Description

Technical Field

[0001] This utility model relates to the field of advanced manufacturing and automation technology, specifically a portable torque tool. Background Technology

[0002] Torque tools play a crucial role in industrial production, automotive repair, mechanical assembly, and many other fields, serving as indispensable tools for precise operations. These tools ensure that fasteners such as screws and bolts are properly tightened to specified torque values, thereby guaranteeing equipment safety and reliability. Whether used for large-scale operations on production lines, meticulous vehicle maintenance in auto repair shops, or handling precision components during mechanical assembly, torque tools provide the necessary support to ensure efficient and accurate work.

[0003] Traditional torque tools often have limited functionality and numerous inconveniences. Regarding torque head replacement, many traditional tools employ complex connection methods, requiring the use of various specialized tools for disassembly and installation. This results in significant time and effort wasted when frequently changing torque heads to suit different tasks, severely impacting work efficiency. For example, in automotive repair shops, technicians may need to tighten bolts on different parts of the engine, chassis, etc., within a short period. These bolts may require torque heads with different torque values. Inconvenient torque head replacement will delay the repair process. Furthermore, traditional torque tools lack effective portable designs. They are typically simply placed in tool bags or toolboxes. In special working environments, such as working at heights or in confined spaces, workers find it difficult to easily access and store tools. Without dedicated carrying devices, tools are prone to slipping or being lost, causing not only economic losses but also potential safety hazards to personnel or equipment below.

[0012] A mounting plate is provided, with a locking groove on the mounting plate that matches the locking block on the bottom of the fixed disc. Quick locking and unlocking are achieved through the cooperation of the locking rod and the locking hole. The locking rod is held inserted into the locking hole by the magnetic attraction of the magnetic block and magnetic head, ensuring the locking block is stably engaged within the locking groove.

[0013] Preferably, the mounting plate has a locking groove that matches the locking block. Fixed mounting blocks are fixedly installed on both outer walls of the mounting plate. A rectangular groove is opened inside the fixed mounting block. A limiting circular block opening is opened on the outer wall of the fixed mounting block.

[0015] This invention provides a portable torque tool. It has the following advantages:

[0016] (1) This utility model drives the threaded rod to rotate in the threaded sleeve by rotating the rotating wheel. Since the threaded rod is threadedly connected to the threaded connection hole on the rectangular mounting block, and the rectangular mounting block is engaged with the rectangular slot at the bottom of the fixed block, the rotating block can slide smoothly up and down in the mounting opening. This structural design makes the replacement of the torque head extremely convenient. The operator only needs to rotate the rotating wheel to easily remove the old torque head and quickly install the new torque head. Due to its flexible installation structure, the torque head replacement installation part can be compatible with a variety of torque heads of different specifications, shapes and types, such as hexagonal head, Torx head, square head, etc., which makes the portable torque tool able to meet the needs of different industries and different work tasks.

[0017] (2) This utility model achieves quick installation and removal of torque tools on the quick-release buckle carrying part through the cooperation of the locking block and the locking groove on the mounting plate, as well as the locking mechanism of the locking rod and the locking hole. The operator only needs to operate the handwheel to rotate the rectangular block in the circular groove of the locking block, which drives the magnetic block to engage or disengage with the magnetic head on the locking rod.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals 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 intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1:

[0026] A preferred embodiment of the portable torque tool provided by this utility model is, for example... Figure 1-4 As shown: A portable torque tool includes a handle 1, a torque head replacement mounting part 3, and a quick-release buckle carrying part 4. Rubber textured strips 2 are fixedly installed at equal intervals on the top and bottom outer walls of the handle 1. The torque head replacement mounting part 3 is located at one end of the handle 1. The quick-release buckle carrying part 4 is located at the other end of the handle 1.

[0027] The torque head replacement mounting part 3 specifically includes: a mounting port 311, which is opened at one end of the handle 1; a round port 312, which is opened at the other end of the handle 1; and a fixing block 317, which is fixedly installed on the top of the handle 1.

[0028] A threaded sleeve 318 is fixedly installed on the top of the fixing block 317. A threaded rod 319 is threadedly connected inside the threaded sleeve 318. A rotating wheel 3111 is fixedly installed on one end of the threaded rod 319. The other end of the threaded rod 319 moves through the top outer wall of the fixing block 317 and extends into the interior of the mounting port 311.

