Description

Technical Field

[0001] The utility model relates to the technical field of lighting testing, in particular to a lighting testing stand. Background Art

[0002] Currently, single-lamp test fixtures are common. With new national standards for linear beam fire detectors' resistance to ambient light, new lamp test fixtures are essential for conducting ambient light interference tests to ensure the accuracy and reliability of test results. Traditional testing methods and equipment have exposed significant shortcomings when facing these new standards.

[0003] First, traditional single-lamp test fixtures are often designed as a fixed, integrated structure, which limits their flexibility. If the test environment or location needs to be changed, the entire test fixture is difficult to disassemble and move, making transportation more difficult and increasing the risk of damage during transport. Furthermore, if the test fixture is damaged, repair or replacement becomes complex, sometimes even requiring the construction of a completely new test fixture, which is not only time-consuming but also incurs additional costs.

[0004] Secondly, when testing two different lamps simultaneously, using a single-lamp test rack results in inefficient space utilization. Two separate single-lamp test racks not only take up valuable lab space but also complicate the layout. The actual operation may be limited by the size and layout of the site, thus affecting the smooth progress of the test.

[0005] In view of the above problems, there is an urgent need to design a new lamp test stand that is easy to install and disassemble and is safer in transportation and storage. Utility Model Content

[0006] The purpose of the utility model is to provide a lighting test stand, which is easy to install and disassemble and has safety advantages in transportation and storage.

[0007] In order to solve the above technical problems, an embodiment of the present utility model provides a lighting test stand, comprising several segmented frames connected in sequence, adjacent segmented frames being connected by merging parts, the segmented frames comprising a support base, a main frame and a support arm, the support base and the support arm being respectively installed at the top and bottom of the main frame, the top of the main frame providing an installation station for a type of light source, and the support arm providing an installation station for a type of light source.

[0008] Furthermore, the top of the main frame and the support arm are both rail profiles, and the support arm is slidably hinged to the top of the main frame through a connecting piece.

[0009] Furthermore, the connecting member includes a slider and a hinge block, the slider and the hinge block are connected through end bearings, the slider is slidably connected in the track at the top of the main frame, and the hinge block is fixedly installed in the middle of the track of the support arm.

[0010] Furthermore, the merging piece is installed on the vertical beam of the main frame, and the merging piece includes an assembly block embedded in the vertical beam and a restraining belt connected to the assembly block. When the merging piece connects adjacent segmented frames, the tracks on the tops of adjacent main frames are connected to each other.

[0011] Furthermore, the support seat includes a seat body, a hinge shaft and a stop block. The seat body has a triangular frame structure. The top of the seat body is rotatably connected to the vertical beam of the main frame through the hinge shaft. A limiting connecting block is provided between the support seat and the main frame. A stop block is provided on the seat body for supporting the limiting connecting block.

[0012] Furthermore, a roller is installed on the base.

[0013] Beneficial effects: The design of the lighting test stand provided by the utility model overcomes the deficiencies of traditional single-lamp test stands in terms of flexibility, portability, storage space utilization efficiency, and maintenance convenience.

[0014] The lighting test stand proposed in this utility model features a segmented frame design, allowing each section to be independently installed and removed, greatly improving the ease of transport and installation. This new design allows for partial replacement of damaged parts, reducing the need for complete rework and saving repair time and costs. By integrating multiple lighting fixtures into a single structure, the new test stand reduces required space and simplifies test setup. The segmented frame design can be stacked when not in use, significantly saving storage space.

[0015] In summary, the lighting test stand proposed in the present invention effectively solves many problems existing in traditional test stands with its unique segmented design, flexible connection mechanism and easily adjustable light source installation position, providing strong support for improving test efficiency and quality.

[0024] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that many technical details are provided in various embodiments of the present invention to facilitate a better understanding of the present application. However, even without these technical details and the various variations and modifications based on the following embodiments, the technical solutions claimed in the claims of this application can be achieved.

[0025] like Figures 1-6 As shown, a lighting test stand includes several segmented frames 1 connected in sequence. Adjacent segmented frames 1 are connected by merging pieces 7. The segmented frames 1 include a support base 2, a main frame 4 and a support arm 6. The support base 2 and the support arm 6 are respectively installed on the top and bottom of the main frame 4. The top of the main frame 4 provides an installation position for a type I light source, and the support arm 6 provides an installation position for a type II light source.

[0026] The utility model adopts a segmented design, which not only makes the test frame easy to install and disassemble, but also greatly improves the safety and convenience of transportation and storage; at the same time, the integration of multiple lamp installation stations in a segmented frame 1 reduces the required space, simplifies the test layout, meets the needs of multiple light source tests, increases test flexibility, and improves work efficiency.

[0027] The top of the main frame 4 and the support arm 6 are both rail profiles, and the support arm 6 is slidably hinged to the top of the main frame 4 via a connector 5. This design provides a flexible position adjustment structure for the support arm 6, allowing the support arm 6 to slide freely along the track at the top of the main frame 4 as needed, thereby facilitating flexible adjustment of the light source spacing and ensuring that the light source position can be quickly and accurately set in different test scenarios, thereby meeting diverse testing needs.

