Description

Technical Field

[0001] This application relates to the field of cleaning tools, and more particularly to a retractable handle for a cleaning tool. Background Technology

[0002] A grip is the part of an object that a person holds, typically designed to enhance control, comfort, and stability. It has wide applications in many fields.

[0003] In the cleaning industry, cleaning tools such as mops, brooms, squeegees, and window scrapers are all equipped with handles. These handles allow for easy gripping and operation. The handle length of cleaning tools needs to be adjusted according to the user's height and the environment in which they are used. Existing cleaning tools typically divide the handle into a fixed rod and a sliding rod, with a fixing device at the connection between the fixed rod and the sliding rod. The length is adjusted by sliding the sliding rod on the fixed rod and then fixed by the fixing device. Adjusting the length of existing handles requires squatting or lifting the tool, which is a relatively complicated process. Utility Model Content

[0004] To facilitate handle length adjustment, this application provides a telescopic handle for a cleaning tool.

[0005] The technical solution for the telescopic handle of a cleaning tool provided in this application is as follows:

[0006] A telescopic handle for a cleaning tool includes a fixed rod and a sliding rod. The sliding rod is sleeved over the fixed rod, and the sliding rod and the fixed rod slide relative to each other. A locking mechanism is provided between the sliding rod and the fixed rod, and a button for unlocking the locking mechanism is provided at the end of the sliding rod away from the fixed rod.

[0007] By adopting the above technical solution, the locking mechanism is driven by pressing the button, thereby releasing the lock between the fixed rod and the sliding rod. At this time, the sliding rod and the fixed rod can be driven to slide relative to each other, thereby adjusting the overall length of the handle. There is no need to squat or lift the tool to adjust the length, making it convenient to adjust the length of the handle.

[0008] Optionally, the locking mechanism includes a locking member slidably disposed on a sliding rod, the locking member abutting against a fixed rod, and a button slidably disposed on the sliding rod, the button sliding toward the fixed rod driving the locking member to disengage from the fixed rod.

[0009] By adopting the above technical solution, pressing the button drives the locking component to disengage from the fixed rod, thereby releasing the lock between the fixed rod and the sliding rod. At this time, the sliding rod and the fixed rod can be driven to slide relative to each other, thereby adjusting the overall length of the handle. This eliminates the need to squat or lift the tool to adjust the length, making it convenient to adjust the length of the handle.

[0010] Optionally, the fixing rod includes a positioning sleeve and a tube, the tube being sleeved and fixed outside the positioning sleeve, the sliding rod includes an outer sleeve and an inner sliding bracket, the outer sleeve being sleeved and fixed outside the inner sliding bracket, the outer sleeve being sleeved outside the tube, the inner sliding bracket being slidably disposed inside the positioning sleeve, and the locking member being slidably disposed on the inner sliding bracket and abutting against the inner wall of the positioning sleeve.

[0011] By adopting the above technical solution, the positioning sleeve and inner sliding bracket can guide the sliding, making the sliding between the fixed rod and the sliding rod smoother.

[0012] Optionally, the positioning sleeve is provided with a plurality of insertion holes evenly distributed along the length of the positioning sleeve, and the locking member is fixed with an insertion block, which is inserted into any of the insertion holes.

[0013] By adopting the above technical solution, the locking effect can be further improved by combining the socket with the plug.

[0014] Optionally, the locking mechanism further includes a drive rod, a wedge block, and a spring element. The drive rod is slidably inserted into the inner sliding bracket, and one end of the drive rod is fixed to the button. The wedge block is fixed to the end of the drive rod away from the button. The locking element has a drive groove, and the wedge block is inserted into the drive groove. The wedge-shaped surface of the wedge block abuts against the locking element. The spring element is installed between the inner sliding bracket and the locking element, and the spring element drives the locking element to abut against the positioning sleeve through elastic force.

[0015] By adopting the above technical solution, when the button is pressured, the wedge block is driven by the drive rod to disengage the locking component from the positioning sleeve. When the pressure on the button is removed, the locking component is reset and re-aggregates against the positioning sleeve under the elastic force of the elastic component.

[0016] Optionally, a force-applying spring is provided between the button and the outer casing.

[0017] By adopting the above technical solution, the setting of the force spring can facilitate the button reset after the force of pressing the button is removed, and at the same time, it can increase the force required to press the button and reduce the probability of the button being accidentally pressed due to the button's weight or other external forces.

[0018] Optionally, the inner sliding bracket is provided with an anti-detachment groove, and the drive rod is fixed with an anti-detachment block. When the drive rod slides away from the fixed rod, the anti-detachment block is engaged in the anti-detachment groove.

