Detailed Description
The following examples are given in conjunction with the accompanying drawings to further illustrate the embodiments of the present invention. The present invention is not limited to the description of the following embodiments.
Example 1
As shown in the figure: the embodiment discloses an integrative telescopic link of extension locking, it need not additionally to be equipped with the connecting piece can be fast convenient be fixed in between two supporter, the structure is succinct, the dependable performance.
Specifically, the method comprises the following steps: the device comprises an outer loop bar 1, an extension bar 2, a gradual change screw rod 4 and a locking and positioning nut 5. Further, the diameter of the outer loop bar 1 is larger than the diameter of the extension bar 2.
Furthermore, one end of the extension rod 2 is inserted into the outer loop bar 1, and the gradual change screw rod 4 is fixedly connected with one end of the extension rod 2, which is positioned in the outer loop bar 1; the diameter of the gradual-change screw rod 4 is gradually increased from the end close to the extension rod 2 to the end far away from the extension rod 2.
Furthermore, a locking and positioning nut 5 is connected with the gradual change screw rod 4, and an expansion joint 6 is arranged on the side wall of the locking and positioning nut 5; in the positioning process of the telescopic rod, the locking and positioning nut 5 moves along the length direction of the gradual change screw rod 4.
In the following, an application mode of this embodiment is exemplified, in a working process (i.e. in a positioning process of the telescopic rod), first, two ends of the telescopic rod, that is, an end portion of the outer sleeve rod 1 and an end portion of the extension rod 2 are respectively abutted against side walls of two supports (taking two opposite walls as an example), after the length of the telescopic rod is determined, the extension rod 2 is rotated, at this time, the gradually-changed screw rod 4 rotates along with the rotation of the outer sleeve rod, the locking and positioning nut 5 moves towards a large-diameter end of the gradually-changed screw rod 4 under the pushing of the threads of the gradually-changed screw rod 4 and the locking and positioning nut 5, in this process, the locking and positioning nut 5 expands outwards (expansion joint 6) under the extrusion of the gradually-changed screw rod 4, and the locking and positioning nut 5. During unlocking, the extension rod 2 is rotated reversely, the locking positioning nut 5 moves reversely, and the action principle of the locking positioning nut is opposite to that of positioning locking.
Preferably, the base 3 is arranged at the end of the outer loop bar 1, which abuts against the support, and the base 3 is arranged at the end of the extension bar 2, which abuts against the support. Base 3 supports with the support and leans on, improves the frictional force between support and telescopic link on the one hand, and on the other hand prevents that the telescopic link from rocking. Further, in some embodiments of the present invention, an anti-slip rubber pad is fixedly disposed on the surface of the base 3 connected to the support.
Preferably, an idling section 8 is fixedly arranged at the small-diameter end of the gradual-change screw rod 4, the diameter of the idling section 8 is smaller than the inner diameter of the locking and positioning nut 5, when the telescopic rod is unlocked, the locking and positioning nut 5 moves to the idling section 8, the extension rod 2 continues to rotate, and the locking and positioning nut 5 is not forced to move towards the end part of the extension rod 2 any more. In the unblock in-process promptly, the opposite direction of rotation extension rod 2 (opposite with locking process direction of rotation), when locking set nut 5 moved the path end portion of gradual change screw rod 4, because of whole nut is located overcoat pole 1 inside, can't discern its position, generally whether can shrink to judge whether the unblock through constantly trying extension rod 2, if the rotation cycle overlength, locking set nut 5 top is leaned on behind extension rod 2 tip, if continue to rotate, can take place the card pause easily, if hard too violently cause the screw thread impaired easily, long-time repetition has certain influence to the life of whole telescopic link. This idle rotation section 8 can avoid this kind of phenomenon to take place, and after locking set nut 5 reachd the 4 small diameter ends of gradual change screw rod, continue to rotate, this locking set nut 5 gets into idle rotation section 8, because of the diameter of idle rotation section 8 is less than locking set nut 5's internal diameter (screw), continues to rotate locking set nut 5 and no longer removes to the tip direction of extension rod 2, can not take place the extrusion with the 2 tip of extension rod. When locking is required, the locking positioning nut 5 returns to the gradual change screw rod 4 by forward rotation. Further, the length h1 of the idle section 8 is equal to the length h2 of the lock positioning nut 5.
Preferably, the idling section 8 is fixedly connected with a baffle plate 9, the baffle plate 9 is fixedly connected with the connecting section 7, and the idling section 8 and the connecting section 7 are respectively positioned at two sides of the baffle plate 9; the connecting section 7 is fixedly connected with the end part of the extension rod 2, and the blocking piece 9 is used for blocking the locking and positioning nut 5 from contacting with the end part of the extension rod 2. Furthermore, one end of the extension rod 2 is inserted into the connecting section 7. Further, the locking and positioning nut 5 is made of an ABS material.
Preferably, the outer wall of the locking and positioning nut 5 is fixedly provided with an anti-slip structure for preventing the locking and positioning nut 5 from rotating per se in the locking and positioning process (i.e. preventing the locking and positioning nut 5 from rotating along with the extension rod 2). Further, the anti-slip structure is a groove anti-slip structure (anti-slip groove) or an anti-slip point.
Preferably, the extension rod 2 and the outer loop bar 1 are rotatable relative to their respective bases 3.
Preferably, the base 3 includes a seat plate 10 and a shaft rod 11, a shaft hole 12 for connecting the shaft rod 11 is provided in the middle of the seat plate 10, one end of the shaft rod 11 is fixedly connected to the corresponding extension rod 2 or the outer sleeve rod 1, a circular protrusion 13 is provided on the periphery of the shaft rod 11, a groove corresponding to the circular protrusion 13 is provided on the inner side of the shaft hole 12, and when the shaft rod 11 is connected to the shaft hole 12, the circular protrusion 13 is clamped in the groove.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
