Abstract
Description
Technical Field
[0001] This application relates to the field of optical fiber communication equipment technology, and in particular to a pull-locking structure. Background Technology
[0002] With the progress and development of the times, optical fibers play a vital role in modern communications, medical care, industry and other fields. Fiber optic splitters are key passive devices in fiber optic communication systems. Their core function is to distribute a single optical signal to multiple optical signals in a specific ratio, or conversely, to merge multiple optical signals into a single signal.
[0003] In existing related technologies, fiber optic splitters include fiber optic components and a splitter housing, with the fiber optic components fixedly installed inside the splitter housing. The splitter housing is typically fixed to a support plate using screws. The support plate effectively ensures the stability and portability of the fiber optic splitter, allowing it to be moved to a cabinet for centralized management of multiple fiber optic lines.
[0004] Regarding the aforementioned technologies, although the threaded connection method can ensure the stability of the fiber optic splitter in actual use, disassembly requires tools and screws are easily lost, thus reducing the efficiency of disassembly and assembly. Summary of the Invention
[0005] To improve the efficiency of fiber optic splitter assembly and disassembly, this application provides a pull-locking structure.
[0006] The pull-and-lock structure provided in this application adopts the following technical solution:
[0007] A pull-out snap-fit structure includes a support plate, a limiting strip, a distributor housing, and a pull-out component;
[0008] The limiting strip is provided in a plurality of them, and all of the limiting strips are fixed to the bearing plate. Two blocking protrusions are provided in the middle of the limiting strip. The blocking protrusions are arranged in a right-angled trapezoidal shape, and a positioning groove is formed between the two blocking protrusions.
[0009] The splitter housing has a pull-out groove on its side, and a positioning block is connected to the middle of the pull-out groove. The positioning block is integrally connected to the splitter housing through an elastic sheet. The positioning block is adapted to the positioning groove, and a guide post is fixed to the top of the positioning block. The guide post faces the pull-out component.
[0010] The pull-out component is installed on the side of the splitter housing along the length of the splitter housing. The pull-out component slides and engages with the splitter housing along the length of the splitter housing. A guide adjustment groove is provided in the middle of the pull-out component, and the guide adjustment groove faces the guide post. The pull-out component is pressed against the side wall of the pull-out groove by a transmission spring.
[0011] By adopting the above technical solution, when the splitter housing needs to be installed on the support plate, the splitter housing is first pressed against the limiting strip, and then continuously moved along the length of the limiting strip. Subsequently, the positioning block touches the blocking protrusion and retracts along the trapezoidal slope of the blocking protrusion. After passing the blocking protrusion, the positioning block reaches the positioning groove, where it is fixed, thus securing the splitter housing to the support plate. To remove the splitter housing from the support plate, the pull-out component can be pulled. The transmission spring is continuously compressed, causing the pull-out component to move the guide post along the inner groove of the guide adjustment groove, causing the guide post to retract again and disengage from the positioning groove, thereby gradually disengaging from the limiting strip and achieving disassembly. This effectively improves the efficiency of fiber optic splitter assembly and disassembly.
[0012] Optionally, two limiting protrusions are fixed on the side of the splitter housing, and the two limiting protrusions abut against the bottom of the two blocking protrusions respectively.
[0013] By adopting the above technical solution, when the splitter housing is fixed along the length of the limiting strip, the two limiting protrusions will be respectively set at the bottom of the two blocking protrusions. At this time, the top blocking protrusion will play a role in fixing the splitter housing vertically.
[0014] Optionally, a plurality of first fixing members are fixedly installed on the side of the splitter housing, and a plurality of second fixing members are fixedly installed on the side of the splitter housing. Both the first fixing members and the second fixing members are L-shaped. The pull-out member is disposed on the side of the splitter housing through the first fixing members and the second fixing members. The second fixing member has a snap-fit hole. The side of the pull-out member has a plurality of circular protrusions. The circular protrusions pass through the snap-fit hole, and the pull-out member moves along the length direction of the snap-fit hole.
[0015] By adopting the above technical solution, the pull-out component can be installed on the side of the splitter housing, and the pull-out component is prevented from detaching from the side of the splitter housing in the vertical direction by means of a circular protrusion passing through the snap-fit hole.
[0016] Optionally, the limiting strips are arranged at equal intervals along the length of the bearing plate, and the blocking protrusions are oriented in the same direction.
[0017] By adopting the above technical solution, the splitter housings can be installed side by side on the carrier plate to facilitate subsequent wiring of the fiber optic splitter.
[0018] Optionally, the bottom of the splitter housing is provided with several limiting grooves, and each of the limiting grooves is adapted to the limiting strip.
