Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 and Figure 4 This utility model discloses an adjustable reinforcing cover 1 for a fiber distribution box, comprising a cover body 10, an adjustable mounting unit 20, and at least one snap-fit ​​unit 30. The top end of the cover body 10 is rotatably connected to the top end of the mounting unit 20. The mounting unit 20 is used to hold the outer wall of the fiber distribution box 2 so that the cover body 10 covers the opening end of the fiber distribution box 2, and the cover body 10 can rotate relative to the fiber distribution box 2. The snap-fit ​​unit 30 includes a snap-fit ​​assembly 31 and a hook 32. The snap-fit ​​assembly 31 is disposed on the outer side wall near the top end of the mounting unit 20, and the hook 32 is disposed on the outer side wall of the cover body 10. The cover 10 is located on the same side. When the cover 10 is opened, the fastener assembly 31 and the hook 32 cooperate to fix the cover 10. On the one hand, by setting the installation unit 20, it is convenient to install the cover 10, which improves the service life of the equipment in the fiber distribution box 2 and reduces optical fiber signal interference. At the same time, by connecting the installation unit 20 with the fiber distribution box 2, damage to the aging fiber distribution box 2 is prevented, and the connection between the cover 10 and the fiber distribution box 2 is improved. On the other hand, by setting the buckle unit 30, when the cover 10 is opened, the fastener assembly 31 and the hook 32 cooperate to fix the cover 10, which facilitates construction.

[0026] It should be noted that the adjustable reinforcing cover 1 can be used on any fiber distribution box 2 without a cover, especially on aging fiber distribution boxes 2.

[0027] like Figure 1 As shown, there are two buckle units 30, wherein two buckle assemblies 31 are respectively disposed on the two outer side walls near the top of the mounting unit 20, and two hooks 32 are respectively disposed on the two opposite outer side walls of the cover 10.

[0028] Specifically, with Figure 1 Taking the orientation shown as an example, the side near the opening of the cover 10 (i.e. the left side of the cover 10) is rotatably connected to the mounting unit 20 via a hinge. Since the widths of different models of fiber distribution boxes 2 are not consistent, the mounting unit 20 can be adjusted according to the width of the fiber distribution box 2 to be installed, so that the mounting unit 20 can be used for different models of fiber distribution boxes 2, thereby improving the applicability of the adjustable reinforcing cover 1.

[0029] The installation process of the adjustable reinforcing cover 1 for the fiber distribution box 2 provided in this embodiment is as follows: the installation unit 20 is fastened to the outer peripheral wall of the fiber distribution box 2, and the cover 10 is rotatably connected to the installation unit 20 through a hinge. The cover 10 covers the open end of the fiber distribution box 2 and can rotate relative to the fiber distribution box 2. This setting solves the equipment protection problem caused by the missing cover of the aging fiber distribution box 2, improves the service life of the equipment in the fiber distribution box 2, and reduces optical fiber signal interference.

[0030] Furthermore, in this embodiment, the hook 32 is bolted to the outer side wall near the top of the cover 10. During use, when constructing, the cover 10 is lifted and the top of the buckle assembly 31 is hooked onto the hook 32 to fix the cover 10 and prevent the cover 10 from flipping downwards, thus facilitating construction workers to carry out construction.

[0031] Continue to refer to Figure 2 In this embodiment, the mounting unit 20 includes a connecting plate 21 and two clamping units 22 disposed opposite to each other. The connecting plate 21 is rotatably disposed on one side near the top of the cover 10, and the cover 10 can rotate relative to the connecting plate 21. Mounting screws 211 are respectively disposed on the top surfaces of opposite ends of the connecting plate 21. The two clamping units 22 are respectively disposed on opposite sides of the connecting plate 21, and the top of the clamping unit 22 is sleeved on the mounting screws 211. The clamping unit 22 can slide relative to the connecting plate 21 and the mounting screws 211 to adjust the mounting unit 20 along the first... The dimension of the first direction 50; when the clamp unit 22 slides to the preset position along the first direction 50 of the cover 10, the top end of the mounting screw 211 passes through the clamp unit 22 and is threadedly connected to the mounting nut to lock the clamp unit 22; the length of the clamp unit 22 along the second direction 60 of the cover 10 is greater than or equal to the length of the fiber distribution box 2 along the second direction 60 of the cover 10; by setting the length of the clamp unit 22 along the second direction 60 of the cover 10 to be greater than or equal to the length of the fiber distribution box 2 along the second direction 60 of the cover 10, the firmness of the connection between the cover 10 and the fiber distribution box 2 is improved.

[0032] It should be noted that the first direction 50 of the cover 10 is the width direction of the cover 10, the second direction 60 of the cover 10 is the length direction of the cover 10, and the third direction 70 of the cover 10 is the thickness direction of the cover 10. The first direction 50, the second direction 60 and the third direction 70 of the cover 10 are perpendicular to each other.

[0033] Specifically, such as Figure 1 As shown, two mounting screws 211 are respectively provided on the top surface of opposite ends of the connecting plate 21, and the two mounting screws 211 are spaced apart. The connecting plate 21 is rotatably connected to the cover 10 via a hinge.

