Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of telescopic structures for nozzles, and particularly relates to a telescopic structure for nozzles. Background Technology
[0002] Common water features typically employ multiple water jets to create a variety of water shapes. For example, direct jets can form crystal-clear, sharply defined water columns, while ice tower jets can spray out bold, upright water columns that fall around the top, resembling ice towers or cedar trees. Other jets can cause the water to spread out in fan, trumpet, or dandelion shapes. These water shapes, whether strong or gentle, high or low, dance on the water's surface, adding a rich dynamic aesthetic to the landscape.
[0003] Conventional sprinkler heads typically need to be exposed above the water surface to produce the desired water shape and jet. When the sprinklers are not in use, having many exposed heads detracts from the pool's aesthetics. Furthermore, if the water level is the same but the distance between the pool bottom and the surface varies, the tips of the sprinkler heads will be at different heights after the expansion joints are fully extended, resulting in uneven surfaces and affecting the overall appearance. Therefore, we propose a telescopic structure for the sprinkler heads. Utility Model Content
[0004] The purpose of this invention is to provide a telescopic structure for a nozzle to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a telescopic structure for a nozzle, comprising:
[0006] A sleeve, in which a core is slidably installed, and a threaded connector is fixedly installed at the top of the core. A threaded groove is opened on the circumference of the sleeve and at its upper end, and an outer cylinder is threadedly installed on the threaded groove.
[0007] A limiting groove is formed on the periphery of the core sleeve. A magnet is fixedly installed in the limiting groove. A stainless steel flat key is provided in the limiting groove and on one side of the magnet. An internal hexagon bolt is threaded on the periphery of the outer cylinder. One end of the internal hexagon bolt extends through the periphery of the outer cylinder into the limiting groove and is fixedly installed with a limiting block.
[0008] In this technical solution, when the sleeve moves up and down, the sleeve will drive the limiting groove to move during the movement, so that the limiting block slides in the limiting groove. At the same time, under the limiting of the limiting block and the limiting groove, it can be ensured that the sleeve will not rotate during the movement, thereby enhancing the stability of the sleeve during the movement.
[0009] When encountering a pool with a uniform water level but an uneven bottom, it's necessary to adjust the extension height of different sleeves. A hex wrench can be used to turn the internal hex bolt. The threaded movement causes the bolt to move outwards on the outer cylinder, simultaneously rotating and moving the limiting block until it disengages from the limiting groove. At this point, the limiting block releases the outer cylinder, allowing the operator to rotate it out of the threaded groove. Then, by moving the outer cylinder upwards, the operator can remove the stainless steel key from the limiting groove. Then, replace the stainless steel flat key with one of appropriate length. Place the stainless steel flat key of appropriate length into the bottom of the limiting groove. At this time, the stainless steel flat key will be attracted to the magnet, ensuring that the stainless steel flat key will not fall off without external force. Then, the personnel put the outer cylinder back into the threaded groove and turn the internal hex bolt again so that the limiting block enters into the limiting groove and abuts against the top of the stainless steel flat key. This ensures that it is easy for personnel to replace stainless steel flat keys of different lengths, thereby adjusting the distance between the top of the stainless steel flat key and the top of the limiting groove, so as to control the length of the sleeve extension.
[0010] In the above technical solution, the sleeve core is located inside the outer cylinder, and the inner wall of the outer cylinder is in contact with the periphery of the sleeve core.
[0011] In this technical solution, the structural stability of the core and the outer cylinder is ensured.
[0012] In the above technical solution, the stainless steel flat key is further magnetically connected to the magnet, and the stainless steel flat key is located at the bottom of the limiting groove.
[0013] In this technical solution, it is ensured that the stainless steel flat key can be attracted to the magnet, and that the stainless steel flat key will not easily fall off without the action of external force, thus ensuring the structural stability of the stainless steel flat key.
[0014] In the above technical solution, the limiting block is further connected to the limiting groove, and the periphery of the limiting block is in contact with the inner wall of the limiting groove.
[0015] In this technical solution, it is ensured that the limiting block can rotate and slide normally within the limiting groove, and that the limiting block and the limiting groove can limit the movement of the sleeve core, thus ensuring the stability of the sleeve core during movement.
[0016] In the above technical solution, the limiting block is further located at the top of the stainless steel flat key.
[0017] In this technical solution, it is ensured that the limiting block can limit the movement of the stainless steel flat key.
[0018] In the above technical solution, the core and the threaded connector are integrally formed, and the internal hexagonal bolt and the limiting block are integrally formed.
[0019] In this technical solution, the structural stability of the sleeve and threaded joint is ensured, as well as the structural stability of the internal hexagonal bolt and the limit block are guaranteed.
