Technical Field
[0001] The utility model relates to the technical field of mechanical tools, in particular to a test tool for emergency lighting lamps. Background Art
[0002] With the increasing annual demand for emergency lighting lamps, the national technical parameter requirements for emergency lighting lamps are more stringent. According to the regulations of "Fire Emergency Lighting and Evacuation Indication System" (GB17945-2010), fire emergency lighting lamps should have a manual self-check function. At present, the installed emergency lighting lamps (except for the centralized control type) are all equipped with self-check buttons, and the self-check buttons are manual test buttons, which are used to test whether the emergency lighting lamps can work normally under normal circumstances. By pressing this button, emergency situations such as power outages can be simulated to forcibly start the emergency lighting lamps, so as to check whether the performance parameters such as brightness and irradiation range are normal. However, since the installation height of emergency lighting lamps is usually more than 2 meters, and most exceed 2.5 meters, during daily inspections, due to the too high height of the self-check buttons, it brings inconvenience to the inspection work.
[0003] The traditional manual test method has many deficiencies, such as cumbersome testing, dangerous operation process, slow testing speed, low efficiency, etc. To ensure the quality of emergency lamp products, there is an urgent need for a test tool for the overall function of emergency lamps with a simple and efficient test method. Summary of the Utility Model
[0004] The utility model aims at the deficiencies of the existing technology and provides a test tool for emergency lighting lamps.
[0005] The technical solution for the utility model to solve the above technical problems is as follows:
[0006] A test tool for emergency lighting lamps includes an outer sleeve. On opposite sides of the top end of the outer sleeve, a first clamping chuck and a second clamping chuck are respectively provided.

Detailed implementation manners
[0027] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.
[0028] An embodiment of the present utility model discloses a test tool for an emergency lighting lamp.
[0029] Referring to Figures 1-4 , a test tool for an emergency lighting lamp includes an outer sleeve 1. On opposite sides of the top end of the outer sleeve 1, a first clamping chuck 2 and a second clamping chuck 3 are respectively provided. The first clamping chuck 2 and the second clamping chuck 3 are used to clamp both ends of the emergency lighting lamp 4. A test head 5 is provided at the top end of the outer sleeve 1, and the test head 5 is used to press the self-check button 6.
[0030] When testing the emergency lighting lamp 4 at a high place, an operator holds the outer sleeve 1 by hand, supports the first clamping chuck 2 and the second clamping chuck 3 at both ends of the emergency lighting lamp 4. At this time, the first clamping chuck 2 and the second clamping chuck 3 are clamped at both ends of the emergency lighting lamp 4. The test head 5 is stably placed on one side of the emergency lighting lamp 4. Then, the operator operates the test head 5 to make the test head 5 press the self-check button 6 to test the emergency lighting lamp 4, realizing safe and simple test operation for the emergency lighting lamp 4.
[0031] The first clamping chuck 2 is connected to the outer sleeve 1 through a rotating rod 7. The rotating rod 7 is rotatably connected to the outer sleeve 1 through a connecting shaft 8. Both the fixed rod 9 and the rotating rod 7 are made of elastic materials. The second clamping chuck 3 is connected to the outer sleeve 1 through the fixed rod 9. The fixed rod 9 is inclined and fixedly connected to the outer sleeve 1. The rotating rod 7 and the fixed rod 9 are always located in the same plane. Both the first clamping chuck 2 and the second clamping chuck 3 are made of deformable materials.
[0032] When the operator holds the outer sleeve 1 and places the outer sleeve 1 in the vertical direction, the fixed rod 9 and the rotating rod 7 are inclined. The first clamping chuck 2 and the second clamping chuck 3 are supported in the vertical direction. The fixed rod 9 and the rotating rod 7 can undergo elastic deformation and can move within a certain range, enabling the first clamping chuck 2 and the second clamping chuck 3 to adapt to emergency lights 4 of different sizes within a small range.
