Description

Technical field:

[0001] The invention relates to the technical field of manual hardware tools, in particular to a quick adjustment method for water pump pliers. Background technology:

[0002] Conventional water pump pliers, such as those described in patent application CN218747156U, entitled "Anti-Pinch Water Pump Pliers," primarily comprise a fixed pliers body and a sliding pliers body, which are slidably connected by rivets. The fixed pliers body is provided with a long slot and a plurality of arcuate slots, and the sliding pliers body is provided with bosses that mate with the arcuate slots. To adjust the opening, the sliding pliers body must be opened to a wide angle, allowing the bosses of the sliding pliers body to disengage from the arcuate slots of the fixed pliers body. This allows the sliding pliers body to move back and forth within the long slots, completing the gear shift. After the gear shift, the sliding pliers body is then rotated in the opposite direction to insert the bosses into the corresponding arcuate slots. This operating method requires the sliding pliers body to be opened to a wide angle, making it difficult for the operator to determine the required opening relative to the object being clamped. Consequently, the opening is often too large or too small after a gear shift, making it incompatible with the object being clamped. This necessitates reopening the sliding pliers body and moving it again, requiring repeated adjustments to adjust the opening to the object being clamped. This results in cumbersome operation, slow clamping speed, and low efficiency. Currently, no effective solution to this problem exists.

[0003] In summary, how to quickly adjust the opening of water pump pliers to match objects has become a technical problem that urgently needs to be solved in the industry. Summary of the invention:

[0004] In order to make up for the deficiencies of the prior art, the present invention provides a quick adjustment method for water pump pliers, which solves the problem that water pump pliers in the past need to be adjusted repeatedly to match the opening amount with the object to be clamped, resulting in troublesome operation.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A quick adjustment method for water pump pliers comprises a fixed pliers body and a sliding pliers body, the fixed pliers body and the sliding pliers body are slidably connected by a turn pin, the fixed pliers body is provided with a long groove and a plurality of arc grooves, a slider is movably installed on the sliding pliers body at a position corresponding to the arc groove, a boss is provided on the inner side of the slider, the side wall of the arc groove has an inclined angle, and the boss matches the arc shape and the inclined angle of the side wall of the arc groove; when clamping an object, the sliding pliers body is first rotated open to disengage the boss from the arc groove, the sliding pliers body is moved backward along the long groove to an appropriate position, and then the sliding pliers body is closed to allow the boss to enter the arc groove, and then the jaws of the sliding pliers body are adjusted to be parallel to the jaws of the fixed pliers body, and the sliding pliers body is pushed forward. During the pushing, the boss pushes the slider upward, so that the sliding pliers body is gradually pushed forward and moved into the appropriate arc groove to clamp the object.

[0007] A sliding groove is provided on the sliding pliers body at a position corresponding to the arc groove, and a sliding block is movably installed in the sliding groove.

[0008] A limiting portion is provided between the slide groove and the slide block to prevent the slide block from falling.

[0009] The limiting portion includes a sinking groove arranged in the sliding groove, and the sliding block is provided with a step matched with the sinking groove.

[0010] An elastic pressing component is provided on the outer side of the sliding block.

[0011] The elastic pressing component includes a spring sheet, the fixed end of the spring sheet is pressed and fixed by a nut on the rotating pin, and the free end of the spring sheet is pressed on the sliding block.

[0012] The sliding caliper body is provided with a clamping groove which matches the shape of the spring sheet.

[0013] One end of the slot is a rotation pin hole, and the other end is a slide slot.

[0014] The present invention adopts the above solution and has the following beneficial effects:

[0015] The sliding jaw body is provided with a slide groove, a slider is movably installed in the slide groove, a boss that matches the arc groove is provided on the inner side of the slider, and an elastic pressing component is provided on the outer side of the slider. When clamping an object, it is only necessary to rotate the sliding jaw body open at the beginning to disengage the boss from the arc groove, and then move the sliding jaw body backward to an appropriate position, and then close the sliding jaw body to allow the boss to enter the arc groove, adjust the jaws of the sliding jaw body to be basically parallel with the jaws of the fixed jaw body, and then push the sliding jaw body forward. Since the boss and the arc groove have an inclination angle, the boss can push the slider upward when pushing, and the slider can be reset under the action of the spring sheet, so that the sliding jaw body can gradually move forward to the appropriate arc groove to clamp the object. When adjusting the opening amount, the sliding jaw body can directly move forward horizontally without repeated rotation adjustment. The parallel jaws make it easy for the operator to judge the required opening amount, which is convenient to operate and has a faster clamping speed. Description of the drawings:

