Description

Technical Field

[0001] The present application relates to the field of cleaning tools, and particularly to a telescopic grip for a cleaning tool. Background Art

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

[0003] In the field of cleaning, grips are provided on cleaning tools such as mops, brooms, window wipers, and window scrapers. By grasping the grip, it is convenient to drive the cleaning tool. The cleaning tool needs to adjust the length of the grip according to the user's height and the usage environment. Existing cleaning tools usually divide the grip into a fixed rod and a sliding rod, and a fixing member is provided 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 fixed by the fixing member. Adjusting the length of the existing grip requires squatting or lifting the tool to adjust the length, and the process of length adjustment is relatively complicated. Summary of the Invention

[0004] In order to facilitate the length adjustment of the grip, the present application provides a telescopic grip for a cleaning tool.

[0005] The telescopic grip for a cleaning tool provided by the present application adopts the following technical solutions: A telescopic grip for a cleaning tool includes a fixed rod and a sliding rod. The sliding rod is sleeved outside 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 one end of the sliding rod away from the fixed rod.

[0006] By adopting the above technical solution, the locking mechanism is driven by pressing the button, so that the locking between the fixed rod and the sliding rod is released. At this time, the sliding rod and the fixed rod can be driven to slide relative to each other, so as to adjust the overall length of the grip, and there is no need to squat or lift the tool to adjust the length, which facilitates the length adjustment of the grip.

[0007] Optionally, the locking mechanism includes a locking member. The locking member is slidably arranged on the sliding rod, the locking member abuts against the fixed rod, and the button is slidably arranged on the sliding rod. The button slides towards the fixed rod to drive the locking member away from the fixed rod.

[0008] By adopting the above technical solution, the locking member is driven away from the fixed rod by pressing the button, so that the locking between the fixed rod and the sliding rod is released. At this time, the sliding rod and the fixed rod can be driven to slide relative to each other, so as to adjust the overall length of the grip, and there is no need to squat or lift the tool to adjust the length, which facilitates the length adjustment of the grip.

[0009] Optionally, the fixed rod includes a positioning sleeve and a tube. The tube is sleeved and fixed outside the positioning sleeve. The sliding rod includes an outer sleeve and an inner sliding bracket. The outer sleeve is sleeved and fixed outside the inner sliding bracket. The outer sleeve is sleeved outside the tube, and the inner sliding bracket is slidably arranged inside the positioning sleeve. The locking member is slidably arranged on the inner sliding bracket and abuts against the inner wall of the positioning sleeve.

[0010] By adopting the above technical solution, the sliding can be guided through the setting of the positioning sleeve and the inner sliding bracket, making the sliding between the fixed rod and the sliding rod smoother.

[0011] Optionally, a plurality of jacks are uniformly arranged on the positioning sleeve along the length direction of the positioning sleeve. An insertion block is fixed on the locking member, and the insertion block is inserted into any one of the jacks.

[0012] By adopting the above technical solution, the cooperation of the jack and the insertion block can further improve the locking effect.

[0013] Optionally, the locking mechanism further includes a driving rod, a wedge block and an elastic member. The driving rod is slidably inserted into the inner sliding bracket. One end of the driving rod is fixed to the button. The wedge block is fixed to the end of the driving rod away from the button. A driving groove is formed on the locking member. The wedge block is inserted into the driving groove. The wedge surface of the wedge block abuts against the locking member. The elastic member is installed between the inner sliding bracket and the locking member. The elastic member drives the locking member to abut against the positioning sleeve through elasticity.

[0014] By adopting the above technical solution, when pressure is applied to the button, the wedge block is driven by the driving rod to drive the locking member to disengage from the positioning sleeve. When the pressure on the button is removed, the locking member is reset under the elastic force of the elastic member and abuts against the positioning sleeve again.

[0015] Optionally, a biasing spring is arranged between the button and the outer sleeve.

[0016] By adopting the above technical solution, the setting of the biasing spring can, on the one hand, facilitate the reset of the button after the force for pressing the button is removed, and at the same time, it can also increase the force required to press the button, reducing the probability of the button being accidentally pressed due to the gravity of the button or other external forces.

[0017] Optionally, an anti-disengagement groove is formed on the inner sliding bracket. An anti-disengagement block is fixed on the driving rod. When the driving rod slides away from the fixed rod, the anti-disengagement block is clamped in the anti-disengagement groove.

