Description

Technical Field

[0001] The invention relates to the field of mobile communication equipment, and in particular to a pitch angle adjuster of a spotlight antenna. Background Art

[0002] Spotlight antennas have wide-angle radiation characteristics and can transmit or receive signals at a larger angle. They are often used in wireless communication systems and are suitable for signal coverage of large areas such as squares, parking lots, and stadiums. In order to achieve the best signal coverage, spotlight antennas are usually installed on elevated structures, such as the top of a building or on a bracket. The spotlight antenna pitch angle adjuster is a mechanism that adjusts the pitch angle of the spotlight antenna and fixes its pitch angle.

[0003] When installing the spotlight antenna, its pitch angle needs to be adjusted. Since the conventional spotlight antenna itself cannot automatically measure the angle, it is impossible to accurately reach the design angle during the adjustment process. It can only rely on experience and judgment, resulting in large errors. In addition, during the use of the antenna, external forces may cause angle deviation, but it is difficult to detect this deviation in a timely and accurate manner, which brings challenges to subsequent maintenance. Although positioning can be done with the help of other auxiliary tools, this will also increase construction costs and reduce efficiency; the prior art has proposed a good solution to this problem, such as the spotlight antenna pitch angle adjustment device with patent number CN210326140U, which hinges the side of the spotlight antenna body on the spotlight support for rotation adjustment. The spotlight antenna body is fixed with a circular dial with a rotation angle on the side near the hinge end parallel to the rotation plane. A pointer that can rotate freely relative to the circular dial is hung at the axis of the circular dial. The needle of the pointer is always vertically downward under the action of gravity, and then the degree is read while adjusting.

[0004] Although the existing technology has solved the problem that the adjustment angle cannot be measured during the adjustment process and can only be judged by experience, resulting in large errors, the following problems still exist: when the pitch angle adjuster of the spotlight antenna is used to adjust the angle, the spotlight antenna needs to be swung to the required angle, and after swinging to the required angle, the bolts are tightened to complete the fixation. During this process, manual adjustment cannot complete the angle adjustment accurately to the single digit, and when locking, it is necessary to manually support the spotlight antenna and tighten the bolts to fix it. This will result in a certain deviation angle when the spotlight antenna is fixed due to insufficient stability of manual support, thereby causing the signal coverage effect of the spotlight antenna to deteriorate.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention provides a pitch angle adjuster for a spotlight antenna. Summary of the invention

[0006] The present invention provides a pitch angle adjuster for a spotlight antenna, which solves the problem that it is difficult to maintain the precision and accuracy of the spotlight antenna during and after the adjustment of the angle. By improving the adjustment mechanism, the spotlight antenna can be accurately adjusted to small degrees and will not deflect after the adjustment is completed. A locking assembly and a transmission assembly are provided, so that the transmission assembly drives the locking assembly to stabilize the adjustment of the spotlight antenna angle. After the adjustment is completed, the spotlight antenna can be locked quickly and can provide stable support and a good rotation restriction effect after locking.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A pitch angle adjuster for a spotlight antenna, comprising an adjusting mechanism, a locking mechanism and a supporting mechanism; the adjusting mechanism comprises a handle, an adjusting wheel train and a connecting assembly; the handle is arranged at the left end of the spotlight antenna; the adjusting wheel train is connected to the handle, the left end of the connecting assembly is connected to the adjusting wheel train, and the right end is connected to the spotlight antenna; the rotation of the handle drives the adjusting wheel train to rotate, the rotation of the adjusting wheel train drives the connecting assembly to rotate, the rotation of the connecting assembly drives the spotlight antenna to rotate, and the adjusting speed and the adjusting amplitude are reduced by the adjusting wheel train, so as to accurately adjust the rotation angle of the spotlight antenna; the locking mechanism comprises a locking assembly, a pressure stop assembly and a transmission assembly; the locking assembly is arranged at the right end of the spotlight antenna; the pressure stop assembly is arranged at the spotlight antenna The left end of the line; the transmission assembly is connected between the adjustment mechanism and the locking assembly; the rotation of the handle drives the transmission assembly to pull the locking assembly to the left to press the right end of the spotlight antenna, and drives the pressure stop assembly to press the connecting assembly to complete the limit, thereby completing the fixation of the spotlight antenna and limiting its rotation, reducing the angular deviation during the locking process; the supporting mechanism includes a fixing plate, an adjustment support and a locking support; the fixing plate is directly connected to the ground or wall by bolts for fixation; the adjustment support is installed on the left side of the fixing plate; the locking support is installed on the right side of the fixing plate; considering that it is outdoors, a cover can be added to the adjustment mechanism, the locking mechanism and the supporting mechanism for protection to prevent rainwater from seeping in and causing rust on the parts and causing the angle to shift.

