Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically to a lamp clamping and fixing device. Background Technology

[0002] Working face lighting is essential for safe production and improved efficiency in mines. Good lighting not only ensures miners can see clearly in the complex and ever-changing underground environment, preventing accidental injuries, but is also a key factor in improving production efficiency and ensuring work quality.

[0003] Existing fixed lighting devices in mines generally adopt a suspended structure, which has obvious shortcomings: on the one hand, it is impossible to flexibly adjust the angle and height of the lamps, resulting in a limited lighting range and making it difficult to meet the needs of the changing working environment in mines; on the other hand, when it is necessary to move the lighting equipment or adjust the illumination angle, the existing devices show great limitations and rely on manual handling for movement, which not only greatly increases the labor intensity but also significantly affects work efficiency. Utility Model Content

[0004] This utility model proposes a quick-assembly and disassembly mobile lighting fixing device for work surfaces. Its purpose is to solve the problems of existing mobile lighting fixing devices being unable to quickly adjust the illumination angle and lamp installation height, as well as their poor mobility.

[0005] The technical solution of this utility model is as follows:

[0006] A quick-release mobile lighting fixing device for work surfaces includes a frame, which includes a crossbar and support rods. The support rods include first support rods extending backward at the left and right ends of the crossbar, and a second support rod extending forward at the angle between the two first support rods. The crossbar, the two first support rods, and the second support rod together form a triangular support structure. Three sleeves with fastening bolts are fitted onto the crossbar. The fastening bolts can pass through the sidewalls of the sleeves and contact the crossbar body. A positioning ring is fixed to the middle sleeve, and an adjusting bolt is provided on one side of the positioning ring. The second support rod passes through the positioning ring. A quick-release clamping seat is also included, rotatably connected to the crossbar. The quick-release clamping seat includes a base plate, a fixing plate on the left side of the base plate, a back plate on the rear side of the base plate, a connecting plate that slides onto the base plate on the right side of the back plate, and a rotating clamping plate on the right side of the base plate. The rotating clamping plate is rotatably connected to the connecting plate of the quick-release clamping seat via a rotating shaft. The connecting plate is fixed to the right sleeve, and the back plate is fixed to the left sleeve. A torsion spring is fitted on the rotating shaft. One torsion arm of the torsion spring is fixed to the inner wall of the back plate, and the other torsion arm is fixed to the inner wall of the rotating clamping plate.

[0007] As a further improvement, the connecting plate and the rotating clamping plate are rotatably connected by a rotating shaft. A groove is provided on the inner wall of the right side of the connecting plate. The groove is in concave-convex fit with the protrusion at the rear end of the rotating clamping plate. The protrusion is provided with a through hole for the rotating shaft to pass through. A hole is provided on the bottom surface of the groove to fit with the rotating shaft.

[0008] As a further improvement, a movable component installed at the bottom of the support rod is also included.

[0009] As a further improvement, the movable component includes casters, which are mounted on the bottom end of the support rod via a base plate. A support plate is fixed to the lower side of the base plate, and the casters are rotatably connected between the two support plates via axles.

[0010] As a further improvement, the movable component also includes a stop mechanism to prevent the casters from rolling. The stop mechanism is fixed to the outside of the support plate. A rotating rod is threaded onto the stop mechanism. A fixing strip is rotatably connected to the inner end of the rotating rod. The fixing strip is slidably connected in the grooves on both sides of the positioning frame. A handle is fixed to the rotating rod after it passes through the outer horizontal plate.

[0011] As a further improvement, the upper end of the connecting plate is provided with a detachable connecting block, and the bottom surface of the connecting block is provided with a round hole that mates with the rotating shaft.

[0012] As a further improvement, both the fixed plate and the rotating clamping plate have stops at their front ends to prevent the lamp from slipping forward.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] (1) This device is a triangular support structure consisting of a crossbar, a first support rod fixed at both ends of the crossbar extending forward at an angle, and a second support rod slidably connected between the two first support rods and extending backward at an angle via a positioning ring. By adjusting the adjusting bolt on the positioning ring, the fixed position of the second support rod is changed, thereby adjusting the included angle between the first and second support rods to achieve the purpose of adjusting the height of the frame. At the same time, by rotating the quick-release clamping seat installed on the crossbar, the illumination angle of the lamp can be infinitely adjusted to ensure uniform illumination on the working surface. The sleeve is connected to a fastening bolt that can contact the crossbar. By adjusting the fastening bolt, the sleeve and the crossbar can be locked and unlocked. Furthermore, by rotating the clamping plate driven by a torsion spring, the lamp can be quickly disassembled and assembled, improving maintenance efficiency.

[0015] (2) The device can move quickly by setting up a moving part, which saves time and effort, reduces labor intensity and improves work efficiency. At the same time, the moving part is equipped with a threaded drive stop mechanism to avoid the problem of easy wear of traditional brake parts and extend service life. Attached Figure Description

[0022] The technical solution and effects of this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0023] like Figure 1 An embodiment of a quick-release mobile lighting fixing device for work surfaces includes a frame 1, a quick-release clamping seat 2, and a movable component 3.

[0024] Combination Figure 2 The frame 1 includes a crossbar 11 and support rods. The support rods include first support rods 12 that are fixed to the left and right ends of the crossbar 11 and extend obliquely backward, and second support rods 14 that are disposed between the two first support rods 12 and extend obliquely forward. The crossbar 11, the two first support rods 12 and the second support rod 14 together form a triangular support structure.