[0033] The rotating rod 7 is rotatably connected to the outer sleeve 1 around the connecting shaft 8, thereby moving the first clamping chuck 2 and changing the clamping distance between the first clamping chuck 2 and the second clamping chuck 3, so that the first clamping chuck 2 and the second clamping chuck 3 can better adapt to emergency lights 4 of different sizes. Both the first clamping chuck 2 and the second clamping chuck 3 are made of deformable materials, so that when the first clamping chuck 2 and the second clamping chuck 3 clamp the emergency light 4, the housing of the emergency light 4 is not easily damaged.
[0034] The outer sleeve 1 is in the shape of a circular tube. A tension steel wire rope 10 and a wire rope pulley 11 are arranged inside the outer sleeve 1. The tension steel wire rope 10 is threaded through the outer sleeve 1. One end of the tension steel wire rope 10 passes out of the top end of the outer sleeve 1, and the other end of the tension steel wire rope 10 is located at the lower end of the outer sleeve 1. The wire rope pulley 11 is used to guide the tension steel wire rope 10. The tension steel wire rope 10 is connected to the rotating rod 7 through a connecting block 12. A return spring is fixedly arranged between the rotating rod 7 and the outer sleeve 1. When the return spring is in the natural state, the distance between the first clamping chuck 2 and the second clamping chuck 3 is the largest.
[0035] The operator changes the position of the lower end of the tension steel wire rope 10, so that the upper end of the tension steel wire rope 10 moves along the wire rope pulley 11, and the top end of the tension steel wire rope 10 pulls the rotating rod 7 to rotate through the connecting block 12. When the operator pulls the tension steel wire rope 10, the tension steel wire rope 10 pulls the rotating rod 7 to rotate the rotating rod 7 towards the direction close to the second clamping chuck 3. When the operator releases the tension steel wire rope 10, the tension steel wire rope 10 undergoes elastic deformation and has a tendency to return to the original state. At this time, the tension steel wire rope 10 automatically resets under the action of the elastic force of the return spring and the gravity of the first clamping chuck 2 and the rotating rod 7, so that the rotating rod 7 rotates away from the second clamping chuck 3.
[0036] A tensioning handwheel 13 is provided at the lower end of the outer sleeve 1. The tensioning handwheel 13 is fixedly connected to the bottom end of the tensioning steel wire rope 10. The tensioning handwheel 13 is used to drive the movement of the tensioning steel wire rope 10. The tensioning steel wire rope 10 can be wound around the outer wall of the tensioning handwheel 13 at most 5 times. Since the number of winding turns of the tensioning handwheel 13 on the tensioning steel wire rope 10 is not much, the tensioning steel wire rope 10 is not easy to knot during the movement. When the operator rotates the tensioning handwheel 13 forward, the bottom end of the tensioning steel wire rope 10 can be wound around the outer wall of the tensioning handwheel 13, thereby tensioning the tensioning steel wire rope 10. When the operator rotates the tensioning handwheel 13 in the reverse direction, the bottom end of the tensioning steel wire rope 10 can be separated from the outer wall of the tensioning handwheel 13. At this time, the tensioning steel wire rope 10 automatically resets under the action of the elastic force of the return spring and the gravity of the first clamping chuck 2 and the rotating rod 7, realizing the convenient control process of the tensioning steel wire rope 10.
[0037] A limiting block 15 and a tensioning steel wire rope 14 are arranged inside the outer sleeve 1. The limiting block 15 is located at the upper end of the outer sleeve 1 and is fixedly connected to the inner wall of the outer sleeve 1. An activity shaft 16 is arranged above the outer sleeve 1. The activity shaft 16 is connected to the limiting block 15. Limiting grooves are vertically formed on both sides of the limiting block 15. The tensioning steel wire rope 14 passes through the two limiting grooves. The upper end of the tensioning steel wire rope 14 is wound around the outer wall of the activity shaft 16. A driving rod 17 is fixedly connected to the tensioning steel wire rope 14 above the activity shaft 16. The test head 5 is connected to the tensioning steel wire rope 14 through the driving rod 17. When the tensioning steel wire rope 14 moves, the test head 5 and the driving rod 17 move together with the tensioning steel wire rope 14.
