Description

Technical Field

[0001] This utility model belongs to the technical field of nozzle connectors, and in particular relates to a nozzle connector. Background Technology

[0002] In various devices and scenarios involving the absorption or transport of gases or liquids, suction nozzles are widely used as key components. For example, in the liquid collection devices of medical diagnostic equipment, a suction nozzle adapter with a liquid collection pump works with a disposable suction nozzle to collect samples and reagents; in electronic product assembly, suction nozzles are used to create a vacuum to pick up parts such as screws. Suction nozzle connectors are used to stably install suction nozzles in corresponding parts of equipment, such as robotic arms or robot end effectors, allowing for precise positioning and operation of the suction nozzles under their control.

[0003] Currently, common nozzle connectors have many shortcomings in practical applications. On the one hand, their versatility is poor when facing the connection requirements of nozzles of different specifications and shapes with equipment. For example, in electronic component placement, existing connectors are difficult to adapt to nozzles for small, irregularly shaped components, often requiring the replacement of the entire equipment, which is time-consuming, labor-intensive, and costly. On the other hand, the connection stability of existing connectors is not ideal. During equipment operation, due to factors such as vibration and airflow impact, the nozzle is prone to loosening or even falling off the connector. For example, if the nozzle connector is loose when a vacuum cleaner is working, it will greatly reduce the vacuuming efficiency and affect the user experience. In view of the above problems, the development of a new type of nozzle connector is urgent. Therefore, we propose a nozzle connector. Utility Model Content

[0004] The purpose of this invention is to provide a nozzle connector to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a suction nozzle connector, including an external air supply hose and a suction nozzle, and further comprising: A connecting seat is provided, with a connecting pipe fixedly installed on its top.

[0021] Example 1: Please see Figure 1 - Figure 5 As shown, this embodiment provides a suction nozzle connector, including an external air supply hose and a suction nozzle, and further includes: A connecting seat 1 is provided, and a connecting pipe 2 is fixedly installed on the top of the connecting seat 1. The connecting seat 1 is used to connect with an external air supply hose, and the connecting pipe 2 is used to connect with a suction nozzle. The connecting pipe 2 has a hollow tubular structure. An air inlet groove 3 is provided on the lower surface of the connecting seat 1. An air vent 4 is provided on the inner top surface of the air inlet groove 3 and is connected to the connecting pipe 2. An annular groove 8 is provided on the outer wall of the connecting pipe 2 at the lower position. A support plate 9 is snapped on the connecting pipe 2 at the position of the annular groove 8. A support sleeve 10 is provided on the top of the support plate 9 and is slidably engaged with the connecting pipe 2. A connecting ring 11 is provided on the top of the support sleeve 10 and is sleeved with the connecting pipe 2. A spring 12 is fixedly installed between the lower surface of the connecting ring 11 and the upper surface of the support sleeve 10. A clamping assembly is provided on the connecting seat 1 and is used to clamp the gas delivery hose; A limiting component is provided on the connecting pipe 2 and the connecting ring 11, and is used to constrain and limit the movement of the connecting ring 11.

[0022] The end of the connecting seat 1 away from the connecting pipe 2 is connected to the air pump's air delivery hose. During connection, the air outlet end of the hose is inserted into the air inlet groove 3, and then clamped by the clamping assembly to achieve fixation. The end of the connecting pipe 2 away from the connecting seat 1 is used to insert the suction nozzle. During installation, the connecting ring 11 is pressed down, and the connecting ring 11 compresses the spring 12. At this time, the limiting assembly loses its constraint. Then, the suction nozzle is inserted into the top opening of the connecting pipe 2, and then the connecting ring 11 is released. Under the elastic action of the spring 12, the connecting ring 11 rebounds and re-engages with the limiting assembly, thereby achieving the snap-fit ​​fixation of the suction nozzle. When air is delivered, the gas flows through the vent 4, through the air inlet groove 3 and the inner cavity of the connecting pipe 2, and is delivered to the suction nozzle to provide power for the suction nozzle.

[0023] This device has a simple structure and is extremely convenient to operate when connecting the nozzle. It overcomes the shortcomings of traditional nozzle connectors, which are inconvenient to operate and have complicated steps when connecting the nozzle, and greatly improves the efficiency of installing and replacing the nozzle.

[0024] Example 2: This embodiment provides a suction nozzle connector, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a clamping component: A rectangular groove 5 is formed on the side wall of the connecting seat 1 and is connected to the air intake groove 3. Threaded holes are symmetrically formed on the side wall of the rectangular groove 5 on both sides of the air intake groove 3. A clamping block 6 is inserted into the rectangular groove 5. The clamping block 6 has an installation groove that matches the threaded hole on the rectangular groove 5. A bolt 7 is inserted into the installation groove on the clamping block 6. The bolt 7 is threadedly engaged with the threaded hole. The clamping block 6 is fixed to the connecting seat 1 by two bolts 7.