[0018] By adopting the above technical solution, the cooperation of the anti-disengagement groove and the anti-disengagement block can reduce the probability of the button disengaging from the sliding rod due to excessive elastic force when the button rebounds.

[0019] Optionally, a chamfer is formed on the side of the anti-disengagement block facing the fixed rod.

[0020] By adopting the above technical solution, the formation of the chamfer can reduce the resistance of the anti-disengagement block to the sliding of the driving rod in the direction towards the fixed rod.

[0021] Optionally, a plurality of weight-reducing grooves are formed in the outer side wall of the positioning sleeve.

[0022] By adopting the above technical solution, the formation of the weight-reducing grooves can reduce the overall weight of the grip and also facilitate reducing the probability that the positioning outer sleeve or the pipe is deformed due to excessive glue thickness when applying glue to the positioning sleeve.

[0023] Optionally, at least one plane is circumferentially formed on the inner sliding bracket.

[0024] By adopting the above technical solution, the grip is usually cylindrical. When the positioning sleeve, the pipe, the outer sleeve and the inner sliding bracket are all cylindrical, the fixing rod and the sliding rod can rotate relative to each other. When the fixing rod and the sliding rod rotate relative to each other, the locking mechanism will shift, resulting in abnormal locking. By forming the plane, the probability that the fixing rod and the sliding rod rotate relative to each other can be reduced, thereby reducing the probability that the locking mechanism is misaligned. In summary, the present application includes at least one of the following beneficial technical effects: By pressing the button to drive the locking member to disengage from the fixing rod, the locking between the fixing rod and the sliding rod is released. At this time, the sliding rod and the fixing rod can be driven to slide relative to each other, thereby adjusting the overall length of the grip. There is no need to squat down or lift the tool for length adjustment, which is convenient for adjusting the length of the grip. Through the arrangement of the positioning sleeve and the inner sliding bracket, the sliding can be guided, making the sliding between the fixing rod and the sliding rod smoother. When pressure is applied to the button, the wedge block is driven by the driving rod to drive the locking member to disengage from the positioning sleeve. When the pressure on the button is removed, the locking member is reset under the elastic force of the elastic member and abuts against the positioning sleeve again. The arrangement of the biasing spring can, on the one hand, facilitate the reset of the button after the force for pressing the button is removed, and at the same time, can also increase the force required to press the button, reducing the probability that the button is accidentally pressed due to the gravity of the button or other external forces.

[0031] The present application embodiment discloses a telescopic handle for a cleaning tool, referring to Figure 1 and Figure 2 , including 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 relatively, characterized in that: a locking mechanism 3 is arranged between the sliding rod 2 and the fixed rod 1, and a button 13 for unlocking the locking mechanism 3 is arranged at the end of the sliding rod 2 away from the fixed rod 1, and the locking mechanism 3 includes a locking piece 31, and the locking piece 31 is slidably arranged on the sliding rod 2, and the locking piece 31 abuts against the fixed rod 1, and the button 13 is slidably arranged on the sliding rod 2, and the button 13 slides toward the fixed rod 1 to drive the locking piece 31 to disengage from the fixed rod 1, and the locking piece 31 is driven to disengage from the fixed rod 1 by pressing the button 13, so that the locking between the fixed rod 1 and the sliding rod 2 is released. At this time, the sliding rod 2 and the fixed rod 1 can be driven to slide relatively, so as to adjust the overall length of the handle, and there is no need to squat or lift the tool to adjust the length, which is convenient for adjusting the length of the handle.

[0032] Referring to Figure 2 and Figure 3 , the fixed rod 1 includes a positioning sleeve 101 and a tube 102. The tube 102 is sleeved and fixed outside the positioning sleeve 101. A plurality of weight-reducing grooves 11 are formed on the outer side wall of the positioning sleeve 101. The fixing between the tube 102 and the positioning sleeve 101 is realized by filling glue or placing double-sided tape in the weight-reducing grooves 11. The sliding rod 2 includes an outer sleeve 21 and an inner sliding bracket 22. The outer sleeve 21 is sleeved and fixed outside the inner sliding bracket 22. An annular mounting table 12 is integrally formed on the outer sleeve 21. The inner sliding bracket 22 is fixedly mounted on the mounting table 12 by glue. The arrangement of the mounting table 12 makes the outer sleeve 21 and the inner sliding bracket 22 concentric and arranged with a gap. Thus, when the outer sleeve 21 is sleeved outside the tube 102, the inner sliding bracket 22 is slidably inserted into the positioning sleeve 101. The locking member 31 is slidably arranged on the inner sliding bracket 22 and abuts against the inner wall of the positioning sleeve 101. The arrangement of 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.

