Description

Technical Field

[0001] The utility model relates to the technical field of installation of evacuation indicator lamps, in particular to a height-adjustable evacuation lamp fixing bracket. Background Art

[0002] Evacuation lamps are suitable for emergency lighting and reminders. They are the most common lighting tools in fire emergencies. They have long emergency time, high brightness, and automatic emergency function during power outages. They are suitable for use in public places such as factories, hotels, schools, and units for emergency evacuation reminders.

[0003] At present, in the prior art, for example, a Chinese patent with a publication number of CN216596802U discloses a device for fixing an evacuation indicator light on a cylinder, wherein the middle part of an elastic mounting plate is connected to a mounting frame, and both ends are connected to the mounting frame through elastic components respectively; when installed on cylinders of different diameters, the elastic mounting plate is bent to adapt to cylinders of different diameters, and the stability of the connection between the mounting frame and the elastic mounting plate is ensured. However, after the device is installed, the height is locked, resulting in the need to use a ladder for auxiliary work during replacement and maintenance work, making the maintenance work cumbersome. In view of this, we propose a height-adjustable evacuation lamp fixing bracket. Utility Model Content

[0004] The main purpose of the utility model is to provide a height-adjustable evacuation lamp fixing bracket, which can solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes a height-adjustable evacuation lamp fixing bracket, comprising a mounting frame, the bottom of which is fixedly connected to a limit plate, a card slot is provided on the mounting frame, and an adjustment structure is slidably connected to the outer wall of the mounting frame, and the adjustment structure comprises:

[0006] An adjustment seat, the outer wall of the mounting frame is slidably connected with the adjustment seat;

[0007] A sliding block, wherein the inner wall of the adjusting seat is slidably connected with the sliding block;

[0008] A connecting rod is hingedly connected to the bottom of the sliding block.

[0009] Preferably, an inclined slide groove is provided on the adjustment seat, and an inclined limit groove is provided on the mounting frame. The inner wall of the inclined slide groove is slidably connected to a limit slider. Both the inclined limit groove and the inclined slide groove are circular in design, and the aperture of the inclined limit groove is larger than that of the inclined slide groove.

[0010] Preferably, one end of the connecting rod away from the sliding block is hinged on the outer wall of the limiting sliding block, and the top of the sliding block is fixedly connected with a counterweight block. The gravity of the counterweight block drives the sliding block to slide on the inner wall of the adjusting seat, thereby driving the connecting rod to move.

[0011] Preferably, a sliding hole is provided at the bottom of the adjustment seat, a sliding rod is slidably connected to the inner wall of the sliding hole, and a threaded hole is provided on the outer wall of the adjustment seat. The sliding block is moved through the sliding hole to make the sliding rod slide in the sliding hole.

[0012] Preferably, the top of the sliding rod is fixedly connected to the sliding block, and the bottom of the sliding rod is fixedly connected to a force plate. The sliding rod can be easily slid in the sliding hole by pushing the force plate. The larger force plate makes it easier for workers to push with a rod.

[0013] Preferably, an evacuation light is slidably connected to the outer wall of the adjustment seat, and a mounting ear is provided on the back of the evacuation light. A through hole is provided on the mounting ear, and a fixing bolt passes through the through hole and is threaded into the threaded hole to complete the fixed connection between the mounting ear and the adjustment seat, so that the evacuation light completes the fixed installation work.

[0014] The utility model provides a height-adjustable evacuation lamp fixing bracket, which has the following beneficial effects:

[0015] (1) The height-adjustable evacuation lamp fixing bracket uses an ordinary rod to push the force plate, which moves upward through the force plate, driving the sliding rod and the sliding block to move upward, driving the limit slider to leave the mounting frame, at which time the bottom of the force plate contacts the bottom of the adjustment seat, and the rod is slowly moved downward, so that the adjustment seat begins to slide downward on the mounting frame, thereby changing the height of the evacuation lamp. The limit plate allows the adjustment seat to stay on the mounting frame, making it convenient for workers to perform maintenance and inspection work on the device. The maintenance and inspection work of the device can be completed without the cooperation of a ladder, which is convenient and quick.

[0016] (2) After the maintenance work of the height-adjustable evacuation lamp fixing bracket is completed, the force plate is pushed upward by the rod, driving the adjustment seat to move on the mounting frame. When it moves to the appropriate height, we move the top of the rod from the bottom of the force plate to the bottom of the adjustment seat, and then move it downward slowly for a short distance. The gravity of the counterweight block causes the sliding block to slide downward, allowing the limit slider to enter the inclined limit groove, completing the limit work of the adjustment seat, so that one person can complete the maintenance and inspection work of the device, and also avoids the danger of high-altitude operations.

