Description

Technical Field

[0001] This application relates to the field of hardware hand tools, and in particular to a water pump pliers with a quick-adjustable jaw. Background Technology

[0002] Pump pliers are a common hand tool, typically designed with an adjustable pivot for the sliding jaws. During use, the position of the sliding jaws is adjusted according to the size of the workpiece, thus changing the opening size of the jaws.

[0003] Most existing products require repeated adjustments to the position of the sliding jaws to change the opening size during use, in order to meet clamping needs. This adjustment process involves repeated tightening and loosening of the sliding jaws, and is cumbersome, inconvenient, and inefficient. Summary of the Invention

[0004] The purpose of this application is to provide a water pump clamp with a quick-adjustable jaw, so as to solve the defects of the prior art water pump clamps, which are cumbersome to operate and difficult to adjust when adjusting the size of the jaw opening.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0006] A water pump clamp with a quick-adjusting jaw, including

[0007] The first clamp body is provided with a sliding groove, and a first saw tooth is fixed on one side of the sliding groove along its length.

[0008] The second clamp body is provided, wherein the first clamp body passes through the through groove on the second clamp body and is rotatably mounted to the first clamp body, and the second clamp body is movable along the length direction of the groove;

[0009] An adjustment component is slidably installed in the through groove. The adjustment component intermittently contacts the first saw teeth to position the distance between the jaws of the first clamp and the second clamp.

[0010] In a further embodiment of this application, the first clamp body and the second clamp body are rotatably mounted via a pivot.

[0011] In a further embodiment, the adjustment assembly includes a movable component and a button connector. The movable component is movably mounted within the slide groove, and the rotating shaft passes through the movable component. A second sawtooth is fixed to the side of the movable component near the first sawtooth, and a second spring is fixed to the side of the movable component away from the first sawtooth. The button connector is fixedly connected to the top end of the rotating shaft and connected to a first spring in the second clamp. The rotating shaft moves to contact the inner wall of the movable component, so that the first sawtooth and the second sawtooth engage intermittently.

[0012] In a further embodiment, the inner wall of the moving part away from the second sawtooth is provided with a first inclined surface, and a second inclined surface is provided on the rotating shaft. The first inclined surface and the second inclined surface interact with each other to move the moving part.

[0013] In a further embodiment, the upper and lower outer walls of the through groove of the second clamp body are provided with countersunk holes, the first spring is connected to the upper countersunk hole, and a fastener is provided in the lower countersunk hole, and the rotating shaft is fixedly connected to the fastener.

[0014] In a further embodiment, the adjustment assembly also includes a limiting member located within the groove on the lower side of the moving member, and the rotating shaft movably passes through the limiting member to connect to the fastener.

[0015] In a further embodiment, the tooth angle of the first saw tooth is arranged at an acute angle to the mounting surface of the first saw tooth.

[0016] In a further embodiment of this application, the cross-section of the first clamp body and the handle of the second clamp body are T-shaped.

[0017] Compared with the prior art, the beneficial effects achieved by this application are as follows:

[0018] In this application, a first saw tooth is fixed on the first clamp body, and a movable adjustment component is provided on the second clamp body. When in use, the adjustment component is separated from the first saw tooth. At this time, the second clamp body moves along the slide groove to control the jaw distance between the two clamp bodies. When the adjustment component contacts the first saw tooth, the second clamp body is positioned. The adjustment is convenient and quick, and the stability is high, greatly increasing the adjustment efficiency.

[0019] The adjustment component is equipped with a second saw tooth, and the tooth angle of the first saw tooth is an acute angle with its mounting surface. Due to this structural design, the second saw tooth can move obliquely upward along the tooth angle of the first saw tooth until the first clamp body is in place. At this time, the push of the second spring causes the second saw tooth and the first saw tooth to mesh again, and the second clamp body can slide to adjust the gap of the jaws, further accelerating the adjustment speed of the jaws.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0026] Reference Appendix Figure 1 and 2 This embodiment discloses a water pump clamp with a quick-adjustable jaw, which includes a first clamp body 1, a second clamp body 6, and an adjustment component 4. The first clamp body 1 and the second clamp body 6 are hinged by a pivot, and one end of the first clamp body 1 extends with a first jaw 101, and one end of the second clamp body 6 extends with a second jaw 601. The first clamp body 1 is provided with a sliding groove 3, and a first serration 2 is fixed on one side of the sliding groove 3 along its length. The first clamp body 1 passes through a through groove 5 on the second clamp body 6 and is rotatably mounted with the first clamp body 1, and the second clamp body 6 can move along the length of the sliding groove 3; the adjustment component 4 is slidably mounted in the through groove 5.

