Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a light shield and a dental light curing machine. Background Technology

[0002] The light emitted by the light source of a dental light-curing machine contains certain wavelengths that can damage the optic nerve cells of the human eye. To protect the eyes of medical staff, a light shield needs to be installed on the dental light-curing machine before the light source is turned on. The light shield can block and filter harmful light. Currently, the main structures of light shields are open-ended and closed-ended. The closed-ended type requires being inserted from the front of the lamp head and pushed backward until it is locked in place. After use, it is moved forward through the lamp head and removed. This operation is relatively cumbersome and easily contaminated with bacteria or dirt from the lamp head. The open-ended type can be inserted directly into the lamp head body without going through the front of the lamp head, making the operation simpler and more direct, and easier to keep clean and hygienic. Although the current open-ended type does not need to be inserted through the lamp head, it still needs to be moved backward to lock in place and there is a small displacement within the lamp head body. It requires two steps to fix and is cumbersome to install. Utility Model Content

[0003] The technical problem to be solved by this utility model is that although the current open type does not require the lamp head to be inserted, it still needs to be moved backward to be clamped and kept stable.

Detailed Implementation

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0031] Please refer to Figures 1 to 6 As shown, this application provides a light-shielding plate, which adopts the following technical solution:

[0032] A light-shielding plate includes: a light-shielding body 1 and a connector 100. The connector 100 has an installation groove 25 suitable for assembly with a body 200. The connector 100 is connected to the light-shielding body 1. The inner wall of the installation groove 25 has a plurality of protrusions arranged circumferentially. A groove 21 is provided between any two adjacent protrusions. The connector 100 is elastic.

[0033] The connector 100 described in this application is elastic, allowing the protrusion to deform and connect tightly with the body 200 when assembled with it. This enables the connector 100 to be fixedly connected to the body 200 in one step. Simultaneously, the protrusion provides support, eliminating the need for backward movement to maintain stability after insertion. This simplifies the process, makes operation easier, and improves efficiency. Because the light shield can be snapped onto the lamp head body 200 in one go without needing to move it back and forth, it avoids scratching dirt or water stains, making the light shield cleaner and more hygienic.

[0034] Furthermore, the connector 100 is made of a flexible material, such as silicone, which makes the connector 100 elastic, which facilitates the deformation of the connector 100 and its tight connection with the body 200.

[0035] As attached Figure 1 To be continued Figure 5 As shown, the connector 100 further includes at least two connecting blocks 3, each of which is provided with a protrusion and a groove 21. Multiple connecting blocks 3 are arranged sequentially along the thickness direction of the light-shielding body 1, and a clearance groove 4 is provided between two connecting blocks 3. The connecting blocks 3 are arranged along the axial direction of the body 200, so at least two connecting blocks 3 can provide at least two fixing positions along the axial direction of the body 200. After being engaged, the body 200 does not need to move backward to secure it, allowing the body 200 to adapt to gradually changing diameters and different diameters, simplifying the steps, making operation simpler, and improving efficiency.

[0036] As attached Figure 1 To be continued Figure 5 As shown, further, the multiple protrusions are configured as several first protrusions 22, several second protrusions 23, and several third protrusions 24. Each of the first protrusions 22, second protrusions 23, and third protrusions 24 is sequentially arranged and encloses a mounting groove 25. The second protrusion 23 is disposed between the first protrusions 22 and the third protrusions 24. The first protrusions 22, second protrusions 23, and third protrusions 24 can deform respectively and are tightly connected to different positions of the body 200, providing multiple fixing points in the circumferential direction of the body 200. At the same time, at least two connecting blocks 3 can multiply the fixing points of the protrusions, further improving the fixing ability of the protrusions. In addition, the protrusions also have a certain degree of support, so that after being inserted, the body 200 does not need to move backward to lock and remain stable. At the same time, it can also adapt to the gradually changing diameter and different diameter body sizes, simplifying the steps, making the operation simpler, and improving efficiency.

[0037] As attached Figure 1 To be continued Figure 5 As shown, further, the multiple protrusions are configured as two first protrusions 22, two second protrusions 23, and one third protrusion 24. An inlet 26 is formed between the two first protrusions 22, suitable for the body 200 to be inserted into the mounting groove 25. The first protrusions 22 are inclined towards the second protrusions 23 along the inlet 26. The inclined first protrusions 22 not only guide the body 200 to be inserted, but also deform to close the opening 12 after the body 200 is inserted, increasing the difficulty of the body 200 being removed and further improving the fixing ability of the protrusions.

