Description

A type of water pump clamp with elastic self-locking buckle Technical Field

[0001] This utility model relates to the field of water pump clamps, and more specifically, to a water pump clamp with an elastic self-locking buckle. Background Technology

[0002] Pump wrenches function similarly to pipe wrenches, but are lighter, smaller, and easier to use. They are generally more suitable for non-professional emergency use or simple water pipe installation in the home. Of course, their clamping force is not as strong as that of pipe wrenches. They are used to clamp flat or cylindrical metal parts. Their feature is that the opening width of the jaws has multiple adjustable positions (three to four positions) to adapt to the needs of clamping parts of different sizes.

[0003] A search revealed that Chinese Patent Publication No. CN210879285U discloses a "water pump pliers," comprising two sets of pliers, each set having a jaw at its top and a handle at its bottom. One set of pliers has an internal sliding groove with a first serration on one side. A rotatable gear extending into the sliding groove of the other set of pliers is rotatably connected to the internal part of the pliers. This invention, by providing a sliding groove in the pliers with a precise first serration on one side of the groove, and a second serration matching the first serration on one side of the rotatable gear, and a recessed hole on the opposite side of the rotatable gear symmetrical to the second serration, contains a spring connected to a steel ball. When the spring is compressed, the rotatable gear slides. When it slides to a suitable opening, the second serration on one side of the rotatable gear engages with the first serration, allowing adjustment of the opening without pressing. However, it still has the following drawbacks:

[0004] (1) The existing water pump clamps have elastic buckles that directly push the clamping plate into the slot. The spacing is adjusted and fixed by clamping the plate into the slot. However, there are gaps between multiple slots, which creates dead angles in the clamping spacing and makes it impossible to fully cover the clamping area, thus affecting the integrity of the water pump clamp spacing adjustment.

[0005] (2) The existing buckle structure only uses the spring to insert and fix the buckle plate. During use, the vibration will affect the stability of the spring, thus affecting the fixing stability of the buckle.

[0006] Therefore, we have made improvements to this by proposing a water pump clamp with an elastic self-locking buckle. Summary of the Invention

[0007] The purpose of this utility model is to address the problems of existing water pump clamps where the elastic buckle directly pushes the clamping plate into the slot to achieve spacing adjustment and fixation. However, gaps exist between multiple slots, resulting in dead angles in the clamping spacing and failing to fully cover the clamping area. Furthermore, existing buckle structures rely solely on the spring's thrust to fix the clamping plate, which can cause vibrations during use that affect the spring's stability.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A water pump clamp with a flexible self-locking latch is provided to improve the above-mentioned problems.

[0010] The present invention is as follows:

[0011] It includes a first clamp bar, a first clamp is installed at the left end of the first clamp bar, an adjustment component is provided at the center of the first clamp bar, and a locking component is provided on the outer front side of the center of the first clamp bar.

[0012] The adjustable distance assembly includes an adjusting groove inside the middle section of the first clamp rod, a sliding groove on the side wall of the adjusting groove, a screw installed inside the sliding groove, a sleeve plate fitted on the outer wall of the screw, and a shaft column installed on the outer wall of the sleeve plate.

[0013] The locking assembly includes an outer plate mounted on the outer surface of the first clamp bar, and a through groove is provided inside the outer plate, in which a locking plate is movably installed.

[0014] As a preferred technical solution of this utility model, the side wall of the slide groove is provided with a side groove, and a side plate that cooperates with the side groove is installed on the side of the sleeve plate away from the shaft column.

[0015] As a preferred technical solution of this utility model, an inner groove is provided on the side of the slide away from the first clamp. A first bevel gear is provided on the inner wall of the inner groove near the slide. A second bevel gear is provided on the inner wall of the inner groove perpendicular to the screw, which cooperates with the first bevel gear. A knob is connected to the outer end of the second bevel gear.

[0016] As a preferred technical solution of this utility model, a limiting groove is provided on the side wall of the through groove, and a limiting plate that cooperates with the limiting groove is installed on the side wall of the locking plate.

[0017] As a preferred technical solution of this utility model, a telescopic rod is installed on the side wall of the limiting plate, and a spring is fitted on the outer wall of the telescopic rod.

[0018] As a preferred technical solution of this utility model, the rotation input end of the screw and the rotation output end of the first bevel gear are connected in a cooperative manner.

[0019] As a preferred technical solution of this utility model, a second clamping bar is rotatably mounted on the lower end of the shaft column, and a second clamping bar that cooperates with the first clamping bar is mounted on the side of the second clamping bar near the first clamping bar.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the solution of this utility model:

[0022] 1. By means of the screw, sleeve, side plate, first bevel gear, second bevel gear and knob, when it is necessary to adjust the clamping distance between the first clamp and the second clamp, the knob is turned to drive the second bevel gear connected to it to rotate, which in turn drives the first bevel gear to rotate, which in turn drives the screw connected to it to rotate. The sleeve is driven to slide in the slide groove through the threaded engagement on the outer wall. With the side plate embedded in the side groove, the shaft is driven to move stably in the adjustment groove, which can drive the second clamp to move vertically relative to the first clamp, thus completing the full range adjustment of the distance between the first clamp and the second clamp.

