Description

Technical Field

[0001] This utility model relates to the technical field of satellite antenna support equipment, and in particular to a locking and adjusting mechanism for a satellite antenna support rod. Background Technology

[0002] Chinese Patent CN101635390B discloses an assembly mold for a truss-type spatial structure. The structure comprises: a base with several supports fixed on it, each support having a fine-tuning mechanism mounted at its top; the fine-tuning mechanism consists of: a fixed plate fixed to the top of the supports; an adjusting plate positioned above the fixed plate and fixed off-axis to it, and also off-axis to a circular base above it for horizontal adjustment; a lifting rod with its lower end fixed to the center of the circular base for vertical adjustment; and a ball-head support with a sphere at its bottom and a cylindrical support at its top. The sphere at its bottom is connected to a socket at the upper end of the lifting rod via a pressure cap, allowing the ball-head support to swing around this socket.

[0003] However, the above-mentioned assembly mold has the following drawbacks: the ball head support of the fine adjustment mechanism of the assembly mold lacks a locking device. When the satellite antenna is installed on the assembly mold, if the mold shakes unexpectedly, the satellite antenna will deform. This needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a locking and adjusting mechanism for a satellite antenna support rod, which can lock and release the ball head bolts and prevent the satellite antenna from shaking and deforming during placement.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a locking and adjusting mechanism for a satellite antenna support rod, comprising a base assembly, a top cover, and a ball head bolt. The top cover has an clearance hole corresponding to the ball head bolt, and the base assembly has an installation groove corresponding to the ball head bolt. The top cover can rotate relative to the base assembly between an unlocked state and a locked state. A plurality of locking rods are slidably disposed on the base assembly. Each locking rod has a guide post, and the top cover has a spiral guide groove corresponding to the guide post. The guide post and the spiral guide groove guide and cooperate to drive the plurality of locking rods closer to each other and lock the ball head bolt, or drive the plurality of locking rods further apart and release the ball head bolt.

[0006] By adopting the above technical solution, when the ball head bolt is connected to the bottom of the satellite antenna, the top cover can be screwed on. The spiral guide groove of the top cover and the guide post guide force will make multiple locking rods relatively close to each other on the base assembly and lock the ball head bolt, preventing the ball head bolt from shaking when positioning and supporting the satellite antenna. When it is necessary to adjust the position of the support rod, the top cover can be screwed on in the unlocking direction. The spiral guide groove and the guide post guide force will again make multiple locking rods relatively far apart on the base assembly and release the ball head bolt. Then the height of the support rod can be adjusted, preventing the ball head bolt from tightening and causing component deformation when adjusting the height of the support rod. It has the effect of locking and releasing the ball head bolt and preventing shaking and deformation during the placement of the satellite antenna.

[0007] A further feature of this invention is that the radius of curvature of the spiral guide groove gradually decreases from the distal end of the top cover toward the proximal end.

[0008] By adopting the above technical solution, when the top cover rotates in the locking or unlocking direction, it can drive multiple locking rods to move closer or further apart through the corresponding spiral guide groove.

[0009] A further feature of this invention is that the base assembly includes a base plate and a base plate fixed to the base plate. The mounting groove is opened in the middle of the base plate. The base plate has a plurality of linear trajectory grooves communicating with the mounting groove in the radial direction. The locking rod is slidably disposed in the corresponding linear trajectory groove.

[0010] By adopting the above technical solution, when the top cover rotates, the locking rod can slide along the length of the straight track groove through the guiding cooperation of the spiral guide groove and the guide post.

[0011] A further feature of this invention is that the ball head bolt includes a threaded portion and a ball head, the ball head extending into the mounting groove. When the top cover rotates relative to the base assembly to the locked state, a plurality of locking rods abut against the outer wall of the threaded portion, so that the locking rods and the ball head are anti-disengaged.

[0012] By adopting the above technical solution, the ball head bolts, which are locked by multiple locking rods, can be securely connected to the support rod and the satellite antenna, preventing the ball head bolts from detaching from the base assembly.

[0013] A further feature of this invention is that the locking rod has a guide slope at one end near the ball head bolt, and the ball head is guided into the mounting groove through the guide slope.

