Description

Technical Field

[0001] This utility model relates to the field of guide sleeve technology, specifically to a split threaded guide sleeve. Background Technology

[0002] Threaded guide sleeves are important components used in hydraulic support columns. They have specific structures and functions, connecting to the cylinder or other parts via threads. This connection method makes installation and removal of the guide sleeve relatively convenient. To ensure good sealing, threaded guide sleeves are typically equipped with O-rings and retaining rings. These seals are located on the outer or inner circumference of the guide sleeve to prevent fluid leakage.

[0003] A type of embedded threaded guide sleeve structure, disclosed in CN208764034U, is fitted onto the outside of a piston rod. It includes a cylinder and a threaded guide sleeve. The cylinder has a fluid passage hole, an internal thread, and a retaining ring groove. The internal thread is located on one side of the fluid passage hole, and the end face of the internal thread away from the fluid passage hole is stepped. An elastic retaining ring is provided in the retaining ring groove. An O-ring and a sealing retaining ring are provided on the outer circumference of the threaded guide sleeve. From the left end face to the right end face of the guide sleeve, a piston rod sealing ring, a guide ring, and a dustproof ring are sequentially provided on the inner circumference of the threaded guide sleeve. This design is easy to disassemble, has a simple structure, and ensures structural stability after assembly with the cylinder, preventing loosening or detachment. Furthermore, it improves material utilization in guide sleeve production and reduces labor costs.

[0004] While the existing technology CN208764034U has many advantages in use, it still has the following problems: its disassembly efficiency for the guide sleeve is not perfect. As a result, when disassembling and maintaining the outer sealing ring, only the entire guide sleeve can be removed, which will cause leakage of liquid inside the cylinder, thus resulting in low disassembly efficiency of the guide sleeve. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a split threaded guide sleeve.

[0006] The technical solution adopted by this utility model to solve its technical problem is a split threaded guide sleeve, including a cylinder, an annular plate, a receiving groove and a guide rod. The guide sleeve body is provided on one side of the upper end of the cylinder. A sealing mechanism is provided on the inner wall of the guide sleeve body. An annular plate is provided on the outer wall of the lower end of the guide sleeve body. Fitting grooves are provided on both sides of the upper outer wall of the annular plate and both sides of the lower outer wall of the guide sleeve body. An annular sealing ring is provided inside the fitting groove.

[0007] By adopting the above technical solution, the annular sealing ring and the fitting groove can ensure the sealing between the annular plate and the guide sleeve body, thereby ensuring the sealing after the annular plate and the guide sleeve body are connected, so that the annular plate and the guide sleeve body form a complete guiding mechanism, and the sealing mechanism can ensure the sealing between the guide sleeve body and the guide rod.

[0008] Specifically, a guide rod is provided inside the guide sleeve body and the annular plate, and the upper end of the guide rod protrudes from the guide sleeve body.

[0009] By adopting the above technical solution, the guide rod creates a stable guiding structure between the guide sleeve body and the annular plate, which can effectively guide and support the moving parts. At the same time, the upper end of the guide rod protrudes from the guide sleeve body, which facilitates connection and transmission with external mechanisms, improving the flexibility and practicality of the entire device.

[0010] Specifically, the sealing mechanism consists of a dustproof ring, a guide ring, a sealing retaining ring, and a leakage prevention barrier ring. The dustproof ring, guide ring, sealing retaining ring, and leakage prevention barrier ring are embedded and installed from top to bottom inside the guide sleeve body, and the inner rings of the dustproof ring, guide ring, sealing retaining ring, and leakage prevention barrier ring are in contact with the outer wall of the guide rod.

[0011] By adopting the above technical solution, these components of the sealing mechanism are embedded and installed from top to bottom inside the guide sleeve body, forming multiple protective layers. This design can effectively prevent dust, liquids, and other impurities from entering the guide sleeve body, ensuring the sealing and cleanliness of the guide sleeve body, thereby extending its service life.

