Description

Technical Field

[0001] This utility model relates to the field of depth sounders, and in particular to a lifting depth sounder. Background Technology

[0002] A depth sounder is an instrument used to measure the depth of water bodies. It is widely used in marine surveys, hydrological measurements of rivers and lakes, waterway maintenance, and underwater engineering. It determines the depth of the seabed using sonar or other technical means.

[0003] Existing technologies, such as the utility model patent with publication number CN210719161U, disclose a depth sounder. This patent employs a sleeve fitted over a vertical rod and two sets of limiting plates. One limiting plate is fixed to the outer wall of the sleeve, while the other limiting plate slides vertically and is connected to the sleeve. Clamping plates are fixed to opposite sides of both sets of limiting plates, and the sleeve is equipped with locking devices. First, the two sets of clamping plates are clamped to their corresponding ship's side rods. Then, the locking devices bring the two sets of limiting plates closer together and lock them in place. At this point, the inner sides of both sets of clamping plates are clamped to their corresponding ship's side rods. This method is more stable than the existing connection method of clamping onto a single set of ship's side rods. Furthermore, even if the two sets of ship's side rods have different thicknesses or spacing, the two sets of clamping plates can still clamp their respective ship's side rods, making it more versatile. This utility model improves the stability of the transducer.

[0004] The inventors discovered in daily use that the inflexible adjustment of the lifting position in existing technologies leads to a decrease in the accuracy of depth measurement, especially in areas with complex terrain or large water depth variations. The inability to adjust the working position of the depth sounder as needed results in inaccurate bottom measurements. Furthermore, the lack of lifting adjustment function forces operators to rely on fixed depth settings, making it inconvenient to use in scenarios with different water depths and reducing the flexibility of measurement.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies.

[0007] To solve the above technical problems, this utility model provides a lifting depth sounder, including: a handle, an adjustment structure, and an auxiliary structure. A connecting rod is provided at one end of the handle, and the connecting rod is connected to the handle via the auxiliary structure. A measuring device is provided at the end of the connecting rod away from the handle, and the measuring device is connected to the connecting rod via the adjustment structure. An adjustment structure is provided at the end of the connecting rod near the measuring device. The adjustment structure includes an extension rod, which is slidably connected to the connecting rod. Slide grooves are provided on both sides of the connecting rod, and a connecting rod is slidably connected to the inner wall of each slide groove. A button is fixedly connected to the end of the rod away from the connecting rod. A slide plate is fixedly connected to the end of the connecting rod away from the button. Connecting grooves are formed on the inner walls of both sides of the extension rod. The connecting grooves are slidably connected to the slide plate. Several springs are provided on the inner wall of the connecting groove. The two ends of the springs are fixedly connected to the slide plate and the connecting groove, respectively. A locking strip is fixedly connected to the side of the slide plate near the connecting plate. Several locking slots are formed on the inner wall of the connecting rod. The locking slots are engaged with the locking strips. A magnetic sheet is fixedly connected to the end of the connecting rod that is close to the measuring device. The extension rod is fixedly connected to the measuring device.

[0008] The effect achieved by the above components is as follows: when the length of the measuring device needs to be adjusted, pressing the button moves the connecting rod, which in turn moves the sliding plate. The sliding plate causes the spring to contract, and the sliding plate slides on the inner wall of the connecting groove. The sliding plate then moves the locking strip, which separates from the slot. The extension rod then extends, causing the connecting rod to slide on the inner wall of the slide groove. After moving to the appropriate position, the button is released, the spring stretches, and the sliding plate returns to its original position. The sliding plate then causes the locking strip to engage with the slot for fixation.

[0009] Preferably, the button has several slots on the side away from the connecting rod, and the slots are evenly distributed on the button.

[0010] The effect achieved by the above components is that the groove can increase the friction between the hand and the button, preventing slippage when the button is pressed.

[0011] Preferably, both ends of the extension rod are fixedly connected to limit rods, and the limit rods are slidably connected to the connecting rod.

[0012] The effect achieved by the above components is that the limiting rod can limit the extension rod, prevent the extension rod from deviating when sliding, and improve the stability of the extension rod sliding.

[0013] Preferably, a telescopic rod is fixedly connected inside the connecting groove, the telescopic rod is fixedly connected to the slide plate, and the spring is sleeved on the arc surface of the telescopic rod.

[0014] The effect achieved by the above components is that the telescopic rod can limit the spring, prevent the spring from deforming during use, and improve the service life of the spring.

