The inner tube extends through the outer tube; a control element drives a push block, the push block is disposed in the inner tube, and the push block is provided with at least one inclined surface a latching element disposed in the inner tube, the latching component being snapped into the corresponding through hole, and the latching component is provided with a moving block, the moving block being elastic Pushed on the inclined surface of the push block.

This creation has the following advantages:

1. The triggering part of the creation is set at the position below the seat, so the user can pull it when reaching out, and can adjust without bending down, so it has the effect of convenient operation.

2. The structure of the creation is quite simple and easy to operate, and the height of the seat can be adjusted arbitrarily and quickly.

First, please refer to the first, second and third figures. The creation includes an organic seat (1), a seat (2), a control element (3) and a cassette element (4), wherein:

a base (1) is provided with a hollow outer tube (11), and a plurality of through holes (12) are formed on the outer tube (11) by punching, and the outer tube (11) a slanting piece (13) is disposed at a position corresponding to each of the through holes (12), and a telescopic protective tube (14) is disposed on the outer edge of the outer tube (11). The tube (14) can be a bellows tube structure.

a seat (2) is movably disposed on the base (1), and a hollow inner tube (21) is disposed at a bottom of the seat (2), and the inner tube (21) extends through the outer tube ( 11) The inner tube (21) is fixedly provided with a fixing portion (211), the fixing portion (211) is provided with a first screwing portion (212), and a positioning seat (22) is provided with a second screwing portion. The portion (221) is screwed and fixed to the first screwing portion (212), and the receiving seat (22) is provided with a receiving groove (23) (as shown in the fourth figure), and the inner tube (the inner tube ( 21) The inner system is provided with a joint portion (24).

The control element (3) is provided with a pivoting portion (31) pivotally connected to the inner tube (21) of the seat (2) (as shown in the fifth figure), and the control element (3) is provided with a The pulling portion (32) protrudes from the inner tube (21), and the control member (3) is provided with a pulling portion (33) between the pivoting portion (31) and the pulling portion (32). The pull portion (33) is pivotally connected with a pull rod (34), and the pull rod (34) is connected with a push block (35), and the push block (35) is connected with a first elastic member (36). An elastic member (36) is fixed to the joint portion (24) in the inner tube (21), and the elastic member of the first elastic member (36) is actuated to elastically reset the push block (35). The push block (35) is provided with two opposite inclined faces (37), and a slot (38) is disposed between the two inclined faces (37).

a latching member (4) is disposed in the receiving groove (23) of the positioning seat (22) and extends through the slot (38) of the pushing block (35), the latching member (4) ) is provided with a latching portion (41) that is snapped into the corresponding through hole (12) and protrudes into the inclined piece (13) to be restrained. The outer tube (11) and the inner tube (21) are relatively fixed, and the cassette element (4) is sleeved with a second elastic element (42), and the moving block (43) is provided with an opening (431). Further, the latching member (4) is provided with a threaded section (44) which passes through the opening (431) of the moving block (43) and is screwed to a nut (45). Fixed, such that the moving block (43) is elastically urged on the opposite inclined surface portion (37) of the push block (35), so that when the push block (35) moves vertically, the two inclined faces (37) are utilized. ), the latching element (4) can be pushed to move horizontally in the receiving slot (23) of the positioning seat (22).

When it is necessary to adjust the height of the seat (2), as shown in the sixth and seventh figures, it is only necessary to manually pull the triggering portion (32) of the control element (3) upward by the pivotal connection. The portion (31) moves upward for the axis. When the control element (3) moves upward, the pulling portion (33) can be simultaneously driven to move the pull rod (34) upward, when the pull rod (34) is inside. When the tube (21) moves, the push block (35) of the pull rod (34) is also pulled upward, and the first elastic member (36) is stretched and joined, due to the two inclined faces of the push block (35). (37) is pressed against the moving block (43) of the latching member (4), so that when the push block (35) moves upward, the two inclined faces (37) are vertically moved upward, because The cassette element (4) is horizontally confined in the receiving groove (23) of the positioning seat (22), so that the two inclined surfaces (37) are vertically upward, and at the same time, a horizontal thrust is generated to push the moving block ( 43) and causing the latching member (4) to retract in a horizontal direction in the positioning seat (22), so that the latching portion (41) of the latching member (4) compresses the second portion The elastic member (42) exits the through hole (12), The outer tube (11) and the inner tube (21) are no longer restricted from being relatively fixed. Thus, the inner tube (21) can be pulled up and down relative to the outer tube (11) to adjust the seat (2). To the most appropriate height; when the adjustment is completed, simply release the hand and no longer pull the triggering portion (32) of the control element (3), then the push block (35) of the pull rod (34) will be subjected to the The elastic restoring force of the first elastic member (36) causes the push block (35) to return to the positioning, and the two inclined faces (37) of the push block (35) no longer push the latch member (4) upward. Moving the block (43), and the moving block (43) can no longer be subjected to the horizontal thrust, the latching portion (41) of the latching member (4) is subjected to the second elastic member (42) The elastic restoring force causes the latching member (4) to return to the original position, so that the latching portion (41) of the latching member (4) is again clamped in the through hole (12) (eg The figure 8 is shown and protruded to the slanting piece (13) to be restrained, thereby limiting the outer tube (11) and the inner tube (21) to be relatively fixed, thereby completing the seat (2) ) The lifting adjustment.

In addition, the creation can also directly move the seat (2) upwards, thereby driving the inner tube (21) to move upward relative to the outer tube (11), and the inner tube (21) moves upward while the card The latching portion (41) of the cymbal component (4) will touch each slanting piece (13), causing the latching portion (41) to be retracted to compress the second elastic member (42), thereby not being stuck Between the through hole (12), the seat (2) can be raised to a proper position, and the card member (4) is jammed when the seat (2) is no longer pulled up. The portion (41) is subjected to the elastic restoring force of the second elastic member (42), and the latch member (4) is returned to the original position, so that the latch portion (41) of the latch member (4) is stuck. The inner tube (11) and the inner tube (21) are relatively fixed to each other in the through hole (12) and protruded against the inclined piece (13).

However, the above is only one of the examples of this creation. When it is not possible to limit the scope of the patent protection of this creation, the simple equivalent changes and replacements made by the scope of the patent application and the contents of the specification are all It shall remain within the scope of the protection covered by the scope of this patent application.
