Description

Technical Field

[0001] This invention relates to the field of radio communication technology, and more specifically to an adjustable telescopic sleeve and its adjustment method. Background Technology

[0002] In vehicle-mounted mobile communication systems, high-power whip antennas are among the most commonly used antennas for shortwave communication. They are composed of multiple sections of metal tubes with progressively decreasing diameters, connected one after another, including the end connections of adjacent metal tubes and the connections between retractable metal sleeves. Existing connection devices between multiple retractable metal sleeves with diameters ranging from φ18mm to φ35mm are complex in structure, making it inconvenient to pull out and fix the metal sleeves and retract them, resulting in low reliability and failing to meet the requirements for rapid pulling out and rapid retraction of multiple metal sleeves.

[0003] The prior art proposes a Chinese patent with publication number CN102709667B to solve the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: A telescopic sleeve quick-release device includes an inner tube, an outer tube, an inner tube telescopic positioning mechanism, and an inner tube extension limiting mechanism. The lower end of the inner tube is provided with a pair of inner tube straight grooves, and the upper end of the outer tube is provided with a pair of outer tube straight grooves corresponding to the inner tube straight grooves. The inner tube telescopic positioning mechanism includes a pair of positioning claws, a compression spring, and a positioning claw support shaft. The positioning claw support shaft is fixed inside the lower end of the inner tube. An axial groove is opened at the upper end of the positioning claw support shaft. A pair of positioning claws are symmetrically arranged in the axial groove, and their upper ends are hinged to the upper end of the positioning claw support shaft. The compression spring is arranged on the inner middle part of the pair of positioning claws. The inner tube extension limiting mechanism is arranged at the upper end of the inner tube telescopic positioning mechanism. This invention features a compact structure, ease of use, and high reliability. It solves the problem of rapid deployment and retraction of a set of telescopic metal sleeves consisting of two sections within the diameter range of φ18mm to φ35mm for multi-section whip antennas, thus meeting the requirements of systems engineering.

[0004] The above technical solution will have the following problems in actual use:

[0005] While this existing technology can solve the problem of rapid deployment and retraction of telescopic metal sleeves in pairs within the diameter range of φ18mm to φ35mm for multi-section whip antennas, thus meeting the requirements of systems engineering, its overly complex structure leads to high construction and subsequent maintenance costs, hindering its widespread adoption. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] An adjustable telescopic sleeve and its adjustment method are provided, comprising the following two aspects:

[0008] First aspect: The present invention provides a technical solution: an adjustable telescopic sleeve, including a main body device, the main body device including a telescopic unit, an assembly unit and a locking unit.

[0009] The telescopic unit includes an external sleeve, an internal telescopic tube, and a push block for adjusting the position of the internal telescopic tube. The assembly unit includes a positioning collar and a positioning frame. The locking unit includes an auxiliary arc block, a first return spring, a second return spring, a limiting arc plate, a locking handle, an irregular arc block, and a locking rod.

[0010] The outer wall of the external sleeve has a vertical pushing groove, and the outer wall of the internal telescopic tube has a positioning hole for inserting the locking rod. The internal telescopic tube is located inside the external sleeve.

[0011] The above technical solution utilizes the combination of positioning collar, external sleeve, limiting arc plate, locking rod, irregular arc block and locking handle to enable the built-in telescopic tube to be quickly adjusted. Moreover, the device has a simple structure and saves construction and subsequent maintenance costs.

[0012] A further improvement of the technical solution of the present invention is that: the inner wall of the external sleeve is slidably connected to the outer wall of the built-in telescopic tube, the bottom outer wall of the built-in telescopic tube is fixedly connected to one side of the push block, and the outer wall of the push block is slidably connected to the inner wall of the vertical push groove.

[0013] Using the above technical solution, in this solution

[0014] A further improvement of the technical solution of the present invention is that: the bottom inner wall of the positioning collar is fixedly connected to the top outer wall of the external sleeve, the outer wall of the positioning collar is fixedly connected to one side of the positioning frame, and the irregular arc block is rotatably connected to the inner wall of the positioning frame through the shaft end.

[0015] The above technical solution utilizes the combination of positioning collar and auxiliary arc block to enable the built-in telescopic tube to provide positioning and clamping function during the limiting and positioning process of the restricted arc plate, thereby improving the stability of the built-in telescopic tube.

[0016] A further improvement of the technical solution of the present invention is that: one side of the limiting arc plate is movably connected to the outer wall of the irregular arc block, and the center of the inner wall of the limiting arc plate is fixedly connected to one end of the locking rod.

