DETAILED DESCRIPTION

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] The phototherapy device cannot be flexibly adjusted to be vertical or horizontal, which limits its scope of use and usage scenarios. If the user needs to lie down to use the phototherapy device, but the phototherapy device can only be used vertically, then the user has to change his sleeping or sitting position to use it, which will also increase the user's discomfort. Therefore, the flexibility of the phototherapy device is crucial to improving user experience and expanding usage scenarios.

[0044] Based on the above situation, the present application provides a bracket for installing a phototherapy mechanism and adjusting the direction and angle of the phototherapy mechanism. Figures 1 to 11 , the bracket provided in the embodiment of the present application is now described.

[0045] See also Figure 1 to Figure 2 A bracket provided in an embodiment of the present application includes a base 11, a sliding frame 12, a telescopic arm 13 and a connecting head 16 for supporting a phototherapy mechanism 20, the sliding frame 12 is hinged to the top of the base 11, and the telescopic arm 13 is slidably inserted into the sliding frame 12; the bracket also includes a first locking structure 14 for locking the rotation angle of the sliding frame 12 relative to the base 11 and a second locking structure 15 for locking the sliding position of the telescopic arm 13 and the sliding frame 12, the first locking structure 14 is installed on the base 11, the second locking structure 15 is installed on the sliding frame 12, and the connecting head 16 is installed on the free end of the telescopic arm 13.

[0046] This phototherapy bracket realizes the height adjustment and angle adjustment functions of the bracket through the combined design of the base 11, the sliding frame 12 and the telescopic arm 13, so that the phototherapy mechanism can adapt to the needs of different users. Specifically, the sliding frame 12 is hinged to the top of the base 11, so that the sliding frame 12 can rotate around the base 11 at multiple angles to meet the phototherapy needs of different positions and postures; the telescopic arm 13 is installed in the sliding frame 12 by sliding insertion, and the length of the telescopic arm can be adjusted along the sliding frame 12 as needed, thereby adjusting the distance between the phototherapy mechanism and the part to be treated. The first locking structure 14 is fixed to the base 11, and is mainly used to lock the rotation angle of the sliding frame 12 relative to the base 11. After selecting a suitable irradiation angle, the first locking structure 14 can ensure that the sliding frame 12 remains stationary to prevent angle changes caused by external factors during phototherapy, thereby significantly improving the accuracy of phototherapy operations. The second locking structure 15 is located on the slide frame 12, which is responsible for locking the sliding position of the telescopic arm 13 in the slide frame 12. When the telescopic arm 13 is adjusted to the ideal extension length, it is fixed by the second locking structure 15 to prevent the telescopic arm 13 from sliding due to accidental touching during the treatment process, thereby ensuring that the phototherapy distance is always stable and improving the stability of the treatment effect. Finally, the connector 16 is installed at the end of the telescopic arm 13 to carry and install the phototherapy mechanism to ensure that it can adjust the position and angle together with the telescopic arm 13.

[0047] See also Figures 1 to 5 In one embodiment of the present application, a strip groove 1130 for receiving the telescopic arm 13 is provided on the base 11 , the strip groove 1130 is arranged along the height direction of the base 11 , and the slide frame 12 is located at the top of the strip groove 1130 .

[0048] The designed strip groove 1130 structure allows the telescopic arm 13 to be flexibly stored in the base 11, realizing the optimal use of space, making the entire bracket structure compact and convenient to carry and store, while reducing the space occupied by the bracket to adapt to different usage environments and needs. The strip groove 1130 is arranged along the height direction of the base 11, which ensures the stability and stability of the telescopic arm 13 during the retraction or extension process, avoids shaking or tilting due to improper operation, and improves the positioning accuracy and safety during phototherapy. The sliding frame 12 is located at the top of the strip groove 1130, and cooperates with the telescopic action of the telescopic arm 13 to effectively guide and limit, ensuring that the telescopic arm 13 always remains in the preset track during the sliding process to prevent it from getting off the track, thereby enhancing the overall structural strength and service life of the bracket.

[0049] See also Figure 7 In one embodiment of the present application, the base 11 includes a base frame 111, a vertical frame 112 arranged on the upper side of the base frame 111, and two support arms 113 arranged in parallel on the top of the vertical frame 112. The two support arms 113 are respectively located on opposite sides of the vertical frame 112 along the width direction (the direction shown by the X-axis in the figure), and a strip groove 1130 is formed between the two support arms 113. The end of the support arm 113 away from the base frame 111 is hingedly connected to the sliding frame 12, and the first locking structure 14 is installed on the support arm 113.