[0009] Preferably, the adjusting gear train includes a rotating shaft, a sun gear, a ring gear and a planetary gear; the left end of the rotating shaft is connected to the handle, and a transmission groove is provided on the rotating shaft; the sun gear is mounted on the right end of the rotating shaft; the ring gear is fixedly mounted on a fixed plate, and its axis is located on the same axis as the rotating shaft; the planetary gear is meshed with the sun gear and the ring gear, and the modules of the planetary gear, sun gear and ring gear are equal, and the number of teeth of the sun gear is less than or equal to A, the number of teeth of the planetary gear is greater than or equal to B, and the number of teeth of the ring gear is greater than or equal to C, and A is less than B, and C is greater than or equal to 180.

[0010] In the above scheme, the angle is adjusted by setting an adjusting gear train. On the one hand, the number of teeth of the ring gear can be set to accurately control the angle that the spotlight antenna rotates each time a tooth is rotated, thereby improving the accuracy of the pitch angle adjustment of the spotlight antenna; on the other hand, the engagement between the gears can ensure that after rotating to the desired angle, the spotlight antenna will not deviate in angle when the handle is not turned or the spotlight antenna is swung forcefully, and it can be fixed for a short time, so that the locking process will not cause the spotlight antenna to deviate in angle. When the number of teeth on the sun gear is much smaller than the number of teeth on the planetary gear, the orbital speed of the planetary gear can be slowed down, thereby improving the angle adjustment accuracy.

[0011] Preferably, the connecting assembly includes a planetary carrier rod, a center rotating rod and a radial connecting rod; the left end of the planetary carrier rod is connected to the planetary gear; the center rotating rod is rotatably mounted on an adjusting support, the left end of which is connected to the planetary carrier rod, and its axis coincides with the axis of the sun gear; the left end of the radial connecting rod is connected to the center rotating rod, and the right end is connected to the spotlight antenna.

[0012] In the above scheme, by setting a planetary carrier rod and a center rotating rod, and placing the center rotating rod on the same axis as the sun gear, the angle of rotation of the planetary gear is equal to the angle of rotation of the spotlight antenna, which is convenient for using a motor to directly adjust the rotation angle; the center rotating rod and the spotlight antenna are fixedly connected radially by a radial connecting rod to ensure that the rotation angles of the two are the same, thereby avoiding relative rotation between the center rotating rod and the spotlight antenna, which causes rotation errors.

[0013] Preferably, an arc block is provided at the right end of the radial connecting rod; a connecting platform is provided on the left side of the spotlight antenna; a driving screw hole is provided on the side wall of the connecting platform; the inner wall radius of the arc block is equal to the outer wall radius of the connecting platform, and a connecting screw hole is provided on the arc block; the inner wall diameters of the connecting screw hole and the driving screw hole are equal.

[0014] In the above scheme, an arc block is provided at the right end of the radial connecting rod, and is connected to the connecting platform on the left side of the spotlight antenna with screws. The screw connection is used to drive the spotlight antenna to rotate. Compared with the direct axial fixed connection between the center rotating rod and the spotlight antenna, it can provide a larger torque, and thus it is easier to rotate the spotlight antenna when the handle is turned. In addition, the arc block can improve the support of the spotlight antenna, so that the spotlight antenna can be stably supported when subjected to external force, ensuring that it does not flip over.

