Description

Technical Field

[0001] The utility model relates to the technical field of demodulators, in particular to external protection equipment for a TDMA universal demodulator. Background Art

[0002] TDMA universal demodulator is a communication device specially used for processing time division multiple access signals. In TDMA communication system, multiple users share the same frequency resources and avoid mutual interference by sending and receiving signals in different time slices. Its main function is to extract and restore the original data or information from the received TDMA signal.

[0003] After searching, the Chinese patent with publication number CN220733176U discloses a communication transmission device that is easy to install. Although it is simple to use and has the effects of rainproof and heat dissipation outdoors, it is not convenient for staff to move the equipment, and locking the equipment with bolts and nuts is not conducive to the safety of the equipment. Non-staff may also open the equipment, which reduces the safety of the equipment. Therefore, the communication equipment is movably installed in the upper position inside the protective cabinet through a fixing component. The staff slides the communication equipment along the opening side of the limit seat into the interior of the protective cabinet. Under the action of the limit plate and the buffer spring, the communication equipment can be further clamped and fixed. Then, the handle is held to close the cabinet door and the protective cabinet, and locked with the lock body. Then, the protective cabinet is pushed to a suitable position, and the universal wheel brake pad is stepped on to brake and fix the protective cabinet. The heat dissipation port and heat dissipation window close to the communication equipment can play a heat dissipation role while reducing external rain and dust from entering the interior of the protective cabinet.

[0004] The above-mentioned protection for communication equipment still has shortcomings, and the general demodulator protection in daily use usually lacks special equipment for external protection of the demodulator, so that if a heavy object falls on the top of the demodulator, it is easy to have a direct impact on the demodulator, causing damage to the demodulator, making the demodulator less stable when transmitting signals, shortening the service life of the demodulator, and thus increasing the maintenance cost of the demodulator.

[0031] As attached Figure 1-6 As shown, an embodiment of the utility model is provided: a TDMA universal demodulator external protection device, comprising a demodulator protection shell 1, a stretching frame 2 is arranged on the left side of the top of the demodulator protection shell 1, a protective top 3 is arranged on the top of the stretching frame 2, a plurality of fixed shells 4 are fixedly connected to the top of the protective top 3, a sliding shell 6 is slidably connected to the inner side of the fixed shell 4, a plurality of first springs 5 ​​are fixedly connected to the top of the protective top 3, the other end of the first spring 5 is fixedly connected to the inner side of the sliding shell 6, two sliders 9 are fixedly connected to the bottom right side of the stretching frame 2, and the bottom right side of the stretching frame 2 The end is fixedly connected with a connecting rod 7, two slide grooves 8 are arranged on the right side of the top of the demodulator protective shell 1, the outer side of the slider 9 is slidably connected to the inner side of the slide groove 8, the front side of the front slider 9 is fixedly connected with an L-shaped plate 10, and the front side of the L-shaped plate 10 is penetrated by a bolt 24, and a plurality of threaded holes 11 are arranged on the top of the front side of the demodulator protective shell 1, so that when in use, the stretching frame 2 can be stretched to drive the protective top 3 to rise, so as to protect the top and reduce the direct impact force of the gravity factor on the demodulator. When not in use, the stretching frame 2 can be retracted to reduce the space occupied.

[0032] As attached Figure 5As shown, two fixed tubes 12 are fixedly connected to the left and right sides of the demodulator protective shell 1, and a sliding column 13 is slidably connected to the inner side of the fixed tube 12. A plurality of holes 15 are arranged at the front end of the sliding column 13, and a foot pad 14 is arranged at one end of the sliding column 13. The other end of the fixed tube 12 is fixedly connected to the mounting shell 16, and a clamping rod 17 is slidably connected to the inner side of the mounting shell 16. A limiting block 18 is fixedly connected to the middle part of the clamping rod 17, and a second spring 19 is fixedly connected to the front end of the limiting block 18. The outer side of the clamping rod 17 is arranged on the inner side of the second spring 19, and a pull rod 20 is fixedly connected to one end of the clamping rod 17. When water accumulates at the bottom of the demodulator protective shell 1, the sliding column 13 is adjusted so that the sliding column 13 slides inside the fixed tube 12, so as to lift the demodulator body, thereby reducing the phenomenon of water infiltration into the demodulator body, and facilitating moisture-proof protection.

[0033] As attached Figure 1 As shown, a moisture-proof plate 21 is provided at the inner bottom end of the demodulator protective shell 1, a storage plate 22 is fixedly connected to the inner bottom end of the demodulator protective shell 1, and a ventilation net 23 is fixedly connected to the rear side of the demodulator protective shell 1, which is beneficial to moisture-proof the demodulator body while ventilating and cooling the demodulator body, thereby reducing the accumulation of high temperature.

[0034] Working principle: When in use, place the demodulator on the surface of the storage plate 22, and then when the top needs to be protected, turn the bolt 24 so that the bolt 24 is disengaged from the inner side of the corresponding threaded hole 11, and then move the L-shaped plate 10, so that the L-shaped plate 10 drives the front slider 9 to slide inside the front slide groove 8, and under the drive of the connecting rod 7, the front slider 9 drives the connecting rod 7 to drive the rear slider 9 to move inside the slide groove 8, so that the stretching frame 2 is pushed by the slider 9 and then raised. After the slider 9 slides to a suitable position, the bolt 24 is screwed to the inner side of the corresponding threaded hole 11, so as to fix the position of the slider 9, so as to facilitate the lifting of the protective top 3. When the heavy object falls, the impact force generated by the heavy object firstly exerts an impact on the sliding shell 6 The impact causes the sliding shell 6 to be squeezed and thus squeezed to the first spring 5, and the impact force received by the sliding shell 6 impacts the protective top 3. Under the support of the stretching frame 2, it is convenient to protect the demodulator body. When water accumulates at the bottom of the demodulator protective shell 1, the pull rod 20 is pulled, so that the pull rod 20 drives the clamping rod 17 to disengage from the inner side of the corresponding hole groove 15, and the sliding column 13 is released. Then the sliding column 13 is slid so that the sliding column 13 slides on the inner side of the fixed tube 12. When the sliding column 13 is adjusted to an appropriate height, the pull rod 20 is released, so that the clamping rod 17 is clamped into the inner side of the corresponding hole groove 15 under the action of the second spring 19, which is convenient for fixing the position of the sliding column 13, thereby lifting the demodulator protective shell 1.
