Description

Technical Field

[0001] The present invention belongs to the technical field of adjustable wrenches, and specifically relates to a multi-functional adjustable wrench with an adjustable opening. Background Art

[0002] A wrench is a commonly used installation and disassembly tool, which is a manual tool that uses the lever principle to turn bolts, screws, nuts, and other threaded fasteners with openings or socket holes for holding bolts or nuts. Wrenches are usually made of structural steel of carbon or alloy materials.

[0003] For example, the invention with the publication number CN104227624A discloses a multi-functional adjustable wrench, which includes a handle and a head. The head includes a fixed jaw, a movable jaw, a chute, a receiving groove, and a worm. The fixed jaw is arranged at one end of the head. A row of teeth is provided at the bottom of the movable jaw, and the row of teeth is slidably arranged in the chute. The worm is arranged in the receiving groove and meshes with the row of teeth; a hammer head is provided on the side of the fixed jaw opposite to the engaging surface; teeth are provided on the engaging surface of the movable jaw; a hollow notch is provided on the handle. The structure of the present invention is light, flexible, convenient to use, improves work efficiency, has strong practicability, and is suitable for popularization and application.

[0004] Existing multi-functional adjustable wrenches (such as traditional adjustable wrenches, etc.) usually adopt a worm - worm gear adjustment mechanism. By rotating the adjustment knob, the position of the movable jaw is changed to clamp nuts or bolts of different sizes. However, traditional adjustable wrenches only have basic clamping and rotating functions and cannot effectively prevent the nut from slipping out of the opening during the application of force. When the wrench is used in a narrow space or a high-torque environment, due to the lack of a limiting structure, the nut is likely to slip out of the jaw due to uneven force or deviation of the operating angle, resulting in operation failure or even damage to the workpiece.

[0005] Therefore, a multi-functional adjustable wrench with an adjustable opening is proposed to solve the problems raised in the background art. Summary of the Invention

[0006] To solve the problems raised in the above background art, the present invention provides a multi-functional adjustable wrench with an adjustable opening.

[0007] To achieve the above object, the present invention provides the following technical solution: A multi-functional adjustable wrench with an adjustable opening, including a wrench body. A clamping block is slidably arranged on one side of the top opening of the wrench body. The distance between the clamping block and its symmetrical side is adjustable to adapt to nuts of different sizes. A clamping groove is provided on the clamping block;

[0008] An adjusting block, which is located on the wrench body and fixedly connected to the clamping block, is used to adjust and reset the position of the clamping block;

[0009] A stabilizing mechanism, which is installed on the clamping block and is used to limit the opening position of the wrench body to avoid the problem of falling off from the opening when applying force to the nut by using the wrench body and the clamping block.

[0010] Preferably, the stabilizing mechanism includes a mounting block, two steel wires fixed on the symmetric two sides of the mounting block, a rubber sleeve sleeved on the two steel wires, two adjusting components arranged on the side of the wrench body away from the clamping block, a connecting frame arranged between the two adjusting components, and a disassembly and assembly component arranged on the connecting frame.

[0011] Preferably, the mounting block is fixedly connected to the side of the clamping block close to the opening of the wrench body, and the mounting block is in an L shape.

[0012] Preferably, the rubber sleeve is made of rubber and has elasticity, and the rubber sleeve contacts the fixed nut.

[0013] Preferably, the adjusting component includes two symmetric adjusting rollers arranged on the symmetric side of the wrench body away from the clamping block, two fixing frames respectively rotationally connected to the two adjusting rollers, and two knobs fixedly arranged on the tops of the two adjusting rollers.

[0014] Preferably, two steel wires are respectively wound on the two adjusting rollers, and the ends of the steel wires away from the mounting block are respectively fixedly connected to the two adjusting rollers.

[0015] Preferably, both of the two fixing frames are in a U shape and are respectively clamped on both sides of the wrench body, the two knobs are respectively rotationally connected to the tops of the fixing frames, and the two knobs are used to drive the two adjusting rollers to rotate, so that the steel wires on both sides are automatically wound up.