[0019] By adopting the above technical solution, the anti-disengagement groove combined with the anti-disengagement block can reduce the probability that the button will detach from the sliding rod due to excessive elasticity when it rebounds.

[0020] Optionally, the anti-detachment block has a chamfer on the side facing the fixing rod.

[0021] By adopting the above technical solution, the chamfer can reduce the resistance of the anti-detachment block to the sliding of the drive rod toward the fixed rod.

[0022] Optionally, a plurality of weight-reducing grooves are provided on the outer wall of the positioning sleeve.

[0023] By adopting the above technical solution, the opening of the weight-reducing groove can reduce the overall weight of the grip and also facilitate the application of adhesive on the positioning sleeve, reducing the probability of the positioning sleeve or tube deforming under stress due to excessive adhesive thickness.

[0024] Optionally, the inner sliding support may have at least one plane circumferentially opened.

[0025] By adopting the above technical solution, the grip is typically cylindrical. When the positioning sleeve, tube, outer sleeve, and inner sliding bracket are all cylindrical, the fixed rod and sliding rod can rotate relative to each other. When the fixed rod and sliding rod rotate relative to each other, the locking mechanism will shift, causing it to fail to lock properly. By creating a flat surface, the probability of the fixed rod and sliding rod rotating relative to each other can be reduced, thereby reducing the probability of misalignment of the locking mechanism.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] By pressing the button, the locking mechanism is disengaged from the fixed rod, thereby releasing the lock between the fixed rod and the sliding rod. At this time, the sliding rod and the fixed rod can be driven to slide relative to each other, thereby adjusting the overall length of the handle. This eliminates the need to squat or lift the tool to adjust the length, making it convenient to adjust the length of the handle.

[0028] The positioning sleeve and inner sliding bracket can guide the sliding, making the sliding between the fixed rod and the sliding rod smoother;

[0029] When pressure is applied to the button, the wedge block is driven by the drive rod to disengage the locking component from the positioning sleeve. When the pressure on the button is removed, the locking component is reset and re-aggregates against the positioning sleeve under the elastic force of the spring component.

[0030] The force spring design facilitates button reset after the force is removed, while also increasing the force required to press the button, thus reducing the probability of accidental button press due to button weight or other external forces. Attached Figure Description

Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] This application discloses a telescopic handle for a cleaning tool, as shown in the embodiments below. Figure 1 and Figure 2 The tool includes a fixed rod 1 and a sliding rod 2. The sliding rod 2 is sleeved outside the fixed rod 1, and the sliding rod 2 and the fixed rod 1 slide relative to each other. The tool is characterized by a locking mechanism 3 between the sliding rod 2 and the fixed rod 1. A button 13 for unlocking the locking mechanism 3 is provided at the end of the sliding rod 2 facing away from the fixed rod 1. The locking mechanism 3 includes a locking element 31, which is slidably disposed on the sliding rod 2 and abuts against the fixed rod 1. The button 13 is slidably disposed on the sliding rod 2. Sliding the button 13 toward the fixed rod 1 drives the locking element 31 to disengage from the fixed rod 1. Pressing the button 13 drives the locking element 31 to disengage from the fixed rod 1, thereby releasing the lock between the fixed rod 1 and the sliding rod 2. At this point, the sliding rod 2 and the fixed rod 1 can be driven to slide relative to each other, thus adjusting the overall length of the grip without needing to squat or lift the tool for length adjustment, making grip length adjustment convenient.

[0038] Reference Figure 2 and Figure 3 The fixing rod 1 includes a positioning sleeve 101 and a tube 102. The tube 102 is fitted and fixed outside the positioning sleeve 101. Several weight-reducing grooves 11 are formed on the outer wall of the positioning sleeve 101. The tube 102 and the positioning sleeve 101 are fixed by filling the weight-reducing grooves 11 with adhesive or placing double-sided tape. The sliding rod 2 includes an outer sleeve 21 and an inner sliding bracket 22. The outer sleeve 21 is fitted and fixed outside the inner sliding bracket 22. An annular mounting platform 12 is integrally formed on the outer sleeve 21. 2. The outer sleeve 21 and the inner sliding bracket 22 are fixed on the mounting platform 12 by adhesive. The mounting platform 12 is set so that the outer sleeve 21 and the inner sliding bracket 22 are concentric and spaced apart. When the outer sleeve 21 is fitted over the tube 102, the inner sliding bracket 22 slides into the positioning sleeve 101. The locking member 31 slides on the inner sliding bracket 22 and abuts against the inner wall of the positioning sleeve 101. The positioning sleeve 101 and the inner sliding bracket 22 can guide the sliding, making the sliding between the fixed rod 1 and the sliding rod 2 smoother.

