Detailed Description

To further clarify the objects, advantages and features of the present invention, a non-perforated height-adjustable cane according to the present invention will be described in more detail with reference to the accompanying drawing 1~4. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.

As used in this specification, the singular forms "a", "an" and "the" include plural referents, and the plural forms "a plurality" includes more than two referents unless the content clearly dictates otherwise. As used in this specification, the term "or" is generally employed in its sense including "and/or" unless the content clearly dictates otherwise, and the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either fixedly connected, detachably connected, or integrally connected. Either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The utility model provides a no cellular type altitude mixture control stick, as shown in fig. 1, be vertical shaft-like, the upper end is for including the handle portion 1 that supplies the user hand to grip, and the lower tip is for supporting at the support part 6 of ground isoplanar, and the intermediate part is the connecting rod portion 2 of connecting handle portion 1 and support part 6. The link portion 2 includes a hollow outer cylinder 3 and an inner cylinder 5, wherein the outer cylinder 3 has a diameter larger than that of the inner cylinder 5, and the outer cylinder 3 is located above the inner cylinder 5 at a position close to the handle portion 1. This embodiment preferably uses the handle portion 1 made of plastic material to facilitate the structural design therein, and the connecting rod portion made of metal material to improve the stability of the support. Against this background, the outer cylinder 3 is connected to the handle 1 by interference fit.

A screw 7 is coaxially arranged in the outer cylinder 3, one end of the screw 7 is fixed on the connecting rod part 2, and the end part of the other end is provided with a stop nut 10. The handle 1 of the present invention includes a tubular portion extending from the holding portion toward the outer cylinder, not only a portion to be held by a single finger. As shown in fig. 3, the screw 7 is fixed on the cylindrical extension of the handle 3 by a screw locking device 12, and it is known to those skilled in the art that the screw may also be fixed on the outer cylinder in this embodiment, all of which fall within the protection scope of the present application.

As shown in fig. 2, the screw 7 is located inside the outer cylinder 3 and has a length not greater than the length of the outer cylinder 3. A stop nut 10 fixedly arranged at the other end of the screw rod 7 is also positioned inside the outer cylinder 3.

The inner end part of the inner cylinder 5, which is close to the outer cylinder 3, is internally and fixedly provided with a thread sliding block 8, specifically, the middle part of the thread sliding block 8 is fixed in the inner cylinder 5 through at least one locking screw 9, and the two are fixedly connected and can keep synchronous motion. The threaded slider 8 and the screw 7 can move in a matched manner, namely the screw 7 is fixed, and the threaded slider 8 can rotate on the threaded slider to drive the inner cylinder to rotate and move up and down at the same time. Meanwhile, the stop nut 10 is arranged at the fixed lower end of the upper end of the screw 7, so that the moving stroke of the threaded sliding block 8 is limited, and the threaded sliding block 8 is ensured to further move towards the direction far away from the screw 7 so as to be separated from the screw 7.

The joint of the outer cylinder 3 and the inner cylinder 5 is provided with a locking ring 4 capable of rotating relatively, the locking ring 4 is sleeved outside the outer cylinder 3, in the embodiment, preferably, threads are arranged on the outer side of the outer cylinder, threads are arranged on the inner side of the locking ring, and the threads on the inner side of the locking ring are matched with the threads on the outer side of the outer cylinder to realize relative rotation.

The locking ring 4 is provided with a locking ring 11 therein, as shown in fig. 4. The locking ring 11 is step-shaped, that is, comprises an upper locking ring part and a lower locking ring part, and a gap penetrating through the upper locking ring part and the lower locking ring part is arranged in the circumferential direction. The upper part of the locking ring 11 can be inserted into a gap between the inner cylinder and the outer cylinder, the inner wall of the outer cylinder can extrude the upper part of the locking ring 11, and the notch on the locking ring 11 can be tightened up, so that the inner cylinder is locked in a limiting way. Therefore, the thickness of the upper part of the locking ring is set to be more than or equal to the radial distance between the outer cylinder and the inner cylinder, so that the upper part of the locking ring is better matched with the inner cylinder and the outer cylinder. And the difference of the outer diameters of the upper part and the lower part of the locking ring is larger than or equal to the wall thickness of the matching part of the outer cylinder and the locking ring, so that when the locking ring 4 rotates towards the locking direction, the wall of the outer cylinder can abut against the shoulder part of the locking ring 11, and further rotation movement of the locking ring 4 is limited.

When the screw thread sliding block is used, the locking ring is loosened downwards, the locking ring in the locking ring is loosened, the inner barrel is rotated at the moment, the inner barrel drives the screw thread sliding block to rotate together, and the screw thread sliding block can move up and down along the screw rod through left rotation or right rotation, so that the relative position between the inner barrel and the outer barrel is adjusted, and the height is adjusted; when the locking ring is locked upwards, the upper part of the locking ring is inserted into a gap between the inner cylinder and the outer cylinder, and the inner locking ring deforms elastically to clamp the outer cylinder and the inner cylinder, so that the up-and-down movement of the inner cylinder is limited.

Therefore, the utility model provides a pair of cellular type altitude mixture control stick, convenient height-adjusting, and the bearing is stable, durable reliable, succinct pleasing to the eye.

The disclosed embodiments are not limited to the embodiments shown herein. Any modification, equivalent replacement, improvement and the like made by the utility model shall belong to the protection scope of the utility model.