[0016] Preferably, the tops of the two fixing frames are fixedly connected to the connecting frame, the connecting frame is in a trapezoidal shape, and the disassembly and assembly component is used for quickly disassembling and assembling the connecting frame and the wrench body.

[0017] Preferably, the disassembly and assembly component includes a clamping block fixedly installed at the bottom of the connecting frame, a placing groove opened on the clamping block, a fixing hole opened on the clamping groove and communicated with the placing groove, a spring fixedly arranged inside the placing groove, a plug rod fixedly installed on the side of the spring away from the placing groove, and a sliding groove opened on the clamping block and the connecting frame.

[0018] Preferably, the plug rod is slidably inserted into the fixing hole, an adjusting rod is fixedly arranged on the outer wall of the plug rod close to the spring, the adjusting rod slides along the sliding groove, a fixing rope is fixedly arranged on the top of the adjusting rod, a fixing rod is fixedly arranged on the top of the connecting frame, and the fixing rope is hung on the fixing rod.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] Through the cooperation of structures such as mounting blocks, steel wire ropes, rubber sleeves, and adjustment components, the present invention facilitates the improvement of the stability when using the wrench body to turn nuts. By adjusting the opening size of the clamping block and the wrench body to fit the nut, and after clamping, a stabilizing mechanism is used to prevent the nut from slipping off: pulling the steel wire rope to fix it on the other side of the wrench to form a closed limit, the rubber sleeve enhances stability, and the adjustment component tightens the steel wire rope to ensure uniform force and prevent loosening, thus safely and reliably completing the nut tightening operation, solving the problems of the existing adjustable wrench having a single function, lacking a limiting component, being unable to effectively prevent the nut from slipping off from the opening during the force application process, and easily causing the nut to slip out of the jaws due to uneven force or deviation of the operation angle.

[0021] Through the cooperation of structures such as adjusting rollers, fixing frames, and knobs, the present invention facilitates the automatic winding of the steel wire rope. This adjustment component adopts a modular design concept and can precisely control the length of the steel wire rope according to the operation requirements. When dealing with small nuts, the operator only needs to first fix the disassembly and assembly component, and then rotate the knob with an ergonomic design clockwise, and the adjusting roller can be driven to rotate smoothly through the transmission mechanism, so that the steel wire rope is wound and tightened evenly and orderly to form a reliable limiting constraint; when encountering large nuts, only rotate the knob in the reverse direction, and the adjusting roller will rotate in reverse synchronously, intelligently releasing the length of the steel wire rope, so that the clamping opening expands accordingly, perfectly adapting to different specifications of nut sizes. This innovative structure with two-way adjustment not only ensures the stable clamping between the tool and the nut, but also greatly improves the operation efficiency. The entire adjustment process is smooth and natural, without the need to rely on additional tools, and precise length control can be achieved through simple knob operations. At the same time, combined with the anti-slip texture design on the surface of the knob, a stable operation feel can be ensured even in an oily environment. This design fully considers various requirements in the actual working conditions, not only ensures the reliability of the tightening operation, but also improves the convenience of use, reflecting the humanized engineering design concept.

[0022] Through the cooperation of structures such as clamping blocks, springs, and fixed rods, the present invention facilitates the quick disassembly and assembly of the connecting frame. The disassembly and assembly component can achieve the quick installation of the connecting frame and the wrench body: push the adjusting rod to make the fixing rope hang on the fixed rod, insert the connecting frame into the card slot and then release the fixing rope, and the spring rebounds to drive the insertion rod to lock the fixing hole, thereby quickly fixing the steel wire rope, and cooperating with the rubber sleeve to achieve stable limitation of the nut.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figures 1 to 7 shown, the present invention provides a multi-functional adjustable open-end wrench, including a wrench body 1. A clamping block 11 is slidably arranged on one side of the top opening of the wrench body 1. The distance between the clamping block 11 and its symmetrical side is adjustable to adapt to nuts of different sizes. A card slot 111 is provided on the clamping block 11;