[0014] By adopting the above technical solution and adding the guide slope, the installation efficiency of ball head bolts on the base assembly can be improved.

[0015] A further feature of this invention is that the base assembly further includes a support base, which is fixedly connected to the base plate and located at the bottom of the mounting groove. The support base has a positioning groove corresponding to the ball head, and a plurality of positioning ribs are provided in the positioning groove. The ball head extends into the positioning groove and cooperates with the positioning ribs for positioning and support.

[0016] By adopting the above technical solution, multiple positioning ribs can effectively support the ball head of the ball head bolt, thereby improving the support of the base assembly for the ball head bolt.

[0017] A further feature of this invention is that the positioning ribs are provided with supporting inclined surfaces corresponding to the ball head, and the supporting inclined surfaces of the plurality of positioning ribs are positioned and engaged with the outer wall of the ball head.

[0018] By adopting the above technical solution, multiple supporting inclined surfaces cooperate to form the profile of the positioning ball head, which enables the ball head to be accurately installed in the predetermined position of the support base. At the same time, the ball head can rotate on the profile formed by multiple supporting inclined surfaces, which is beneficial to adjusting the depth of the threaded connection of the ball head bolt on the outer wall of the satellite antenna, and improving the assembly accuracy and convenience of the ball head bolt.

[0019] A further feature of this invention is that: an annular groove is provided on the side wall of the base plate, and an annular extension is provided on the edge of the top cover facing downward. An installation hole is provided on the annular extension corresponding to the annular groove. A guide block is installed in the installation hole, and the end of the guide block extends out of the installation hole and slides in a guiding manner with the annular groove.

[0020] By adopting the above technical solution, it is possible to prevent the top cover from detaching from the base plate, and at the same time, it is possible to improve the consistency of the rotation direction of the top cover on the base plate.

[0021] A further feature of this invention is that a mounting seat is fixedly provided on the base assembly, and an elastic positioning structure is provided between the mounting seat and the top cover. When the top cover rotates relative to the base assembly to a locked state or an unlocked state, the top cover and the mounting seat are positioned and engaged by the elastic positioning structure.

[0022] By adopting the above technical solution, when the top cover is in a locked or unlocked state relative to the mounting base, the top cover can be kept in the corresponding position with the mounting base through the elastic positioning structure.

[0023] A further feature of this invention is that the elastic positioning structure includes an elastic element, a stop bead, and a locking hole. The mounting base is provided with a mounting cylinder with an opening facing the top cover. The mounting cylinder has a receiving groove. The elastic element and the stop bead are disposed in the receiving groove. The locking hole is opened on the side wall of the top cover corresponding to the stop bead. The elastic element has a tendency to push the stop bead to elastically press against the locking hole.

[0024] By adopting the above technical solution, when the top cover rotates between the locked and unlocked states, the abutment retracts into the receiving groove of the mounting cylinder and compresses the elastic element. When the top cover rotates relative to the base assembly to the position corresponding to the locked or unlocked state, the abutment aligns with the lock hole. At this time, the elastic element releases its elastic force and pushes the abutment to press against the corresponding lock hole. Due to the collision, a "tick" sound is emitted to indicate that the assembly is in place, which is used to prompt the operator to turn the top cover to the locked or fully unlocked state.

[0025] In summary, this utility model has the following beneficial effects:

[0026] The system employs a top cover that rotates onto the base assembly. The top cover has clearance holes, and the base assembly has mounting slots. The ball head of the ball end bolt passes through the clearance holes and extends into the mounting slot. The base assembly has several linear grooves running radially, each containing a sliding locking rod. Each locking rod has a guide post, and the top cover has a corresponding helical guide groove. The guide post and helical guide groove engage to either move the locking rods closer together to lock the ball end bolt, or move them further apart to release the ball end bolt. When the ball end bolt is connected to the bottom of the satellite antenna, it can be connected by screwing on the top cover, utilizing the helical guide groove of the top cover and the guide post. The guiding force of the guide column causes multiple locking rods to approach each other on the base assembly and lock the ball head bolts, preventing the ball head bolts from shaking when positioning the satellite antenna. When the position of the support rod needs to be adjusted, the top cover can be turned in the unlocking direction. The guiding force of the spiral guide groove and the guide column is used again to move the multiple locking rods away from each other on the base assembly and release the ball head bolts. Then the height of the support rod can be adjusted. This prevents the ball head bolts from tightening and causing deformation of the components when adjusting the height of the support rod. It has the effect of locking and releasing the ball head bolts and preventing shaking and deformation during the placement of the satellite antenna. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] A locking and adjusting mechanism for a satellite antenna support rod, such as Figures 1-4 As shown, the assembly includes a base assembly 1, a top cover 2, and a ball head bolt 3. The top cover 2 has a clearance hole 21 corresponding to the ball head bolt 3, and the base assembly 1 has a mounting groove 121 corresponding to the ball head bolt 3. The top cover 2 can rotate relative to the base assembly 1 between an unlocked state and a locked state. Several locking rods 4 are slidably arranged on the base assembly 1. Each locking rod 4 has a guide post 41. The top cover 2 has a spiral guide groove 22 corresponding to the guide post 41. The guide post 41 and the spiral guide groove 22 guide and cooperate to drive the locking rods 4 closer together and lock the ball head bolt 3, or drive the locking rods 4 further apart and release the ball head bolt 3. In this embodiment, there are three spiral guide grooves 22. The clearance hole 21 is opened at the center of the top cover 2. The three spiral guide grooves 22 are evenly distributed on the top cover 2 with the clearance hole 21 as the center. The radius of curvature of the spiral guide groove 22 is from the top cover. The top cover 2 gradually decreases in size from the distal end to the proximal end, so that when the top cover 2 rotates in the locking or unlocking direction, it can drive multiple locking rods 4 to move closer or further apart through the corresponding spiral guide groove 22; the base assembly 1 includes a base plate 11 and a base plate 12 fixed on the base plate 11. The mounting groove 121 is opened in the middle of the base plate 12. The base plate 12 has a plurality of linear trajectory grooves 122 that connect to the mounting grooves 121 in the radial direction. The locking rods 4 are slidably set in the corresponding linear trajectory grooves 122, so that when the top cover 2 rotates, it can drive the locking rods 4 to slide along the length direction of the linear trajectory grooves 122 through the guiding cooperation of the spiral guide groove 22 and the guide post 41; it should be noted that in this embodiment, the base assembly 1 is rotatably connected to the end of the support rod, and the support rod has a lifting adjustment function, which can adjust the height of the support rod appropriately according to the needs of the scenario.

[0034] like Figures 2-4As shown, the ball head bolt 3 includes a threaded portion 31 and a ball head 32. The ball head 32 extends into the mounting groove 121. When the top cover 2 rotates relative to the base assembly 1 to the locked state, several locking rods 4 abut against the outer wall of the threaded portion 31, so that the locking rods 4 and the ball head 32 are anti-detached. This allows the ball head bolt 3, locked by multiple locking rods 4, to securely connect the support rod and the satellite antenna, preventing the ball head bolt 3 from detaching from the base assembly 1. The locking rod 4 has a guide slope 42 at one end near the ball head bolt 3. The ball head 32 is guided into the mounting groove 121 through the guide slope 42. The addition of the guide slope 42 helps to improve the installation efficiency of the ball head bolt 3 on the base assembly 1. The base assembly 1 also includes a support base 13, which is fixedly connected to the base plate 11 and located at the bottom of the mounting groove 121. The support base 13 has a fixed opening corresponding to the ball head 32. The positioning groove 131 has several positioning ribs 132. The ball head 32 extends into the positioning groove 131 and is positioned and supported by the positioning ribs 132. The multiple positioning ribs 132 can effectively support the ball head 32 of the ball head bolt 3, improving the support of the base assembly 1 for the ball head bolt 3. The positioning ribs 132 have supporting inclined surfaces 1321 corresponding to the ball head 32. The supporting inclined surfaces 1321 of the multiple positioning ribs 132 are positioned and cooperate with the outer wall of the ball head 32. The multiple supporting inclined surfaces 1321 cooperate to form the profile of the positioning ball head 32, so that the ball head 32 can be accurately installed in the predetermined position of the support base 13. At the same time, the ball head 32 can rotate on the profile formed by the multiple supporting inclined surfaces 1321, which is beneficial to adjust the depth of the threaded connection of the ball head bolt 3 on the outer wall of the satellite antenna, improving the assembly accuracy and convenience of the ball head bolt 3.

