Description

Technical Field

[0001] This utility model relates to the field of linkage technology, specifically a new type of high-strength anti-slip linkage. Background Technology

[0002] Telescopic poles are functional rods whose length can be changed by sliding, folding or rotating. They are widely used in industrial equipment, furniture, sports equipment and other fields. Their core lies in structural design and locking mechanism.

[0003] A search revealed that the announcement number is CN117006216A, and the name is "A Gear and Rack Linkage Telescopic Rod," which includes a telescopic component, an isolation cover, and a power component. Through research and analysis, it was found that although the device achieves linkage lifting of the rod from bottom to top and from outside to inside, with good axial and torsional accuracy and excellent performance, it still has the following shortcomings to some extent.

[0004] For example, the overall structure is a linkage mechanism, which does not allow for independent adjustment of each section of the telescopic rod. When extending, each telescopic component must be pulled out one by one before it can be used. Furthermore, the locking structure of the device is relatively complex, making it difficult for users to lock. It is also inconvenient to carry and use when going out. In order to solve the above technical problems, we have designed a new type of high-strength anti-slip linkage rod. Utility Model Content

[0005] The purpose of this invention is to provide a novel high-strength anti-slip linkage rod, which is adjustable, easy to lock, and portable. It solves the problems of having to pull out each telescopic component individually for use, having a complex locking structure, and being inconvenient for carrying around.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel high-strength anti-slip linkage rod, comprising a housing, an anti-slip protective sleeve fixedly sleeved on the left side of the housing surface, an extension shell one disposed in the inner cavity of the housing, an extension shell two disposed in the inner cavity of the extension shell one, an extension shell three disposed in the inner cavity of the extension shell two, and an extension shell four disposed in the inner cavity of the extension shell three. A clamping assembly is sleeved and installed on the right end of the surfaces of the housing, extension shell one, extension shell two, and extension shell three. The clamping assembly includes an mounting sleeve, a clamping handle movably mounted on the right side of the top of the mounting sleeve, a clamping plate disposed on the right side of the top of the mounting sleeve, and slots formed on the tops of extension shell one, extension shell two, extension shell three, and extension shell four. A lifting assembly is disposed on the left side of the housing.

[0007] Preferably, the anti-slip sleeve is made of rubber, and the surface of the anti-slip sleeve has several anti-slip grooves.

[0008] Preferably, the mounting sleeves are fixedly fitted onto the right ends of the surfaces of the outer shell, extension shell one, extension shell two, and extension shell three, respectively, and the clamping handle is rotatably connected to the right side of the top of the mounting sleeve via a rotating shaft.

[0009] Preferably, an installation groove is provided on the right side of the top of the mounting sleeve, and the clamping plate is fixedly installed on the left side of the inner cavity of the installation groove.

[0010] Preferably, the slot is engaged with the clamping plate on its top, and the bottom of the clamping handle has a raised structure and contacts the top of the clamping plate.

[0011] Preferably, the lifting assembly includes a receiving cavity, which is opened on the left side of the outer shell, and a lifting rope is fixedly connected to the right side inside the receiving cavity.

[0012] Preferably, a connecting strip is fixedly connected to the left side of the bottom of the outer shell, and a cover plate is fixedly connected to the bottom of the connecting strip, the cover plate being matched with the size of the receiving cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model sets up multiple telescopic components, each of which is clamped and fixed by a clamping assembly. When telescopic movement is required, simply unfold the clamping handle to move the clamping plate out of the slot, and the telescopic component can be stretched at will. Simply turn the clamping handle again to press the clamping plate into the slot and lock it in place. The overall operation is very fast and the locking is convenient, which improves the efficiency of telescopic adjustment.

[0015] 2. This utility model hides the lifting rope inside the receiving cavity. When needed, simply open the cover to remove the lifting rope for hand carrying. The overall structure is simple and easy to operate, and it can be hidden when not in use, improving the convenience of external carrying. Attached Figure Description

Detailed Implementation

[0022] Please see Figures 1-5 A novel high-strength anti-slip linkage rod includes an outer shell 1. An anti-slip protective sleeve 2 is fixedly sleeved on the left side of the surface of the outer shell 1. An extension shell 4 is provided in the inner cavity of the outer shell 1. An extension shell 5 is provided in the inner cavity of the extension shell 4. An extension shell 6 is provided in the inner cavity of the extension shell 25. An extension shell 7 is provided in the inner cavity of the extension shell 36. A clamping assembly 3 is sleeved and installed on the right end of the surface of the outer shell 1, the extension shell 4, the extension shell 25 and the extension shell 36. The clamping assembly 3 includes an installation sleeve 31. A clamping handle 32 is movably installed on the right side of the top of the installation sleeve 31. A clamping plate 33 is provided on the right side of the top of the installation sleeve 31. A slot 8 is opened on the top of the extension shell 4, the extension shell 25, the extension shell 36 and the extension shell 47. A lifting assembly 9 is provided on the left side of the outer shell 1.

