Abstract
Description
Technical Field
[0001] This utility model relates to the field of manual hardware tools, and in particular to a hexagonal locking wrench that can be quickly adjusted. Background Technology
[0002] Currently, hexagonal nuts, as commonly used standard fasteners, are widely used in the machinery and construction industries, driving the consumer market for related disassembly tools. Adjustable wrenches, due to their built-in adjustment function, can handle various sizes of hexagonal nuts. Compared to ordinary hexagonal wrenches, these products are more popular with consumers. However, most current adjustable wrenches use a ratchet to adjust the clamping size, such as the one with publication number CN212887339U, named "An Adjustable Wrench with a Rotatable Tail with a Ratchet Function." Its structure has a regular adjustable wrench on one end and a ratchet wrench on the other. The adjustment process is time-consuming, slow, and inefficient. Therefore, there is a huge market demand for quickly adjustable hexagonal wrenches, and currently, there is no good solution to the above problems.
[0003] In summary, how to achieve rapid adjustment of hex wrenches has become a technical problem that urgently needs to be solved in the industry. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this utility model provides a quick-adjustable hexagonal locking wrench, which solves the problems of slow speed and low efficiency when adjusting the opening of previous hexagonal wrenches.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A quick-adjustable hexagonal locking wrench includes a housing. Inside the housing, guide grooves are provided on both sides. The top surface of each guide groove has a first obtuse-angled bevel. Wavy teeth are provided on both sides of the guide grooves. A top block and a push key are slidably mounted between the two guide grooves. The top block has a second obtuse-angled bevel at its head. The first and second obtuse-angled bevels cooperate to lock the hexagonal nut. Two spring plates are spaced apart at the rear of the push key. Clip grooves are provided on both sides of the push key. Clips are slidably mounted within the clip grooves. A clutch boss is provided at the bottom of the clip, cooperating with the two spring plates. The clutch boss drives the two spring plates to engage or disengage with the wavy teeth.
[0006] The tail of the guide groove extends through the tail of the outer casing, and a rear cover is installed at the tail of the outer casing.
[0007] The bottom of the top block is provided with a U-shaped groove and a blind hole, and the front end of the push key is provided with a U-shaped block and a frustum. The U-shaped block is fitted into the U-shaped groove, and the frustum is fitted into the blind hole.
[0008] The top block and the push key are respectively provided with protrusions that are slidably installed in the guide groove on both sides.
[0009] The outer side of the movable end of the spring sheet is provided with teeth that cooperate with the wave teeth.
[0010] The buckle slide groove is provided with a front gear groove and a rear gear groove. The front part of the buckle is provided with an elastic rod, and the front end of the elastic rod is provided with a locking protrusion that cooperates with the front gear groove and the rear gear groove.
[0011] The outer casing has a scale on one side, and the push button has a pointer corresponding to the scale.
[0012] The present invention adopts the above solution and has the following beneficial effects: By setting guide grooves inside the outer casing, a top block and a push key are slidably installed between the guide grooves. The push key drives the top block to move, so that the first and second obtuse-angled inclined surfaces cooperate to lock the hexagonal nut. The clutch boss at the bottom of the buckle can drive the two spring plates at the rear of the push key to move. When the clutch boss is between the two spring plates, it can spread the two spring plates apart, so that the teeth on the spring plates mesh with the wave teeth. At this time, the push key cannot slide, constraining the relative position of the push key and the top block in the outer casing, thereby locking the hexagonal nut for tightening. When the clutch boss disengages from between the two spring plates, the two spring plates move inward, and the teeth disengage from the wave teeth. At this time, the push key can slide back and forth, thereby driving the top block to slide quickly to adjust the opening amount, realizing the rapid adjustment of the hexagonal wrench and improving the ease of use of the hexagonal wrench.

