[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0044] Example 1

[0045] Reference Figure 1~Figure 5 , which is the first embodiment of the present invention, provides a connecting rod with rotation locking control, including a rod body 100, a rotation mechanism and a double locking mechanism. Double locking is achieved by limiting the engagement of the first claw 300 and the second claw 301 with the first slot 1013 and the second slot 1014 respectively. Unlocking requires step-by-step unlocking to prevent accidental falling off, thereby improving the reliability of the connecting rod.

[0046] Specifically, it includes a rod body 100, a connecting pipe 102 sleeved on one end of the rod body 100, and a connecting sleeve 101, wherein the connecting pipe 102 is movably sleeved with the connecting sleeve 101;

[0047] The rotating mechanism includes a rotating ring 200 rotatably sleeved on the outer wall of the connecting tube 102;

[0048] The double locking mechanism includes a first claw 300 and a second claw 301 which are opened on the outer wall of the connecting tube 102. The connecting sleeve 101 is locked with the first claw 300 and the second claw 301 at the same time. When the rotating ring 200 rotates, the second claw 301 is separated from the connecting sleeve 101. When the connecting sleeve 101 slides downward, it is pressed against the first claw 300, so that the first claw 300 is deformed and moved downward and separated from the connecting sleeve 101.

[0049] More preferably, in other embodiments, a conical sleeve may be used at the tip of the connecting tube 102 to assist in positioning and facilitate quick disassembly and assembly. A single-groove seven-section telescopic portion may be added to the rod body 100 to increase the telescopic length of the rod body 100 to adapt to different working scenarios.

[0050] In this embodiment, the rotating ring 200 is moved using a shift block. In other embodiments, the shift block can be replaced with a design such as anti-slip texture or a pentagonal nut shape to increase friction, making it easier for operators to rotate the rotating ring 200 while preventing it from slipping.

[0051] Among them, the rod body 100 is a hollow circular tube made of aluminum profile, the rotating ring 200 rotates along the outer wall of the connecting tube 102 and is limited and cannot slide up and down along the connecting tube 102. The first claw 300 and the second claw 301 are each provided with two sets and are symmetrically distributed about the connecting tube 102.

[0052] More preferably, the first claw 300, the second claw 301 and the connecting tube 102 are made of engineering plastics, and one end of the first claw 300 and the second claw 301 are fixed to the outer wall of the connecting tube 102. Since both are made of engineering plastics, they have elastic deformation capabilities within a certain range. In the initial state, the first claw 300 and the second claw 301 coincide with the outer wall of the connecting tube 102.

[0053] Preferably, a step 1023 is formed on the connecting tube 102 so that the diameter of the connecting tube 102 where the first claw 300 is located is smaller than the diameter of the connecting tube 102 where the second claw 301 is located, and the connecting sleeve 101 also has a step 1023 so as to fit with the step 1023 of the connecting tube 102 .

[0054] Preferably, the connecting tube 102 includes a first mosaic tube 1021 and a second mosaic tube 1022, a step 1023 is provided at the junction of the first mosaic tube 1021 and the second mosaic tube 1022, the first clamping claw 300 is opened on the first mosaic tube 1021, and the second clamping claw 301 is also opened on the first mosaic tube 1021 and extends to the second mosaic tube 1022.

[0055] More preferably, the connecting sleeve 101 includes a first fitting sleeve 1011 and a second fitting sleeve 1012 . A step 1023 is also provided at the junction of the first fitting sleeve 1011 and the second fitting sleeve 1012 and fits with the step 1023 of the connecting pipe 102 .

[0056] Among them, the first clamping claw 300 and the second clamping claw 301 also include a protrusion 3001 arranged on the outer wall thereof, and the first clamping sleeve 1011 and the second clamping sleeve 1012 are respectively provided with a first clamping groove 1013 and a second clamping groove 1014, and the first clamping groove 1013 and the second clamping groove 1014 are respectively movably engaged with the first clamping claw 300 and the second clamping claw 301 in the initial state.

