Abstract

This utility model belongs to the technical field of spline nozzle holders, and particularly relates to a spline nozzle holder, comprising: a chassis, a spline sleeve fixedly mounted on the top of the chassis, an air hole at the center of the bottom of the chassis, and circular holes on both sides of the air hole at the bottom of the chassis; a through hole on the chassis; a cavity and a circular groove, both of which are formed inside the spline sleeve. Through the provided storage groove and two lubrication grooves, when the entire device is in use, the internal structure of the spline will come into contact with lubricating oil, thereby lubricating the internal structure of the spline. Furthermore, the internal structure of the spline generates frictional heat during movement, causing the lubricant to slowly condense into liquid and flow into various internal structures of the entire device, maintaining its optimal performance. Simultaneously, the chassis, spline sleeve, and spline cover ensure protection of the spline and its internal structure, preventing external machine oil from corroding the spline and its internal structure.

Description

Technical Field

[0001] This utility model belongs to the technical field of splined nozzle holders, and particularly relates to a splined nozzle holder. Background Technology

[0002] A spline nozzle mount is a mechanical connecting element typically used for securing nozzles or other components and transmitting power. Its structural design, utilizing a spline connection, provides a more robust connection and efficient torque transmission capability, making it widely applicable in liquid transport, air handling, and spraying equipment.

[0003] The core feature of the spline nozzle holder is its spline connection. A spline connection is a structure that transmits torque through a series of interlocking grooves and ridges, typically used in applications requiring torque transmission or preventing relative rotation between two components.

[0004] Current splines are prone to getting contaminated with machine oil during operation, leading to corrosion. Furthermore, splines require regular inspection and lubrication, but operators sometimes forget to apply lubricant, causing some splines to jam, become damaged, and lose performance. Therefore, we propose a spline nozzle holder. Utility Model Content

[0005] The purpose of this invention is to provide a splined nozzle holder to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a splined nozzle holder, comprising:

[0007] The chassis has a spline sleeve fixedly installed on its top, an air hole is opened at the center of the bottom of the chassis, and round holes are opened on both sides of the bottom of the chassis and on the chassis. A through hole is opened on the chassis.

[0008] The cavity and the circular groove are both formed inside the spline sleeve, and the cavity is connected to the air hole. A retaining key is provided in the cavity, and a fixing groove is formed in the retaining key. A spline is provided in the circular groove and on one side of the retaining key. A spline rod is provided in the spline, and one end of the spline rod passes through the spline and the retaining key. A fixing rod is provided in the spline rod.

[0009] The spline cover is disposed on the top of the spline sleeve and is fixed to the spline by several screws;

[0010] Two lubrication grooves are provided on the spline sleeve, and a storage groove is provided on the spline, the storage groove being connected to the two lubrication grooves.

[0011] In this technical solution, a storage tank and two lubrication tanks allow solidified lubricating oil to be rapidly injected into the storage tank, enabling long-term storage. When the entire device is in use, the internal structure of the spline comes into contact with the lubricating oil, which then lubricates the internal structure. Furthermore, the friction and heat generated during the movement of the internal structure cause the lubricating oil to slowly liquefy and flow into the various internal structures of the device. This ensures precise fit of the spline structure, reduces friction and wear between components, extends service life, and maintains optimal performance. Simultaneously, the chassis, spline sleeve, and spline cover protect the spline and its internal structure from external oil corrosion.

[0012] In the above technical solution, the cavity is further connected to the circular groove and the air hole, and the cavity is located between the circular groove and the air hole.

[0013] In this technical solution, one end of the spline rod and the fixing rod can be inserted into the air hole, and the fixing rod is a hollow tube to ensure that the gas can be discharged to the outside through the air hole and the fixing rod.

[0014] In the above technical solution, the chassis and spline sleeve are integrally formed, and the storage slot stores lubricating oil.

[0015] In this technical solution, the structural stability of the chassis and spline sleeve is ensured, the spline and its internal structure are protected, and external engine oil is prevented from corroding the spline and its internal structure. Meanwhile, the solidified lubricating oil in the storage tank lubricates the internal structure of the spline.

[0016] In the above technical solution, the spline rod and the fixing rod are integrally formed, and the spline rod is slidably connected to the spline, the fixing groove, and the air hole.

[0017] In this technical solution, the structural stability of the spline rod and the fixed rod is ensured, and the spline rod can slide in the spline, the fixed groove and the air hole.

[0018] In the above technical solution, further, the diameter of the spline is equal to that of the circular groove, and one end of the spline rod is equal to the diameter of the air hole.

[0019] In this technical solution, the spline can be seamlessly installed into the circular groove, making it easy for one end of the spline rod to be inserted into the air hole.

[0020] In the above technical solution, furthermore, the screw is connected to the spline cap and the spline thread.

[0021] In this technical solution, the screws are designed to securely fix the spline cover to the spline, thus providing protection for the spline.

