TWM629009U - Rotatable and fixable handle structure of band saw table - Google Patents

Abstract

The utility model relates to a handle structure that can be rotated and fixed for a saw table of a band saw. One end of a metal pipe body is integrally formed with a rotating handle with a metal fixing ring. The other end of the metal pipe body is sleeved with a plastic handle. There is a through hole in the center, and the metal fixing ring has a gap and is locked by the fixing piece; because the metal tube system is hollow, the overall weight is lighter and the manufacturing cost is lower, and the plastic handle is sleeved on the metal tube body. It provides friction force when the user holds it to avoid hand slippage, and also reduces the discomfort caused by the large temperature difference when the user holds it.

Description

The handle structure of the band saw machine saw table can be rotated and fixed

The present invention is a handle structure, especially a handle structure in which the saw table of a band saw machine can be rotatably fixed.

Referring to FIG. 4 and FIG. 5 , a rotary handle 30 conventionally applied to the saw table of a band saw is disclosed. The rotary handle 30 is a metal fixing ring 32 formed at one end of a metal connecting rod 31 , and the metal fixing ring 32 penetrates through the center. A through hole 321 is provided, a gap 322 is defined in the metal fixing ring 32, and the gap 322 of the metal fixing ring 32 is locked by a fixing member 323. The user can rotate the band saw machine by pulling the metal link 31. Spindle function.

However, since the metal connecting rod 31 is a solid iron casting, the characteristics of cast iron are that the manufactured metal connecting rod 31 has sand holes and is easy to break, and the metal connecting rod 31 is solid as a whole, in addition to the high manufacturing cost , the overall weight will also increase; in addition, when the user holds the metal connecting rod 31, the metal connecting rod 31 does not have an anti-slip effect, in addition to making it difficult for the user to hold, due to the high thermal properties of the metal material Therefore, the large temperature difference when the user holds the device will also cause discomfort to the hand.

Therefore, there is still room for improvement in the prior art in light of the above-mentioned deficiencies.

The present invention is a handle structure that can be rotatably fixed for a saw table of a band saw machine, including a rotating handle. The rotating handle is one end of a metal tube body integrally formed with a metal fixing ring, the The other end of the metal tube body is sleeved with a plastic handle, the metal tube system is hollow, a through hole is formed in the center of the metal fixing ring, a gap is opened in the metal fixing ring, and the gap is locked by a fixing piece.

With the above structure, since the metal tube system is hollow, the overall weight is lighter, and the manufacturing cost is also lower; furthermore, the plastic handle is sleeved on the metal tube body, which can increase the friction force when the user holds it and avoid the hand. It is slippery, and the user does not feel a large temperature difference when holding it, which can reduce the discomfort caused by the large temperature difference.

Wherein, the plastic handle is protruded with a plurality of anti-slip ridges, and each of the anti-slip ridges is spaced at a predetermined distance and arranged horizontally. The anti-slip ridges protruding above the plastic handle can further increase the friction force and increase the anti-slip effect when the user holds the handle, and the anti-slip ridges are arranged horizontally along the user's grip. The fingers are bent in the direction, so it can improve the comfort of the user when holding it.

Regarding the techniques, means and effects used in this creation, preferred embodiments are hereby described in detail in conjunction with the drawings. It is believed that the above-mentioned purposes, structures and features of this creation can be used to gain an in-depth and specific understanding.

Referring to Figure 1 and Figure 2, a handle structure of a band saw machine saw table can be rotatably fixed, including Including a rotating handle 10, the rotating handle 10 is a metal tube body 11 with one end integrally formed with a metal fixing ring 13, the other end of the metal tube body 11 is sleeved with a plastic handle 12, the metal tube body 11 is The metal fixing ring 13 is hollow, a through hole 131 is formed in the center of the metal fixing ring 13 , a gap 132 is defined in the metal fixing ring 13 , and the gap 132 of the metal fixing ring 13 is locked by a fixing member 14 . With the above structure, since the metal tube body 11 is hollow, the overall weight is lighter and the manufacturing cost is also lower, and furthermore, due to the poor thermal conductivity of the plastic handle 12, the user will not experience a large temperature difference when holding it. , can reduce the discomfort caused by the large temperature difference.

Continuing to refer to FIGS. 1 and 2 , the plastic handle 12 is protruded with a plurality of anti-slip protrusions 121 . Each of the anti-slip protrusions 121 is arranged horizontally and spaced at a predetermined distance. The plastic handle 12 is protruded with the anti-slip protrusions. The ridges 121 can further increase the frictional force and increase the anti-slip effect when the user holds the plastic handle 12 , and the anti-slip ridges 121 are arranged in the horizontal direction, which is more suitable for the user to hold the plastic handle 12 . The bending direction of the fingers can improve the comfort of the user when holding it.

Referring to FIG. 3 in conjunction with FIGS. 1 and 2 , it is disclosed that a rotating shaft 21 runs through the top of a base 22 , and a band saw 20 is disposed on the top of the base 22 .