[0019] By adopting the above technical solution, when the splitter housing is snapped into place along the length of the limiting strip, the limiting groove can pass through the limiting strip, thereby achieving a fixing effect. Furthermore, the splitter housing can be adapted to any limiting strip, allowing the number and position of the splitter housings on the carrier plate to be changed according to actual conditions, thus improving the assembly and disassembly efficiency of the fiber optic splitter.
[0020] Optionally, one end of the pull-out component is provided with a first handle, the first handle having anti-slip texture, and the other end of the pull-out component is provided with a second handle, the second handle being hook-shaped.
[0021] By adopting the above technical solution, when it is necessary to remove the splitter housing from the top of the carrier plate, the first handle or the second handle can be pulled, making the installation and removal of the fiber optic splitter more convenient. In addition, the anti-slip texture of the first handle and the hook-shaped design of the second handle can improve the stability of pulling the first handle or the second handle.
[0022] Optionally, several pulleys are rotatably connected to both sides of the support plate.
[0023] By adopting the above technical solution, the movement of the support plate to the cabinet can be made more convenient by using pulleys.
[0024] Optionally, the support plate has several heat dissipation holes through it.
[0025] By adopting the above technical solution, when multiple fiber optic splitters are installed on the carrier board, the heat generated by most of the fiber optic splitters can be dissipated through the heat dissipation holes. Furthermore, the heat dissipation holes also improve the ease of connecting the fiber optic splitters to the cabinet unit.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. When installing the splitter housing onto the support plate, first press the splitter housing against the limiting strip and continuously move the splitter housing along the length of the limiting strip. Then, the positioning block touches the blocking protrusion and retracts along the trapezoidal slope of the blocking protrusion. After passing the blocking protrusion, the positioning block reaches the positioning groove, where it is fixed, thus securing the splitter housing to the support plate. To remove the splitter housing from the support plate, pull the pull-out component. The transmission spring compresses, causing the pull-out component to move the guide post along the inner groove of the guide adjustment groove, allowing the guide post to retract and disengage from the positioning groove, gradually disengaging from the limiting strip. This achieves disassembly and effectively improves the efficiency of fiber optic splitter assembly and disassembly.
[0028] 2. This design allows the limiting groove to pass through the limiting strip when the splitter housing is snapped into place along the length of the limiting strip, thus achieving a fixing effect. Furthermore, the splitter housing can be adapted to any limiting strip, allowing for changes in the number and position of the splitter housings on the support plate according to actual conditions, thereby improving the assembly and disassembly efficiency of the fiber optic splitter.
[0029] 3. This allows for easier movement of the support plate when moving it to the cabinet via casters. Attached Figure Description

Detailed Implementation
[0040] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.
[0041] This application discloses a pull-and-lock structure. (Refer to...) Figure 1 The pull-and-connect structure includes a bearing plate 1, a limiting strip 2, a distributor housing 3, and a pull-out component 4.
[0042] Reference Figure 2 The support plate 1 has several pulleys 11 rotatably connected to both sides. These pulleys 11 facilitate easier movement of the support plate 1 to the cabinet. The support plate 1 has several ventilation holes 101 arranged in parallel. When a large number of fiber optic splitters are installed on the support plate 1, the heat generated by most of the splitters can be dissipated through the ventilation holes 101. Furthermore, the ventilation holes 101 also improve the ease of cable routing when connecting the fiber optic splitters to the cabinet.
[0043] Reference Figure 3 and Figure 4 Several limiting strips 2 are provided, all fixed to the support plate 1 along its length, with consistent spacing between adjacent limiting strips 2. Two blocking protrusions 21, each a right-angled trapezoid, are located in the middle of the side of each limiting strip 2, with their right-angled ends facing each other. A positioning groove 201 is formed between the two blocking protrusions 21, used to engage the horizontal movement of the splitter housing 3. The blocking protrusions 21 all face the same direction, allowing the splitter housings to be installed side-by-side on the support plate 1 for subsequent wiring of the fiber optic splitter.
[0044] Reference Figure 5 The splitter housing 3 has a pull-out groove 301 on its side, and a positioning block 31 is provided in the middle of the pull-out groove 301. The positioning block 31 is integrally connected to the splitter housing 3 via an elastic sheet 311. The elastic sheet is elastic, and one end of the elastic sheet integrally connected to the splitter 3 has a bent section to facilitate elastic bending of the elastic sheet. The positioning block 31 is adapted to the positioning groove 201 for the splitter housing 3 to be snapped and fixed in the horizontal direction. A guide post 32 is fixed to the top of the positioning block 31, and the guide post 32 faces the pull-out component 4. The movement of the guide post 32 can drive the positioning block 31 to move, so that it crosses the positioning groove 201, allowing the splitter housing 3 to be released from the snap-fit fixation.
[0045] Reference Figure 6 Two limiting protrusions 33 are fixed on the side of the splitter housing 3. When the positioning block 31 of the splitter housing 3 enters the positioning groove 201, the two limiting protrusions 33 abut against the bottom of the two blocking protrusions 21 respectively. At this time, the blocking protrusions 21 at the top will fix the splitter housing 3 vertically.