[0029] The mounting port 311 has a sliding connection to a rotating block 314. The bottom outer wall of the fixed block 317 has a rectangular slot. The top of the rotating block 314 has a fixed rectangular mounting block 315. The rectangular mounting block 315 has a threaded connection hole 316. The rectangular mounting block 315 engages with the rectangular slot. The other end of the threaded rod 319 is threadedly connected to the threaded connection hole 316. The bottom of the rotating block 314 has a fixed torque head 313.

[0030] In this embodiment, rotating the wheel 3111 causes the threaded rod 319 to rotate. Since the threaded rod 319 is threadedly connected to the threaded connection hole 316 on the rectangular mounting block 315, and one end of the threaded rod 319 moves through the top outer wall of the fixing block 317 and extends into the interior of the mounting port 311, as the threaded rod 319 rotates, it gradually pulls the torque head 313 toward the fixing block 317, thereby achieving a firm installation of the torque head 313 at one end of the handle 1. This structural design makes the replacement of the torque head extremely convenient. The operator only needs to rotate the wheel to easily remove the old torque head and quickly install the new torque head. Due to its flexible installation structure, this torque head replacement installation part can be compatible with a variety of torque heads of different specifications, shapes and types.

[0031] Example 2:

[0032] Based on Embodiment 1, a preferred embodiment of the portable torque tool provided by this utility model is as follows: Figure 1-4 As shown: The quick-release buckle carrying part 4 specifically includes: a connecting rope ring 412, which is set inside the round opening 312; a mounting plate 4112, which is set at the other end of the handle 1; a fixing plate 411 is fixedly connected to the connecting rope ring 412; a fixing disc 413 is fixedly installed on one outer wall of the fixing plate 411; a round through-hole 414 is opened on the fixing disc 413; a locking block 415 is fixedly installed at the bottom of the fixing disc 413; a round groove is opened inside the locking block 415, which is connected to the round through-hole 414; and a locking hole 416 is opened on the outer wall of the locking block 415.

[0033] The card hole 416 is connected to the circular groove. The inner wall of the circular opening 414 is rotatably connected to a rotating circular block 419. A rotating handwheel 4111 is fixedly installed on the top of the rotating circular block 419. A rectangular block 417 is fixedly connected to the bottom of the rotating circular block 419. A positioning hole is opened at the bottom of the rectangular block 417. An installation circular opening is opened on both outer walls of the rectangular block 417. A magnetic block 418 is fixedly installed inside the installation circular opening. The rectangular block 417 is set inside the circular groove, and a card plate 4112 is installed.

[0034] The mounting plate 4112 has a locking groove that matches the locking block 415. The mounting plate 4112 has a fixed mounting block 4115 fixedly installed on both outer walls. The fixed mounting block 4115 has a rectangular groove inside. The outer wall of the fixed mounting block 4115 has a limiting round block opening. The limiting round block opening is slidably connected to the inside of the limiting round block opening. The outer wall of the limiting round block 4117 has a locking rod 4116 fixedly installed. The other end of the locking rod 4116 moves through the inner wall of the rectangular groove and extends into the locking groove. The locking rod 4116 matches the locking hole 416.

[0035] A magnetic suction head is fixedly installed at the other end of the locking rod 4116. A positioning rod 4114 is fixedly installed on the inner wall of the locking groove. A rectangular block 417 is movably sleeved on the outer wall of the positioning rod 4114 through the positioning hole. A return spring 4118 is movably sleeved on the outer wall of the locking rod 4116. One end of the return spring 4118 is fixedly connected to the limiting round block, and the other end of the return spring 4118 is fixedly connected to the inner wall of the rectangular groove. A connecting plate is fixedly installed on the outer wall of the mounting plate 4112. An elastic nylon belt 4113 is fixedly connected to the other end of the connecting plate. A buckle mounting hole is opened on the elastic nylon belt 4113. The magnetic suction head and the magnetic block 418 are attracted to each other.

