Description

Technical Field

[0001] The utility model relates to a support rod connection structure of a floor fan, in particular to a support rod locking structure of a floor fan. Background Art

[0002] Floor fans have the characteristics of large air volume and low noise. They are very effective in indoor ventilation, heatstroke prevention and cooling in the hot summer, and are widely used in warehouses, workshops, homes and other places. Floor fans can be placed on the ground for safe use, but they occupy a large area of ​​the ground and are difficult to adapt to various height requirements. Therefore, in order to adjust the height of the floor fan, a telescopic rod structure is designed inside the support rod of the floor fan. The commonly used method at present is to use a two-section rod connection structure as the support rod of the floor fan, and the two rods are rigidly locked with a locking screw, that is, the locking screw directly passes through the outer rod and presses against the inner rod to lock it. The rod body is relatively thin and is easily deformed after being rigidly pressed by the locking screw, which destroys the integrity of the support rod, reduces its strength, and shortens the service life of the floor fan.

[0017] The present invention is further described below in conjunction with the accompanying drawings. A floor fan support rod locking structure includes an upper rod 1 and a lower rod 2, the upper rod 1 and the lower rod 2 being connected as a whole via a locking structure 3, the locking structure 3 including a sleeve 31 encircling the upper rod 1 and a locking sleeve 32 clamped at the end of the lower rod 2, the sleeve 31 covering the locking sleeve 32 therein, the upper rod 1 being inserted into the sleeve 31 and the locking sleeve 32 in sequence from top to bottom and connected to the lower rod 2; a pressing plate 4 is embedded in the outer cylindrical surface of the locking sleeve 32, a locking hole 5 is provided through the sleeve 31 and the lower rod 2, a locking rod 6 passes through the locking hole 5 and presses against the pressing plate 4, forcing the locking sleeve 32 to adhere to the cylindrical surface of the upper rod 1, thereby locking the relative position between the upper rod 1 and the lower rod 2.

[0018] The end of the locking sleeve 32 protrudes from the body to form a clamping platform 321 , and the clamping platform 321 is clamped at the end of the lower rod 2 .

[0019] The outer cylindrical surface of the locking sleeve 32 is provided with a slot, and the pressing piece 4 is embedded in the slot.

[0020] The outer cylindrical surface of the locking sleeve 32 is provided with a plurality of raised reinforcing ribs 322 .

[0021] The locking sleeve 32 , the clamping platform 321 and the reinforcing rib 322 are integrally injection-molded from a plastic material.

[0022] The sleeve 31 and the pressing piece 4 are made of metal.

[0023] A nut 8 is welded to the sleeve 31 at a position corresponding to the locking hole 5 , and the locking rod 6 is screwed into the nut 8 .

[0024] The outer end of the locking rod 6 is connected to a hand wheel 7 .

[0025] Working principle: The upper rod and the lower rod are connected as a whole through a locking structure. The locking structure includes a sleeve that traps the upper rod inside it and a locking sleeve that is clamped at the end of the lower rod. When the upper rod and the lower rod are docked, the sleeve first covers the locking sleeve inside it, and the upper rod is inserted into the sleeve and the locking sleeve from top to bottom in sequence until it moves and retracts to the height required by the user.

[0026] At this time, in order to protect the integrity of the rod body, a pressure plate is embedded in the position of the locking hole of the locking sleeve corresponding to the locking hole. The locking rod passes through the locking hole of the sleeve and the locking hole of the lower rod in turn, and presses against the pressure plate, abandoning the traditional way of direct contact between the locking rod and the rod body, avoiding excessive force on the local cylindrical surface of the upper rod, significantly reducing the risk of dents, deformation or even damage to the upper rod, and effectively extending the service life of the support rod.

[0027] Furthermore, a pressure plate is used for intermediate transition, and the pressure plate is compressed, forcing the locking sleeve to be tightly connected to the outer cylindrical surface of the upper rod, effectively enhancing the connection strength. Even when the height of the floor fan is frequently adjusted, the support rod can be kept tight, avoiding the loosening problem caused by multiple loosening and tightening operations in the traditional structure, and improving the overall stability of the floor fan.

[0028] Furthermore, a handwheel is connected to the end of the locking rod. When the user needs to adjust the height, he or she can operate the handwheel, making the adjustment process more convenient without the need for additional tools, reducing the difficulty of operation and improving user comfort.

[0029] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
