[0006] Further, an annular groove is formed on the back surface of the outer disc.

[0007] Further, the number of the spokes is three.

[0008] Further, each spoke includes a flat joint part and an inclined joint part. The flat joint part and the inclined joint part are integrally formed. The flat joint part is connected to the outer disc, and the inclined joint part is connected to the central shaft sleeve.

[0009] Further, a straight groove is provided on the back of each spoke.

[0010] Further, the central shaft sleeve includes a strengthening part and a connecting part. The strengthening part and the connecting part are integrally formed. The wall thickness of the strengthening part is greater than that of the connecting part; the strengthening part is connected to the spokes.

[0011] The second object of the utility model is to provide a water jet loom console, which solves the problems of large weight and low strength of the handwheel used on the water jet loom console.

[0012] In order to achieve the above object, the technical solution adopted by the utility model is:

[0013] A water jet loom console includes a console body and the handwheel described in the above embodiment. The handwheel is connected to the console body.

[0014] The third object of the utility model is to provide a water jet loom, which solves the problem of short service life of the handwheel on the console.

[0015] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0016] A water jet loom, comprising a machine body and the water jet loom console described in the above embodiment, and the water jet loom console is installed on the machine body.

[0017] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0018] By providing grooves on the outer disc and the spokes, the present utility model reduces the weight of the handwheel, reduces the use of raw materials, and lowers the manufacturing cost. Both sides of the groove are provided with groove walls, which can still increase the strength of the handwheel. The handwheel is installed on the water jet loom console, reducing the force for the technical worker to operate the handwheel and improving the working comfort of the technical worker. The strength of the handwheel on the water jet loom console is increased, thereby extending the service life of the water jet loom. The present utility model not only reduces the weight of the handwheel but also increases its strength. Description of the Drawings

[0022] Embodiment 1

[0023] As Figures 1 to 3 shown, a handwheel includes an outer disc 1 and a central shaft sleeve 2. The central shaft sleeve 2 is connected to the outer disc 1 through a plurality of spokes 3. The outer disc 1 is provided with through holes 4, and the central shaft sleeve 2 is provided with oil injection holes 5. The central shaft sleeve 2 is connected to the water jet loom, and the through holes 4 are connected to the control handle. The operator rotates the handwheel through the control handle. The central shaft sleeve 2 is connected to the outer disc 1 through three spokes 3, reducing the manufacturing cost of the outer disc 1 and saving raw materials.

[0024] The back surface of the outer disc 1 has an annular groove 6. Both sides of the annular groove 6 have groove walls 7, and the groove walls 7 on both sides can provide support force for the outer disc 1, improving the strength of the outer disc 1. The spoke 3 includes a flat joint part 8 and an inclined joint part 9. The flat joint part 8 and the inclined joint part 9 are integrally formed. The flat joint part 8 is connected to the outer disc 1, and the inclined joint part 9 is connected to the central shaft sleeve 2. The spoke 3 makes the outer disc 1 and the central shaft sleeve 2 located in different planes, distributes the force received by the outer disc 1 to different planes, reduces the force on the outer disc 1 and the central shaft sleeve 2, and enhances the strength of the outer disc 1 and the central shaft sleeve 2. The back of the spoke 3 is provided with a straight groove 11, and both sides of the straight groove 11 have groove walls 7, and the groove walls 7 can increase the strength of the spoke 3. The central shaft sleeve 2 includes a strengthening part 12 and a connecting part 13. The strengthening part 12 and the connecting part 13 are integrally formed, and the wall thickness of the strengthening part 12 is greater than that of the connecting part 13; the strengthening part 12 is connected to the spoke 3, increasing the thickness of the strengthening part, which can improve the strength of the central shaft sleeve 2 and extend the service life of the central shaft sleeve 2.