[0019] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0020] like Figure 1-5 As shown, a quick-adjustable hexagonal locking wrench includes a housing 1. Inside the housing 1, guide grooves 2 are provided on both sides. The top surface of each guide groove 2 has a first obtuse-angled bevel 3. Wavy teeth 4 are provided on both sides of each guide groove 2. A top block 5 and a push key 6 are slidably installed between the two guide grooves 2. The head of the top block 5 has a second obtuse-angled bevel 7. The first obtuse-angled bevel 3 and the second obtuse-angled bevel 7 cooperate to lock the hexagonal nut. Two spring plates 8 are spaced apart at the rear of the push key 6. Clip grooves 9 are provided on both sides of the push key 6. Clips 10 are slidably installed within the clip grooves 9. A clutch boss 11 is provided at the bottom of the clip 10, cooperating with the two spring plates 8. The clutch boss 11 drives the two spring plates 8 to engage or disengage with the wavy teeth 4.
[0021] The tail of the guide groove 2 passes through the tail of the outer shell 1, so that the top block 5 and the push key 6 can pass through the guide groove 2 from the tail of the outer shell 1. The tail cover 12 is installed at the tail of the outer shell 1 to prevent the parts from sliding out.
[0022] The top block 5 has a U-shaped groove 13 and a blind hole 14 at its bottom, and the push key 6 has a U-shaped block 15 and a frustum 16 at its front end. The U-shaped block 15 is fitted into the U-shaped groove 13, and the frustum 16 is fitted into the blind hole 14, so that the top block 5 and the push key 6 are connected together.
[0023] The top block 5 and the push key 6 are respectively provided with protrusions 17 that are slidably installed in the guide groove 2 on both sides, which are used to limit the free swaying of the top block 5 and the push key 6 when they slide.
[0024] The outer side of the movable end of the spring plate 8 is provided with teeth 18 that cooperate with the wave teeth 4. The teeth 18 can engage or disengage with the wave teeth 4.
[0025] The latching groove 9 has a front gear slot 19 and a rear gear slot 20. The front of the latch 10 has an elastic rod 21, and the front end of the elastic rod 21 has a latching protrusion 22 that cooperates with the front gear slot 19 and the rear gear slot 20. When the latching protrusion 22 is in the rear gear slot 20 of the push key 6, the clutch protrusion 11 disengages from the two spring plates 8, and the push key 6 can slide back and forth, driving the top block 5 to quickly adjust the opening amount. When the latching protrusion 22 is in the front gear slot 19 of the push key 6, the clutch protrusion 11 is exactly locked in the middle of the two spring plates 8, opening the two spring plates 8, so that the teeth 18 on the spring plates 8 mesh with the wave teeth 4, and the push key 6 cannot slide.
[0026] The outer casing 1 has a scale 23 on one side, which corresponds to the size of the hexagonal nut. The push key 6 has a pointer 24 corresponding to the scale 23, which can quickly read the scale value.
[0027] Working principle: In use, first push the buckle 10 backward so that the locking protrusion 22 of the elastic rod 21 at the front of the buckle 10 is in the rear stop groove 20 of the push key 6. The clutch boss 11 disengages from the two spring plates 8, and the two spring plates 8 move inward. The teeth 18 disengage from the wave teeth 4 on both sides. At this time, the push key 6 can slide back and forth, thereby driving the top block 5 to slide quickly along the guide groove 2 to adjust the opening amount, realizing the quick adjustment of the hex wrench. After the adjustment is in place, push the buckle 10 forward so that the locking protrusion 22 of the elastic rod 21 at the front of the buckle 10 is in the front stop groove 19 of the push key 6. When the clutch boss 11 is between the two spring plates 8, it can open the two spring plates 8, so that the teeth 18 on the spring plates 8 engage with the wave teeth 4 on both sides. At this time, the push key 6 cannot slide, constraining the push key 6 and the top block 5 in the relative position of the outer shell 1. The hexagonal nut is locked by the first obtuse angle inclined surface 3 and the second obtuse angle inclined surface 7 for tightening operation.
[0028] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.
[0029] Any aspects of this utility model not described in detail are known to those skilled in the art.
