Description

Technical Field

[0001] This utility model belongs to the field of maintenance tool technology, specifically relating to a press-type adjustable wrench. Background Technology

[0002] Wrenches are common maintenance tools, often used for installing or removing workpieces. For example, the wrench head is used to clamp bolts and nuts, and then tightened or loosened by turning. Common wrenches can be divided into fixed and adjustable types. Fixed wrenches have a fixed clamping size, requiring different head sizes to fit different workpiece sizes. Adjustable wrenches, on the other hand, have an adjustable head. Rotating the stud moves one of the clamping parts, changing the distance between the two clamping parts to accommodate different workpiece sizes. However, adjusting the wrench head clamping size by rotating the stud is insufficient and cumbersome. Therefore, it is necessary to propose a new type of adjustable wrench. Utility Model Content

[0008] The paddle engages with the transmission assembly, with one end of the paddle located outside the housing. The paddle is rotatably connected to the housing. Pressing the paddle rotates the transmission assembly, causing the movable part to move toward the fixed part. The housing contains a first elastic element, whose elastic force always causes the paddle to rotate away from the handle. The housing also contains a clearance groove to avoid the movement of the paddle.

[0009] The reset member cooperates with the transmission assembly, and a portion of the reset member is located outside the housing; pressing the reset member to move it into the housing can cause the movable part to move away from the fixed part to complete the opening and reset of the clamping assembly; a second elastic element is provided inside the housing, and the elastic force of the second elastic element always causes the reset member to move out of the housing.

[0010] In a preferred embodiment of the present invention, the outer shell is provided with a sliding groove on the side facing the clamping assembly, and the sliding groove extends along the moving direction of the movable part; the movable part passes through the sliding groove and connects to the transmission assembly, or a portion of the transmission assembly passes through the sliding groove and connects to the movable part.

[0012] Pressing the reset member can cause the drive member and the locking member to separate from the displacement member.

[0013] Preferably, the paddle has an intermediate component, one side of which engages with the drive component, and the one-way limiting structure is disposed between the drive component and the intermediate component; the paddle has a slot for limiting the rotation of the intermediate component relative to the paddle, the intermediate component is inserted into the slot and can move laterally in the slot; the housing has a fourth elastic element, the elastic force of which always causes the intermediate component and the drive component to move toward the side closer to the reset component.

[0014] Preferably, the locking member is located below the driving member; the housing is provided with a blocking part to prevent the locking member from rotating downward; under normal conditions, one end of the locking member is embedded in the rack of the displacement member; a fifth elastic element is provided between the locking member and the housing, and the elastic force of the fifth elastic element always causes the locking member to move towards the side closer to the reset member.

[0015] In a preferred embodiment of this utility model, the reset member is disposed on the side of the housing.

[0016] In a preferred embodiment of the present invention, the paddle extends obliquely, and one end of the paddle located outside the housing is positioned above the housing.

[0017] In a preferred embodiment of this utility model, the outer shell is in the shape of a disc.

[0018] In a preferred embodiment of this utility model, the handle is ring-shaped.

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

[0021] This utility model's push-button adjustable wrench allows for adaptation to different workpieces by adjusting the clamping dimensions between the fixed and movable parts, thus increasing the wrench's applicability. During operation, the transmission component drives the movable part to move closer to the fixed part in stages. Combined with the push-button operation, this effectively improves the wrench's ease of use and makes operation simple and quick. Especially compared to the traditional adjustment method of rotating the stud, this utility model's push-button operation is more convenient, safer, and provides a better user experience.

[0022] Pressing the end of the paddle protruding from the housing causes it to rotate, driving the transmission assembly to move the movable part one level closer to the fixed part, completing one adjustment of the movable part. Releasing the paddle causes it to rotate in the opposite direction and return to its original position under the elastic force of the first elastic element. To further reduce the distance between the movable and fixed parts, simply press the paddle repeatedly, moving it closer to the fixed part step by step until the clamping size meets the requirements. To move the movable part away from the fixed part and fully return it to its maximum open state, press the reset component inside the housing. After pressing, the reset component moves outward under the elastic force of the second elastic element, restoring its initial position. This invention uses a pressing method for both adjusting and resetting the clamping size, making operation simple and convenient, and providing a new tool for maintenance and construction.

[0035] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this 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.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0037] See Figures 1-6 This embodiment discloses a press-type adjustable wrench, including a handle 1, a clamping assembly 3, and an adjusting assembly 2. The adjusting assembly 2 is connected to one end of the handle 1, and the clamping assembly 3 is connected to the side of the adjusting assembly 2 away from the handle 1.