[0035] like Figures 1-4As shown, the base plate 12 has an annular groove 123 on its side wall, and the top cover 2 has an annular extension 23 with its edge facing downward. The annular extension 23 has a mounting hole 231 corresponding to the annular groove 123. A guide block 232 is installed in the mounting hole 231, and the end of the guide block 232 extends out of the mounting hole 231 and slides in a guide-sliding engagement with the annular groove 123. This prevents the top cover 2 from detaching from the base plate 12 and also improves the consistency of the rotation direction of the top cover 2 on the base plate 12. A mounting seat 5 is fixed on the base assembly 1, and an elastic positioning structure is provided between the mounting seat 5 and the top cover 2. When the top cover 2 rotates relative to the base assembly 1 to a locked or unlocked state, the top cover 2 and the mounting seat 5 are positioned and engaged by the elastic positioning structure, so that when the top cover 2 is in a locked or unlocked state relative to the mounting seat 5, the top cover 2 can be held in the corresponding position by the elastic positioning structure. The mounting base 5 includes an elastic element 512, a stop bead 513, and a locking hole 24. The mounting base 5 has a mounting cylinder 51 with an opening facing the top cover 2. The mounting cylinder 51 has a receiving groove 511. The elastic element 512 and the stop bead 513 are located in the receiving groove 511. The locking hole 24 is opened on the side wall of the top cover 2 corresponding to the stop bead 513. The elastic element 512 has a tendency to push the stop bead 513 to elastically press against the locking hole 24. When the top cover 2 rotates between the locked and unlocked states, the stop bead 513 retracts into the receiving groove 511 of the mounting cylinder 51 and compresses the elastic element 512. When the top cover 2 rotates relative to the base assembly 1 to the position corresponding to the locked or unlocked state, the stop bead 513 aligns with the locking hole 24. At this time, the elastic element 512 releases its elastic force and pushes the stop bead 513 to press against the corresponding locking hole 24. Due to the collision, a "tick" sound is emitted to indicate that the top cover 2 has been screwed into the locked or fully unlocked state.

[0036] The basic working principle of this utility model is as follows: A top cover 2 is rotatably mounted on the base assembly 1. The top cover 2 has a clearance hole 21. The base assembly 1 has a mounting groove 121. The ball head 32 of the ball head bolt 3 passes through the clearance hole 21 and extends into the mounting groove 121. Several linear trajectory grooves 122 are formed radially on the base assembly 1. A locking rod 4 is slidably mounted in each linear trajectory groove 122. The locking rod 4 has a guide post 41. The top cover 2 has a spiral guide groove 22 corresponding to the guide post 41. The guide post 41 and the spiral guide groove 22 guide and cooperate to drive the locking rods 4 to move closer to each other and lock the ball head bolt 3, or to drive the locking rods 4 to move away from each other and release the ball head bolt 3. When the ball head bolt 3 is connected to the bottom of the satellite antenna, it can be... By screwing on the top cover 2, the spiral guide groove 22 of the top cover 2 and the guide post 41 guide force make the multiple locking rods 4 relatively close on the base assembly 1 and lock the ball head bolt 3, preventing the ball head bolt 3 from shaking when positioning and supporting the satellite antenna. When it is necessary to adjust the position of the support rod, the top cover 2 can be screwed in the unlocking direction. Again, the spiral guide groove 22 and the guide post 41 guide force make the multiple locking rods 4 relatively far apart on the base assembly 1 and release the ball head bolt 3. Then the height of the support rod can be adjusted, preventing the ball head bolt 3 from locking and causing the component to deform when adjusting the height of the support rod. It has the effect of locking and releasing the ball head bolt and preventing the satellite antenna from shaking and deforming during placement.

[0037] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