[0017] A further improvement of the technical solution of the present invention is that: the outer wall of the irregular arc block is fixedly connected to one end of the locking handle, one side of the limiting arc plate is fixedly connected to one end of the first reset spring, the other end of the first reset spring is fixedly connected to one side of the auxiliary arc block, and the bottom end of the auxiliary arc block is fixedly connected to the top end of the external sleeve.

[0018] The above technical solution utilizes the combined use of two sets of first and second reset springs, so that when the irregular arc block releases the thrust on the limiting arc plate, the limiting arc plate can drive the locking rod to reset under the action of elasticity, thereby simultaneously releasing the restriction on the built-in telescopic tube and further facilitating the adjustment of the built-in telescopic tube.

[0019] Secondly, the present invention provides a technical solution: an adjustable telescopic sleeve adjustment method, which includes the following steps:

[0020] Step 1: Unlock;

[0021] Step 2: Adjust positioning.

[0022] A further improvement to the technical solution of the present invention is that: the unlocking in step one includes the following steps:

[0023] A: The operator holds the locking handle and rotates the irregular arc block around its axis, causing the irregular arc block to rotate and lift. This releases the pressure of the irregular arc block on the limiting arc plate. At this time, the limiting arc plate will be pushed by the reaction force of multiple sets of first and second return springs, which will cause the locking rod on the limiting arc plate to move outward, so that the locking rod is pulled out from the inner wall of the positioning hole, releasing the limitation on the built-in telescopic tube.

[0024] A: During the process of adjusting the locking throttle, the staff holds the push block with one hand and applies an upward pushing force to balance the weight on it.

[0025] A further improvement to the technical solution of the present invention is that the positioning adjustment in step two includes the following steps:

[0026] B: After the limiting arc plate releases the restriction on the built-in telescopic tube, the worker pushes the push block up the inner wall of the outer sleeve until it reaches the appropriate position and stops. Then, the worker turns the locking handle, causing the irregular arc block to rotate around the shaft. The irregular arc block uses its protruding part to push the limiting arc plate, so that the locking rod installed in its inner wall is inserted into the positioning hole, restricting the built-in telescopic tube and thus completing the adjustment work.

[0027] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0028] 1. This invention provides an adjustable telescopic sleeve and its adjustment method. By using a positioning collar, an external sleeve, a limiting arc plate, a locking rod, an irregular arc block and a locking handle in combination, the built-in telescopic sleeve can be quickly adjusted. Moreover, the device has a simple structure and saves construction and subsequent maintenance costs.

[0029] 2. This invention provides an adjustable telescopic sleeve and its adjustment method. By using two sets of first and second return springs in cooperation, when the irregular arc block releases the thrust on the limiting arc plate, the limiting arc plate can drive the locking rod to reset under the action of the elastic force, thereby simultaneously releasing the restriction on the built-in telescopic tube and further facilitating the adjustment of the built-in telescopic tube.

[0030] 3. The present invention provides an adjustable telescopic sleeve and its adjustment method. By using the combination of positioning collar and auxiliary arc block, the built-in telescopic sleeve can provide positioning and clamping function during the limiting and positioning process of the restricted arc plate, thereby improving the stability of the built-in telescopic sleeve.

[0038] The present invention will be further described in detail below with reference to embodiments:

[0039] Example 1

[0040] Firstly, such as Figure 1-6 As shown, the present invention provides an adjustable telescopic sleeve, including a main body device 1, which includes a telescopic unit, an assembly unit, and a locking unit.

[0041] The telescopic unit includes an outer sleeve 2, an inner telescopic tube 4, and a push block 14 for adjusting the position of the inner telescopic tube 4. The assembly unit includes a positioning collar 3 and a positioning frame 5. The locking unit includes an auxiliary arc block 8, a first return spring 9, a second return spring 10, a limiting arc plate 6, a locking handle 7, an irregular arc block 11, and a locking rod 12. By using the cooperation of each component, the inner telescopic tube 4 can be quickly adjusted. Moreover, the device has a simple structure, saving construction and subsequent maintenance costs.

[0042] The outer wall of the outer sleeve 2 is provided with a vertical pushing groove 15, and the outer wall of the inner telescopic tube 4 is provided with a positioning hole 13 for inserting and locking the plug rod 12. The inner telescopic tube 4 is located inside the outer sleeve 2.

[0043] The inner wall of the outer sleeve 2 is slidably connected to the outer wall of the built-in telescopic tube 4, the bottom outer wall of the built-in telescopic tube 4 is fixedly connected to one side of the push block 14, and the outer wall of the push block 14 is slidably connected to the inner wall of the vertical push groove 15.