[0020] In the above technical solution, one side of the stainless steel flat key is in contact with the inner wall of the sleeve.
[0021] In this technical solution, the inner wall of the sleeve is ensured to limit the movement of the stainless steel flat key.
[0022] In the above technical solution, furthermore, the peripheral side of the stainless steel flat key contacts the inner wall of the limiting groove.
[0023] In this technical solution, it is ensured that the stainless steel flat key will not wobble within the limiting groove.
[0024] The beneficial effects of this utility model are:
[0025] 1. The nozzle uses a telescopic structure. Through the cooperation of the sleeve, core, limiting groove and limiting block, it ensures that the core will not rotate when moving, thereby enhancing the stability of the core during movement.
[0026] 2. This nozzle uses a telescopic structure. Through the interplay of the internal hexagon bolt, outer cylinder, limiting block, limiting groove, threaded groove, and stainless steel flat key, it ensures that personnel can easily replace stainless steel flat keys of different lengths. This allows adjustment of the distance between the top of the stainless steel flat key and the top of the limiting groove, enabling control over the extension length of the sleeve core. This ensures that the tops of multiple sleeve cores are flush after full extension, guaranteeing that it does not affect use and also enhances aesthetics. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1 - Figure 7 This application will be described in further detail.
[0037] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0038] Example 1: This example provides a telescopic structure for a nozzle, including:
[0039] Sleeve 1, sleeve core 2 is slidably installed inside sleeve 1, threaded joint 3 is fixedly installed at the top of sleeve core 2, and threaded groove 10 is opened on the periphery of sleeve 1 and at its upper end, and outer cylinder 4 is threadedly installed on threaded groove 10.
[0040] A limiting groove 5 is formed on the periphery of the core 2. A magnet 6 is fixedly installed in the limiting groove 5. A stainless steel flat key 7 is provided in the limiting groove 5 and on one side of the magnet 6. An internal hex bolt 8 is threaded on the periphery of the outer cylinder 4. One end of the internal hex bolt 8 extends through the periphery of the outer cylinder 4 into the limiting groove 5 and is fixedly installed with a limiting block 9.
[0041] In use, when the sleeve 1 drives the sleeve core 2 to move up and down, the sleeve core 2 will drive the limiting groove 5 to move during the movement, so that the limiting block 9 slides in the limiting groove 5. At the same time, under the limitation of the limiting block 9 and the limiting groove 5, it can be ensured that the sleeve core 2 will not rotate when it moves, thereby enhancing the stability of the sleeve core 2 when it moves.
[0042] When encountering a situation where the water level in a pool is the same but the bottom is uneven, it is necessary to adjust the extension height of different sleeve cores 2. Personnel can use a hex wrench to turn the internal hex bolt 8. Under the action of the thread, the internal hex bolt 8 will rotate and move outward on the outer cylinder 4. At the same time, the internal hex bolt 8 will drive the limit block 9 to rotate and move until the limit block 9 disengages from the limit groove 5. At this point, the limit block 9 can release the restriction on the outer cylinder 4, and personnel can rotate the outer cylinder 4. Under the action of the thread, the outer cylinder 4 can be turned out of the threaded groove 10. Then, the outer cylinder 4 can be moved upward, allowing personnel to remove the stainless steel flat key 7 from the limit groove 5. Then, replace the stainless steel flat key 7 with one of appropriate length and place it into the bottom of the limiting groove 5. At this time, the stainless steel flat key 7 will be attracted to the magnet 6, ensuring that the stainless steel flat key 7 will not fall off without external force. Then, the personnel put the outer cylinder 4 back into the threaded groove 10 and rotate the internal hex bolt 8 again so that the limiting block 9 enters the limiting groove 5 and abuts against the top of the stainless steel flat key 7. This ensures that it is easy for personnel to replace stainless steel flat keys 7 of different lengths, thereby adjusting the distance between the top of the stainless steel flat key 7 and the top of the limiting groove 5, so as to control the length of the sleeve 2 extending out.
[0043] Example 2: This example provides a telescopic structure for a nozzle. In addition to the technical solutions of the above examples, it also has the following technical features: the sleeve core 2 is located inside the outer cylinder 4, and the inner wall of the outer cylinder 4 is in contact with the periphery of the sleeve core 2.
[0044] Among these measures, ensuring the structural stability of the sleeve core 2 and the outer cylinder 4 is crucial.
[0045] Example 3: This example provides a telescopic structure for a nozzle. In addition to the technical solutions of the above examples, it also has the following technical features: the stainless steel flat key 7 is magnetically connected to the magnet 6, and the stainless steel flat key 7 is located at the bottom of the limiting groove 5.