[0028] like Figure 5 As shown, the connector 5 includes a slider 51 and a hinge block 52. The slider 51 and the hinge block 52 are connected by end bearings. The slider 51 is slidably connected to the track at the top of the main frame 4, and the hinge block 52 is fixedly installed in the middle of the track of the support arm 6. The design of the connector 5 not only enables the support arm 6 to slide within the track at the top of the main frame 4, thereby achieving flexible adjustment of the light source station, but the end bearing connection between the slider 51 and the hinge block 52 allows the support arm 6 to be rotated and stored, reducing the occupied space and facilitating management and maintenance.

[0029] like Figure 2 and Figure 6 As shown, the merging member 7 is mounted on the vertical beam of the main frame 4. The merging member 7 includes an assembly block 71 embedded in the vertical beam and a tie band 72 connected to the assembly block 71. When the merging member 7 connects adjacent segmented frames 1, the tracks at the tops of adjacent main frames 4 are interconnected. The merging member 7 not only efficiently and quickly connects the segmented frames 1, but also ensures that the tracks at the tops of adjacent main frames 4 are interconnected. This design not only simplifies the connection process between frames, but also requires high assembly precision for adjacent segmented frames 1, thereby providing a reliable platform for the installation and adjustment of light sources.

[0030] like Figure 3 and Figure 4 As shown, the support base 2 includes a base body 21, a hinge shaft and a stopper 22. The base body 21 is a triangular frame structure. The top of the base body 21 is rotatably connected to the vertical beam of the main frame 4 through the hinge shaft. A limit connection block 3 is provided between the support base 2 and the main frame 4. A stopper 22 is provided on the base body 21 for supporting the limit connection block 3. The design of the limit connection block 3 has an important influence on the relative position relationship between the support base 2 and the main frame 4. It can lock the two states between the two: one is that when working, the support base 2 forms a stable angle with the main frame 4 to ensure the stable placement of the test stand; the other is that when idle, the support base 2 can rotate and fit with the main frame 4, facilitating the stacking and storage of the segmented frame 1 and saving storage space. Through the action of the limit connection block 3, the test stand can maintain good stability during use and can be easily and quickly folded up when not in use, thereby improving space utilization efficiency.

[0031] In particular, rollers are installed on the base 21. The rollers enable each segmented frame 1 to move independently, greatly enhancing the overall flexibility of the multi-segmented frame 1. This allows the segmented frame 1 to be easily moved during the assembly of the entire test frame, thereby quickly completing the construction of the test frame. After the test is completed, the test frame can also be easily disassembled and moved to a storage location using the rollers, or the test frame can be conveniently rearranged when the test environment needs to be adjusted. The use of rollers not only improves work efficiency, but also reduces the risk of damage to the equipment during transportation.

[0032] When the utility model is used, the appropriate number of segmented frames 1 are selected for connection according to the light source test requirements. When the specified number of segmented frames 1 are taken out from the warehouse, the posture of the segmented frames 1 is as follows: Figure 3 As shown, such a state is very convenient for storing a large number of segmented frames 1 side by side, saving storage space.

[0033] When taking out the segmented frame 1, it is more convenient to use the roller to move the segmented frame 1. The first step in assembling multiple segmented frames 1 into a light test stand is to move the segmented frames 1 from the Figure 3 The posture is adjusted to Figure 2 posture to ensure that the opposing segmented frame 1 can be placed stably.

[0034] Specifically, the above-mentioned posture change process requires moving the limit connecting block 3 upward until the limit connecting block 3 is separated from the support seat 2, and then rotating the support seat 2 so that the support seat 2 originally at the main frame 4 becomes perpendicular to the main frame 4, and then opening the limit connecting block 3 so that it falls onto the stop block 22 again, completing the posture locking of the main frame 4 and the support seat 2.

[0035] After adjusting the posture of the vertical segmented frames 1, all the segmented frames 1 are arranged in sequence, and the main frames 4 of adjacent segmented frames 1 are aligned. Then, the binding belt of the merging piece 7 is wrapped around the vertical beams of the adjacent main frames 4 and tied. After the adjacent segmented frames 1 are connected using the merging piece 7, the support arm 6 on the main frame 4 is slid. If the connecting piece 5 can move smoothly between the two main frames 4, the adjacent segmented frames 1 are aligned. Otherwise, the connection effect of the merging piece 7 needs to be fine-tuned.

[0036] After all the segmented frames 1 are connected in sequence, the adjacent arms 6 are adjusted to the light source test distance using the connecting piece 5 , and the posture of the arms 6 is fixed using the locking piece.

[0037] Finally, the first type of light source is installed on the top of the main frame 4, and the second type of light source is installed on the end of the support arm 6.

[0038] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