[0057] The protrusion 3001 is in the shape of a prism with rounded corners, and is used to engage with the first slot 1013 and the second slot 1014 to limit the connection pipe 102 and the connection sleeve 101, thereby preventing them from falling off.

[0058] Preferably, the length of the first slot 1013 is greater than that of the second slot 1014 and the protrusion 3001, so that a slidable buffer area exists between the first slot 1013 and the protrusion 3001, and the first section is unlocked after the second claw 301 disengages from the second slot 1014, and the connecting tube 102 can slide freely for a certain distance and trigger the unlocking of the second section through the first claw 300 sliding in the first slot 1013.

[0059] Furthermore, a diameter-changing groove 2001 is opened on the inner wall of the rotating ring 200 , and the diameter-changing groove 2001 and the second clamping claw 301 fit each other, and the diameter-changing groove 2001 and the second clamping claw 301 fit together and press the second clamping claw 301 downward during rotation.

[0060] The variable diameter groove 2001 is a slot hole with a gradually decreasing diameter, so that the second claw 301 is squeezed and deformed downward during the rotation process, and the protrusion 3001 on the second claw 301 is disengaged from the second slot 1014, completing the unlocking of the first section.

[0061] Furthermore, a pit 1001 is provided at one end of the first clamping claw 300 located at the second interlocking tube 1022, and an extrusion block 1002 is provided at the lower end surface of the second clamping groove 1014. The extrusion block 1002 fits with the first clamping claw 300 in the pit 1001 and extrudes and deforms it downward.

[0062] Among them, after the second claw 301 disengages from the second slot 1014, the connecting sleeve 101 continues to move downward, causing the extrusion block 1002 to disengage from the second claw 301 and slide into the pit 1001 and contact and squeeze the first claw 300, and the first claw 300 deforms downward, so that the first claw 300 disengages from the first slot 1013, completing the unlocking of the second section.

[0063] Among them, a shift block is provided on the outer wall of the rotating ring 200, a guide groove 2002 is opened on the surface of the first engaging tube 1021, a guide strip is opened on the inner wall of the first engaging sleeve 1011, the guide strip is slidably engaged with the guide groove 2002, and a handle 2004 is provided on the end of the rod body 100 away from the connecting tube 102.

[0064] In summary, when in use, the first claw 300 and the second claw 301 are respectively limited and engaged with the first slot 1013 and the second slot 1014, so that a double interlocking engagement is achieved between the connecting tube 102 and the connecting sleeve 101. At this time, the connecting tube 102 and the connecting sleeve 101 cannot move at all. When unlocking is required, the shift block is rotated so that the smaller diameter area in the reducing groove 2001 contacts the second claw 301 and presses it downward, so that the protrusion 3001 on the second claw 301 disengages from the second slot 1014, completing the first re-unlocking.

[0065] At the same time, the connecting sleeve 101 is pushed to move downward, and the first claw 300 slides in the first slot 1013. In other embodiments, a spring is provided so that after the first re-unlocking of the connecting sleeve 101 is completed, the connecting sleeve 101 is automatically pushed downward; the extrusion block 1002 disengages from the second claw 301 and slides into the pit 1001 and contacts and squeezes the first claw 300, and at the same time, the protrusion 3001 on the first claw 300 also moves to the upper edge of the first slot 1013. As the first claw 300 deforms downward, the protrusion 3001 also moves downward and disengages from the first slot 1013, so that the first claw 300 disengages from the first slot 1013, completing the unlocking of the second section. Through double unlocking, the safety and reliability of the connection is guaranteed to prevent accidents such as accidental falling.

[0066] Example 2

[0067] Reference Figure 1 to Figure 9 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the rod body 100 can be extended and shortened by rotating the lever 4006 to adapt to various situations, and a connecting sleeve 101 is provided in the handle 2004, so that multiple connecting rods can be assembled with each other to achieve extension.

