Description

Technical Field

[0001] This utility model belongs to the field of measurement technology, specifically relating to an adjustable measuring rod length locking device. Background Technology

[0002] In surveying engineering and related applications, measuring rods are commonly used auxiliary tools for measuring height, distance, and angles. Traditional measuring rods are mostly fixed-length structures, or while they may have some adjustment capabilities, they lack an effective locking device after length adjustment. This leads to slippage or displacement during use, affecting measurement accuracy and operational safety. Therefore, a reasonably structured and easy-to-operate adjustable measuring rod length locking device is needed to achieve rapid adjustment and reliable fixation, improving the efficiency and accuracy of measurement work.

[0003] In existing technologies, the installation of traditional measuring rods often lacks sufficient stability. If the sensors or other measuring devices installed on them become loose or shift in position, it will not only affect the measurement accuracy, but may also fall off unexpectedly under vibration or external force. Once the equipment falls, it may not only cause physical damage to the instrument itself, but also pose a safety hazard to people or objects below, affecting work safety and efficiency.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This embodiment of the present invention provides an adjustable measuring rod length locking device, comprising:

[0026] The load-bearing mechanism 100 includes a fastener 101;

[0027] The fixing mechanism 200 includes a fastening component 201 disposed on the surface of the fixing member 101, and a locking component 202 disposed on one side of the fastening component 201.

[0028] Specifically, the fastener 101 includes a telescopic rod 1011 and a handle 1012 fixedly installed at the bottom of the telescopic rod 1011.

[0029] It should be noted that the telescopic rod 1011 can be adjusted in length along its axial direction to adapt to different usage scenarios or user needs, thereby improving the applicability and flexibility of the load-bearing mechanism.

[0030] Specifically, the fastening assembly 201 includes a fixing sleeve 2011 sleeved on the outer surface of the telescopic rod 1011, and a fastening bolt 2012 rotatably connected to the surface of the fixing sleeve 2011.

[0031] It should be noted that the fastening assembly 201 is used to fix external equipment or other functional components to the telescopic rod 1011. The position is locked and fixed by rotating the fastening bolt 2012 to ensure stable and reliable installation.

[0032] Specifically, the locking component 202 includes a sleeve 2021 fitted onto the surface of the fixed sleeve 2011, and a locking bolt 2022 rotatably connected to the surface of the sleeve 2021.

[0033] It should be noted that the locking component 202 is used to further restrict the movement of the fastening component 201 on the telescopic rod 1011, preventing loosening due to external vibration or accidental contact, thereby improving the safety and reliability of the overall structure.

[0034] Specifically, the inner surface of the fixing sleeve 2011 is fitted to the outer surface of the telescopic rod 1011, and the surface of the fixing sleeve 2011 is provided with threaded holes for use with the fastening bolt 2012.

[0035] It should be noted that the inner wall of the fixing sleeve 2011 fits tightly against the outer wall of the telescopic rod 1011 to ensure that the fastening assembly 201 can maintain a certain stability when it is not locked. At the same time, the threaded hole on its surface is precisely positioned to ensure that the fastening bolt 2012 can be effectively screwed in and pressure applied.

[0036] Specifically, the ferrule 2021 is fitted to the surface of the fixing sleeve 2011, and the surface of the ferrule 2021 has a threaded hole for use with the locking bolt 2022.

[0037] It should be noted that the sleeve 2021 and the fixing sleeve 2011 are connected by a fitting. The locking bolt 2022 passes through the threaded hole on its surface and abuts against the fixing sleeve 2011, thereby achieving secondary locking of the fastening component 201 and enhancing the overall structural strength.

[0038] In use, first adjust the length of the telescopic rod 1011 according to actual needs to adapt to different heights or distances. The handle 1012 is designed to ensure that the user can hold and adjust the telescopic rod securely. The anti-slip material and texture increase the safety and comfort of operation. When it is necessary to install external equipment or other functional components, place these components in the appropriate position and then fix them using the fastening component 201. Specifically, first, put the fixing sleeve 2011 on the outer surface of the telescopic rod 1011, ensuring that its inner surface is completely in contact with the outer surface of the telescopic rod. Then, rotate the fastening bolt 2012 to pass it through the threaded hole on the surface of the fixing sleeve and apply pressure to the external equipment to be fixed, achieving initial fixation. To further enhance stability and prevent loosening due to external vibration or accidental contact, the locking component 202 is then used. The ferrule 2021 is also fitted onto the surface of the fixing sleeve 2011 and fits tightly against it. Then, the locking bolt 2022 is rotated so that it is screwed into the threaded hole on the surface of the ferrule and abuts against the fixing sleeve, thereby implementing a secondary locking of the fastening components. This ensures that the entire structure can maintain a high degree of stability and safety in various application environments, and can effectively meet the diverse needs of users, whether for temporary installation or long-term deployment.

[0039] In summary, the dual locking mechanism of fastening component 201 and locking component 202 effectively ensures the stability and reliability of the external equipment installation, prevents loosening caused by external vibration or misoperation, avoids accidental equipment detachment, and improves the safety and stability of equipment use.
