It is used for a 1G fixed object such as a table board, barbecue grill, or drips, etc. to support it and adjust the height of the object 10 ', and it includes a fixed hollow sleeve. A lifting rod 12 penetratingly disposed therein with a mounting object fixed at the top end, and a set screw 13 penetrating radially through the sleeve u to lock the lifting rod 12. By controlling the lifting displacement amount and fixing of the lifting rod 12, Lock the position to achieve the purpose of adjusting the height of the mounting object 10. When the Ge 4 kills the object 10 and there is an item on the stand and you want to lower the tripod 1 to produce a high yield, the weight 12 will increase due to the increased mass and the lifting rod 12 will be fast; In addition, if force is applied to prevent a sudden drop, the mounting object 10 or its upper surface may be overturned, and damage may be caused. Therefore, you need to support the mounting surface 2 with one hand or ask others to help support and then loosen the positioning screw 13 To adjust the height of the work, it can be known that the general stand 1 uses the simple displacement positioning between the sleeve U and the lifting f 12 to achieve the height adjustment function. Niu Gan K is used because of abuse. Precautionary precautions Inconvenience. [New content] Therefore, the purpose of this new model is to provide a «King ~ Mirror pressure ， air pressure, and to achieve a buffering descent effect of the air pressure drop foot stand. II 20 M249561 Therefore, this new type of air pressure drop The tripod includes a base corresponding to the sleeve and a lifting rod. The base includes-an upright hollow sleeve with a closed bottom end. The lifting rod includes-is longer and thinner than the sleeve and can be opposite to the bottom end of the sleeve An upright rod body penetrating up and down in the sleeve and having a horizontal bottom wall, and a flexible pad fixed on the bottom wall and having an outer diameter not less than that of the sleeve, and the peripheral edge of the sleeve completely contacting the inner wall of the sleeve during the downward movement The function of the new 1 is to provide a pneumatic slow down footrest that has a lowering speed buffer of 10 for its lifting rod and the stability, safety and convenience of using the South. [Embodiment] ^ The aforementioned and other technologies related to the new model The content, characteristics and effects will be clearly understood in the following detailed description of a preferred embodiment with reference to the drawings. Θ 15 Referring to FIG. 2 and FIG. _Such as 2G fixed items such as tabletop barbecue grills or drips are fixed on it to support and adjust the height of the mounted objects 20, and include-including-the base of the cylindrical upright hollow sleeve 31 closed at the bottom end, can be opposite The sleeve 3 is inserted through it in a vertical displacement: and the lifting rod 4 of the mounting object 20 is fixed at the top, and a positioning screw $ penetrating through the sleeve 31 to lock the lifting rod 4 is fixed. The sleeve 31 can achieve the goal of stable standing by a disc-shaped chassis 32 as shown in FIG. 2 or most of the retractable umbrella bones that extend in the shape of an umbrella and have a seal for a fixed covering on the bottom of the lifting rod. 4 Includes a long, hollow rod body 41, 20 which is longer than the sleeve 31, and has a circular horizontal bottom wall 411. The bottom surface of the wall 41 and the outer diameter of the wall 41 is slightly larger than the sleeve 3a. The protrusion is provided near the bottom end of the rod body 41 and is used to prevent the rod body 4 from being separated from the limit position of the sleeve 31 when being pulled out on the moon # 43. In this embodiment, the flexible pad body 42 is a leather pad. ° As shown in FIG. 3, the bottom wall 4m of the rod body 41 of the lifting rod 4 and the inner soil of the sleeve are in the same circle, and change with the displacement of the rod body 4 丨. The gap between the bottom wall 411 and the sleeve 31 is covered by a flexible cushion body 42 that is large and fully contacts the inner wall of the sleeve 31. ίο 15 During the downward movement of the lifting rod 4 relative to the base 3, on the one hand, the downward force is cushioned by the friction between the flexible body 42 and the sleeve 31, and more importantly, the flexibility of the flexible cushion body 42 is used. Flexible characteristics, so that the gas to be discharged due to the reduction in volume and high pressure within 3g of the compression space can be slowly leaked out by the flexible cushion body 42 covering the gap between the bottom wall 411 and the sleeve 31, and the compression space 2 〇The volume gradually decreases and the air dust # keeps the balance to achieve the purpose of ascending rotation * stable and slowly decreasing. π
口此田奴凋整架置物20尚度而旋開該定位螺絲5時 、，藉由該撓性塾體42使受壓而下降之升降桿4穩定緩降， 減低架置物10上物品翻覆掉落之意外。At this time, when the set screw 20 is still open and the set screw 5 is unscrewed, the lifting rod 4 lowered under pressure by the flexible carcass 42 is lowered steadily and slowly, and the items on the set 10 are turned over and over. Falling accident.
20 歸納上述，本新型氣壓緩降腳架是利用撓性墊體42, 使壓縮空間2G緩和且穩定地排出空氣，因此具有使用安全 及提鬲便利性的功效，確實可達到本新型之目的。【圖式簡單說明】 圖1是習知腳架在使用狀態之立體圖； 圖2是本新型氣壓緩降腳架之較佳實施例與一組裝其 6 M249561 上之架置物的立體分解圖；及 圖3是該實施例之侧剖面視圖。 M249561 【圖式之主要元件代表符號說明】 2 腳架 4 升降桿 20 架置物 41 桿本體 3 基座 411 底壁 30 壓縮空間 42 撓性墊體 31 套筒 43 限位件 32 底盤 5 定位螺絲20 In summary, the new type of air pressure drop foot stand uses the flexible cushion body 42 to gently and stably discharge the air in the compressed space 2G. Therefore, it has the functions of safety and convenience, and can indeed achieve the purpose of the new model.