[0012] Specifically, the guide sleeve body has a circular array of blind holes inside, and a storage groove is provided at the lower end of the inner wall of the blind holes, with the lower end of the inner wall of the storage groove having a through-type design.

[0013] By adopting the above technical solution, the blind hole not only increases the strength and stability of the guide sleeve, but also provides installation space for external fasteners and bolts. The through-hole design at the lower end of the inner wall of the receiving groove allows bolts to easily pass through and fix the annular plate, improving the connection firmness of the entire device.

[0014] Specifically, the outer wall of the guide sleeve body is provided with threads, and the threads are threaded to the inner wall of the cylinder.

[0015] By adopting the above technical solution, the threaded connection enables the quick installation and disassembly of the guide sleeve body. This connection method is not only simple and convenient to operate, but also ensures a tight fit between the guide sleeve body and the cylinder, improving the stability and sealing of the entire device. Furthermore, the disassembly of the guide sleeve body is carried out after the bolts are removed.

[0016] Specifically, the outer wall of the upper end of the annular plate is threaded with bolts arranged in a circular array, and the heads of the bolts are located inside the receiving groove.

[0017] By adopting the above technical solution, the bolt and the receiving groove can connect the guide sleeve body and the annular plate, ensuring the stability of the connection between the guide sleeve body and the annular plate. The bolt not only plays the role of fixing the annular plate, but also achieves the hidden installation of the bolt by designing its head inside the receiving groove.

[0018] Specifically, the inner wall of the annular plate is provided with an inner sealing ring, and both sides of the outer wall of the annular plate are provided with outer sealing rings.

[0019] By adopting the above technical solution, the inner sealing ring contacts the outer wall of the guide rod, ensuring the sealing between the guide rod and the annular plate; the outer sealing ring contacts the inner wall of the cylinder, ensuring the sealing between the annular plate and the inner wall of the cylinder.

[0020] The beneficial effects of this utility model are:

[0021] (1) The split threaded guide sleeve described in this utility model constitutes a compact, easy-to-install and maintain split threaded guide sleeve body. This design not only improves the stability and durability of the guide sleeve body, but also facilitates subsequent maintenance and replacement work.

[0022] (2) The split threaded guide sleeve of this utility model can ensure that the annular plate remains inside the cylinder when the guide sleeve body is disassembled, and can still ensure the sealing between the cylinder and the guide rod, avoiding leakage inside the cylinder when the sealing mechanism is maintained, and improving the maintenance efficiency of the guide sleeve body.

An annular sealing ring 25 is provided inside the fitting groove 24.

[0031] In use, the annular sealing ring 25 and the fitting groove 24 can ensure the sealing between the annular plate 2 and the guide sleeve body 11, thereby ensuring the sealing after the annular plate 2 and the guide sleeve body 11 are connected, so that the annular plate 2 and the guide sleeve body 11 form a complete guide mechanism, and the sealing mechanism 12 can ensure the sealing between the guide sleeve body 11 and the guide rod 16.

[0032] To assemble guide rod 16, for example, as follows: Figure 2 As shown, a guide rod 16 is provided inside the guide sleeve body 11 and the annular plate 2, and the upper end of the guide rod 16 protrudes from the guide sleeve body 11.

[0033] In use, the guide rod 16 forms a stable guiding structure between the guide sleeve body 11 and the annular plate 2, which can effectively guide and support the moving parts. At the same time, the upper end of the guide rod 16 protrudes from the guide sleeve body 11, which facilitates connection and transmission with external mechanisms, improving the flexibility and practicality of the entire device.

[0034] For sealing, exemplarily, such as Figure 3 As shown, the sealing mechanism 12 consists of a dustproof ring, a guide ring, a sealing ring, and a leakage-proof barrier ring. The dustproof ring, guide ring, sealing ring, and leakage-proof barrier ring are embedded and installed from top to bottom inside the guide sleeve body 11, and the inner rings of the dustproof ring, guide ring, sealing ring, and leakage-proof barrier ring are in contact with the outer wall of the guide rod 16.

