Description

Technical Field

[0001] The utility model relates to the technical field of suction nozzles, in particular to a bakelite suction nozzle needle with an external protection structure. Background Art

[0002] In recent years, the demand in the smart phone market has increased rapidly. The multi-functionalization has increased the number of components of mobile phone products. Therefore, the demand for ultra-small components that can be installed at high density has increased accordingly. When installing ultra-small components, it is often necessary to cooperate with a suction nozzle to achieve the purpose of auxiliary installation. Publication No.: CN204442841U discloses a suction nozzle, including a base, a black head, and a reflector. A cavity is provided at the bottom of the base, and a black head is provided in the cavity. A reflector is connected to the base at the bottom end of the black head. A through hole is provided on the end face of the black head, and the shape of the through hole is special-shaped. Thus, the problem of adsorption of materials with small volume, thin thickness, and light weight by an automatic chip mounter in the electronic industry is solved. It has the characteristics of simple structure, reliable adsorption, and long service life. However, in the process of using the above technology, the device does not have a structure for protecting the black head. When the device is not in use, it is possible that the black head may be accidentally impacted by foreign objects and bent and damaged, thereby affecting the use of the device. Content of the Utility Model

[0003] The purpose of the utility model is to solve the technical problems raised in the above background art.

[0004] The utility model adopts the following technical scheme: A bakelite suction nozzle needle with an external protection structure, including a tube body. A needle tube is fixedly connected inside the tube body. A fixed seat is fixedly connected to the surface of the tube body. A protective shell is slidably connected to the surface of the tube body. One end of the protective shell is fixedly connected inside the fixed seat. Round holes and insertion holes are respectively provided on the surfaces of the fixed seat and the tube body. A sleeve is fixedly connected to the surface of the fixed seat. A circular slider is slidably connected inside the sleeve. A limiting rod is fixedly connected inside the circular slider. The limiting rod is inserted into the round hole and the insertion hole. A first magnet is fixedly connected to the surface of the circular slider.

A handle sleeve 13 is fixedly connected to the surface of the disc handle 12, and the handle sleeve 13 is made of rubber material, which can improve the comfort of holding the disc handle 12 here, and at the same time can also increase the friction when holding the disc handle 12 to avoid slipping. The diameters of the round holes 5 and the jacks 6 are the same and are also the same as the diameter of the limit rod 9, which can make the limit rod 9 fit more closely with the round holes 5 and the jacks 6 and avoid the phenomenon that the protective shell 4 still shakes after being fixed.

[0022] Embodiment 2

[0023] Please refer to Figures 1-3, a support ring block 14 is fixedly connected to the surface of the tube body 1, and a second magnet 15 is fixedly connected to the surface of the support ring block 14. Here, when the protective shell 4 protects the syringe needle 2, the second magnet 15 can be attracted to the inner top surface of the protective shell 4, ensuring that the protective shell 4 does not shake when protecting the syringe needle 2. A chute 16 is provided on the inner wall of the protective shell 4, and a limit block 17 is fixedly connected to the surface of the support ring block 14. The limit block 17 is slidably connected to the inside of the chute 16.

At the same time, it is also convenient for the circular hole 5 to be aligned with the jack 6 when fixing the protective shell 4, facilitating the insertion of the limit rod 9 into it. Then, insert the top end of the protective shell 4 into the inside of the fixed seat 3. Then, push the disc handle 12, and the disc handle 12 drives the pull rod 11 to move into the inside of the sleeve 7 and pushes the limit rod 9 into the circular hole 5 and the jack 6. At this time, the first magnet 10 is attracted to the fixed seat 3, realizing the protection of the syringe needle 2, so that the syringe needle 2 will not be bent and deformed due to accidental impact from foreign objects, affecting the use, and further improving the service life of the syringe needle 2. By setting the sleeve 7, the limit rod 9, the circular ring slider 8, the first magnet 10, the pull rod 11 and the disc handle 12, the fixation of the protective shell 4 is realized, and at the same time, the separation of the protective shell 4 from the fixed seat 3 can be quickly realized.
