[0034] Please refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4 The utility model embodiment provides a structure 100 for reducing the shaking of operating lamp, and the packaging device includes a first connecting piece 1, at least one elastic piece 2, at least one buffer piece 3 and a second connecting piece 4;At least one annular groove 11 is formed in the outer periphery of the first connecting piece 1;At least one elastic piece 2 is sleeved in at least one annular groove 11;At least one buffer piece 3 is sleeved on the outer periphery of at least one elastic piece 2;The second connecting piece 4 is provided with a containing cavity 41, the first connecting piece 1 is inserted into the containing cavity 41, at least one elastic piece 2 and at least one buffer piece 3 are located in the containing cavity 41, and the outer periphery of at least one buffer piece 3 abuts against the inner wall of the containing cavity 41. Thus, on the one hand, the gap between the first connecting piece 1 and the second connecting piece 4 can be filled, and on the other hand, the friction between the first connecting piece 1 and the second connecting piece 4 can be increased, so that the structure 100 for reducing the shaking of operating lamp can be prevented from shaking during use.
[0035] In the embodiments of the present application, the at least one elastic member 2 is sleeved in the at least one annular groove 11, which means that the first connecting member 1 can be provided with a plurality of annular grooves 11, and each annular groove 11 can be sleeved with an elastic member 2. The at least one buffer member 3 is sleeved on the outer periphery of the at least one elastic member 2, which means that the outer periphery of each elastic member 2 can be sleeved with a buffer member 3. The first connecting member 1 can be provided with a plurality of annular grooves 11, each of which can be sleeved with an elastic member 2, and the outer periphery of each elastic member 2 can be sleeved with a buffer member 3. Alternatively, some annular grooves 11 can be sleeved with elastic members 2 and buffer members 3, and some annular grooves 11 can not be sleeved with elastic members 2 and buffer members 3. Alternatively, some annular grooves 11 can be sleeved with elastic members 2 and buffer members 3, and some annular grooves 11 can be sleeved with buffer members 3.
[0036] In the embodiments of the present application, the structure 100 for reducing the shaking of the surgical lamp can be a surgical lamp, a medical related lighting device, any other lighting device, or any other non-lighting device formed by the connection and combination of two or two parts. When the structure 100 for reducing the shaking of the surgical lamp is a surgical lamp, the existence of the elastic member 2 and the buffer member 3 eliminates the gap between the first connecting member 1 and the second connecting member 4 of the surgical lamp, thereby avoiding the shaking of the surgical lamp during the operation of the doctor.
[0037] In the embodiments of the present application, the first connecting member 1 can be a bend pipe joint on the surgical lamp, and the second connecting member 4 can be a spring arm joint on the surgical lamp. When the bend pipe joint is connected with the spring arm joint, the elasticity of the wire spring is utilized. After installation, the elasticity of the spring itself can push the buffer member 3 outward, so that the buffer member 3 can be in full contact with the inside of the spring arm joint, or the gap between the two components can be reduced or even eliminated, thereby reducing the shaking between the first connecting member 1 and the second connecting member 4, i.e., reducing the shaking of the surgical lamp during use.
[0038] In some embodiments, referring to Figure 4 and Figure 5 , the elastic member 2 can be formed by multiple bending to form an elastic ring, which can maintain elasticity at any time, support the buffer member 3 sleeved on the outer periphery thereof, so that the buffer member 3 is in abutment with the inner wall of the accommodating cavity 41, thereby eliminating the gap between the first connecting member 1 and the second connecting member 4, increasing the friction between the outer periphery of the buffer member 3 and the inner wall of the accommodating cavity 41, and further preventing the shaking of the first connecting member 1 relative to the second connecting member 4.
[0039] In some embodiments, referring to Figure 5 and Figure 6, the elastic ring (i.e. the elastic member 2) can be bent from a metal wire; the two ends of the elastic ring are oppositely and spacedly arranged. The elastic ring is bent from a metal wire, i.e. there is no joint on the elastic ring, so that the elastic ring is not easily damaged or broken by external force during use; the first end 21 and the second end 22 of the elastic ring are oppositely arranged after being bent, and the first end 21 and the second end 22 are spacedly arranged, i.e. there is a first interval 23. Because of the existence of the first interval 23, the elastic member 2 (i.e. the elastic ring) has a corresponding elastic range, so that on the one hand the elastic member 2 can be set on the outer periphery of the annular groove 11 of the first connecting member 1 at a certain angle, and on the other hand the elastic member 2 can always support the buffer member 3 by its own elastic force, so that the buffer member 3 is kept in abutment with the inner wall of the accommodating cavity 41. In the embodiment of the application, the elastic member 2 can be a wire spring bent from a metal.