[0036] In this embodiment, the connecting rope loop 412 is first passed through the circular opening 312, so that the fixing plate 411 is positioned at the other end of the handle 1. At this time, the fixing disc 413 and the locking block 415 below it are aligned with the mounting plate 4112. Then, the locking block 415 is inserted into the engaging groove of the mounting plate 4112. At this time, the positioning rod 4114 will be inserted into the positioning hole at the bottom of the rectangular block 417 to initially position the rectangular block 417. Next, the rotating handwheel 4111 is turned to drive the rotating block 419 to rotate, thereby causing the rectangular block 417 to rotate in the circular groove of the locking block 415. When the rectangular block 417 rotates, the magnetic blocks 418 installed in the circular openings on both sides of its outer wall will gradually approach the magnetic head on the locking rod 4116. Due to the magnetic attraction, When the magnetic block 418 is used, it attracts the magnetic head, causing the lever 4116 to move into the rectangular slot against the elastic force of the return spring 4118. When the rectangular block 417 rotates to a certain angle, the magnetic block 418 and the magnetic head are firmly attracted. At this time, under the combined action of the magnetic attraction and the return spring 4118, the other end of the lever 4116 is inserted into the locking hole 416, thus locking the lever 415 with the mounting plate 4112. This completes the installation of the torque tool on the quick-release buckle carrying part, making it easy to fix the tool on the mounting plate 4112 or remove it from it. The torque tool can be quickly hung on or removed from the body, greatly improving work efficiency and reducing the time and effort wasted due to the inconvenience of taking and putting away the tool.

[0037] Working principle: When using:

[0038] Step 1: First, confirm that the torque head 313 to be installed and all components of the torque head replacement and installation part 3 are in an installable state, that is, the installation port 311, the round port 312, the fixing block 317 and other components are undamaged and clean, and ensure that the threaded rod 319 can rotate smoothly.

[0039] Step 2: Align the rectangular mounting block 315 fixed at the top of the torque head 313 with the rectangular slot opened on the bottom outer wall of the fixing block 317, and then push the rectangular mounting block 315 along the slot so that the rectangular mounting block 315 engages with the rectangular slot. At this time, the torque head 313 is in an adjustable position in the mounting port 311 through the rotating block 314 at its top.

[0040] Step 3: Rotate the rotating wheel 3111. The rotating wheel 3111 drives the threaded rod 319 to rotate. Since the threaded rod 319 is threadedly connected to the threaded connection hole 316 on the rectangular mounting block 315, and one end of the threaded rod 319 moves through the top outer wall of the fixing block 317 and extends into the interior of the mounting port 311, as the threaded rod 319 rotates, it will gradually pull the torque head 313 towards the fixing block 317, thereby achieving a firm installation of the torque head 313 at one end of the handle 1.

[0041] Step 4: First, pass the connecting rope loop 412 through the round opening 312, so that the fixing plate 411 is in a suitable position at the other end of the handle 1. At this time, the fixing disc 413 and the locking block 415 below it are aligned with the mounting plate 4112. Then, insert the locking block 415 into the engaging groove of the mounting plate 4112. At this time, the positioning rod 4114 will be inserted into the positioning hole at the bottom of the rectangular block 417, and the rectangular block 417 will be initially positioned. Next, turn the rotating handwheel 4111 to drive the rotating block 419 to rotate, thereby causing the rectangular block 417 to rotate in the round groove of the locking block 415. When the rectangular block 417 rotates, its two sides The magnetic block 418 inside the outer wall mounting round opening will gradually approach the magnetic head on the lever 4116. Due to the magnetic attraction, the magnetic block 418 will attract the magnetic head, causing the lever 4116 to overcome the elastic force of the return spring 4118 and move into the rectangular groove. When the rectangular block 417 rotates to a certain angle, the magnetic block 418 and the magnetic head are firmly attracted. At this time, under the combined action of the magnetic attraction and the return spring 4118, the other end of the lever 4116 is inserted into the card hole 416, realizing the locking of the card block 415 and the mounting plate 4112, thus completing the installation of the torque tool on the quick-release buckle carrying part.

[0042] Step 5: First, rotate the handwheel 4111 in the opposite direction to drive the rotating block 419 to rotate in the opposite direction, thereby causing the rectangular block 417 to rotate in the opposite direction within the circular groove of the locking block 415. When the rectangular block 417 rotates in the opposite direction, the magnetic blocks 418 installed in the circular openings on both sides of its outer wall will gradually move away from the magnetic head on the locking rod 4116, and the magnetic attraction will weaken. At this time, the elastic force of the return spring 4118 will push the locking rod 4116 to move outward, causing the other end of the locking rod 4116 to disengage from the locking hole 416. Then, pull the locking block 415 out of the engaging groove of the mounting plate 4112 to complete the disassembly of the torque tool on the quick-release buckle carrying part.
