Passing through the guide groove, the pole for the sliding position is arranged on the fixing seat, the fixing component is connected to the _ by the Wei lock, so that the pivot shaft can rotate with the top block, and the two ends of the top block are provided with the roller. When turning the cymbal, the top block can be driven up, and the fixed seat and the nugget _ distance are extended, so that the lifting is carried by the wheel seat, so that the original brewing of the device is off the ground. The creation of this book is combined with the secrets of the secrets, which can be recorded by the rapid lifting of the wheel base (four), the foot of the county or the ground and the indefinite __ real scale. [Embodiment] The following 遂 combines the main technical features of the creation. Wei Wei thief _ is, the smack of the wheel is combined with the device that is not specific but can be moved and moved to obtain better moving operation effect, so the thin, tender _ butterfly wheel seat - see the first and second Tuqing, the set-fixed seat slip sliding tree tree explosion ^ need to move the sliding armor 6 M297861 pivoted on the mosquito seat 1 and the moving block 3_-General 2, and the wheel 4' combined with the moving block 3 & As shown in the first figure, the creation is based on the combination of the wheel base and the bottom of the dining car 5, and the bottom of the dining car 5 is further provided with a plurality of legs 5 3 . Referring to the third figure, the fixing seat i is composed of two adjacent side walls and two bridges between the two side walls, wherein the top wall is at the appropriate position. A limiting slot 1 1 1 is disposed, and both sides of the top wall 11 are respectively provided with a hole 112, and the two side walls 12 are respectively provided with at least three guiding grooves, 12 2 ' in the embodiment The slot i 2 i is located at the center of the side wall i 2 , and the holes 112 can respectively fix the catching member i 3 . In the embodiment, the hooking member is drilled at the head of the screw. The solid Mi can be fixed to the bottom of the dining car 5 by means of a screw lock. The top block 2 is provided with a plurality of rollers 21 corresponding to the end edges of the top blocks 2, and the top blocks 2 are disposed between the two side walls 12, and the top blocks 2 are respectively disposed at two ends of the top block 2 The pair of perforations 2 2 are located at the position of the guide 2!, and then the pivots are passed through the guide groove 121 and the end of the perforation 2 2 pivot 2 3 and then buckled by the buckle 2 31, and pivoted again. 2 3 is located at each of the guiding slots 121 and is respectively provided with a roller 2 7 , so as to support the pivoting movement of the pivot 2 3 to extend the groove 121 , so that the sliding block of the top block 2 can be pivoted on the fixing base 1 and topped. The block 2 is further locked by a fixing member 25 and abuts against the shaft of the pivot 2 3 , whereby the pivot 2 3 and the top block 2 can be rotated together, and the one end edge of the top block 2 is further A jack 2 6 is provided, which is formed in the embodiment by a latch that protrudes from the top block 2, and the jack 2 6 7 M297861 is preferably arranged to be lifted upward when the top block 2 rotates. On one side. In this embodiment, the pivot 2 3 is formed by a screw having a hexagon socket. The main purpose is to allow the user to penetrate the hexagonal hole into the hexagon socket of the pivot 2 3 when the wheel base is moved up and down. The rotating pivot 2 3 drives the top block 2 to rotate, but the pivot 2 3 can also be designed to have a grip (not shown), which allows the user to directly hold the grip by hand. It is more convenient to pull the pivoting shaft. The moving block 3 is composed of a flat portion 3 and two pivot portions 3 2 disposed on both sides of the flat portion 3. In the present embodiment, the moving block 3 is made of a metal plate material on both sides. a circular portion 32 is formed in a circular tubular shape, and each of the pivot portions 32 is formed with a perforation 3 21 ', and an outer side of each of the pivot portions 3 2 is provided with a protruding portion and a protrusion 3 3 having a hole. The moving block 3 is placed between the two side walls 丄2 of the seat y, and is located at the lower end position of the top block 2. 'The second thin rod 2 4 passes through the guide groove i 2 2 and the through hole 3 21 'The end of the cross rod 2 4 has an enlarged The head of the shape can be abutted on the side of the fixed block ==12, the crossbar 2 is wrong, the end is provided with the buckle 2 31, and the crossbars 24 are respectively located at the portion of the V-groove 122-roller 27 for supporting The crossbar 24 can extend the reciprocating movement of the slot 1 2 2, so that the moving block 2 can be slidably disposed on the fixed seat 1 and the two hooks i 3 of the bracket i and the two protrusions of the moving block 3 3, each of which is provided with an elastic tree 14 and the [end] 4 of the elastic member 14 is hooked on the head of the sentence holder 13, and the second end i 4 2 is hooked on the hole of the protrusion 3 (4). The elastic force of the spring element 14 is made so that the moving block 3 and the top block 2 can be Often holding located at the lowered position (the side closer to the top wall 11). The wheel 4 is pivotally provided with a roller 41 at the bottom, and the wheel 4 is pivotally mounted on the flat portion 31 of the moving block M297861 3 so that the bottom of the wheel base has a device for which the wheel 4 can be moved with less labor. Due to the limitation of the elastic force of the 7G piece, the wheel seat of this creation is in a descending state under normal conditions, as shown in the second figure, in this state, the wheel seat system combined with the bottom of the dining car cannot be repaid. Therefore, the foot 5 3 provided on the dining car 5 can be directly placed on the ground. Thus, the dining car 5 can be fixed so that it cannot move. Referring to the fourth figure, when the dining car 5 is to be moved, the pivot of each wheel seat can be rotated. 2 3 'The actual towel must be rotated by 六 2 3 with six shackles, driven by the pivot 2 3 The top block 2 rotates, and the roller 2 i of the top block 2 respectively contacts the lower end surface of the top wall χ 1 and the upper end surface of the flat portion 3丨, and since the length direction of the Wei 2 is larger than the top wall 11 and the moving block of the fixed seat 1 The distance between the planes 3 i of 3, so when the top block 2 rotates, the fixed seat i and the moving block 3 will be opened, so that the distance between the two is increased, and at this time, the ejector rod 6 on the side of the top block 2 6 Place the position in the slot until the ejector pin 26 abuts the limit slot: 丨! On the side, the top block 2 will not be allowed to continue to rotate in that direction, so that the miscellaneous operation can be performed to the material g, as shown in the fifth figure, in the lifted state of the wheel seat, due to the lifting of the dining car 5 The relationship, therefore, the foot 5 5 of the transfer car 5 off the ground, so that the dining car 5 can be moved. It should be noted that when the wheel base of the present invention is in the lifted state, the top block 2 is actually rotated at an angle greater than 90 degrees (above the top dead center of the circular motion), thereby preventing the push cart 5 from being pushed. The shock of its side, the top block 2 produces an unexpected reversal and retracts the wheel seat, creating operational hazards. In summary, this creation can conveniently and quickly lift the carried device, and it is beneficial for the operation of 9 M297861 in handling or moving. It is an excellent creation. It is in line with the new patent application requirements and is submitted in accordance with the law.