[0033] An adjusting block 2, which is located on the wrench body 1 and fixedly connected to the clamping block 11, is used to adjust and reset the position of the clamping block 11;

[0034] A stabilizing mechanism 3, which is installed on the clamping block 11 and is used to limit the opening position of the wrench body 1 to avoid the problem of falling off from the opening when applying force to the nut by using the wrench body 1 and the clamping block 11;

[0035] The stabilizing mechanism 3 includes an installation block 31, two wire ropes 32 fixedly arranged on the two symmetric sides of the installation block 31, a rubber sleeve 33 sleeved on the two wire ropes 32, two adjusting components 34 arranged on the side of the wrench body 1 away from the clamping block 11, a connecting frame 35 arranged between the two adjusting components 34, and a disassembly and assembly component 36 arranged on the connecting frame 35. The installation block 31 is fixedly connected to the side of the clamping block 11 close to the opening of the wrench body 1, and the installation block 31 is in an L shape. The rubber sleeve 33 is made of rubber and has elasticity, and the rubber sleeve 33 contacts the fixed nut.

[0036] With the above scheme: Carry the wrench body 1 to the place where it is needed by hand. According to the size of the nut to be screwed, manually move the clamping block 11 and cooperate with the adjusting block 2 to adjust the opening size between the wrench body 1 and the clamping block 11. After the adjustment is completed, clamp the nut at the opening. At this time, in order to avoid the problem that directly screwing the nut easily causes the nut to slip off from the opening during the force application process, and it is easy for the nut to slip out of the jaws due to uneven force or deviation of the operation angle, the anti-drop of the nut can be realized by using the stabilizing mechanism 3;

[0037] The stabilizing mechanism 3 realizes more stable force on the nut. When the nut is clamped at the opening position, the other end of the wire rope 32 can be manually pulled to fix it on the wrench body 1 on the side away from the clamping block 11 by using the disassembly and assembly component 36. At this time, the wire rope 32 closes and limits the opening. The rubber sleeve 33 realizes more stable limitation to avoid the deformation of the wire rope 32 when the nut is stressed. Finally, according to the adjustment degree of the opening between the clamping block 11 and the wrench body 1, the length of the wire rope 32 is appropriately adjusted by using the adjusting component 34 to make it in a taut state, avoiding the problem that the wire rope 32 is randomly arranged and affects the limitation.

[0038] As Figure 4 shown, the adjusting component 34 includes two symmetric adjusting rollers 341 arranged on the two symmetric sides of the wrench body 1 away from the clamping block 11, two fixing frames 342 respectively rotatably connected to the two adjusting rollers 341, and two knobs 343 fixedly arranged on the tops of the two adjusting rollers 341;

[0039] Two wire ropes 32 are respectively wound on the two adjusting rollers 341. One end of the wire rope 32 away from the installation block 31 is respectively fixedly connected to the two adjusting rollers 341. The two fixing frames 342 are both in a U shape and are respectively clamped on both sides of the wrench body 1. The two knobs 343 are respectively rotatably connected to the tops of the fixing frames 342. The two knobs 343 are used to drive the two adjusting rollers 341 to rotate, so that the wire ropes 32 on both sides are automatically wound up.

[0040] Adopt the above solution: Moderately adjust the length of the steel wire rope 32 by adjusting the component 34. When the nut is small, move the clamping block 11 closer to the top opening of the wrench body 1. First, use the disassembly and assembly component 36 to fix the connecting frame 35 on the wrench body 1, and then fix the two fixing frames 342 on both sides. After the fixing is completed, manually rotate the knob 343 to drive the adjusting roller 341 to rotate synchronously, thereby realizing the winding of the steel wire rope 32 to make it taut, which is more convenient for limiting. When the nut is large, reverse the rotation of the knob 343 to drive the adjusting roller 341 to reverse, loosen it, and drive the steel wire rope 32 to loosen, so as to adapt to the situation where the opening between the clamping block 11 and the wrench body 1 is enlarged.