[0015] Preferably, the connecting rod has an auxiliary structure at one end near the handle. The auxiliary structure includes a limiting block, which is fixedly connected to the connecting rod. A rotating shaft is rotatably connected to the inner wall of the limiting block. A connecting block is fixedly connected to the arc surface of the rotating shaft. The connecting block is fixedly connected to the handle. A knob is slidably connected to one end of the rotating shaft. Several insert rods are fixedly connected to the side of the knob near the limiting block. Several insertion holes are opened on the side of the limiting block near the insert rods. A tension spring is sleeved on the arc surface of the rotating shaft. The two ends of the spring are fixedly connected to the knob and the limiting block, respectively.

[0016] The effect achieved by the above components is as follows: when it is necessary to adjust the grip of the depth measuring device, pull the knob to move it, the knob drives the tension spring to stretch, the knob drives the insertion rod to separate from the insertion hole, then move the handle to move it, the handle drives the connecting block to move it, the connecting block drives the rotating shaft to move it, the rotating shaft rotates on the inner wall of the limiting block, after moving to the appropriate angle, then align the insertion rod with the insertion hole, then release the knob to retract the tension spring to drive the insertion rod to be inserted into the insertion hole for fixation.

[0017] Preferably, the knob has a plurality of auxiliary grooves on its arc surface, and the plurality of auxiliary grooves are evenly distributed on the knob.

[0018] The effect achieved by the above components is that the auxiliary groove can increase the friction between the knob and the hand, preventing slippage when turning the knob.

[0019] Preferably, the cross-section of the rotating shaft is circular, and the rotating shaft is a stainless steel shaft.

[0020] The effect achieved by the above components is that the stainless steel material can increase the service life of the shaft and prevent the shaft from rusting during use.

[0021] Compared with related technologies, the lifting depth sounder provided by this utility model has the following beneficial effects:

[0022] This invention provides a lifting depth sounder. By incorporating an adjustable structure, it addresses the limitations of existing technologies where the inability to flexibly adjust the lifting position leads to reduced accuracy in depth measurement. This is particularly problematic in areas with complex terrain or significant water depth variations, where the working position of the depth sounder cannot be adjusted as needed, resulting in inaccurate bottom measurements. Furthermore, the lack of lifting adjustment functionality forces operators to rely on fixed depth settings, making it inconvenient to use in various water depths and reducing measurement flexibility. This device allows for convenient adjustment of the depth sounder's length, preventing it from being unusable in certain special environments. The adjustable depth sounder can meet the needs of most usage scenarios.

[0023] By setting up an auxiliary structure, the grip angle of the depth sounder can be easily adjusted, preventing it from slipping out of your hand in some special environments. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 5 The present invention provides a lifting depth sounder, comprising: a handle 1, an adjustment structure 4, and an auxiliary structure 5. A connecting rod 2 is provided at one end of the handle 1, and the connecting rod 2 is connected to the handle 1 via the auxiliary structure 5. A measuring device 3 is provided at the end of the connecting rod 2 away from the handle 1, and the measuring device 3 is connected to the connecting rod 2 via the adjustment structure 4. The adjustment structure 4 is provided at the end of the connecting rod 2 near the measuring device 3, and the auxiliary structure 5 is provided at the end of the connecting rod 2 near the handle 1.

[0033] In the embodiments of this utility model, please refer to Figures 2 to 4The adjusting structure 4 includes an extension rod 402, which is slidably connected to a connecting rod 2. Both sides of the connecting rod 2 have sliding grooves 401, and a connecting rod 406 is slidably connected to the inner wall of each groove 401. A button 403 is fixedly connected to the end of the connecting rod 406 away from the connecting rod 2, and a sliding plate 411 is fixedly connected to the end of the connecting rod 406 away from the button 403. Both sides of the extension rod 402 have connecting grooves 408 on their inner walls, and the connecting grooves 408 are slidably connected to the sliding plate 411. The inner wall of the connecting groove 408 is provided with several springs 410. The two ends of the springs 410 are fixedly connected to the slide plate 411 and the connecting groove 408 respectively. The two ends of the slide plate 411 are fixedly connected to the side of the connecting plate. The inner wall of the connecting rod 2 is provided with several slots 413. The slots 413 are engaged with the slots 412. The ends of the connecting rod 2 and the measuring device 3 that are close to each other are fixedly connected to magnetic sheets 404. The extension rod 402 is fixedly connected to the measuring device 3. When the length of the measuring device 3 needs to be adjusted, the button 403 is pressed to move it. The button 403 moves the connecting rod 406, which in turn moves the slide plate 411. The slide plate 411 causes the spring 410 to retract, and the slide plate 411 slides on the inner wall of the connecting groove 408. The slide plate 411 moves the locking strip 412, which then separates from the slot 413. The extension rod 402 is then extended, and the extension rod 402 moves the connecting rod 406 on the inner wall of the slide groove 401. After moving to the appropriate position, the button 403 is released, and the spring 410 is stretched to reset the slide plate 411. The slide plate 411 then causes the locking strip 412 to be locked into the slot 413 for fixation. The button 403 has several slots 407 on the side away from the connecting rod 2, and these slots 407 are evenly distributed on the button 403. The slot 407 increases the friction between the hand and the button 403, preventing slippage when the button 403 is pressed. Limiting rods 405 are fixedly connected to both ends of the extension rod 402, and these limiting rods 405 are slidably connected to the connecting rod 2. The limiting rods 405 limit the extension rod 402, preventing it from shifting during sliding and improving its stability. A telescopic rod 409 is fixedly connected inside the connecting slot 408, and is fixedly connected to the slide plate 411. A spring 410 is fitted onto the arc surface of the telescopic rod 409. The telescopic rod 409 limits the spring 410, preventing deformation during use and improving its lifespan.