[0038] The clamping assembly 3 in this embodiment includes a fixed part 302 and a movable part 301. The fixed part 302 and the movable part 301 are arranged opposite to each other. The clamping size can be adjusted by adjusting the distance between the fixed part 302 and the movable part 301.

[0039] The adjustment assembly 2 in this embodiment includes a housing 201, a paddle 202, a reset member 2010, and a transmission assembly for gradually moving the movable part 301 closer to the fixed part 302. The transmission assembly is located inside the housing 201, the fixed part 302 is fixed to the housing 201, and the movable part 301 is connected to the transmission assembly; one end of the handle 1 is connected to the housing 201. The paddle 202 cooperates with the transmission assembly, and one end of the paddle 202 is located outside the housing 201. The paddle 202 is rotatably connected to the housing 201. Pressing the paddle 202 rotates the transmission assembly, causing the movable part 301 to move towards the fixed part 302. The outer casing 201 contains a first elastic element 206. The elastic force of the first elastic element 206 always causes the paddle 202 to rotate away from the handle 1. The first elastic element 206 can be a spring. The main function of the first elastic element 206 is to reset the paddle 202. In order to allow the paddle 202 to rotate smoothly when pressed, the outer casing 201 is provided with a relief groove 20102 to avoid the movement of the paddle 202. In this embodiment, the reset member 2010 cooperates with the transmission assembly, and part of the reset member 2010 is located outside the outer casing 201. Pressing the reset member 2010 to move it into the outer casing 201 can cause the movable part 301 to move away from the fixed part 302 to complete the opening and reset of the clamping assembly 3. The outer casing 201 contains a second elastic element, which can be a spring. The elastic force of the second elastic element always causes the reset member 2010 to move out of the outer casing 201.

[0040] Pressing the end of the paddle 202 extending from the housing 201 causes it to rotate, driving the transmission assembly to move the movable part 301 one step closer to the fixed part 302, completing one adjustment of the movable part 301. Releasing the paddle 202 causes it to rotate in the opposite direction and reset under the elastic force of the first elastic element 206. When it is necessary to further reduce the distance between the movable part 301 and the fixed part 302, simply press the paddle 202 repeatedly, causing it to gradually move closer to the fixed part 302 until the clamping size meets the requirements. When it is necessary to move the movable part 301 away from the fixed part 302 and fully reset it to its maximum open state, press the reset member 2010 into the housing 201. After pressing, the reset member 2010 moves outward from the housing 201 under the elastic force of the second elastic element, restoring its initial position.

[0041] In this embodiment, the outer casing 201 is provided with a sliding groove on the side facing the clamping assembly 3. The sliding groove extends along the moving direction of the movable part 301. The movable part 301 passes through the sliding groove and is connected to the transmission assembly, or a part of the transmission assembly passes through the sliding groove and is connected to the movable part 301.

[0042] Furthermore, the transmission assembly in this embodiment also includes a displacement component 204, a driving component 203, and a locking component 205. The displacement member 204 is movably disposed within the housing 201 and connected to the movable part 301. The displacement member 204 is provided with a rack 2041 extending along the moving direction of the movable part 301. The driving member 203 is provided with gear teeth that mesh with the rack 2041. The driving member 203 is connected to the paddle 202. A one-way limiting structure is provided between the paddle 202 and the driving member 203. When the paddle 202 is pressed, it can drive the driving member 203 to rotate. When the first elastic element 206 drives the paddle 202 to rotate in the opposite direction, the position of the driving member 203 is maintained. A third elastic element 207 is provided between the displacement member 204 and the housing 201. The elastic force of the third elastic element 207 always causes the displacement member 204 to move away from the fixed part 302. The third elastic element 207 can be a spring. Under normal conditions, the locking member 205 keeps the displacement member 204 from moving away from the fixed part 302. In this embodiment, the reset member 2010 is used to drive the movement of the drive member 203 and the locking member 205 to separate from the displacement member 204, so that the displacement member 204 can be automatically reset under the action of the third elastic element 207 without obstruction, and complete the full opening of the movable part 301 and the fixed part 302. During operation, pressing the reset member 2010 can cause the drive member 203 and the locking member 205 to separate from the displacement member 204.

[0043] In this embodiment, a metal part 4 is provided on the opposite side of the fixed part 302 and the movable part 301 to enhance the reliability of the fixed part 302 and the movable part 301 when clamping the workpiece. The displacement member 204 in the transmission assembly of this embodiment is also made of metal. Therefore, the metal part 4 on the movable part 301 and the displacement member 204 can be integrated for ease of manufacturing and assembly. Of course, the connection between the movable part 301 and the displacement member 204 can also be achieved in other ways, and the material can be flexibly selected, not limited to the description in this embodiment, as long as the connection allows for synchronous movement.

