Description

Technical Field

[0001] This utility model relates to the field of dental equipment technology, and in particular to a low-speed connector. Background Technology

[0002] Low-speed connectors in dental handpieces are primarily used to connect dental instruments that rotate at low speeds. These connectors are typically designed with a detachable connection, allowing different types to be replaced as needed for treatment. For example, dentists can select different models and functions of low-speed connectors depending on the specific treatment requirements.

[0003] In existing technology, low-speed connectors use spring clips for detachable connection. However, during use, doctors may accidentally press the clip's button, causing the phone to fall off unexpectedly, posing a safety hazard. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a low-speed connector, which aims to solve the problem in the prior art where doctors may accidentally touch the button of the buckle during operation, causing the mobile phone to fall off unexpectedly, posing a safety hazard.

[0005] This utility model provides a low-speed connector, including a plug, a button, a buckle, and a first spring. The plug has an axial groove and a radial through hole. The buckle is movably disposed in the groove. The button extends through the through hole into the groove and is movably connected to the buckle. The button has a limiting ring. One end of the first spring abuts against the plug and the other end is low to the button. When the first spring drives the button to move outward to reset, the limiting ring engages with the buckle. The button has a locking structure for engaging with the buckle so that the button can push the buckle inward to move.

[0006] Furthermore, the snap-fit ​​structure includes a moving rod, a second spring, and a ball bearing. The moving rod passes through the button along its axial direction and has an annular groove along its circumferential direction. One end of the second spring abuts against the button, and the other end abuts against the moving rod. The snap-fit ​​has an arc-shaped groove that matches the ball bearing. The ball bearing is located between the arc-shaped groove and the annular groove. The moving rod is used to drive the ball bearing to snap into the arc-shaped groove.

[0007] Furthermore, the moving rod is provided with a stop ring, the button is provided with a receiving groove, the second spring is located in the receiving groove, one end of the second spring abuts against the bottom wall of the receiving groove, and the other end abuts against the stop ring, the stop ring being engaged in the receiving groove.

[0008] Furthermore, the annular groove includes adjacent arcuate surfaces and snap-fit ​​inclined surfaces. The shape of the arcuate surfaces is adapted to the ball bearings, and the snap-fit ​​inclined surfaces are used to drive the ball bearings to snap into the arcuate groove.

[0009] Furthermore, the ball bearings are provided in a plurality of units.

[0010] Furthermore, the end face of the button is recessed, and the end of the moving rod extends into the recessed surface.

[0011] Furthermore, a first retaining ring protrudes from the inner peripheral wall of the through hole, and a second retaining ring protrudes from the button. One end of the first spring abuts against the first retaining ring, and the other end abuts against the second retaining ring.

[0012] Furthermore, the buckle is provided with an annular groove that is adapted to the limiting ring.

[0013] Furthermore, the latch includes an interconnected snap-fit ​​surface and a guide arc surface, the snap-fit ​​surface extending radially along the connector, and the guide arc surface being inclined relative to the radial direction of the connector.

[0014] Furthermore, the side of the buckle near the connector is adapted to the shape of the inner wall of the clearance groove.

[0015] Beneficial Effects: This utility model provides a low-speed connector, including a plug, a button, a latch, and a first spring. Because the first spring drives the button to move outwards, a limiting ring engages with the latch during reset, preventing the button from detaching from the latch. When the button is accidentally pressed, the latch moves inwards. Since the button and latch can move relative to each other, the latch will not be pushed. When the button needs to move the latch inwards, the latch is engaged by a latching structure on the button, allowing the button to push the latch inwards. Therefore, this invention can prevent the phone from accidentally falling off during use when a doctor might accidentally press the button on the latch. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a low-speed connector, including a plug 1, a button 2, a buckle 3, and a first spring 4. The plug 1 has an axial groove 11 and a radial through hole 12. The buckle 3 is movably disposed in the groove 11. The button 2 extends through the through hole 12 into the groove 11 and is movably connected to the buckle 3. The button 2 has a limiting ring 21. One end of the first spring 4 abuts against the plug 1, and the other end is low to the button 2. When the first spring 4 drives the button 2 to move outward to reset, the limiting ring 21 is engaged with the buckle 3. The button 2 has a locking structure 5, which is engaged with the buckle 3 so that the button 2 can push the buckle 3 inward to move.

