Description

Technical Field

[0002] The optical cable junction box is a connection device installed outdoors, which at least includes a box, a wiring unit, a fusion unit, a storage unit and a protection unit. The various units in the optical cable junction box are composed of various parts and components. In order to fix these parts, many panels and fixings are added to the box. Therefore, the waterproof and moisture-proof test of the optical cable junction box is the top priority of its quality inspection.

[0003] The existing waterproof and moisture-proof test of the optical cable junction box is usually carried out through a salt spray test machine. Through the salt spray test, the panels, waterproof materials, fixings, and electronic components of the optical cable junction box are tested to ensure that the waterproof and moisture-proof performance of the optical cable junction box meets the standards. However, the storage structure of the existing salt spray test machine is often a storage bar with two gear bars. The object to be tested is placed on the storage bar and blocked by the gear bars. This storage structure can often only carry a small number of objects to be tested, which is very inconvenient for the optical cable junction box that needs to test a large number of objects at the same time. In addition, since there are many plate-like parts in the optical cable junction box, the storage structure of the existing salt spray test machine is not very convenient. Summary of the invention

[0020] 2. The drums rotate relative to each other, and the end drum is fixed with a shaft, which is rotatably connected to the test box.

DETAILED DESCRIPTION

[0032] Combined with Figure 1-Figure 5 The experimental device for testing an optical cable junction box comprises an experimental box 10 and a control box 19, a control panel 20 is installed on the control box 19, a pair of mounting seats 18 are fixed on the experimental box 10, a cover body 16 is rotatably installed between the two mounting seats 18, a handle 17 is fixed on the cover body 16, a salt spray space 47 is opened in the experimental box 10, a spray structure 27 is fixedly installed at the bottom of the salt spray space 47, the spray structure 27 is used to generate salt spray to perform salt spray corrosion test on the items in the salt spray space 47, the spray amount can be manually adjusted, and at least one fog collector 26 is fixed on the side wall of the salt spray space 47;

[0033] The cover 16 and the experimental box 10 are sealed with water, specifically, a fixing frame 14 is fixed on the experimental box 10, a water tank 25 is fixed on the fixing frame 14, the water tank 25 is used to hold water, and when the cover 16 is inserted into the water tank 25, the water in the water tank 25 and the cover 16 are sealed;

[0034] Two groups of storage mechanisms 60 are symmetrically arranged around the spray structure 27, each of the storage mechanisms 60 is composed of a symmetrically arranged storage strip structure 50, and the storage strip structure 50 is composed of a plurality of rotating drums 28, the rotating drum 28 closest to the side wall of the salt spray space 47 is fixed to the side wall of the salt spray space 47, and the remaining rotating drums 28 are rotatably connected to each other;

[0035] A locking structure is provided between each of the rotating drums 28, and each of the rotating drums 28 can be relatively fixed by the locking structure. When unlocked, each of the rotating drums 28 is still in a rotationally connected state. A storage assembly is installed on each of the rotating drums 28, and the storage assembly includes a slide rail 42 fixed to the rotating drum 28, and a plurality of storage rods 43 are slidably installed on the slide rail 42. Each of the storage rods 43 is used to place items to be tested. When dealing with plate-like parts or small parts of different sizes in the optical cable junction box, two of the storage rods 43 are used as a group to set up parts. Since the storage rods 43 are slidably installed on the slide rail 42, the spacing between the storage rods 43 is adjustable, and can be freely adjusted according to the size of the parts, and the adaptability is very high. Moreover, due to the setting of each of the storage rods 43, a large number of parts can be placed at one time for testing;

[0036] The rotating drum 28 at the end is fixed with a rotating shaft 24, and the rotating shaft 24 is rotatably connected to the experimental box 10. Sealing measures should be taken between the rotating shaft 24 and the experimental box 10 to prevent salt mist from overflowing. The rotating drum 28 at the end is driven to rotate by rotating the rotating shaft 24. Through the locking structure, the rotating drum 28 at the end can drive other rotating drums 28 to rotate together, thereby adjusting the angle of the storage assembly on the rotating drum 28 so that the parts on the storage assembly can be tilted to achieve the best salt mist contact effect. The number of the rotating drums 28 that rotate together can be achieved by adjusting the locking structure on each of the rotating drums 28. The several rotating drums 28 that are relatively locked with the rotating drums 28 fixed to the side wall of the salt mist space 47 cannot rotate, and the remaining rotating drums 28 will rotate together.

