The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.

Referring to fig. 1-3, a suction cup type tool-free installation telescopic rod comprises an outer tube 1, an inner tube 2, a first fixed seat 3, a second fixed seat 4, a suction cup 5, a connecting part 6 fixedly connected with the suction cup 5, and a locking device 9 for locking the outer tube 1 and the inner tube 2;

the inner pipe 2 is partially sleeved in the outer pipe 1 to realize the extension and contraction of the telescopic rod;

the other end of outer tube 1 inserts in first fixing base 3, the other end of inner tube 2 with 4 thread connections of second fixing base, the outer terminal surface of first fixing base 3 and second fixing base 4 all is equipped with connecting portion 6 and sucking disc 5, and respectively with connecting portion 6 rotates and is connected.

Specifically, the telescopic rod has the advantages that the outer tube 1, the inner tube 2, the first fixing seat 3, the second fixing seat 4, the sucker 5 and the locking device 9 are matched with one another, so that the mounting is facilitated, and the supporting force of the telescopic rod is increased; firstly, adsorb the sucking disc 5 at telescopic link both ends and be fixed in on the wall, adjust the use length of outer tube 1 and inner tube 2 cup joint the position with the adjustment telescopic link simultaneously, the telescopic link can rely on the suction of sucking disc 5 to prop on the wall this moment, rethread locking device 9 is with the connection locking of outer tube 1 and inner tube 2, because the other end and the 4 thread connections of second fixing base of inner tube 2, the direction of keeping away from inner tube 2 is rotated second fixing base 4 and can be increased telescopic link length, and then unnecessary air in the extrusion sucking disc 5, thereby increase sucking disc 5's suction increases the holding power that the telescopic link propped in the wall, and the preceding terminal surface and the 6 rotatable coupling of connecting portion of second fixing base 4, when rotating second fixing base 4, sucking disc 5 still can adsorb tightly on the wall, can not rotate along with the rotation of second fixing base 4, can be convenient for installation.

Further, the outer ring of one end of the connecting portion 6, which is far away from the suction cup 5, is provided with a first annular groove 62, and the outer end faces of the first fixing seat 3 and the second fixing seat 4 are provided with first annular bosses matched with the first annular groove. Connecting portion 6 is close to the outer lane of 5 one ends of sucking disc is equipped with the annular boss 61 of second, sucking disc 5 be equipped with the annular recess of the annular boss 61 assorted second of second. Specifically, connecting portion 6 and first fixing base and second fixing base can realize joint and rotatable coupling through first annular groove and first cyclic annular boss.

In this embodiment, the pipe orifice of the inner pipe 2 close to the second fixing seat 4 is fixedly connected with a screw rod 7, inner threads matched with the screw rod 7 are arranged in the second fixing seat 4, and the inner pipe 2 is installed on the second fixing seat 4 through the screw rod 7. Specifically, the thread rod 7 and the inner tube 2 are connected by threads, and the total length of the whole telescopic rod can be adjusted by adjusting the depth of the thread rod 7 screwed into the second fixed seat 4. Wherein, when installing the telescopic link on the wall, through constantly rotatory second fixing base 4 so that the screw thread of screw thread pole 7 during second fixing base 4 is unscrewed, can strengthen the both ends of telescopic link and compress tightly the pressure on the wall respectively to make the telescopic link fix on the wall more steadily.

In this embodiment, a slider 8 for pulling up the suction cup 5 is provided at the edge of the suction cup 5. Specifically, when the slider 8 at the edge of the suction cup 5 is pulled up, air enters the suction cup 5, so that the suction cup 5 can be pulled up conveniently.

Preferably, the suction cup 5 and the connecting portion 6 are of an integrally formed structure, the suction cup 5 is made of a soft material, and the connecting portion 6 is made of a hard material. Specifically, need not additionally to install sucking disc 5 and connecting portion 6, convenient and fast, sucking disc 5 generally is soft material in addition, can't directly be connected with first fixing base 3 and second fixing base 4, also plays important connection effect for connecting portion 6 of hard material, makes sucking disc 5 more stable and inseparable with being connected of first fixing base 3 and second fixing base 4.

In this embodiment, a collar 12 for preventing the inner tube 2 from directly dropping out of the outer tube 1 is installed at the position of the outer tube 1 far away from the orifice of the first fixing seat 3. Specifically, because inner tube 2 cup joints in outer tube 1, when the telescopic link needs to be extended, the length of taking inner tube 2 out is long and inner tube 2 is easily taken out of outer tube 1, and therefore the pipe orifice of first fixing base 3 is kept away from at outer tube 1 and set up lantern ring 12 and can avoid this kind of condition.

The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