[0040] In other embodiments, the elastic member 2 can also be an elastic ring bent from an object made of other materials.
[0041] In some embodiments, referring to Figure 5 and Figure 6 , the elastic ring (i.e. the elastic member 2) includes at least two bent portions 24; wherein the two adjacent bent portions 24 are oppositely and spacedly arranged. The bent portions 24 of the elastic member 2 can be distributed in pairs, and each pair of bent portions 24 has a second interval 25. Because of the existence of the second interval 25, the elastic range of the elastic member 2 (i.e. the elastic ring) can be further increased, so that on the one hand the elastic member 2 can be better set on the outer periphery of the annular groove 11 of the first connecting member 1 at a certain angle, and on the other hand the elastic member 2 can better support the buffer member 3 by its own elastic force, so that the buffer member 3 is kept in abutment with the inner wall of the accommodating cavity 41.
[0042] In the embodiment of the application, the elastic ring includes at least two bent portions 24, i.e. the elastic ring includes at least one pair of bent portions 24, and the elastic ring can also include two pairs or more than two pairs of bent portions 24, and an interval is arranged between each pair of bent portions 24, so as to ensure that the elastic ring has a certain elastic range. The number of pairs of bent portions 24 formed on the elastic ring can be determined according to the width of the annular groove 11 on the first connecting member 1; when the width of the annular groove 11 is relatively narrow, only one pair of bent portions 24 can be arranged; when the width of the annular groove 11 is relatively wide, more bent portions 24 can be arranged, so that the elastic ring can better adapt to the annular groove 11, thereby better supporting the buffer member 3, reducing the gap between the first connecting member 1 and the second connecting member 4, and ensuring the friction between the buffer member 3 and the inner wall of the accommodating cavity 41.
[0043] In some embodiments, referring to Figure 5 and Figure 6The elastic ring can include two bending portions 24; the elastic ring can include a first ring 26 and a second ring 27, and the first ring 26 and the second ring 27 can be connected through the two bending portions 24; and the first ring 26 can be formed by bending the first and second ends of the metal wire. There is a certain distance between the first ring 26 and the second ring 27, so that the elastic member 2 can not only support the buffer member 3 in the radial direction, but also has a certain space for the buffer member 3 in the axial direction, thereby ensuring the abutment between the outer periphery of the buffer member 3 and the inner wall of the accommodating cavity 41, and further enhancing the friction between the outer periphery of the buffer member 3 and the inner wall of the accommodating cavity 41, thereby preventing the first connecting member 1 from shaking relative to the second connecting member 4.
[0044] In some embodiments, referring to Figure 5 , Figure 6 and Figure 7 , the elastic member 2 can abut the inner wall of the buffer member 3 in a first direction; the inner wall of the buffer member 3 can be provided with a protrusion 31; and at least a part of the protrusion 31 is located in the elastic member 2. The first direction is the radial direction of the buffer member 3 and the elastic member 2. The inner wall of the buffer member 3 is provided with the protrusion 31, and the protrusion 31 can be entirely located in the elastic member 2. For example, the protrusion 31 can be inserted between the first ring 26 and the second ring 27, so that the connection between the elastic member 2 and the buffer member 3 is more secure, and the elastic member 2 can better support the buffer. In the embodiments of the present application, the buffer member 3 can be a buffer ring supported by a compression-resistant and wear-resistant material. For example, the buffer member 3 can be a buffer ring supported by a polyoxymethylene material.
[0045] In the embodiments of the present application, the buffer member 3 can be a buffer ring provided with an opening 32, and the buffer ring can be sleeved on the outer periphery of the elastic member 2 through the opening 32. Because of the existence of the opening 32, the buffer ring can also adapt to the expansion and contraction of the elastic member 2 within the elastic range thereof.
[0046] In some embodiments, referring to Figure 5 , Figure 6 and Figure 7 , the elastic member 2 can be bent to form a ring-shaped band, the protrusion 31 can be a ring-shaped protrusion 31, and at least a part of the ring-shaped protrusion 31 is located in the ring-shaped band; and the elastic member 2 abuts the ring-shaped protrusion 31 in a second direction. For example, the ring-shaped protrusion 31 can be entirely located in the ring-shaped band formed by bending the elastic member 2, and on one hand, the ring-shaped band abuts the inner wall of the buffer member 3 in the first direction, and on the other hand, the ring-shaped band can clamp the ring-shaped protrusion 31 of the buffer member 3 in the second direction. The first direction is the radial direction of the elastic member 2 and the buffer member 3, the second direction is the parallel direction of the axial direction of the buffer member 3 and the elastic member 2, and the first direction is perpendicular to the second direction.