[0025] Combination Figure 3 Three sleeves 21 with fastening bolts 22 are fitted onto the crossbar 11. The fastening bolts 22 can pass through the side wall of the sleeve 21 and contact the crossbar 11. Tightening the fastening bolts 22 can tighten the crossbar 11, thereby locking the sleeves 21 and the crossbar 11. A positioning ring 13 is fixed on the middle sleeve 21. An adjusting bolt is provided on one side of the positioning ring 13. The second support rod 14 is set through the positioning ring 13. The angle between the first support rod 12 and the second support rod 14 can be changed by adjusting the fixed position of the second support rod 14 and the positioning ring 13, thereby adjusting the height of the frame 1.

[0026] like Figure 3 The quick-release clamping base 2 includes a base plate, a fixing plate 23 on the left side of the base plate, a back plate 28 on the rear side of the base plate, and a connecting plate 281 that slides onto the base plate on the right side of the back plate 28. A rotating clamping plate 24 is located on the right side of the base plate, and is rotatably connected to the connecting plate 281 of the quick-release clamping base 2 via a rotating shaft 27. Both the fixing plate 23 and the rotating clamping plate 24 have stops at their front ends to prevent the lamp from slipping forward. The connecting plate 281 is fixed to the sleeve 21 on the right side, and the back plate 28 is fixed to the sleeve 21 on the left side.

[0027] When adjusting the angle of the quick-release clamp 2, loosen the fastening bolt 22, rotate the sleeves 21 on both sides to drive the quick-release clamp 2 to rotate around the axis of the crossbar 11 to a suitable angle, and then tighten the fastening bolt 22 so that the fastening bolt 22 presses against the crossbar 11. The rotating clamping plate 24 and the connecting plate 281 are rotatably connected by a rotating shaft 27. A torsion spring is sleeved on the rotating shaft 27. One torsion arm of the torsion spring is fixed to the inner wall of the back plate 28, and the other torsion arm is fixed to the inner wall of the rotating clamping plate 24. A groove 26 is opened on the inner wall of the right side of the connecting plate 281. The rotating clamping plate 24 has a protrusion 25 at the rear end that engages with the corresponding groove 26. The protrusion 25 has a through hole for the rotating shaft 27 to pass through, and the bottom surface of the groove 26 has a hole that engages with the rotating shaft 27. A detachable connecting block is provided at the upper end of the connecting plate 281. The bottom surface of the connecting block has a hole that engages with the rotating shaft 27. During installation, first insert the protrusion 25 into the groove 26, then insert the rotating shaft 27 into the shaft hole corresponding to the protrusion 25 and the groove 26, and finally fix the connecting block to the upper end of the connecting plate 281.

[0028] like Figure 1 and Figure 4 The movable component 3 includes casters 33, which are mounted on the bottom end of the support rod via a base plate 31. A support plate 32 is fixed to the lower side of the base plate 31, and the casters 33 are rotatably connected between the two support plates 32 via axles.

[0029] As a further improvement to this utility model, such as Figure 4 The movable component 3 also includes a stop mechanism to prevent the caster 33 from rolling. The stop mechanism includes a positioning frame 34 fixed to the outside of the support plate 32. A rotating rod 36 is threadedly connected to the outer horizontal plate of the positioning frame 34. A fixing strip 35 is rotatably connected to the inner end of the rotating rod 36. The fixing strip 35 is slidably connected in the grooves on both sides of the positioning frame 34 to prevent the fixing strip 35 from rotating with the rotating rod 36 when it moves, thus affecting the fixing effect of the fixing strip 35 on the caster 33.

[0030] Furthermore, the lever 36 is fixed with a handle after passing through the outer cross plate.

[0031] Optionally, the side of the fixing strip 35 that contacts the caster 33 is provided with an anti-slip rubber pad to increase the friction between the fixing strip 35 and the caster 33 and prevent slippage.

[0032] Assembly process:

[0033] First, the sleeve 21 with the positioning ring 13 fixed is fitted onto the crossbar 11, and then a sleeve 21 is fitted onto the left and right sides of the sleeve 21 respectively. Next, the connecting plate 281 and the rotating clamping plate 24 are connected by the rotating shaft 27, and the connecting block is fixed to the upper end of the connecting plate 281 with screws. Then, the clamping base back plate 28 is fixedly connected to the left sleeve 21, and the connecting plate 281 is fixedly connected to the right sleeve 21. The second support tube is passed through the positioning ring 13 and the fastening bolt 22 is tightened. The two first support rods 12 are fixed to the left and right ends of the crossbar 11 respectively. Finally, the moving part 3 is installed at the lower end of the support rod, completing the assembly of this embodiment.

[0034] In use, rotate the clamping plate 24 outwards, at which point the torsion spring tightens. Then, place the lamp fixture inside the quick-release clamping seat 2. Next, release the clamping plate 24. Under the action of the torsion spring, the clamping plate 24 rotates inwards to its initial position, clamping the lamp fixture together with the fixing plate 23 inside the quick-release clamping seat 2. When it is necessary to adjust the lamp fixture angle, loosen the fastening bolts 22 on the left and right sleeves 21, rotate, adjust the lamp fixture to the appropriate angle, and then tighten the fastening bolts 22 to press against the crossbar 11, locking the quick-release clamping seat 2 to the crossbar 11. Pushing the frame 1 causes the casters 33 to roll, enabling the frame 1 to move quickly. When locking is required, turn the rotating rod 36 to press the fixing strip 35 down against the wheel surface of the caster 33, increasing friction to prevent it from rolling and completing the locking.

[0035] It should be noted that, as will be apparent to those skilled in the art, this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. The scope of this utility model is defined by the claims rather than the foregoing description.