[0039] Reference Figure 2 and Figure 3 The positioning sleeve 101 has a plurality of insertion holes 4 or grooves evenly provided along its length. In this embodiment, the positioning sleeve 101 has insertion holes 4 and the locking member 31 has a plug 5 fixed thereon. The plug 5 slides into any insertion hole 4 as the inner sliding bracket 22 slides. The insertion of the plug 5 into the insertion hole 4 improves the locking effect. At the same time, the positioning sleeve 101 prevents the insertion hole 4 from being exposed, thereby reducing the probability that the locking member 31 will disengage from the fixing rod 1 due to the impact of external force on the plug 5. The inner sliding bracket 22 has at least one plane in its circumference. In this embodiment, the inner sliding bracket 22 has four planes in its circumference, forming a column with a rectangular cross-section. The inner sliding bracket 22 with a circular cross-section will rotate within the positioning sleeve 101, thereby causing the plug 5 and the insertion hole 4 to be misaligned and unable to be properly inserted into the insertion hole 4. The rectangular inner sliding bracket 22 will not rotate within the positioning sleeve 101, thereby reducing the probability that the plug 5 will not be aligned with the insertion hole 4 due to the rotation of the inner sliding bracket 22.

[0040] Reference Figure 2 and Figure 3The locking mechanism 3 also includes a drive rod 32, a wedge block 33, and a spring element 34. The drive rod 32 is slidably inserted into the inner sliding bracket 22. The drive rod 32 is a rectangular long rod, and one end of the drive rod 32 is fixed to the button 13. The wedge block 33 is fixed to the end of the drive rod 32 away from the button 13. The locking element 31 has a drive groove 6, and the wedge block 33 is inserted into the drive groove 6. The wedge-shaped surface of the wedge block 33 abuts against the locking element 31. The spring element 34 is installed between the inner sliding bracket 22 and the locking element 31. In this embodiment, the spring element 34 is a compression spring. The spring element 34 drives the locking element 31 to abut against the positioning sleeve 101 through its elastic force. When the button 13 is pressed, the drive rod 32 is driven to slide towards the locking element 31, driving the wedge block 33 to abut against the locking element. 31, thereby driving the locking member 31 to slide away from the positioning sleeve 101, causing the insert 5 to disengage from the insertion hole 4. At this time, the lock between the fixing rod 1 and the sliding rod 2 is released, and the fixing rod 1 and the sliding rod 2 can slide relative to each other to adjust the length of the grip. When the pressing force on the button 13 is removed, the spring member 34 drives the locking member 31 to slide towards the positioning sleeve 101 through the spring force, abutting against the positioning sleeve 101 and inserting the insert 5 into the insertion hole 4. A force-applying spring 7 is provided between the button 13 and the outer sleeve 21. The force-applying spring 7 can facilitate the button 13 to reset after the force of pressing the button 13 is removed, and can also increase the force required to press the button 13, reducing the probability of the button 13 being accidentally pressed due to the weight of the button 13 or other external forces.

[0041] Reference Figure 2 and Figure 3 The inner sliding bracket 22 is provided with an anti-detachment groove 8, and the drive rod 32 is fixed with an anti-detachment block 9. When the drive rod 32 slides away from the fixed rod 1, the anti-detachment block 9 is engaged in the anti-detachment groove 8. The anti-detachment groove 8 and the anti-detachment block 9 can reduce the probability that the button 13 will detach from the sliding rod 2 due to excessive spring force when it rebounds. The anti-detachment block 9 is provided with a chamfer 10 on the side facing the fixed rod 1. The chamfer 10 can reduce the resistance of the anti-detachment block 9 to the sliding of the drive rod 32 towards the fixed rod 1.

[0042] The implementation principle of this application embodiment is as follows: solid glue is filled into the weight reduction groove 11, and then the positioning sleeve 101 is fixedly installed in the tube 102. At the same time, adhesive is applied to the inner sliding bracket 22 and the inner sliding bracket 22 is fixedly installed on the outer sleeve 21. Then the locking mechanism 3 is installed on the sliding rod 2, and the fixing rod 1 is sleeved on the sliding rod 2 to complete the installation of the grip.

[0043] It should be noted that the above embodiments are only used to illustrate this application and are not intended to limit the technical solutions described in this application. Although this specification has described this application in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to this application. All technical solutions and improvements that do not depart from the spirit and scope of this application should be covered within the scope of the claims of this application.