[0027] During operation, the adjusting component 4 intermittently contacts the first saw tooth 2. When the two are in contact, the distance between the jaws of the first clamp body 1 and the second clamp body 6 is fixed. When the two are separated, the second clamp body 6 can slide to quickly adjust the size of the jaws of the water pump clamp.

[0028] Reference Appendix Figure 2 and 3The specific structure and installation method of the adjustment component 4 in this embodiment can be seen in the accompanying drawings. The adjustment component 4 includes a movable part 12, which has a through hole. The movable part 12 is movably installed in the slide groove 3 and is penetrated by a rotating shaft. A second sawtooth 13 is fixed to the side of the movable part 12 near the first sawtooth 2, and a second spring 9 is fixed to the side of the movable part 12 away from the first sawtooth 2. The second spring 9 abuts against the side wall of the slide groove 3 away from the second sawtooth 13. A button connector 8 is fixed to the top of the rotating shaft, and the button connector 8 is connected to the second clamp body 6. A first spring 14 is connected. Pressing the button connector 8 causes the rotating shaft to move and contact the inner wall of the moving part 12, so that the first saw tooth 2 and the second saw tooth 13 intermittently engage. It should be noted that in this embodiment, a limiting member 10 is also provided in the slide groove 3 on the lower side of the moving part 12. The width of the limiting member 10 matches the width of the slide groove 3. The rotating shaft moves through the limiting member 10 and connects to the fastener 11. If necessary, a strip groove can be opened on the side wall of the slide groove 3, and the limiting member 10 can be placed in the strip groove. The strip groove can stably limit the movement direction of the second saw tooth 13.

[0029] Considering the repeated pressing of the button connector 8, when installing the rotating shaft, countersunk holes 7 are opened on the upper and lower outer walls of the through groove 5 of the second clamp body 6. The first spring 14 is connected to the upper countersunk hole 7, and a fastener 11 is fixed in the lower countersunk hole 7. The rotating shaft is press-fitted and riveted to the fastener 11. When in use, the rotating shaft moves back and forth under the pressing of the button connector 8, and the fastener 11 has a limiting function.

[0030] Reference Appendix Figure 2 and 3 In this embodiment, the use of inclined surfaces is used to achieve intermittent engagement between the first saw tooth 2 and the second saw tooth 13. A first inclined surface 131 is provided on the inner wall of the moving part 12 away from the second saw tooth 13, and a second inclined surface 132 is provided on the rotating shaft. The first inclined surface 131 and the second inclined surface 132 interact with each other, causing the moving part 12 to move.

[0031] In some embodiments, the matching angle of the tooth angles of the first saw tooth 2 and the second saw tooth 13 is designed. In another embodiment, the tooth angle of the first saw tooth 2 and the mounting surface of the first saw tooth 2 are designed to be an acute angle, here designed to be 60°. The purpose of this design is to facilitate the upward movement of the second clamp body 6 and to ensure the stability of the water pump clamp during use. See attached figure. Figure 1When the jaws of the first clamp 1 and the second clamp 6 clamp the object (nut or regulating valve stem), the second clamp 6 moves clockwise. Analyzing the force direction of the first saw tooth 2 and the second saw tooth 13, the saw tooth angle design can meet the smooth operation of the two clamps. In addition, when the second clamp 6 moves obliquely upward, due to the tooth angle design, the second saw tooth 13 and the first saw tooth 2 can move relative to each other. During the process, the second spring 9 is compressed until the second saw tooth 13 stops moving. At this time, driven by the second spring 9, the second saw tooth 13 and the first saw tooth 2 are engaged and positioned. The jaw spacing of this water pump clamp is very convenient to adjust.

[0032] In another embodiment, the cross-section of the handles of the first clamp body 1 and the second clamp body 6 is T-shaped, which helps to increase the contact area with the rubber sleeve and increase the tightness of the fit between the rubber sleeve and the handle.

[0033] Specific usage:

[0034] When adjusting the jaws of the water pump clamp, the operator presses the button connector 8 with their finger. At this time, the rotating shaft moves down and achieves the squeezing contact of the first inclined surface 131 and the second inclined surface 132. Because the lateral position of the first inclined surface 131 is fixed, the second inclined surface 132 (second saw tooth 13) moves away from the first saw tooth 2. The operator can move the second clamp body 6 up and down. At this time, the distance between the first jaw 101 and the second jaw 601 changes. When the operator releases the button connector 8, the button connector 8 is reset by the first spring 14, and the second saw tooth 13 is reset by the second spring 9. At this time, the workpiece can be operated.

[0035] In addition, the second clamp body 6 can be moved directly upwards. The second clamp body 6 is eventually reset and fixed under the action of the second spring 9 (the specific process has been described in detail above, so it will not be repeated here). This application can quickly and efficiently adjust the jaw spacing of the water pump clamp to adapt to workpieces of different sizes. It is ingeniously designed, highly practical, and worthy of market promotion.
