Description

Technical Field

[0001] This utility model relates to jewelry accessory technology, and more particularly to an ear-piercing device with a hollow tube. Background Technology

[0002] Existing ear piercing devices are described in CN202223295019.2 and CN202420550091.5, etc. These devices have an earring holder fixed at one end and an earring fixed at the other. During use, the earring is driven into the earring holder by external force, simultaneously causing the mounting components between the earring and the earring holder to break. Therefore, even if most parts of the ear piercing device are usable, the core component breaks, rendering the device a disposable item. Each ear piercing device can only be used with a single earring. Furthermore, when the user uses the ear piercing device independently, the earring post is always exposed, making it susceptible to earlobe bacterial infection. Therefore, it is necessary to provide an ear piercing device that does not require a single earring. Utility Model Content

[0003] To address the shortcomings of the existing technology, this invention proposes an ear-piercing device with a hollow tube. The hollow tube replaces the ear stud, is connected to the ear stud socket, and the ear stud is inserted into the hollow tube. This facilitates the use of different ear studs and reduces earlobe infection.

[0004] The technical solution of this utility model is implemented as follows:

[0005] An ear-piercing device with a hollow tube, comprising:

[0006] A pusher having a first chamber and a second chamber;

[0007] A clamping member is located in the first chamber. The clamping member includes a first clamp and a second clamp, and a hollow tube is fixed between the first clamp and the second clamp.

[0008] A piston has a mounting portion for mounting an earring seat and a guide portion that slidably extends into a second chamber. The guide portion has a limiting piece that restricts the clamping member within a first chamber. When the guide portion slides along the second chamber, the mounting portion drives the earring seat to connect to the hollow tube.

[0009] An elastic element is located within the second chamber, and the elastic element pushes the guide portion away from the second chamber;

[0010] The hollow tube is characterized by having a through groove, and when the earring seat is connected to the hollow tube, the diameter of the through groove is larger than the diameter of the earring shaft.

[0011] In this invention, the earring holder has a mounting hole that is coaxial with the center line of the hollow tube. The diameter of the mounting hole is smaller than the outer diameter of the hollow tube, and the center line of the hollow tube is parallel to the sliding direction of the guide portion.

[0012] In this invention, the hollow tube has an acute-angle cut, which is inserted into the earring holder.

[0013] In this invention, the earring includes a needle tip, a rod, and a spherical body, and the diameter of the through groove is larger than the diameter of the spherical body.

[0014] In this utility model, the earring holder has a cylindrical tail, the mounting part has a clearance groove, a placement groove and an elastic piece located behind the placement groove, the cylindrical tail is placed in the placement groove, the elastic piece abuts against the cylindrical tail, when the hollow tube is inserted into the cylindrical tail, the elastic piece disengages from the placement groove and releases the cylindrical tail.

[0015] In this utility model, the tail of the guide portion has an oblique wedge, and the bottom of the second chamber has a guide groove extending along the sliding direction of the guide portion. The oblique wedge extends into the guide groove, and the outer side of the oblique wedge abuts against the inner side of the guide groove.

[0016] In this invention, the guide groove has a blocking wall that limits the maximum stroke of the wedge.

[0017] In this invention, the side of the guide portion has a guide buckle, and the side of the second chamber has a guide groove extending along the sliding direction of the guide portion, with the guide buckle extending out from the guide groove.

[0018] In this invention, the guide portion has a guide rib, and the second chamber has a guide blind groove extending along the sliding direction of the guide portion. The guide rib slides along the guide blind groove to guide the piston relative to the pusher.

[0019] The hollow tube ear-piercing device of this invention has the following advantages: This invention uses a hollow tube instead of an earring, which connects to the earring holder. After installation, the diameter of the through-slot in the hollow tube is larger than the diameter of the earring shaft. The through-slot is used to insert the earring, facilitating the use of different earrings. Simultaneously, the hollow tube prevents the operator from frequently touching the earring shaft when using the ear-piercing device, maintaining earlobe hygiene and preventing infection. Furthermore, when the hollow tube is long, the piston stroke is large.