[0044] The bottom inner wall of the positioning collar 3 is fixedly connected to the top outer wall of the outer sleeve 2, the outer wall of the positioning collar 3 is fixedly connected to one side of the positioning frame 5, and the irregular arc block 11 is rotatably connected to the inner wall of the positioning frame 5 through the shaft end.

[0045] Example 2

[0046] like Figure 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: preferably, one side of the limiting arc plate 6 is movably connected to the outer wall of the irregular arc block 11, and the center of the inner wall of the limiting arc plate 6 is fixedly connected to one end of the locking rod 12. The locking rod 12 installed on one side of the limiting arc plate 6 is divided into three groups, which are distributed at equal intervals from top to bottom, corresponding to the distribution of the positioning holes 13 on the built-in telescopic tube 4.

[0047] The outer wall of the irregular arc block 11 is fixedly connected to one end of the locking handle 7. One side of the limiting arc plate 6 is fixedly connected to one end of the first return spring 9, and the other end of the first return spring 9 is fixedly connected to one side of the auxiliary arc block 8. The cooperation of the two sets of first return springs 9 and second return springs 10 allows the limiting arc plate 6 to be able to drive the locking rod 12 to reset under the action of the elastic force when the irregular arc block 11 releases the pushing force on the limiting arc plate 6. This allows the limiting arc plate 6 to release the restriction on the built-in telescopic tube 4 at the same time, further facilitating the adjustment of the built-in telescopic tube 4. The bottom end of the auxiliary arc block 8 is fixedly connected to the top end of the outer sleeve 2. The cooperation of the positioning collar 3 and the auxiliary arc block 8 allows the built-in telescopic tube 4 to provide a positioning and clamping function during the limiting process of the limiting arc plate 6, thereby improving the stability of the built-in telescopic tube 4.

[0048] Example 3

[0049] Secondly, such as Figure 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: an adjustable telescopic sleeve adjustment method, which includes the following steps:

[0050] Step 1: Unlock;

[0051] Step 2: Adjust positioning.

[0052] Unlocking in step one includes the following steps:

[0053] A1: The operator holds the locking handle 7 and makes it rotate around the axis of the irregular arc block 11, causing the irregular arc block 11 to rotate and lift, so that the compression and pushing of the irregular arc block 11 on the limiting arc plate 6 is released. At this time, the limiting arc plate 6 will be pushed by the reaction force of multiple sets of first return springs 9 and second return springs 10, which will drive the locking rod 12 on the limiting arc plate 6 to move outward, so that the locking rod 12 is pulled out from the inner wall of the positioning hole 13, releasing the limitation on the built-in telescopic tube 4;

[0054] A2: During the process of adjusting the locking throttle 7, the staff holds the push block 14 with one hand and applies an upward pushing force to it to balance the weight it is subjected to.

[0055] Step two, adjusting the positioning, includes the following steps:

[0056] B1: After the limiting arc plate 6 releases the restriction on the built-in telescopic tube 4, the worker pushes the push block 14 up the inner wall of the outer sleeve 2 until it reaches the appropriate position and stops. Then, the worker turns the locking handle 7, which drives the irregular arc block 11 to rotate around the shaft. The irregular arc block 11 uses its protruding part to push the limiting arc plate 6, so that the locking rod 12 installed in its inner wall is inserted into the positioning hole 13, which restricts the built-in telescopic tube 4 and thus completes the adjustment work.

[0057] The working principle of this adjustable telescopic sleeve will be explained in detail below.

[0058] like Figure 1-6As shown, during use, the operator holds the locking handle 7 to rotate and lift the irregular arc block 11 around its axis, thus releasing the pressure exerted by the irregular arc block 11 on the limiting arc plate 6. At this time, the limiting arc plate 6, under the reaction force of multiple sets of first return springs 9 and second return springs 10, will move the locking rod 12 on the limiting arc plate 6 outward, causing the locking rod 12 to be pulled out from the inner wall of the positioning hole 13, releasing the restriction on the built-in telescopic tube 4. During the adjustment of the locking handle 7, the operator holds the handle with one hand. Block 14 is pushed upward to balance its weight. After the limiting arc plate 6 releases the restriction on the built-in telescopic tube 4, the worker pushes the push block 14 to move up the inner wall of the outer sleeve 2 until it stops at the appropriate position. Then, the worker turns the locking handle 7 to drive the irregular arc block 11 to rotate around the shaft. The irregular arc block 11 uses its protrusion to push the limiting arc plate 6, so that the locking rod 12 installed in its inner wall is inserted into the positioning hole 13 to restrict the built-in telescopic tube 4, thereby completing the adjustment work.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0060] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
