Description

Technical Field

[0001] The utility model belongs to the technical field of wrenches, and in particular relates to an adjustable plum screw wrench. Background Art

[0002] In the preparation process of fine powder particle size material experiment and drum strength test in steel mills, vibrating screen machine and coke drum machine are needed. The plum screws on the drum cover of vibrating screen machine and coke drum machine are hand screws, and there are plum-shaped hand screws on them. During operation, cover the sieve cover with the particle size sample weighed with -200 mesh standard sieve as the container. Put it into the groove of the vibrating screen machine and loosen the plum screw to put down the pressure cover, and tighten the plum screw by hand. Because the wrist strength is small. The plum screw cannot be tightened thoroughly. When multiple -200 mesh standard sieves are tested at the same time, the -200 mesh standard sieve tilts out of the vibrating screen during the vibration of the vibrating screen machine, and the sample needs to be re-grinded to weigh the particle size sample. Excessive force on the wrist can easily damage the wrist. The drum cover of the coke drum machine also needs to tighten the plum screw. If it is not tightened, the drum cover will loosen. The drum cover rotates with the chute, causing the sample to spin out of the drum, resulting in the failure of the experiment. Re-sampling is required, which increases the labor intensity and poses equipment safety hazards. Summary of the invention

[0003] The utility model aims to provide an adjustable plum-shaped screw wrench to solve the problems existing in the prior art.

[0004] The utility model solves the technical problem by adopting the following technical scheme: an adjustable plum screw wrench comprises a wrench plate, a plurality of slide grooves are arranged on the wrench plate, a slide block is slidably connected to the slide groove, an adjusting bolt pair penetrating the slide groove and the slide block is penetrated by the slide block, a pulling rod is welded to the bottom end of the slide block, a clamping block is welded to the center above the wrench plate, a clamping sleeve is sleeved on the clamping block, and a wrench handle is welded to the top end of the clamping sleeve.

[0005] Furthermore, the slide groove is in the shape of an elongated strip, there are four slide grooves, the longitudinal center line of the slide groove is located on the diameter line of the wrench disk, and the four slide grooves are distributed in an array with the central axis of the wrench disk as the axis.

[0006] Furthermore, the width of the slider is greater than the width of the slide slot, the slider is located above the slide slot, and the trigger rod is welded to the bottom of the slider and passes through the slide slot.

[0007] Furthermore, the card block is square or hexagonal, and a card slot is provided at the bottom of the card sleeve. The shape of the card slot matches the outer contour of the card block, and the card sleeve is sleeved on the card block through the card slot.

[0008] The utility model has the following beneficial effects:

[0009] 1. The utility model can screw the plum screw without directly screwing it by hand, and can be adjusted according to the size of the plum screw, while reducing labor intensity, ensuring the tightening effect, and can adapt to plum screws of different models, with good safety.

[0010] 2. The position of the turning rod can be adjusted through the slide groove, slider and adjusting bolt pair to adapt to different types of plum screws.

[0011] 3. By rotating the wrench handle to turn the block, the wrench disk is driven to rotate, and the plum bolt can be turned without direct hand tightening, which reduces labor intensity and increases safety.

[0012] 4. The utility model can increase the tightening force, so that the equipment will not have safety accidents caused by insufficient tightening during operation, thus ensuring the normal production. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the structure of the utility model.

[0014] Figure 2 It is a schematic diagram of the disassembly structure of the utility model.

[0015] Among them: 1. wrench plate; 2. slide groove; 3. slide block; 4. adjusting bolt pair; 5. pull rod; 6. clamping block; 7. clamping sleeve; 8. wrench handle; 9. clamping groove. DETAILED DESCRIPTION

[0016] The utility model will now be further described in detail with reference to the accompanying drawings.

[0017] like Figure 1-2 As shown, an adjustable plum screw wrench includes a wrench plate 1, a plurality of slide grooves 2 are provided on the wrench plate 1, a slider 3 is slidably connected to the slide groove 2, an adjusting bolt pair 4 passing through the slide groove 2 and the slider 3 is passed through the slider 3, a pulling rod 5 is welded to the bottom end of the slider 3, a clamping block 6 is welded to the center of the top of the wrench plate 1, a clamping sleeve 7 is sleeved on the clamping block 6, and a wrench handle 8 is welded to the top of the clamping sleeve 7.

[0018] The slide groove 2 is in the shape of a long strip, and there are four slide grooves 2. The longitudinal center line of the slide groove 2 is located on the diameter line of the wrench plate 1. The four slide grooves 2 are arranged in an array with the central axis of the wrench plate 1 as the axis. The slide groove 2 is used to accommodate the pull rod 5 and the adjusting bolt pair 4, so that the slider 3 can slide in the slide groove 2.

[0019] The width of the slider 3 is greater than the width of the slide slot 2. The slider 3 is located above the slide slot 2. The trigger rod 5 is welded to the bottom of the slider 3 and passes through the slide slot 2. When the slider 3 slides on the slide slot 2, the distance between the trigger rods 5 is adjusted so that the trigger rods 5 can use different types of plum screws. The trigger rod 5 is used to be stuck in the concave part of the plum screw, so that the plum screw can be stuck.

[0020] The block 6 is square or hexagonal, and a slot 9 is provided at the bottom of the sleeve 7. The shape of the slot 9 matches the outer contour of the block 6, and the sleeve 7 is sleeved on the block 6 through the slot 9. The block 6 is used to clamp the sleeve 7, and when the wrench handle 8 is turned, the wrench plate 1 is driven to rotate.

[0021] The working principle of the utility model is:

[0022] When in use, first loosen the adjusting bolt pair 4, slide the slider 3 on the slide slot 2, and make the lever 5 stuck in the concave part of the plum screw. Then tighten the adjusting bolt pair 4 to fix the slider 3. After all four sliders 3 are stuck in the plum screw and the adjusting bolt pair 4 are tightened, clamp the sleeve 7 on the clamping block 6, and turn the lever handle 8 to drive the wrench plate 1 to rotate, so as to achieve the purpose of screwing the plum screw. When screwing plum screws of different sizes, just readjust the position of the lever 5.
