The utility model discloses an abacus frame construction is reasonable, and outer frame body, inner frame body, well roof beam strip all are the fashioned prefabricated part of integral type, and the assembly operation of each part is very convenient, and ordinary workman need not the instrument and can go on, has improved production efficiency greatly, and the quality is more stable. Moreover, when the abacus needs to be repaired and adjusted, the frame can be conveniently disassembled and assembled, and the scrapping loss is reduced.

Description

Assembled abacus frame

The technical field is as follows: the utility model relates to an abacus, in particular to a frame of an abacus.

Background art: the structure of the abacus generally comprises a frame consisting of a frame and a centre sill, a stop lever, an abacus bead and the like. The frame usually needs the fixed connection of multistage frame strip and centre sill to form, and the requirement of production assembly is higher, and producers' operation technique must be skilled, and whole production efficiency is not ideal yet. Moreover, if the problems of bead defect, stop rod fracture and the like occur in the common fixed abacus, the abacus can not be disassembled and replaced generally and can only be scrapped.

The invention content is as follows: the utility model provides a reasonable structure, easy dismounting's pin-connected panel abacus frame to prior art's not enough.

The utility model comprises an outer frame body and an inner frame body which are connected in a sleeved mode, wherein the left side and the right side of the integrated inner frame body are both provided with bayonets, the two ends of the integrated middle beam strip are correspondingly clamped in the two bayonets, a row of stop rod through holes are uniformly arranged on the inner rule of the middle beam strip, and a plurality of stop rod end seats which are in one-to-one correspondence with the stop rod through holes are arranged on the front end surfaces of the upper side and the lower side of the inner frame body; the outer wall of the inner frame body is provided with a plurality of buckling holes, the inner wall of the integrated outer frame body is provided with a plurality of buckling feet, and the buckling feet are correspondingly buckled in the buckling holes respectively to form an inner and outer frame body connecting structure.

The utility model discloses an abacus frame structure is reasonable, and outer frame body, interior framework, well roof beam strip all are the fashioned prefabricated part of integral type, and the assembly operation of each part is very convenient, and ordinary workman need not the instrument and can go on, has improved production efficiency greatly, and the quality is more stable. Moreover, when the abacus needs to be repaired and adjusted, the frame can be conveniently disassembled and assembled, and the scrapping loss is reduced.

The invention is further described with reference to the accompanying drawings and the detailed description.

Description of the drawings: fig. 1 is a main schematic view of the embodiment.

Fig. 2 is a rear view of the outer frame body in fig. 1.

Fig. 3 is a bottom view of the center sill of fig. 1.

Fig. 4 is a front view of the inner frame of fig. 1.

Fig. 5 is a bottom view of fig. 4.

Fig. 7 is a sectional view taken along line B-B of fig. 1.

Fig. 8 is a cross-sectional view of C-C of fig. 1.

The specific implementation mode is as follows: as shown in fig. 1 to 7, the outer frame body 1 and the inner frame body 2 are connected in a sleeved manner, the left and right sides of the integrated inner frame body 2 are both provided with bayonets 4, two ends of the integrated middle beam strip 3 are correspondingly clamped in the two bayonets 4, a row of stop rod through holes 5 are regularly and uniformly arranged in the middle beam strip 3, and the front end surfaces of the upper side and the lower side of the inner frame body 2 are both provided with a plurality of stop rod end seats 6 which are in one-to-one correspondence with the stop rod through holes 5. The outer wall of the inner frame body 2 is provided with a plurality of buckling holes 7, the inner wall of the integrated outer frame body 1 is provided with a plurality of buckling feet 8, and the buckling feet 8 are correspondingly buckled in the buckling holes 7 respectively to form an inner and outer frame body connecting structure.

In this embodiment, a plurality of positioning holes 10 are further disposed on the front end surfaces of the upper and lower sides of the inner frame 2, and a plurality of positioning pins 11 are disposed on the corresponding positions on the inner wall of the outer frame 1, as shown in fig. 8, each positioning pin 11 is inserted into each positioning hole 10, so as to form a frame connection reinforcing structure. Therefore, the positioning is easier and more accurate during assembly, vibration displacement can be prevented, and the connection is more reliable.

In the embodiment, the bottom surface of the inner frame body 2 is provided with a transverse guide groove 9, and the bottom of the middle beam strip 3 is arranged in the guide groove 9. The assembly positioning of the middle beam strip 3 is convenient, the middle beam strip 3 is ensured not to shake, and the bottom is more stable.