[0023] The anti-slip sleeve 2 is made of rubber. By setting the anti-slip sleeve 2, it is easier for users to hold the outer shell 1 and use it, and the friction of hand grip is improved. The surface of the anti-slip sleeve 2 is provided with several anti-slip grooves. By setting the anti-slip grooves, the comfort of hand gripping the anti-slip sleeve 2 can be further improved.

[0024] Mounting sleeves 31 are respectively fixedly mounted on the right end of the surfaces of outer shell 1, extension shell 4, extension shell 5, and extension shell 6. The right end of each mounting sleeve 31 is flush with the right end of the surfaces of outer shell 1, extension shell 4, extension shell 5, and extension shell 6. The clamping handle 32 is rotatably connected to the right side of the top of the mounting sleeve 31 via a pivot. The pivot connection allows the clamping handle 32 to rotate easily, enabling it to lock and unlock quickly. Outer shell 1, extension shell 4, extension shell 5, extension shell 6, and extension shell 7 are all made of aluminum alloy, which has the advantages of being lightweight and high-strength, greatly reducing weight during use, and also has the advantages of corrosion resistance and low-temperature resistance.

[0025] The mounting sleeve 31 has a mounting groove 34 on the right side of its top. The clamping plate 33 is fixedly installed on the left side of the inner cavity of the mounting groove 34. By setting the mounting groove 34, the front and rear sides of the clamping plate 33 can be unrestrained, which makes it convenient for the clamping handle 32 to press against the clamping plate 33 to deform. The mounting sleeve 31, the clamping handle 32 and the clamping plate 33 are all made of plastic, which has the advantages of low cost and easy processing, and enables the clamping plate 33 to deform after being squeezed.

[0026] The slot 8 is engaged with the clamping plate 33 on its top. The bottom of the clamping handle 32 has a raised structure and contacts the top of the clamping plate 33. The raised structure allows the clamping handle 32 to press against the clamping plate 33, so that the clamping plate 33 loses pressure in the unfolded state and returns to the normal state, thereby moving out of the slot 8 and achieving contact locking.

[0027] The lifting assembly 9 includes a receiving cavity 91, which is located on the left side of the outer shell 1. A lifting rope 92 is fixedly connected to the right side inside the receiving cavity 91. The lifting rope 92 makes it convenient for users to carry the device by hand.

[0028] A connecting strip 93 is fixedly connected to the left side of the bottom of the outer casing 1. A cover plate 94 is fixedly connected to the bottom of the connecting strip 93. The cover plate 94 matches the size of the receiving cavity 91. By setting the connecting strip 93, the cover plate 94 can be connected to the outer casing 1 to prevent the cover plate 94 from being lost. By setting the cover plate 94, the receiving cavity 91 can be closed, so that the lifting rope 92 is hidden inside the receiving cavity 91.

[0029] In use, hold the anti-slip sleeve 2 of the outer shell 1. When extension is required, pull the locking handle 32 out to the specified length, then press the locking handle 32 to rotate it counterclockwise until it is close to the top of the mounting sleeve 31. At this time, the protruding structure at the bottom of the locking handle 32 presses the locking plate 33 during the rotation, causing it to deform. This causes the right end of the locking plate 33 to move downward and lock into the slot 8 at its bottom, thus locking it. Following the above method, the extension shell 1 4, extension shell 2 5, extension shell 3 6 and extension shell 4 7 can be pulled out one by one. The extension shell 4 7 has a hollow structure inside, and tools can be inserted inside for use. The entire device can be carried by hand using the lifting rope 92. In use, the lifting rope 92 can be placed inside the receiving cavity 91, and then the cover plate 94 can be placed inside the receiving cavity 91 to hide the lifting rope 92.

[0030] In summary, this new high-strength anti-slip linkage rod, through the cooperation of the outer shell 1, anti-slip sleeve 2, locking component 3, extension shell one 4, extension shell two 5, extension shell three 6, extension shell four 7, slot 8 and lifting component 9, solves the problem that each telescopic component must be pulled out one by one before it can be used, and that the locking structure of the device is relatively complicated and inconvenient to carry when going out.
