Description

Technical Field

[0001] This utility model relates to the field of handle technology, and in particular to a quick-release handle. Background Technology

[0002] Quick-release handles, as a convenient connection and separation mechanism, are widely used in various fields such as equipment, tools, and devices to quickly lock and release components.

[0003] The quick-release handle structures commonly found on the market typically employ a spring pin / button pin locking mechanism. By pressing the button or pin on the handle, the spring force is overcome, causing the sleeve to retract and release. While this method achieves quick release, it requires considerable force to hold the button or pin in place, as the fingers need to overcome the spring force, making it not effortless.

[0004] However, existing technologies also suffer from structural complexity. Some designs require the introduction of more parts (such as additional springs, buttons, locking rings, etc.) to achieve quick-release functionality, which increases manufacturing costs and structural complexity. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release handle that is easy and quick to operate and has a simple and reliable structure.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-release handle, including a connecting rod and a sleeve, the sleeve being sleeved on the connecting rod, a clamping member being provided inside the connecting rod, the clamping member including a pressing part and a locking part, the pressing part causing the locking part to have a locked state at least partially exposed on the surface of the sleeve, and an unlocked state hidden inside the sleeve, pressing the pressing part switches the locking part between the locked state and the unlocked state; the pressing part can retract toward the inside of the sleeve under the action of external force, and the retraction direction is not the same as the unlocking direction of the locking part.

[0007] By adopting the above technical solution, this structure overcomes the shortcomings of traditional handle structures, which can only disassemble the sleeve and connecting rod by continuously pressing the locking part (spring pin) exposed on the surface of the sleeve, resulting in less effort. The disassembly and assembly operations are faster.

[0008] A further feature of this invention is that a driving member abuts against the lower part of the clamping member, and the driving member converts the displacement of the pressing part along the X direction into the displacement of the locking part along the Y direction.

[0009] By adopting the above technical solution and setting a driving component, when the pressing part is pressed, the locking part moves away from the sleeve, and when the pressing part is released, the locking part can be reset. This structure overcomes the shortcomings of the traditional handle structure, which can only disassemble the sleeve and connecting rod by continuously pressing the locking part (spring pin) exposed on the surface of the sleeve, resulting in less effort. The disassembly and assembly operations are more effortless.

[0010] A further feature of this invention is that the driving component is a guide post disposed on the inner wall of the connecting rod, the guide post is provided with a guide surface, and the clamping component is guided and engaged with the guide surface to form a displacement path for the constraint locking part to move closer to / away from the sleeve.

[0011] By adopting the above technical solution, the locking part of the clamping part abuts against the guide post. When the pressing part is pressed, the locking part moves away from the sleeve under the guidance of the guide surface. When the pressing part is released, the locking part resets under the guidance of the guide surface, thereby reaching the locked position. This effectively reduces the pneumatic force applied to the pressing part, thus achieving the effect of labor-saving operation.

[0012] A further feature of this invention is that the guide post is a protrusion formed on the inner wall of the connecting rod, and the guide surface is the end face of the protrusion facing the center of the connecting rod, and is configured as an outwardly convex arc-shaped surface.

[0013] By adopting the above technical solution, the effect of quick assembly and disassembly is achieved, and the pneumatic force applied to the pressing part is effectively reduced, making operation easier.

[0014] A further feature of this invention is that the X direction is perpendicular to the Y direction.

[0015] By adopting the above technical solution, when the X direction is perpendicular to the Y direction, it is easier to press the pressing part.

[0016] A further feature of this invention is that the locking part is a first protrusion on the clamping member, the connecting rod has a first through hole corresponding to the first protrusion, the sleeve has a second through hole corresponding to the first through hole, the first protrusion and the second through hole together constrain the displacement path of the sleeve, the pressing part is a second protrusion on the clamping member, the connecting rod has a third through hole corresponding to the second protrusion, and pressing the second protrusion causes the first protrusion to form a displacement path away from the second through hole.

[0017] By adopting the above technical solution, the first protrusion is inserted into the second through hole of the sleeve to fix the sleeve and the connecting rod. The third through hole allows the second protrusion to be exposed on the surface of the connecting rod, which facilitates pressing operation. The structure is simple and reliable.

