Description

Technical Field

[0001] The utility model belongs to the technical field of water pump pliers, in particular to a pair of quick-adjust water pump pliers. Background Art

[0002] Water pump pliers generally refer to tools used to clamp flat or cylindrical metal parts. Water pump pliers are often used in the installation and maintenance of automobiles, internal combustion engines, indoor pipes, etc. The main feature of water pump pliers is that the opening width can be adjusted, usually to multiple positions, to meet the needs of clamping parts of different sizes. When clamping parts of different sizes and need to change the opening width of the water pump pliers, quick-adjust water pump pliers are usually used.

[0003] The quick-adjust water pump pliers currently on the market have the following problems when used:

[0004] 1. When using traditional quick-adjust water pump pliers, the requirements for the length of the pliers body are different due to different use environments. Workers usually need to carry multiple quick-adjust water pump pliers with different pliers body lengths, and then select the quick-adjust water pump pliers with the appropriate length of pliers body according to the needs of the actual use environment to perform operations, which leads to poor compatibility of the quick-adjust water pump pliers when in use, and is not conducive to use in deep spaces;

[0005] 2. When using traditional quick-adjust water pump pliers, it is usually necessary to clamp parts of different sizes. Therefore, it is necessary to use an adjustment component to adjust the opening width of the water pump pliers to match the opening width with the size of the parts that need to be clamped. Since the adjustment component part needs to be moved frequently, the movable structural part of the adjustment component will show different degrees of wear, and the traditional adjustment component structure is usually integrally cast on the pliers body, so it cannot be replaced separately after wear, and the water pump pliers can only be replaced as a whole, which increases the maintenance and use costs to a certain extent.

[0029] In order to better understand the purpose, structure and function of the utility model, the quick-adjust water pump pliers of the utility model are further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-6 As shown, a quick-adjust water pump pliers of the utility model comprises a first pliers body 1, a second pliers body 2, a first pliers head 3 and a second pliers head 4, the first pliers body 1 is provided with a first pliers head 3 on the top, the second pliers body 2 is provided with a second pliers head 4 on the top, the first pliers body 1 and the second pliers body 2 are both provided with a cavity inside, an extension handle 8 is provided inside the cavity, the first pliers body 1 is connected to the extension handle 8 by a rivet 7, the second pliers body 2 is connected to the extension handle 8 by a rivet 7, the extension handle 8 is located inside the cavity of the first pliers body 1 and the second pliers body 2, and the rivet 7 is used to cooperate with the extension handle 8 to take out the extension handle 8 from the cavity by rotating when needed, the first pliers body 1 and the second pliers body 2 are both fixedly connected with baffles 9 on the sides, and the baffles 9 fixedly connected on the sides of the first pliers body 1 and the second pliers body 2 can limit the extension handle 8 when the extension handle 8 is taken out from the cavity by the staff.

[0031] The side surfaces of the first pliers body 1 and the second pliers body 2 both have inner grooves 10, and the shape of the inner grooves 10 is semicircular. The semicircular inner grooves 10 on the side surfaces of the first pliers body 1 and the second pliers body 2 allow the staff to easily remove the extended handle 8 from the cavity by simply pinching the upper and lower surfaces of the extended handle 8 when they need to take out the extended handle 8.

[0032] A magnet block 19 is provided inside the cavity of the first pliers body 1 and the second pliers body 2, and the magnet block 19 is attached to the top of the extension handle 8. By setting the magnet block 19 inside the cavity, when the extension handle 8 is put back into the cavity after use, the extension handle 8 can be fixed inside the cavity by magnetic adsorption, so that the extension handle 8 will not be exposed from the cavity when it is not needed.

[0033] The surfaces of the first caliper body 1 and the second caliper body 2 are both provided with an inner concave surface 5, and the interior of the inner concave surface 5 is connected to a first anti-slip pad 6 by bonding. By bonding the first anti-slip pad 6 inside the inner concave surface 5, when the staff holds the water pump caliper body, the friction with the contact surface is increased and the anti-slip effect is improved.