[0024] Because the first spring 4 of this application is used to drive the button 2 to move outward, the limiting ring 21 is engaged with the buckle 3 during reset, which can prevent the button 2 from falling off the buckle 3. When the button 2 is accidentally touched, the buckle 3 will move inward. Since the button 2 and the buckle 3 can move relative to each other, the buckle 3 will not be pushed. When the button 2 needs to drive the buckle 3 to move inward, the buckle 3 is engaged by the snap-fit ​​structure 5 on the button 2, thereby allowing the button 2 to push the buckle 3 inward. Therefore, this application can prevent the phone from accidentally falling off when the doctor accidentally touches the button 2 of the buckle 3 during use.

[0025] In one feasible embodiment, the snap-fit ​​structure 5 includes a moving rod 51, a second spring 52, and a ball bearing 53. The moving rod 51 passes through the button 2 along its axial direction and has an annular groove 511 along its circumferential direction. One end of the second spring 52 abuts against the button 2, and the other end abuts against the moving rod. The snap-fit ​​3 has an arc-shaped groove 31 that matches the ball bearing 53. The ball bearing 53 is located between the arc-shaped groove 31 and the annular groove 511. The moving rod 51 drives the ball bearing 53 to snap into the arc-shaped groove 31. Specifically, when it is necessary to detach the mobile phone from the low-speed connector, pressing the moving rod 51 causes it to move inward, pushing the ball bearing 53 against the arc-shaped groove 31. Under the snapping action of the ball bearing 53, the buckle 3, the moving rod 51 and the button 2 are relatively fixed. Therefore, under the pushing action of the moving rod 51, the button 2 drives the buckle 3 to move inward, thereby completing the disassembly of the mobile phone from the low-speed connector.

[0026] In one feasible embodiment, the movable rod 51 is provided with a stop ring 512, the button 2 has a receiving groove 24, and the second spring 52 is located in the receiving groove 24. One end of the second spring 52 abuts against the bottom wall of the receiving groove 24, and the other end abuts against the stop ring 512. The stop ring 512 is engaged in the receiving groove 24. In this embodiment, the stop ring 512 can prevent the movable rod 51 from coming out, and the second spring 52 provides a preload force for the movable rod 51, preventing the movable rod 51 from moving arbitrarily during use and affecting the doctor's operation.

[0027] Specifically, the annular groove 511 includes adjacent arc-shaped surfaces 5111 and snap-fit ​​inclined surfaces 5112. The shape of the arc-shaped surfaces 5111 is adapted to the ball 53, and the snap-fit ​​inclined surfaces 5112 are used to drive the ball 53 to snap into the arc-shaped groove 31.

[0028] In one feasible implementation, a plurality of ball bearings 53 are provided. A plurality of ball bearings 53 can make the buckle 3 bear force evenly, thereby improving the smoothness of the buckle 3 movement.

[0029] In one feasible embodiment, the end face of the button 2 is recessed with a concave surface 22, and the end of the moving rod 51 extends into the concave surface 22. This embodiment can effectively prevent the button 2 from protruding too much, effectively reducing the probability of accidental activation.

[0030] In one feasible implementation, a first retaining ring 13 protrudes from the inner peripheral wall of the through hole 12, and a second retaining ring 23 protrudes from the button 2. One end of the first spring 4 abuts against the first retaining ring 13, and the other end abuts against the second retaining ring 23.

[0031] In one feasible embodiment, the buckle 3 is provided with an annular groove 32 that matches the limiting ring 21. This embodiment allows the limiting ring 21 to be accommodated within the annular groove 32, preventing the limiting ring 21 from protruding.

[0032] In one feasible embodiment, the latch 3 includes an interlocking engagement surface 33 and a guide arc surface 34. The engagement surface 33 extends radially along the connector 1, and the guide arc surface 34 is inclined relative to the radial direction of the connector 1. When it is necessary to connect the mobile phone to the low-speed connector, the guide arc surface can act as a guide, eliminating the need for manual pressing of button 2 and allowing for quick installation. Under the elastic force of the first spring 4, the latch 3 can stably latch the mobile phone and the low-speed connector together; when the mobile phone is removed from the low-speed connector, pressing button 2 can quickly remove the mobile phone, achieving efficient assembly and disassembly.

[0033] In one feasible embodiment, the side of the latch 3 near the connector 1 is adapted to the shape of the inner wall of the clearance groove 11. This embodiment makes the latch 3 fit the clearance groove more closely, improving the tightness of the structure.
