Description

Technical Field

[0001] This utility model relates to the technical field of explosion-proof adjustable wrenches, and in particular to a locking structure for an explosion-proof adjustable wrench with quick adjustment of the opening. Background Technology

[0002] Explosion-proof adjustable wrenches are hand tools suitable for use in flammable and explosive hazardous locations such as oil, petrochemical, and natural gas industries. When subjected to mechanical friction or impact, the heat generated by the explosion-proof adjustable wrench is absorbed and conducted away within a short time. Because copper is relatively soft, it exhibits excellent yielding properties during friction and impact, making it difficult to generate tiny metal particles, resulting in virtually no visible sparks and thus avoiding the risk of igniting flammable and explosive gases.

[0003] Currently, when adjusting the opening size of an explosion-proof adjustable wrench, the adjustment screw is rotated, which drives the knurling to rotate and moves the movable jaws. However, when a larger adjustment is needed, the operator needs to rotate the adjustment screw many times to achieve the required opening size. This reduces the adjustment speed of the explosion-proof adjustable wrench and thus reduces its ease of use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a locking structure for an explosion-proof adjustable wrench with a quick-adjustable opening.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An explosion-proof adjustable wrench locking structure with quick-adjustment opening includes a wrench body. The surface of the wrench body is threadedly connected to a clamping rod through a threaded hole. One end of the clamping rod is equipped with three handles, and the other end of the clamping rod is equipped with a rubber pad. The rubber pad abuts against a groove. The groove is machined on the surface of a sliding rod. The outer wall of the sliding rod is fixedly connected to the movable jaw. The sliding rod is inserted into a through hole on the surface of the wrench body. The upper surface of the wrench body is slidably connected to the movable jaw through a sliding track.

[0007] Preferably, the end of the slide bar is machined with a disc.

[0008] Preferably, the clamping rod moves through the wrench body via a threaded hole.

[0009] Preferably, a fixed jaw is installed at the upper end of the wrench body.

[0010] Preferably, the included angle between adjacent handles of the three handles is 120°.

[0011] Preferably, the two sides of the wrench body that come into contact with the movable jaws are machined with graduations.

[0012] Preferably, both sides of the movable jaws are machined with scale pointers.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The wrench body, clamping rod, handle, rubber pad, retaining groove, sliding rod, and movable jaws are designed to adjust the opening of the explosion-proof adjustable wrench. When adjustment is needed, the operator holds the handle and rotates it. The handle rotates the clamping rod. Because the clamping rod has threads machined in the middle and is threaded to the wrench body, its rotation moves the rubber pad at the bottom away from the retaining groove. Once the clamping rod is no longer in contact with the retaining groove, the operator stops rotating the handle and then pulls the disc outwards. The disc moves the sliding rod. The fixed movable jaw moves along the upper part of the disc until the distance between the movable jaw and the fixed jaw reaches the appropriate position. Then, the disc stops moving and the handle is rotated in the opposite direction. The handle drives the rubber pad to press against the slot of the slide rod through the above transmission method, thus fixing the position of the slide rod. This allows the opening of the explosion-proof adjustable wrench to be adjusted to the required position in a short time when the opening needs to be adjusted quickly. This avoids the situation where the opening adjustment needs to be taken for a long time during use, and improves the ease of use of the locking structure of the explosion-proof adjustable wrench.