[0037] Further, a baffle 40 is provided on one side of the slide rail 42, and a through slot 41 is provided on the baffle 40, and each of the placement rods 43 passes through the through slot 41. Guide slots 39 are symmetrically provided on both sides of the baffle 40, and a guide bar 37 is provided in sliding connection with and through the guide slot 39, and the guide bar 37 is fixed to the slide rail 42 so that the baffle 40 can slide relative to the slide rail 42, and a threaded hole is provided on one side of the guide slot 39, and a screw 38 is threadedly connected to the threaded hole By rotating the screw 38, the screw 38 can lock the guide bar 37 under the action of the threaded connection to achieve the positioning of the baffle 40 on the guide bar 37. The baffle 40 is used to support the parts on the storage rod 43. Even if the storage assembly is tilted, the baffle 40 can still support the parts to prevent the parts from falling. In addition, by adjusting the position of the baffle 40, the position of the parts on the storage rod 43 can also be adjusted, so that the parts can obtain the best salt spray test effect.

[0038] Furthermore, in order to cope with columnar parts or parts with strong rolling properties, the two storage strip structures 50 in the storage mechanism 60 are symmetrically arranged, and after the rotating drums 28 in the two groups of the storage strip structures 50 are rotated in directions close to each other, the storage rods 43 in one group of the storage strip structures 50 can be staggered with the storage rods 43 in the other group of the storage strip structures 50 to achieve support, thereby placing such parts.

[0039] Similarly, the staggered placement rods 43 can also be adjusted according to user needs to accommodate parts of different sizes, and the number of the rotating drums 28 to be rotated to stagger the placement rods 43 can also be adjusted according to user needs.

[0040] It should be particularly noted that the guide strips 37 in the two symmetrically arranged storage strip structures 50 are also staggered after rotation, and no collision occurs.

[0041] The locking structure comprises a fixing seat 30 fixed on one of the rotating cylinders 28 and a socket 36 fixed on another adjacent rotating cylinder 28, a spring slot 32 is provided in the fixing seat 30, a spring 31 is fixed to the side wall of the spring slot 32, a latch 34 slidably connected to the spring slot 32 is fixed at one end of the spring 31, the end of the latch 34 is inserted into a socket 44 provided in the socket 36, a paddle 33 is fixed on the latch 34, and the paddle 33 can be manually pushed to push the latch 34 out of the socket 44, and the spring 31 is compressed to achieve unlocking;

[0042] Furthermore, since the rotating drums 28 can rotate relative to each other, in order to prevent the pin 34 from popping out, a second blocking piece 35 is fixed at the position of the socket 36 on the rotating drum 28. After the pin 34 is separated from the socket 36, it will resist the second blocking piece 35 until the pin 34 is aligned with the socket 44. Under the resetting action of the spring 31, the pin 34 will be reinserted into the socket 44 to achieve locking.

[0043] A connecting strip 48 is slidably inserted at the end of the rotating shaft 24 (the connecting strip 48 can only slide relative to the rotating shaft 24, but cannot rotate, but cannot be separated from the rotating shaft 24), and a gear 23 is fixed to the end of the connecting strip 48, and the gear 23 is meshed with the rack 22. Through the meshing of the gear 23 and the rack 22, when the rack 22 is stationary, the gear 23 cannot rotate either, thereby realizing the locking of each rotating drum 28 after rotation, and manually pulling the connecting strip 48 out of the rotating shaft 24 so that the gear 23 is separated from the meshing of the rack 22. At this time, the gear 23 can be manually rotated, which can drive each rotating drum 28 fixed to the rotating shaft 24 to rotate, thereby realizing angle adjustment;

[0044] Furthermore, the applicant hopes to achieve the swing of the rotating drum 28. To this end, the rack 22 is fixed on a slide 49, and the slide 49 is slidably installed on a sliding seat 21. The sliding seat 21 is fixed to the experimental box 10. One end of the rack 22 is fixed to a piston rod 13. The piston rod 13 is controlled to be retracted and extended by an electric telescopic rod 12. The electric telescopic rod 12 is fixed to a base 11, and the base 11 is fixed to the experimental box 10. The electric telescopic rod 12 controls the piston rod 13 to be repeatedly retracted and extended to drive the rack 22 to move repeatedly, thereby driving each of the gears 23 to rotate repeatedly, thereby driving each of the rotating drums 28 fixed to the gears 23 to repeatedly swing, thereby achieving repeated swinging of the parts on the rotating drum 28, so that the parts on the rotating drum 28 can fully contact the salt spray.

[0045] In addition, the rotational connection between the rotating drums 28 is achieved through the following structure: a rotation groove 45 is opened at one end of one of the rotating drums 28, and a rotating head 46 is fixed on the adjacent rotating drum 28, and the rotating head 46 is rotatably arranged in the rotation groove 45.

[0046] In addition, the applicant would like to specifically point out that a control terminal is integrated in the control box 19, and the operation of various electronic components in the present application is controlled by the control terminal, including controlling the repeated extension and retraction of the electric telescopic rod 12, as well as the air pump, water pump, etc. in the present application which are not shown in the figure but are essential electronic components for the operation of the salt spray tester.

[0047] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
