[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0043] Please see Figures 1-12 As an embodiment of the present utility model, the packaging fixture for the steel tube of the optical communication wavelength division multiplexer includes a base 1 and a push channel 107 opened at the bottom of the base 1 along the length direction of the base 1.

[0044] The pusher 107 passes through the base 1, and a push rod 105 is slidably disposed in the pusher 107. The push rod 105 is a stepped rod, and the pusher 107 is a stepped hole.

[0045] A compression spring 106 is fitted on the push rod 105. One end of the compression spring 106 abuts against the step on the push rod 105, and the other end abuts against the step on the push track 107.

[0046] The base 1 has an integrally formed stop wall 101, and a stop block 102 is fixedly installed at one end of the push rod 105. The stop wall 101 and the stop block 102 are respectively provided with a fixed slot 103 and a movable slot 104. The fixed slot 103 and the movable slot 104 cooperate to clamp the wavelength division multiplexer steel pipe fitting 2.

[0047] In this embodiment, when assembling the fixture, firstly, a compression spring 106 is threaded through the push rod 105, and then the push rod 105 with the compression spring 106 threaded through it is pushed into the push channel 107 from the large-diameter end of the push channel 107. When one end of the compression spring 106 contacts the step of the push channel 107, the push rod 105 is pushed further, and the compression spring 106 is continuously compressed until one end of the push rod 105 extends out from the small-diameter end of the push channel 107. Finally, the stop block 102 is fixedly installed on the small-diameter end of the push rod 105. At this time, because the small-diameter end of the push rod 105 is limited by the stop block 102, the small-diameter end of the push rod 105 cannot retract into the push channel 107, thereby keeping the compression spring 106 in a compressed state.

[0048] The assembled fixture can be pushed by external force (including but not limited to human force) to push the large-diameter end of the push rod 105, further compressing the compression spring 106, thereby moving the stop block 102 away from the stop wall 101. Then, the wavelength division multiplexer steel pipe fitting 2 to be packaged is placed between the stop wall 101 and the stop block 102, and both ends of the wavelength division multiplexer steel pipe fitting 2 are aligned with the fixed bayonet 103 and the movable bayonet 104, respectively. Finally, the external force applied to the large-diameter end of the push rod 105 is removed, and the compression spring is used to... The elastic force of 106 drives the push rod 105 to reset, which in turn drives the stop block 102 to move closer to the stop wall 101. Finally, the movable slot 104 on the stop block 102 cooperates with the fixed slot 103 on the stop wall 101 to elastically fix both ends of the wavelength division multiplexer steel pipe 2. After the encapsulating adhesive of the wavelength division multiplexer steel pipe 2 is completely dry and firmly bonded, the large diameter end of the push rod 105 is pushed to remove the fully encapsulated wavelength division multiplexer steel pipe 2.

[0049] The structural improvements to this fixture have the following key advantages:

[0050] 1. The product packaging is applicable to various wavelength division multiplexer steel pipe fittings of different diameters and lengths, improving versatility.

[0051] 2. Simple operation, easy placement and removal of wavelength division multiplexer steel pipe fittings 2, high efficiency. After assembling multiple packaging fixtures side by side into an integral structure, and connecting the large diameter ends of each push rod 105 through an integral pusher, multiple wavelength division multiplexer steel pipe fittings 2 can be clamped and placed simultaneously.

[0052] 3. Stable: Compared to placing it directly on a workbench, the steel pipe fitting 2 of the wave division multiplexer is always subjected to elastic clamping force before the glue dries, so it will not loosen and cause poor sealing.

[0053] As a further embodiment of this utility model, the wavelength division multiplexer steel pipe fitting 2 includes a steel pipe body 201 and steel caps 202 detachably installed at both ends of the steel pipe body 201. A rubber plug 203 is fitted onto the steel cap 202. When the rubber plug 203 is sealed to the end of the steel pipe body 201 through the steel cap 202, the rubber plug 203 is clamped between the inner wall of the steel cap 202 and the end of the steel pipe body 201.

[0054] Both the fixed latch 103 and the movable latch 104 are tapered openings, forming a large tapered opening and a small tapered opening on the sides of the stop wall 101 and the block 102, respectively. The large tapered opening formed on one side of the stop wall 101 and the large tapered opening formed on one side of the block 102 are directly opposite each other.