[0044] In this embodiment, the driving component 203 can be a gear or other toothed structure. To facilitate the connection between the paddle 202 and the driving component 203, the driving component 203 in this embodiment includes a toothed portion 2031 and a connecting portion 2032. The toothed portion 2031 cooperates with the rack 2041 on the displacement component 204, and the connecting portion 2032 is used to cooperate with the paddle 202.

[0045] Furthermore, the unidirectional limiting structure of this embodiment includes a first helical tooth 2033 and a second helical tooth 20111. The first helical tooth 2033 and the second helical tooth 20111 rotate in opposite directions. The first helical tooth 2033 and the second helical tooth 20111 are respectively disposed on the connecting part 2032 of the driving member 203 and the paddle 202 and cooperate with each other. By setting the first helical tooth 2033 and the second helical tooth 20111, when the paddle 202 is pressed to rotate, it can drive the driving member 203 to rotate synchronously, thereby realizing the movement of the displacement member 204 through cooperation with the rack 2041, and finally realizing the movement of the movable part 301. When the paddle 202 is released, under the elastic force of the first elastic element 206, the paddle 202 rotates in the opposite direction to reset. Since the first helical tooth 2033 and the second helical tooth 20111 can rotate relative to each other in this direction, the reverse rotation of the paddle 202 does not drive the drive member 203, thus realizing the independent reset of the paddle 202. The drive member 203 and the displacement member 204 are not affected.

[0046] The unidirectional limiting structure of this embodiment can adopt other methods in the prior art. For example, as another implementation, the unidirectional limiting structure can be a ratchet mechanism, specifically, a ratchet can be provided on the connecting part 2032 and a pawl can be provided on the pawl 202.

[0047] In this embodiment, the paddle 202 is provided with an intermediate member 2011. One side of the intermediate member 2011 cooperates with the drive member 203. A one-way limiting structure is provided between the drive member 203 and the intermediate member 2011. The paddle 202 is provided with a slot 2021 for limiting the rotation of the intermediate member 2011 relative to the paddle 202. The intermediate member 2011 is inserted into the slot 2021 and can move laterally in the slot 2021. A fourth elastic element 208 is provided inside the outer shell 201. The fourth elastic element 208 can be a spring. The elastic force of the fourth elastic element 208 always causes the intermediate member 2011 and the drive member 203 to move towards the side closer to the reset member 2010. To achieve the cooperation between the intermediate component 2011 and the slot 2021, the slot 2021 in this embodiment is approximately T-shaped, and the contour of the side of the intermediate component 2011 facing the slot 2021 is matched. This restricts the rotation of the intermediate component 2011 relative to the lever 202, while allowing the lever 202 to rotate synchronously with the intermediate component 2011. Furthermore, the fourth elastic element 208 in this embodiment is a spring, disposed between the intermediate component 2011 and the outer casing 201.

[0048] The intermediate component 2011 ensures that when the reset component 2010 is pressed, causing the drive component 203 to separate from the displacement component 204, the drive component 203 and the intermediate component 2011 move laterally, compressing the fourth elastic element 208. This keeps the paddle 202 unaffected, and the slot 2021 also guides the intermediate component 2011. When the external force on the reset component 2010 is removed, the elastic force of the fourth elastic element 208 takes effect, causing the intermediate component 2011 and the drive component 203 to move back to their normal positions. The gear teeth on the drive component 203 then re-engage with the rack 2041 on the displacement component 204. Because the intermediate component 2011 ensures that the paddle 202 is unaffected when the movable part 301 and the displacement component 204 are reset, the position of the frequently used paddle 202 remains relatively stable, which helps improve product stability and service life.

[0049] In another embodiment, the structure between the paddle 202 and the drive member 203 can be simplified, eliminating the need for the intermediate member 2011. When the reset member 2010 is pressed, causing the drive member 203 to move laterally, the parts of the paddle 202 that engage with the drive member 203 can move laterally synchronously, achieving separation of the drive member 203 from the displacement member 204 and completing the reset action. To achieve this, the paddle 202 can be made of a material with certain restorative properties, such as a spring or plastic.

[0050] See Figures 2-5In this embodiment, the locking member 205 is located below the driving member 203; the housing 201 is provided with a blocking part 20101 to prevent the locking member 205 from rotating downward; under normal conditions, it can be understood that when the locking member 205 is not acted upon by the reset member 2010, one end of the locking member 205 is embedded in the rack 2041 of the displacement member 204; a fifth elastic element 209 is provided between the locking member 205 and the housing 201, and the fifth elastic element 209 can be a spring, the elastic force of the fifth elastic element 209 always causes the locking member 205 to move towards the side closer to the reset member 2010. By using the locking member 205 to lock the rack 2041 on the displacement member 204, the displacement member 204 can only move upward, and cannot move downward due to the blocking of the locking member 205. When the reset member 2010 is pressed, causing the locking member 205 to compress the fifth elastic element 209, the locking member 205 disengages from the rack 2041. At this time, the displacement member 204 can move downward (i.e., away from the fixing part 302) under the elastic force of the third elastic element 207, completing the reset. In this embodiment, the blocking part 20101 is located inside the outer shell 201 and can be integrally formed with the outer shell 201 or with the reset member 2010. Its purpose is to prevent the locking member 205 from rotating downward. In this embodiment, the blocking part 20101 is connected to the reset member 2010.

