Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the tensioning device for the embroidery machine comprises a machine head body 100 and a plurality of tensioning assemblies 200, wherein the plurality of tensioning assemblies 200 are uniformly installed on the machine head body 100, each tensioning assembly 200 comprises an installation rod 210, a fixing piece 220 (referring to fig. 2), a movable piece 230 and a spring 240, the installation rod 210 is welded at one end of the machine head body 100 far away from a needle head 300, the fixing piece 220 can be welded at one end of the installation rod 210 close to the machine head body 100 and can also be sleeved on the installation rod 210, and the movable piece 230 and the spring 240 are coaxially sleeved with the installation rod 210. The movable plate 230 is obliquely arranged towards the direction far away from the fixed plate 220, two opposite sides of the fixed plate 220 extend outwards to form a bent extension plate 221, the extension plate 221 is bent towards the movable plate 230, and two ends of the extension plate 221 are provided with wire holes 222 for wires to pass through. The welding has a plurality of tighrening poles 110 on aircraft nose body 100, and tighrening pole 110 is located the both ends of a plurality of installation poles 210, install compressing blade 120 and nut 130 on the tighrening pole 110, compressing blade 120 passes tighrening pole 110, nut 130 with tighrening pole 110 threaded connection and with compressing blade 120 butt, compressing blade 120 corresponds a plurality of installation poles 210 and offers the through-hole 121 that supplies installation pole 210 one end to pass, the both ends of spring 240 respectively with movable plate 230 with compress blade 120 butt.

In order to facilitate the inspection of the pressing device by the worker, the mounting rod 210 includes a first half 211 and a second half 212, and ends of the first half 211 and the second half 212, which are far away from the handpiece body 100, are inclined in directions away from each other. After the worker removes the pressing sheet 120, the inclined first half portion 211 and the inclined second half portion 212 can resist the spring 240, so that the spring 240 is prevented from jumping and losing due to the action of the elasticity of the spring 240.

In order to adjust the single spring 240, the hole wall of the through hole 121 is threaded, an external threaded tube 400 is connected with the through hole 121 in a threaded manner, one end of the external threaded tube 400 abuts against the spring 240, and a hand-held part 500 is mounted at one end of the external threaded tube 400 far away from the movable piece 230, wherein the hand-held part 500 can be a handle or a plastic block, and is preferably a handle.

In order to make the relative position unanimous of pressing blade 120 both ends and anchorage bar 110, the scale 600 has all been welded at the both ends that aircraft nose body 100 is located pressing blade 120, the length direction and the aircraft nose body 100 of scale 600 are arranged perpendicularly, logical groove 610 has all been seted up along its length direction to two scales 600, pressing blade 120 corresponds the position extension of leading to groove 610 and has arranged directional piece 620, directional piece 620 and logical groove 610 sliding connection.

The implementation principle of the embodiment is as follows: when the tensioning device is used for tensioning the wire, the wire is wound around the mounting rod 210, so that the wire is positioned between the fixed plate 220 and the movable plate 230, and due to the elastic force of the spring 240, the movable plate 230 compresses the wire, so that the wire keeps a certain tensioning degree. When the tensioning force of the tensioning device needs to be adjusted, the nut 130 is screwed, and the spring 240 is compressed and extended along with the movement of the nut 130 under the action of the self elastic force, so that the tensioning force of the tensioning assemblies 200 can be adjusted. When it is required to adjust the tension of the single tension assembly 200, the male screw tube 400 corresponding to the tension assembly 200 is screwed, so that the male screw tube 400 compresses or releases the spring 240, thereby achieving adjustment of the tension of the single tension assembly 200.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