[0033] Referring to Figure 2 and Figure 3 , a plurality of insertion holes 4 or grooves are uniformly formed on the positioning sleeve 101 along the length direction of the positioning sleeve 101. In this embodiment, insertion holes 4 are formed on the positioning sleeve 101. An insertion block 5 is fixed on the locking member 31. The insertion block 5 is slid with the inner sliding bracket 22 and inserted into any one of the insertion holes 4. The locking effect is improved by inserting the insertion block 5 into the insertion hole 4. At the same time, the arrangement of the positioning sleeve 101 makes the insertion holes 4 not exposed, thereby reducing the probability that the locking member 31 is separated from the fixed rod 1 due to an external force hitting the insertion block 5. The inner sliding bracket 22 is circumferentially provided with not less than one plane. In this embodiment, the inner sliding bracket 22 is circumferentially provided with four planes, forming a column with a rectangular cross-section. The inner sliding bracket 22 with a circular cross-section will rotate in the positioning sleeve 101, resulting in the misalignment of the insertion block 5 and the insertion hole 4 and unable to be normally inserted into the insertion hole 4. The rectangular inner sliding bracket 22 will not rotate in the positioning sleeve 101, thereby reducing the probability that the insertion block 5 cannot be aligned with the insertion hole 4 due to the rotation of the inner sliding bracket 22.

[0034] Referring to Figure 2 and Figure 3, the locking mechanism 3 further includes a driving rod 32, a wedge block 33 and an elastic member 34. The driving rod 32 is slidably inserted into the inner sliding bracket 22. The driving rod 32 is a rectangular long bar. One end of the driving rod 32 is fixed to the button 13. The wedge block 33 is fixed to the end of the driving rod 32 away from the button 13. A driving groove 6 is formed in the locking member 31. The wedge block 33 is inserted into the driving groove 6. The wedge surface of the wedge block 33 abuts against the locking member 31. The elastic member 34 is installed between the inner sliding bracket 22 and the locking member 31. In this embodiment, the elastic member 34 is a compression spring. The elastic member 34 drives the locking member 31 to abut against the positioning sleeve 101 by elastic force. When the button 13 is pressed, the driving rod 32 is driven to slide towards the locking member 31 to drive the wedge block 33 to abut against the locking member 31, thereby driving the locking member 31 to slide away from the positioning sleeve 101, so that the insertion block 5 disengages from the insertion hole 4. At this time, the locking between the fixed rod 1 and the sliding rod 2 is released, and the fixed 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 elastic member 34 drives the locking member 31 to slide towards the positioning sleeve 101 to abut against the positioning sleeve 101 and insert the insertion block 5 into the insertion hole 4; a force-applying spring 7 is arranged between the button 13 and the outer sleeve 21. The arrangement of the force-applying spring 7 can, on the one hand, facilitate the reset of the button 13 after the force for pressing the button 13 is removed, and at the same time, can also increase the force required to press the button 13 and reduce the probability that the button 13 is accidentally pressed due to the gravity of the button 13 or other external forces. Refer to Figure 2 and Figure 3 , an anti-detachment groove 8 is formed in the inner sliding bracket 22, and an anti-detachment block 9 is fixed on the driving rod 32. When the driving rod 32 slides away from the fixed rod 1, the anti-detachment block 9 is clamped in the anti-detachment groove 8. The cooperation of the anti-detachment groove 8 and the anti-detachment block 9 can reduce the probability that the button 13 detaches from the sliding rod 2 due to excessive elastic force when the button 13 rebounds; a chamfer 10 is formed on the side of the anti-detachment block 9 facing the fixed rod 1. The formation of the chamfer 10 can reduce the resistance of the anti-detachment block 9 to the sliding of the driving rod 32 towards the fixed rod 1.

[0035] The implementation principle of the embodiment of the present application is as follows: Solid glue is filled in the weight-reducing groove 11, and then the positioning sleeve 101 is fixedly installed in the tube 102. At the same time, glue is applied on the inner sliding bracket 22 to fixedly install the inner sliding bracket 22 on the outer sleeve 21. Then, the locking mechanism 3 is installed on the sliding rod 2, and the fixed rod 1 is sleeved on the sliding rod 2 to complete the installation of the grip.