[0034] During use, the bottom surface of the connecting plate 21 is in contact with the top surface of the fiber distribution box 2 to be installed.

[0035] The bottom end of the mounting screw 211 is connected to the top surface of the connecting plate 21, and the top end of the mounting screw 211 extends upward along the second direction 60. During the installation process, according to the size of the fiber distribution box 2 along the first direction 50, the two clamping units 22 are slid until the size of the mounting unit 20 along the first direction 50 matches the size of the fiber distribution box 2 along the first direction 50. The mounting unit 20 is fastened to the outer wall of the fiber distribution box 2, and the inner wall of the mounting unit 20 abuts against the outer wall of the fiber distribution box 2. The mounting nut is screwed onto the mounting screw 211 to lock the clamping unit 22. The cover 10 is rotated so that the cover 10 covers the open end of the fiber distribution box 2.

[0036] In this embodiment, the length of the clamp unit 22 along the second direction 60 is equal to the length of the fiber distribution box 2 along the second direction 60. That is to say, the total length of the clamp unit 22 is basically the same as the total length of the fiber distribution box 2.

[0037] Furthermore, in this embodiment, the clamping unit 22 includes a first clamping assembly 221 for clamping onto the outer wall of the fiber distribution box 2 and at least one second clamping assembly 222 for fixing the first clamping assembly 221 onto the fiber distribution box 2. The top end of the first clamping assembly 221 is sleeved on the mounting screw 211, and the first clamping assembly 221 can slide relative to the mounting screw 211. The second clamping assembly 222 is slidably connected to the first clamping assembly 221, and the second clamping assembly 222 slides along the third direction 70 of the cover 10. The length of the first clamping assembly 221 along the second direction 60 of the cover 10 is greater than or equal to the length of the fiber distribution box 2 along the second direction 60 of the cover 10.

[0038] like Figure 2 As shown, each clamp unit 22 may include two second clamp assemblies 222. Of course, each clamp unit 22 may include three or four second clamp assemblies 222.

[0039] During installation, according to the width of the fiber distribution box 2 to be installed, the first clamp assembly 221 slides along the first direction 50, and the first clamp assembly 221 drives the second clamp assembly 222 to move along the first direction 50 until the first clamp assembly 221 moves to the preset position, and then the first clamp assembly 221 is locked by the installation nut; then according to the thickness of the fiber distribution box 2 to be installed, the second clamp assembly 222 slides along the third direction 70 until the second clamp assembly 222 slides to a certain position, and then the second clamp assembly 222 is locked so that the first clamp assembly 221 and the second clamp assembly 222 are both fastened to the fiber distribution box 2 to be installed, and the inner sidewalls of the first clamp assembly 221 and the second clamp assembly 222 abut against the outer sidewall of the fiber distribution box 2 to be installed.

[0040] In this embodiment, the length of the first clamp assembly 221 along the second direction 60 is equal to the length of the fiber distribution box 2 along the second direction 60. That is to say, the total length of the first clamp assembly 221 is basically the same as the total length of the fiber distribution box 2.

[0041] Further, in this embodiment, the first clamp assembly 221 includes a horizontal plate 2211, a vertical plate 2212, and at least one fixing screw 2213. A first elongated hole 2214 is provided on the horizontal plate 2211, penetrating the horizontal plate 2211. The first elongated hole 2214 is adapted to the mounting screw 211, which passes through the first elongated hole 2214 and can slide along it. The bottom surface of the horizontal plate 2211 is in contact with the top surface of the connecting plate 21, and the horizontal plate 2211 can slide relative to the mounting screw 211 and the mounting plate. One end of the horizontal plate 211 is connected to the top of the vertical plate 2212. The horizontal plate 2211 and the vertical plate 2212 together form an L-shape. The bottom end of the vertical plate 2212 extends downward along the second direction 60 of the cover 10. The length of the vertical plate 2212 along the second direction 60 of the cover 10 is greater than or equal to the length of the fiber distribution box 2 along the second direction 60 of the cover 10. The inner side wall of the vertical plate 2212 is attached to the outer side wall of the fiber distribution box 2. A fixing screw 2213 is provided on the outer side wall of the vertical plate 2212. The fixing screw 2213 passes through the second clamp assembly 222. The second clamp assembly 222 can slide relative to the fixing screw 2213.

[0042] During installation, the horizontal plate 2211 slides, and when the horizontal plate 2211 drives the vertical plate 2212 and the second clamp assembly 222 to slide to the preset position, the mounting nut is screwed onto the mounting screw 211, and the bottom end of the mounting nut abuts against the top surface of the horizontal plate 2211 to lock the horizontal plate 2211.

[0043] Specifically, the horizontal plate 2211 is arranged parallel to the connecting plate 21, the horizontal plate 2211 is partially placed on the connecting plate 21, and the first elongated hole 2214 extends along the first direction 50.

[0044] In this embodiment, the length of the vertical plate 2212 along the second direction 60 is equal to the length of the fiber distribution box 2 along the second direction 60. That is to say, the total length of the vertical plate 2212 is equal to the total length of the fiber distribution box 2.