[0015] 2. By configuring the wrench body, scale, movable jaw, and scale pointer, when precise adjustment of the opening degree of the explosion-proof adjustable wrench is required, the operator moves the movable jaw in the manner described above. As the movable jaw moves, the operator observes the position of the scale pointer on the movable jaw to determine the opening degree between the fixed jaw and the movable jaw. This method allows for precise adjustment of the opening degree of the explosion-proof adjustable wrench, thereby improving its working efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 An explosion-proof adjustable wrench locking structure with quick-adjustment opening includes a wrench body 1. The surface of the wrench body 1 is threadedly connected to a clamping rod 7 through a threaded hole. The clamping rod 7 can move outward or inward while rotating inside the wrench body 1. Three handles 8 are installed at one end of the clamping rod 7, which facilitates the operator to rotate the clamping rod 7. A rubber pad 6 is installed at the other end of the clamping rod 7. The clamping rod 7 drives the rubber pad 6 to move, and the rubber pad 6 abuts against the groove 5, increasing the friction between the rubber pad 6 and the groove 5. The groove 5 is machined on the surface of a sliding rod 3. The clamping rod 7 fixes the position of the sliding rod 3. The outer wall of the sliding rod 3 is fixedly connected to a movable jaw 10. The sliding rod 3 drives the movable jaw 10 to move. The sliding rod 3 is inserted into a through hole on the surface of the wrench body 1 and slides inside the wrench body 1. The upper surface of the wrench body 1 is slidably connected to the movable jaw 10 through a slide rail, and the movable jaw 10 slides on the wrench body 1. When adjusting the opening of the explosion-proof adjustable wrench, the operator holds a handle 8 and rotates it. The handle 8 causes the clamping rod 7 to rotate. Because the clamping rod 7 has threads machined in the middle and is threadedly connected to the wrench body 1, when the clamping rod 7 rotates, it will cause the rubber pad 6 at the bottom to move away from the groove 5. When the clamping rod 7 is no longer in contact with the groove 5, the operator stops rotating the handle 8 and then pulls the disc 4 outward. The disc 4 causes the sliding rod 3 to move, and the sliding rod 3 causes the fixed movable jaw 10 above to move. After the distance between the movable jaw 10 and the fixed jaw 2 reaches the appropriate position, the moving disc 4 is stopped, and then the handle 8 is rotated in the opposite direction. The handle 8 drives the rubber pad 6 to press against the groove 5 of the slide rod 3 through the above transmission method, thus fixing the position of the slide rod 3. This allows the opening degree of the explosion-proof adjustable wrench to be adjusted to the required position in a short time when it is necessary to adjust the opening degree quickly, thereby avoiding the situation that the opening degree adjustment needs to take a long time during use and improving the ease of use of the locking structure of the explosion-proof adjustable wrench.

[0024] In this embodiment, a disc 4 is machined at the end of the slide bar 3, and the clamping rod 7 passes through the wrench body 1 through a threaded hole. A fixed jaw 2 is installed at the upper end of the wrench body 1. The adjacent included angles of the three handles 8 are all 120°, which makes it convenient for the operator to rotate the handles 8 under any circumstances. The two sides of the wrench body 1 that contact the movable jaw 10 are machined with scales 9, which make it convenient for the operator to make precise adjustments to the opening. The two sides of the movable jaw 10 are machined with scale pointers 11, which make it convenient for the operator to observe the movement distance of the movable jaw 10.

[0025] The working principle of this embodiment is as follows: When adjusting the opening of the explosion-proof adjustable wrench, the operator holds a handle 8 and rotates it. The handle 8 drives the clamping rod 7 to rotate. Since the clamping rod 7 has threads machined in the middle and is threadedly connected to the wrench body 1, when the clamping rod 7 rotates, it will drive the rubber pad 6 at the bottom away from the slot 5. When the clamping rod 7 is no longer in contact with the slot 5, the operator stops rotating the handle 8 and then pulls the disc 4 outward. The disc 4 drives the slide rod 3 to move, and the slide rod 3 drives the fixed movable jaw 10 above to move. After the distance between the movable jaw 10 and the fixed jaw 2 reaches a suitable position, the operator stops. Stop the moving disc 4, then rotate the handle 8 in the opposite direction. The handle 8 drives the rubber pad 6 to press against the slot 5 of the slide rod 3 through the above transmission method, fixing the position of the slide rod 3, thereby fixing the position of the movable jaw 10. When it is necessary to precisely adjust the opening degree of the explosion-proof adjustable wrench, the operator moves the movable jaw 10 in the above manner. When the movable jaw 10 moves, the operator observes the position of the scale pointer 11 on the scale 9 on the movable jaw 10 to know the opening degree between the fixed jaw 2 and the movable jaw 10, thereby precisely adjusting the opening degree of the explosion-proof adjustable wrench and making it easier for the operator to use.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
