DETAILED DESCRIPTION
[0026] The following description is used to fully explain the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.
[0027] See also Figure 1-2 The utility model provides a technical solution: a cable storage device, comprising:
[0028] A bottom plate 100, wherein the bottom plate 100 is provided with an exposed surface 100a and a hidden surface 100b opposite to each other, wherein the exposed surface 100a is provided with an annular receiving opening 101, and the edge of the receiving opening 101 extends toward one side of the hidden surface 100b to form an annular optical fiber receiving groove 102;
[0029] A through hole 103 is formed on one side of the inner wall of the optical fiber receiving groove 102 close to the receiving opening 101;
[0030] A limiting groove 104 is provided on the hidden surface 100 b of the bottom plate 100 . The limiting groove 104 is located on one side of the optical fiber receiving groove 102 in the radial direction. The limiting groove 104 extends toward the radial outer side of the optical fiber receiving groove 102 . The limiting groove 104 and the through hole 103 are arranged opposite to each other.
[0031] By providing an optical fiber receiving groove 102 extending toward one side of the hidden surface 100b on the exposed surface 100a, the optical fiber can be surrounded and received in the optical fiber receiving groove 102 when in use, wherein the head end or tail end of the optical fiber can pass through the through hole 103 located on the inner wall of the optical fiber receiving groove 102 to the limiting groove 104 located on the hidden surface 100b, and the limiting groove 104 limits the head end or tail end of the optical fiber to prevent the head end or tail end of the optical fiber from rebounding and tilting up, wherein the limiting groove 104 extending toward the radial outer side of the optical fiber receiving groove 102 can reduce the bending degree of the optical fiber to prevent the head end or tail end of the optical fiber from being damaged due to excessive bending angle.
[0032] Continue to see Figure 1 and 2 The inner ring edge 1011 of the receiving opening 101 is not lower than the outer ring edge 1012 of the receiving opening 101 , the through hole 103 is located on the side of the optical fiber receiving groove 102 close to the inner ring edge 1011 of the receiving opening 101 , and the limiting groove 104 is located on the inner side of the optical fiber receiving groove 102 in the radial direction.
[0033] Specifically, the inner ring edge 1011 of the receiving opening 101 is higher than the outer ring edge 1012 of the receiving opening 101. By limiting the height of the inner ring edge 1011 and the outer ring edge 1012 of the receiving opening 101, the inner wall of the optical fiber receiving groove 102 connected to the inner ring edge 1011 of the receiving opening 101 is higher than the inner wall of the optical fiber receiving groove 102 connected to the outer ring edge 1012 of the receiving opening 101, so that the optical fiber can be wound in the optical fiber receiving groove 102.
[0034] One side of the optical fiber storage groove 102 away from the storage opening 101 extends towards the radially inner side of the annular optical fiber storage groove 102, that is, the inner wall of the optical fiber storage groove 102 is inclined towards the radially inner side of the optical fiber storage groove 102. Preferably, the inner wall of the optical fiber storage groove 102 is a smooth inclined surface. During use, when the optical fiber contacts the inner wall of the higher side of the optical fiber storage groove 102, the optical fiber can slide down along the inclined inner wall of the optical fiber storage groove 102 to the bottom of the optical fiber storage groove 102, thereby realizing the limitation of the optical fiber by the optical fiber storage groove 102. Among them, the inner wall of the optical fiber storage groove 102 with a smooth inclined surface can avoid damaging the surface of the optical fiber during the contact with the optical fiber, avoiding the problem that the existing cable storage device has sharp edges at the contact part with the optical fiber and is easy to damage the optical fiber.
[0035] Furthermore, in the radial direction of the optical fiber storage groove 102, the extending dimension of the optical fiber storage groove 102 is not less than the dimension of the storage opening 101. To ensure that on the axial direction of the annular optical fiber storage groove 102, the inclined inner wall of the optical fiber storage groove 102 can limit the optical fiber wound in the optical fiber storage groove 102 and prevent the optical fiber from slipping out of the optical fiber storage groove 102. In addition, through the above limitation, the exposed part of the optical fiber is less, further avoiding damage caused by the contact between the surface of the optical fiber and foreign objects.
