DETAILED DESCRIPTION

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] Example 1:

[0019] like Figure 1 and Figure 2 As shown, Figure 1 This is the overall structural diagram of the hanging optical terminal. Figure 2 The figure is a schematic structural diagram of an upper positioning block 107. The present invention provides a hanging optical terminal, comprising a fixing plate 101, an optical terminal body 102, and an auxiliary mechanism. The optical terminal body 102 is provided with a plurality of connection ports 103. The auxiliary mechanism comprises a lower positioning block 104, a positioning plate 105, a lower fixing nut 106, an upper positioning block 107, an upper fixing nut 108, and an abutment device, wherein the abutment device comprises a connecting plate 109 and a clamping plate 110. The aforementioned solution can solve the problem that, in actual use, most existing hanging optical terminals are directly fixed to the wall via bolts. When the optical terminal is damaged and needs to be repaired, the optical terminal must be removed from the wall. However, when the operator tightens the bolts to remove the optical terminal, the bolts can easily loosen, even damaging the wall around the bolt holes, which is extremely detrimental to the installation and use of the optical terminal. It can be understood that the aforementioned solution can prevent wall damage when the optical terminal body is removed, facilitating the installation and use of the optical terminal.

[0020] In this embodiment, the optical terminal body 102 is provided with multiple connection ports 103. The optical terminal body 102 is located in front of the fixing plate 101. The fixing plate 101 is provided with mounting holes for easy pre-fixation to the wall by expansion bolts.

[0021] Among them, the lower positioning block 104 is detachably connected to the fixing plate 101 and is located on both sides of the bottom of the fixing plate 101. The positioning plate 105 is welded on the front side of the lower positioning block 104 and is detachably connected to the optical terminal body 102. The lower fixing nut 106 is threadedly connected to the external threaded column at the top of the lower positioning block 104 and is located on the side of the lower positioning block 104 close to the fixing plate 101. The upper positioning block 107 is detachably connected to the fixing plate 101 and is located on both sides of the top of the fixing plate 101. The upper fixing nut 108 is threadedly connected to the external threaded column at the bottom of the upper positioning block 107 and is located on the side of the upper positioning block 107 close to the fixing plate 101. The abutment device is arranged on the side of the upper positioning block 107 close to the optical terminal body 102. The bottom and top of the fixing plate 101 are symmetrically provided with T-shaped slots, and a circular through hole is provided in communication with the T-shaped slots, which facilitates the sliding installation of the lower positioning block 104 and the upper positioning block 107. The lower positioning block 104 and the upper positioning block 107 are of the same size. After the lower positioning block 104 slides into the T-shaped slot of the fixing plate 101, it is locked by installing the lower fixing nut 106. After the upper positioning block 107 slides into the T-shaped slot of the fixing plate 101, it is locked by installing the upper fixing nut 108. The two connecting short cylinders on the rear side of the positioning plate 105 are welded to the lower positioning block 104. The positioning plate 105 can directly facilitate the placement and support of the optical terminal body 102. After the upper positioning block 107 is fixed to the fixing plate 101 by the upper fixing nut 108, the abutment device can abut against the top shell of the optical terminal body 102 to achieve clamping.

[0022] Secondly, rectangular through-cavities are provided on the front, rear, left and right sides, and bottom of the positioning plate 105, and stepped grooves are provided on the upper side. The stepped grooves communicate with the rectangular through-cavities at the bottom. Since the housing of the optical terminal body 102 can be provided with heat dissipation holes simultaneously or separately on the rear, bottom, left and right sides during actual use, the rectangular through-cavities facilitate heat dissipation or cable routing, while the stepped grooves facilitate heat dissipation when heat dissipation holes are provided at the bottom. Furthermore, the optical terminal body 102 can be placed and removed easily.

[0023] Then, the connecting plate 109 is fixedly connected to the upper positioning block 107 and is located on the front side of the upper positioning block 107; the clamping plate 110 is fixedly connected to the connecting plate 109 and is located at the bottom of the connecting plate 109. The connecting plate 109 is fixed to the upper positioning block 107 by bolts with countersunk heads to facilitate smooth sliding of the upper positioning block 107, and the clamping plate 110 is fixed to the bottom of the connecting plate 109 by bolts with countersunk heads.

[0024] Finally, a rectangular rubber pad is bonded and fixed to the end surface of the clamping plate 110 that abuts against the top end surface of the optical terminal body 102. By bonding and fixing the rectangular rubber pad to the end surface of the clamping plate 110 that abuts against the top end surface of the optical terminal body 102, a buffering protection can be provided when the clamping plate 110 abuts against the housing of the optical terminal body 102.

[0025] The present invention solves the problem that in the actual use of existing hanging optical terminals, most of them are directly fixed to the wall by bolts for work use. When the optical terminal is damaged and the optical terminal is repaired, the optical terminal needs to be removed from the wall. When the staff twists the bolts to remove the optical terminal, it is easy to cause the bolts to loosen, and even damage the wall around the bolt holes, which is extremely unfavorable for the installation and use of the optical terminal. First, when installing the optical terminal body 102, the fixing plate 101 will be fixed to the wall in advance by expansion bolts, and then, the lower positioning block 104 will be fixed to the fixing plate 101 by the lower fixing nut 106, and then, the optical terminal body 102 will be directly placed in the stepped groove of the positioning plate 105, and further, the upper positioning block 107 will be locked on the fixing plate 101 by the upper fixing nut 108. At this time, the clamping plate 110 will just abut against the top of the optical terminal body 102 The upper fixing nut 108 is screwed off first, and then the upper positioning block 107 can be directly slid upward to remove the upper positioning block 107, so that the abutment device is no longer in contact with the optical terminal body 102, and the optical terminal body 102 can be directly removed upward from the positioning plate 105. At this time, the fixing bolts between the fixing plate 101 and the wall do not need to be removed, avoiding the frequent removal of the fixing bolts of the fixing plate 101 and the damage to the wall, thereby solving the problem that most of the existing suspended optical terminals are directly fixed to the wall for work use during actual use. When the optical terminal is damaged and the optical terminal is repaired, the optical terminal needs to be removed from the wall. When the staff twists the bolts to remove the optical terminal, it is easy to cause the bolts to loosen, and even damage the wall around the bolt hole, which is extremely unfavorable for the installation and use of the optical terminal.

[0026] Example 2:

[0027] like Figure 3 As shown, Figure 3 It is a schematic diagram of the overall structure of a hanging optical terminal. On the basis of the first embodiment, the utility model provides a hanging optical terminal, wherein the auxiliary mechanism further includes a right-angle piece 201 and a guard plate 202.

[0028] The right-angle piece 201 is fixedly connected to the upper positioning block 107 and is located on top of the upper positioning block 107. The guard plate 202 is welded to one side of the right-angle piece 201. One end of the right-angle piece 201 is welded to the guard plate 202, and the other end is fixed to the upper positioning block 107 via bolts. Since the connecting plate 109 has an L-shaped cross-section, its top short side can provide some support for the guard plate 202.

[0029] In this embodiment, the guard plate 202 is fixed on the right-angle piece 201 to protect the top of the optical terminal body 102, thereby preventing it from being damaged by vertical downward impact from the top, which is beneficial to improving the working stability and safety of the optical terminal body 102.
