Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fixture, especially a special antenna fixture. BACKGROUND

[0002] The antenna support of a certain type of traditional vehicle antenna is connected to the antenna pole through an antenna clamp, and the antenna pole is clamped through two semicircular buckles under the action of a locking device. The two semicircular buckles are connected to the antenna support at the root. It is found in the use process that the antenna clamp design has great limitations. When the antenna clamp is tightly fixed with the antenna pole, the antenna direction cannot be changed at will. In order to adjust the antenna direction, the current solution is to change the vehicle head direction by the driver to meet the required antenna direction. When the driver adjusts the direction, the antenna must be lowered and withdrawn. After the direction adjustment is completed, it is re-erected. After a long time of changing direction, the antenna clamp is prone to aging, causing unstable antenna fixation, inaccurate direction, and other problems, which is very inconvenient to use in work and seriously delays work efficiency.

DETAILED DESCRIPTION

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figs. 1-6 One embodiment of this utility model is a special antenna clamp, which includes a first buckle 1, a second buckle 2 and an antenna bracket 3.

[0031] like Figs. 1-3 As shown, both the first buckle 1 and the second buckle 2 are semi-circular arc-shaped. Grooves are provided on the upper and lower surfaces of the first buckle 1 and the second buckle 2, forming an "H"-shaped cross-section with a concave center and two convex sections. When the first buckle 1 and the second buckle 2 form a complete ring, the upper and lower surfaces form a concave annular track. A pad 21 is fixed on the inner side of the first buckle 1 and the second buckle 2 to hold the antenna rod tightly when the complete annular structure formed by the first buckle 1 and the second buckle 2 is fitted onto the antenna rod. The pad 21 is made of wear-resistant material, which further enhances the contact area between the first buckle 1 and the second buckle 2 and the antenna rod, improves the clamping force, and reduces wear or damage caused by direct contact.

[0032] One end of the first buckle 1 and one end of the second buckle 2 are rotatably connected by a rotating shaft 20. A closing component is installed on the outside of the other end of the first buckle 1 and the other end of the second buckle 2. The closing component is used to lock the first buckle 1 and the second buckle 2.

[0033] The closure assembly is an existing tool, which is described in detail here: The closure assembly includes a latch 8 mounted on the first latch; a fixing plate 15 mounted on the second latch 2; a vertical plate 16 mounted on the outside of the fixing plate 15; a handle 17 rotatably connected to the vertical plate 16; a connecting post 18 connected to the bottom of the handle 17; and a U-shaped frame 19 rotatably connected to the connecting post 18. The U-shaped frame 19 can hook the latch 8 and rotate around the connecting post 18 under the action of the handle 17, thereby locking the first latch 1 and the second latch 2.

[0034] like Fig. 6 As shown, the antenna bracket 3 has a rectangular parallelepiped structure with a T-shaped through slot on the inner side for engaging with the first buckle 1 and the second buckle 2. A movement space for arranging locking clips 4 is provided between the upper and lower surfaces of the antenna bracket 3, and the movement space is connected to the T-shaped through slot.

[0035] The "I"-shaped part of the T-shaped through groove engages with the protruding edge of the first buckle 1 or the second buckle 2, and the "I"-shaped part of the T-shaped through groove engages with the grooves on the upper and lower surfaces of the first buckle 1 or the second buckle 2. Pin holes are provided on both sides of the "I"-shaped part of the T-shaped through groove, and a third pin 10 is installed in the pin holes and fixed by a snap ring 11. A deep groove ball bearing 9 is installed at the inner end of the third pin 10, which engages with the grooves on the upper and lower surfaces of the first buckle 1 or the second buckle 2, allowing the antenna bracket 3 to slide on the first buckle 1 or the second buckle 2. In this embodiment, the deep groove ball bearing 9 is a 60000 type deep groove ball bearing, whose hardness ensures that the antenna bracket with the deep groove ball bearing can still slide automatically even when the antenna is hung and subjected to wind and sand, ensuring that the antenna clamp system is not damaged.