[0018] A further feature of this invention is that the clamping member is an X-shaped clamp, the clamping member includes an upper clamping foot and a lower clamping foot, and the driving member abuts against the underside of each clamping foot of the clamping member.

[0019] By adopting the above technical solution, a driving component is provided under each clamping foot, and each driving component drives the clamping foot to move simultaneously, greatly reducing the force applied to the pressing part and making the operation more labor-saving.

[0020] A further feature of this invention is that the upper clamping foot and the lower clamping foot are symmetrical about the central axis of the clamping member, and the second protrusion is disposed on the central axis of the clamping member.

[0021] By adopting the above technical solution, the second protrusion is set on the central axis of the clamping part. When the pressing part is pressed, the driving force on each clamping foot is more uniform, making the movement of the clamping foot smoother.

[0022] A further feature of this invention is that the first protrusion is disposed at the end of the upper clamping foot, and the lower clamping foot abuts against the inner wall of the connecting rod.

[0023] By adopting the above technical solution, when the sleeve and the connecting rod are engaged by the first protrusion of the upper clamp, the lower clamp abuts against the inner wall of the connecting rod to form friction. The double fixing effect makes the handle less likely to rotate or come off during use, making it more stable to use.

[0024] A further feature of this invention is that the connecting rod is provided with an installation part, a spring buckle is provided on the outer wall of the installation part, and a plurality of ribs are provided circumferentially on the outer wall of the installation part.

[0025] By adopting the above technical solution, the installation unit can be connected to an external mounting base with a cleaning function. The mounting base is equipped with a snap-fit ​​device that cooperates with the spring clip and the rib. By setting the spring clip and the rib, it is convenient to fix the mounting base.

[0026] In summary, this utility model has the following beneficial effects:

[0027] 1. A clamping component is provided inside the connecting rod. The clamping component includes a pressing part and a locking part. The pressing part causes the locking part to have a locked state where at least part of it is exposed on the surface of the sleeve, and an unlocked state where it is hidden inside the sleeve. Pressing the pressing part switches the locking part between the locked and unlocked states. Under the action of external force, the pressing part can retract toward the inside of the sleeve, and the retraction direction is not the same as the unlocking direction of the locking part. This structure overcomes the shortcomings of traditional handle structures, which can only achieve the disassembly of the sleeve and connecting rod by continuously pressing the locking part (spring pin) exposed on the surface of the sleeve, resulting in a labor-intensive operation. The disassembly and assembly operations are faster.

[0028] 2. A driving component is abutted below the clamping component. The driving component converts the displacement of the pressing part along the X direction into the displacement of the locking part along the Y direction. When the pressing part is pressed, the locking part moves away from the sleeve. When the pressing part is released, the locking part can be reset, making the disassembly and assembly operations easier. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] A quick-release handle, such as Figure 1-5As shown, the device includes a connecting rod 1 and a sleeve 2. The sleeve 2 is sleeved on the connecting rod 1. A clamping member 3 is provided inside the connecting rod 1. The clamping member 3 includes a pressing part and a locking part. The pressing part causes the locking part to have a locked state in which at least part of it is exposed on the surface of the sleeve 2, and an unlocked state in which it is hidden inside the sleeve 2. Pressing the pressing part switches the locking part between the locked state and the unlocked state. The pressing part can retract toward the sleeve 2 under the action of external force, and the retraction direction is not the same as the unlocking direction of the locking part. The locking state refers to the locking part extending from the inside of the connecting rod 1 to the outside of the sleeve 2 and engaging with the sleeve 2, thereby fixing the sleeve 2 and the connecting rod 1 in a fixed connection. The unlocking state refers to the locking part retracting back into the connecting rod 1 and disengaging from the sleeve 2, thereby making the sleeve 2 and the connecting rod 1 in a movable and detachable state. When the pressing part is pressed, it moves the locking part away from the sleeve 2 to achieve the unlocking state. When the pressing part is released, the locking part resets, and a portion of the reset locking part protrudes from the surface of the sleeve 2 and engages with the sleeve 2 to achieve the locking state. The retraction direction of the pressing part and the unlocking direction of the locking part are inconsistent, meaning that the pressing direction of the pressing part and the movement direction of the locking part are not on the same axis. This structure overcomes the shortcomings of traditional handle structures, which can only achieve the disassembly of the sleeve 2 and the connecting rod 1 by continuously pressing the locking part (spring pin) exposed on the surface of the sleeve 2, resulting in less effort. The disassembly and assembly operations are faster.

