Description

Technical Field

[0001] The utility model relates to the field of toy balances, and particularly relates to a detachable balance operation frame device that can be assembled. Background Art

[0002] A balance is an instrument used to accurately measure the mass of an object and is widely used in fields such as scientific research, education, medicine, and industry.

[0003] When making a balance into a children's learning toy, it usually consists of a bracket, a suspension arm, and a carrying tray. The suspension arm is rotatably installed through a shaft rod and a bolt.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] The present invention provides a Figures 1-3 combinable and detachable balance operating frame device as shown, including a support assembly 1, a support arm assembly 2 and a tray assembly 3. The support arm assembly 2 is rotationally clamped in the middle of the front surface of the support assembly 1. The tray assembly 3 is hung on the hanging torsion bar 23. The support arm assembly 2 includes a connecting plate member 21, two cantilever plates 22, a hanging torsion bar 23 and a digital scale 24. The connecting plate member 21 is rotationally clamped in the middle of the front surface of the support assembly 1. The cantilever plates 22 are installed on the front surface of the connecting plate member 21. The two cantilever plates 22 are symmetrically installed on the front surface of the connecting plate member 21. The two cantilever plates 22 correspond to the two tray assemblies 3. The hanging torsion bar 23 is fixedly connected to the front surface of the cantilever plate 22. The digital scale 24 is arranged on the front surface of the cantilever plate 22. The digital scale 24 corresponds to the hanging torsion bar 23 one by one, and the digital scale 24 increases sequentially from the side close to the connecting plate member 21. And the number of the multiple hanging torsion bars 23 is multiple. Thus, when the two tray assemblies 3 are hung on the two cantilever plates 22 and the two cantilever plates 22 are in a horizontal state, the weight ratio of the objects on the two tray assemblies 3 can be correspondingly obtained according to the numbers corresponding to the hanging torsion bars 23 on which the two tray assemblies 3 are hung on the two cantilever plates 22.

[0028] Furthermore, the support assembly 1 includes a support plate 11, an arc plate 12 and a hanging bolt 13. The arc plate 12 is fixedly connected to the top of the support plate 11. The hanging bolt 13 is installed on the front surface of the support plate 11. The hanging bolt 13 corresponds to the connecting plate member 21. A bottom plate 14 is arranged at the bottom of the support plate 11. A mounting bracket 15 is fixedly connected to the top of the bottom plate 14. The support plate 11 is vertically installed on the top of the bottom plate 14 through the mounting bracket 15.

[0029] In particular, a through hole 28 larger than the end size of the hanging bolt 13 is formed on the front surface of the connecting plate member 21. A clamping groove 29 is formed at the top of the inner wall of the through hole 28. The outer wall of the hanging bolt 13 is rotationally clamped with the clamping groove 29. Moreover, the size of the inner cavity of the clamping groove 29 is slightly larger than the size of the outer wall of the hanging bolt 13, and the size of the inner cavity of the clamping groove 29 is smaller than the size of the end of the hanging bolt 13. Thus, when the connecting plate member 21 is rotationally clamped with the hanging bolt 13 through the clamping groove 29, the connecting plate member 21 can be stably and rotationally installed on the front surface of the support plate 11. And when the connecting plate member 21 is moved upward relative to the hanging bolt 13 to make the hanging bolt 13 inside the through hole 28 on the connecting plate member 21, the connecting plate member 21 can be separated from the hanging bolt 13, so as to disassemble or install the connecting plate member 21. A protruding pointer 25 corresponding to the arc plate 12 is fixedly connected to the top of the connecting plate member 21. Mounting bolts 26 are symmetrically installed on the front surface of the connecting plate member 21. The outer wall of the mounting bolt 26 is rotationally inserted and sleeved with the cantilever plate 22. A support block 27 is arranged at the bottom of the front surface of the connecting plate member 21. The top of the support block 27 is attached to the cantilever plate 22. Under the limitation of the support block 27 and the mounting bolts 26, the two cantilever plates 22 are in an unfolded horizontal state. And when the connecting plate member 21 is removed, the cantilever plates 22 can rotate relative to the mounting bolts 26 to make the two cantilever plates 22 in a folded parallel state, as Figure 3 shown, so as to facilitate its storage.

[0030] Specifically, the tray assembly 3 includes a carrying tray 31, a connecting rope 32 and a hanging ring 33. The carrying tray 31 is used for carrying the measured object. The end parts of the connecting rope 32 are respectively fixedly connected with the hanging ring 33 and the carrying tray 31. The hanging ring 33 is hung on the outside of the hanging torsion bar 23. And the number of the connecting ropes 32 is three. The hanging ring 33 is located above the center of the carrying tray 31. Thus, when an object is placed on the carrying tray 31, under the action of the three connecting ropes 32, the center point of the carrying tray 31 is still located on the vertical extension line of the hanging ring 33. Thus, the hanging ring 33 is hung on the hanging torsion bar 23, so that the center of gravity of the carrying tray 31 and the object is located at the bottom of the vertical extension line of the hanging torsion bar 23.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