[0038] As attached Figure 1 To be continued Figure 5 As shown, the two second protrusions 23 are further arranged opposite to each other. The oppositely arranged second protrusions 23 can provide fixing positions on both sides of the body 200. The symmetrical fixing positions can better distribute stress when subjected to force, thereby further improving the fixing ability of the protrusions.

[0039] As attached Figure 1 To be continued Figure 5 As shown, the third protrusion 24 is further positioned towards the inlet 26, with the two first protrusions 22 and / or the two second protrusions 23 located on either side of the third protrusion 24. The third protrusion 24 can connect and fix the body 200 away from the opening 12. Furthermore, the third protrusion 24 is larger than the other protrusions, providing a wider range of connection for the body 200, preventing loosening, and further improving the protrusion's fixing ability.

[0040] As attached Figure 1 To be continued Figure 5 As shown, furthermore, the hardness of the connector 100 is less than the hardness of the light-shielding body 1; and / or,

[0041] The connector 100 has a Shore A hardness of 60-75.

[0042] The hardness of the connector 100 is less than that of the light-shielding body 1, which allows the connector 100 to deform and be connected and fixed to the body 200 in one step. The connector 100, with a Shore A hardness of 60-75, has good elasticity and flexibility, allowing the protrusion to bend to a certain angle without easily breaking. Good elasticity allows the protrusion to deform and connect tightly to the body 200 when assembled. At the same time, the connector 100 is selected with a suitable Shore A hardness, which allows it to deform significantly while providing a certain degree of support. This eliminates the need for the body 200 to move backward to secure it after insertion, simplifying the steps, making the operation simpler, and improving efficiency.

[0043] As attached Figure 1 To be continued Figure 5As shown, further, the light-shielding body 1 and the connector 100 are connected by adhesive. A connecting groove is provided circumferentially along the outer edge of the connector 100. The light-shielding body 1 is embedded in the connecting groove, and the adhesive surfaces are located on the two inner walls of the connecting groove. This allows the light-shielding body 1 and the connector 100 to be manufactured using different materials and processes. After manufacturing, they are connected by adhesive. After embedding and installation, the connector 100 can be easily lifted, and adhesive can be applied to the two inner walls of the connecting groove. This facilitates adhesive application, simplifies the structure, and makes connection convenient. It also prevents the connector 100 from detaching and improves its stability.

[0044] As attached Figure 1 To be continued Figure 5 As shown, the light-shielding body 1 further includes a mounting cavity 11 for mounting the connector 100. The mounting cavity 11 has an opening 12 located at the edge of the light-shielding body 1. The body 200 is adapted to be inserted into the connector 100 through the opening 12 in a direction perpendicular to its axis. The use of an open-type light-shielding plate eliminates the need for the light-shielding plate to be fitted onto the lamp head at the front end of the body 200. The body 200 can be directly inserted into the connector 100 through the opening 12 in a direction perpendicular to its axis, preventing contamination from bacteria or dirt on the lamp head of the body 200.

[0045] As attached Figure 1 To be continued Figure 5 As shown, further, the light-shielding body 1 and the connector 100 are connected by a snap-fit ​​mechanism. The snap-fit ​​mechanism includes a first locking position 5 and a second locking position 6. The light-shielding body 1 is provided with a step 13 that abuts against the first locking position 5 and a slot 14 for the second locking position 6 to be inserted. The first locking position 5 is located near the opening 12, and the second locking position 6 is located on the side of the first locking position 5 away from the opening 12. The outer edge of the connector 100 is provided with a connecting groove along its circumference. The light-shielding body 1 is embedded in the connecting groove, and the snap-fit ​​surfaces of the light-shielding body 1 and the connector 100 are located on the two inner walls of the connecting groove. The first locking position 5 abuts against the step 13, which can effectively prevent the connector 100 from shifting its position towards the opening 12 after it is fixed. At the same time, the insertion and cooperation of the second locking position 6 with the slot 14 further prevents the connector 100 from shifting its position. The structure is simple, the snap-fit ​​is firm, the connection is convenient, the assembly convenience is improved, and the reliability of the connection is enhanced.

[0046] A dental light curing machine includes a body 200 and the light shield.

[0047] The connector 100 described in this application is elastic, allowing the protrusion to deform and tightly connect with the body 200 during assembly. This enables the connector 100 to be fixedly connected to the body 200 in one step. Simultaneously, the protrusion provides support, eliminating the need for backward movement to maintain stability after insertion. This simplifies the process, makes operation easier, and improves efficiency. Because the light shield can be snapped onto the lamp head body in one go without moving it back and forth, it avoids scratching dirt or water stains, making it cleaner and more hygienic. After installation, the light shield blocks light, preventing strong light from harming the eyes.
