Technical Field

[0001] This utility model relates to the field of liquid crystal display manufacturing technology, and in particular to a lamp with a fixed bracket. Background Technology

[0002] In the display industry, each stage of the display manufacturing process requires visual and electrical testing. Illuminance testing must strictly adhere to customer requirements. Traditionally, illuminance testing is performed before production; however, during production, the lights controlling illuminance can be subject to variations due to accidental movement by personnel. This can lead to situations where overly strict inspection standards result in good products being deemed defective, wasting costs, or overly lenient standards fail to meet customer needs, leading to complaints. Therefore, effectively controlling lamp position variations is crucial. Furthermore, the same lamp cannot be shared across different workstations due to varying work surface dimensions.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] See Figure 1 This diagram illustrates the structure of a lamp with a fixed bracket according to the first embodiment of the present invention. Generally, it includes a clamping assembly 1, which can be an I-beam clamp or a spring clamp, etc. A fixed support column extends outward from one side of the clamping assembly 1, and the support column is cylindrical. A base 2 is mounted on the side of the clamping assembly 1 located on the fixed support column. A groove is provided on one side of the base 2, and the base 2 is rotatably connected and fixed to the fixed support column through the groove. A fixing screw is provided on one side of the base 2, and the fixing screw enables the base 2 and the clamping assembly 1 to form a detachable fixed connection. A bracket assembly is rotatably connected to the base 2, wherein the bracket assembly includes a rotatably connected first... A first connecting rod 3 and a second connecting rod 4 are provided. One end of the first connecting rod 3 is hinged to the base 2, and the other end is rotatably connected to the second connecting rod 4. A locking assembly 6 is provided between the first connecting rod 3 and the second connecting rod 4. The locking assembly 6 can lock the rotatable connection between the two connecting rods after they have been rotated a certain angle. A lamp 5 is rotatably connected to the other end of the second connecting rod 4. Adjusting the angle between the first connecting rod 3 and the second connecting rod 4 can change the distance between the lamp 5 and the base 2 to adapt to different workstation illuminance detection. Furthermore, by connecting the lamp 5 to the bracket assembly, the lamp 5 is more stable relative to the workstation, preventing illuminance variations due to shaking and improving product inspection yield.

[0028] See Figure 2 Furthermore, the first connecting rod 3 includes a rotating part hinged to the base 2, and a tail portion near the rotating part. The tail portion is provided with an adjustment mechanism, which includes a dial 31. The dial 31 is cylindrical and rotatably connected inside the first connecting rod 3. Figure 2It can be seen that the outer diameter of the dial wheel 31 is larger than the thickness of the first connecting rod 3. Understandably, the dial wheel 31 is designed to penetrate the first connecting rod 3, allowing its outer portion to protrude from one side of the first connecting rod 3 for external rotation. A cavity is provided inside the dial wheel 31, and two push rods 32 are threadedly connected within this cavity along the axial direction of the dial wheel 31. Under the rotation of the dial wheel 31, the two push rods 32 slide towards each other along the inner wall of the first connecting rod 3. A receiving cavity 33 is provided on the side of the push rods 32 away from the dial wheel 31, with one end penetrating one side of the first connecting rod 3. A steel ball 34 is placed inside the receiving cavity 33, allowing it to slide within. Understandably, the receiving cavity 33 has a cylindrical structure with a diameter equal to that of the steel ball 34. Several through holes 21 adapted to the steel ball 34 are provided on the base 2. In actual use, the first connecting rod 3 is rotated first to... The first connecting rod 3 rotates around the base 2 to a certain angle. Then, by rotating the dial 31, the push rod 32 moves away from the dial 31, pushing the steel ball 34 outward and limiting it between the receiving cavity 33 and the through hole 21, preventing the first connecting rod 3 from rotating around the base 2. It is understood that the diameter of the through hole 21 is smaller than the diameter of the steel ball 34. It should be noted that designing the diameter of the through hole 21 to be smaller than the diameter of the steel ball 34 also facilitates the rotation of the first connecting rod 3 after the push rod 32 is released from limiting the steel ball 34. The base 2 pushes the steel ball 34, causing the steel ball 34 to enter the receiving cavity 33 and detach from the contact with the base 2, thereby unlocking the rotation lock between the first connecting rod 3 and the base 2. In addition, since the steel ball 34 rotates around the first connecting rod 3 and the base 2, several through holes 21 are spaced along the swing trajectory of the tail of the first connecting rod 3. The number of through holes 21 can be specifically set according to the structure of the base 2.

[0029] See Figure 2 Furthermore, a spring 35 can be installed inside the receiving cavity 33. The spring 35 is located on the side of the steel ball 34 near the push rod 32. Specifically, one end of the spring 35 abuts against the steel ball 34, and the other end abuts against the side wall of the receiving cavity 33. The spring 35 is always kept in a compressed state to push the steel ball 34 toward the through hole 21. During the adjustment of the angle of the first connecting rod 3, the steel ball 34 automatically slides into the through hole 21 and can provide feedback on this adjustment process to the user and quickly lock it. In addition, when locking is required, the dial 31 is rotated to push the push rod 32, so that the push rod 32 passes through the spring 35 and abuts against the steel ball 34.

