Description

Technical Field

[0001] The invention relates to the field of installation and deviation correction tools, and in particular to a roller installation and deviation correction tool. Background Art

[0002] The handles of existing roller installation and correction tools are mostly rigid (such as metal) or nearly rigid (such as wooden sticks). When the roller is struck, part of the impact force received by the hammer part is transmitted to the operator's palm through the handle, causing the operator's palm and arm to vibrate. When the impact force is strong, or when the impact force is not strong but the striking is frequent, it will have an adverse effect on the operator's health. In the related art, people use bamboo as a handle to reduce the vibration and impact between the human hand and the handle, but the hammer with such a bamboo handle has low labor efficiency, is easily damaged, and is inconvenient to use. Summary of the invention

[0003] The present invention aims to solve the technical problems in the related technologies. To this end, an embodiment of the present invention proposes a flexible coupling, which utilizes the friction contact between a swingable friction part and a driven shaft to achieve transmission. The friction force can absorb part of the vibration and impact energy to make the transmission structure stable. At the same time, the friction can consume part of the mechanical energy, reduce the rotation speed of the driven shaft, avoid uncontrollable speed due to excessive rotation speed of the driving shaft, and ensure the safety of the transmission system.

[0004] The roller installation and deviation correction tool of the embodiment of the present invention includes a hammer and a handle, wherein the hammer and the handle are connected by a first elastic member, the handle includes a plurality of handle segments, adjacent handle segments are connected by a second elastic member, and the first elastic member and the second elastic member are both steel elastic members.

[0005] In the roller installation and deviation correction tool of the embodiment of the present invention, the hammer and the handle are connected by a first elastic member, the handle includes a plurality of handle segments, adjacent handle segments are connected by a second elastic member, and the first elastic member and the second elastic member are both steel elastic members, thereby, the vibration generated by the hammer striking will have part of its energy absorbed by the first elastic member before being transmitted to the handle, and then the energy of the vibration will be absorbed by the second elastic member when being transmitted between the handle segments, that is, the vibration will be weakened layer by layer during the transmission process, which significantly reduces the vibration and impact of the handle on the human arm when hammering, and compared with the solution of using flexible materials (such as bamboo) as handles to reduce vibration, the handle of the present application is not easy to be damaged and the tool has a long service life.

[0006] In some embodiments, the first elastic member is a steel elastic rod, a portion of which is inserted into the handle, and another portion of which is inserted into the hammer.

[0007] In some embodiments, the connecting end of the handle and the hammer is provided with a first threaded hole extending along its axial direction, and the side of the hammer facing the handle is provided with a second threaded hole opposite to the first threaded hole, and the steel elastic rod is threadedly fitted in the first threaded hole and the second threaded hole.

[0008] In some embodiments, the second elastic member is a metal helical spring tube.

[0009] In some embodiments, the metal coil spring tube is coated on the outer circumference of the handle segment.

[0010] In some embodiments, the plurality of handle segments include a front end handle and a rear end handle, wherein the front end handle is connected to the hammer, and the rear end handle is used for manual holding.

[0011] In some embodiments, a rubber vibration-damping layer is provided on the outer circumference of the front end handle and / or the outer circumference of the rear end handle.

[0012] In some embodiments, an anti-slip layer is provided on the outer peripheral surface of the tail handle.

[0013] In some embodiments, the anti-slip layer is an annular convex-concave pattern or a frosted surface.

[0014] In some embodiments, the tail handle includes a gripping section that is recessed inwardly relative to the remainder of the tail handle. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] like Figure 1 As shown, the roller installation and correction tool of the embodiment of the present invention includes a hammer 1 and a handle, the hammer 1 and the handle are connected by a first elastic member 2, the handle includes a plurality of handle segments, adjacent handle segments are connected by a second elastic member 3, and the first elastic member 2 and the second elastic member 3 are both steel elastic members.

