Description

Technical Field

[0001] This invention relates to the field of instrument handle technology, and in particular to a telescopic handle and a corresponding tool. Background Technology

[0002] Currently, for tools with a gripping function, such as snowplows, the handle is connected to the tube body. To accommodate users of different heights, the handle and tube body usually have a telescopic function, meaning the height can be adjusted. There are many types of adjustment structures available, such as the telescopic handle disclosed in CN214980796U. This includes a handle, one end of which is slidably connected to a tension switch. The handle has a locking seat that can be fixed to the tension switch. The other end of the handle is fixedly connected to a connecting sleeve. The connecting sleeve and the handle have interconnected cavities. A telescopic aluminum tube is slidably connected within the cavity. A groove is formed on the inner wall of the connecting sleeve. A telescopic switch is slidably connected within the groove. A telescopic steel ball is placed between the telescopic switch and the telescopic aluminum tube. A groove is formed on the telescopic aluminum tube. The telescopic switch has a concave-convex part that can press the telescopic steel ball into or release it from the groove. The tension switch is connected to the telescopic switch via a tension steel wire. This type of adjustment structure has the problem of inconvenience in use. The distance between the object of force application and the adjustment position is relatively far, making adjustment difficult. It is also difficult to achieve positioning and clamping during the adjustment process, and it is easy to slip during use. Summary of the Invention

[0003] The present invention aims to overcome the shortcomings of the prior art by providing a telescopic handle and corresponding tool to prevent slippage during use.

[0035] The embodiments of the present invention will be described in detail below. In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0036] Therefore, the detailed description of the embodiments of the present invention provided below is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] The terminology used herein is intended to explain the embodiments and is not intended to limit and / or restrict the invention.

[0038] Example 1

[0039] like Figures 1-3 As shown, the telescopic handle in this embodiment is mainly composed of a handle body 10, a tube 20, and an adjustment structure. The tube 20 is movably connected to the handle body 10 through the adjustment structure. Here, the handle body 10 is formed by splicing two half-shells.

[0040] In this text, the axial and radial directions refer to the axial and radial directions of the tube body 20.

[0041] Combination Figures 4-5 As shown, specifically, the adjustment structure includes a flip-up trigger 30 mounted on the handle body 10, a transmission body 40 mounted on the handle body 10, an elastic body 50 mounted between the transmission body 40 and the handle body 10, a locking body 60 connected to the transmission body 40, a second locking body 70 located on one side of the tube body 20 and arranged axially thereon, and an adjustment knob 90 connected to the transmission body 40.

[0042] The transmission body 40 is arranged radially along the tube 20 and passes through the tube 20. One end of the transmission body 40 is engaged with the trigger 30. The transmission body 40 includes a head 41 and a rod 42 connected together. The rod 42 passes through the tube 20 and is connected to the locking body 60. The head 41 is larger than the rod 42. The head 41 provides sufficient contact surface to cooperate with the trigger 30. Correspondingly, one end of the trigger 30 is rotatably connected to the handle body 10 through a shaft structure. By applying external force to the other end of the trigger 30, the trigger 30 can be rotated. The trigger 30 has a contact end 31 on the side facing the transmission body 40. The contact end 31 contacts and cooperates with the head 41 and can apply pressure to the head 41 to cause radial displacement.

[0043] Furthermore, a first groove 12 is provided on the outer side of the handle body 10, which is recessed inward. The first groove 12 is used to accommodate the trigger 30. The trigger 30 is concealed inside the handle body 10, which can minimize the risk of accidentally triggering the trigger 30.

[0044] The elastic body 50 is sleeved on the rod 42 and abuts against the head 41 and the corresponding position of the handle body 10. The elastic body 50 can adopt a wave-shaped washer structure, which can deform when squeezed, thereby changing the distance between the head 41 and the handle body 10, so that the transmission body 40 can be radially displaced.

[0045] The locking body 60 and the elastic body 50 are respectively disposed on opposite sides of the tube body 20. The locking body 60 can move radially with the transmission body 40. The locking body 60 and the locking body 70 are engaged and locked without external force. During the rotation of the trigger 30, the transmission body 40 can drive the transmission body 40 to squeeze the elastic body 50, so that the transmission body 40 drives the locking body 60 to move radially and disengage from the locking body 70, thereby releasing the engagement and locking state.

[0046] Meanwhile, an elongated adjustment hole 21 is provided on the tube body 20 along its axial direction. The adjustment hole 21 passes through the tube body 20 and the second locking body 70. The adjustment hole 21 allows the rod part 42 to pass through, and the rod part 42 can move within the adjustment hole 21. This allows the position of the first locking body 60 on the second locking body 70 to change, thereby enabling the extension and retraction of the tube body 20 and adjusting the height.

