Accordingly, the primary object of the present invention is to provide a sandglass assembly, wherein the height and orientation of the bottle of the sandglass assembly with respect to the shaft is adjustable so that the bottle is adjusted to a position in that the bottle can be seen clearly. Furthermore, the bottle is turnable easily and the flow direction of the sands in the bottle can be seen easily.
To achieve above objects, the present invention provides a sandglass assembly which comprises a seat having a stand shaft; a bottle being a transparent body and containing with sands; two symmetrical receiving grooves being formed within the bottle for receiving sands; a sand hole being formed between the two symmetrical receiving grooves for communicating the two receiving grooves; a predetermined amount of sands can pass through the sand hole; a frame for retaining the bottle; and the two receiving grooves are viewed clearly; a connecting unit installed between the shaft and the frame; and the connecting unit being liftable, descendable and rotatable along the shaft; the frame being rotatable along the connecting unit so that the bottle retained to the frame is turnable.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
Referring to FIGS. 1 to 3, the structure of the present invention is illustrated. The present invention has the following elements.
A seat 1 has a stand shaft 10. A top of the shaft 10 has a threaded section 11 for screwing a limiting block 12.
A bottle 2 is a transparent body. Two symmetrical receiving grooves 20 are formed within the bottle 2 for receiving sands 21. A sand hole 22 is formed between the two symmetrical receiving grooves 20 for communicating the two receiving grooves 20. A predetermined amount of sands can pass through the sand hole 22.
A frame 3 has a frame strip 30, two pads 31, and two screw units 32.
Two ends of the frame strip 30 extend to two outer sides of the bottle 2. Each end of the frame strip 30 has a through hole 300. A center portion of the frame strip 30 has a slot 301. Furthermore, the frame strip 30 has a shape like “3”.
Each pad 31 has a threaded post 310 capable of passing through the through hole 300. Thereby the two pads 31 are positioned and clamp two ends of the bottle 2. Each pad 31 has a buffer layer at a side of the pad 31 contacting the bottle 2 for buffering the pressure between the bottle 2 and the pad 31.
Each screw unit 32 has a screw hole 320 for receiving the stem 310 passing through the through hole 300 so that the ends of the frame strip 30 are clamped between the two pads 32.
A connecting unit 4 has a retainer 40 and a rotary unit 41. The retainer 40 has a via hole 400 for receiving the shaft 10. One side of the connecting unit 4 has an adjusting screw hole 401 which is communicated to the via hole 400. An adjusting screw 402 screws into the adjusting screw hole 401. Another side of the connecting unit 4 is formed with a groove 403 and a lateral side of the groove 403 is formed with a limiting screw hole 404 which is communicated to the groove 403. A limiting screw 405 is screwed to the limiting screw hole 404.
One end of the rotary unit 41 has an embedding block 410 capable of being embedded into the slot 301 of the frame strip 30. A retaining screw 302 serves to retain the frame strip 30 to the rotary unit 41. Another end of the rotary unit 41 has a projection 411 capable of being inserted into the groove 403 so that the rotary unit 41 is rotatable around one side of the retainer 40. A periphery of the projection 411 is embedded with an O ring 412 and is formed with an annular trench 413. The O ring 412 serves to increase the friction force between the rotary unit 41 and the retainer 40 as the rotary unit 41 rotates around the retainer 40 so as to avoid the undesired rotation of the bottle 2. The annular trench 413 serves to receive the limiting screw 405 to prevent the release out of the rotary unit 41 from the retainer 40.

Therefore, by above mentioned structure, the height and orientation of the bottle 2 with respect to the shaft 10 is adjustable so that the bottle 2 is adjusted to a position in that the bottle 2 can be seen clearly. Furthermore, the bottle 2 is turnable easily and the flow direction of the sands in the bottle 2 can be seen easily.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
