Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, a length-adjustable metal rod structure, including outer pole 1 and interior pole 2, interior pole 2 slides and inserts the inside of establishing at outer pole 1, the bottom of outer pole 1 rotates and inserts and is equipped with screw rod 4, screw rod 4 is located the outside port fixed mounting of outer pole 1 has the handle 5 that changes, screw rod 4 screw thread inserts the inside of establishing at interior pole 2, the position of keeping away from handle 5 on the surface of outer pole 1 is provided with and is used for further spacing limiting mechanism to interior pole 2, in the use through the regulation realization to between interior pole 2 and the outer pole 1 metal rod length, when needing to adjust interior pole 2 from the inside of outer pole 1, directly utilize handle 5 to rotate screw rod 4, utilize the rotation of screw rod 4 to drive interior pole 2 and slide in the inside of outer pole 1, thereby change the mode that the tradition utilized interior pole 2 of manual pulling into the mode that now moves through the screw rod 4 drive, play the effect of economizing on, even under the condition that rust appears because of permanent use between interior pole 2 and outer pole 1 or dust infiltration, also save the mode that the tradition utilized interior pole 2 of manual pulling, make the operation convenient, make the operation more convenient, thereby the interior pole 2 outside is restricted when the screw rod 2 and the mechanism appears, thereby the long-time limit the long-term use, the screw rod is damaged, the condition appears, thereby the screw rod 4 mechanism appears, the long-time use of utilizing the screw rod, thereby the screw rod is damaged, the condition of the outside can be avoided.

Further, limiting mechanism includes spacing 10, spacing 10 is "U" shape structure, two arms of spacing 10 slide and insert the inside of establishing in outer pole 1, the jack 7 with two arm size looks adaptations of spacing 10 is evenly seted up to the lateral wall of interior pole 2, limiting mechanism in use, in the time of pole 2 in needs removal, outwards stimulate spacing 10, make two arms of spacing 10 break away from the jack 7 on interior pole 2 surface, alright remove interior pole 2 this moment, in the time of pole 2 in need not removing, insert interior pole 2 and outer pole 1 in the jack 7 of pole 2 with two arms of spacing 10.

Further, two arms of spacing 10 all overlap and are equipped with spring 12, spring 12's both ends respectively with outer pole 1 and spacing 10 fixed connection, two arms of spacing 10 still overlap and are equipped with spring 12, make spacing 10 receive spring 12's pulling force all the time, can not make spacing 10 break away from outer pole 1, stability when reinforcing spacing 10 is spacing.

Further, the surface of spacing 10 is rotated and is connected with bull stick 11, recess 9 has been seted up for the position of bull stick 11 in the surface of outer pole 1, when pole 2 in the needs removal, need draw out spacing 10, and spacing 10 receives the pulling force of spring 12 again, thereby make spacing 10 need be held with the hand all the time, otherwise spacing 10 will restrict the removal of pole 2 in will, can utilize bull stick 11 and recess 9 block each other after spacing 10 draws out this moment, make spacing 10 can not retract inside, thereby need not always operate with holding spacing 10 with the hand.

Further, two spouts 6 have been seted up on interior pole 2's surface, and the inner wall fixed mounting of outer pole 1 has two spacing nose bars 8, and interior pole 2 passes through spacing nose bar 8 and spout 6 and outer pole 1 sliding connection, stability when 2 slided in the reinforcing.

Further, the top end of the outer rod 1 is fixedly provided with a sealing gasket 3, the sealing gasket 3 is sleeved outside the inner rod 2, and the sealing gasket 3 arranged at the port of the outer rod 1 can reduce the dust entering the inner part of the outer rod 1.

In conclusion, the length of the metal rod is adjusted by adjusting the inner rod 2 and the outer rod 1 in use, when the inner rod 2 needs to be adjusted from the inside of the outer rod 1, the rotating handle 5 is directly utilized to rotate the screw rod 4, the rotation of the screw rod 4 is utilized to drive the inner rod 2 to slide in the outside rod 1, so that the traditional mode of manually pulling the inner rod 2 is changed into the mode of moving through the driving of the screw rod 4, the effect of saving labor is achieved, even if rust or dust infiltration occurs between the inner rod 2 and the outer rod 1 due to long-term use, the labor is saved compared with the traditional mode of directly manually pulling the inner rod 2, the operation is more convenient, after the inner rod 2 is moved outwards to a proper distance, the limiting mechanism is utilized to limit the inner rod 2 and the outer rod 1, and the situation that the screw rod 4 is stressed for a long time in use to cause damage to the thread of the screw rod 4 is avoided, when the limiting mechanism is used, when the inner rod 2 needs to be moved, the limiting frame 10 is pulled outwards, two arms of the limiting frame 10 are separated from the jack 7 on the surface of the inner rod 2, the inner rod 2 can be moved at the moment, when the inner rod 2 does not need to be moved, the two arms of the limiting frame 10 are inserted into the jack 7 of the inner rod 2 to fix the inner rod 2 and the outer rod 1, the two arms of the limiting frame 10 are also sleeved with springs 12, the limiting frame 10 is always pulled by the springs 12, the limiting frame 10 cannot be separated from the outer rod 1, the stability of the limiting frame 10 during limiting is enhanced, when the inner rod 2 needs to be moved, the limiting frame 10 needs to be drawn out, the limiting frame 10 is pulled by the springs 12, the limiting frame 10 needs to be held by hands all the time, otherwise, the limiting frame 10 can limit the movement of the inner rod 2, at the moment, the rotating rod 11 can be clamped with the groove 9 after the limiting frame 10 is drawn out, the limiting frame 10 can not retract into the inner part, so that the limiting frame 10 does not need to be held by hands all the time for operation, and the sealing gasket 3 arranged at the port of the outer rod 1 can reduce the condition that dust enters the inner part of the outer rod 1.

The foregoing shows and describes the basic principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention.