[0047] The second locking body 70 is generally U-shaped and fits against the outer wall of the tube 20. A groove is provided on one side of the first locking body 60. The groove matches the shape of the second locking body 70 and can just cover the second locking body 70. The length of the second locking body 70 is greater than the length of the first locking body 60. Several protruding teeth 80 are provided on the mating surfaces of the first locking body 60 and the second locking body 70. The first locking body 60 and the second locking body 70 are engaged through the protruding teeth 80. The toothed engagement structure can provide a good locking effect.

[0048] Meanwhile, the end of the rod 42 extends to the outside of the locking body 60 and is connected to an adjusting knob 90. The adjusting knob 90 is threadedly engaged with the rod 42. When the adjusting knob 90 is driven to rotate by an external force, it can be displaced along the axial direction of the rod 42. The adjusting knob 90 abuts against the locking body 60. The locking body 60 is provided with a limiting body 61 on the side facing the adjusting knob 90. The adjusting knob 90 is provided with a limiting body 91 on the side facing the locking body 60. The limiting body 91 is located between the limiting body 61 and the locking body 60 and cannot be disengaged from the limiting body 61. The limiting body 91 can rotate within the limiting body 61.

[0049] That is, the adjusting knob 90 and the locking body 60 are not disengaged. By rotating the adjusting knob 90, the engagement tightness between the locking body 60 and the locking body 70 can be adjusted by changing its position on the rod 42.

[0050] A receiving groove 11 is provided inside the handle body 10 to accommodate a locking body 60. The locking body 60 is located within the receiving groove 11 and can move radially along the tube body 20. Correspondingly, a groove is also provided outside the handle body 10 to accommodate an adjusting knob 90. This groove is connected to the receiving groove 11, but the locking body 60 cannot completely extend into this groove, and the adjusting knob 90 cannot completely enter the receiving groove 11.

[0051] When using this invention, pressing the trigger 30 pushes the transmission body 40 to compress the elastic body 50, causing the transmission body 40 to generate radial displacement until it drives the locking body 60 to disengage from the locking body 70. At this time, it is in a telescopic adjustable state. After adjusting to the required height, releasing the trigger 30 causes the elastic body 50 to rebound, causing the locking body 60 to retract to the locking body 70 to achieve engagement and locking.

[0052] Example 2

[0053] like Figures 6-7As shown, the main difference from Embodiment 1 is that the structure and connection relationship of the trigger 30, the transmission body 40, and the elastic body 50 have been changed. Specifically, the trigger 30 is also rotatably connected to the handle body 10. The trigger 30 is a screw-shaped structure rotatably connected to the transmission body 40. One end of the trigger 30 is provided with a cam structure. The cam structure cooperates with the transmission body 40 to apply a force that causes it to move radially. That is, the two form an eccentric cam clamp structure. By rotating the trigger 30, the contact position between the cam structure inside and the transmission body 40 changes. The characteristics of the cam structure cause the transmission body 40 to move, thereby realizing radial movement.

[0054] Here, the locking body 60 is movably sleeved on the transmission body 40. The end of the transmission body 40 away from the trigger 30 is connected to a limiting block for limiting the position of the locking body 60. The limiting block can be directly integrated with the adjustment knob 90 into a single structure, and the limiting block is threadedly connected to the transmission body 40. Thus, the position of the locking body 60 can be finely adjusted by rotating the adjustment knob 90.

[0055] Furthermore, the two elastic bodies 50 are disposed between the inner sides of the locking body 60 and the handle body 10, and the two elastic bodies 50 are respectively located on opposite sides of the tube 20. Two ears 601 are provided on both sides of the locking body 60, and the ears 601 have space to accommodate the elastic bodies 50. Correspondingly, a groove needs to be opened on the inner side of the handle body 10, and the groove corresponds to the position of the ears 601, thereby accommodating and limiting the elastic bodies 50. The elastic bodies 50 can be spring structures.

[0056] Here, the locking body 60 can be engaged with the limiting block in the adjusting knob 90 by directly contacting its end face, or the engaging structure of the limiting body 61 and the limiting body 91 in Embodiment 1 can be adopted.

[0057] When in use, the trigger 30 is rotated, which pushes the transmission body 40, causing the adjustment knob 90 to produce radial displacement. The elastic body 50 thereby causes the locking body 60 to disengage from the locking body 70, at which point it is in an adjustable state. After adjusting to the required height, the trigger 30 is rotated back, and the locking body 60 retracts to the locking body 70 under the action of the adjustment knob 90 to achieve engagement and locking.

[0058] In addition, this embodiment also provides a tool including the above-mentioned telescopic handle structure, such as a snowplow, which can be used to adjust the height of use to suit users of different heights.

[0059] The examples, embodiments, and particular forms of the invention illustrated have been shown and described in detail in the accompanying drawings and foregoing description, and should also be considered illustrative rather than restrictive. The description of a particular feature in one embodiment does not imply that those particular features must be limited to that one embodiment. Features of one embodiment can be used in combination with features of other embodiments, as will be understood by those skilled in the art, whether or not explicitly stated. Exemplary embodiments have been shown and described, and all variations and modifications fall within the spirit of the invention and are intended to be protected.
