Abstract

The utility model discloses a needle blade connected assembly. The needle blade connected assembly comprises a lower connection needle (1) connected to the inner portion of a pattern bit clamping groove in an inserted mode and a lower needle knife (2) connected with the lower connection needle (1). One side of the upper end of the lower connection needle (1) extends upwards to form a sliding limiting piece (3) attached to the side face of the lower needle knife (2), and a limiting step which is perpendicular to the sliding limiting piece (3) is formed on the end portion of the lower connection needle (1). When the needle blade connected assembly retracts, the bottom end of the lower needle knife (2) abuts against the limiting step. The needle blade connected assembly is simple in structure and convenient to refit. By the adoption of the needle blade connected assembly, on the premise that the existing swinging amplitude and the existing swinging space are not influenced, the rising height of the lower needle knife can be greatly increased in the process of work, the height difference can be increased, and the lengths of coils can be increased on the premise that work of the lower coil and the middle coil is not influenced.

Description

A kind of pin blade coupling assembling

Technical field

The utility model relates to jacquard processing and manufacturing field, is specifically related to a kind of pin blade coupling assembling.

Background technology

Referring to Fig. 1, in the market in the crochet hook assembly on common jacquard under to connect pin and lower pin cutter be to adopt buckle clamping fixing all-in-one-piece mostly, and in the process of using due to be plugged on pattern bit in draw-in groove under connect pin because of the amplitude of fluctuation limited space, cause the amplitude of its rising less, therefore corresponding loop length is also less, can only do middle low coil.

Summary of the invention

The utility model purpose is to provide under a kind of prerequisite not affecting existing amplitude of fluctuation and space, significantly increased the height that time pin cutter rises in the process of work, and increased the pin blade coupling assembling of height fall, it in low coil work, has increased the length of coil in not affecting.

In order to solve existing problem in background technology, it comprise be plugged in the pattern bit draw-in groove under the lower pin cutter 2 that connects pin 1 and be attached thereto, under described, connect on a side direction of pin 1 upper end extend the lower pin cutter of laminating 2 sides slide spacing 3, and under connect pin 1 end form one perpendicular to the limited step that slides spacing 3, during withdrawal, the bottom of described lower pin cutter 2 withstands on limited step.

Owing to having adopted above technical scheme, the utlity model has following beneficial effect: simple in structure, repacking is convenient, under the prerequisite that does not affect existing amplitude of fluctuation and space, significantly increased the height that time pin cutter rises in the process of work, increased height fall, and in low coil work, increased the length of coil in not affecting.

The accompanying drawing explanation

In order to be illustrated more clearly in the utility model, below in conjunction with accompanying drawing, embodiment is briefly described.

Fig. 1 is the structural representation in the utility model background technology;

Fig. 2 is structural representation of the present utility model;

Fig. 3 is the contrast schematic diagram of prior art scheme in the specific embodiment;

Fig. 4 is the contrast schematic diagram of technical scheme in this specific embodiment.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, the accompanying drawing below in conjunction with in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment.

Referring to Fig. 2, this specific embodiment is to be achieved by the following technical solutions, it comprise be plugged in the pattern bit draw-in groove under the lower pin cutter 2 that connects pin 1 and be attached thereto, under described, connect on a side direction of pin 1 upper end extend the lower pin cutter of laminating 2 sides slide spacing 3, and under connect pin 1 end form one perpendicular to the limited step that slides spacing 3, during withdrawal, the bottom of described lower pin cutter 2 withstands on limited step; When disengagement is not separated in the path, the road of pin up and down at the angle of ensureing, make to slide spacing 3 and the process that moves up and down in the syringe needle tray of lower pin cutter 2 in can not stick up outward; Instantly pin cutter 2 will be crossed to slide and can up shift out lower pin cutter 2 onto the pin position according to angular pin road, mountain at spacing 3 o'clock, then plays pin cutter 2 to rise voluntarily along the respective needle road, under connect pin 1 and can continue to rise, thereby connect the short purpose of pin 1 movement travel under final the realization.

Do further contrast below in conjunction with the technique effect of technical scheme and prior art in pair this specific embodiment of Fig. 3-4:

Referring to Fig. 3, due to be plugged in the pattern bit draw-in groove under connect that mode that pin adopts clamping is connected with lower pin cutter and fixing all-in-one-piece, its upper and lower drop only limits to the degree of depth of draw-in groove on pattern bit, so drop a is less, only can coordinate and produce middle low coil with three angular components that become mildewed down.

Referring to Fig. 4, due to be plugged in the pattern bit draw-in groove under connect pin 1 and adopt spacing 3 modes of fitting with lower pin cutter 2 that slide to be connected, additionally increase by one and slided spacing 3 height, therefore make the drop b of lower pin cutter 2 obtain further raising, make it not only can coordinate and produce middle low coil with three angular components that become mildewed down, can also coordinate and produce longer coil with three angular components under undercoat.

Owing to having adopted above technical scheme, this specific embodiment has following beneficial effect: simple in structure, repacking is convenient, under the prerequisite that does not affect existing amplitude of fluctuation and space, significantly increased the height that time pin cutter rises in the process of work, increased height fall, and in low coil work, increased the length of coil in not affecting.

Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, its technical scheme that still can put down in writing aforementioned each embodiment is modified, or part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.

Claims (1)

1. a pin blade coupling assembling, it comprise be plugged in the pattern bit draw-in groove under the lower pin cutter (2) that connects pin (1) and be attached thereto, it is characterized in that under described connecing slide spacing (3) of extending the lower pin cutter (2) of laminating side on a side direction of pin (1) upper end, and under connect pin (1) end form the limited step of spacing perpendicular to sliding (3), during withdrawal, the bottom of described lower pin cutter (2) withstands on limited step.