[0041] As Figures 6 to 7 shown, the tops of the two fixing frames 342 are fixedly connected to the connecting frame 35. The connecting frame 35 is in the shape of a trapezoidal frame. The disassembly and assembly component 36 is used for quickly disassembling and assembling the connecting frame 35 and the wrench body 1;

[0042] The disassembly and assembly component 36 includes a clamping block 361 fixedly installed at the bottom of the connecting frame 35, a placement groove 362 opened on the clamping block 361, a fixing hole opened on the clamping groove 111 and communicating with the placement groove 362, a spring 363 fixedly arranged inside the placement groove 362, a plug rod 364 fixedly installed on the side of the spring 363 away from the placement groove 362, and a sliding groove 365 opened on the clamping block 361 and the connecting frame 35. The plug rod 364 is slidably inserted into the fixing hole. A regulating rod 3641 is fixedly arranged on the outer wall of the plug rod 364 close to the spring 363. The regulating rod 3641 slides along the sliding groove 365. A fixing rope 3642 is fixedly arranged at the top of the regulating rod 3641. A fixing rod 366 is fixedly arranged at the top of the connecting frame 35. The fixing rope 3642 is hung on the fixing rod 366.

[0043] Adopt the above solution: Realize the quick disassembly and assembly of the connecting frame 35 and the wrench body 1 through the disassembly and assembly component 36. Specifically, manually move the regulating rod 3641 along the sliding groove 365 towards the side close to the fixing rod 366, so that the fixing rope 3642 is hung on the fixing rod 366. At this time, insert the entire connecting frame 35 and the clamping block 361 into the clamping groove 111. At this time, the spring 363 is in a compressed state. After the insertion is completed, remove the fixing rope 3642 from the fixing rod 366. At this time, the spring 363 loses its restraint and resets, driving the internal plug rod 364 to slide and be inserted into the fixing hole under the extrusion of the spring 363, thereby realizing the quick fixation of the connecting frame 35 and the wrench body 1, facilitating the fixation of the entire steel wire rope 32 on the wrench body 1, and realizing the limit of the nut through the rubber sleeve 33.

[0044] Working principle and usage process of the present invention: When using this device for nut tightening operation, first, the three core components, namely the wrench body 1, the clamping block 11, and the adjusting block 2, need to cooperate with each other. Through the carefully designed opening structure, the nut to be operated is firmly clamped at the predetermined position. After the initial clamping is completed, the operator needs to manually pull the steel wire rope 32, and the end close to the fixed frame 342 is precisely inserted into the internal cavity of the clamping block 11 along the guiding path of the connecting frame 35 arranged at the top of the device. At this time, the elastic locking mechanism composed of the spring 363 and the insertion rod 364 built in the device starts to function. The compression and resilience of the spring 363 drive the insertion rod 364 to achieve rapid positioning, thereby ensuring a firm fixing effect of the clamping block 361 and driving the fixed frames 342 on both sides into a stable working state. After the above preparatory work is completed, the operator only needs to manually rotate the ergonomically designed knob 343, and the adjusting roller 341 can be driven to rotate synchronously through the precise transmission mechanism, realizing the automatic winding function of the steel wire rope 32. During this process, the operator can fine-tune the tightness of the steel wire rope 32 by precisely controlling the rotation angle of the knob 343 according to the actual working conditions, so as to obtain the best restraint effect. It is worth mentioning that the specially configured high friction coefficient rubber sleeve 33 and the steel wire rope 32 of the device form a double protection system, which can achieve 360-degree all-round limit protection for the nut to be operated, effectively preventing the nut from accidentally loosening or displacing during the force application process, and greatly improving the safety and reliability of the operation. The entire operation process is scientifically and reasonably designed, and the components cooperate smoothly, which not only ensures the convenience of the operation, but also ensures the accuracy and stability of the tightening operation.
