Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to a fixing device for a portable handheld depth sounder. Background Technology

[0002] A fixing device is a mechanical or structural component used to stably fix an object in a specific position or state to prevent it from moving, loosening, falling off or deforming. A fixing device for a portable handheld depth sounder is an auxiliary device specifically designed for the stable installation, positioning or carrying of the handheld depth sounder. It aims to ensure that the depth sounder remains stable in a dynamic environment and avoid measurement errors or equipment damage caused by shaking, tilting or falling off.

[0003] Existing fixing devices are mostly of a single specification, and some use fasteners, straps, or other methods of fixation, which lack sufficient stability. During measurement, factors such as water flow impact can cause measurement data deviations, resulting in the inability to read the data. Utility Model Content

[0004] The purpose of this invention is to provide a fixing device for a portable handheld depth sounder, in order to solve the defect that the existing fixing devices for handheld depth sounders are not easy to connect securely.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fixing device for a portable handheld depth sounder, including a handheld rod;

[0006] The handheld handle has a telescopic rod inside, and a fixing structure is fixed to the top of the telescopic rod. The fixing structure includes a fixing nut fixed to the top of the telescopic rod. The fixing nut has a first threaded groove inside, and a screw is installed inside the first threaded groove. A connecting block is installed at the top of the fixing nut, and a fixing plate is fixed at the top of the connecting block. An installation nut is installed on the outside of the screw at the top of the fixing plate. A through hole is provided on the side of the fixing plate away from the screw.

[0007] A locking structure is provided on the outer side of the telescopic rod at the top of the handheld handle, and a rubber sleeve is provided on the outer side of the bottom of the handheld handle.

[0008] Preferably, the first threaded groove is threadedly connected to the screw, the connecting block is threadedly connected to the screw, the top end of the screw extends through the interior of the fixing plate to the top end of the fixing plate, and the screw is threadedly connected to the mounting nut.

[0009] With the above structure, the handle and the fixing parts are connected by screws and nuts during use, which makes the connection stable and easy to install.

[0010] Preferably, the fixing plates on both sides of the screw are of different lengths, and the two sides of the fixing plates are set at an angle.

[0011] Preferably, the locking structure includes a sliding groove disposed inside the hand handle, a fixing block fixed to the top of the hand handle, a retaining ring fixed to the top of the fixing block, a locking piece fixed to the top of the fixing block, a locking sleeve installed on the outside of the fixing block, a locking groove disposed at the top of the inside of the locking sleeve, and a second threaded groove disposed at the bottom of the inside of the locking sleeve.

[0012] Preferably, the telescopic rod and the hand handle are slidably connected by a groove, the outer side of the fixing block is provided with an external thread that matches the second thread groove, and the fixing block and the locking sleeve are threadedly connected by the second thread groove.

[0013] With the above structure, the telescopic rod can slide smoothly up and down along the inside of the hand handle during use, thereby quickly adjusting the overall length of the device. When the telescopic rod is adjusted to the required length, rotating the locking sleeve will cause the threaded drive to move the locking sleeve axially along the fixed block, thereby squeezing the locking plate to contract and press it tightly against the outer wall of the telescopic rod. Through friction, the telescopic rod is firmly locked in the current position, preventing the length from changing on its own due to external force during the measurement process, and ensuring measurement stability.

[0014] Preferably, the locking plates are evenly distributed at the top of the fixing block, the outer side of the locking plates is inclined, and the inner diameter of the top of the locking sleeve is smaller than the inner diameter of the bottom of the locking sleeve.

[0015] With the above structure, during use, the inclined surface of the locking plate and the conical inner wall of the locking sleeve make inclined contact, and the friction is evenly distributed. When rotating the locking sleeve, the relative movement of the two is smoother and avoids jamming.

[0016] The present invention provides a fixing device for a portable handheld depth sounder, the advantages of which are:

[0017] By incorporating a fixed structure and using threaded connections of components such as fixing nuts, screws, and mounting nuts, the fixing plate can be firmly secured to the telescopic rod. The threaded connection provides excellent stability for the fixing plate, ensuring a secure and easy installation. Combined with through holes, it allows for a tight fixation of the depth sounder, further enhancing the securing effect.

[0018] With a locking mechanism, the telescopic rod can slide up and down via a groove inside the handheld rod. Once adjusted to the appropriate length, rotating the locking sleeve locks it in place using the friction between the locking plate and the outer wall of the telescopic rod. This allows the device to meet the measurement needs of waters of varying depths. It satisfies the height requirements of portable handheld depth sounders on different vessels and can be used in various water bodies, improving the device's versatility and practicality.