[0036] Specifically, the inner wall of the optical fiber storage groove 102 includes an inner side wall 1021, a bottom wall 1022, and an outer side wall 1023 that are sequentially connected between the inner ring edge 1011 and the outer ring edge 1012 of the storage opening 101. The inner side wall 1021 and the outer side wall 1023 are both inclined. The perforation 103 is located on one side of the inner side wall 1021 close to the inner ring edge 1011 of the storage opening 101. The inner side wall 1021 and the outer side wall 1023 are parallel to each other. The bottom wall 1022 is a smooth bottom wall 1022 in an arc shape, and the bottom wall 1022 is located on the radially inner side of the storage opening 101. During use, the optical fiber enters through the storage opening 101, the optical fiber contacts the inclined inner side wall 1021 and slides towards the direction of the inner wall, and the outer side wall 1023 also plays a role in guiding the optical fiber. The optical fiber stays inside the bottom wall 1022, and the inner side wall 1021 shields the optical fiber in the axial direction of the optical fiber storage groove 102.
[0037] The number of the perforations 103 is multiple, and the perforations 103 are arranged at intervals along the length direction of the optical fiber storage groove 102. Preferably, the interval distances between adjacent perforations 103 are equal. By limiting the number of the perforations 103, the head or tail ends of optical fiber cables with different lengths can be fixed securely. The number of the perforations 103 can be appropriately increased or decreased according to the actual situation.
[0038] The perforation 103 formed on the inner sidewall 1021 is blocked by the upper bottom plate 100 and is not easy to find during use. Further, the perforation 103 extends toward the radial outside of the optical fiber receiving groove 102, and the edge of the perforation 103 on the radial outside of the optical fiber receiving groove 102 is located on the radial outside of the receiving opening 101.
[0039] The limiting groove 104 is an annular limiting groove 104, and the cross-sectional dimension of the limiting groove 104 gradually decreases in a direction away from the center of the optical fiber receiving groove 102. When the head end or the tail end of the optical fiber enters the limiting groove 104, the inner wall of the limiting groove 104 can squeeze the head end or the tail end of the optical fiber, so as to facilitate the positioning of the head end or the tail end of the optical fiber.
[0040] The connection line between the end of the limiting groove 104 and the center position of the bottom of the optical fiber receiving groove 102 is parallel to the axis of the optical fiber receiving groove 102, that is, the end of the limiting groove 104 is located directly above the bottom of the optical fiber receiving groove 102. Through the above limitation, after the tail end of the optical fiber enters the limiting groove 104, it can move toward the radial outside to a greater extent, further reducing the bending degree of the optical fiber.
[0041] In another embodiment of the present utility model, the inner ring edge 1011 of the receiving opening 101 is not higher than the outer ring edge 1012 of the receiving opening 101, the perforation 103 is located on the side of the optical fiber receiving groove 102 close to the outer ring edge 1012 of the receiving opening 101, and the limiting groove 104 is located on the radial outside of the optical fiber receiving groove 102.
[0042] In yet another embodiment of the present utility model, the inner ring edge 1011 of the receiving opening 101 is flush with the outer ring edge 1012 of the receiving opening 101, the perforation 103 is located on both sides of the optical fiber receiving groove 102 close to the inner and outer ring edges 1012 of the receiving opening 101, and the limiting groove 104 is located on both sides in the radial direction of the optical fiber receiving groove 102.
[0043] Regarding the specific structure of the bottom plate 100, the bottom plate 100 is an integrally formed PVC bottom plate 100 with a uniform thickness, and the center of the bottom plate 100 coincides with the center of the annular optical fiber receiving groove 102.
[0044] Specifically, on the bottom plate 100, the outer peripheral edge of the bottom plate 100 and the outer ring edge 1012 of the storage opening 101 define the peripheral part of the bottom plate 100. The inner ring edge 1011 of the storage opening 101 and the outer ring edge 1012 of the storage opening 101 define the groove part of the bottom plate 100. The inner ring edge 1011 of the storage opening 101 defines the middle part of the bottom plate 100, wherein the middle part is parallel to the peripheral part, and the groove part is thermoformed between the peripheral part and the middle part.
[0045] In one embodiment of the present utility model, the bottom plate 100 is a bottom plate 100 made of PVC material. The bottom plate 100 is 25 cm long, 22 cm wide, with a total thickness of 1.4 cm, and the material thickness is 0.8 - 1 mm. The diameter of the optical fiber storage groove 102 is 18 cm.
[0046] A head end storage groove 105 is formed on the exposed surface 100a. The head end storage groove 105 extends towards the side of the hidden surface 100b, and the head end storage groove 105 communicates with the optical fiber storage groove 102. Preferably, the optical fiber storage groove 102 is an annular optical fiber storage groove 102, and the optical fiber storage groove 102 is tangent to the head end storage groove 105.
[0047] A plurality of through holes 103 are formed on the inner side of the head end storage groove 105, and the through holes 103 are arranged at intervals along the length direction of the head end storage groove 105.