[0022] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0023] like Figure 1-5 As shown, a method for quickly adjusting water pump pliers includes a fixed pliers body 1 and a sliding pliers body 2, the fixed pliers body 1 and the sliding pliers body 2 are slidably connected by a turn pin 3, a long slot 4 and a plurality of arc slots 5 are provided on the fixed pliers body 1, a slider 7 is movably installed at a position corresponding to the arc slot 5 on the sliding pliers body 2, a boss 8 is provided on the inner side of the slider 7, the side wall of the arc slot 5 has an inclined angle, the boss 8 matches the arc shape and the side wall inclination angle of the arc slot 5, and the specific design can be based on an upper side angle of 40 degrees and a lower side angle of 8 degrees. The slider 6 can be Push upward along the 40-degree surface, and the 8-degree surface can ensure that it cannot move downward. When clamping an object, first rotate the sliding pliers body 2 to open it so that the boss 8 disengages from the arc groove 5, and move the sliding pliers body 2 backward along the long groove 4 to an appropriate position, and then close the sliding pliers body 2 to allow the boss 8 to enter the arc groove 5, and then adjust the jaws of the sliding pliers body 2 to be parallel to the jaws of the fixed pliers body 1, and push the sliding pliers body 2 forward. When pushing, the boss 8 pushes the slider 5 upward, so that the sliding pliers body 2 is gradually pushed forward to the appropriate arc groove 5 to clamp the object.

[0024] A sliding groove 6 is provided on the sliding caliper body 2 at a position corresponding to the arc groove 5 , and a sliding block 7 is movably installed in the sliding groove 6 .

[0025] A limiting portion is provided between the slide groove 6 and the slider 7 to prevent the slider 7 from falling. The limiting portion includes a sink groove provided in the slide groove 6, and a step 9 is provided on the slider 7 to cooperate with the sink groove. When the sliding clamp body 2 is rotated open to make the boss 8 disengage from the arc groove 5, the step 9 cooperates with the sink groove to support the slider 7 and prevent the slider 7 from falling downward.

[0026] An elastic pressing component is provided on the outside of the slider 7, and the elastic pressing component includes a spring sheet 10. The fixed end of the spring sheet 10 is pressed and fixed by a nut 11 on the turn pin 3, and the free end of the spring sheet 10 is pressed on the slider 7. In a normal state, the spring sheet 10 can play a pressing and limiting role on the slider 7. When the sliding caliper body 2 is pushed upward in the arc groove 5, the slider 7 can push the spring sheet 10 upward to avoid interference.

[0027] The sliding caliper body 2 is provided with a clamping groove 12 that matches the shape of the spring piece 10. The clamping groove 12 can limit the position of the spring piece 10 to prevent the spring piece 10 from rotating.

[0028] One end of the slot 12 is a turn pin hole 13, and the other end is a slide slot 6. During installation, the turn pin 3 passes through the long slot 4 and the turn pin hole 13 to connect the fixed caliper body 1 and the sliding caliper body 2, and then the spring sheet 10 is installed. Finally, it is tightened by the nut 11. There is a certain amount of movable margin between the fixed caliper body 1 and the sliding caliper body 2, which can be rotated and moved.

[0029] Working principle:

[0030] When adjusting the opening amount of the clamped object, first rotate the sliding pliers body 2 to open it so that the boss 8 disengages the arc groove 5, then move the sliding pliers body 2 backward along the long groove 4 to the appropriate position, and then close the sliding pliers body 2 so that the boss 8 enters the arc groove 5, adjust the jaws of the sliding pliers body 2 to be basically parallel with the jaws of the fixed pliers body 1, and then push the sliding pliers body 2 forward. Since the boss 8 and the arc groove 5 have an inclination angle, the boss 8 can push the slider 7 upward when pushing, and will not interfere with the translation. The slider 7 can then be reset under the action of the spring sheet 10, so that the sliding pliers body 2 can be gradually moved forward to the appropriate arc groove 5. When adjusting the opening amount to clamp the object, the sliding pliers body 2 can be directly pushed forward in translation without repeated rotation and adjustment. The parallel jaws make it easy for the operator to judge the required opening amount, which is convenient to operate and has a faster clamping speed.

[0031] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention.