[0038] The limiting block 15 is placed at a fixed position, which can stably support the tensioning steel wire rope 14 at the required position and limit the movement track of the tensioning steel wire rope 14. The operator pulls one end of the tensioning steel wire rope 14 to make the top of the tensioning steel wire rope 14 move along the outer wall of the activity shaft 16. When the tensioning steel wire rope 14 moves, the test head 5 is driven to move through the driving rod 17, thereby realizing the movement control function of the test head 5.
[0039] A first connecting rod 18 is fixedly arranged on the limiting block 15. The first connecting rod 18 is arranged along the length direction of the outer sleeve 1. The activity shaft 16 is connected to the first connecting rod 18 through a second connecting rod 19. A receiving groove 20 is formed at the bottom end of the second connecting rod 19. The upper end of the first connecting rod 18 is located in the receiving groove 20 and moves in the receiving groove 20. The outer diameter of the first connecting rod 18 is adapted to the inner diameter of the receiving groove 20. A support spring 21 is arranged between the bottom of the receiving groove 20 and the top of the first connecting rod 18.
[0040] The bottom end of the outer sleeve 1 is provided with a fixed handle 22 and a movable handle 23. The fixed handle 22 is fixedly connected to the outer sleeve 1. A rotating shaft 24 rotatably connected to the inner wall of the outer sleeve 1 is provided on the movable handle 23. One end of the tensioning steel wire rope 14 is connected to the fixed handle 22, and the other end of the tensioning steel wire rope 14 is connected to the rotating shaft 24. The movable handle 23 and the rotating shaft 24 are used to drive the tensioning steel wire rope 14 to drive the test head 5 to move. The maximum rotation angle of the movable handle 23 is 60 degrees.
[0041] In the natural state, both the fixed handle 22 and the movable handle 23 are arranged along the length direction of the outer sleeve 1, and the driving rod 17 is arranged along the length direction of the outer sleeve 1. When it is necessary to move the test head 5, the operator rotates the movable handle 23 in a direction away from the fixed handle 22. When the first clamping chuck 2 and the second clamping chuck 3 clamp both ends of the emergency lighting lamp 4, the test head 5 is located on one side of the emergency lighting lamp 4. At this time, the distance between the test head 5 and the self-check button 6 is relatively close. Therefore, the driving rod 17 only needs to swing within a small range to make the test head 5 press the self-check button 6. In this embodiment, the rotation angle of the movable handle 23 is 10 degrees. At this time, the movable handle 23 drives the rotating shaft 24 to rotate. During the rotation of the rotating shaft 24, one end of the tensioning steel wire rope 14 is wound around the outer wall of the rotating shaft 24, so that the length of the tensioning steel wire rope 14 on the side close to the emergency lighting lamp 4 becomes shorter, and the upper end of the tensioning steel wire rope 14 moves in the direction close to the emergency lighting lamp 4. During the movement of the tensioning steel wire rope 14, it drives the driving rod 17 to swing in the direction close to the emergency lighting lamp 4, and the driving rod 17 drives the test head 5 to move until the test head 5 presses the self-check button 6.
[0042] During the rotation of the rotating shaft 24, a pulling force will be applied to one end of the tensioning steel wire rope 14, making the overall movable length of the tensioning steel wire rope 14 shorter. At this time, the upper end of the tensioning steel wire rope 14 will apply a downward pressure to the movable shaft 16. At this time, the movable shaft 16 moves downward, causing the top end of the first connecting rod 18 to move into the receiving groove 20. At this time, the support spring 21 is compressed, making the distance between the limit block 15 and the movable shaft 16 flexibly adjustable. After the operator releases the movable handle 23, the support spring 21 automatically resets under the action of its own elastic force, and the tensioning steel wire rope 14 also automatically resets under the elastic force of the support spring 21.
[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