[0023] 2. Through the locking plate, limiting plate, telescopic rod, and spring, before turning the knob for adjustment, pulling the locking plate causes it to slide away from the knob. The locking plate slides in the through groove, causing the limiting plate to slide in the limiting groove. This compresses the telescopic rod and spring, causing them to contract and generate potential energy. After turning the knob for adjustment, releasing the tension on the locking plate causes the telescopic rod and spring to push the limiting plate, causing the locking plate to slide in the through groove towards the knob. The locking plate's surface is secured by a groove that engages with the knob's surface, providing a stable lock and improving the stability of the water pump clamp spacing adjustment.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0032] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] As shown in Figures 1-5, this embodiment proposes a water pump clamp elastic self-locking buckle, including a first clamp bar 1, a first clamp 2 installed on the left end of the first clamp bar 1, an adjustment component provided at the center of the first clamp bar 1, and a locking component provided on the outer side of the front side of the center of the first clamp bar 1.

[0036] The adjustable distance assembly includes an adjusting groove 301 inside the middle section of the first clamp rod 1, a sliding groove 302 on the side wall of the adjusting groove 301, a screw 303 installed inside the sliding groove 302, a sleeve plate 304 fitted on the outer wall of the screw 303, and a shaft column 311 installed on the outer wall of the sleeve plate 304.

[0037] The locking assembly includes an outer plate 401 mounted on the outer surface of the first clamp 1, and a through groove 402 is provided inside the outer plate 401. A locking plate 403 is movably installed inside the through groove 402.

[0038] As shown in Figure 3, the side wall of the slide groove 302 is provided with a side groove 305. The side plate 306 that cooperates with the side groove 305 is installed on the side of the sleeve plate 304 away from the shaft column 311. Under the limitation of the side plate 306 being embedded in the side groove 305, the shaft column 311 is driven to move stably in the adjustment groove 301, which can drive the second clamp rod 5 to move vertically relative to the first clamp rod 1.

[0039] As shown in Figure 3, an inner groove 307 is provided on the outer side of the slide groove 302 away from the first clamp 2. A first bevel gear 308 is provided on the inner wall of the inner groove 307 near the slide groove 302. A second bevel gear 309 is provided on the inner wall of the inner groove 307 perpendicular to the screw 303, which cooperates with the first bevel gear 308. A knob 310 is connected to the outer end of the second bevel gear 309. Twisting the knob 310 drives the second bevel gear 309 connected to it to rotate, which in turn drives the first bevel gear 308 to rotate, which in turn drives the screw 303 connected to it to rotate. The screw plate 304 is driven to slide in the slide groove 302 through the thread engagement provided on the outer wall.

[0040] As shown in Figure 4, a limiting groove 404 is provided on the side wall of the through groove 402, and a limiting plate 405 that cooperates with the limiting groove 404 is installed on the side wall of the locking plate 403. The limiting plate 405 is driven to slide in the limiting groove 404, which compresses the telescopic rod 406 and the spring 407, causing them to contract and generate potential energy. After the knob 310 is turned to adjust, the tension on the locking plate 403 is released, and the telescopic rod 406 and the spring 407 push the limiting plate 405, causing the locking plate 403 to slide in the direction of the knob 310 in the through groove 402.

[0041] As shown in Figure 4, a telescopic rod 406 is installed on the side wall of the limiting plate 405. A spring 407 is fitted on the outer wall of the telescopic rod 406. The telescopic rod 406 and the spring 407 compress each other to generate potential energy. When the knob 310 is turned for adjustment, the tension on the locking plate 403 is released. The telescopic rod 406 and the spring 407 push the limiting plate 405, causing the locking plate 403 to slide in the through groove 402 toward the knob 310. The locking plate 403 is locked in place by the grooves on the surface of the knob 310, thus stably locking the knob 310.

[0042] As shown in Figure 3, the rotation input end of the screw 303 is connected to the rotation output end of the first bevel gear 308. When the first bevel gear 308 rotates, it drives the screw 303 connected to it to rotate. Through the thread engagement provided on the outer wall, the sleeve 304 is driven to slide in the slide groove 302.

[0043] As shown in Figure 1, a second clamping rod 5 is rotatably mounted on the lower end of the shaft column 311. A second clamping clamp 6 that cooperates with the first clamping clamp 2 is installed on the side of the second clamping rod 5 near the first clamping clamp 2. The first clamping clamp 2 and the second clamping clamp 6 are adjusted to stably clamp water pump pipes of different sizes.

[0044] Specifically, when using this water pump clamp, if it is necessary to adjust the clamping distance between the first clamp 2 and the second clamp 6, turning the knob 310 rotates the second bevel gear 309 connected to it, which in turn rotates the first bevel gear 308, causing the screw 303 connected to it to rotate. Through the threaded engagement on the outer wall, the sleeve 304 slides in the slide groove 302. With the side plate 306 embedded in the side groove 305, the shaft 311 moves stably in the adjustment groove 301, thereby causing the second clamp 5 to move vertically relative to the first clamp 1, completing the full range adjustment of the distance between the first clamp 2 and the second clamp 6. When turning the knob 310... Before adjustment, pull the locking plate 403 to slide it away from the knob 310. The locking plate 403 slides in the through groove 402, causing the limiting plate 405 to slide in the limiting groove 404. This compresses the telescopic rod 406 and the spring 407, causing them to contract and generate potential energy. After adjusting the knob 310, release the pulling force on the locking plate 403. The telescopic rod 406 and the spring 407 push the limiting plate 405, causing the locking plate 403 to slide in the through groove 402 towards the knob 310. The locking plate 403 is locked in place by the grooves on the surface of the knob 310, thus stably locking the knob 310 and improving the stability of the water pump clamp spacing adjustment.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
