Description

Technical Field

[0001] The utility model relates to the technical field of lamp testing tooling, in particular to a lamp testing frame with adjustable spacing. Background Art

[0002] Lamps are a general term for lighting tools, which are divided into chandeliers, table lamps, wall lamps, floor lamps, etc. They refer to appliances that can transmit light, distribute and change the light distribution of light sources. In addition to the light source, they include all parts required to fix and protect the light source, as well as the wiring accessories necessary for connection to the power supply. During the production process of lamps, the lamps need to be powered on and tested to ensure that they can operate normally. During the testing process, lamp test stands are needed to place the lamps so that staff can test the lamps and ensure the stability of the lamps during the test.

[0003] Prior art, such as the utility model patent with publication number CN204903590U, discloses a lamp aging test stand. The patent comprises a first support rod assembly, a second support rod assembly, and a retractable lamp hanging rod assembly mounted between the first and second support rod assemblies. The retractable lamp hanging rod assembly includes an outer tube and an inner tube. The left end of the outer tube is fixed to the first support rod assembly, and the right end slides over the left end of the inner tube, which is fixed to the right end of the second support rod assembly. This lamp aging test stand can expand or contract in size to meet user needs and address the problem that lamp hanging rods are generally fixed in length, resulting in a fixed number of lamps that can be hung on them. When testing a large number of lamps, batch testing is required, which is very inconvenient. When testing a small number of lamps, especially in a small test room, the lamp hanging rod cannot be shortened, resulting in the lamp aging test stand taking up a lot of space and making it difficult for people to move around the room.

[0004] The inventor found in his daily work that in the process of testing lamps with the help of a lamp test stand, there are existing lamp test stands such as the above-mentioned ones that use bolts as fixing parts on the adjustment structure. When adjusting, the bolts need to be removed, and then the brackets for support are pulled to both sides. When the brackets are adjusted to the appropriate position, the bolts are installed into the reserved threaded holes. When adjusting the brackets, there are detection lamps on the brackets, and the staff need to take down the lamps before they can perform the adjustment operation. Because the bracket adjustment operation steps are relatively large and it is difficult to adjust during use, the adjustment operation of the bracket is inconvenient. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that when there is an adjustment bracket, there is a test lamp on the bracket, and the staff needs to take the lamp down before adjusting the bracket. Since the bracket adjustment operation steps are numerous and it is difficult to adjust during use, the adjustment operation of the bracket is inconvenient. A lamp test stand with adjustable spacing is proposed.

[0006] The cam is secured to the left and right sides of the frame, and the cam is secured to the left and right sides of the frame, and the cam is secured to the left and right sides of the frame.

[0007] Preferably, the threaded rod is rotatably connected to the inner wall of the limit frame, and there are three threaded rods, which are arranged vertically with respect to the left bracket. The threaded rod can cooperate with the threaded sleeve to pull or push the guide frame when being driven, so as to cooperate with the guide frame to adjust the inner support rod.

[0008] Preferably, the guide frame is sleeved with the surface of the threaded rod, and the positioning frame is rotatably connected to the surface of the threaded shaft. The positioning frame can limit the maximum movement distance of the threaded rod to ensure that the position of the thread is within the inner support rod.

[0009] Preferably, a semicircular groove is provided on the outer arc surface of the transmission wheel, the pull rope is arranged in a loop, the raised portion on the pull rope surface is matched with the inner wall of the semicircular groove, and the cooperation between the pull rope and the transmission wheel can synchronously drive the upper and lower threaded rods to rotate.

[0010] Preferably, a restraining assembly is provided on the side surface of the left bracket, and the restraining assembly includes an assembly plate, which is installed on the side surface of the left bracket, and a threaded hole is opened on the surface of the assembly plate, and the assembly plate is threadedly connected to a fixing bolt on the inner wall of the threaded hole, and a first cover plate is installed on the surface of the threaded rod, and an arc-shaped buckle plate is fixedly connected to the side surface of the first cover plate, and a second cover plate is installed on the surface of the threaded rod, and a side baffle is fixedly connected to the side surface of the second cover plate, and the position of the first cover plate and the second cover plate can be restricted by the cooperation of the assembly plate and the fixing bolt.

[0011] Preferably, the assembly plate is socketed with the surface of the threaded rod, the first cover plate is socketed with the surface of the fixing bolt, the first cover plate is in contact with the surface of the transmission wheel, and the arc-shaped cover plate is in contact with the raised portion of the pull rope. The position of the pull rope can be constrained by using the arc-shaped cover plate to ensure that the raised portion of the pull rope is close to the transmission wheel.

[0012] Preferably, the second cover plate is socketed with the surface of the fixing bolt, the first cover plate is in contact with the surface of the transmission wheel, the number of the side baffles is two, and the two side baffles are symmetrically arranged front to back with respect to the second cover plate, and the side baffles are in contact with the raised portion of the pull rope. The position of the pull rope can be constrained from both sides by the side baffles, thereby ensuring that the raised portion of the pull rope will fit into the transmission wheel during the rotation process.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] The utility model discloses a device for testing a lamp by providing an adjusting component and a binding component. When the lamp is tested, the lamp is placed on the cross bar composed of the outer support rod and the inner support rod. After the lamp is placed, the operator can power on the lamp to test the lamp. When the spacing of the test frame needs to be adjusted, the pull rope is pulled clockwise. The pull rope rotates under the guidance of the arc-shaped buckle plate and the side baffle. At the same time, the raised portion of the pull rope engages with the semicircular grooves on all the transmission wheels to drive the transmission wheel. During the rotation of the transmission wheel, the threaded rod drives the threaded rod, and the threaded rod rotates and engages with the threaded sleeve. Under the action of the threaded rod, the threaded sleeve drives the guide frame to move. The guide frame is forced to push the inner support rod, and the inner support rod pushes the right bracket outward, and then the adjustment operation of the test frame can be realized. By providing the adjusting component and the binding component, it is convenient for the user to adjust the spacing of the test frame, thereby reducing the problem of more operating steps and interference with the test lamp when bolts are used for fixing, and further improving the convenience of the test frame adjustment operation.
