Description

Technical Field

[0001] The utility model relates to the field of daily necessities, in particular to a high-stability telescopic rod. Background Art

[0002] Telescopic rods are an important accessory for household cleaning tools, and their length can be adjusted according to the needs of users. Usually, a telescopic rod is composed of at least two rods, which are plugged into each other. There are expansion joints and locking rings at the ends of the rods. The locking and movement between the rods are achieved by rotating the locking ring to control the size of the expansion joint. The problem with this type of telescopic rod is that in order to facilitate the plug-in movement of the rods, there are usually gaps between the rods. The rods are only clamped at the ends, which makes them easy to shake, and axial movement between the rods is easy to occur when the clamping force is insufficient. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a telescopic rod with high stability.

[0004] The high-stability telescopic rod comprises at least two sections of rods, which are plugged into each other. The rod is provided with an insertion end and an inserted end. A plug is provided in the port of the insertion end. The plug protrudes from the port of the insertion end, and the outer diameter of the protruding end of the plug matches the inner diameter of the inserted end. Such a design fills the gaps between the rods and prevents the rods from shaking.

[0005] Furthermore, a locking mechanism is provided, which includes an annular intermediate sleeve, and a first clamp and a second clamp integrally formed at the front and rear ends of the intermediate sleeve, wherein the inner diameters of the first clamp and the intermediate sleeve are the same, and the inner diameters of the two match the outer diameters of the inserted end, and the locking mechanism can be fastened to the inserted end of one section of the rod through the first clamp, and the inner diameter of the second clamp matches the outer diameter of the insertion end of another section of the rod through the second clamp. Since the intermediate sleeve and the second clamp have different inner diameters, a limiting step is formed at the combined position of the two, and the limiting step can be pressed against the port of the inserted end to prevent axial movement between the rods.

[0006] Furthermore, the two butt joints of the first clamp are connected by screws, and the distance between the two butt joints can be controlled by the screws, thereby controlling the locking force of the first clamp.

[0007] Furthermore, a rotary switch is provided between the two butt joints of the second clamp, and the rotary switch is provided with two end heads, which are pivotally connected to the outer side surfaces of the two butt joints of the second clamp, and obliquely arranged wedge-shaped grooves are provided on the joint surfaces of the end heads and the butt joints. Through the wedge groove, the rotational force of the rotary switch can be converted into axial force to control the distance of the two butt joints of the second clamp, so that the locking force of the second clamp can be quickly controlled to change. This design makes the locking control of the insertion end cooperating with the second clamp more convenient, makes the adjustment of the insertion depth of the insertion end more convenient, and makes the overall length adjustment more convenient.

[0008] Furthermore, a handle is provided on the rod at the end to increase friction.

[0009] Furthermore, the handle includes a first handle at the end of the rod and a second handle at the middle of the rod. This design is designed to meet the needs of two-handed holding in longer usage scenarios. At the same time, to meet the need for a wider contact area between the end grip and the hand, the first handle is provided with a circle of concave and convex grooves arranged along its circumference.

[0010] Furthermore, in view of the requirement that the other hand holds the middle part of the rod mainly to control the direction of the telescopic rod, the second handle is provided with a concave-convex groove arranged along the axial direction only in a certain direction.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model provides a high-stability telescopic rod, which can prevent the rod from shaking through the design of the plug, and can prevent the axial movement between the rods through the design of the locking structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is now further described with reference to the accompanying drawings.

[0020] like Figure 1-Figure 5 As shown, a high-stability telescopic rod with five sections of rods 1 is shown, and its application scenario is mainly cleaning at high places, such as roofs. A broom or a nozzle can be installed on the uppermost rod 1 for sweeping or washing.

[0021] Specifically, the rods 1 are plugged into each other, and accordingly, the rod 1 has an insertion end 2 and an inserted end 3, and a plug 4 is provided in the port of the insertion end 2. The plug 4 protrudes from the port of the insertion end 2, and the outer diameter of the protruding end of the plug 4 matches the inner diameter of the inserted end 3. In this way, when the two sections of the rod 1 are plugged into each other, the gap between the rods 1 is filled with the plug 4, which can prevent the rod 1 from shaking.

[0022] Preferably, the high-stability telescopic rod is provided with a locking mechanism 5, which includes an annular intermediate sleeve 501, and a first clamp 502 and a second clamp 503 integrally formed at the front and rear ends of the intermediate sleeve 501, wherein the first clamp 502 and the intermediate sleeve 501 have the same inner diameter, and the inner diameters of the two match the outer diameter of the inserted end 3, and the locking mechanism 5 can be fastened to the inserted end 3 of one section of the rod member 1 through the first clamp 502, and the inner diameter of the second clamp 503 matches the outer diameter of the insertion end 2 of another section of the rod member 1, and the locking mechanism 5 can be fastened to the insertion end 2 of the other section of the rod member 1 through the second clamp 503, and because the intermediate sleeve 501 and the second clamp 503 have different inner diameters, the combination position of the two forms a limiting step 504, and the limiting step 504 can be pressed against the port of the inserted end 3.

[0023] Preferably, the two butt joints of the first clamp 502 are connected by screws.

[0024] Preferably, a rotary switch 6 is provided between the two butt joints of the second clamp 503. The rotary switch 6 is provided with two ends, which are pivotally connected to the outer side surfaces of the two butt joints of the second clamp 503. The joint surfaces of the ends and the butt joints are provided with obliquely arranged wedge-shaped grooves 7. Through the wedge-shaped grooves 7, the rotational force of the rotary switch 6 can be converted into an axial force to control the distance between the two butt joints of the second clamp 503, so that the locking force of the second clamp 503 can be quickly controlled to change. It should be noted that the maximum tightness of the rotary switch 6 is limited by the rotation angle of the rotary switch 6. Specifically, rotating to the bottom in one direction means that the second clamp 503 is loosened to the maximum, and rotating to the bottom in the other direction means that the second clamp 503 is locked to the tightest. On this basis, the maximum looseness can also be controlled by adding screws to prevent the high-stability telescopic rod from accidentally sliding uncontrollably due to excessive looseness after it is loosened. Specifically, the second clamp 503 is provided with two ends of a screw inserted through the rotary switch 6 and two docking ends of the second clamp 503, and the end of the screw is locked with a nut. A knob 8 is screwed on the screw in the direction opposite to the nut. By controlling the knob 8, one docking end of the second clamp 503 can be pressed to move toward the other docking end, thereby controlling the maximum looseness of the second clamp 503.

[0025] Preferably, a handle is provided on the rod 1 at the end. The handle includes a first handle 9 at the end of the rod 1 and a second handle 10 at the middle of the rod 1. The first handle 9 is provided with a circle of concave-convex grooves arranged along its circumference, and the second handle 10 is provided with concave-convex grooves arranged along the axial direction only in a certain direction.