[0036] like Figs. 1-5 As shown, two support plates 14 are fixed at the bottom of the antenna bracket 3 and on both sides of the motion space. A second pin 6 is fixedly installed between the two support plates 14, and a pull ring 13 is rotatably connected to the second pin 6. The pull ring 13 consists of two long strips of lugs, and the outer ends of the two long strips of lugs are connected by a thin rod. The thin rod is used to connect an external pull rope. The inner ends of the two long strips of lugs are fitted onto the second pin 6, and a torsion spring 7 is fitted onto the second pin 6 between the two long strips of lugs. One end of the torsion spring 7 is fixed to the pull ring 13, and the other end is fixed to the second pin 6. The torsion spring 7 can drive the pull ring 13 to rotate around the second pin 6. The inner sidewalls of the two long strips of lugs are connected to the second pin 6. The locking clip 4 is fixedly connected via a connecting rod. In this embodiment, the pull ring 13 and the locking clip 4 adopt an integral molding structure. The locking clip 4 is located in the movement space, and the inner surface of the locking clip 4 is a friction surface. When the locking clip 4 is tightly attached to the first buckle 1 or the second buckle 2 under the pre-tightening force of the torsion spring 7, it can fix the antenna bracket 3. When the operator pulls the thin rod with an external pull rope, the combination of the pull ring 13 and the locking clip 4 will overcome the pre-tightening force of the torsion spring 7 and rotate around the second pin 6, so that the friction surface of the locking clip 4 is separated from the first buckle 1 or the second buckle 2, thereby allowing the antenna bracket 3 to slide along the first buckle 1 or the second buckle 2.

[0037] Since the antenna bracket 3 is located on a high antenna mast during operation, in order to ensure that the antenna bracket 3 can be locked and unlocked on the first buckle 1 or the second buckle 2, the support plate 14 and the pull ring 13 are installed at the bottom of the antenna bracket 3. In this way, when the operator pulls the rope from below, pulling the rope down will unlock the locking clip 4 and adjust the antenna direction at the same time. After reaching the working position, the rope is released, and the locking clip 4 will automatically lock under the action of the torsion spring 7, thereby ensuring that the antenna cannot be arbitrarily changed after reaching the working direction.

[0038] Furthermore, the first pin shaft 5 is installed on the outer side end face of the antenna support 3 through a connecting lug, a wheel 12 is rotationally connected on the first pin shaft 5, and the wheel 12 is used for cooperation with other parts of the antenna.

[0039] The special antenna clamp provided by the utility model is designed through the grooves on the first buckle 1 and the second buckle 2, so that the antenna support 3 slides along the outside of the grooves, and then the position of the antenna support 3 can be adjusted; the support plate 14 provides a stable mounting platform for the pull ring 13; when the pull ring 13 is lifted through the external pull rope, the torsional spring 7 stores energy; at this time, the pull ring 13 drives the locking clamps 4 fixed at the inner end bottom to separate from the first buckle 1 or the second buckle 2, and the antenna support 3 can slide on the first buckle 1 or the second buckle 2, so that the position and direction of the antenna can be adjusted according to the requirement; after the pull ring 13 is loosened, the pre-tightening force of the torsional spring 7 makes the pull ring 13 reset, and then drives the locking clamps 4 fixed at the inner end bottom of the pull ring 13 to tightly adhere to the first buckle 1 or the second buckle 2.

[0040] Through the rolling friction between the deep groove ball bearing 9 and the upper and lower surfaces of the first buckle 1 or the second buckle 2, the antenna support 3 can slide on the first buckle 1 or the second buckle 2, and the antenna support 3 can reduce the friction and resistance when the direction is adjusted, so that the antenna can be pulled by the staff, the direction of the antenna is changed, the antenna clamp system is not damaged, the antenna is moved along the outside of the wheel 12 by pulling the antenna, and the integrity of the surface of the antenna is ensured.

[0041] Working principle: first, the first buckle 1 and the second buckle 2 are connected together through the rotating shaft 20, and the handle 17 is rotated, and then the connecting column 18 and the U-shaped frame 19 are rotated together; with the rotation of the U-shaped frame 19, the U-shaped frame 19 is clamped on one side of the lock catch 8, so that the first buckle 1 and the second buckle 2 are locked through the U-shaped frame 19 and the lock catch 8, and are fixed at the specified position of the antenna rod; at this time, the pull ring 13 is connected outside the first buckle 1 and the second buckle 2, then the pull ring 13 is pulled to lift and drive the locking clamps 4, so that the locking clamps 4 do not contact the outside of the first buckle 1 or the second buckle 2, and the antenna support 3 is driven to slide along the outside of the first buckle 1 and the second buckle 2 through the pull ring 13; when the pull ring 13 is adjusted to the required direction, the pull ring 13 is loosened, and then the pull ring 13 is reset under the pre-tightening force of the torsional spring 7, and then the locking clamps 4 tightly adhere to the outside of the first buckle 1 or the second buckle 2, so that the antenna support 3 is locked, and the direction of the antenna support 3 is not changed at will.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
