DETAILED DESCRIPTION

[0023] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] It is worth noting that the directional words such as "upper" and "lower" involved in this article are all relative to the viewing angle of the drawings and are only for the convenience of description and cannot be understood as limitations on the technical solution.

[0025] like Figure 1 As shown, a tool for adjusting the opening degree of the entrance guide of a rolling mill comprises a straight rod 1 and a bent rod 2, wherein the bent rod 2 is bent in an arc shape, one end of the bent rod 2 is connected to one end of the straight rod 1, and the other end of the bent rod 2 away from the straight rod 1 is a first connecting end 21, which is adapted to the adjustment hole of the guide.

[0026] The utility model is similar to a rod with one end bent. Generally, the first connection end 21 of the bent rod 2 is inserted into the adjustment hole, and then the guide is adjusted by pushing or pulling the straight rod 1. In this process, a force point is formed at the contact point between the first connection end 21 of the bent rod 2 and the adjustment hole, which is the force point formed by a conventional crowbar when in use. In addition, the bending part of the bent rod 2 also forms a second force point. When force is applied from the straight rod 1, the force direction is changed by the bent rod 2, and the tool as a whole is not easy to fall out of the adjustment hole.

[0027] Furthermore, the straight rod 1 is detachably connected to the curved rod 2. The detachable connection structure facilitates changing the length of the entire tool to adapt to different usage scenarios. For example, the straight rod 1 is provided with an engaging groove 12 at one end facing the curved rod 2, and the curved rod 2 is provided with an engaging piece 22 at one end facing the straight rod 1. The engaging piece 22 is embedded in the engaging groove 12 and fixed. The depth of the engaging groove 12 is less than or equal to the length of the engaging piece 22, so as to realize the detachable connection between the straight rod 1 and the curved rod 2.

[0028] Furthermore, the other end of the straight rod 1 is a second connecting end 11, which is adapted to the adjustment hole.

[0029] The significance of adjusting the overall length of the tool is that the utility model acts like a lever when in use, and increasing the length of the tool is conducive to increasing the lever arm to achieve a labor-saving effect. In addition, adjusting the length of the tool can also enable the tool to be used in a narrow environment. For example, the straight rod 1 is removed, and the engaging member 22 plays the role of the straight rod 1, and the guide can be adjusted only by the bent rod 2 in a relatively narrow space, or the bent rod 2 is removed, and the second connecting end 11 of the straight rod 1 is inserted into the adjustment hole, and the guide can be adjusted only by the straight rod 1, that is, the function is similar to that of an existing crowbar.

[0030] Specifically, the utility model proposes the following two feasible structures:

[0031] like Figure 2 As shown, in one embodiment, the depth of the engaging groove 12 is equal to the length of the engaging member 22, and the side wall of the engaging groove 12 is provided with multiple groups of latch holes penetrating the straight rod 1 along the length direction of the straight rod 1, and the engaging member 22 is provided with a latch fixing hole adapted to the latch hole, and the engaging member 22 is inserted into the engaging groove 12, so that the latch fixing hole is aligned with one group of latch holes, and the locking latch member 13 passes through the latch fixing hole and the corresponding latch hole to lock the straight rod 1 and the bent rod 2. This is a quick-release structure, and the length of the entire tool can be changed by adjusting the length of the engaging member 22 extending into the engaging groove 12.

[0032] It should be noted that the function of the locking latch member 13 is to prevent the straight rod member 1 from slipping out along its length direction. A set of latch through holes includes two latch through holes, which are respectively located on the two opposite side walls of the fitting groove 12, and the locking latch member 13 can penetrate the straight rod member 1. Preferably, the locking latch member 13 is "T" shaped, and the end of the locking latch member 13 that passes through the straight rod member 1 is provided with an external thread surface, which is connected to the locking nut 14 to lock the straight rod member 1 and the curved rod member 2.

[0033] Furthermore, the inner space of the embedding groove 12 is in the shape of a cuboid, and the embedding member 22 is in the shape of a cuboid, that is, when the embedding member 22 is embedded in the embedding groove 12, the rotation of the bent rod member 2 is restricted.

[0034] like Figure 3 As shown, in one embodiment, the space inside the embedding groove 12 is cylindrical, the embedding piece 22 is cylindrical, the inner wall of the embedding groove 12 is provided with an internal threaded surface, the outer side surface of the embedding piece 22 is provided with an external threaded surface, the embedding piece 22 is threadedly connected to the embedding groove 12, and an adjusting nut 15 is provided outside the embedding piece 22, and the adjusting nut 15 is in contact with the straight rod member 1 to lock the straight rod member 1 and the bent rod member 2.

[0035] It is easy to understand that when adjusting the tool length, first loosen the adjusting nut 15 and move it away from the straight rod 1, then rotate the straight rod 1 or the bent rod 2 to change the length of the engaging member 22 in the engaging groove 12, and after the adjusted length is determined, turn the adjusting nut 15 toward the straight rod 1 until the adjusting nut 15 is locked to achieve locking of the straight rod 1 and the bent rod 2. More preferably, the sum of the depth of the engaging groove 12 and the thickness of the adjusting nut 15 is equal to the length of the engaging member 22.

[0036] In the present invention, the tool for adjusting the opening of the rolling mill entrance guide also includes a connecting piece 3 and a locking bolt 31. Figure 4-5 As shown, the outer side of the straight rod 1 is provided with a plurality of threaded holes, the connecting member 3 is arranged outside the straight rod 1 and is provided with a first connecting hole adapted to the threaded hole, and the connecting member 3 is also preset with a plurality of second connecting holes 32 for connecting with external equipment.

[0037] When a larger force is needed to push the guide or to fine-tune the guide, it can be achieved through external equipment such as hydraulic cylinders and electric cylinders. It should be noted that the utility model does not involve the arrangement or improvement of external equipment. The function of the connector 3 is to connect the straight rod 1 with the external equipment. For example, the connector 3 can be a flat plate to increase the connection surface between the straight rod 1 and the external equipment. It is easy to understand that when the external equipment is not needed, the connector 3 and the locking bolt 31 are removed to avoid affecting the manual adjustment.

[0038] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
