SUMMERY OF THE UTILITY MODEL
Utility model purpose: in view of the above problems, it is an object of the present invention to provide a rack capable of switching the direction in two horizontal and vertical directions, and a transmission assembly having the rack.
The technical scheme is as follows: a rack capable of switching horizontal and vertical directions comprises a first rack and a second rack, wherein the first rack and the second rack are arranged in a front-back mode and connected, matched clamping grooves are formed in the connecting end portions of the first rack and the second rack, the second rack is buckled on the first rack and forms a vertical separation structure through hooking of the clamping grooves, the lower surfaces of the first rack and the second rack are tooth surfaces, and the upper surface of the first rack or the second rack is fixed with a conveying part.
Furthermore, the clamping groove is a U-shaped groove, on one hand, the first rack and the second rack are firmly hooked through the U-shaped clamping groove, on the other hand, the first rack and the second rack can be vertically separated after being relatively vertically moved away, and an ingenious hooking fixing and vertical separating structure is formed.
A transmission assembly comprises the rack capable of switching horizontal and vertical directions, a gear and a support, wherein the gear is arranged on the support in a supporting mode, when a first rack and a second rack are hooked, one of the first rack and the second rack which can be vertically separated downwards is meshed with the gear, a boss is arranged on the two side faces of the other rack in the width direction, a positioning penetrating groove is formed in the inner side face of the support along the transverse moving direction of the rack capable of switching horizontal and vertical movements, and the positioning penetrating groove is matched with the boss.
Furthermore, the clamping groove is a U-shaped groove, the opening of the first rack is upward, and the opening of the second rack is downward. At this time, when the transmission member is fixed to the upper surface of the first rack, if the length of the transmission member is increased to the second rack, a through hole is opened in a region of the transmission member corresponding to the second rack.
Has the advantages that: compared with the prior art, the utility model has the advantages that: through the rack and gear rack transmission pair with the vertical separation structure, the problem of conversion between horizontal displacement and vertical displacement of the conveying part is solved, the motions in two directions do not influence each other, the structural design is ingenious, and the operation is flexible.

Detailed Description
The invention will be further elucidated with reference to the drawings and specific embodiments, which are intended to illustrate the invention and are not intended to limit the scope of the invention.
The utility model provides a rack of changeable level, vertical direction, as shown in the attached figure 1, 2, including first rack 1, second rack 2, first rack 1, second rack 2 lays in the front and back and is the straight line, matching draw-in groove 3 is seted up to both's connection end, draw-in groove 3 is U type groove, set up on its upper surface and the opening upwards on first rack 1, set up on its lower surface and the opening downwards on second rack 2, the second rack is detained and is put on first rack, both form the hookup through the draw-in groove, the second rack supports through first rack and does not fall, form vertical separation structure when both move in vertical direction reverse, the lower surface of first rack 1, second rack 2 is for 4 with the driven flank of tooth of gear engagement, the upper surface of first rack 1 or second rack 2 is fixed with the conveying part.
It can be seen that: if the gear is meshed with the first rack to form linear displacement in the horizontal direction, no matter the transmission part is fixed with the upper surfaces of the first rack and the second rack, when the gear is transmitted from the first rack to the second rack, the transmission part can form displacement in the vertical direction along with the gear because the clamping grooves hooked by the first rack and the second rack can be separated in the vertical direction; if the gear is first engaged with the second rack to form a linear displacement in the horizontal direction, the same is true.
A transmission assembly, as shown in fig. 3-5, comprising the above-mentioned rack capable of switching between horizontal and vertical directions, a gear 5 and a bracket 6, wherein the gear 5 is mounted on the bracket 6.
For convenience of description, the U-shaped groove of the clamping groove 3 is formed in the upper surface of the first rack 1, the opening of the U-shaped groove is upward, the lower surface of the second rack 2 is formed, the opening of the second rack is downward, and the gear is meshed with the first rack to form linear displacement in the horizontal direction. The second rack 2 is provided with bosses 7 on both sides in the width direction, and a positioning through groove 8 matched with the bosses 7 is formed on the inner side surface of the bracket 6. Along with the gear revolve, the gear by with first rack meshing, and then to meshing with the second rack, and during this while the boss penetrated the groove in the location, then the second rack further can support through the support, first rack and gear disengage the back, first rack vertical separation downwards.
The transfer member forms a displacement in a vertical direction with respect to the first rack if the transfer member is fixed with the upper surface of the second rack, and forms a displacement in a vertical direction with respect to the second rack if the transfer member is fixed with the upper surface of the first rack. If the transmission part is fixed with the upper surface of the first rack and the length of the transmission part is extended to the second rack, a through hole 9 is arranged on the transmission part 10 corresponding to the area of the second rack 2, when the transmission part moves downwards along with the first rack, the second rack stays on the gear and the second rack passes through the through hole, and the downward movement of the transmission part is not influenced.
The utility model discloses a rack, rack and pinion transmission that have vertical isolating construction are vice, have solved the conversion problem of transfer unit horizontal displacement and vertical displacement, and the motion of two directions does not influence each other, and structural design is ingenious, and the operation is nimble.
