertical state and fixed angle under the action of gravity when handheld detection, without the need for deliberate human control. This significantly improves the stability of the detection angle and the comfort of operation, thereby improving the accuracy of detection.
[0014] 2. With the quick-release support wheels, the operator can easily move the receiver horizontally on the ground by holding the lever without pressing other parts. This allows the operator to operate continuously without frequently placing and picking up the equipment during detection and recording, reducing the number of operation steps, greatly improving the efficiency of underground pipeline detection, and saving manpower and time costs.

[0020] 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.
[0021] Example 1
[0022] This utility model provides, for example Figures 1-4 The diagram shows a dedicated wire tester, comprising a receiver body 1. A connecting block 4 is fixedly connected to the top of the receiver body 1. A limiting plate 5 is fixedly connected to the top of the connecting block 4. An extension plate 6 is slidably mounted on the limiting plate 5. A positioning component for positioning the detection end angle of the receiver body 1 is fixedly mounted on the top of the extension plate 6. The positioning component includes a hinge 7 fixedly connected to the top of the extension plate 6. A horizontal shaft 9 is movably passed through the hinge 7. A spherical groove 901 is equidistantly formed at the end of the horizontal shaft 9. A hinge member 8 is fixedly passed through the horizontal shaft 9. A rectangular frame 10 is fixedly connected to one side of the hinge member 8. Both ends of the frame 10 have round holes. A second slider 13 is slidably connected inside the rectangular frame 10. A connecting post 12 is fixedly connected through the second slider 13. The connecting post 12 is movably connected through the round hole at one end of the rectangular frame 10. A positioning plate 11 is fixedly connected to the end of the connecting post 12. A spherical protrusion 1101 corresponding to the spherical groove 901 is fixedly connected to one end of the positioning plate 11 at equal intervals in a ring. In the natural state, one end of the positioning plate 11 is in contact with the horizontal axis 9. Under the interlocking action of the spherical groove 901 and the spherical protrusion 1101, the positioning plate 11 can restrict the rotation of the horizontal axis 9.
[0023] A limiting hole 1001 is provided on one side of the rectangular frame 10. A toggle block 15 that is slidably connected to the limiting hole 1001 is fixedly connected to one side of the second slider 13. A compression spring 14 with its two ends abutting against the second slider 13 and the rectangular frame 10 respectively is sleeved on the outer peripheral surface of the connecting post 12. A grip rod 16 is fixedly connected to the middle of one side of the rectangular frame 10. When it is necessary to adjust the rotation angle of the receiver body 1, by holding the grip rod 16, the index finger presses the toggle block 15 to one side, thereby driving the second slider 13 to move laterally within the rectangular frame 10. This will compress the spring 14, causing the connecting column 12 and the positioning plate 11 to move to one side, thus disengaging the spherical protrusion 1101 from the spherical groove 901. At this time, under the action of the horizontal axis 9 and the hinge 7, the receiver body 1 is in a natural vertical state due to gravity. Then, the index finger is released, the spring 14 returns to its original position, causing the connecting column 12 and the positioning plate 11 to return to their original position, so that the spherical protrusion 1101 engages with the spherical groove 901, thereby locking the measurement angle of the receiver body 1's detection end and improving the measurement accuracy.
[0024] The limiting plate 5 has grooves on both sides, and a first slider 601 fixedly connected to the extension plate 6 is slidably connected inside the grooves. The extension plate 6 has a rectangular cavity inside. A bolt 17 is threadedly connected to one side of the first slider 601. A positioning block 18 is movably passed through the bolt 17. One side of the positioning block 18 is slidably connected to the side of the limiting plate 5. By rotating the bolt 17, the positioning block 18 is disengaged from the side of the limiting plate 5. Then, the user can adjust the unfolding height of the extension plate 6 according to their own height. Then, by rotating the bolt 17 again, the positioning block 18 is moved to one side of the limiting plate 5, thereby squeezing against the limiting plate 5 and fixing the vertical position of the extension plate 6.
[0025] Example 2
[0026] The bottom of the receiver body 1 is the detection end. Fixing blocks 19 are symmetrically fixedly connected to both sides of the detection end at the bottom of the receiver body 1. A cross hole 1901 is opened inside the fixing block 19. An insert block 20 is inserted into the top of the fixing block 19. Limiting blocks 21 for limiting are symmetrically fixedly connected to both sides of the bottom of the receiver body 1 above the insert block 20. A horizontal plate 22 is movably inserted into the side of the fixing block 19. A rectangular hole 2201 is opened inside one end of the horizontal plate 22, which is inserted into the insert block 20. A support wheel 23 is fixedly connected to the other end of the horizontal plate 22. When the road surface to be detected is a relatively flat plane, the insert block 20 can be lifted first, causing its bottom end to disengage from the horizontal groove of the cross hole 1901. Then, the horizontal plate 22 is horizontally inserted into the cross hole 1901 inside the fixing block 19. Then, loosen the insert 20 so that it is inserted into the rectangular hole 2201, thereby completing the assembly and fixation of the horizontal plate 22 and the fixing block 19, and thus completing the assembly of the support wheel 23, thereby improving the efficiency of testing and the convenience of operation. When it is necessary to remove it, lift the insert 20 so that it is disengaged from the rectangular hole 2201, and the support wheel 23 can be removed as a whole. A vertical plate 1902 with an arc-shaped bottom is fixedly connected to one side of the bottom of the fixing block 19. The height of the vertical plate 1902 and the radius of the support wheel 23 are set with a height difference of two centimeters. When the support wheel 23 is installed, the receiver body 1 can be stood on the ground during testing. Under the action of the support wheel 23 and the vertical plate 1902, a stable support can be formed, which facilitates the tester to record the test data and improves the efficiency of testing.
[0027] The working principle of this utility model is as follows: First, the transmitter 2 is debugged and connected to the line to be tested. Then, the receiver body 1 is taken out. The user can then adjust the unfolded height of the extension plate 6 according to their own height. Then, by rotating the bolt 17 again, the positioning block 18 is moved to one side of the limiting plate 5, thereby squeezing against the limiting plate 5 and fixing the vertical position of the extension plate 6. By holding the handle 16 and pressing the actuating block 15 to one side with the index finger, the second slider 13 is moved laterally within the rectangular frame 10, which squeezes the compression spring 14, thereby moving the connecting column 12 and the positioning plate 11 to one side. This causes the spherical protrusion 1101 to disengage from the spherical groove 901. Under the action of the hinge 7 and the horizontal axis 9, the receiver... Under the influence of gravity, the detection end of the receiver body 1 can always remain vertical and fixed at the same angle. When it is necessary to tilt the bottom surface, by releasing the index finger, the compressed spring 14 is reset, thereby driving the connecting column 12 and the positioning plate 11 to reset, so that the spherical protrusion 1101 engages with the spherical groove 901, thereby locking the measurement angle of the receiver body 1, which facilitates manual adjustment. When measuring on a flat and solid bottom surface, the support wheel 23 is installed on the fixing blocks 19 on both sides of the receiver body 1 and fixed by the insert block 20. At this time, by holding the handle 16, without pressing the actuating block 15, the receiver body 1 can be moved horizontally on the ground under the action of the support wheel 23, and the observed values can be viewed on the display 3, thereby improving the efficiency of the test.
[0028] It should be noted that the fixing block 19, the insertion block 20, the limiting block 21, the horizontal plate 22 and the support wheel 23 are all made of high-hardness plastic material, which will not cause metal interference to the detection end of the receiver body 1. Furthermore, the diameter of the support wheel 23 in this embodiment is not limited.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
