The present disclosure provides a spot light antenna that facilitates angle adjustment. Referring to fig. 1 to 3, the spot lamp antenna for facilitating the adjustment of an angle includes a base 100, a first angle adjusting assembly 200, and an antenna assembly 300; wherein, the base 100 is provided with a containing cavity 101 and a first connecting hole communicated with the containing cavity 101; the first angle adjusting assembly 200 includes a gear plate 210, a bayonet 220, and an elastic member 230 that are engaged with each other; the gear plate 210 is accommodated in the accommodating cavity 101; the bayonet 220 is slidable in the radial direction of the gear plate 210; the elastic member 230 is used to allow the bayonet 220 to be partially inserted into the tooth slot of the gear plate 210 to lock the gear plate 210. The antenna assembly 300 includes an antenna body 330 and a first rotation shaft 320 connected to the antenna body 330; the antenna body 330 is located outside the base 100, and the first rotation shaft 320 passes through the first connection hole and is coaxially connected with the gear plate 210.

In the spot light antenna convenient for angle adjustment provided by the present disclosure, the antenna assembly 300 is connected with the gear plate 210 through the first rotation shaft 320, so whether the angle between the antenna assembly 300 and the base 100 is locked can be controlled by controlling whether the gear plate 210 can rotate. In a normal use state, the bayonet 220 is inserted into the tooth slot of the gear plate 210 under the action of the elastic member 230, so that the gear plate 210 cannot rotate and is locked. At this time, the gear plate 210 is in a locked state, so that the angle between the antenna assembly 300 and the base 100 is locked, which is beneficial to maintaining the radiation angle of the antenna assembly 300. When it is desired to adjust the radiation angle of the antenna assembly 300, the bayonet 220 may be pulled outward so that the bayonet is no longer inserted into the slot of the gear plate 210, and thus the gear plate 210 is in a rotatable state. At this time, the angle between the antenna assembly 300 and the base 100 is adjustable, and the antenna assembly 300 may be rotated to adjust the radiation angle thereof. After the angle between the antenna assembly 300 and the base 100 is adjusted, the bayonet 220 may be released. The bayonet 220 is reinserted into the slot of the gear plate 210 by the elastic member 230 so that the angle between the antenna assembly 300 and the base 100 is locked.

Thus, the angle-adjustable spot light antenna of the present disclosure may be configured such that the angle between the antenna assembly 300 and the base 100 is adjustable by pulling the bayonet 220, either during or after installation; and locks the angle between the antenna assembly 300 and the base 100 by releasing the bayonet 220. So, the shot-light antenna of angle regulation of being convenient for of this disclosure can conveniently adjust the contained angle between antenna module 300 and the base 100, and then conveniently adjusts the radiation angle scope of antenna body 330, easy operation, convenient to use has improved the debugging installation effectiveness of shot-light antenna.

The structure, principle and effect of the spot lamp antenna convenient for angle adjustment provided by the present disclosure are further explained and illustrated below with reference to the accompanying drawings.

Referring to fig. 1 and 2, the spot light antenna of the present disclosure has a base 100 for fixedly coupling with a mounting base surface (e.g., a base surface for fixing the spot light antenna such as a wall surface, a ceiling surface, a bracket surface, etc.). The base 100 may include a housing and a mounting foot plate 140 located at one side of the housing, and the mounting foot plate 140 is provided with a mounting hole 141. At the time of installation, the base 100 and the installation base surface may be connected by a connection member (e.g., a bolt, a screw, etc.) penetrating through the installation hole 141. Further, the mounting hole 141 may be oblong holes, and the extending directions of the oblong holes are the same. This facilitates adjustment of the relative position between the base 100 and the mounting base surface, as well as mounting of the base. In one embodiment of the present disclosure, the number of the mounting foot plates 140 is two and located on the same plane, and the housing is sandwiched between the two mounting foot plates 140; any one of the mounting foot plates 140 is provided with two oblong holes, and the extending directions of the oblong holes are the same. Thus, the base 100 can be stably installed, and the position thereof can be conveniently adjusted.

The housing has a side wall 110 surrounding the accommodating chamber 101, and a top wall 120 covering one end of the accommodating chamber 101, the top wall 120 being fixedly connected with the side wall 110. In other words, the housing has an open end, and the top wall 120 is disposed opposite to the open end. The mounting foot plate 140 is fixed to the side wall 110 and is located at the open end side of the housing. In this way, when the spotlight antenna is mounted, the open end of the accommodating cavity 101 may be covered by the mounting base surface, so that the accommodating cavity 101 is closed, and thus each part (for example, the gear disc 210, etc.) located in the accommodating cavity 101 can be protected. Of course, in other embodiments of the present disclosure, the housing may also include a bottom wall disposed opposite the top wall 120 to enclose the receiving cavity 101.