[0046] Reference Figure 7Two first fixing members 34 are fixedly connected to the side of the splitter housing 3. The first fixing members 34 are L-shaped. The pull-out member 4 is connected to the splitter housing 3 through the first fixing members 34. A second fixing member 35 is also fixedly connected to the side of the splitter housing 3. The second fixing member 35 is also L-shaped. The second fixing member 35 is on the same horizontal plane as the first fixing member 34 and together with the first fixing member 34, it supports and fixes the splitter housing 3. In addition, the second fixing member 35 has a through-hole 302. The pull-out member 4 has several circular protrusions 36 on its side. The circular protrusions 36 pass through the through-hole 302 and are limited by the through-hole 302. By the circular protrusions 36 passing through the through-hole 302, the pull-out member 4 is restricted from detaching from the side of the splitter housing 3 in the vertical direction. The pull-out member 4 can only move along the length direction of the through-hole 302.
[0047] Reference Figure 7 The bottom of the splitter housing 3 has two limiting grooves 303, both of which are adapted to the limiting strips 2. A single splitter housing 3 requires three limiting strips 2 to be snapped and fixed to the support plate 1. That is, when the splitter housing 3 is snapped in the length direction of the limiting strips 2, two limiting grooves 303 can pass through two limiting strips 2, and the remaining limiting strip 2 is then used for snapping and fixing. Furthermore, the splitter housing 3 can also be adapted to any limiting strip 2, allowing the number and position of the splitter housings 3 installed on the support plate 1 to be changed according to actual conditions, thereby improving the efficiency of fiber optic splitter assembly and disassembly.
[0048] Reference Figure 8 and Figure 9The pull-out component 4 is installed on the side of the splitter housing 3 along its length direction via a first fixing member 34 and a second fixing member 35. One end of the pull-out component 4 has a first handle 41 with anti-slip texture 401, and the other end has a second handle 42 in a hook shape. When the splitter housing 3 needs to be removed from the top of the support plate 1, either the first handle 41 or the second handle 42 can be pulled, making the assembly and disassembly of the fiber optic splitter more convenient. Furthermore, the anti-slip texture 401 of the first handle 41 and the hook shape of the second handle 42 both improve stability when pulling the first handle 41 or the second handle 42. A guide adjustment groove 402 is provided in the middle of the pull-out component 4, facing the side of the splitter housing 3. A guide post 32 faces the guide adjustment groove 402 and can slide along the groove surface of the guide adjustment groove 402. Adjustment blocks are provided at both ends of the guide adjustment groove 402, and transmission springs 43 are inserted through the adjustment blocks. The transmission springs 43 abut against the side wall of the pull-out groove 301. If you want to remove the splitter housing 3 from the support plate 1, you can pull the pull-out piece 4. At this time, the transmission spring 43 is continuously compressed, causing the pull-out piece 4 to drive the guide post 32 to move along the inner groove direction of the guide adjustment groove 402, so that the positioning block 31 retracts again and disengages from the positioning groove 201, thus achieving the disassembly effect.
[0049] The implementation principle of the pull-and-click structure in this embodiment is as follows: When the splitter housing 3 needs to be installed on the support plate 1, firstly, the two limiting grooves 303 at the bottom of the splitter housing 3 are fitted with the two limiting strips 2, and then the side of the splitter housing 3 is pressed against another limiting strip 2. Finally, the splitter housing 3 is continuously pushed along the length of the limiting strip 2 until it is clicked. As the splitter housing 3 moves, the limiting protrusions 33 on the side of the splitter housing 3 also move. The positioning block 31 on the side begins to touch the blocking protrusion 21 and continuously retreats along the trapezoidal slope of the blocking protrusion 21. After passing the blocking protrusion 21, the positioning block 31 reaches the positioning groove 201, at which point the positioning block 31 is fixed horizontally by the positioning groove 201. The two limiting protrusions 33 are also respectively set at the bottom of the two blocking protrusions 21, at which point the top blocking protrusion 21 will play a vertical fixing role for the splitter housing 3. When it is necessary to remove the splitter housing 3 from the support plate 1, the pull-out component 4 can first be moved along the length direction of the limiting strip 2 by pulling the first handle 41 or the second handle 42. The moving limiting strip 2 causes the transmission spring 43 to be continuously compressed, which in turn drives the guide post 32 to move along the inner groove direction of the guide adjustment groove 402. The movement of the guide post 32 causes the positioning block 31 to retract again and disengage from the positioning groove 201, so that the splitter housing 3 is no longer locked to the support plate 1. This achieves the disassembly effect, effectively improving the disassembly and assembly efficiency of the fiber optic splitter.
[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
