Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts maintenance equipment technology, and more specifically, it relates to a high-efficiency nozzle fixture for use on steering wheels. Background Technology
[0002] As an important component of car driving, the steering wheel's operational flexibility and lifespan directly affect the driver's driving experience and road safety. To ensure the normal operation of the steering wheel and reduce wear and malfunctions, regular lubrication of the steering wheel switch parts is particularly important.
[0003] For example, the automotive steering wheel opening and closing hydration device disclosed in patent announcement number CN220287094U includes a base, a mounting seat and a bracket on the top of the base, a top seat on the top of the bracket, a cylinder on the top seat, a mounting plate on the bottom of the piston rod of the cylinder, a pump body on the top of the mounting plate, a first pipe connected to the output end of the pump body, a rotating box on the bottom end of the first pipe, a drive mechanism on the rotating box, a second pipe connected to the bottom end of the rotating box, and a nozzle on the bottom end of the second pipe.
[0004] In the above method, the nozzle is controlled by a cylinder to enter the switch slot. The rotatable nozzle sprays oil into the interior of the switch slot. However, due to the simple nozzle structure, when the switch slot structure is complex or has dead corners, the sprayed lubricating oil cannot evenly cover the inner wall of the switch slot.
[0005] Because the structure of the nozzle cannot be adjusted, the spraying area of the lubricating oil is the same for all nozzles, making it impossible to adjust the spraying area based on the structure of the switch slot. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-efficiency spray nozzle fixture for steering wheels that improves the uniformity of spraying and allows the spraying area of the nozzle to be adjusted according to the structure of the switch slot.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A high-efficiency spray nozzle fixture for a steering wheel includes a liquid supply assembly. The liquid supply assembly includes a connecting post and a plurality of first spray pipes that are connected to the outer wall of the connecting post. Each of the first spray pipes is in communication with the connecting post.
[0009] The connecting column is also equipped with several second spray pipes and several third spray pipes.
[0010] Both the second and third spray pipes are wrapped around the outer wall of the connecting column, and both are connected to the connecting column.
[0011] The first and second spray pipes are both placed inside the third spray pipe.
[0012] The first spray pipe is placed inside the second spray pipe.
[0013] The first, second, and third spray pipes are each equipped with several circular liquid outlets.
[0014] The second spray pipe is equipped with a first locking pipe that is detachably connected to the second spray pipe.
[0015] The third spray pipe is equipped with a second locking pipe that can be detachably connected to the second spray pipe.
[0016] The present invention is further configured such that the outlet of the third spray pipe is larger than the outlet of the second spray pipe and the outlet of the first spray pipe.
[0017] The present invention is further configured such that: a first receiving groove is provided on the second spray pipe, and there are two first receiving grooves; the outlet of the second spray pipe is located between the two first receiving grooves; a first plug-in ring is provided on the first locking pipe to cooperate with the first locking pipe; and the first plug-in ring is inserted into the first receiving groove.
[0018] The present invention is further configured such that: a second receiving groove is provided on the third spray pipe, there are two second receiving grooves, the liquid outlet of the third spray pipe is placed between the two second receiving grooves, and a second plug-in ring is provided on the second locking pipe, the second plug-in ring extends into the first receiving groove and is plugged into the first receiving groove.
[0019] The present invention is further configured such that the diameter of the third spray pipe is greater than the diameter of the second spray pipe, which is greater than the diameter of the first spray pipe.
[0020] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0021] Lubricating oil flows out from four first spray pipes, four second spray pipes, and four third spray pipes. The first, second, and third spray pipes are selected for oil spraying based on the internal area of the switch slot. The sprayed lubricating oil evenly covers the inner wall of the switch slot, thus improving spray uniformity. The first locking pipe can cover or expose the outlet of the second spray pipe, and the second locking pipe can cover or expose the outlet of the third spray pipe, allowing the spray area to be adjusted according to the structure of the switch slot. Because the outlets of the third spray pipes are all larger than the outlets of the second and first spray pipes, the spray area is further increased. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.
[0028] like Figs. 1 to 3 As shown, the high-efficiency nozzle fixture for the steering wheel includes a motor and a liquid supply assembly 1. The liquid supply assembly 1 includes a connecting post 2 and four first spray pipes 3 surrounding the outer wall of the connecting post 2. The output end of the motor is connected to the top surface of the connecting post 2. When the motor is run, it causes the connecting post 2 to rotate 90 degrees back and forth. The rotation of the connecting post 2 drives the rotation of the first spray pipes 3.
[0029] An oil reservoir is installed on the top surface of the connecting column 2, allowing lubricating oil to flow in and out of the first spray pipe 3. All four first spray pipes 3 are connected to the connecting column 2, ensuring that the lubricating oil flows out from each of the four pipes, providing four transmission paths and improving spraying efficiency.
[0030] The connecting column 2 is also equipped with four second spray pipes 4 and four third spray pipes 5. The second spray pipes 4 and the third spray pipes 5 are also connected to the outer wall of the connecting column 2. Lubricating oil can also flow out from the four second spray pipes 4 and the third spray pipes 5.
[0031] Meanwhile, the diameter of the third spray pipe 5 is larger than that of the second spray pipe 4, which is larger than that of the first spray pipe 3. The combination of the first spray pipe 3, the second spray pipe 4, and the third spray pipe 5 allows for oil spraying onto a large area inside the switch slot.
[0032] When spraying oil into the interior of a medium-sized switch slot, the second insert rings 12 on the two second locking tubes 7 can be inserted into the two corresponding second receiving slots 11 respectively. The second locking tubes 7 are locked in place within the second receiving slots 11. At this time, the third spray pipe 5 is covered, and lubricating oil will not spray out from the third spray pipe 5. When the second locking tube 7 is removed from the third spray pipe 5, the second locking tube 7 is pried outward, and the second insert rings 12 are pulled out from the second receiving slots 11, so that the second locking tube 7 is separated from the third spray pipe 5. The second insert rings 12 and the second locking tube 7 are integrally formed.
[0033] When spraying oil into the small area of the switch slot, the second locking tube 7 covers the third spray tube 5, and then the first insert ring 10 on the first locking tube 6 engages and fixes with the first receiving groove 9. At this time, the first locking tube 6 covers the second spray tube 4, preventing lubricating oil from flowing out of the second spray tube 4. The first insert ring 10 and the first locking tube 6 are integrally formed. There are two first insert rings 10 and two first receiving grooves 9, corresponding to each other. When the first locking tube 6 covers the second spray tube 4, prying the first locking tube 6 outward causes the first insert ring 10 to disengage from the first receiving groove 9, separating the first locking tube 6 from the second spray tube 4.
[0034] The outlet 8 of the third spray pipe 5 is larger than the outlet 8 of the second spray pipe 4 and the outlet 8 of the first spray pipe 3, so that the third spray pipe 5 can expand the spraying area of the lubricating oil.
[0035] Working principle: Lubricating oil flows out from four first spray pipes 3, four second spray pipes 4, and four third spray pipes 5. Based on the internal area of the switch slot, the first spray pipes 3, second spray pipes 4, and third spray pipes 5 are selected for oil spraying. The sprayed lubricating oil evenly covers the inner wall of the switch slot, thereby improving the uniformity of spraying. The first locking pipe 6 can cover or expose the outlet 8 on the second spray pipe 4, and the second locking pipe 7 can cover or expose the outlet 8 on the third spray pipe 5. Thus, the spraying area of the nozzle can be adjusted according to the structure of the switch slot.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