[0030] See Figure 3The lamp 5 includes a lamp body 51 and a lamp holder 52 for supporting and fixing the lamp body 51. The lamp 5 is connected to one end of a second connecting rod 4 via one end of the lamp holder 52. A fixing component 7 is provided between the lamp holder 52 and the second connecting rod 4 to lock the rotation of the lamp holder 52 and the second connecting rod 4, thereby fixing the lamp 5 at a specific angle, for example, keeping the angle between the lamp 5 and the surface of the workstation fixed for illuminance testing. In this embodiment, the fixing component 7 includes a locking pin 71 with a cylindrical structure. The locking pin 71 includes a smooth rod portion 712 at one end and a threaded portion 711 at the other end. A handle 72 is provided at one end of the smooth rod portion. Figure 3 As shown, during assembly, the locking pin 71 passes through a portion of the lamp holder 52, then through one side of the second connecting rod 4. Finally, the threaded portion 711 of the locking pin 71 is threadedly connected to the other part of the lamp holder 52. It can be understood that the lamp holder 52 and the second connecting rod 4 are rotatably connected via the locking pin 71. It should be noted that as the handle 72 rotates, the threaded portion 711 of the locking pin 71 slowly rotates into the lamp holder 52. When one side of the handle 72 abuts against the side of the lamp holder 52, as the handle 72 continues to rotate, the lamp holder... The lamp holder 52 and the second connecting rod 4 are pressed together to achieve rotational locking between the lamp holder 52 and the second connecting rod 4, thereby locking the lamp 5 in one position and keeping it stationary. Obviously, this locking method is fixed by the static friction between one side surface of the lamp holder 52 and the second connecting rod 4. It can be understood that in order to improve the stability during locking and prevent relative sliding between the lamp 5 and the second connecting rod 4 due to insufficient static friction, in some embodiments, an anti-slip component with a high coefficient of friction, such as a hard rubber ring, is provided between the abutting surfaces of the lamp holder 52 and the second connecting rod 4. According to the above description, of course, the locking pin 71 can also be designed to first pass through part of the second connecting rod 4, then through the lamp holder 52, and finally be threadedly connected to another part of the second connecting rod 4.

[0031] See Figure 3 In this embodiment, the locking assembly 6 connected between the first connecting rod 3 and the second connecting rod has the same structure as the fixing assembly 7. It can be understood that the structure of the connection end between the first connecting rod 3 and the second connecting rod 4 is the same as the structure of one end of the lamp holder 52 and one end of the second connecting rod 4. By locking the rotation of the first connecting rod 3 and the second connecting rod 4 through the locking assembly 6, the distance between the lamp 5 and the base 2 assembly is changed to adapt to the illumination detection of workstations of different lengths.

[0032] In summary, the lamp with a fixed bracket in the above embodiments of this utility model can lock the rotation angle of the second connecting rod relative to the base by setting a dial, push rod, spring, and steel ball at one end of the second connecting rod near the base, and cooperating with the through hole set on the base; a locking assembly between the first and second connecting rods allows the distance between the lamp and the base, as well as the height of the lamp, to be changed by locking the angle between the first and second connecting rods, so as to adapt to the illuminance measurement of workstations of different sizes; the fixed assembly between the lamp and the second connecting rod facilitates the adjustment of the lamp's illumination angle; and the entire lamp is fixed to the workstation by the clamping assembly, making the lamp more stable relative to the workstation and preventing shaking, thereby improving the accuracy of judging and testing products.

[0033] See Figure 4 The image shows a lamp with a fixed bracket in the second embodiment of this utility model. The first connecting rod 3 and the second connecting rod 4 are rotatably connected. Specifically, the locking assembly 6 located between the first connecting rod 3 and the second connecting rod 4 includes a locking bar 61 movably connected to one end of the second connecting rod 4. A slot 611 is formed on the locking bar 61, and the slot 611 is elongated along the length of the locking bar 61. A screw 62 is located on the same side of the first connecting rod 3 and the locking bar 61. The screw 62 passes through the slot 611 and is threadedly connected to the first connecting rod 3, thus movably connecting the locking bar 61 to one side of the first connecting rod 3. Adjusting the first connecting rod 3... When the rotation angle between the first connecting rod 3 and the second connecting rod 4 is adjusted, the screw 62 can slide within the slot 611. When it is necessary to lock the angle between the first connecting rod 3 and the second connecting rod 4, simply tighten the screw 62 to lock the movable connection between the locking bar 61 and the second connecting rod 4, thereby locking the angle adjustment between the first connecting rod 3 and the second connecting rod 4, and thus changing the distance between the lamp 5 and the base 2. In addition, it is understood that the locking bar 61 can also be movably connected to the first connecting rod 3. Specifically, it can be set on the first connecting rod 3 and the second connecting rod 4. Those skilled in the art can design it according to the actual situation, and it is not limited to being set only on the second connecting rod 4 in this application.

[0034] See Figure 5 The lamp 5 with a fixed bracket in the third embodiment of the present utility model has the same structure as the locking component 6 and the fixing component 7, and both include a connecting block 64 and two locking pins 71. The locking pins 71 lock the rotational connection between the lamp holder 52, the first connecting block 64, the second connecting block 64 and the connecting block 64, thereby realizing the adjustment of the distance between the lamp 5 and the base 2, as well as the adjustment of the angle of the lamp 5.

[0035] Furthermore, the length of the connecting block 64 is equal to the sum of the thickness of the lamp holder 52 and the thickness of the second connecting rod 4. By setting the connecting block 64, the lamp holder 52 can be folded between the lamp holder 52 and the second connecting rod 4 by rotation. Of course, the first connecting rod 3 and the second connecting rod 4 can also be folded together through the connecting block 64, which facilitates the overall storage.