[0038] Preferably, a driving member abuts against the lower part of the clamping member 3, the driving member converting the displacement of the pressing part along the X direction into the displacement of the locking part along the Y direction. X direction, such as... Figure 4 As shown, its configuration is perpendicular to the axis of connecting rod 1, in the Y direction, as... Figure 4 As shown, its configuration is perpendicular to the axis of connecting rod 1, and the X direction is perpendicular to the Y direction. The above-mentioned scheme in which the X direction and Y direction are perpendicular is only one of the preferred implementation methods in this embodiment, but it is not limited to the X direction and Y direction necessarily being perpendicular to each other. The X direction and Y direction can also be set at an angle and not perpendicular, or the X direction and Y direction can be parallel to each other and not on the same axis. All of these can achieve the effect of easy and quick disassembly and assembly of sleeve 2 and connecting rod 1 with simple and reliable structure. By setting a driving component, when the pressing part is pressed, the locking part moves away from sleeve 2, and when the pressing part is released, the locking part can be reset. This structure overcomes the defect of the traditional handle structure that can only achieve disassembly of sleeve 2 and connecting rod 1 by continuously pressing the locking part (spring pin) exposed on the surface of sleeve 2, which is not labor-saving. The disassembly and assembly operation is more labor-saving.

[0039] Preferably, the driving component is a guide post 13 disposed on the inner wall of the connecting rod 1. The guide post 13 is provided with a guide surface 131. The clamping member 3 is guided and engaged with the guide surface 131 to form a displacement path for the restraining locking part to move closer to / away from the sleeve 2. The locking part of the clamping member 3 abuts against the guide post 13. When the pressing part is pressed, the locking part moves away from the sleeve 2 under the guidance of the guide surface 131. When the pressing part is released, the locking part resets under the guidance of the guide surface 131, thereby reaching the locked position. This effectively reduces the pneumatic force applied to the pressing part, thereby achieving the effect of labor-saving operation.

[0040] Preferably, the guide post 13 is a protrusion formed on the inner wall of the connecting rod 1, and the guide surface 131 is the end face of the protrusion facing the center of the connecting rod 1, and is configured as an outwardly convex arc-shaped surface. The inclination direction of the arc-shaped surface gradually approaches the Y direction from the X direction. The above-mentioned inclination direction of the arc-shaped surface is only one preferred embodiment of this example, but it is not limited to the inclination direction of the arc-shaped surface necessarily being from the X direction to the Y direction. It can also be from the axis of the connecting rod 1 to the X direction. The directions described above not only refer to the direction of the same axis, but also include the direction parallel to the axis. The clamping member 3 is made of an elastic material, such as plastic or metal that deforms under force. The guide posts 13 are preferably symmetrically arranged on the inner wall of the connecting rod 1. When the pressing part is pressed, the locking part is on the guide surface 131. Under the guidance, it moves away from the sleeve 2. Since the guide surface 131 is a convex part, when the locking part moves to the low point of the convex part, the sleeve 2 and the clamping member 3 are unlocked. Since the clamping member 3 is made of elastic material, under the compression of the two symmetrical convex parts, the clamping member 3 is in a contracted state and deforms. At this time, when the pressing part is released, the clamping member 3 will generate elastic force in the process of returning to its original shape. Under the action of elastic force, the clamping member 3 resets along the guide surface 131, and the sleeve 2 and the connecting rod 1 are locked. This achieves the effect of quick disassembly and assembly and effectively reduces the pneumatic force applied to the pressing part, making the operation labor-saving.