[0050] The base 11 is composed of a base frame 111 and a stand frame 112. This layered design enhances the basic support strength of the entire bracket and ensures the stability of the equipment during operation. The position setting of the strip groove 1130 fully reflects the compactness and practicality of the phototherapy bracket design in this application, which not only saves space, but also facilitates the operator to assemble, adjust and use the equipment. The first locking structure 14 is installed on the support arm 113. Its function is to lock the sliding frame 12 after it is adjusted to a suitable position to ensure that the position of the sliding frame 12 and the telescopic arm 13 carried by it will not move during the phototherapy process, thereby ensuring the stability and accuracy of the phototherapy operation. The length of the two support arms 113 is greater than the length of the telescopic arm 13, and the distance between the two support arms 113 is greater than the width of the telescopic arm 13.

[0051] See also Figures 1 to 5 In one embodiment of the present application, the base frame 111 includes a crossbeam 1111 supporting the vertical frame 112 and support beams 1112 arranged in parallel at both ends of the crossbeam 1111; an extension plate 1113 is detachably mounted on one end of the support beam 1112, and the extension plate 1113 is extended in a direction away from the support beam 1112; and / or a roller 17 is installed on one side of the crossbeam 1111.

[0052] The base frame 111 supports the upright frame 112 through the crossbeam 1111, so that the entire phototherapy support has good mechanical balance and load-bearing capacity. An extension plate 1113 is detachably installed at one end of the support beam 1112. This design allows the phototherapy support to be expanded in size according to the actual application scenario or treatment needs. If the connector 16 is connected to a large phototherapy mechanism, the extension plate 1113 is adjusted out to better support the phototherapy mechanism. A roller 17 is installed on one side of the crossbeam 1111, making the support a movable device. The position can be easily adjusted without consuming a lot of manpower, especially in medical institutions or home care places, which improves the mobility and ease of use of the device. The roller 17 is rotatably installed on the side of the crossbeam 1111. When the support needs to be moved, the roller 17 is turned out in the direction of the bottom surface and engaged with the fastener to move the support. Alternatively, the support beam 1112 is configured to be rotatable upward along the cross beam 1111. When the bracket needs to be moved, the support beam 1112 is flipped upward. At this time, the bracket is tilted to allow the roller 17 to contact the ground, thereby pushing the bracket.

[0053] See also Figure 3 In one embodiment of the present application, the connecting head 16 includes an articulated head 161 and a mounting plate 162 , one end of the articulated head 161 is hingedly connected to the telescopic arm 13 , and the mounting plate 162 is rotatably mounted on the other end of the articulated head 161 .

[0054] The mounting plate 162 is used to connect with the phototherapy mechanism. The rotation design of the mounting plate 162 allows the mounting plate 162 to rotate independently. The plane formed by the rotation of the mounting plate 17 is parallel to the radial straight line of the telescopic arm 13, so that the phototherapy mechanism can be easily and accurately positioned and fixed in the optimal irradiation position according to different application scenarios.

[0055] See also Figure 6 and Figure 7 In one embodiment of the present application, a rotating shaft 131 connected to a hinged joint 161 is inserted at the free end of the telescopic arm 13, and curved arms 132 are respectively provided at both ends of the rotating shaft 131. One end of the curved arm 132 away from the rotating shaft 131 is bent to form a handle 1321.

[0056] The free end of the telescopic arm 13 is connected to the hinge joint 161 by inserting the rotating shaft 131, so that the phototherapy mechanism can perform more precise angle adjustment based on the telescopic arm 13. The introduction of the rotating shaft 131 adds another rotation dimension to the phototherapy mechanism, thereby improving the accuracy and flexibility of positioning the irradiation point of the light source. A curved arm 132 is respectively provided at both ends of the rotating shaft 131, and the end of the curved arm 132 away from the rotating shaft is bent to form a handle 1321. This design allows medical staff or users to conveniently adjust the angle and direction of the phototherapy mechanism by directly holding the handle 1321, without directly contacting the more precise rotating shaft 131 part, which not only facilitates operation, but also avoids potential operating errors and damage to the equipment.