[0068] Specifically, the outer wall of the rod body 100 is sleeved with an adjustment platform 400 , and the rod body 100 is divided into an upper rod body 4001 and a lower rod body 4002 in the adjustment platform 400 . The upper rod body 4001 is fixedly connected to the adjustment platform 400 , and the lower rod body 4002 slides in the adjustment platform 400 .

[0069] More preferably, a connecting sleeve 101 is slidably provided inside the handle 2004 , and a lifting rod 4003 is slidably provided inside the rod body 100 . The lifting rod 4003 slidably passes through the handle 2004 and is fixedly connected to the connecting sleeve 101 .

[0070] Among them, a limit block is provided in the adjustment platform 400, which allows the lifting rod 4003 and the lower rod body 4002 to only slide up and down along the limit block in the adjustment platform 400 but cannot rotate. During operation, the adjustment platform 400 is held by hand, and the overall length of the rod body 100 is adjusted as the lower rod body 4002 and the lifting rod 4003 slide up and down.

[0071] Among them, when the length of the rod body 100 is still not enough after being adjusted to the maximum, the end cover of the handle 2004 is pulled open, and the lifting rod 4003 continues to move upward, so that the connecting sleeve 101 slides upward out of the handle 2004. At this time, the two connecting rods are connected up and down through the connecting sleeve 101 and the connecting tube 102, so as to splice a connecting rod of double length to increase the length of the rod.

[0072] More preferably, a slide groove 4004 is provided in the adjustment platform 400 , a slide plate 4005 is slidably provided in the slide groove 4004 , a lever 4006 is vertically provided on the slide plate 4005 , and an arc groove 4007 is further provided on the adjustment platform 4000 , and the lever 4006 slides along the arc groove 4007 .

[0073] Furthermore, a first slideway 4008 is formed on the lower rod body 4002 , a second slideway 4009 is formed on the lifting rod 4003 , and the shifting rod 4006 slides through the first slideway 4008 and the second slideway 4009 at the same time.

[0074] Among them, the first slide 4008 and the second slide 4009 are both spiral-shaped slots, and the lever 4006 slides along the first slide 4008 and the second slide 4009. The first slide 4008 and the second slide 4009 are symmetrically distributed about the lever 4006 to form an "eight" shape. When the lever 4006 moves to the central position, it forms an "X" shape. The lever 4006 slides to the right, causing the lower rod body 4002 and the lifting rod 4003 to move upward and downward respectively, so that the rod body 100 contracts and the length is reduced.

[0075] In summary, when the rod body 100 is too long and needs to be shortened, the lever 4006 is pushed to the right to rotate it counterclockwise, so that the slide 4005 rotates counterclockwise in the slide groove 4004, and the lifting rod 4003 and the lower rod body 4002 can only slide up and down along the limit block in the adjustment platform 400. As the lever 4006 rotates to the right in the first slide 4008, the lower rod body 4002 is pushed to move upward, and the lifting rod 4003 is pushed downward to achieve the length adjustment of the rod body 100.

[0076] At the same time, when the rod body 100 is still not long enough after being extended, open the end cover of the handle 2004, continue to rotate the lever 4006 to move the lifting rod 4003 upward, so that the connecting sleeve 101 slides upward out of the handle 2004, and the connecting tube 102 of another rod body 100 is locked and connected with it, thereby increasing the length of the rod body 100 and meeting various practical requirements.

[0077] For example, in other embodiments, the connecting tube 102 is provided with a threaded hole, and the lifting rod 4003 can be detachably connected to the connecting tube 102 through a thread. The disassembled connecting tube 102 can then be connected to scissors, probes and other instruments through the threaded hole, which is simple, convenient and efficient, and has a wide range of application scenarios.

[0078] Example 3

[0079] Reference Figure 1-Figure 10 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but is different in that, through the rotation of the control ring 4011 and the rotating ring 200, the placement and removal of objects from a high place can be achieved only by rotation, which is simple and convenient and has a wide range of application scenarios.

