Description

Technical Field

[0001] This utility model relates to the field of measurement and distance measurement technology, specifically to a novel measuring centering rod connector. Background Technology

[0002] Centering rods are crucial auxiliary tools in geological exploration (geophysical exploration), engineering surveying, and other fields. Existing centering rod connectors, when used in mountainous and forested areas like Sichuan and Chongqing, require frequent adjustments to the rod height to capture satellite signals, posing a significant challenge to the rod structure, especially the connector at the top. Mainstream GNSS equipment (integrated units) weighs approximately 1 kg, and under wind loads and rod tilting conditions, the connector experiences continuous bending and torsional loads. Traditional threaded connectors, employing a "double-ended screw" design, inherently suffer from short lever arms and thin screws, making them prone to loosening, detachment, or even breakage due to stress concentration and fatigue wear, potentially leading to the destruction of the expensive GNSS main unit. Utility Model Content

[0003] The purpose of this invention is to provide a novel measuring centering rod connector that solves the problem that common connectors on the market, under long-term alternating stress, first cause plastic deformation and wear of the aluminum alloy threads, eventually leading to breakage at the connection and damage to the GNSS host.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel measuring centering rod connector includes an upper adapter and a lower adapter cylinder. The upper adapter is located at the upper part of the connector, and the lower adapter cylinder is located at the lower part of the connector. The upper adapter and the lower adapter cylinder are integrally formed, and the outer wall of the upper adapter is threaded.

[0005] Furthermore, the lower adapter tube is provided with a cylindrical sleeve inside.

[0006] Furthermore, a friction-enhancing silicone sleeve is fitted onto the outer wall of the cylindrical sleeve.

[0007] The beneficial effects of this utility model are as follows: This application has a simple structure and is easy to use. By increasing the lever arm, it resists bending moment. The sleeve transfers the force point from the inside of the rod head to the outside, greatly increasing the lever arm resisting bending moment and significantly reducing the bending stress at the connection root. Simultaneously, it increases the area and disperses stress. The wrap-around design provides a large contact area, allowing pressure, tension, and torque to be evenly transmitted and dispersed, avoiding stress concentration. It has greater versatility, meeting the needs of all current measuring centering rod connectors on the market and satisfying the requirements of a wide range of users.

[0008] It abandons the traditional "clubhead bearing" approach and instead adopts "sleeve bearing" technology. A thicker, stronger 6061 aluminum alloy sleeve is tightly wrapped around the original centering clubhead to form a sturdy whole.

[0009] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0013] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Please see Figure 1 A novel measuring centering rod connector according to a preferred embodiment of this application includes an upper adapter 1 and a lower adapter cylinder 2. The upper adapter 1 is provided at the upper part of the connector, and the lower adapter cylinder 2 is provided at the lower part of the connector. The upper adapter 1 and the lower adapter cylinder 2 are integrally formed, and the outer wall of the upper adapter 1 is provided with threads.

[0018] The lower adapter tube 2 has a cylindrical sleeve 3 inside.

[0019] Example 2 Figure 2 In this embodiment, the structure is the same as in Example 1, but a friction-enhancing silicone sleeve 4 is fitted onto the outer wall of the cylindrical sleeve 3.

[0020] A thicker, stronger aluminum alloy sleeve is used, tightly wrapped around the original centering rod head and securely fixed with a flexible pin. When operating in mountainous and forested environments, the aluminum alloy sleeve significantly increases the lever arm against bending moments during frequent extension and retraction of the measuring rod. The increased contact area allows for more effective transmission and dispersion of pressure, tension, and torque on the rod head. This significantly reduces stress concentration at the connection point, preventing joint breakage and avoiding the risk of damage to the GNSS main unit.

[0021] In summary, this utility model provides a novel measuring centering rod connector. This device has a simple structure and is easy to use. By increasing the lever arm, it resists bending moments. The sleeve transfers the force point from the inside of the rod head to the outside, greatly increasing the lever arm resisting bending moments and significantly reducing bending stress at the connection root. Simultaneously, the increased area disperses stress. The wrap-around design provides a large contact area, allowing pressure, tension, and torque to be evenly transmitted and dispersed, avoiding stress concentration. It has greater versatility, meeting the needs of all measuring centering rod connectors currently on the market and satisfying the requirements of a wide range of users.

[0022] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0023] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
