Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 2, the utility model discloses a simple and easy desk of movable, including main frame 1, main frame 1 is fixed with main desktop 11, and main frame 1 sets up in main desktop 11 side and supports main desktop 11 through the connecting piece of "concave" style of calligraphy to make and have certain space between main frame 1 and the main desktop 11. At one end of the main table top 11 in the length direction, the main frame 1 is rotatably connected with a rotating shaft 3, the top end of the rotating shaft 3 is connected with an auxiliary table top 2 (as shown in fig. 3-4), the rotating shaft 3 is connected with one end of the auxiliary table top 2 in the length direction, the auxiliary table top 2 is rotatably connected with the main frame 1 through the rotating shaft 3, the auxiliary frame 21 is further fixed at the other end of the auxiliary table top 2 in the length direction, and the auxiliary frame 21 and the rotating shaft 3 support the auxiliary table top 2. The length of the auxiliary table top 2 is greater than that of the main frame 1, and the thickness of the auxiliary table top 2 is smaller than the height of the space between the main frame 1 and the main table top 11, so that the auxiliary table top 2 can rotate to the position between the main table top 11 and the main frame 1, and the function of reducing the accommodating space is achieved.
The main frame 1 is fixed with a round platform type elastic piece 32, run through in the middle of the elastic piece 32 and cup joint with the pivot 3, the great one end orientation of elastic piece 32 bore is fixed with the main frame 1, the outer peripheral face of the elastic piece 32 is opened with the external screw thread, the nut 33 has still been cup jointed in the less one end of elastic piece 32 bore to the pivot 3, nut 33 and the less one end screw-thread fit of elastic piece 32 bore, and press from both sides tight elastic piece 32 through screwing up with elastic piece 32 screw thread, make elastic piece 32 press from both sides tight pivot 3, and then realize the function of fixing pivot 3 with main frame 1, can be when the user need not rotate vice desktop 2, it is fixed with vice desktop 2.
The main tabletop 11 is arranged to extend to one side of the rotating shaft 3 in such a length that the main tabletop 11 does not extend above the auxiliary tabletop 2 when the auxiliary tabletop 2 is perpendicular to the main tabletop 11. And be fixed with two universal wheels 211 at auxiliary frame 21 lower extreme, universal wheel 211 and ground butt to make the sliding connection on auxiliary frame 21 and ground become roll connection, the vice desktop 2 of rotation is lighter convenient, has further improved the practicality of this desk.
As shown in fig. 5 to 6, a rectangular positioning block 31 is fixed at the top end of the rotating shaft 3, a sliding groove 22 is formed in the lower end surface of the sub-table top 2 along the length direction, the sliding groove 22 is matched and clamped with the positioning block 31, the positioning block 31 slides in the sliding groove 22 relative to the sub-table top 2, so that the sub-table top 2 slides relative to the main frame 1 through the matching of the sliding groove 22 and the positioning block 31, the sub-table top 2 can slide relative to the main frame 1, and the sub-table top 2 can rotate around the main frame 1 along with the rotating shaft 3 because the sliding groove 22 is clamped with the. The sliding groove 22 is provided with a covered edge 23 which is equal to the sliding groove 22 in length direction, the covered edge 23 is arranged at the opening position of the sliding groove 22, and the covered edge 23 has a limiting effect on the positioning block 31 in the sliding groove 22 in the vertical direction, so that the auxiliary tabletop 2 can be prevented from being separated from the positioning block 31. Two reinforcing ribs 5 are further fixed on the lower end face of the auxiliary tabletop 2 along the length direction, and the reinforcing ribs 5 are parallel to the sliding grooves 22 and distributed on two sides of the sliding grooves 22. Through setting up vice desktop 2 to the form that slides with locating piece 31 relatively, make this desk can pass through the slip of vice desktop 2 to main desktop 11 both sides transmission article such as file to through vice desktop 2 and the joint cooperation of pivot 3, make vice desktop 2 can be through adjusting the angle that vice desktop 2 stretches out around main frame 1 rotation, improved the practicality.
as shown in fig. 7 to 8, three slots 24 are further equidistantly formed in the upper end surface of the wrapping edge 23 along the length direction of the sliding groove 22, the slots 24 can be in clamping fit with the positioning blocks 31, and the three slots 24 are respectively located at the two ends and the middle point of the wrapping edge 23. The main frame 1 is further connected with a pedal 4 in a sliding mode, the pedal 4 slides up and down relative to the main frame 1, protruding blocks 41 protrude from two sides of the pedal 4 respectively, and the pedal 4 slides up and down through the fact that the protruding blocks 41 are connected with the main frame 1 in a clamping mode. The shaft 3 is rotatably connected to the protrusion 41, the shaft 3 can rotate relative to the pedal 4, and the shaft 3 and the positioning block 31 move up and down along with the pedal 4 when the pedal 4 slides up and down. Therefore, when the positioning block 31 moves downwards to be clamped with the clamping groove 24, the rotating shaft 3 and the positioning block 31 limit the sliding direction of the auxiliary tabletop 2, so that the auxiliary tabletop 2 cannot slide; when the user lifts the pedal 4 with his foot, the positioning block 31 is disengaged from the engaging groove 24, so that the sub-table 2 can slide relative to the positioning block 31. And then realized that vice desktop 2 can carry out spacingly in the position of three draw-in grooves 24 according to user's wish, played the effect of conveniently writing and transmitting.
The implementation principle of the embodiment is as follows:
When the office table is used as a counter, when files or other objects need to be transferred on two sides of the main table top 11, a user in the counter can lift the pedal plate 4 by feet, the clamping matching between the positioning block 31 and the clamping groove 24 is released, so that the auxiliary table top 2 can slide on the positioning block 31, the files and the like can be placed on the auxiliary table top 2 in a martial flat manner, the auxiliary table top 2 is pushed to the other side of the main table top 11, and the function of conveniently transferring the objects is realized by sliding the auxiliary table top 2.
When the vice desktop 2 is accomodate to needs, can unscrew the threaded connection of nut 33 and elastic component 32, make elastic component 32 release pivot 3 to can rotate pivot 3, rotate vice desktop 2 to between main desktop 11 and the main frame 1, thereby realize reducing this desk occupation space's function, be convenient for accomodate and transport.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