[0057] See also Figure 6 In one embodiment of the present application, the radial direction of the rotating shaft 131 is perpendicular to the length direction of the telescopic arm 13, so that the plane formed by the rotation of the hinge head 161 relative to the rotating shaft 131 is parallel to the length direction of the telescopic arm 13, and the plane formed by the rotation of the hinge head 161 relative to the rotating shaft 131 is perpendicular to any plane formed by the rotation of the mounting plate 162 relative to the hinge head 161.

[0058] The plane formed by the rotation of the hinge 161 relative to the shaft 131 is parallel to the length direction of the telescopic arm 13, so that the phototherapy device can be adjusted according to the required angle to meet the treatment needs of different patients. In addition, the plane formed by the rotation of the hinge 161 relative to the shaft 131 is perpendicular to any plane formed by the rotation of the mounting plate 162 relative to the hinge 161, which is not likely to cause the center of gravity of the bracket to be unstable.

[0059] Please also read Figures 6 to 11 In another embodiment of the present application, it includes a first friction disc 141 connected to one side of the slide frame 12, a second friction disc 142 for cooperating with the first friction disc 141 to lock the rotation angle of the slide frame 12, a first screw rod 143 connected to the second friction disc 142 at one end, and a first hand wheel 144 connected to the other end of the first screw rod 143, and the middle part of the first screw rod is connected to the base 11. In another embodiment of the present application, the first locking structure 14 is a quick-release buckle.

[0060] Please also read Figures 6 to 11 In another embodiment of the present application, please refer to Figures 6 to 11 The second locking structure 15 includes an abutment member 151 for abutting the side of the telescopic arm 13, a second screw rod 152 connected to the abutment member 151 at one end, and a second hand wheel 153 connected to the other end of the second screw rod 152, and the middle part of the second screw rod 152 is threadedly matched with the slide frame 12. In another embodiment of the present application, the second locking structure 15 is a quick-release lock buckle.

[0061] Through the cooperation of the first friction disc 141, the second friction disc 142, the first screw 143 and the first hand wheel 144, the rotation angle of the slide frame 12 can be precisely adjusted. By connecting the middle part of the first screw 143 with the base 11, the stability of the first locking structure 14 can be ensured to avoid loosening during use. At the same time, through the cooperation of the abutment 151, the second screw 152 and the second hand wheel 153, the side of the telescopic arm 13 can be supported, thereby achieving precise adjustment of the telescopic length of the telescopic arm 13. At the same time, through the middle part of the second screw 152 and the threaded cooperation of the slide frame 12, the stability of the second locking structure 15 can be ensured. In addition, the setting of the quick-release lock makes the adjustment process more convenient and improves the efficiency of use.

[0062] Optionally, the first friction disk 141 is a toothed disk, and the second friction disk 142 is a toothed disk, or the first friction disk 141 is a rubber gasket, and the second friction disk 142 is a rubber gasket.

[0063] See also Figure 2 In one embodiment of the present application, a battery holder 18 is installed on the base 11, and a power connection port 181 for loading a mobile power source is opened on the battery holder 18; the number of the power connection ports 181 is multiple, and the multiple power connection ports 181 are symmetrically distributed on opposite sides of the base 11 along the width direction.

[0064] The battery holder 18 on the base 11 is equipped with a plurality of power connection ports 181, which can be used to load mobile power sources. This makes the bracket portable, and the user can use the bracket to power the phototherapy mechanism without relying on a fixed power source, and perform treatment more flexibly. Especially in situations where there is no access to a power source, such as outdoor activities or temporary mobile treatment points, the power provided by the mobile power source can ensure the normal operation of the equipment. Because phototherapy mechanisms usually have high power, when large-area treatment is required, mobile power sources in multiple power connection ports 181 can be used to power different parts of the phototherapy mechanism respectively.

[0065] See also Figures 1 to 5 An embodiment of the present application also provides a phototherapy device, including a phototherapy mechanism 20, and also includes a bracket in any of the above embodiments, and the phototherapy mechanism 20 is installed on the connecting head 16.

[0066] By installing the phototherapy mechanism 20 on the connector 16, the bracket can be used to support the phototherapy mechanism 20, and then the user can adjust the angle of the phototherapy mechanism 20 by adjusting the components of the bracket according to the needs. In addition, the bracket can be used to freely flip the phototherapy mechanism 20, and the user does not need to stand to use the phototherapy mechanism 20, but can use it while sitting or lying.

[0067] The above contents are further detailed descriptions of the present invention in combination with specific implementation methods, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