[0055] In this embodiment, it is precisely because the fixed bayonet 103 and the movable bayonet 104 are set to a conical shape that the conical rubber plugs 203 at both ends of the wavelength division multiplexer steel pipe fitting 2 are more easily inserted; and it can accommodate wavelength division multiplexer steel pipe fittings 2 with a wider diameter range.

[0056] As a further embodiment of this utility model, the bottom of the base 1 is also provided with an installation port 108, the installation port 108 is connected to a section of the push track 107, a cover plate 109 is detachably provided on the outside of the installation port 108, and a limit nut 110 is installed on the push rod 105.

[0057] Since the compression spring 106 is already compressed when the small-diameter end of the push rod 105 passes through the small-diameter end of the push track 107, in order to avoid continuously applying external force to the large-diameter end of the push rod 105 during the replacement of the adjustment block 102 (when the block 102 is not fixed to the small-diameter end of the push rod 105), a limiting nut 110 is provided in this solution. After the push rod 105 is inserted into the push track 107, the limiting nut 110 can be installed on the push rod 105 through the mounting port 108. At this time, even if the block 102 is not fixed to the small-diameter end of the push rod 105, the elastic force of the compression spring 106 cannot make the push rod 105 disengage from the push track 107.

[0058] In addition, in order to ensure that the side of the stop block 102 is perpendicular to the base 1, a positioning pin 111 is fixedly provided on the side of the stop block 102 near the stop wall 101, and a positioning hole 112 is provided at the small diameter end of the push rod 105.

[0059] In this embodiment, by the cooperation of the positioning pin 111 and the positioning hole 112, the push rod 105 can be effectively prevented from rotating relative to the stop block 102 after the stop block 102 is installed on the small diameter end of the push rod 105.

[0060] As a further embodiment of this utility model, two clamping members 113 are symmetrically arranged on the base 1. The clamping members 113 are arc-shaped, and the center lines of the two clamping members 113 overlap with the axes of the fixed bayonet 103 and the movable bayonet 104.

[0061] The push rod 105 is connected to the two clamping members 113 through an opening and closing mechanism. The opening and closing mechanism can drive the two clamping members 113 away from each other as the push rod 105 drives the stop block 102 away from the stop wall 101; and keep the two clamping members 113 stationary as the stop block 102 approaches the stop wall 101.

[0062] In this embodiment, since the specifications of the wavelength division multiplexer steel pipe fitting 2 are not entirely the same, the two ends of the wavelength division multiplexer steel pipe fitting 2 are not necessarily within the range of the large conical opening (including left and right and up and down). Theoretically speaking, for wavelength division multiplexer steel pipe fittings 2 with larger and smaller diameters, the rubber plugs 203 at both ends of the wavelength division multiplexer steel pipe fitting 2 cannot be embedded in them by the large conical opening on the stop block 102 and the large conical opening on the stop wall 101 alone. However, the clamping member 113 in this application can clamp wavelength division multiplexer steel pipe fittings 2 of different specifications and models, and after clamping, the axis of the wavelength division multiplexer steel pipe fitting 2 is kept to overlap with the center line of the two clamping members 113, thereby ensuring that the axis of the wavelength division multiplexer steel pipe fitting 2 overlaps with the axis of the large conical opening.

[0063] As a further embodiment of this utility model, the opening and closing mechanism includes a connecting member 114 fixedly connected to the clamping member 113, a movable seat 115 fixedly connected to the connecting member 114, a mounting seat 119 elastically connected to the movable seat 115, a fixed triangular block 117 fixedly installed on the movable seat 115, and a single-pass extrusion structure that respectively cooperates with the push rod 105 and the fixed triangular block 117.

[0064] The mounting bracket 119 is fixedly mounted on the base 1.

