[0050] The following will be further described in detail with reference to the attached Figures 1-3 This application will be further described in detail.

[0051] The embodiment of the present application discloses an intensive transport cable guide box for media equipment. Referring to Figure 1 , the transport cable guide box includes a box body 1 with an upward opening and a cover body 2 for opening and closing the top opening of the box body 1.

[0052] The box body 1 includes a bottom plate 11 and an annular frame 12.

[0053] The bottom plate 11 can be a horizontally arranged rectangular plate, circular plate, etc. In this embodiment, the bottom plate 11 is a rectangular plate, and the annular frame 12 is a rectangular frame fixedly connected to the upper surface of the bottom plate 11.

[0054] The annular frame 12 includes a main body portion 121 and a disassembly and assembly portion 122. A cargo opening 1211 for cooperating with the disassembly and assembly portion 122 is provided on one side of the main body portion 121. The disassembly and assembly portion 122 is arranged at the cargo opening 1211 to realize the opening and closing of the cargo opening 1211, and the disassembly and assembly portion 122 is detachably installed on the main body portion 121.

[0055] The disassembly and assembly portion 122 can be detachably fixed to the main body portion 121 by a plurality of screws.

[0056] In this embodiment, a slideway 1212 for cooperating with the disassembly and assembly portion 122 is provided on the main body portion 121 at the cargo opening 1211. The slideway 1212 is arranged along the height direction of the box body 1, and the disassembly and assembly portion 122 is slidably connected into the slideway 1212.

[0057] The slideway 1212 can be a "C"-shaped steel channel fixedly connected to the main body portion 121. In order to save the occupied space of the slideway 1212, in this embodiment, the slideway 1212 is arranged as two grooves opened in the main body portion 121, and the two grooves are respectively located on both sides of the cargo opening 1211. Both sides of the disassembly and assembly portion 122 extend into the two grooves respectively, and the disassembly and assembly portion 122 is slidably connected to the main body portion 121 of the annular frame 12.

[0058] The cover body 2 is hinged to the top position of the main body portion 121.

[0059] When it is necessary to put goods into the box body 1 or take goods out of the box body 1, the cover body 2 can be opened, then the disassembly and assembly portion 122 can be removed from the main body portion 121, and then the goods can be more easily put into or taken out of the box body 1 through the cargo opening 1211.

[0060] A number of threaded members 1213 are passed through the main body portion 121. The threaded members 1213 pass through the main body portion 121 and extend into the slideway 1212 and abut against the disassembly and assembly portion 122, and the disassembly and assembly portion 122 is pressed and fixed by the threaded members 1213. In order to facilitate the screwing of the threaded members 1213, the threaded members 1213 in this embodiment are wing bolts.

[0061] In order to facilitate the movement of the box body 1, universal wheels 111 are installed at the four corners of the lower surface of the bottom plate 11 of the box body 1.

[0062] A number of observation hole areas 123 are provided on the annular frame 12 of the box body 1, and the number of observation hole areas 123 are evenly spaced around the axis of the annular frame 12. Each observation hole area 123 includes a plurality of observation holes, and through the observation holes, it is convenient for the staff to observe the filling situation of the goods in the box body 1.

[0063] When using a transport box for outdoor cargo transportation, external dust and debris may enter the box body 1 through the observation holes. Therefore, a number of baffles 3 are provided on the annular frame 12. The baffles 3 are made of transparent materials, such as transparent glass. The number of baffles 3 corresponds one-to-one with the number of observation hole areas 123. The baffles 3 are used to block the observation hole areas 123 to reduce the entry of external debris into the box body 1.

[0064] Refer to Figure 2 , a plurality of installation grooves 124 for installing the baffles 3 are provided on the upper surface of the annular frame 12. The plurality of installation grooves 124 correspond one-to-one with the plurality of observation hole areas 123. The installation grooves 124 penetrate through the observation holes. The baffles 3 are inserted into the installation grooves 124.