[0015] Preferably, the locking assembly includes a locking platform, a locking pressure rod and a locking push rod; the locking platform is arranged on the right side surface of the spotlight antenna; the locking pressure rod is slidably installed on the locking support and is coaxially arranged with the locking platform; the locking push rod is slidably installed on the locking pressure rod; the transmission assembly includes a transmission connecting rod, a transmission sleeve and a stop spring; the transmission connecting rod is connected to the locking assembly; the transmission sleeve is connected to the rotating shaft and cooperates with the transmission groove; the stop spring is connected between the transmission sleeve and the transmission connecting rod.

[0016] In the above scheme, a locking platform and a locking pressure rod are provided so that when the locking pressure rod is pushed to the left, a force pushing the spotlight antenna to the left is exerted to fix it axially, thereby limiting the rotation of the spotlight antenna; the transmission sleeve and the left end of the rotating shaft form a ball screw structure, and the transmission sleeve is driven to move to the left by rotating the rotating shaft, so that when the handle is rotated, the locking assembly will slide toward the spotlight antenna and provide a smaller friction force, so that the spotlight antenna is more stable and precise when rotating.

[0017] Preferably, a locking protrusion is provided on the outer wall of the locking platform; a plurality of locking protrusions are provided and arranged in a circular array, and a sliding fillet is provided on the right end of the locking protrusion; the locking pressure rod includes a sliding round rod and a locking pressure block; the outer wall diameter of the sliding round rod is equal to the inner wall diameter of the locking platform; the inner wall of the locking pressure block is provided with a locking groove matching the locking protrusion; and a connecting fillet is provided on the outer side of the locking groove.

[0018] In the above scheme, a locking protrusion is provided on the outer ring of the locking platform, and a locking groove matching the locking protrusion is provided on the inner wall of the locking pressure block, so that after the two are pressed and matched, the locking pressure block is restricted from rotating, which can limit the rotation of the locking platform and the spotlight antenna; at the same time, by setting the sliding fillet and the connecting fillet, it is easier to insert the two into the mating state when they are in contact, avoiding the rotation of the spotlight antenna or the inability to be smoothly inserted during mating due to misalignment.

[0019] Preferably, a friction surface is provided on the right end face of the locking block; the locking push rod includes a clamping end, a sliding end and a supporting end; a locking surface is provided on the left side of the clamping end; the locking surface is made of carbon fiber material and has a rough surface; the sliding end is slidably mounted on a fixed plate; the supporting end is connected between the clamping end and the sliding end.

[0020] In the above scheme, a friction surface is set at the right end of the locking block and a locking surface is set at the left side of the clamping end, so that the two cannot rotate relative to each other after they are in contact and clamped, and the locking surface is made of carbon fiber material, which can provide a large friction force while maintaining a long service life. The friction force is so large that normal external wind force and manual bending of the human body cannot affect the pitch angle of the spotlight antenna.

[0021] Preferably, the sliding end includes a vertical sliding rod, a limiting slider and a limiting spring; a limiting sliding groove is provided on the fixed plate; a limiting card groove is provided at the tail of the limiting sliding groove; the vertical sliding rod is slidably installed in the limiting sliding groove, and the limiting slider is slidably installed at the bottom of the vertical sliding rod; the limiting spring is connected between the vertical sliding rod and the limiting slider.

[0022] In the above scheme, by setting a limit slider, when the sliding end slides to the bottom of the limit slide groove, the limit slider enters the limit slot under the action of the limit spring to complete the limiting action, thereby limiting the clamping end, so that the clamping end presses the locking block, and the locking block presses the locking platform.

[0023] Preferably, the pressure stop assembly includes a driving slide rod, a pressure stop clamp block, a pressure stop connecting rod, a compression spring, a pressure stop rotating rod and a limit block; the driving slide rod is slidably connected to the fixed plate; the pressure stop clamp block is composed of two half clamp blocks; the inner wall diameter of the half clamp block is larger than the diameter of the center rotating rod; the compression spring is connected between the two half clamp blocks; there are two pressure stop connecting rods, which are respectively connected to the two half clamp blocks; the upper end of the pressure stop rotating rod is connected to the pressure stop connecting rod; the limit block is arranged on the right side of the pressure stop connecting rod.

