Description

Technical Field

[0001] The invention relates to the field of tents, in particular to a large-scale tent air conditioner for outdoor use. Background Art

[0002] Tent air conditioners are mainly used in exhibition tents, military tents, disaster relief tents, field work tents and other places. Since the tents are not in a fixed position and need to be moved frequently, the integrated structure only requires power supply and pipeline connection for use. Unlike traditional air conditioners, there is no need for professional installers to install and debug, thus avoiding the problems of installation and relocation.

[0003] When a large tent is used outdoors in the summer, the air flow inside the tent is poor and the temperature inside the tent will be higher than that outside. Therefore, the tent needs to be equipped with air conditioning. The air outlet needs to be set in the middle or above the tent to ensure that the gas can quickly enter the room. The fan is not set on the air outlet of the tent, otherwise it will increase the load of the tent; due to the position of the air outlet, a fan is needed to supply air to ensure the amount of air entering the large tent. This will cause the condensed water to be discharged inside the integrated body. Therefore, additional condensed water discharge is required; the air supply duct is installed on the outside of the large tent. When encountering windy weather, the air supply duct is easy to shake, and the shaking of the air supply duct is easy to detach from the outer shell or the connection between the ducts.

[0014] Beneficial effects:

[0015] (1) The air inlet assembly is provided to facilitate the delivery of cold air from the inside of the casing to the inside of the large tent. When the air inlet assembly delivers cold air, the wind force is sufficient, and when the air inlet assembly delivers air, the air inlet assembly is cooled. The telescopic tube is a bellows, and the bellows is discharged from one side by the provided tube release mechanism. After being discharged, the bellows is connected to the other side of the tube release mechanism. The locking mechanism provided on the tube release mechanism locks the telescopic tube on the tube release mechanism and the flange. The locking mechanism provided can stabilize the telescopic tube when the telescopic tube is extended, and can stabilize the telescopic tube when the wind blows, so that the telescopic tube does not shake. A supporting mechanism is provided below the tube release mechanism, and the supporting mechanism can support the tube release mechanism. When the supporting mechanism is installed on the tube release mechanism, the tube release mechanism will discharge the telescopic tube. When the telescopic tube is not in use, the telescopic tube is limited by the tube release mechanism and cannot be extended.

[0016] (2) The water-conducting cotton can absorb the water droplets on the outer wall of the condenser tube, and the water droplets will be gathered into a water flow and enter the interior of the drain groove. Since the bottom of the drain groove is inclined, the water entering the drain groove enters the interior of the drain hole from the drain pipe. The water will flow from the inside of the drain hole through the interior of the fan and take away the heat inside the fan; thereby achieving the goal of draining water while taking away the heat inside the fan.

[0017] (3) When the wind blows, the support rope stabilizes the telescopic tube; when the worm is not rotating, the worm wheel does not rotate, and the worm wheel and the worm are self-locking. When the worm wheel does not rotate, the worm will not rotate, so that the support rope will not move. The length of the telescopic tube after extension is limited, so that the telescopic tube is stabilized.

[0018] (3) The threaded rod is installed inside the threaded hole by means of a telescopic rod. Before the threaded rod enters the threaded hole, the clamping joint is aligned with the inside of the clamping hole. Both the clamping joint and the clamping hole are polygonal structures. When the threaded rod is rotated, the threaded rod rotates inside the threaded hole. When the threaded rod rotates inside the threaded hole, the clamping hole is driven to rotate by the clamping joint. The rotation of the clamping hole drives the worm to rotate. The rotation of the worm synchronously drives the worm wheels on both sides to rotate.

[0019] (4) When the telescopic tube is extended, the support rod arranged on the telescopic tube moves, and the support rod drives the slip ring to move synchronously. The slip ring moves and slides on the support rope. After the telescopic tube is extended, it can be connected to the support rope by the slip ring. The support rope is arranged on both sides of the telescopic tube. Since one end of the support rope is fixed on the wire drum, the wire drum is self-locked by the worm gear and cannot rotate, so that one end of the support rope is fixed and the other end of the support rope is locked by the locking rod. When the locking rod is locked, the support rope is fixed at the same time, so that the installation process is simple, and when disassembling, only the pull rod needs to be pulled. The pull rod moves to unlock the telescopic tube from the inside of the socket. At the same time, the wire rope is unlocked, which improves the disassembly efficiency when the air conditioner needs to be disassembled. BRIEF DESCRIPTION OF THE DRAWINGS

When the threaded rod 52 rotates inside the threaded hole 54, the clamping hole 55 is driven to rotate by the clamping joint 53, and the rotation of the clamping hole 55 drives the worm 3 3 rotates, the worm 33 rotates synchronously to drive the worm wheels 37 on both sides to rotate; the worm wheel 37 rotates to drive the connecting shaft 36 to rotate, the connecting shaft 36 rotates to drive the driven wheel 38 to rotate synchronously, the driven wheel 38 rotates to drive the latch 39 to rotate synchronously, the latch 39 and the driven wheel 38 rotate synchronously, the latch 39 drives the wire drum 34 to rotate synchronously, a support rope 65 is wound around the wire drum 34, and the support rope 65 is arranged on both sides of the telescopic tube 4. Since one end of the support rope 65 is fixed on the wire drum 34, the wire drum 34 is self-locked by the worm wheel 37 and the worm 33 and cannot rotate, so that one end of the support rope 65 is fixed, and the other end of the support rope 65 is locked by the locking rod 61 When the locking rod 61 locks the support rope 65, the end of the telescopic tube 4 is fixed at the same time; when the locking rod 61 is inserted into the inside of the insertion hole 69, the end of the locking rod 61 is an inclined surface, and the locking rod 61 will first contact the abutment 613, and the abutment 613 will first compress the elastic member 614, and the elastic member 614 is received in the inside of the through groove. When the abutment 613 slides to the relative position of the locking hole 62, the elastic member 614 is reset, and the elastic member 614 pushes the abutment 613 into the inside of the locking hole 62. Since the locking hole 62 and the abutment 613 are locked, the locked locking rod 61 and the pull rod 68 are fixed, and the locking rod 61 It will not detach from the pull rod 68, therefore, the support rope 65 arranged on the locking rod 61 is tightened; when the locking rod 61 enters the inside of the insertion hole 69, it squeezes the abutment head 613 and drives the squeezing block 63 to squeeze the side wall of the sealing ring 615.