Detailed Implementation

[0030] To better understand the purpose, technical solution, and advantages of this application, the application is described and illustrated below in conjunction with the accompanying drawings and embodiments. Example

[0031] As shown in Figures 1 to 5, the ear-piercing device with a hollow tube in this embodiment includes: a fixing member 10, a clamping member 20, a piston member 30, and an elastic member 40. The fixing member 10 has a first chamber 11 and a second chamber 12. The clamping member 20 is located within the first chamber 11 and includes a first clamp 21 and a second clamp 22. A hollow tube 50 is fixed between the first clamp 21 and the second clamp 22. The piston member 30 has a mounting portion 31 for mounting an earring seat 60 and a guide portion 32 that slidably extends into the second chamber 12. The guide portion 32 has a limiting piece 33 that restricts the clamping member 20 within the first chamber 11. The limiting piece 33 abuts against the clamping member 20 from below, pressing the clamping member 20 into the first chamber 11. The first chamber 11 holds the first clamp 21 and the second clamp 22 in a mating state, thereby fixing the hollow tube 50. When the guide portion 32 slides along the second chamber 12, the mounting portion 31 drives the earring seat 60 to connect to the hollow tube 50. The elastic element 40 is located inside the second chamber 12, and the elastic element 40 pushes the guide portion 32 away from the second chamber 12. In this embodiment, the elastic element 40 is a spring.

[0032] The earring holder 60 has a mounting hole 61, which is coaxial with the centerline of the hollow tube 50. The diameter of the mounting hole 61 is smaller than the outer diameter of the hollow tube 50, and the centerline of the hollow tube 50 is parallel to the sliding direction of the guide portion 32. The hollow tube 50 has a through groove 51. The hollow tube 50 has an acute-angle cut 52, which is inserted into the earring holder 60. When the earring holder 60 is connected to the hollow tube 50, the hollow tube 50 passes through the mounting hole 61 and is held in place by the earring holder 60. The through groove 51 may deform. The earring 70 includes a tip 71, a shaft 72, and a spherical body 73. The elastic modulus of the hollow tube 50 still ensures that the diameter of the through groove 51 is larger than the diameter of the shaft 72 of the earring. The needle tip 71 can be an elastic sphere or a thread, used to engage with the mounting hole 61 of the earring holder 60. Thus, earrings of different shapes can be inserted into the through-slot 51 of the hollow tube 50. Simultaneously, the hollow tube 50 is pulled out through the acute-angle cut 52, and the earring remains on the earring holder 60. Furthermore, the diameter of the through-slot 51 is smaller than the diameter of the sphere 73, allowing the sphere 73 to control the depth to which the rod 72 is inserted into the hollow tube 50.

[0033] The earring holder 60 has a cylindrical tail 62. The mounting part 31 has a relief groove 34, a placement groove 35, and an elastic piece 36 located behind the placement groove 35. The cylindrical tail 62 is placed in the placement groove 35, and the elastic piece 36 abuts against the cylindrical tail 62. When the hollow tube 50 is inserted into the cylindrical tail 62, the elastic piece 36 disengages from the placement groove 35 and releases the cylindrical tail 62. After the elastic piece 36 behind the placement groove 35 breaks off, it can provide a longer stroke for the hollow tube 50, and the earring holder 60 can be fixed in the middle of the hollow tube 50 to prevent the hollow tube 50 from falling off.

