DETAILED DESCRIPTION

[0039] The technical scheme in the utility model is further explained below in connection with the drawings and embodiments.

[0040] Embodiment 1

[0041] The embodiment is basically as Figure 1 , Figure 2 ,Figure 3 and Figure 4 As shown, this utility model embodiment proposes a locking structure with anti-retraction elastic locking structure, including a locking unit installed between two adjacent rods. The locking unit includes a sleeve 10, two locking seats 20, a locking pin 40, a locking handle 50, and a spring 601. The sleeve 10 is annular and is coaxially fixedly installed on one end of the rod. A first locking hole is provided radially on the outer wall of the other end of the rod.

[0042] like Figure 1 and Figure 2 As shown, the end of the locking pin 40 can pass through the locking seat 20 radially along the sleeve 10 and be detachably connected to the first locking hole of the adjacent rod. The locking seat 20 forms an installation cavity 201 for the locking pin 40 to slide horizontally and a limiting hole 202 located on the end face of the locking seat 20 away from the rod.

[0043] like Figure 1 and Figure 2 As shown, a rotation control structure is provided between the locking seat 20 and the locking pin 40 for rotating locking, axial movement, or rotation unlocking of the locking pin 40. The rotation control structure includes a limiting slide member 402, which is fixedly installed on the outer wall of the middle part of the locking pin 40. The locking seat 20 is provided with a limiting slide groove 203 for the limiting slide member 402 to slide along. The limiting slide groove 203 includes a rotation locking groove 213, an axial movement groove 223, and a rotation unlocking groove 233 connected in sequence. The rotation locking groove 213 and the rotation unlocking groove 233 are both arranged circumferentially around the locking seat 20, and the axial movement... The groove 223 is arranged along the axial direction of the locking seat 20. The limiting sliding member 402 can abut against the side wall of the rotating locking groove 213 and the rotating unlocking groove 233. The limiting sliding member 402 can slide in contact with the side wall of the rotating locking groove 213, the axial movement groove 223 or the rotating unlocking groove 233. The rotating locking groove 213 is located at the end of the locking seat 20 near the rod. The locking handle 50 is located at the end of the locking pin 40 away from the rod. The locking handle 50 and the locking pin 40 form an "L" shape, which makes it easy to judge the engagement state of the locking pin 40 and the first locking hole by judging the orientation of the locking handle 50.

[0044] like Figure 1 and Figure 2 As shown, the locking seat 20 has an integrally formed mounting flange 204 at one end near the rod. The mounting flange 204 has several first mounting holes 205. The sleeve 10 has several second mounting holes on its circumference that can be fitted and connected with the first mounting holes 205. Fixing members 30 are detachably installed at the first mounting holes 205 and the second mounting holes. The fixing members 30 are bolts.

[0045] At the same time, such as Figure 3As shown, the middle of the locking pin 40 is integrally formed with a ring-shaped protrusion 401, which is coaxially arranged with the locking pin 40, and the outer wall of the protrusion 401 can be in sliding contact with the inner wall of the mounting cavity 201 of the locking seat 20; the limiting sliding member 402 is a limiting screw, which is fixedly installed at the protrusion 401 and is arranged at the radial direction of the protrusion 401;

[0046] As shown in Figure 3 , the spring 601 is coaxially arranged outside the locking pin 40 and located in the mounting cavity 201, and the left end of the spring 601 abuts against the right end of the protrusion 401; when the limiting sliding member 402 is located in the rotation unlocking groove 233, the spring 601 is in the maximum compression state.

[0047] As shown in Figure 1 and Figure 2 , the circumferential outer wall of the sleeve 10 is provided with a plurality of second locking holes 101 for embedding the end part of the adjacent rod locking pin 40.

[0048] In use, the sleeve 10 is installed on the end part of the rod, and then the entire anti-exit elastic locking structure is installed on the rod. When the anti-exit elastic locking structure is used to lock a plurality of sequentially connected rods in an extended state, the rods are sequentially extended, and when the first locking hole on the rod is opposite to the end part of the locking pin 40, the locking handle 50 is held by hand, the locking handle 50 drives the locking pin 40 to rotate, the protrusion 401 and the limiting sliding member 402 move along the rotation unlocking groove 233 to the axial movement groove 223, at this time the locking pin 40 also rotates circumferentially relative to the mounting cavity 201 of the locking seat 20; when the limiting sliding member 402 moves to the axial movement groove 223, the spring 601 is relaxed in the axial direction, and the spring 601 pushes the protrusion 401 and the limiting sliding member 402 to move to the rotation locking groove 213, at this time the end part of the locking pin 40 has been embedded into the first locking hole; when the locking pin 40 is further locked, the locking handle 50 is held by hand again, the locking handle 50 drives the locking pin 40 to rotate, so that the locking pin 40 and the protrusion 401 drive the limiting sliding member 402 to rotate and be clamped into the rotation locking groove 213, the rotation locking groove 213 provides the limiting sliding member 402, the protrusion 401 and the locking pin 40 with axial limitation of the locking seat 20; from top to bottom, repeat the operation until the plurality of rods are expanded to the required height, at this time the plurality of locking handles 50 all point vertically upward.

[0049] When the rod is loosened and folded, the user holds the locking handle 50, reversely rotates and pulls out the locking pin 40, so that the locking pin 40 and the protrusion 401 press the spring 601, the limiting sliding part 402 retreats into the rotation unlocking groove 233, the locking pin 40 exits from the first locking hole, and at this time, the locking handles 50 are all directed downward; then the rod is folded, and the use of the elastic locking structure with anti-exit is convenient.

