Description

Technical Field

[0001] The present application relates to the technical field of lighting fixtures, and in particular to a dimmable classroom eye protection lamp. Background Art

[0002] The hanging structure of the classroom eye protection lamp usually includes lamps, hangers and connecting parts. The lamp is the main part of the eye protection lamp, including lampshade, light source and control device. The lampshade is usually made of materials with good light transmittance, such as acrylic, which can make the light evenly illuminate the interior of the classroom while reducing glare and dazzling. The hanger is a component used to fix the lamp, usually made of metal material, with a certain load-bearing capacity and durability. The connecting part is a component used to connect the hanger and the lamp together, generally made of metal material, with a certain strength and durability.

[0003] During use, when wind blows or external force acts on the suspended lamp, the lamp will shake as a whole due to the installation method of the hanging lamp, causing the connector to become loose and deformed. The shaking of the lamp will also cause the irradiated aperture to shake, affecting the stability of the light source. Utility Model Content

[0004] The present application proposes a dimmable classroom eye protection lamp, which has the advantage of being more stable in use and is used to solve the problem of shaking due to external force during use proposed in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a dimmable classroom eye-protection lamp, comprising a ceiling wall, the bottom surface of the ceiling wall is connected to a suspension rod through a saddle buckle, and the ceiling wall is connected to the top of the lamp body through the suspension rod, the outer side of the suspension rod is movably clamped with a fixing box through a clamping ring, the inner two sides of the fixing box are respectively connected with a rotating shaft I and a rotating shaft II, and the outer sides of the rotating shaft I and the rotating shaft II are respectively connected with a fixed wheel II and a fixed wheel V, a traction rope I is wrapped around the outer sides of the fixed wheel II and the fixed wheel V, and one end of the traction rope I is fixedly connected to the outer side of the fixed wheel II, and the other end of the traction rope I extends out of the fixing box and is connected to the bottom end of the ceiling wall, the end face of the fixed wheel II is connected with a fixed head I, and a vertically sliding abutment plate is provided above the fixed head I through a fixed spring, and the end of the abutment plate extends out of the top surface of the fixing box.

[0006] Furthermore, the cross-section of the fixing box is rectangular, and the circumferential side surface of the fixing box is parallel to the circumferential side surface of the lamp body.

[0007] Furthermore, the rotating shaft I and the rotating shaft II are axially parallel, and the traction rope I is wound counterclockwise around the outer sides of the fixed wheel II and the fixed wheel V.

[0008] Furthermore, the fixing head I is located at the end of the fixing wheel II close to the axis direction of the boom, and the axis of the fixing head I is located above the axis of the fixing wheel II.

[0009] Furthermore, the outer sides of the rotating shafts I and II are respectively connected with fixed wheels III and IV, and the outer sides of the fixed wheels III and IV are wound with traction ropes II, and the end of the traction rope II is connected with a fixed head II close to the fixed wheel V, the fixed wheel II, the fixed wheel V, the traction rope I and the fixed head I are a whole, the fixed wheel III, the fixed wheel IV and the traction rope II and the fixed head II are a whole, and the fixed wheel II, the fixed wheel V, the traction rope I and the fixed head I are symmetrical with the fixed wheel III, the fixed wheel IV, the traction rope II and the fixed head II relative to the center of the circle of the suspension rod, and the abutment plate and the fixing spring are distributed at equal angles at the top of the fixing box.

[0010] Furthermore, the rotating shaft I, rotating shaft II, fixed wheel II, fixed wheel V, traction rope I, fixed head I, fixed wheel III, fixed wheel IV, traction rope II and fixed head II are integrally formed as an adjustment assembly, and two groups of adjustment assemblies are provided on the inner side of the fixed box, and the two ends of the rotating shaft I in the two groups of adjustment assemblies correspond to adjacent right-angle surfaces in the fixed box respectively.

[0011] The beneficial effect of the utility model is that through the setting of the fixing box, when the lamp body shakes, the top end of the support plate will directly resist the bottom end of the saddle buckle or the top wall, thereby reducing the force between the lamp body and the top wall through the hanger and the fixing box and its connecting parts during shaking, thereby protecting the stable installation of the connecting parts.