[0034] The working principle of this utility model is as follows: the earring seat 60 is fixed inside the mounting part 31, and the hollow tube 50 is fixed inside the clamping member 20. The hollow tube 50 and the earring seat 60 are aligned with the human ear. When external force is applied to the rear of the piston member 30 and the fixing member 10 respectively, the elastic member 40 is compressed, the guide part 32 slides inward along the second chamber 12, the mounting part 31 moves closer to the clamping member 20, and the earring seat 60 connects to the hollow tube 50. At the same time, the guide part 32 drives the limiting piece 33 to disengage from the clamping member 20. After the clamping member 20 is released by the first chamber 11, the first clamp 21 and the second clamp 22 disengage from each other. After the external force disappears, the spring pushes the guide part 32 away from the second chamber 12, and the mounting part 31 moves away from the clamping member 20. The mounting part 31 releases the earring seat 60, and the clamping part 20 releases the hollow tube 50, removing the ear piercing device. The hollow tube 50 and the earring seat 60 are then fixed to the ear, completing the ear piercing operation. When installing the earring 70, the ball-shaped body 73 is held to insert the rod 72 into the hollow tube 50. Then, the hollow tube 50 is pulled out in the opposite direction. Due to the elasticity of the mounting hole 61 of the earring seat 60, the mounting hole 61 contracts, keeping the rod 72 within the earring seat 60.

[0035] In this embodiment, the tail of the guide portion 32 has a wedge 37a, and the bottom of the second chamber 12 has a guide groove 13a extending along the sliding direction of the guide portion 32. The wedge 37a extends into the guide groove 13a, and the outer side of the wedge 37a abuts against the inner side of the guide groove 13a. The guide groove 13a has a blocking wall 14a, which limits the maximum stroke of the wedge 37a.

[0036] To meet the requirements of different earrings, the length of the hollow tube 50 should be freely adjustable. When the hollow tube 50 is long, the piston 30 has a large stroke. In this invention, the guide part 32 and the guide groove 13a guide the sliding of the earring seat 60, and the guide groove 13a guides the sliding of the wedge 37a, keeping the earring seat 60 always coaxial with the hollow tube 50. Example

[0037] Another preferred embodiment of this ear-piercing device with a hollow tube. Referring to Figures 6 to 9, the rear side of the fixing member 10 has an arc-shaped portion 15b, which is provided with multiple sets of anti-slip strips 16b. The arc-shaped portion 15b corresponds to the shape of the palm, increasing the force-bearing area, making it easier to use and more ergonomic. The first clamp 21 and the second clamp 22, after being paired, form a receiving chamber 23b, in which the spherical body 73 is housed. The receiving chamber may also be provided with an elastic cylinder 24b to enhance the release speed of the spherical body 73. The first clamp 21 has a positioning hole 25b, which is paired and positioned with the corresponding positioning post of the second clamp 22. The ear stud 70 is fixed between the first clamp 21 and the second clamp 22. The guide portion 32 has a first positioning post 81b, the second chamber 12 has a second positioning post 82b, and one end of the elastic member 40 is fitted onto the first positioning post 81b, and the other end is fitted onto the second positioning post 82b.

[0038] In this embodiment, the guide portion 32 has a guide buckle 37b, and the second chamber 12 has a guide groove 13b extending along the sliding direction of the guide portion 32. The guide buckle 37b extends out from the guide groove 13b. Two sets of guide buckles 37b form a double guide buckle, which fixes the guide portion 32 in the second chamber 12, preventing the earring seat 60 on the mounting portion 31 from deviating from the center line of the front hollow tube 50 of the clamping member 20, and ensuring that the earring seat 60 accurately connects to the hollow tube 50 when the piston member 30 drives the earring seat 60 to move. Furthermore, the guide portion 32 has a guide rib, and the second chamber 12 has a guide blind groove extending along the sliding direction of the guide portion 32. The guide rib slides along the guide blind groove to guide the piston member 30 to slide relative to the fixing member 10. The guide rib slides along the guide blind groove to guide the piston member 30 to slide relative to the fixing member 10, which enhances the stability of the piston member 30's sliding.

[0039] The inner wall of the first chamber 11 has a mounting groove 83b, which is located on both sides of the first clamp 21 and the second clamp 22, keeping the contact surfaces (upper and lower sides) of the first clamp 21 and the second clamp 22 in a suspended state. After the limiting piece 33 disengages from the clamping member 20, the first chamber 11 quickly releases the first clamp 21 and / or the second clamp 22. The suspended contact surfaces facilitate the disengagement of the first clamp 21 and the second clamp 22, improving the ease of disengagement of the hollow tube 50.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