[0080] Specifically, a control ring 4011 is slidably sleeved on the outer wall of the rod body 100 , a connecting rod 4012 is provided between the control ring 4011 and the shifting rod 4006 , and the control ring 4011 is rotatably sleeved on the outer wall of the rotating ring 200 .

[0081] The control ring 4011 is also a hollow ring, and the connecting rod 4012 is made of hard plastic, so that the lever 4006 and the control ring 4011 rotate synchronously and cannot move up and down.

[0082] Furthermore, a tooth groove 2013 is formed in a circumferential array on the outer wall of the rotating ring 200 , a platform 4013 is fixedly provided on the control ring 4011 , a limit rod is slidably provided inside the platform 4013 , and the limit rod is slidably engaged in the tooth groove 2013 .

[0083] Among them, one end of the limiting rod is located at the tooth groove 2013 and is provided with a vertical surface 1015 and an inclined surface 1016. The other end of the limiting rod is provided with an adjustment cover 1017. A spring 4018 is provided between the adjustment cover 1017 and the platform 4013.

[0084] More preferably, a positioning rod 4019 is provided on the end surface of the adjustment cover 1017 , a positioning groove 4021 is formed on the platform 4013 , and the positioning rod 4019 slides along the positioning groove 4021 .

[0085] Among them, the spring 4018 pushes the limiting rod to slide downward into the tooth groove 2013, the positioning groove 4021 is a symmetrically arranged waist-shaped groove, and the positioning rod 4019 is a symmetrically arranged waist-shaped rod. After the positioning rod 4019 rotates 180°, it can still slide downward along the positioning groove 4021.

[0086] Preferably, the inclined surface 1016 is inclined at 45°, the tooth groove 2013 is a tooth-shaped groove, and the vertical surface 1015 is perpendicular to the inner wall of the tooth groove 2013, so that Figure 8 In the state shown, when the control ring 4011 rotates counterclockwise, the inclined surface 1016 slides along the inner wall of the tooth groove 2013 and enters the next tooth groove 2013, and the rotating ring 200 remains stationary.

[0087] Among them, during the clockwise rotation of the control ring 4011, the rotating ring 200 is driven to rotate synchronously through the vertical surface 1015, so that the first lock of the connecting tube 102 and the connecting sleeve 101 is released, and the rod body 100 continues to move downward to release the connection with the connecting sleeve 101. When the limit rod is pulled outward and rotated 180° to release it, the functions of the rotation directions are swapped.

[0088] More preferably, if Figure 8 In the initial state shown, in this embodiment, when the lever 4006 and the control ring 4011 rotate counterclockwise, the rod body 100 extends, and when they rotate clockwise, the rod body 100 shortens. Exemplarily, a spring is installed between the connecting sleeve 101 and the connecting tube 102. When the double locking is released, the connecting sleeve 101 can automatically pop out a certain distance.

[0089] In other embodiments, the connecting tube 102 can be made to slide in the variable stroke groove and cannot slide off directly, but slides to the middle position of the variable stroke groove, and then needs to further release the limit of the variable stroke groove before it can be removed, thereby improving the connection reliability of the device.

[0090] In summary, in the initial state, when the lever 4006 and the control ring 4011 rotate counterclockwise first, the length of the rod body 100 is extended. After the height meets the requirement, the control ring 4011 rotates clockwise, and drives the rotating ring 200 to rotate synchronously through the vertical surface 1015, so that the first lock of the connecting tube 102 and the connecting sleeve 101 is released. At the same time, the lever 4006 continues to be rotated clockwise, and the rod body 100 continues to move downward, thereby releasing the connection with the connecting sleeve 101, and the object is placed at a high place through the connecting sleeve 101.

[0091] At the same time, when the limit rod is pulled out and rotated 180° to release, the control functions of the rotation direction are swapped. Counterclockwise rotation connects the rod body 100 to the connecting sleeve 101, and clockwise rotation moves the rod body 100 upward. By rotating the limit rod and the lever, the object can be removed and placed through the connecting sleeve 101, which is simple and convenient.