[0012] Through the setting of the support plate, when shaking, the bottom end of the support plate can push the fixed head I or the fixed head II to move, and then drive the fixed wheel II or the fixed wheel IV to rotate, so that the fixed wheel II rotates and wraps around the traction rope I, and then the top wall is directly pulled through the other end of the traction rope I, so that when the fixed box as a whole shakes to one side, the traction rope I can directly pull the fixed box on the opposite side to reset it, which facilitates the process of quickly resetting the lamp body after shaking, reduces the degree of influence on the use of the light source when the lamp body shakes, and improves the comfort of use.

When the lamp body 4 shakes toward the side of a fixed head Ⅰ11, the butt plate 12 above the fixed head Ⅰ11 will be resisted by the top riding buckle 2 and extend into the inside of the fixed box 5, so that the end of the butt plate 12 pushes the fixed head Ⅰ11 to drive the fixed wheel Ⅱ8 to rotate, so that the fixed wheel Ⅱ8 rotates clockwise to wrap around the traction rope Ⅰ10, so that the other end of the traction rope Ⅰ10 directly pulls the top wall 1 on the other side of the shaking, which is convenient for the lamp body 4 to shake and reset, thereby improving the reset efficiency.

[0023] See also Figure 2 and Figure 3 The cross-sectional shape of the fixing box 5 is rectangular, and the circumferential side surfaces of the fixing box 5 are parallel to the circumferential side surfaces of the lamp body 4. Because the lamp body 4 is arranged in the classroom, and the transverse surface of the lamp body 4 is parallel to the classroom window surface, the wind direction blowing into the room through the window is not perpendicular to the window. Therefore, the circumferential side surfaces of the fixing box 5 are parallel to the circumferential side surfaces of the lamp body 4, so that the shape of the fixing box 5 determines the orientation of the inner structure, and then the shape and orientation of the fixing box 5 can make the inner structure better receive the wind shaking of the transverse side surfaces of the lamp body 4 caused by the external environment, thereby improving the effectiveness of the effect. The cross-sectional shape of the fixing box 5 is set to be rectangular, so that when the fixing box 5 shakes relative to the top wall 1, the top surface of the fixing box 5 and the top wall 1 can directly resist each other, thereby receiving the shaking force and reducing the influence of excessive shaking.

[0028] The usage method (working principle) of the utility model is as follows:

[0029] When the lamp body 4 is shaken by external force, the lamp body 4 shakes toward the side close to the fixed head Ⅰ11, and the movement of the lamp body 4 drives the suspension rod 3 to move, and then the fixed box 5 moves with the movement of the suspension rod 3, so that the fixed box 5 can move and drive the top of the support plate 12 on the shaking side to approach the upper saddle buckle 2 or the top wall 1, so that the support plate 12 is pushed to the inside of the fixed box 5 and push the fixed head Ⅰ11 to move downward, so that the fixed head Ⅰ11 drives the fixed wheel Ⅱ8 to rotate clockwise, so that the fixed wheel Ⅱ8 rotates to wrap more traction rope Ⅰ10, so that the fixed wheel Ⅱ8 on the shaking side The end of the traction rope Ⅰ10 in the opposite direction directly pulls the top wall 1 on the outside of the fixed wheel Ⅴ9, so that the fixed box 5 is subjected to the pulling force of the traction rope Ⅰ10 to resist the external force that causes the fixed box 5 to shake. At the same time, the rotation of the fixed wheel Ⅱ8 will drive the fixed wheel Ⅲ14 on the other side to rotate through the rotating shaft Ⅰ6, and then the outside of the fixed wheel Ⅲ14 rotates to pull the traction rope Ⅱ16 on the outside of the fixed wheel Ⅳ15, and then the fixed wheel Ⅳ15 is driven to rotate again through the traction rope Ⅱ16, so that the fixed wheel Ⅳ15 helps the rotating shaft Ⅱ7 to rotate, and the traction rope Ⅰ10 pulls the fixed box 5 to quickly reset.
