Description

Technical Field

[0001] The utility model relates to the technical field of wavelength conversion devices, and particularly relates to a test rack for a wavelength conversion device. Background Art

[0002] Wavelength conversion is a necessary means to increase the flexibility of optical switching networks and reduce blocking, and there are also many design schemes for optical network wavelength conversion nodes.

[0003] During the use of a wavelength converter, it needs to be installed and fixed in cooperation with a test rack. The specific installation and fixing process is to place the wavelength converter on the mounting rack and fix it by extrusion through a limiting structure;

[0004] However, during the process of placing the wavelength converter on the test rack and taking it off the test rack, due to the sliding friction between the wavelength converter and the test rack, the wear on the wavelength converter and the test rack is relatively large, and the frictional resistance between the wavelength converter and the test rack is increased, resulting in inconvenient installation and disassembly. Summary of the Utility Model

[0005] Aiming at the above-mentioned disadvantages of the prior art, the utility model provides a test rack for a wavelength conversion device, which can effectively solve the problems raised in the background art.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0007] The utility model provides a test rack for a wavelength conversion device, including a mounting base and a mounting cavity opened at the top of the mounting base. An activity cavity is arranged inside the mounting base. The auxiliary assembly includes several rotating rollers arranged inside the mounting base and capable of extending into the mounting cavity. All the rotating rollers are rotatably arranged. The extrusion and fixing assembly includes two parallelly distributed extrusion plates arranged inside the mounting base and capable of extending into the mounting cavity. When the several rotating rollers descend in height, the two extrusion plates linearly move towards each other.

[0008] Furthermore, square openings for the telescopic sliding of the extrusion plates are respectively formed in the two opposite inner cavity walls of the mounting cavity and penetrate through the activity cavity. A plurality of strip-shaped openings for the telescopic sliding of the several rotating rollers are formed in the bottom of the mounting cavity and penetrate through the mounting activity cavity.

[0009] Furthermore, two parallelly distributed support frames are vertically and fixedly installed at the bottom of the mounting base. A crank is rotatably installed at the bottom of the mounting base. A limiting ring is sleeved at the top of the crank and is rotatably installed on the mounting base in a limiting manner.

[0010] Furthermore, a lifting plate that moves up and down is arranged in the movable cavity. A plurality of mounting blocks arranged in parallel in pairs are vertically and fixedly installed at the top end of the lifting plate, and both ends of a plurality of the rotating rollers are rotatably installed on the corresponding mounting blocks.

[0011] Furthermore, the top end of the crank extends into the movable cavity and is provided with a threaded head. A threaded ring is threadedly sleeved on the threaded head. Two L-shaped fixing blocks are installed between the outer ring wall of the threaded ring and the lifting plate, and a gear is fixedly sleeved on the outer ring wall of the threaded ring.

[0012] Furthermore, two racks are meshingly installed on the outer ring wall of the gear, and the two ends of the two racks away from each other are respectively perpendicularly and fixedly connected to the corresponding pressing plates.

[0013] The technical solution provided by the present utility model has the following beneficial effects compared with the known prior art:

[0014] 1. A plurality of rotatable rotating rollers are arranged at the bottom of the installation cavity for placing the wavelength converter. The rotating rollers can facilitate the placement of the wavelength converter at the bottom of the installation cavity and also facilitate the adjustment of the position of the wavelength converter. The rotation of the rotating rollers can reduce the wear degree during the installation and disassembly of the test rack, and also reduce the frictional resistance, having the characteristics of convenient installation and disassembly.

[0015] 2. A plurality of rotating rollers can be telescopically slid to switch the working state. When the rotating rollers rise in height, the pressing plates on both sides of the installation cavity no longer contact the wavelength converter, facilitating the removal and feeding of the wavelength converter. When the rotating rollers descend in height, the pressing plates on both sides of the installation cavity approach and press against both sides of the wavelength converter, facilitating the installation and feeding of the wavelength converter, having the advantages of reducing operation steps and improving the loading and unloading efficiency.

[0026] The present utility model will be further described below with reference to the embodiments.