[0065] When the baffles 3 are inserted into the installation grooves 124, on the one hand, it reduces the occupation of the external space by the baffles 3, and on the other hand, it can also form a certain protective effect on the baffles 3.

[0066] Refer to Figure 2 , a boosting component 4 is provided in the installation groove 124. The boosting component 4 can push the baffle 3 upward so that the top of the baffle 3 extends out of the installation groove 124 for the staff to take out the baffle 3 from the installation groove 124.

[0067] Specifically, a mounting groove 1241 for installing the boosting member 41 is provided on the bottom wall of the installation groove 124. The boosting component 4 is installed in the mounting groove 1241. The boosting component 4 includes a boosting member 41 and an elastic member 42. The boosting member 41 is arranged in the mounting groove 1241, and the boosting member 41 is slidably connected to the annular frame 12. The elastic member 42 is fixedly connected between the boosting member 41 and the annular frame 12.

[0068] A gland 5 is provided at the top position of the installation groove 124. The gland 5 presses the baffle 3 tightly, and the gland 5 is detachably connected to the annular frame 12. Specifically, the gland 5 and the annular frame 12 can be detachably installed together by screws or bolts.

[0069] After the gland 5 presses the baffle 3 into the installation groove 124, the elastic member 42 stores energy. When the gland 5 releases the fixed relationship with the annular frame 12, the elastic member 42 pushes the top of the baffle 3 out of the installation groove 124 through the boosting member 41.

[0070] In order to reduce the occupation of the external space by the gland 5, a hidden groove 125 for cooperating with the gland 5 is provided at the notch of the installation groove 124. The gland 5 is arranged in the hidden groove 125, and the upper surface of the gland 5 is flush with the upper surface of the annular frame 12.

[0071] There are two sets of boosting components 4, and the two boosting members 41 are respectively located on both sides of the baffle 3. Correspondingly, there are two installation slots 1241, and the two boosting components 4 respectively correspond to the two installation slots 1241 one by one.

[0072] When the baffle 3 needs to be taken out from the installation slot 124, the two boosting members 41 can boost the baffle 3 from both sides of the baffle 3, so that the top of the baffle 3 extends out of the installation slot 124 more smoothly.

[0073] A fixing mechanism 6 for fixing the baffle 3 is further provided in the installation slot 124. There are two sets of fixing mechanisms 6, and the two sets of fixing mechanisms 6 respectively correspond to the two sets of boosting components 4 one by one. There are two layout areas 126 in the installation slot 124, and the two layout areas 126 respectively correspond to the two sets of fixing mechanisms 6 one by one.

[0074] Refer to Figure 3 , the fixing mechanism 6 includes clamping plates 61 respectively arranged on both sides of the baffle 3, and the two clamping plates 61 are symmetric about the baffle 3.

[0075] The layout area 126 includes two layout slots 1261, and the two layout slots 1261 respectively correspond to the two clamping plates 61 in the fixing mechanism 6 one by one. And the bottom of the layout slot 1261 is communicated with the installation slot 1241. The clamping plate 61 is arranged in the layout slot 1261, and a connecting member 613 is provided between the bottom of the clamping plate 61 and the boosting member 41. The two ends of the connecting member 613 are respectively hinged to the clamping plate 61 and the boosting member 41.

[0076] A track 1262 is arranged in the layout slot 1261 along the depth direction of the layout slot 1261. A guiding member 612 cooperating with the track 1262 is fixedly connected to the baffle 3, and the guiding member 612 is slidably connected into the track 1262.

[0077] When the gland 5 presses the baffle 3 into the installation slot 124, the baffle 3 drives the boosting member 41 to move downward. At this time, the boosting member 41 drives the clamping plate 61 to move towards the baffle 3 through the connecting member 613. When the bottom of the baffle 3 abuts against the bottom wall in the installation slot 124, the two clamping plates 61 clamp and fix the baffle 3.