[0050] When the rod is loosened and folded, the user holds the locking handle 50, reversely rotates and pulls out the locking pin 40, so that the locking pin 40 and the protrusion 401 press the spring 601, the limiting sliding part 402 retreats into the rotation unlocking groove 233, the locking pin 40 exits from the first locking hole, and at this time, the locking handles 50 are all directed downward; then the rod is folded, and the use of the elastic locking structure with anti-exit is convenient. Figure 4 When the rod is loosened and folded, the user holds the locking handle 50, reversely rotates and pulls out the locking pin 40, so that the locking pin 40 and the protrusion 401 press the spring 601, the limiting sliding part 402 retreats into the rotation unlocking groove 233, the locking pin 40 exits from the first locking hole, and at this time, the locking handles 50 are all directed downward; then the rod is folded, and the use of the elastic locking structure with anti-exit is convenient.

[0051] In the above process, the locking handle 50 rotates or pulls out the locking pin 40, and then the locking pin 40 can quickly adjust the locking and loosening of the rod. In this process, the limiting sliding part 402 cooperates with the rotation locking groove 213, the axial movement groove 223 and the rotation unlocking groove 233 to realize the quick switching of the rotation locking state, the axial movement state and the rotation unlocking state. The rotation locking groove 213, the axial movement groove 223 and the rotation unlocking groove 233 can accurately lock the locking pin 40 in place.

[0052] When the locking pin 40 is locked with the first locking hole, in the case of radial compression, forced or rod wind shaking, the locking pin 40 cannot exit along the axial direction of the locking pin 40 under the cooperation of the rotation locking groove 213 and the limiting sliding part 402, which avoids the existing elastic locking mechanism from being caused by compression, force or rod wind shaking, and the locking pin 40 exits and fails, thereby improving the safety of the elongated rod locking.

[0053] Meanwhile, the limiting slide groove 203 of the locking seat 20 is divided into a rotary locking groove 213, an axial movement groove 223, and a rotary unlocking groove 233. The limiting sliding member 402 on the locking pin 40 can slide within the rotary locking groove 213, the axial movement groove 223, and the rotary unlocking groove 233. The locking pin 40 is rigidly connected to the locking handle 50. The locking handle 50 can indicate the state of the locking mechanism. The operator can easily determine which of the three states the locking mechanism is in—rotary locking, axial movement, or rotary unlocking—by pointing the locking handle 50, thus reducing the difficulty of operation. This avoids the situation where the existing locking mechanism collapses after the rod extends because the locking pin 40 is not fully inserted into the lower first locking hole due to the difficulty of judgment and operator error.

[0054] Example 2

[0055] The main differences between Example 2 and Example 1 are as follows: Figure 5 As shown, this invention aims to provide a lifting rod, including a top section tube 70, several bottom section tubes 80 that can be coaxially sleeved, and a locking structure with anti-removal elastic locking structure as in Embodiment 1. The top section tube 70 is sleeved 10 inside the innermost bottom section tube 80, and the sleeves 10 are all installed at the upper end of the bottom section tube 80. The locking seat 20 is located outside the top end of the corresponding bottom section tube 80. The first locking hole is located at the lower end of the top section tube 70 and the bottom section tube 80. The upper outer wall of the top section tube 70 is provided with a third locking hole 701 for the end of the locking pin 40 to be inserted.

[0056] like Figure 4 As shown, the second locking hole 101 on the sleeve 10 is directly opposite the locking seat 20 on the adjacent sleeve 10; the number of the second locking hole 101 and the locking seat 20 on a single sleeve 10 is two, and the second locking hole 101 and the locking seat 20 on a single sleeve 10 are evenly spaced; the end faces of two adjacent sleeves 10 can fit together.

[0057] In this embodiment, when the lifting rod is retracted, the retraction and locking of several bottom sections 80 are as shown in Embodiment 1. The limiting sliding member 402 is slid into the axial movement groove 223, so that the locking pin 40 is locked into the second locking hole 101 on the adjacent sleeve 10. However, in the top section 70, the limiting sliding member 402 on the top section tube is slid into the rotating locking groove 213, so that the locking pin 40 can be locked into the third locking hole 701 of the top section 70, thereby achieving stable retraction and locking of the top section 70. The overall retraction of the lifting rod is stable and convenient, making the retracted lifting rod shorter and easier to move.

[0058] Meanwhile, after the lifting rod is folded, the end faces of two adjacent sleeves 10 can fit together, which can further reduce the overall length of the lifting rod. During the folding and support process, the distribution of the second locking hole 101 and the locking seat 20 makes the force at the sleeve 10 more uniform and stable, which can improve the support performance of the lifting rod when it is extended, and also improve the tightness of the fit between the various structures after folding.

[0059] Example 3

[0060] The main differences between Example 3 and Example 2 are as follows: Figure 6 As shown, this invention aims to provide an equipment support system, including a mounting top plate 90 for installing lightning protection equipment or communication equipment and a lifting rod as described in Embodiment 2. The mounting top plate 90 is disc-shaped and is integrally formed on the top end of the top section tube 70.

[0061] In this embodiment, the equipment support system expands the connection and support area between the lightning protection equipment or communication equipment and the top section pipe 70 when in use. This allows the lightning protection equipment or communication equipment to be installed on the top plate 90 more reliably, thereby enabling the lifting rod to support the lightning protection equipment or communication equipment more stably and making the use of the lightning protection equipment or communication equipment more reliable.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