[0034] The surface of the extension handle 8 is bonded with a second anti-slip pad 11 in a circumferential manner. The second anti-slip pad 11 is square in shape. By surrounding the second anti-slip pad 11 bonded to the surface of the extension handle 8, when the staff needs to use the extension handle 8, the friction between the extension handle 8 and the contact surface is increased, thereby improving the anti-slip effect of the extension handle 8 when holding it.

[0035] A square groove 15 is provided inside the first pliers head 3, an adjusting block 13 is provided inside the square groove 15, clamping blocks 16 are provided on both sides of the adjusting block 13, a clamping groove 17 is provided inside the first pliers head 3, the clamping block 16 is embedded inside the clamping groove 17, screw holes are provided inside the clamping block 16 and the clamping groove 17, bolts 18 are inserted into the screw holes, an adjusting cavity 14 is provided inside the adjusting block 13, a half-thread bolt 12 is inserted into the adjusting cavity 14, the first pliers head 3 is connected to the second pliers head 4 through the half-thread bolt 12, and the second pliers head 4 is connected to the second pliers head 4 through the half-thread bolt 12. The head 4 is located below the first pliers head 3. Through the square groove 15 provided inside the first pliers head 3 and the adjusting block 13 provided inside the square groove 15, together with the clamping blocks 16 provided on both sides of the adjusting block 13 and the clamping groove 17 provided inside the first pliers head 3, the adjusting block 13 can be connected to the first pliers head 3 by embedding. In this way, after the adjusting block 13 is worn out due to long-term use, it is only necessary to separate the adjusting block 13 from the first pliers head 3 to complete the operation of replacing the adjusting component. There is no need to replace the water pump pliers as a whole, thereby reducing the maintenance and use costs.

[0036] The working principle of the quick-adjust water pump pliers: When using the quick-adjust water pump pliers, the staff first needs to align the clamp blocks 16 provided on both sides of the adjustment block 13 with the clamp slots 17 opened inside the first clamp head 3, and then insert the clamp block 16 into the inside of the clamp slot 17, and then insert the bolt 18 into the screw holes opened in the clamp block 16 and the clamp slot 19, so that the connection between the adjustment block 13 and the first clamp head 3 can be completed, and then the half-thread bolt 12 can be inserted into the adjustment cavity 14, so that the connection between the first clamp head 3 and the second clamp head 4 can be completed. When the adjusting cavity 14 is worn out with the increase of the use time, the staff only needs to remove the bolt 18 and the half-thread bolt 12, and then take out the block 16 from the inside of the card slot 17 to complete the operation of replacing the adjusting component. There is no need to replace the water pump pliers as a whole, which reduces the maintenance and use costs. When the staff holds the pliers body during use, the first anti-skid pad 6 provided on the surface of the first pliers body 1 and the second pliers body 2 can be used to increase the friction of the contact surface and improve the anti-skid effect. When the staff needs to use the extended handle 8, with the help of the semicircular inner groove 10 provided on the sides of the first pliers body 1 and the second pliers body 2, only the upper and lower surfaces of the extended handle 8 can be pinched, and the extended handle 8 can be taken out from the cavity by rotating with the rivet 7, so that when the staff cope with different environments, there is no need to carry multiple fast-adjusting water pump pliers with different lengths of pliers, which improves the compatibility of the fast-adjusting water pump pliers when in use, and is conducive to use in a deep space. At the same time, with the help of the second anti-skid pad 11 surrounding and bonding on the surface of the extended handle 8, the staff can hold the water pump pliers. When the extension handle 8 is held, the friction between the extension handle 8 and the contact surface is increased, and the anti-slip effect of the extension handle 8 when held is improved. With the help of the baffle 9 fixedly connected to the sides of the first pliers body 1 and the second pliers body 2, the extension handle 8 can be limited when the extension handle 8 is taken out of the cavity for use by the staff. When the extension handle 8 is put back into the cavity after use, the extension handle 8 can be fixed in the cavity by magnetic adsorption with the help of a magnet block 19 arranged inside the cavity, so that the extension handle 8 will not be exposed from the cavity when it is not needed.