[0024] In the above scheme, by setting a pressure-stop clamp, before the pressure-stopping is performed, since the inner wall diameter of the half clamp is larger than the diameter of the center rotating rod, and the compression spring is used to hold the two half clamps apart, it will not interfere with the adjustment angle of the spotlight antenna, and the inner wall diameter of the half clamp is set to be within 5mm larger than the diameter of the center rotating rod. When the pressure-stopping is performed after the adjustment, the center rotating rod can be quickly clamped to prevent the center rotating rod from rotating, thereby avoiding the angle deflection of the spotlight antenna.

[0025] Preferably, a driving inclined plane is arranged at the left end of the driving slide rod, and the inclination direction of the driving inclined plane is the upper left direction of the left end surface of the driving slide rod; and a driving fillet is arranged at the bottom of the pressure stop rod.

[0026] In the above scheme, by setting the driving fillet and the driving inclined plane, when the driving inclined plane moves to the left, the driving fillet is pressed to drive the anti-rotation rod to rotate, thereby completing the locking action. The driving inclined plane is set to have an inclination direction of the upper left direction of the left end face of the driving slide rod, so that when the driving inclined plane squeezes the driving fillet, the rotation angle of the anti-rotation rod gradually increases, thereby enhancing the clamping effect and limiting the rotation of the spotlight antenna.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. Compared with the existing pitch angle adjusters of spotlight antennas, the existing pitch angle adjusters of spotlight antennas need to manually adjust the angle of the spotlight antenna and use bolts to lock it, which will cause small angle errors during the adjustment and locking processes; the present invention sets an adjustment gear system to adjust the pitch angle of the spotlight antenna through gear transmission, which can make small angle adjustments and improve the accuracy of the adjustment angle; on the other hand, gear meshing is used to ensure that the spotlight antenna will not deflect by a small angle during the locking process after the adjustment is completed, thereby further improving the accuracy of the pitch angle of the spotlight antenna and ensuring the signal coverage effect of the spotlight antenna.

[0029] 2. The present invention provides a locking assembly. On the one hand, the sliding end is used to slide the limit slider into the limit slot to achieve a quick locking effect, which is faster than traditional bolt locking, thereby reducing the offset angle generated during the locking process; on the other hand, a locking platform is provided on the spotlight antenna, and a locking convex surface is provided on the locking platform, and a locking groove matching the locking convex block is provided on the inner wall of the locking pressure block, so that the locking platform and the locking pressure block are matched, and the locking pressure rod is used to press to achieve its rotation limit, so that the spotlight antenna after the limit is less likely to deflect at an angle when receiving a rotational force, and when the handle is rotated, the transmission assembly moves to the left to drive the locking assembly to slide toward the spotlight antenna, providing less friction, making the spotlight antenna more stable and precise when rotating, and ensuring that the pitch angle of the spotlight antenna will not change during the subsequent locking process, thereby ensuring the signal coverage effect of the spotlight antenna.

[0030] 3. The present invention sets a pressure stop component. On the one hand, the driving slide rod pushes the pressure stop rod to rotate, so that the driving pressure stop rod rotates, thereby driving the pressure stop clamp to quickly clamp the center rod, preventing the center rod from rotating, thereby avoiding the angle deflection of the spotlight antenna; on the other hand, the slope of the driving inclined surface is increased obliquely, so that the stroke of the pressure stop rod is increased and it is completely pressed, so that the pressure stop clamp is clamped more tightly, and the driving slide rod is completely limited by the limiting slider, thereby ensuring that the pressure stop clamp always maintains a pressure stop state, ensuring that the spotlight antenna will not rotate, and improving the accuracy of the pitch angle adjustment of the spotlight antenna.