[0051] Furthermore, the length of the rack 2041 in this embodiment can be flexibly set according to actual needs. Generally, when the lowest tooth of the rack 2041 is supported by the locking member 205, the fixed part 302 and the movable part 301 still have a certain distance and are not closed together, so that the clamping assembly 3 has a minimum clamping size, which can also be called a safety distance. By setting a safety distance, accidental pinching injury to the user can be effectively prevented, especially when children use it. When continuously pressing the lever 202, they may easily overlook the distance between the fixed part 302 and the movable part 301. Therefore, setting a safety distance can improve the safety performance of the wrench product in this embodiment.

[0052] In this embodiment, the reset member 2010 is disposed on the side of the housing 201. Specifically, protrusions are provided on the inner side of the reset member 2010 at corresponding positions of the driving member 203 and the locking member 205, so as to effectively press these two components to promote lateral movement, thereby achieving the purpose of resetting the movable part 301 after separating from the displacement member 204. The aforementioned second elastic element is used for resetting the reset member 2010. A fourth elastic element 208 and a fifth elastic element 209 are respectively provided at the driving member 203 and the locking member 205. Their reset directions for the driving member 203 and the locking member 205 are the same as the reset direction of the reset member 2010. Therefore, the use of the second elastic element can be omitted, and the reset member 2010 can be reset by the elastic force of the fourth elastic element 208 and the fifth elastic element 209.

[0053] The paddle 202 extends at an angle, with one end of the paddle 202 located outside the housing 201 and above the housing 201. This makes the end of the paddle 202 on the housing 201 easier to press and move. For example, while holding the handle 1, the thumb can press the paddle 202, causing it to rotate to one side of the handle 1, thereby moving the movable part 301 and changing the size of the clamping assembly 3. This operating position is more convenient and easier to use.

[0054] The outer shell 201 is disc-shaped. Designing the outer shell 201 in a disc shape facilitates the adjustment of component 2, providing ample internal space to accommodate various parts. Furthermore, in this embodiment, the paddle 202 extends above the outer shell 201. When the paddle 202 is turned, pressing it towards the handle 1 causes it to rotate, and the rotation trajectory of the paddle 202 matches the outer contour of the disc, making operation more convenient and smooth. On the other hand, the disc-shaped outer shell 201 adds an interesting element to the product structure. The fixed part 302 and the movable part 301 can be combined to define the outer shell 201 as the head of an animal, the fixed part 302 and the movable part 301 as the mouth of an animal, and an ear of an animal can be added to the top of the outer shell 201, along with a corresponding pattern design, making the product's shape animalistic and suitable for early childhood education activities. For example, the wrench product of this embodiment can be designed with the shape of a hippopotamus in mind, with the paddle 202 extending from the end of the outer shell 201 as one of the ears.

[0055] The handle 1 is ring-shaped. This makes it easy to carry the wrench. When using it, you can hold the upper part of the handle 1 and then use your thumb to press the lever 202 to adjust the clamping size. Of course, it can also be used with both hands. This embodiment only provides a conventional way of use, but it is not limited to this.

[0056] Furthermore, in this embodiment, the handle 1 extends along its length to form a ring structure of a certain length, which makes it easier to grip and ensures that the handle 1 has sufficient length. This allows for efficient use of the lever principle when twisting workpieces, saving effort and improving the user experience. Simultaneously, this handle 1, together with the disc-shaped outer shell 201 and the clamping assembly 3, can form an animal-like shape. In actual production, decorative parts, such as animal feet or tails, can be placed at different positions on the handle 1. The inner side of the handle 1 in this embodiment is provided with a hand guard 101, which includes multiple spaced protrusions arranged along the inner side of the handle 1. The protrusions in this embodiment can be made of silicone or other materials with a good feel, aiming to improve the comfort of gripping the handle 1.

[0057] As another implementation, the transmission assembly of this embodiment can refer to the prior art to select various transmission structures to achieve the step-by-step movement of the movable part 301, so as to achieve the purpose of moving the movable part 301 one level with each press of the paddle 202. The form of the reset member 2010 and the locking member 205 can also adopt different implementation methods.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