[0078] When the gland 5 releases the pressing effect on the baffle 3, the boosting member 41 pushes the baffle 3 to move upward under the action of the elastic member 42, and the boosting member 41 simultaneously pushes the clamping plate 61 to move away from the baffle 3. After the top of the baffle 3 extends out of the installation slot 124, the staff can take out the baffle 3 from the installation slot 124.

[0079] One side of the clamping plate 61 facing the baffle 3 is fixedly connected with an elastic pad 611. After the two clamping plates 61 clamp the baffle 3, the elastic pad 611 is in soft contact with the baffle 3, which can minimize the damage to the baffle 3 as much as possible, and at the same time can also increase the fixing effect of the fixing component on the clamping plate 61 as much as possible.

[0080] Referring to Figure 2 , additional grooves 127 are formed on the side walls on both sides of the baffle 3. The two additional grooves 127 respectively correspond to the two installation grooves 1241 one by one. The installation groove 1241 is communicated with the additional groove 127, and the boosting member 41 extends into the additional groove 127. At the same time, a mounting hole 128 is formed on the upper wall in the additional groove 127, and a pressure rod 7 for pressing the boosting member 41 is inserted into the mounting hole 128. The pressure rod 7 is detachably mounted to the annular frame 12.

[0081] After the baffle 3 is installed in the installation groove 124, the pressure rod 7 presses the boosting member 41, which can minimize the clamping force of the pressing cover 5 and the boosting member 41 on the baffle 3, so that the baffle 3 can be more stable. At the same time, during the process of installing the baffle 3 into the installation groove 124, the staff does not need to use the pressing cover 5 to push the baffle 3 downward anymore. After the staff uses the pressure rod 7 to push the boosting member 41 downward, the pressure rod 7 can be fixed, further reducing the damage to the baffle 3 during the process of arranging the baffle 3 in the installation groove 124.

[0082] The pressure rod 7 can be detachably fixed to the annular frame 12 by bolts or screws, that is, the bolts extend into the mounting hole 128 on the outer peripheral surface of the annular frame 12 to press the pressure rod 7.

[0083] Referring to Figure 2 , in this embodiment, the method of fixing the pressure rod 7 to the annular frame 12 is: the cross-section of the pressure rod 7 is circular, and the pressure rod 7 includes a rod main body 71 and a sub-rod 72 arranged coaxially. The diameter of the cross-section of the sub-rod 72 is smaller than the diameter of the cross-section of the main body part 121.

[0084] The rod main body 71 is slidably connected to the mounting hole 128. A screw hole 129 adapted to the sub-rod 72 is formed on the bottom wall in the installation groove 1241. The end face of the low end of the rod main body 71 abuts against the boosting member 41, and the bottom end of the sub-rod 72 is threadedly connected to the annular frame 12 through the screw hole 129.

[0085] Furthermore, a connection hole 411 adapted to the sub-rod 72 is formed on the boosting member 41. The sub-rod 72 of the pressure rod 7 passes through the connection hole 411, and the sub-rod 72 of the pressure rod 7 is slidably connected to the boosting member 41.

[0086] The pressure rod 7 can keep the booster 41 in a horizontal state while pushing the booster 41 downward, and avoid the booster 41 tilting to one side, which may reduce the contact area between the booster 41 and the baffle 3 and damage the baffle 3.

[0087] The implementation principle of a cable guide box for intensive transportation of media equipment in an embodiment of the present application is as follows: when the goods need to be placed in the box 1 or need to be moved out of the box 1, the staff opens the cover 2, and then screws the butterfly bolt used to fix the disassembly part 122, and then removes the disassembly part 122 from the box 1, and then puts the goods into the box 1 or moves them out of the box 1 through the cargo opening 1211. After the goods are transported, the disassembly part 122 is reinstalled into the box 1, and then the box 1 is fixed with butterfly bolts, and the top opening of the box 1 is closed with the cover 2, and then the box 1 is pushed to move.

[0088] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