[0045] It should be noted that the number of first elongated holes 2214 on each horizontal plate 2211 is basically the same as the number of mounting screws 211 on each end of the connecting plate 21, and the first elongated holes 2214 and the mounting screws 211 are set in a one-to-one correspondence.

[0046] Specifically, each vertical plate 2212 may be provided with 4 fixing screws 2213. Of course, each vertical plate 2212 may also be provided with 6 or 8 fixing screws 2213.

[0047] The centerline of the fixing screw 2213 is parallel to the first direction 50. One end of the fixing screw 2213 is connected to the outer wall of the vertical plate 2212, and the other end of the fixing screw 2213 extends outward along the first direction 50.

[0048] Furthermore, in this embodiment, the second clamp assembly 222 includes a first clamp portion 2221 and a second clamp portion 2222. One end of the first clamp portion 2221 has at least one second elongated hole 2223, which passes through the first clamp portion 2221. One end of the second clamp portion 2222 has at least one third elongated hole 2224, which passes through the second clamp portion 2222. The end of the fixing screw 2213 facing away from the vertical plate 2212 passes through the second elongated hole 2223 and the third elongated hole 2224 in sequence. Both the first clamp portion 2221 and the second clamp portion 2222 can slide relative to the fixing screw 2213 to adjust the second clamp... The clamp assembly 222 extends along the third direction 70 of the cover 10. When both the first clamp part 2221 and the second clamp part 2222 slide along the third direction 70 of the cover 10 to the predicted position, the end of the fixing screw 2213 away from the vertical plate 2212 passes through the second elongated hole 2223 and the third elongated hole 2224 and the fixing nut in sequence to lock the first clamp part 2221 and the second clamp part 2222. By setting the first clamp part 2221 and the second clamp part 2222, the first clamp part 2221 and the second clamp part 2222 cooperate to fix the first clamp assembly 221 on the fiber distribution box 2, which further improves the firmness of the connection between the cover 10 and the fiber distribution box 2.

[0049] Specifically, the second elongated hole 2223 and the third elongated hole 2224 both extend along the third direction 70, and the number of the second elongated hole 2223 and the third elongated hole 2224 is the same as the number of the fixing screws 2213.

[0050] The first clamping part 2221 includes a first fastening plate 2225 and a second fastening plate 2226. The first fastening plate 2225 has a second elongated hole 2223, which passes through the first fastening plate 2225. The side wall of the first fastening plate 2225 is attached to the outer side wall of the vertical plate 2212. The end of the first fastening plate 2225 away from the second elongated hole 2223 extends along a third direction 70 and is fixedly connected to one end of the second fastening plate 2226. The first fastening plate 2225 and the second fastening plate 2226 together form an L-shape. The inner side wall of the second fastening plate 2226 is used to abut against the outer side wall of the fiber distribution box 2 away from its opening end.

[0051] The second clamping part 2222 includes a first fixing plate 2227, a second fixing plate 2228, and a third fixing plate 2229. A first fastening plate 2225 is clamped between the first fixing plate 2227 and the vertical plate 2212. A third elongated hole 2224 is provided on the first fixing plate 2227, and the third elongated hole 2224 passes through the first fixing plate 2227. One end of the first fixing plate 2227 away from the third elongated hole 2224 extends along a third direction 70 and is connected to one end of the second fixing plate 2228. One end of the second fixing plate 2228 away from the first fixing plate 2227 extends along a first direction 50 and is connected to one end of the third fixing plate 2229. The other end of the third fixing plate 2229 extends along a third direction 70. The first fixing plate 2227, the second fixing plate 2228, and the third fixing plate 2229 together form a slot, and the side wall of the open end of the fiber distribution box 2 is clamped in the slot.

[0052] During the installation process, Figure 2 Taking the orientation shown as an example, according to the thickness of the fiber distribution box 2 to be installed, slide the first fastening plate 2225 and the first fixing plate 2227. The first fastening plate 2225 drives the second fastening plate 2226 to slide to the left side of the fiber distribution box 2 until the inner side wall of the second fixing plate 2228 abuts against the outer side wall of the fiber distribution box 2 away from its opening end. The first fixing plate 2227 drives the second fixing plate 2228 and the third fixing plate 2229 to slide to the right side of the fiber distribution box 2 until the side wall of the opening end of the fiber distribution box 2 is locked in the slot. Then, tighten the fixing nut onto the fixing screw 2213 to lock the first fastening plate 2225 and the first fixing plate 2227.

[0053] Continue to refer to Figure 3In this embodiment, the buckle assembly 31 includes a U-shaped mounting bracket 311, a rotating handle 312, and a buckle body 313. The U-shaped mounting bracket 311 is connected to the outer wall of the mounting unit 20. One end of the rotating handle 312 is inserted into the U-shaped mounting bracket 311 and can rotate relative to the U-shaped mounting bracket 311. One end of the buckle body 313 is rotatably connected to the rotating handle 312, and the other end of the buckle body 313 is used for detachable connection with the hook body 32. Rotating the rotating handle 312 causes the buckle body 313 to move, thereby enabling the buckle body 313 to engage or disengage from the hook body 32.