[0022] The beneficial effects of this utility model are:

[0023] 1. This spline nozzle holder, through its storage tank and two lubrication tanks, allows solidified lubricating oil to be quickly injected into the storage tank via the two lubrication tanks. This allows the solidified lubricating oil to be stored in the storage tank for a long time. When the entire device is in use, the internal structure inside the spline will come into contact with the lubricating oil, thereby lubricating the internal structure inside the spline. Moreover, the internal structure inside the spline will generate heat through friction during movement, causing the lubricating oil to slowly turn into liquid and flow into the various internal structures of the entire device. This ensures the precise fit of the spline structure, reduces friction and wear between components, extends service life, and maintains its optimal performance.

[0024] 2. This spline nozzle holder, through its chassis, spline sleeve, and spline cover, ensures protection for the spline and its internal structure, preventing external machine oil from corroding the spline and its internal structure. Attached Figure Description

[0037] Cavity 21 and circular groove 22 are both formed inside spline sleeve 2, and cavity 21 is connected to air hole 13. A retaining key 3 is provided inside cavity 21, and a fixing groove 31 is formed inside retaining key 3. A spline 4 is provided inside circular groove 22 and on one side of retaining key 3. A spline rod 5 is provided inside spline 4, and one end of spline rod 5 passes through spline 4 and retaining key 3. A fixing rod 6 is provided inside spline rod 5.

[0038] The spline cover is located on top of the spline sleeve 2 and is fixed to the spline 4 by several screws 7.

[0039] Two lubrication grooves 23 are provided on the spline sleeve 2, and a storage groove is provided on the spline 4, which is connected to the two lubrication grooves 23.

[0040] The system incorporates a storage tank and two lubrication tanks 23, allowing solidified lubricating oil to be rapidly injected into the storage tank. This enables the lubricating oil to be stored for an extended period. During operation, the internal structure of the spline 4 comes into contact with the lubricating oil, which then lubricates this structure. Furthermore, the friction and heat generated during the movement of the internal structure of the spline 4 cause the lubricating oil to slowly liquefy and flow into the various internal components of the device. This ensures precise fit of the spline 4 structure, reduces friction and wear between components, extends service life, and maintains optimal performance. Simultaneously, the chassis 1, spline sleeve 2, and spline cover protect the spline 4 and its internal structure from external oil corrosion.

[0041] Example 2: This example provides a spline nozzle holder, which, in addition to the technical solutions of the above examples, also has the following technical features: the cavity 21 is connected to the circular groove 22 and the air hole 13, and the cavity 21 is located between the circular groove 22 and the air hole 13.

[0042] The spline rod 5 and the fixing rod 6 are designed so that one end can be inserted into the vent 13, and the fixing rod 6 is a hollow tube to ensure that gas can be discharged to the outside through the vent 13 and the fixing rod 6.

[0043] Example 3: This example provides a splined nozzle holder, which, in addition to the technical solutions of the above examples, also has the following technical features: the chassis 1 and the splined sleeve 2 are integrally formed structures, and the storage groove stores lubricating oil.

[0044] Specifically, this ensures the structural stability of the chassis 1 and spline sleeve 2, protects the spline 4 and its internal structure, and prevents external engine oil from corroding the spline 4 and its internal structure; while the solidified lubricating oil in the storage tank lubricates the internal structure of the spline 4.

[0045] Example 4: This example provides a spline nozzle holder, which, in addition to the technical solutions of the above examples, also has the following technical features: the spline rod 5 and the fixing rod 6 are integrally formed, and the spline rod 5 is slidably connected to the spline 4, the fixing groove 31, and the air hole 13.

[0046] This ensures the structural stability of the spline rod 5 and the fixed rod 6, and ensures that the spline rod 5 can slide in the spline 4, the fixed groove 31 and the air hole 13.

[0047] Example 5: This example provides a spline nozzle holder, which, in addition to the technical solutions of the above examples, also has the following technical features: the diameter of the spline 4 is equal to that of the circular groove 22, and one end of the spline rod 5 is equal to the diameter of the air hole 13.

[0048] This ensures that the spline 4 can be seamlessly installed into the circular groove 22, making it convenient for one end of the spline rod 5 to be inserted into the air hole 13.

[0049] Example 6: This example provides a spline nozzle holder, which, in addition to the technical solutions of the above examples, also has the following technical features: the screw 7 is threadedly connected to the spline cover and the spline 4.

[0050] Among them, screw 7 ensures that the spline cover can be stably fixed on spline 4, and ensures that spline 4 can be shielded and protected.

[0051] Working principle:

[0052] Solidified lubricating oil is rapidly injected into the storage tank through two lubrication grooves 23, allowing it to be stored for an extended period. During operation, the internal structure of spline 4 comes into contact with the lubricating oil, which then lubricates it. Furthermore, the friction and heat generated during the movement of the internal structure of spline 4 cause the lubricating oil to slowly liquefy and flow into the various internal structures of the device. This ensures precise fit of the spline 4 structure, reducing friction and wear between components, extending service life, and maintaining optimal performance. Simultaneously, the chassis 1, spline sleeve 2, and spline cover protect the spline 4 and its internal structure from external oil corrosion.
