Description

Technical Field

[0001] The utility model relates to tools for removing and installing workpieces, in particular to an inlaid hexagonal wrench in a narrow space. Background Art

[0002] At present, on the braking cabinet of the existing HXD2 locomotive, due to the installation position limitation of the pressure sensor, other workpieces are installed around it. Without removing other workpieces, ordinary wrenches cannot disassemble and install the pressure sensor. There is an urgent need for a practical tool that can operate in a narrow space without removing other workpieces.

[0003] When applied to the situation where there are other workpieces around the installation position of the workpiece and the common wrench cannot reach the workpiece disassembly position due to the operation space limitation. A special tool is needed to disassemble and install such workpieces. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a special tool that can disassemble and install workpieces without removing other surrounding workpieces when there are other workpieces around the installation position of the workpiece and the ordinary wrench cannot reach the workpiece disassembly and installation position due to the operation space limitation.

[0005] To achieve the above object, the utility model provides an inlaid hexagonal wrench in a narrow space, which includes a wrench main body and a hexagonal wrench jaw arranged at one end of the wrench main body. The special feature is that the wrench main body has an embedded cavity extending along the axial direction; a ratchet wrench universal interface is arranged at the other end of the wrench main body.

[0006] A protective sleeve is sleeved outside the wrench main body.

[0007] An L-shaped limiting chute is arranged on the side wall of the protective sleeve. The first limiting screw arranged on the side wall at the other end of the wrench main body can enter the L-shaped limiting chute from the axial chute section of the L-shaped limiting chute, and when the first limiting screw is stuck in the circumferential chute section of the L-shaped limiting chute, the axial limit of the L-shaped limiting chute is realized.

[0008] Two axially symmetric second limiting screws are arranged on the side wall of the wrench main body adjacent to one end of the hexagonal wrench jaw to prevent the protective sleeve from falling off from this end, so as to limit the protective sleeve between the first limiting screw and the second limiting screw.

[0009] The ratchet wrench universal interface is a 1 / 2-inch ratchet wrench universal interface.

[0010] Advantages of the Utility Model

[0011] It can operate in a narrow space; adopting a coaxial rotation method, it can apply torque more concentratedly on the workpiece to be disassembled; it adopts a 1 / 2-inch ratchet wrench universal interface and can be used in conjunction with common tools on the market. The protective sleeve can protect the workpiece and prevent it from falling off during disassembly and installation. It solves the problem that the workpiece cannot be disassembled or installed due to insufficient operating space. Brief Description of the Drawings

[0015] Next, the technical solutions in the embodiments of the present patent will be clearly and completely described in conjunction with the drawings in the embodiments of the present patent. Obviously, the described embodiments are only a part of the embodiments of the present patent, rather than all the embodiments. Based on the embodiments of the present patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present patent.

[0016] As Figure 1 shown, the inlaid hexagon wrench in a narrow space provided in this embodiment (i.e., a hexagon wrench applicable to a narrow space) includes a wrench body 1 and a hexagon wrench jaw 2 provided at one end ( Figure 1 the lower end shown) of the wrench body 1. The wrench body 1 has an open inlaid cavity 3 extending along the axial direction, and the workpiece body to be pre-disassembled and installed can be wrapped in the inlaid cavity 3, thereby reducing the space requirement and well adapting to the application in a narrow space. And the pre-disassembled and installed workpiece is clamped by the hexagon wrench jaw 2. In this way, by adopting a coaxial rotation method, that is, the hexagon wrench provided in this embodiment rotates coaxially with the workpiece, torque can be applied more concentratedly on the workpiece to be disassembled. At the same time, at the other end of the wrench body 1, that is, Figure 1 the upper end shown, a ratchet wrench universal interface 4 is provided. Here, a 1 / 2-inch ratchet wrench universal interface is adopted, which can be used in conjunction with common tools on the market, improving the convenience and versatility of the application of this wrench and facilitating wide promotion.

[0017] At the other end of the wrench body 1, that is, Figure 1A protective sleeve 5 is provided at the upper end as shown. An L-shaped limiting chute 6 is provided on the side wall of the protective sleeve 5. A first limiting screw 7 provided on the side wall at the other end of the wrench body 1 can enter the L-shaped limiting chute 6 from the axial groove section of the L-shaped limiting chute 6. When the first limiting screw 7 is stuck in the circumferential groove section of the L-shaped limiting chute 6, axial limiting of the L-shaped limiting chute 6 is achieved. The settings of the protective sleeve 5, the first limiting screw 7, and the second limiting screw 8 are mainly used to protect the workpiece during the disassembly and assembly process. The specific protection process is that when disassembling the workpiece, rotate the protective sleeve 5 so that the first limiting screw 7 is placed in the axial groove section of the L-shaped limiting chute 6, so that the protective sleeve 5 is disengaged from the axial limiting of the first limiting screw 7 and slides down to the embedded cavity 3 of the wrench body 1, thereby forming a clamping sleeve for the workpiece accommodated in the open embedded cavity 3 to prevent the workpiece from falling off. And in order to ensure that the protective sleeve 5 effectively realizes the function of preventing the workpiece from falling off, in this embodiment, two axially symmetric second limiting screws 8 are provided on the side wall of the wrench body 1 near one end of the hexagonal wrench jaw 2 to prevent the protective sleeve 5 from falling off from this end, so as to limit the protective sleeve 5 between the first limiting screw 7 and the second limiting screw 8.

[0018] In summary, it is not difficult to see that the inlaid hexagonal wrench provided in the above embodiments can operate within a narrow workpiece; and by adopting a coaxial rotation method, the torque can be more concentratedly applied to the disassembled workpiece; when using a 1 / 2-inch ratchet wrench universal interface, it can be used in cooperation with common tools on the market, improving the versatility. By restricting the movement range of the protective sleeve, the workpiece can be effectively protected to prevent the workpiece from falling off during the disassembly and installation process. This inlaid hexagonal wrench well solves the problem that the workpiece cannot be disassembled and installed due to insufficient operating space.