[0041] Preferably, the locking part is a first protrusion 31 provided on the clamping member 3, the connecting rod 1 has a first through hole 11 corresponding to the first protrusion 31, and the sleeve 2 has a second through hole 21 corresponding to the first through hole 11. The first protrusion 31 and the second through hole 21 together constrain the displacement path of the sleeve 2. The pressing part is a second protrusion 32 provided on the clamping member 3, and the connecting rod 1 has a third through hole 12 corresponding to the second protrusion 32. Pressing the second protrusion 32 causes the first protrusion 31 to form a displacement path away from the second through hole 21. Preferably, there are two first protrusions 31, symmetrically arranged on the locking part. The first protrusions 31 are inserted into the second through hole 21 of the sleeve 2 to fix the sleeve 2 to the connecting rod 1. The third through hole 12 allows the second protrusions 32 to be exposed on the surface of the connecting rod 1, which facilitates the pressing operation and makes the structure simple and reliable.

[0042] The basic working principle of this utility model is as follows: When the second protrusion 32 is pressed, the first protrusion 31 moves away from the sleeve 2 under the guidance of the guide surface 131. Since the guide surface 131 is a convex part, when the first protrusion 31 moves to the lowest point of the convex part, the sleeve 2 and the X-shaped clamp are unlocked. Since the X-shaped clamp is made of elastic material, under the compression of the two symmetrical protrusions, the clamping arms of the X-shaped clamp are in a contracted state and deform. When the second protrusion 32 is released, the clamping arms of the X-shaped clamp will generate elastic force in the process of returning to their original shape. Under the action of elastic force, the X-shaped clamp resets along the guide surface 131, and the sleeve 2 and the connecting rod 1 are locked. This achieves the effect of quick disassembly and assembly and effectively reduces the applied pneumatic force, making the operation labor-saving.

[0043] Example 2:

[0044] A quick-release handle, such as Figure 2 As shown, the difference between this embodiment and specific embodiment one is that:

[0045] The clamping member 3 is an X-shaped clamp, comprising an upper clamping leg 33 and a lower clamping leg 34. The driving member abuts against the underside of each clamping leg of the clamping member 3. Preferably, there are two upper clamping legs 33 and two lower clamping legs 34, symmetrically arranged on the clamping member 3. A driving member is provided under each clamping leg, and each driving member simultaneously drives the clamping leg to move, greatly reducing the force applied to the pressing part and making the operation more effortless.

[0046] Preferably, the upper clamping foot 33 and the lower clamping foot 34 are symmetrical about the central axis of the clamping member 3, and the second protrusion 32 is disposed on the central axis of the clamping member 3. With the second protrusion 32 disposed on the central axis of the clamping member 3, when the pressing part is pressed, the driving force on each clamping foot is more uniform, making the movement of the clamping foot smoother.

[0047] Preferably, the first protrusion 31 is disposed at the end of the upper clamping foot 33, and the lower clamping foot 34 abuts against the inner wall of the connecting rod 1. When the sleeve 2 and the connecting rod 1 are engaged by the first protrusion 31 of the upper clamping foot 33, the lower clamping foot 34 abuts against the inner wall of the connecting rod 1 to form friction. The double fixing effect makes the handle less likely to rotate or come off during use, making it more stable to use.

[0048] In another preferred embodiment, the connecting rod 1 is provided with a mounting portion 14, and a spring buckle 141 protrudes from the outer wall of the mounting portion 14. A plurality of ribs 142 are circumferentially formed on the outer wall of the mounting portion 14. The mounting portion 14 can be externally connected to a mounting seat (not shown in the figure) with a cleaning function. The mounting seat is provided with a snap-fit ​​device that cooperates with the spring buckle 141 and the ribs 142. This snap-fit ​​device can be a slot corresponding to the spring buckle 141 and a groove corresponding to the ribs 142. By having the spring buckle 141 snap into the slot and the ribs 142 snap into the groove, the mounting seat can be easily fixedly connected. The above description is only a preferred embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the claims of this utility model patent application are included within the scope of this utility model patent application.