[0035] During use, these components of the sealing mechanism 12 are embedded from top to bottom inside the guide sleeve body 11, forming multiple protective layers. This design effectively prevents dust, liquids, and other impurities from entering the guide sleeve body 11, ensuring the sealing and cleanliness of the guide sleeve body 11, thereby extending its service life.

[0036] For connection purposes, exemplified, such as Figure 1 As shown, the guide sleeve body 11 has blind holes 13 arranged in a circular array inside, and a storage groove 15 is provided at the lower end of the inner wall of the blind hole 13. The lower end of the inner wall of the storage groove 15 adopts a through-type design.

[0037] In use, the blind hole 13 not only increases the strength and stability of the guide sleeve body 11, but also provides installation space for external fasteners and bolts 22. The through-hole design at the lower end of the inner wall of the receiving groove 15 allows the bolts 22 to easily pass through and fix the annular plate 2, improving the connection firmness of the entire device.

[0038] For threaded connections, exemplarily, such as Figure 3 As shown, the outer wall of the guide sleeve body 11 is provided with threads 14, and the threads 14 are threadedly connected to the inner wall of the cylinder 1.

[0039] During use, the thread 14 enables quick installation and disassembly of the guide sleeve body 11.

Furthermore, the disassembly of the guide sleeve body 11 is carried out after the bolt 22 is removed.

[0040] For fixed connections, for example, such as Figure 4 As shown, the outer wall of the upper end of the annular plate 2 is threaded with bolts 22 arranged in a circular array, and the head of the bolts 22 is located inside the receiving groove 15.

[0041] In use, the bolt 22, together with the storage groove 15, enables the connection between the guide sleeve body 11 and the annular plate 2, ensuring the stability of the connection between the guide sleeve body 11 and the annular plate 2. The bolt 22 not only serves to fix the annular plate 2, but also achieves a hidden installation by having its head located inside the storage groove 15.

[0042] For sealing, exemplarily, such as Figure 4 As shown, an inner sealing ring 21 is provided on the inner wall of the annular plate 2, and outer sealing rings 23 are provided on both sides of the outer wall of the annular plate 2.

[0043] During use, the inner sealing ring 21 contacts the outer wall of the guide rod 16, ensuring the sealing between the guide rod 16 and the annular plate 2. The outer sealing ring 23 contacts the inner wall of the cylinder 1, ensuring the sealing between the annular plate 2 and the inner wall of the cylinder 1.

[0044] When using this utility model, the annular plate 2 is installed inside the cylinder 1 to ensure that the two sides of the upper outer wall of the annular plate 2 and the two sides of the lower outer wall of the guide sleeve body 11 are aligned, and an annular sealing ring 25 is installed in the fitting groove 24 to ensure the sealing between the annular plate 2 and the guide sleeve body 11.

[0045] Following the order of dustproof ring, guide ring, sealing ring, and leak-proof barrier ring, the components are embedded and installed from top to bottom into the inner wall of the guide sleeve body 11, ensuring that the inner rings of these components can subsequently make close contact with the outer wall of the guide rod 16. The guide rod 16 is then passed through the guide sleeve body 11, ensuring that the upper end of the guide rod 16 protrudes a certain distance from the guide sleeve body 11 for subsequent connection with external mechanisms.

[0046] Align the threads 14 on the outer wall of the guide sleeve body 11 with the threads on the inner wall of the cylinder 1, rotate the guide sleeve body 11 until it is tightly connected to the cylinder 1, and thread the bolts 22 distributed in a circular array on the upper outer wall of the annular plate 2, ensuring that the head of the bolt 22 is inside the receiving groove 15 to achieve hidden installation. At the same time, the annular plate 2 is further fixed to the guide sleeve body 11 by the bolts 22.