[0047] In the embodiments of the present application, referring to Figure 6 andFigure 7 The elastic member 2 is bent to form a ring-shaped band, i.e., a connected ring structure. For example, the ring-shaped band can be two connected rings, the two rings are connected by a pair of bending portions 24, the two rings have a space therebetween, and the pair of bending portions 24 also have a space therebetween. Thus, the ring-shaped band can exert elastic force on the ring-shaped protrusion 31 in the second direction by the two rings, and the two rings connected by the pair of bending portions 24 can clamp the ring-shaped protrusion 31. In addition, the ring-shaped band can exert elastic force on the buffer member 3 in the first direction to support the abutment between the buffer member 3 and the inner wall of the accommodating cavity 41.
[0048] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the first connecting member 1 is configured to rotate relative to the second connecting member 4. For example, the structure 100 for reducing the shaking of the surgical lamp can be a surgical lamp. When the surgical lamp is used, it is often necessary to rotate the surgical lamp to achieve illumination at different positions. When the first connecting member rotates relative to the second connecting member 4, the support of the buffer member 3 by the elastic force of the elastic member 2 is always maintained, and the outer periphery of the buffer member 3 always abuts against the inner wall of the accommodating cavity 41. When the first connecting member rotates relative to the second connecting member 4 by a certain angle and stops, there is no gap between the outer periphery of the buffer member 3 and the inner wall of the accommodating cavity 41, and there is no shaking between the first connecting member 1 and the second connecting member 4.
[0049] In some embodiments, referring to Figure 1 , Figure 4 , Figure 8 and Figure 9In order to better realize the rotation of the first connecting piece 1 relative to the second connecting piece 4, the outer periphery of the first connecting piece 1 can be provided with at least one protruding part 12, and the inner wall of the accommodating cavity 41 can be provided with at least one recessed part 42 corresponding to the position of the at least one protruding part 12; when the first connecting piece 1 is inserted into the accommodating cavity 41 of the second connecting piece 4, the protruding part 12 is located in the recessed part 42. When the first connecting piece 1 is inserted into the accommodating cavity 41 of the second connecting piece 4, the protruding part 12 on the first connecting piece 1 can slide into the recessed part 42 on the inner wall of the accommodating cavity 41, thereby ensuring the connection between the first connecting piece 1 and the second connecting piece 4. For example, in order to better connect the first connecting piece 1 and the second connecting piece 4, the outer diameter of the protruding part 12 of the first connecting piece 1 can be slightly larger than the inner diameter of the accommodating cavity 41; in this case, in order to better insert the first connecting piece 1 into the accommodating cavity 41, a guide part 13 can be arranged on the protruding part 12 of the first connecting piece 1, the outer diameter of the guide part 13 gradually increases from the end close to the second connecting piece 4 to the end away from the second connecting piece 4, the outer diameter of the end of the guide part 13 close to the second connecting piece 4 is slightly smaller than the inner diameter of the accommodating cavity 41, and the outer diameter of the end of the guide part 13 away from the second connecting piece 4 is slightly larger than the inner diameter of the accommodating cavity 41, thereby facilitating the insertion of the first connecting piece 1 into the accommodating cavity 41 through the guide part 13, realizing the cooperation of the protruding part 12 and the recessed part 42, and ensuring the connection between the first connecting piece 1 and the second connecting piece 4.
[0050] In some embodiments, referring to Figure 1 、 Figure 4 、 Figure 8 and Figure 9 , the protruding part 12 is configured to rotate relative to the recessed part 42. For example, when the first connecting piece 1 of the surgical lamp is inserted into the accommodating cavity 41 of the second connecting piece 4, the protruding part 12 slides into the recessed part 42; when the surgical lamp needs to be rotated according to the operation, the rotation of the first connecting piece 1 relative to the second connecting piece 4 can be realized, and the protruding part 12 rotates in the recessed part 42 when the first connecting piece 1 rotates relative to the second connecting piece 4; at the same time, the elastic member 2 is sleeved in the annular groove 11, the buffer member 3 is sleeved on the elastic member 2, and the buffer member 3 always abuts against the inner wall of the accommodating cavity 41. When the external driving force is greater than the friction force between the buffer member 3 and the inner wall of the accommodating cavity 41, the first connecting piece 1 rotates relative to the second connecting piece 4; when the rotation stops, the buffer member 3 always abuts against the inner wall of the accommodating cavity 41, the buffer member 3 and the inner wall of the accommodating cavity 41 have a friction force, and the first connecting piece 1 is prevented from shaking relative to the second connecting piece 4, that is, the surgical lamp is prevented from shaking.
[0051] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