[0027] Embodiment 1

[0028] Refer to Figures 1-4 , which is the first embodiment of the present utility model, discloses a test stand for a wavelength conversion device, including a mounting base 1 and a mounting cavity 11 opened at the top of the mounting base 1. An active cavity is provided in the mounting base 1. The auxiliary assembly component includes a plurality of rotating rollers 22 provided in the mounting base 1 and capable of extending into the mounting cavity 11. The plurality of rotating rollers 22 are all rotatably provided. The extrusion and fixing component includes two parallelly distributed extrusion plates 31 provided in the mounting base 1 and capable of extending into the mounting cavity 11. While the plurality of rotating rollers 22 descend in height, the two extrusion plates 31 linearly move towards each other.

[0029] Embodiment 2

[0030] Refer to Figures 1-4, which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: on both opposite inner cavity walls of the installation cavity 11, square openings 12 for the telescopic sliding of the extrusion plate 31 are provided through the movable cavity. Through holes for the telescopic sliding of a plurality of rotating rollers 22 are provided at the bottom of the installation cavity 11 through the installation movable cavity. Two parallelly distributed support frames 13 are vertically and fixedly installed on the lower bottom of the installation base 1. A crank 14 is rotatably installed on the lower bottom of the installation base 1. A limit ring 15 which is limitedly rotatably installed on the installation base 1 is sleeved on the top end of the crank 14. A lifting plate 2 which slides up and down is arranged in the movable cavity. A plurality of installation blocks 21 which are arranged in parallel in pairs are vertically and fixedly installed on the top end of the lifting plate 2. Both ends of a plurality of rotating rollers 22 are respectively rotatably installed on the corresponding installation blocks 21. The top end of the crank 14 extends into the movable cavity and is provided with a threaded head 23. A threaded ring 24 is threadedly sleeved on the threaded head 23. Two L-shaped fixing blocks 25 are installed between the outer ring wall of the threaded ring 24 and the lifting plate 2. A gear 26 is fixedly sleeved on the outer ring wall of the threaded ring 24. Two rack bars 33 are meshed and installed on the outer ring wall of the gear 26. L-shaped bent rods 32 are fixedly connected between the far ends of the two rack bars 33 and the corresponding extrusion plates 31 respectively.

[0031] The remaining structures are the same as those in Embodiment 1.

[0032] The working process of the present utility model is as follows:

[0033] During the installation process of the wavelength converter, the wavelength converter is placed at the bottom of the installation cavity 11. At this time, a plurality of rotating rollers 22 extend out from the corresponding strip holes, and the top ends are all located in the installation cavity 11 and contact the lower bottom of the wavelength converter. Through the rotation of the plurality of rotating rollers 22, it is convenient to move the wavelength converter to the center position of the installation cavity 11. At this time, rotate the crank 14 to drive the threaded head 23 to rotate, and then drive the threaded ring 24 to rotate synchronously. However, since the threaded ring 24 is connected to the lifting plate 2 through the L-shaped fixing block 25, and the rotating rollers 22 at the top of the lifting plate 2 are always located in the strip holes, the rotation of the threaded head 23 will drive the threaded ring 24, that is, the lifting plate 2 and a plurality of rotating rollers 22 to descend in height. At this time, the wavelength converter placed on the top of the plurality of rotating rollers 22 will also descend in height synchronously until it contacts the bottom of the installation cavity 11;

[0034] Along with the rotation of the threaded head 23, the gear 26 will also be driven to rotate synchronously, and then drive the two rack bars 33 on both sides to rotate meshingly, so as to respectively pull the corresponding extrusion plates 31 through the L-shaped bent rods 32, extend out from the square openings 12, and squeeze and abut against both sides of the wavelength converter, and simultaneously complete the limit fixation of the wavelength converter;

[0035] During the process of taking out the wavelength converter, rotate the crank 14 in the reverse direction, which drives the threaded head 23 to rotate in the reverse direction, raising the lifting plate 2 and several rotating rollers 22 until the rotating rollers 22 come into contact with the lower bottom of the wavelength converter again. At the same time, the rotation of the threaded head 23 also drives the electric gear 26 to rotate in the reverse direction, which meshes with and drives two L-shaped bent rods 32, driving the corresponding pressing plates 31 to move away from each other, so that the two pressing plates 31 move away from the wavelength converter respectively and retract into the square opening 12. During the process of taking out the wavelength converter, due to the rotation of the rotating rollers 22, it is convenient to take out the wavelength converter.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