[0025] In the normal state, the clamping block 6 is loosely installed in the rectangular groove 5 by two bolts 7. At this time, the external air supply hose can be sent into the interior of the air inlet groove 3 from the bottom opening of the air inlet groove 3. When sending it in, the external air supply hose needs to be pushed to the top of the inner cavity of the air inlet groove 3. Then, the two bolts 7 are turned with a screwdriver. Under the action of the two bolts 7, the clamping block 6 moves closer to the connecting seat 1. As the distance decreases, the clamping block 6 clamps the external air supply hose, thereby fixing the hose on the connecting seat 1.

[0026] By setting up a clamping assembly, the clamping force of the clamping block 6 on the hose is used to clamp and fix the external gas transmission hose.

[0027] Example 3: This embodiment provides a nozzle connector, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the clamping block 6 has a semi-circular structure, and a clamping groove is provided in the middle of the inner sidewall of the clamping block 6. The inner diameter of the clamping groove is smaller than the inner diameter of the air inlet groove 3.

[0028] The inner wall of the clamping groove fits against the outer wall of the external gas delivery hose. When the clamping block 6 is fastened to the connecting seat 1, the external gas delivery hose can be clamped and fixed by the clamping force between the clamping block 6 and the connecting seat 1. It is worth noting that a connector is provided at the connection position between the external gas delivery hose and the connecting seat 1. The connector can be supported by a tubular rigid material, such as a stainless steel sleeve. During installation, the connector and the gas delivery hose are interference-fitted, and then one end of the connector is inserted into the air inlet groove 3. Since the connector is not as flexible as the hose material, it will not deform under the clamping of the clamping block 6. At this time, the clamping assembly can firmly fix the gas delivery hose.

[0029] Example 4: This embodiment provides a nozzle connector, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a limiting component: Multiple embedding holes 14 are distributed circumferentially at equal intervals and are located at the upper part of the connecting pipe 2. Steel balls 15 are movably fitted inside the embedding holes 14. A compression ring 13 is fixedly installed on the lower surface of the connecting ring 11. The compression ring 13 has a bucket-shaped structure with openings on both the upper and lower surfaces and slides with the connecting pipe 2.

[0030] The steel ball 15 is embedded in the embedding hole 14 and can rotate and move slightly, but it will not fall out of the inner cavity of the embedding hole 14. When the limiting component is working, the connecting ring 11 is at the highest position and the inner wall of the extrusion ring 13 is in contact with the steel ball 15, and the multiple steel balls 15 are extruded inward. The part of the steel ball 15 that passes through the embedding hole 14 and is located in the inner cavity of the connecting tube 2 clamps and limits the nozzle, thereby preventing the nozzle from falling off the connecting tube 2. When the nozzle needs to be removed, the operator presses down on the connecting ring 11. At this time, the compression ring 13 moves downward with the connecting ring 11, and the compression ring 13 no longer compresses the steel ball 15. After the steel ball 15 loses external pressure, the operator pulls the nozzle upward. When the nozzle passes the steel ball 15, it will squeeze the steel ball 15 to the outer position. After the steel ball 15 loses external pressure, it can no longer effectively block the nozzle. It is worth noting that when the connecting ring 11 and the spring 12 are not compressed by external force, the upward support force provided by the elasticity of the spring 12 itself is sufficient to ensure that the nozzle will not be displaced due to weak reverse forces such as vibration and airflow impact during operation. That is, the spring 12 provides sufficient compression force for the compression ring 13 to ensure that the steel ball 15 compresses the nozzle.

[0031] By setting a limiting component, the squeezing ring 13 controls the entry and exit of the steel ball 15, and the steel ball 15 limits the suction nozzle, thereby fixing the suction nozzle.

[0032] Example 5: This embodiment provides a nozzle connector, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the lower opening of the compression ring 13 is in contact with the outer wall of the connecting tube 2, and the distance between the upper opening of the compression ring 13 and the circumferential outer wall of the connecting tube 2 is 1-3mm.

[0033] When the extrusion ring 13 moves upward, multiple steel balls 15 can pass through the upper part of the extrusion ring 13. When the extrusion ring 13 is stopped, the steel balls 15 are stuck in the lower middle part of the extrusion ring 13.

[0034] Example 6: This embodiment provides a nozzle connector, which, in addition to the technical solutions of the above embodiments, also has the following technical features: a positioning groove 16 is provided at the edge of the upper surface of the connecting tube 2.

[0035] The positioning groove 16 matches the positioning post on the suction nozzle. When the suction nozzle is inserted downwards, the positioning post on the suction nozzle falls exactly into the positioning groove 16.

[0036] By setting the positioning groove 16, the nozzle is limited and oriented, preventing the nozzle from rotating due to airflow impact inside the connecting tube 2.

[0037] Example 7: This embodiment provides a nozzle connector, which, in addition to the technical solutions of the above embodiments, also has the following technical features: a positioning ring 17 is fixedly installed on the upper surface of the connecting ring 11.

[0038] The positioning ring 17, as a protrusion on the upper surface of the connecting ring 11, matches the recess on the lower surface of the nozzle, so that the nozzle fits perfectly with the connecting ring 11 when it is inserted.

[0039] By setting the positioning ring 17, the possibility of the nozzle shaking is reduced, further improving the stability of the device when fixing the nozzle.

[0040] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
