DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] The specific embodiments are given below.

[0027] Please refer to Figure 1 , Figure 3 - Figure 6 The utility model provides a kind of exhibition hall multi-node terminal equipment centralized control device, including centralized control sleeve shell 11 and the multiple groups of butt joint support plate 15 of fixed connection on the inner side wall surface of centralized control sleeve shell 11, isolation cavity 12 is arranged on the inner side wall surface of centralized control sleeve shell 11 and the outer side surface of butt joint support plate 15, limiting rod 14 is movably sleeved on the outer side surface of butt joint support plate 15, terminal device 13 is movably butt joint on the outer side surface of the top of butt joint support plate 15 and the inner side wall surface of centralized control sleeve shell 11, pad strip 152 is fixedly connected on the outer side surface of the top of butt joint support plate 15, U-shaped strip 153 is fixedly connected on the bottom surface of butt joint support plate 15 and movably butt joint on the outer side surface of the top of terminal device 13, butt joint recess 154 is formed on the inner side wall surface of one end of U-shaped strip 153, extrusion block 155 is movably sleeved on the outer side surface of butt joint recess 154.

[0028] When the new terminal equipment 13 is placed on the top surface of the pad strip 152 during work, the pad strip 152 pads the terminal equipment 13, so that a certain gap is left between the terminal equipment 13 and the butt joint support plate 15, thereby increasing the flow space and range of cold air. When the terminal equipment 13 is fixed, the extrusion block 155 is clamped into the inside of the U-shaped strip 153, and the inner side wall surface of the butt joint groove 154 is clamped with the surface of the extrusion block 155. As the extrusion block 155 continuously extends into the inside of the U-shaped strip 153, the extrusion block 155 will extend the U-shaped strip 153 on both sides, and the bottom surface of the U-shaped strip 153 can be firmly attached to the top surface of the terminal equipment 13, thereby limiting the position of the terminal equipment 13. The effect of using the U-shaped strip 153 to expand the surface of the terminal equipment 13 is achieved.

[0029] Further, as shown in Figures 1 to 6 The inner side wall surface of the central control sleeve 11 is provided with an inner recess a1 on both sides and in the isolation cavity 12. The inner wall surface of the inner recess a1 is fixedly connected with the elastic wire a2. The inner side wall surface of the inner recess a1 is fixedly connected with the contraction rod a3 on both side edge positions of the elastic wire a2. The elastic wire a2 and the contraction rod a3 are fixedly connected with the contraction rod a3 which is movably sleeved on the inner side wall surface of the inner recess a1. The inner side wall surface of the central control sleeve 11 is provided with an air port on one side edge position of the contraction rod a3. The outer side surface of the limiting rod 14 is movably sleeved in the inner side wall surface of the butt joint groove 156. One end of the limiting rod 14 is fixedly connected with the sealing plate 141 which is movably attached to the outer side surface of the central control sleeve 11. The outer side surface of the extrusion strip 142 is slidably connected to the inner side wall surface of the central control sleeve 11. The other end of the extrusion strip 142 is movably connected to the outer side surface of the contraction rod a3. The top surface of the central control sleeve 11 is fixedly connected with the circulating cold air machine 112. The two side surfaces of the central control sleeve 11 are fixedly connected with the partitioning and ventilating shell 111 which is arranged on the output end of the circulating cold air machine 112.

[0030] When the terminal device 13 is clamped into the independent isolation cavity 12, one end of the limiting rod 14 is clamped into the butt circular groove 156, and the sealing plate 141 on one end of the limiting rod 14 is matched to close the entrance of the isolation cavity 12. An independent closed cavity is formed in the isolation cavity 12. When the extrusion strip 142 on the outer surface of the sealing plate 141 extends into the isolation cavity 12, one end of the extrusion strip 142 is matched and extruded with the surface of the contraction rod a3. The extrusion strip 142 continuously extends to push and extrude the surface of the contraction rod a3, so that the contraction rod a3 slides on the inner side wall of the recess a1 to open the air port between the partitioned air-permeable shell 111 and the centralized control sleeve 11. After the sealing plate 141 is pulled out, the contraction rod a3 is pulled by the elastic wire a2 to close the air port again. The air port in the isolation cavity 12 can be closed and opened by pulling the sealing plate 141, which can independently open and close the cold air. The cold air in the circulating cold air machine 112 is injected into the centralized control sleeve 11 from the air port on the other side surface of the centralized control sleeve 11 to circulate and cool the terminal device 13 in the isolation cavity 12. The closed space reduces the leakage of cold air. After the cold air absorbs heat, it is discharged into the partitioned air-permeable shell 111 through the air port on the other side surface of the centralized control sleeve 11 to circulate and cool. The terminal device 13 is independently stored, the closed space reduces the leakage of cold air, and the other spaces do not leak cold air when the single isolation cavity 12 is opened.