[0034] In the embodiments of this utility model, please refer to Figure 1 and Figure 5The auxiliary structure 5 includes a limiting block 51, which is fixedly connected to the connecting rod 2. A rotating shaft 53 is rotatably connected to the inner wall of the limiting block 51. A connecting block 52 is fixedly connected to the arc surface of the rotating shaft 53. The connecting block 52 is fixedly connected to the handle 1. A knob 54 is slidably connected to one end of the rotating shaft 53. Several insert rods 57 are fixedly connected to the side of the button 403 near the limiting block 51. Several insertion holes 56 are opened on the side of the limiting block 51 near the insert rods 57. A tension spring 58 is sleeved on the arc surface of the rotating shaft 53. The two ends of the spring 410 are fixedly connected to the knob 54 and the limiting block 51, respectively. When adjusting the grip of the depth measuring device, pull the knob 54 to move it. The knob 54 stretches the tension spring 58, causing the insertion rod 57 to separate from the insertion hole 56. Then, move the handle 1 to move it, which in turn moves the connecting block 52. The connecting block 52 then moves the rotating shaft 53, which rotates on the inner wall of the limiting block 51. After moving to the appropriate angle, align the insertion rod 57 with the insertion hole 56, then release the knob 54. The tension spring 58 retracts, causing the insertion rod 57 to be inserted into the insertion hole 56 for fixation. The knob 54 has several auxiliary grooves 55 evenly distributed on its arc surface. The auxiliary grooves 55 increase the friction between the knob 54 and the hand, preventing slippage when rotating the knob 54. The rotating shaft 53 has a circular cross-section and is made of stainless steel. The stainless steel material can increase the service life of the shaft 53 and prevent the shaft 53 from rusting during use;

[0035] The working principle of the lifting depth sounder provided by this utility model is as follows: When it is necessary to adjust the length of the measuring device 3, the button 403 is pressed to move it. The button 403 drives the connecting rod 406 to move, the connecting rod 406 drives the slide plate 411 to move, the slide plate 411 drives the spring 410 to retract, the slide plate 411 slides on the inner wall of the connecting groove 408, the slide plate 411 drives the locking strip 412 to move, then the locking strip 412 separates from the locking groove 413, and then the extension rod 402 extends. The extension rod 402 drives the connecting rod 406 to slide on the inner wall of the sliding groove 401. Once the button 403 is released at the appropriate position, the spring 410 stretches, causing the slide plate 411 to reset. The slide plate 411 then engages the locking strip 412 into the slot 413 for fixation. The slot 407 increases the friction between the hand and the button 403, preventing slippage when the button 403 is pressed. The limiting rod 405 limits the extension rod 402, preventing it from shifting during sliding and improving its stability. The telescopic rod 409 limits the spring 410, preventing it from deforming during use and extending its lifespan.

[0036] When the grip of the depth measuring device needs to be adjusted, pull the knob 54 to move it. The knob 54 drives the tension spring 58 to stretch, and the knob 54 drives the insertion rod 57 to separate from the insertion hole 56. Then move the handle 1 to move it. The handle 1 drives the connecting block 52 to move, and the connecting block 52 drives the rotating shaft 53 to move. The rotating shaft 53 rotates on the inner wall of the limiting block 51. After moving to the appropriate angle, align the insertion rod 57 with the insertion hole 56, and then release the knob 54. The tension spring 58 retracts, driving the insertion rod 57 to be inserted into the insertion hole 56 for fixation. The auxiliary groove 55 can increase the friction between the knob 54 and the hand to prevent slippage when rotating the knob 54. The stainless steel material can increase the service life of the rotating shaft 53 and prevent the rotating shaft 53 from rusting during use.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
