Description
Technical field
The invention belongs to technical field of sewing machines, are related to a kind of folding table top structure of sewing machine.
Background technique
On sewing machine usually all have mesa structure, for placing sewing etc., industrial sewing machine since whole equipment is larger,
It will appear transport and the inconvenient situation of storage, such as into elevator when may cannot be introduced into electricity because platen structure is excessive
Ladder；It is big additionally, due to the volume for being packaged shared, it needs using more protection timber, transportation cost is larger.At present on the market also
The platen structure of some is that platen will be assisted to be divided into muti-piece, is re-assemblied again after dispersion transport, but usually by
More in the block number of platen segmentation, assembling is time-consuming and laborious, and will affect beauty, also largely will appear and scrapes showing for template
As.
China's patent (notification number: CN104593960B；Publication date: 2018-08-21) a kind of template sewing machine, including machine
Frame, head and working plate, working plate are arranged on the rack, and working plate includes the platen ontology being fixed on the rack, machine
Head is located on platen ontology, and platen ontology side corresponding with head front end is provided with preceding platen, the bottom point of preceding platen two sides
It is not fixed with the preceding platen connector in elongated and prominent foreground board bottom portion, each preceding platen connector is close to platen ontology
One end is rotatablely connected with rack by front rotary shaft respectively, and front rotary shaft is located at foreground plate bottom part down, it is each before platen connector with
Platen and platen ontology are located at the locking mechanism one of same level before being respectively provided with platen before capable of supporting between rack and making.
Working plate in above patent document has the preceding platen that can be folded, and can adjust workbench to a certain extent
The volume of plate, but the preceding platen can only be rotated hingedly, adjustability is poor, cannot fully meet the stretching, extension demand of working plate.
Summary of the invention
The present invention addresses the above problems in the prior art, provides a kind of folding table top structure of sewing machine, this hair
It is bright the technical problem to be solved is that: how guarantee template machine table top globality structure function in the case where, improve be packaged
The convenience of transport table and the convenient and reliable property of installation.
Object of the invention can be realized by the following technical scheme:
A kind of folding table top structure of sewing machine, sewing machine includes rack, which is characterized in that the folding table top structure packet
The main platen in rectangle is included, the main platen is installed in the frame upper end, and one end of the main platen is connected by hinge one
Assist platen before having, the two sides of the main platen are respectively equipped with left redundant platen and right redundant platen, the left redundant platen with
Between the main platen, between the right redundant platen and the main platen by can make the left redundant platen with it is described
Right redundant platen swings the connection component folded and is connected, and the left redundant platen can also be described with the right redundant platen
Length direction on connection component along the main platen moves；The left redundant platen, right redundant platen and preceding auxiliary platen
Support construction is additionally provided between the rack.
Further, in the folding table top structure of above-mentioned sewing machine, the support construction includes rack two sides difference
The outer end of the left support frame and right support frame of setting, the left support frame and right support frame extends outwardly and can swing, described
The upside of left support frame and the bottom of the left redundant platen are detachably connected, the upside of the right support frame and the right redundant
The bottom of platen is detachably connected；The support construction further include the rack and it is preceding auxiliary platen between be arranged can fold
Or flexible support component.
Its working principles are as follows: left redundant platen, right redundant platen are located at left and right sides of main platen and pass through connection group
Part and main platen are rotatablely connected, and preceding auxiliary platen is located at the front end of main platen, are rotatablely connected, are being needed by hinge with main platen
When this mesa structure of packing and transporting, preceding auxiliary platen, left redundant platen, the right redundant platen of table top are put down, make its overturning folding
It is folded, in the case where tall auxiliary mesa and main platen one, reduces the area of entire mesa structure, facilitate packing and transporting；And pacifying
Dress is in use, stretching, extension is convenient and efficient.When assembling, main platen is installed in frame upper end, by preceding auxiliary platen, left redundant platen, the right side
Auxiliary platen strut, left redundant platen is supported by left support frame, right redundant platen by right support frame to its into
Row support, preceding auxiliary platen are supported by support component；When entire sewing machine storage or transport, left support frame, the right side
Support frame and support component can shrink abutting on the rack.Mesa structure in the technical program can be installed at any
It is versatile on template machine；It can accomplish that size is minimized when folding, and can retain table top when strutting to greatest extent again
The structure of globality has very big advantage in packing and transportation cost, while can keep mesa structure to the full extent
Flatness, reduce the probability for scraping template.
In the folding table top structure of above-mentioned sewing machine, the two sides of the bottom of the main platen have installation stringer；It is described
Installation stringer is installed in the frame upper end, and the connection component includes the sliding rail mounting base being mounted on the installation stringer,
The sliding rail mounting base is installed with the guide rod along the main platen length direction, the left redundant platen and the right redundant platen
Bottom is installed with sleeve, and the sleeve is rotatably socketed on the guide rod and the sleeve can slide on the guide rod,
It is additionally provided on the sleeve by the lock-screw of the sleeve and the guide rod locking.
As an alternative, guide rod can be set in left redundant platen and right redundant platen bottom, and sleeve is arranged at main
The bottom of plate；Or sleeve is replaced using structures such as sliding blocks.
Using the above structure in connection component, left redundant platen and right redundant platen are rotated by rotary shaft of guide rod, into
Row folds, and when being packaged, can reduce the area of mesa structure, and upon deployment, left redundant platen and right redundant platen can edges
Guide rod direction translation, facilitate adjustment left redundant platen and right redundant platen position.Left redundant platen and right redundant platen exist
Horizontal direction can translate, while can rotate around guide rod circumferential direction.Main platen and sliding rail mounting base are tight during the installation process
Patch, left redundant platen and right redundant platen in the expanded state, are close to sliding rail mounting base upper side, utmostly be ensure that
