Description

Technical Field

[0001] This utility model belongs to the field of processing fixture technology, and specifically relates to a combination marking wrench. Background Technology

[0002] In fields such as machinery maintenance, equipment assembly, and industrial production, the tightening of bolts and nuts is an extremely common operation. During the tightening process, to ensure the strength and safety of the connection, it is usually necessary to perform torque testing and marking to facilitate subsequent inspection and maintenance, and to promptly detect any loosening.

[0003] Currently, most marking tools and wrenches on the market are independent. Operators need to first use the wrench to complete the tightening or re-inspection work, and then use a marking pen or other marking tools to mark the tightened bolts and nuts. This operation method is not only cumbersome and inefficient, but also prone to omissions in marking during multiple operation transitions. Therefore, there is an urgent need to design a simple combined marking wrench that can complete marking simultaneously with wrench use to solve the problems existing in the current technology.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1

[0023] refer to Figures 1 to 5The combined marking wrench described in this embodiment includes a wrench 1, which includes a handle 11 and a mounting part 12. The mounting part 12 has a mounting hole 13, and a connector 2 is detachably inserted into the mounting hole 13. A tightening rod 3 is mounted below the connector 2, and an ink sac 4 can be selectively mounted above the connector 2. The ink sac 4, the connector 2, and the tightening rod 3 have coincident axes and a through hole along the axial direction for storing absorbent cotton 5, which contains ink or pigment.

[0024] Connector 2 installs the ink cartridge 4 and the tightening lever 3 onto the wrench 1. During operation, the tightening lever 3 is aligned with the bolt and tightened. During tightening, the absorbent cotton 5 contacts the bolt, marking the area larger than the bolt to prevent repeated tightening or missed markings. It is worth noting that the ink cartridge 4 increases the capacity of the absorbent cotton 5, thereby increasing ink storage, extending the marking time, and reducing the frequency of ink replenishment. The ink cartridge 4 is not a necessary feature. Different tightening levers 3 can be used for bolts of different shapes to increase practicality.

[0025] Preferably, wrench 1 is a re-inspection torque wrench.

[0026] The connector 2 includes an integrally formed upper connecting ring 21, a mounting ring 22, and a lower connecting ring 23. The upper connecting ring 21 is detachably and fixedly connected to the ink sac 4. The mounting ring 22 is inserted into the mounting hole 13. The lower connecting ring 23 is detachably and fixedly connected to the turning rod 3. The connector 2 has a through hole along the axis through the upper connecting ring 21, the mounting ring 22, and the lower connecting ring 23 for placing the absorbent cotton 5.

[0027] Preferably, the mounting ring 22 is gear-shaped and matches the pawl of the recheck torque wrench to accommodate the recheck torque function of the wrench 1.

[0028] The outer diameter of the upper connecting ring 21 is larger than the inner diameter of the mounting hole 13.

[0029] The rotating rod 3 includes an integrally formed receiving tube 31 and a rotating tube 32. The receiving tube 31 is detachably and fixedly connected to the lower connecting ring 23. The receiving tube 31 has a through hole for placing the absorbent cotton 5 along the axis. The rotating tube 32 has an insertion hole 33 along the axis. The insertion hole 33 corresponding to different rotating rods 3 has a different cross-sectional shape. The insertion hole 33 is connected to the through hole for placing the absorbent cotton 5.

[0030] It is worth noting that the diameter of the insertion hole 33 is smaller than the through hole for placing the absorbent cotton 5, so as to form a step to block the absorbent cotton 5. The absorbent cotton 5 leaves a protruding part that extends into the twisting tube 32 to ensure the smoothness of the marking.

[0031] Preferably, the inner wall of the receiving tube 31 is provided with a threaded hole, and the corresponding outer wall of the lower connecting ring 23 is provided with a thread.

[0032] Preferably, the outer diameter of the rotating rod 3 is smaller than the inner diameter of the mounting hole 13.