[0020] It is understandable that the vibration generated by the hammer 1 striking will be transmitted to the handle through the first elastic member 2, and the vibration on the handle will be transmitted to the next handle section in sequence through the second elastic member 3. Since the hammer 1 and the handle and each handle section are connected by elastic members, the elastic members can be used to absorb vibration energy, significantly reducing the vibration and impact of the handle on the human arm when hammering. Compared with the solution of using flexible materials (such as bamboo) as handles to reduce vibration, the handle of the present application is not easy to be damaged and the tool has a long service life. In addition, the first elastic member 2 and the second elastic member 3 of the present application are both steel elastic members, which can ensure the rigid connection between the components during the vibration reduction.

[0021] In the roller installation and deviation correction tool of the embodiment of the present invention, the hammer 1 and the handle are connected by the first elastic member 2, the handle includes a plurality of handle sections, and the adjacent handle sections are connected by the second elastic member 3, and the first elastic member 2 and the second elastic member 3 are both steel elastic members, thereby, the vibration generated by the hammer 1 striking will be partially absorbed by the first elastic member 2 before being transmitted to the handle, and then the energy of the vibration will be absorbed by the second elastic member 3 when it is transmitted between the handle sections, that is, the vibration will be weakened layer by layer during the transmission process, which significantly reduces the vibration and impact of the handle on the human arm when hammering, and compared with the solution of using flexible materials (such as bamboo) as handles to reduce vibration, the handle of the present application is not easy to be damaged and the tool has a long service life.

[0022] Alternatively, if Figure 1 As shown, the first elastic member 2 is a steel elastic rod, part of which is inserted into the handle, and the other part is inserted into the hammer 1. Thus, the steel elastic rod can be hidden inside the handle and the hammer 1, and the connection structure is compact.

[0023] Optionally, the first elastic member 2 may also be a connecting member other than a steel elastic rod, which is not limited here.

[0024] Furthermore, the connection end of the handle and the hammer 1 is provided with a first threaded hole extending along its axial direction, and the side of the hammer 1 facing the handle is provided with a second threaded hole opposite to the first threaded hole, and the steel elastic rod is threadedly engaged in the first threaded hole and the second threaded hole. In other words, the two ends of the steel elastic rod are respectively screwed into the threaded holes of the hammer 1 and the handle by threads, which is convenient to disassemble and reliable in connection.

[0025] Preferably, the second elastic member 3 is a metal helical spring tube.

[0026] Furthermore, the metal spiral spring tube is coated on the outer peripheral surface of the handle section. Figure 1As shown, the multiple handle sections include a front handle 41 and a rear handle 42, the front handle 41 is connected to the hammer 1, and the rear handle 42 is used for manual holding, wherein the rear end of the front handle 41 extends into the front end of the metal coil spring tube, and the front end of the rear handle extends into the rear end of the metal coil spring tube, and the cooperation between the metal coil spring tube and the handle section has a certain assembly limiting effect.

[0027] Furthermore, a rubber vibration-damping layer is provided on the outer circumference of the front handle 41 and / or the outer circumference of the rear handle 42. Preferably, the outer circumferences of the front handle 41 and the rear handle 42 are both coated with a rubber vibration-damping layer, which can improve the comfort of holding by a human hand on the one hand, and can further reduce vibration by using the rubber vibration-damping layer on the other hand.

[0028] In some embodiments, an anti-slip layer 5 is provided on the outer peripheral surface of the tail end handle 42 to facilitate manual holding, avoid slipping of the hands due to the recoil force, and improve operational safety.

[0029] Optionally, the anti-slip layer 5 is an annular convex-concave pattern or a frosted surface.

[0030] It should be noted that the anti-slip layer 5 is not limited to the annular convex-concave pattern or frosted surface as mentioned above, as long as it can achieve anti-slip effect, and no limitation is made here.

[0031] In some embodiments, the tail handle 42 includes a gripping section, and the gripping section is recessed inwardly relative to the rest of the tail handle 42.