[0065] In this embodiment, when an external force pushes the push rod 105 and causes the stop block 102 to move away from the stop wall 101, the push rod 105 drives the single-pass extrusion structure to cooperate with the fixed triangular block 117, causing the clamping members 113 on both sides to move away from each other, so that the wavelength division multiplexer steel tube 2 to be packaged falls between the two clamping members 113; after the single-pass extrusion structure passes the fixed triangular block 117, the two clamping members 113 move closer to each other, thereby clamping the wavelength division multiplexer steel tube 2 between the two clamping members 113 and ensuring that the axis of the wavelength division multiplexer steel tube 2 overlaps with the axis of the large conical opening; after the external force applied to the end of the push rod 105 is removed, the spring force of the compression spring 106 drives the stop block 102 to move closer to the stop wall 101. During this process, the single-pass extrusion structure does not cause the two clamping members 113 to move away from each other, thereby keeping the wavelength division multiplexer steel tube 2 clamped.

[0066] As a further embodiment of this utility model, a guide rod 116 is fixedly installed on the mounting base 119, and a spring 118 is sleeved on the guide rod 116. The movable seat 115 is slidably disposed on the guide rod 116, and one end of the spring 118 abuts against the movable seat 115, and the other end abuts against the mounting base 119.

[0067] In this embodiment, under the action of spring 118, the movable seat 115 always tends to move towards the center of the base 1. When the single-pass extrusion structure and the fixed triangular block 117 act in the same direction, the fixed triangular block 117 drives the movable seat 115 to slide along the guide rod 116 away from the center of the base 1 and compresses the spring 118. Once the single-pass extrusion structure passes the fixed triangular block 117, under the elastic force of spring 118, the movable seat 115 will quickly return to its original position and move towards the center of the base 1. During this process, the movable seat 115 drives the clamping members 113 on both sides to move closer to each other through the connecting member 114, and finally clamps the wavelength division multiplexer steel pipe 2 located between the two clamping members 113.

[0068] As a further embodiment of this utility model, the base 1 is provided with a through groove 129, which is connected to the pusher 107. The pusher 105 is provided with an installation channel 120, in which a slider 121 is adjustablely and fixedly installed. The slider 121 passes through the through groove 129 and connects to the single-pass extrusion structure.

[0069] In this embodiment, the through groove 129 allows a section of push rod 105 located in the push track 107 to cooperate with the single-pass extrusion structure; in addition, the slider 121 can also prevent the push rod 105 from rotating in the push track 107.

[0070] As a further embodiment of this utility model, the single-pass extrusion structure includes a push plate 122 that is slidably disposed on the base 1 and fixedly connected to the slider 121, and a hinge seat 125 is fixedly installed on the push plate 122.

[0071] A swaying triangular block 127 is hinged to the hinge seat 125 via a pivot 126. A spring 128 is also provided between the hinge seat 125 and the swaying triangular block 127. One end of the spring 128 is fixed to the hinge seat 125, and the other end is elastically pressed against the swaying triangular block 127.

[0072] In this embodiment, when the push rod 105 drives the stop block 102 away from the stop wall 101, the push rod 105 drives the push plate 122 to follow away from the stop wall 101 through the slider 121. During this process, the push plate 122 drives the swaying triangle block 127 to move synchronously through the hinge seat 125. After the swaying triangle block 127 interacts with the fixed triangle block 117, as the swaying triangle block 127 continues to move, it will drive the fixed triangle block 117 to give way, thereby causing the movable seat 115 to continuously compress the spring 118 and move away from the center of the base 1. Once the swaying triangle block 127 passes the fixed triangle block 117, it will quickly drive the movable seat 115 to reset under the elastic force of the spring 118.

[0073] Furthermore, during the return stroke of the yaw block 127, due to the interaction between the flat surface of the yaw block 127 and the flat surface of the fixed block 117, the force of the yaw block 127 is perpendicular to the length direction of the guide rod 116. Therefore, the fixed block 117 will not give way. Thus, the yaw block 127 can only pass over the fixed block 117 by deflecting the spring 128 to bend.

[0074] As a further embodiment of this utility model, the push plate 122 is provided with a sliding hole, which is slidably engaged with the track rod 123, and the track rod 123 is fixedly installed on the base 1 by a fixing seat 124.

[0075] In this embodiment, by means of the sliding engagement between the sliding hole and the track rod 123, the push plate 122 can only slide on the base 1 along the length direction of the mounting groove 120 and the through groove 129.

[0076] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