[0025] See also Figure 1-Figure 4The utility model proposes a height-adjustable evacuation lamp fixing bracket, including a mounting frame 1, the interior of the mounting frame 1 is hollow, which reduces the weight of the mounting frame 1, and is provided with a mounting hole, which runs through the mounting frame 1 to facilitate the installation of the fixing bolts, and the bottom of the mounting frame 1 is fixedly connected to a limiting plate 2, through which the limiting plate 2 is convenient for the adjustment seat 41 to be conveniently repaired on the limiting plate 2, and a card slot 3 is provided on the mounting frame 1, and the outer wall of the adjustment seat 41 is slidably connected to the inner wall of the card slot 3, and the card slot 3 is arranged on two sides of the mounting frame 1, so as to limit the adjustment seat 41, and an adjustment structure 4 is slidably connected to the outer wall of the mounting frame 1, and the adjustment structure 4 includes an adjusting seat 41, and the outer wall of the mounting frame 1 is slidably connected to the adjusting seat 41, and the inner wall of the adjusting seat 41 is slidably connected to a sliding block 42, and the bottom of the sliding block 42 is hinged with a connecting rod 43.

[0026] In the utility model, in order to limit the adjustment seat 41, an inclined slide groove 5 is arranged on the adjustment seat 41, and an inclined limiting groove 6 is arranged on the mounting frame 1. The inner wall of the inclined slide groove 5 is slidably connected with a limiting slider 44. The inclined limiting groove 6 and the inclined slide groove 5 are both circular in design, and the aperture of the inclined limiting groove 6 is larger than that of the inclined slide groove 5, so that the limiting slider 44 can enter the inclined limiting groove 6 conveniently, and then the adjustment seat 41 is fixed on the mounting frame 1. The end of the connecting rod 43 away from the sliding block 42 is hinged on the outer wall of the limiting slider 44, and the top of the sliding block 42 is fixedly connected with a counterweight block 45. The gravity of the counterweight block 45 drives the sliding block 42 to slide on the inner wall of the adjustment seat 41, thereby driving the connecting rod 43 to move.

[0027] Furthermore, a sliding hole is provided at the bottom of the adjusting seat 41, and a sliding rod 46 is slidably connected to the inner wall of the sliding hole, and a threaded hole 7 is provided on the outer wall of the adjusting seat 41. The sliding block 42 is moved through the sliding hole to make the sliding rod 46 slide in the sliding hole. The top of the sliding rod 46 is fixedly connected to the sliding block 42, and the bottom of the sliding rod 46 is fixedly connected to a force plate 47. By pushing the force plate 47, the sliding rod 46 can be easily slid in the sliding hole. The larger force plate 47 is convenient for workers to use a rod to push. The outer wall of the adjusting seat 41 is slidably connected to an evacuation lamp 8, and a mounting ear 9 is provided on the back of the evacuation lamp 8. A through hole 10 is provided on the mounting ear 9. A fixing bolt passes through the through hole 10 and is threaded into the threaded hole 7 to complete the fixed connection between the mounting ear 9 and the adjusting seat 41, so that the evacuation lamp 8 completes the fixed installation work.

[0028] When in use, the mounting frame 1 is conveniently fixed on the surface of the wall through the mounting holes on the mounting frame 1. When people need to adjust the height of the evacuation lamp 8, the force plate 47 is pushed by a common rod, and the force plate 47 moves upward, driving the sliding rod 46 and the sliding block 42 to move upward. At this time, the movement of the sliding block 42 drives the limit slider 44 to leave the mounting frame 1 through the hinged connecting rod 43. At this time, the bottom of the force plate 47 contacts the bottom of the adjustment seat 41. By slowly moving the rod downward, the adjustment seat 41 starts to slide downward on the mounting frame 1, thereby changing the height of the evacuation lamp 8. The adjustment seat 41 is stopped on the mounting frame 1 through the limit plate 2, which is convenient for workers to maintain and repair the device.

[0029] When the inspection and maintenance work is completed, the force plate 47 is pushed upward by the rod, driving the adjustment seat 41 to move on the mounting frame 1. When it moves to a suitable height, we move the top of the rod from the bottom of the force plate 47 to the bottom of the adjustment seat 41, and then move it downward slowly for a short distance. The sliding block 42 slides downward by the gravity of the counterweight block 45 itself, and the limiting slider 44 enters the inclined limiting groove 6 through the connecting rod 43 to complete the limiting work of the adjustment seat 41. It is convenient and quick, and the maintenance and inspection work of the device can be completed without the cooperation of a ladder, and the danger of high-altitude operations is avoided.
