Description

1306136 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a telescopic device, and more particularly to a combined tubular expansion device. [Prior Art]

~There are both expansion tubes with adjustable lengths and control units for controlling the combination of telescopic extensions. They are mostly used for racks such as music stands and instrument stands. These brackets need to be adjusted to match the user's body or habits. ^ The telescopic device is required to adjust its length by adjusting its combination tube. For example, U.S. Patent No. 6,698,698 B1 discloses a telescopic device, which is a combined tube telescopic device having an adjustable length. The combination tube has a group of j: a sliding tube body 'and a portion disposed between the tube body; a shrinking control: the opening member can open the telescopic control member to allow the tubes to slide relative to adjust the The length of the tube is combined and the relative position of the tube can be fixed by locking the telescopic device to maintain the adjusted length of the tube. / However, as described in the prior patent documents, the telescopic device can adjust the length of the combined tube. However, it is composed of many parts and has a complicated structure, which is not only difficult to manufacture, but also reduces the yield of the product and promotes the ancient product. Cost, in use, it is also necessary to hold the tube with one hand. One piece of hand-operated telescopic control can be used to stably operate the telescopic control element, so that it is also extremely inconvenient. [Content of the invention] 4

^06136 provides a disadvantage of the above-mentioned existing telescopic device, and the object of the present invention is a telescopic device which is simple in construction and easy to use. The technical means adopted by the present invention is to include the control element and a combined tube body; wherein: the control element comprises: -, -, s" The shape has a cavity formed therein, and has an inverted sleeve: a working chamber and an outer sliding hole, and a direction of the door-opening direction formed in the direction of the sliding rail hole is perpendicular to the sliding rail hole and the sleeve a hole opening and a sweating port, and a fixing member formed on the inner wall of the brake seat with respect to the front opening; wherein the 槐 ' is inserted from the brake opening to the brake seat and has a communication a sleeve hole connecting the rail hole and the sleeve hole, a fixing hole of the brake seat member, an elastic member mounted between the fixed element: and the at least - formed at a latch on the inner wall of the hole and located on the same side as the aforementioned fixing hole; the combined tube includes: a "moon rail g body" having an outer diameter smaller than a sleeve hole of the brake block; the slide tube outer tube band, VL ± - π, J is axially concave with a slide rail, and the slide rail is formed with a group The pin holes arranged in the sliding rails, each pin hole is matched with the plug of the block; _ the fitting pipe body is connected to the sleeve hole of the brake seat, and the inner diameter thereof is matched with the outer side of the slide rail body path. When the telescopic device is used in August, the brake block is inserted into the brake seat, and the slide pipe body is sequentially passed through the slide rail hole of the brake seat, the brake 5 1306136

a sleeve hole of the block, a sleeve hole of the brake seat, the sleeve body, and the slide rail body is slid to a proper position; the fixing element and the brake element are mounted on the brake seat Between the fixed holes of the block, the brake block is pushed by the elastic force of the elastic member, so that the brake block moves away from the brake opening of the brake seat, but since the sleeve of the brake block is a slippery body So that the brake block cannot be disengaged from the brake opening, and forms a slightly convex (four) opening; at this time, as the brake block moves, the latch of the brake block is inserted into the pin hole of the slide rail body, thereby Fixing the position of the rail body so that it cannot slide back and forth between the rail hole, the sleeve hole, the sleeve hole, and the sleeve body; - when the length needs to slide the slide tube body, Then, the force is applied against the elastic force of the elastic 7G member, and the portion of the brake block protruding from the brake opening is pressed back into the brake seat. 'The pin of the brake block is separated from the pin hole of the sliding pipe body to allow the sliding pipe body to slide. To adjust the length. After the length adjustment is completed, the force is stopped, and the elastic force of the 7G piece causes the brake block to move again toward the direction of the brake seat, and the state of the micro-bumping brake opening is again formed. The latch is also inserted into the lock hole of the slide rail body. The position of the rail body is again fixed to maintain the adjusted length. 2 It can be understood that the specific construction and use method of the present invention can achieve the purpose of adjusting the length by pressing in or releasing the brake pad's, which can be conveniently facilitated by one hand, and can be facilitated by ~k J to early. „. ^ Μ疋Operation; and its structure is made up of a few parts that are easy to manufacture, so the telescopic device used for this purpose.