[0031] Further, as shown in Figure 1 and Figures 3 to 6 The top surface of the lapping support plate 15 is provided with a sunken groove 151 on the bottom surface of the terminal device 13, and the side surface of the lapping support plate 15 is provided with a butt circular groove 156.

[0032] When the circulating cold air machine 112 is injected into the centralized control sleeve 11, the cold air hits the surface of the terminal device 13. At this time, the cold air flows from the upper and lower surfaces of the terminal device 13, and the space generated by the cushioning strip 152 and the space in the U-shaped strip 153 increase the flow space of the cold air, so as to wrap the surface of the terminal device 13 and cool it in all directions. The heat-absorbed air is discharged under the pushing of the subsequent cold air.

[0033] Working principle: when the new terminal equipment 13 is overlapped and placed on the top surface of the pad strip 152, the pad strip 152 matches the terminal equipment 13 for pad processing, so that a certain gap is left between the terminal equipment 13 and the overlapping support plate 15, so as to increase the flow space and range of cold air. When the terminal equipment 13 is fixed, the extrusion block 155 is clamped into the inside of the U-shaped strip 153, and the inside wall surface of the butt joint groove 154 is matched and clamped with the surface of the extrusion block 155. As the extrusion block 155 continuously extends into the inside of the U-shaped strip 153, the extrusion block 155 will extend the U-shaped strip 153 on both sides, and at the same time, the bottom surface of the U-shaped strip 153 can be firmly attached and adsorbed on the top surface of the terminal equipment 13, so as to limit the position of the terminal equipment 13, so as to achieve the effect of using the up and down expansion of the U-shaped strip 153 to extrude the surface of the terminal equipment 13, so that the terminal equipment 13 is firmly positioned on the top surface of the pad strip 152;

[0034] When the terminal equipment 13 is clamped into the independent isolation cavity 12, one end of the limiting rod 14 is clamped into the inside of the butt joint circular groove 156, and the sealing plate 141 on one end of the limiting rod 14 closes the entrance of the isolation cavity 12. An independent closed cavity is formed in the inside of the isolation cavity 12. As the extrusion strip 142 on the outside surface of the sealing plate 141 extends into the inside of the isolation cavity 12, the one end of the extrusion strip 142 is matched and extruded with the surface of the contraction rod a3. As the extrusion strip 142 continuously extends, it will push and extrude the surface of the contraction rod a3, so that the contraction rod a3 slides on the inside wall surface of the inward recess a1, and opens the air port between the partitioned air-permeable shell 111 and the centralized control sleeve 11. After the sealing plate 141 is pulled out, the contraction rod a3 will be pulled by the elastic wire a2, and the air port will be closed again. The effect of closing and opening the air port in the inside of the isolation cavity 12 by pulling the sealing plate 141 is achieved, so that the cold air in the circulating cold air machine 112 is injected into the inside of the centralized control sleeve 11 from the air port on the other side surface of the centralized control sleeve 11, and the terminal equipment 13 in the current isolation cavity 12 is cooled. The closed space reduces the leakage of cold air. After the heat source is absorbed by the cold air, it will be discharged into the inside of the partitioned air-permeable shell 111 from the air port on the other side surface of the centralized control sleeve 11 for circulating cooling treatment. The effect of storing the terminal equipment 13 independently is achieved, the closed space reduces the leakage of cold air, and when a single isolation cavity 12 in the other space is opened, the isolation cavity 12 in the other space will not leak cold air;

[0035] When the cold air filled in the circulating cold air blower 112 is filled into the inside of the centralized control sleeve 11, the cold air will impact on the surface of the terminal equipment 13, at this time, the cold air is divided by the terminal equipment 13, so that the cold air flows from the upper and lower surfaces of the terminal equipment 13, and then the flow space of the cold air is increased through the space generated by the cushioning strip 152 and the space in the U-shaped strip 153, so as to wrap the surface of the terminal equipment 13 and perform all-round cooling, and the heat-absorbed air will be discharged under the subsequent pushing of the cold air.

[0036] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
