New Description·· 【New Technical Fields】...The telescopic sleeve positioning auxiliary structure of the folding tripod in this case is matched with various types of forced pressure locking devices originally installed on the outer casing g. Before the tube is tightened, the elastically inserted (four) inner sleeve can be used to preset the upper and lower closing bolt holes to carry out the segmented pre-clamping positioning--and thus effectively prevent the inner sleeve from suddenly losing its binding force. Dangerous situations such as falling down, impacting, etc., which often occur. Click [Previous Technology] Press, the folding tripod is usually used to provide outdoor lighting or hanging of the poles, etc. · Due to the need for carrying and stable placement, in addition to the footrest 2 folding foot 2 Outside the basic structure (please refer to the first figure, the first figure - A and the third figure - A, _B), the frame body is usually set as a telescopic structure with multiple inner and outer sleeves 2 2 sleeves. To achieve a proper Wei-regulating Wei that can be extended or adjusted to its height, is it mainly for each set of sleeves? 22 (Q) The side of the top section, by opening the bolt hole 2 £ 1, the call is provided - can __ lock the outer bolt 2 2 2, when the outer bolt 2 2 2 is locked inward to the bottom section, The bottom end of the plug body is adapted to progressively press the side of the sleeve 2 2 ^) which is sleeved inside the inner circumference, so that the inner sleeve 2 2 (1) is strongly chased backward and is inside the outer sleeve 22 (0). It is positioned and restrained so that the inner sleeve 22 does not slip or fall. The lock lag function of the above-mentioned waste external bolt 2 2 2 has structural simplicity, but if it is required to completely lock and prevent the inner sleeve 2 2 (1) from falling, the outer bolt 2 2 2 will be excessively applied. This may cause the surface of the inner sleeve 2 2 (I) to be broken or even recessed. M317204 Moreover, this kind of cake structure is produced by the pressure of the mine, and after the external screw inspection 2 2 2 is turned backwards, the force due to the compression and the lock lag disappears, and the inner casing 2 2 (1) stands: The weight is reduced and retracted into the outer casing 22 (◦); this causes the user's fear, or the sliding inner casing 2 2 (1) pipe end or its attachments, hanging objects, etc., the user is wrong; _ In the silk field, the weight of the heart, and the addition of the official control, weight specifications of the heavy-duty, large-scale tripod 2, the situation is more serious, and often there is a risk of tripod 2 full overturning. [New content] ' The main purpose of this creation is to provide a multi-section casing for the upper section of the tripod, and to provide an auxiliary structure with a segmented positioning, and to borrow money-_tube parts to set up the upper and lower inspection holes And in the upper section of the coat-by-coat or the sliding cover, respectively, the end bolts are respectively arranged to horizontally align the bolt holes, and the elastic insertion of the inner sleeve is pre-positioned, so that the device can cooperate with the original design. The _ press type on the wire is difficult to set. During the height adjustment process, the inner casing is suddenly lost due to the sudden loss of the wire force, and the danger or accident of the impact such as sliding down has an operational safety improvement effect. Its characteristics. The second purpose of this creation is to provide a multi-section sleeve for the upper section of the tripod, which provides a segmented positioning position. The auxiliary structure is provided. The outer end of the elastic plug is placed on the upper part of the outer sleeve or the middle part of the sliding sleeve. The embossing on the pedestal is provided with the word Wei trough, so that the bulging block provided by the lower end of the outer end of the elastic plug can be provided by the pull-in of the miscellaneous plug _ _ _ Cum to prevent the elastic plug from escaping unexpectedly; and the elastic plug can be turned outwards to make a transition, that is, the bump is positioned in the - word Wei_ outer edge, so that the inner sleeve is forced to lock on the outer sleeve After the device is unlocked, the height adjustment can be made freely. 6 M317204, the user has no control over the hand or the miscellaneous record, so the county device has excellent operation convenience and is characterized by it. [Embodiment] First of all, please refer to the first Europe, the first picture _ A and the second picture one A, - B: This case is the folding foot stand 2 of the pin riding 2 i, the upper part can be The multi-f inner and outer sleeves 22 for telescopic height adjustment are provided with a segmented positioning device; the upper and lower rows of bolt holes 22A are arranged one by one inside the casing 22, and the outer casings are sleeved one by one. 22 Shangyu section' or another for the restriction of the foot 2 i top section, the same part of the sliding sleeve 3 with the tightening bolt 3 ,, can be provided with through holes 2 2 B, 3A: through The outer end of the hole 2 2 B 3 A is fixed by the -gj rotary plug 4, and the inner end of the 4 1 end plug is horizontally aligned and inserted into the inner side of the inner sleeve 2 2 The hole 2 2 A is a pre-position of the nesting relationship of the sleeves 22 (as shown in the third figure _8); or is stretched backwards and backwards via the positioning bolt 41, and is detached from the inner sleeve f2 2 When the hole 2 2A is inserted, the inner sleeve 22 which is restrained by the positioning pin 4i is lost, and the outer bolt 2 2 2 is provided on the outer sleeve 2 • 2, and the sliding sleeve 3 is tightened and the screw is checked. And cancel the inside After the tight restraint of the g 2 2, the height adjustment operation (as shown in the second figure 1B) of the freely extending or retracting is performed; wherein the elastic plug 4 mainly includes - having the central shaft hole 4 The pedestal 4 2 is provided with the locating pin 4 丄 front end of the shaft hole 421 provided with an enlarged end, and the annular compression spring 43 is pre-set through the plug body, and then extended and combined with the pull handle 44 to form the positioning pin 41. = pre-propulsion, revealing the elastic function of the bolt; in addition, the front side of the bolt seat 4 2 is provided with a pre-shaped slot 4 2 2; so that the slot 4 2 2 is provided with a pull handle 4 4 is set to the M317204 The bump 4 41 which is similar to the missing slot 4 2 2 is slightly inserted into the slot 4 2 2 when the positioning bolt 41 is pulled back due to the elastic force of the inner segment spring 4 3, and the positioning is achieved. Preventing the elastic plug 4 from being accidentally removed from the inner sleeve 2 2 (such as the elastic plug 4 shown on the (F) side in the third figure), and being pulled back by the pull handle 44, When the positioning pin 41 is compressed by the inner portion of the magazine 4 - 3 so that the bolt head is retracted into the shaft hole 4 2 1 , the protrusion 4 4 1 can be adjusted by the user slightly after the sleeve 4 4 2 is completely withdrawn. Can make The bottom end of the block 441 is turned to the side of the outer edge of the indentation slot 4 2 2. After the user releases the handle 4 4 , the elastic force of the magazine 4 3 is pulled back, and the handle 4 4 is formed. The outer edge of the slot 4 2 2 is positioned and spanned, and at the same time, the end of the positioning bolt 41 is fixedly retracted into the shaft hole 4 21; thus, the outer bolt 222 provided on the outer sleeve 2 2 can be screwed back or slipped. The sleeve 3 is tightened by the bolt 31, and after the tight restraint of the inner sleeve 22 is released, the height adjustment operation for freely extending or retracting is performed. The user does not need to control or operate the elastic plug 4 (for example). The elastic plug 4) shown in the (H) side of the third figure is so convenient even if the rest is placed with Wei Jialai. Lu's comprehensive case can provide a convenient and safe operation effect of the telescopic telescopic casing, which is in line with the establishment of the new patent.
