Abstract
The utility model belongs to the technical field of sewing machines, and specifically relates to a spring lock needle mechanism. The spring lock needle mechanism comprises a needle bar and a machine needle, wherein the lower end of the needle bar is sleeved with a clamping head, and a claw of the clamping head is sleeved outside the machine needle and acting on the machine needle; a hoop is sleeved outside the clamping head; an inner hole of the hoop can be matched with the appearance of the clamping head; a reset spring acting on the hoop is sleeved outside the needle bar; the reset spring makes the hoop generate the downward force to drive the claw of the clamping head to tightly clamp the machine needle. According to the spring lock needle mechanism provided by the utility model, the hoop is compressed by the reset spring and the tapered part is extruded to urge the clamping head to clamp the machine needle; the structure is simple, and convenient for the workers to dismount the machine needle; no potential safety hazard is formed, so that the spring lock needle mechanism is applicable to the sewing machines.
Description
Technical field:
The utility model belongs to sewing machine technique field, refers in particular to a kind of spring needle locking mechanism.
Background technology:
Sewing machines when work eedle need to firmly be fixed on shank, overcome the power in acupuncture action, make that eedle is unlikely to be dropped out or be shifted.What in flat seam machine, adopt at present is to be fixed by purl screw, in mounting or dismounting eedle, need to just can carry out by screwdriver.
On domestic sewing machine, use a kind of head sheet purl screw, workman can directly twist sheet head of screw with hand just can carry out the operation of dismounting eedle, but this sheet head of screw stretches out on shank limit, the reciprocating action that keyed shank is thousands of times per minute, sheet head of screw may be got to workman's hand, forms potential safety hazard.
Summary of the invention:
The purpose of this utility model is to provide the spring needle locking mechanism that a kind of workman of being convenient to carries out dismounting eedle, can not form potential safety hazard.
The utility model is achieved in that
A kind of spring needle locking mechanism, include shank and eedle, described shank lower end is arranged with dop, the catch jacket of dop is contained in outside eedle and acts on eedle, be set with cuff outward at dop, the endoporus of cuff can fit with the profile of dop, is set with the back-moving spring that acts on cuff at shank outward, and back-moving spring makes cuff produce the claw clamping eedle of downward power driving dop.
Above-mentioned dop is set in outside the minor diameter part of shank lower end, between minor diameter part and shank, be formed with step surface, minor diameter part between the upper plane of step surface and cuff is set with back-moving spring outward, and one end of back-moving spring holds out against on step surface, the other end holds out against in the upper plane of cuff.
Between above-mentioned cuff and minor diameter part for being threaded.
The upper plane of above-mentioned cuff is toward being arranged with and the annular groove of its coaxial line, and the other end of back-moving spring holds out against in annular groove.
The claw of above-mentioned dop is formed with pyramidal structure, and the diameter of pyramidal structure is up-small and down-big, in corresponding cuff, is formed with the bayonet socket matching with pyramidal structure, and cuff makes claw radially inside contract downwards to act on eedle eedle is clamped.
The outer surface of above-mentioned cuff is provided with annular groove, is provided with Overline ring in annular groove.
The advantage that the utility model is given prominence to is compared to existing technology:
The cuff of the present utility model spring compression that is reset, can push taper position, impels dop to clamp eedle, simple in structure, is convenient to workman and carries out dismounting eedle, can not form potential safety hazard.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is generalized section of the present utility model;
Fig. 3 is the schematic diagram of dop of the present utility model;
Fig. 4 is the schematic diagram of cuff of the present utility model.
The specific embodiment:
With specific embodiment, the utility model is further described below, referring to Fig. 1-4:
A kind of spring needle locking mechanism, include shank 1 and eedle 2, described shank lower end is arranged with dop 3, the claw 4 of dop 3 is sleeved on outside eedle 2 and acts on eedle 2, outside dop 3, be set with cuff 5, the endoporus of cuff 5 can fit with the profile of dop 3, is set with the back-moving spring 6 that acts on cuff 5 outside shank 2, and the claw 4 that back-moving spring 6 makes cuff 5 produce downward power driving dop 3 clamps eedle 2.
Above-mentioned dop 3 is set in outside the minor diameter part 7 of shank lower end, between minor diameter part 7 and shank 1, be formed with step surface 8, outside minor diameter part 7 between step surface 8 and the upper plane of cuff 5, be set with back-moving spring 6, one end of back-moving spring 6 holds out against on step surface 8, the other end holds out against in the upper plane of cuff 5.
Between above-mentioned cuff 5 and minor diameter part 7 for being threaded.
The upper plane of above-mentioned cuff 5 is toward being arranged with and the annular groove 9 of its coaxial line, and the other end of back-moving spring 6 holds out against in annular groove 9.Annular groove 9 can reduce rocking of back-moving spring 6, improves stability.
The claw 4 of above-mentioned dop 3 is formed with pyramidal structure, and the diameter of pyramidal structure is up-small and down-big, in corresponding cuff 5, is formed with the bayonet socket matching with pyramidal structure, and cuff 5 makes claw 4 radially inside contract downwards to act on eedle 2 eedle 2 is clamped.
The outer surface of above-mentioned cuff 5 is provided with annular groove 10, is provided with Overline ring 11 in annular groove 10.
When dress pin, cuff 5 is upwards pushed away, unclamp the claw 4 of dop 3, eedle 2 is inserted in dop 3 lower end centre bores 12, unclamp cuff 5, the claw 4 that cuff is reset the downward compression dop 3 of spring 6, pins eedle 2 to realize.
Above-described embodiment is only one of preferred embodiment of the present utility model; not limit practical range of the present utility model with this; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
