Description

Technical Field

[0001] This utility model relates to the field of telescopic rod technology, specifically to a telescopic rod quick-locking structure. Background Technology

[0002] Pull-out telescopic poles have a variety of uses. Some telescopic poles do not have a locking function and rely solely on the damping force between the poles, or the locking effect of the built-in locking structure is limited, which can easily cause the poles to slip. In addition, many locking structures are located at the tail end of the pole. If the inner pole is not fully pulled out, the locking structure will not be triggered, causing inconvenience during use.

[0003] Therefore, this solution provides a quick-locking structure for telescopic rods, which can be applied to existing telescopic rods to further lock the connection between two sets of adjacent rods. Utility Model Content

[0004] (I) Technical Issues

[0005] The present invention aims to at least solve the problem of slippage at the connection of telescopic rods in the prior art.

[0006] (II) Technical Content

[0007] This solution provides a quick-locking structure for a telescopic rod, achieved by the following specific technical means: including a main tube, which is placed on the connection between the two rods of the telescopic rod; the rear section of the main tube is fitted onto a set of rods located on the outer layer at the rear, and the front section is fitted onto another set of rods located on the inner layer at the front.

[0008] The front and rear sections of the main tube are locked with corresponding locking structures to secure the front and rear sets of rods respectively.

[0009] Preferred technical solution 1: The locking structure located on the front side of the main body cylinder is a quick-locking mechanism, which realizes quick locking connection or quick separation with the inner layer rod.

[0010] Preferred technical solution 2: The locking structure located at the rear side of the main body is a fixed locking mechanism, which achieves a locking with the outer rod that is not easy to unlock.

[0011] Preferred technical solution 3: The main body cylinder has a C-shaped structure, and the two near ends of the C-shaped structure are bent upward and extended to form two sets of parallel lugs;

[0012] The lugs include two sets of lug 1 located in the rear part of the main body and two sets of lug 2 located in the front part of the main body;

[0013] The locking mechanism is connected between two sets of parallel lugs, and the quick-locking mechanism is connected between two sets of parallel lugs.

[0014] Preferred technical solution four: The quick-locking mechanism includes screws passing through two sets of lugs, a crossbar fixed on the screws, and a locking handle rotatably connected to the crossbar. The locking handle has an eccentric cam structure, and the eccentric cam slides against the wall of one set of lugs.

[0015] Preferred technical solution five: The locking mechanism consists of a stud and a matching nut.

[0016] (III) Technical Effects

[0017] The above structure gives this solution the following advantages:

[0018] 1. By setting the main tube at the connection between the inner and outer rods of the telescopic pole, a locking mechanism is formed between the inner and outer rods, improving the stability and flexibility of the telescopic pole in use;

[0019] 2. By utilizing the different locking requirements of the inner and outer rods, different locking states can be provided through the setting of unlocking and locking mechanisms;

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-3 The telescopic rod quick-locking structure includes a main body tube 1 formed by one-piece injection molding of plastic. The main body tube 1 has a certain toughness to avoid breakage during the locking process. The main body tube 1 is placed on the telescopic rod at the connection between the two rods. The middle and rear section of the main body tube 1 is fitted on a set of rods located on the outer layer at the rear side, and the middle and front section is fitted on another set of rods located on the inner layer at the front side.

[0030] The front and rear sections of the main body tube 1 are locked with corresponding locking structures to lock the front and rear rods respectively, thereby achieving further locking of the telescopic rod extension and retraction. The locking structure located on the front side of the main body tube 1 is a quick-locking mechanism 2, which realizes quick locking connection or quick separation with the inner rod, thereby avoiding affecting the inner rod's movement in the outer rod.

[0031] The locking structure located at the rear of the main tube 1 is a locking mechanism 3, which achieves a tight lock with the outer rod, making it difficult to unlock and allowing it to be locked on the outer rod for a long time without disassembly.

[0032] Please see Figures 1-3 The telescopic rod quick-locking structure has a C-shaped main tube 1. The two near ends of the C-shaped structure bend upward and extend to form two sets of parallel lugs. The lugs located in the middle and rear of the main tube 1 are separated from the lugs located in the middle and front of the main tube 1. They are called lug 11 and lug 22 respectively. The notch separating lug 11 and lug 22 extends downward to the main tube 1 and separates the middle and upper part of the main tube 1, ensuring that the opening and closing of the middle and front and middle and rear parts of the main tube 1 do not affect each other.

[0033] The locking mechanism 3 is connected between two sets of parallel lugs 11 and is used to control the distance between the two sets of lugs 11, thereby realizing the opening and closing of the C-shaped cavity in the rear part of the main body cylinder 1. When this part of the C-shaped cavity is closed, the locking hoop covers the outer rod.

[0034] The quick-lock mechanism 2 is connected between two sets of parallel lugs 12 and is used to control the distance between the two sets of lugs 12, thereby realizing the opening and closing of the front C-shaped cavity in the main body cylinder 1. When this part of the C-shaped cavity is closed, the locking hoop covers the inner rod.

[0035] Please see Figures 3-5The telescopic rod quick-locking structure includes a screw 21 that slides through the holes in two sets of lugs 12, a cross post 22 fixed to the protruding end of the screw 21, and a locking handle 23 rotatably connected to the cross post 22. An eccentric cam 231 structure is formed around the cross post 22 on the locking handle 23. By rotating the locking handle 23, the side of the eccentric cam 231 can be controlled to slide against the outer wall of a set of lugs 12. When the side of the eccentric cam 231 away from the cross post 22 contacts the outer wall of the set of lugs 12, the eccentric cam 231 squeezes the two sets of lugs 12 closer to each other, thereby causing the C-shaped cavity at the front of the main body cylinder 1 to tend to close.

[0036] Meanwhile, a spring 24 is connected between the two sets of lugs 12. When the side of the eccentric cam 231 away from the horizontal column 22 moves away from the lugs 12 by the rebound of the spring 24, the two sets of lugs 12 can be pushed away and reset by the rebound force.

[0037] As a preferred embodiment, the crossbar 22 has a threaded hole 221, which is used to assemble and connect with the screw 21.

[0038] Please see Figure 1 and Figure 3 The telescopic rod quick-locking structure is composed of a stud 31 and a matching nut 32. The stud 31 slides through the holes on the two sets of lugs 11 and the rear end is tightened by the nut 32, which squeezes the two sets of lugs 11 closer to each other, so that the C-shaped cavity in the middle and rear of the main body cylinder 1 is closed and locked on the outer rod.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