[0048] To fix the head end of the optical fiber and prevent the optical fiber from falling off during transportation and disinfection, the cable storage device further includes:
[0049] An optical fiber buckle 106 is arranged at the opening of the head end storage groove 105. The optical fiber buckle 106 is located on at least one side in the width direction of the head end storage groove 105. The projection of the optical fiber buckle 106 in the vertical direction falls into the head end storage groove 105, and the optical fiber buckle 106 is arranged to be movable along the width direction of the head end storage groove 105 when being squeezed.
[0050] The optical fiber buckle 106 is an elastic optical fiber buckle 106. The optical fiber buckle 106 includes a first sub - buckle 1061 and a second sub - buckle 1062. The first sub - buckle 1061 and the second sub - buckle 1062 are respectively arranged on both sides in the width direction of the head end storage groove 105. The opposite sides of the first sub - buckle 1061 and the second sub - buckle 1062 are extrusion sides 106b, and the distance between the extrusion side 106b of the first sub - buckle 1061 and the extrusion side of the second sub - buckle 1062 is less than the opening width of the head end storage groove 105;
[0051] The upper edge of the extrusion side surface 106b is inclined towards the outer side in the width direction of the head-end storage groove 105.
[0052] Preferably, the side of the first sub-fastener 1061 and the second sub-fastener 1062 facing the head-end storage groove 105 is the limiting side surface 106a, the limiting side surface 106a is a smooth arc surface, the inner wall of the head-end storage groove 105 is a smooth arc surface, and the centers of the limiting side surface 106a and the head-end storage groove 105 coincide, so as to prevent the optical fiber fastener 106 from damaging the head end of the optical fiber on the device.
[0053] Preferably, the cross-sectional dimension of the optical fiber fastener 106 gradually decreases in a direction away from the bottom plate 100, ensuring that the optical fiber fastener 106 can be stably connected to the bottom plate 100. The optical fiber fastener 106 with a smaller cross-sectional dimension can generate a larger deformation when contacting the optical fiber connector, so that the optical fiber connector can enter the head-end storage groove 105 through the optical fiber fastener 106.
[0054] During use, the head end of the optical fiber extrudes the extrusion side surface 106b, and the optical fiber fastener 106 deforms outward in the width direction of the head-end storage groove 105 under the action of pressure, the distance between the extrusion side surfaces 106b increases, the head end of the optical fiber enters the area enclosed by the limiting side surface and the inner wall of the head-end storage groove 105, and the optical fiber fastener 106 resets under the action of elasticity to realize the limitation of the head end of the optical fiber.
[0055] In one embodiment of the present utility model, the number of the optical fiber fasteners 106 is two, and the optical fiber fasteners 106 are arranged at intervals along the length direction of the head-end storage groove 105.
[0056] Usage method: Place the head end of the optical fiber in the head-end storage groove 105, use the optical fiber fastener 106 to fix the head end of the optical fiber, then wind the tail end of the optical fiber clockwise into the optical fiber storage groove 102, and when there is still the last 1 / 4 turn of the winding length of the optical fiber, pass the tail end of the optical fiber through the through hole 103 into the limiting groove 104 to complete the storage of the optical fiber; when it is necessary to take out the optical fiber on the device, take out the head end of the optical fiber from the head storage groove and draw out the optical fiber from the optical fiber storage groove 102.
[0057] In summary, the utility model uses the annular optical fiber storage groove 102 to store the whole optical fiber on the bottom plate 100. The head end of the optical fiber is sunk and stored in the head storage groove and is firmly fixed by the optical fiber fastener 106. The tail end of the optical fiber is stored in the limiting groove 104 through the through hole 103, ensuring that the optical fiber is convenient to take, does not damage the optical fiber, and is convenient for subsequent cleaning, disinfection and transportation. The optical fiber stored on the bottom plate 100 has less exposed parts to the outside world, and can prevent the optical fiber from contacting with foreign objects and causing damage to the surface of the optical fiber.
[0058] The cable storage device has the following advantages:
[0059] The base plate 100 is made of PVC plastic for medical devices, which is corrosion-resistant and can be sterilized at 140°C for 10-15 minutes, meeting the requirements for high-temperature sterilization;
[0060] The diameter of the optical fiber storage groove 102 is 18 cm, which is much larger than the minimum bending radius of the optical fiber and will not cause the optical fiber to break, and is suitable for storing various optical fibers;
[0061] The optical fiber storage groove 102 and the limiting groove 104 can fix and store the optical fiber without the need for other devices such as buckles or tapes, thereby preventing the optical fiber from rebounding due to its own elasticity;
[0062] The optical fiber storage groove 102 and the head end storage groove 105 are both sunken grooves, which can reduce the risk of accidental breakage of the optical fiber lead-out portion, and also reduce the overall height of the storage tray.
