Description

Technical Field

[0001] This utility model belongs to the technical field of threaded sleeves, and in particular relates to a threaded sleeve with internal and external anti-loosening teeth. Background Technology

[0002] A thread insert is a fastening element embedded inside a part to repair or reinforce internal threads. Its core function is to act as a robust thread bushing. The most common type is the wire thread insert, which is made of stainless steel wire wound into a spring shape. It can significantly improve thread strength, wear resistance, and anti-loosening and shock resistance, and is especially suitable for soft metals such as aluminum and magnesium. Another major category is the self-tapping thread insert, which can tap the base material itself during installation without pre-tapping. It is very suitable for plastics and soft materials. In addition, there are integrally machined nests used to provide strength conversion or change thread specifications. However, thread inserts still have the following drawbacks in practical use: When the threaded insert is in use, it is directly rotated and transported to the original installation equipment in the base body, and then the bolt is installed. However, when installing the threaded insert, if the operator manually screws it in, the tightening force will not be large enough, which will affect the tightness of the tightening. Secondly, in order to carry out internal and external anti-loosening operations, the thread directions of the inner and outer threads of the threaded sleeve need to be set to opposite directions. During the installation of the threaded sleeve, the bolt directly enters into it. When rotating the bolt, the tightening torque needs to be strictly controlled, which makes it inconvenient to install the bolt inside the threaded sleeve. Utility Model Content

[0003] The purpose of this utility model is to provide an internal and external anti-loosening toothed threaded sleeve. By setting a fixed cylinder, connecting cylinder, fastening component, clamping ring and bottom fixing plate, it solves the problems that the tightening force is not large enough due to the need for operators to manually screw in the threaded sleeve during installation, which affects the tightening degree. In addition, the installation operation of the threaded sleeve requires more precise torque, which is not convenient.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an internal and external anti-loosening toothed threaded sleeve, comprising a fixed cylinder, a connecting cylinder, a fastening assembly, a clamping ring, and a bottom fixing plate. The bottom fixing plate is fixed to the bottom end of the fixed cylinder, and the connecting cylinder is fixed to the top end of the fixed cylinder. A fastening assembly is fixed to the upper edge of the periphery of the connecting cylinder. The fastening assembly includes an inner mounting ring, and a clamping ring is fixed to the bottom end of the inner mounting ring. The clamping ring is fixed to the periphery of the connecting cylinder. The bottom end of the fixed cylinder is connected to the bottom fixing plate, and the top end is fixed to the connecting cylinder. A fastening assembly is provided on the upper periphery of the connecting cylinder. The bottom end of the inner mounting ring of this assembly is connected to the clamping ring, and the clamping ring is fixed to the periphery of the connecting cylinder to achieve clamping and fixing with the base.

[0005] Furthermore, an internal thread is fixed on the inner wall of the fixed cylinder, and an external thread is fixed on the periphery of the fixed cylinder. The internal thread and the external thread have opposite helical directions. The inner wall of the fixed cylinder is provided with an internal thread, and the outer side is provided with an external thread. The two have opposite helical directions. The internal thread is used to connect the mounting bolt, and the external thread is used to connect with the mounting hole of the base body by thread, so as to achieve bidirectional fastening.

[0006] Furthermore, a connecting ring is fixed to the top of the connecting cylinder, and the connecting ring has a continuous annular array of serrations on its circumference. The connecting cylinder has a connecting ring at its top, and the connecting ring has a annular array of serrations on its circumference. Rotating the serrations can drive the fixed cylinder to rotate, facilitating the screwing of the external thread into the mounting hole of the base.

[0007] Furthermore, the fastening assembly also includes a guide ring and an annular groove. A guide ring is fixed to the circumference of the inner mounting ring. The top ends of both the inner mounting ring and the guide ring are fixed to the bottom end of the connecting ring. An annular groove is formed at the bottom end of the inner mounting ring. The fastening assembly also includes a guide ring and an annular groove. The guide ring is fixed to the circumference of the inner mounting ring, its top end connects to the connecting ring, and its bottom end has an annular groove for installing a fixing ring, thus securing the clamping ring.

[0008] Furthermore, a fixing ring is fixed to the top of the clamping ring, and the fixing ring is fixed in the annular groove. The outer diameter of the clamping ring is equal to the outer diameter of the inner mounting ring. The clamping ring is provided with a fixing ring at the top of the clamping ring, and the fixing ring is embedded in the annular groove so that the outer diameter of the clamping ring and the inner mounting ring are consistent, ensuring that the clamping ring is tightly fitted to the base and enhancing the installation stability.

[0009] Furthermore, the bottom fixing plate is arranged vertically and horizontally, and a flexible ring is fixed at the top of the bottom fixing plate. The flexible ring is set inside the fixing cylinder. The bottom fixing plate has a through structure, and the flexible ring at the top is placed inside the fixing cylinder. When the mounting bolt is screwed in, it is pressed against the flexible ring to improve the tightness of the bolt and prevent loosening.

[0010] This utility model has the following beneficial effects: This invention solves the problem of insufficient tightening force caused by manual screwing during the installation of threaded sleeves by setting up a fixed sleeve and a connecting sleeve. When the fixed sleeve needs to be installed, the bottom end of the fixed sleeve is aligned with the mounting hole on the mounting base. By rotating the toothed part of the wrench, the external thread on the outside of the fixed sleeve is screwed into the mounting hole of the base and tightened. At this time, the bolt for installation can be inserted into the connecting sleeve and screwed into the internal thread on the inner wall of the fixed sleeve. The internal thread is threadedly connected with the bolt for installation, and the installation is secured. This allows the tightening force to be guaranteed by using a wrench during the installation of the threaded sleeve.

[0011] This invention solves the problems of requiring more precise torque and inconvenient installation operations when installing threaded sleeves by setting up a fixed cylinder, connecting cylinder, fastening components, clamping ring, and bottom fixing plate. When the spline teeth rotate, they drive the external threads on the periphery of the fixed cylinder to screw into the mounting base. After installation, the clamping ring on the periphery of the connecting cylinder presses against the base, ensuring a tight seal between the base and the connecting ring and preventing the fixed cylinder from loosening during bolt installation. For bolt installation, the bolt is inserted into the connecting cylinder and screwed into the internal threads of the fixed cylinder until it is secured to the flexible ring at the top of the bottom fixing plate. This increases the tightness of the bolt installation, reduces the risk of loosening, and allows for a wider range of applicable torques during bolt installation, making the installation operation more convenient.