[0046] Among these measures, it is ensured that the stainless steel flat key 7 can be attracted to the magnet 6, that the stainless steel flat key 7 will not easily fall off without the action of external force, and that the structure of the stainless steel flat key 7 is stable.
[0047] Example 4: This example provides a telescopic structure for a nozzle. In addition to the technical solutions of the above examples, it also has the following technical features: the limiting block 9 is movably connected to the limiting groove 5, and the periphery of the limiting block 9 is in contact with the inner wall of the limiting groove 5.
[0048] Specifically, it ensures that the limiting block 9 can rotate and slide normally within the limiting groove 5, and that the limiting block 9 and the limiting groove 5 can limit the sleeve 2, thus ensuring the stability of the sleeve 2 when it moves.
[0049] Example 5: This example provides a telescopic structure for a nozzle. In addition to the technical solutions of the above examples, it also has the following technical features: the limiting block 9 is located on the top of the stainless steel flat key 7.
[0050] Among them, the limit block 9 is designed to limit the movement of the stainless steel flat key 7.
[0051] Example 6: This example provides a telescopic structure for a nozzle. In addition to the technical solutions of the above examples, it also has the following technical features: the core 2 and the threaded connector 3 are integrally formed, and the internal hexagon bolt 8 and the limiting block 9 are integrally formed.
[0052] Among them, ensuring the structural stability of the sleeve core 2 and the threaded joint 3, and ensuring the structural stability of the internal hexagon bolt 8 and the limit block 9.
[0053] Example 7: This example provides a telescopic structure for a nozzle. In addition to the technical solutions of the above examples, it also has the following technical features: one side of the stainless steel flat key 7 is in contact with the inner wall of the sleeve 1.
[0054] In this process, the inner wall of the sleeve 1 is ensured to limit the movement of the stainless steel flat key 7.
[0055] Example 8: This example provides a telescopic structure for a nozzle. In addition to the technical solutions of the above examples, it also has the following technical features: the periphery of the stainless steel flat key 7 is in contact with the inner wall of the limiting groove 5.
[0056] Among these measures, it is ensured that the stainless steel flat key 7 will not wobble within the limiting groove 5.
[0057] It is worth noting that the stainless steel flat key 7 is martensitic stainless steel, which has high strength and hardness and can usually be attracted by magnet 6.
[0058] Working principle: When the sleeve 1 drives the core 2 to move up and down, the core 2 will drive the limiting groove 5 to move during the movement, so that the limiting block 9 slides in the limiting groove 5. At the same time, under the limitation of the limiting block 9 and the limiting groove 5, it can be ensured that the core 2 will not rotate when it moves, thereby enhancing the stability of the core 2 when it moves.
[0059] When encountering a situation where the water level in a pool is the same but the bottom is uneven, it is necessary to adjust the extension height of different sleeve cores 2. Personnel can use a hex wrench to turn the internal hex bolt 8. Under the action of the thread, the internal hex bolt 8 will rotate and move outward on the outer cylinder 4. At the same time, the internal hex bolt 8 will drive the limit block 9 to rotate and move until the limit block 9 disengages from the limit groove 5. At this point, the limit block 9 can release the restriction on the outer cylinder 4, and personnel can rotate the outer cylinder 4. Under the action of the thread, the outer cylinder 4 can be turned out of the threaded groove 10. Then, the outer cylinder 4 can be moved upward, allowing personnel to remove the stainless steel flat key 7 from the limit groove 5. Then, replace the stainless steel flat key 7 with one of appropriate length and place it into the bottom of the limiting groove 5. At this time, the stainless steel flat key 7 will be attracted to the magnet 6, ensuring that the stainless steel flat key 7 will not fall off without external force. Then, the personnel put the outer cylinder 4 back into the threaded groove 10 and rotate the internal hex bolt 8 again so that the limiting block 9 enters the limiting groove 5 and abuts against the top of the stainless steel flat key 7. This ensures that it is easy for personnel to replace stainless steel flat keys 7 of different lengths, thereby adjusting the distance between the top of the stainless steel flat key 7 and the top of the limiting groove 5, so as to control the length of the sleeve 2 extending out.
[0060] When the sleeve core 2 moves upward, it will drive the stainless steel flat key 7 to move through the limiting groove 5 until the top of the stainless steel flat key 7 abuts against the limiting block 9. At this time, the stainless steel flat key 7 can limit the sleeve core 2, ensuring that the personnel can adjust the extension length of the sleeve core 2 at will according to the distance from the bottom of the pool to the water surface. This ensures that after multiple sleeve cores 2 are fully extended, the tops of multiple sleeve cores 2 can be flush, ensuring that it will not affect the use and can also increase the aesthetics.
