A bolt runs through the screw and is lock arranged on the continuous moving shaft lever. The electric pump is parallel arranged at a proper position of the machine body. The driver unit is lock arranged on the electric pump shaft lever and resists the crank. The utility model is convenient to cover and protect, labor-saving to start, stable and smooth to pull and push, and can reduce low-volume noise.
Description
(1) technical field
The utility model is the drive unit about a kind of compress pin of Sewing machines.
(2) background technology
The compress structure of Sewing machines, be to be used for the cloth compacting is lived, so that a kind of device that sewing work is carried out, and when desire is interrupted sewing operation, just cloth-pressing device must be mentioned, the drive unit of in the past mentioning the compress pin is the below that is loaded on the support platform, and this drive unit is the device of a kind of pneumatic cylinder or oil hydraulic cylinder class, it spurs a connecting rod upwards, sees through push rod and changes application of force direction and see through connecting piece again one end of outer link is spurred downwards.
The above-mentioned drive unit of commonly using uses too much driving member, and if be located at Sewing machines inside, maintenance is very bothersome when mechanism damages, this connecting piece is the device of a chain shape, need to adjust its elasticity when mounted, and can be elongated gradually after the time is permanent, and then lose original tension force, and have influence on the operation precision of relevant parts, except that of a specified duration the fracture suddenly with the damage meeting ejected and damaging, because of should wholely organizing parts be that other device is below the support platform, the support platform also needs extra vacating space assembling drive unit, makes and strengthens the Sewing machines overall volume, but also want other perforate, except that assembling is keeped in repair than the difficulty, its connecting piece that is the chain shape is being pullled Shi Yihui generation collision noise.
Advanced design is to make drive unit into electromagnetic type to drive, TaiWan, China is as shown in Figure 1 announced the preceding case of " improvement of Sewing machines electromagnetic type pressing element drives structure " novel patent No. 443338, its structure comprises a Sewing machines, one is articulated in the outer linkage of this Sewing machines, one is arranged in the compress pin on this Sewing machines, wherein, install a Vidacare corp (being electrodynamic pump) in the outside of this Sewing machines, this drive unit is directly to contact with this linkage, connects this compress pin start of establishing in order to drive this Sewing machines.Be equiped with an adjuster on this linkage, this adjuster offers a groove, and respectively offers a slotted hole in the groove both sides, and is fixed on this linkage with two fixtures; And being pivoted one in the outside of Sewing machines, this promptly is arranged in above-mentioned groove and reaches purpose with the transmission of compress pin.
Electrodynamic pump on its structural design is because will cooperate original connecting rod, can only add with vertical mode and be located at outside the body, exceed board than regular meeting is obvious, whole machine body is increased, and outward appearance becomes rugged having some setbacks, and makes trouble of enclosure car system, and its design that directly links, because of rising and falling of connecting rod certain revolve a differential seat angle, so can produce vertical tremor during action, still have noise in the use.
(3) utility model content
The purpose of this utility model is to provide a kind of drive unit of compress pin of Sewing machines, and it has overall appearance, cover protects conveniently, starts laborsaving, smooth-going against pulling, as can to reduce sound noise advantage.
In order to achieve the above object, the utility model provides a kind of drive unit of compress pin of Sewing machines, it is characterized in that: comprising:
One body, this body are provided with the interlock axostylus axostyle of compress pin;
One crank, this crank is provided with a screw, and a bolt passes this screw and is locked on this interlock axostylus axostyle;
One electrodynamic pump, this electrodynamic pump is parallel to be located on this body;
One pusher, this pusher are locked on this electrodynamic pump axostylus axostyle and push this crank.
The drive unit of the compress pin of described Sewing machines is characterized in that: this crank can be the bending arc shape of Hili dart, is provided with bent arc in the middle of this crank; This pusher is one to be provided with the L type seat of screw, and this pusher one end is loaded on this electrodynamic pump axostylus axostyle by screw and pad lock, and this pusher end is in addition gone up interlocking one T type pulley, and this crank is resisted against on this pulley.
The drive unit of the compress pin of described Sewing machines is characterized in that: can be provided with dustproof snake abdomen cover on the two ends of this electrodynamic pump axostylus axostyle.
The drive unit of the compress pin of Sewing machines of the present utility model, can be along sliding compress pin pull-up with horizontal with Sewing machines against crank, the effect that not only can reach laborsaving, reduces noise, and because of electrodynamic pump parallel with the Sewing machines vehicle body, so can reduce the body ledge, increase overall aesthetic and cover and protect conveniently.
Form for enabling detail knowledge structure of the present utility model, lift the utility model preferred embodiments now, and conjunction with figs. be described as follows:
(4) description of drawings
Fig. 1: be the combination view of conventional construction.
Fig. 2: be combined planar schematic diagram of the present utility model.
Fig. 3: be sectional perspective exploded view of the present utility model.
Fig. 4: be action schematic diagram of the present utility model.
Fig. 5: be another action schematic diagram of the present utility model.
(5) specific embodiment
Extremely shown in Figure 5 as Fig. 2, the drive unit of the compress pin of the Sewing machines that the utility model is designed, it mainly comprises: a body 1, a crank 2, an electrodynamic pump 3 and a pusher 4 are formed; Wherein
This body 1 which is provided with the interlock axostylus axostyle 51 of compress pin 5;
This crank 2, the bending arc shape that is Hili dart is locked on the interlock axostylus axostyle 51 with the screw 22 of bolt 21 by crank 2, is provided with the parallel distance that bent arc is two ends to rise out in the middle of this crank 2;
This electrodynamic pump 3 parallelly is locked on appropriate position on the body 1, can be provided with snake abdomen cover (figure does not show) on the two ends of the axostylus axostyle 31 of electrodynamic pump 3 to reach dustproof purpose and effect;
This pusher 4 is the L type seat of band screw 41,42, and one end screw 41 is loaded on the electrodynamic pump axostylus axostyle 31 by nut 43 and pad 44 locks, other hold on the screw 42 with bolt 45 pass screw 462,42 interlockings one T type pulley 46 for cranks 2 against.
By this, be loaded on the interlock axostylus axostyle 51 with crank 2 locks during its combination, electrodynamic pump 3 level frames are located at appropriate position on the body 1, again T type pulley 46 is adorned appropriate after, and pusher 4 lock of L type is loaded on the electrodynamic pump axostylus axostyle 31, utilize the footpath of T type pulley 46 contract portion 461 for crank 2 suspend end against and slide, so when electrodynamic pump 3 starts, can and make 5 pull-ups of compress pin with crank 2 light sliding drives.
Wherein, 2 on electrodynamic pump axostylus axostyle 31 and crank because be utilize pulley 46 indirectly against, and electrodynamic pump 3 is horizontal mode starts, so revolve a differential seat angle during crank 2 starts, can continue to revolve the position and support lock via pulley 46, in the start comparatively smooth-going laborsaving, reach the effect that reduces noise, moreover the vehicle body of electrodynamic pump 3 and sewing machine body 1 is to be configured in parallel on the structure, die and to reduce body 1 ledge, so can increase overall aesthetic and make things convenient for cover to protect.
In sum, the design of the utility model on constructional device, it is more laborsaving smooth and easy that the compress pin is started, and effectively reduce noise, and it is specious to promote body.