The base 100 may be provided with a first connection hole penetrating the top wall 120, and the first connection hole may communicate the outside of the base 100 with the receiving chamber 101. In one embodiment of the present disclosure, when the gear plate 210 is accommodated in the accommodating cavity 101, the plane of the gear plate 210 may be parallel to the top wall 120, and the gear plate 210 and the first connection hole may be coaxially disposed. Further, the first rotating shaft 320 is disposed through the first connecting hole and connected to the gear plate 210, and the first rotating shaft 320, the first connecting hole and the gear plate 210 may be coaxially disposed.

Alternatively, referring to fig. 2, the bayonet 220 may include a connecting rod 222 and a bayonet rack 221 connected to each other. The clamping rack 221 is disposed near one end of the gear plate 210, and is capable of being meshed with the gear plate 210. When the tooth portion of the locking rack 221 is inserted between the tooth grooves of the gear plate 210, the locking rack 221 is engaged with the gear plate 210, so that the gear plate 210 cannot rotate and is locked. When the engagement rack 221 is pulled outward (on the side away from the gear plate 210), the tooth portions of the engagement rack 221 are withdrawn from between the tooth grooves of the gear plate 210, and the gear plate 210 can be rotated.

The connection rod 222 is connected with the clamping rack 221 to control whether the clamping rack 221 is engaged with the gear plate 210. In some embodiments, the extending direction of the connecting rod 222 is parallel to the plane of the gear disc 210, so as to facilitate controlling the clamping rack 221.

Optionally, a blocking wall 130 is further disposed in the accommodating cavity 101, and the blocking wall 130 may be fixed to the housing of the base 100, for example, fixed to the top wall 120 or the side wall 110. The side wall 110 is provided with a first restriction hole; the blocking wall 130 is provided with a second restriction hole. The connecting rod 222 is disposed through the first restraining hole and the second restraining hole, and is capable of sliding in the first restraining hole and the second restraining hole. As such, the first and second restraining holes may constitute a track restraining the connecting rod 222, and the connecting rod 222 slides in its extending direction under the restraint of the track. The connecting rod 222 cannot be displaced in a direction perpendicular to the extending direction thereof under the constraint of the first constraint hole and the second constraint hole, thereby enabling the connecting rod 222 to move intelligently in a direction approaching or moving away from the gear plate 210 (radial direction of the gear plate). Thus, when the engagement rack 221 is engaged with the gear plate 210, the engagement rack 221 cannot move to lock the gear plate 210. In this embodiment, the end of the connecting rod 222 (the end remote from the snap rack) passes through the first restraining hole to be located outside the side wall 110, i.e., the end of the connecting rod 222 is located outside the base 100. In this way, the operator can control whether the gear plate 210 is locked or not through the end of the connecting rod 222.

In one embodiment of the present disclosure, the first constraining hole and the second constraining hole are disposed coaxially and have their axes parallel to the plane of the gear plate 210. Further, the axes of the first and second constricting holes pass through the gear plate 210.

In the present disclosure, the first and second constricting holes may be shaped to match the cross-sectional shape of the connecting rod 222 to facilitate the constriction of the connecting rod 222. The shape of the connecting rod 222 may be circular, square, rectangular, oval, or other shape. Further, the cross-sectional shape of the connecting rod 222 may be square or rectangular. In this way, the first restraining hole and the second restraining hole can further prevent the connecting rod 222 from rotating circumferentially, so that the clamping rack 221 is kept stable.

Alternatively, the elastic member 230 has one end connected to the side wall 110 or the blocking wall 130 and the other end connected to the connecting rod 222 to apply a force to the connecting rod 222 toward the gear plate 210. In this way, under no external force control, the elastic member 230 can make the clamping rack 221 abut against the gear plate 210, so as to lock the gear plate 210. Further, the elastic member 230 may be a spring, and particularly, may be a compression spring.

In one embodiment of the present disclosure, the connecting rod 222 has a blocking portion 223; the blocking portion 223 is disposed along a circumferential direction of the connection rod 222 and protrudes from a rod body of the connection rod 222. Wherein the blocking portion 223 may be located between the side wall 110 and the blocking wall 130. The elastic member 230 is a compression spring, and the compression spring is sleeved on the connecting rod 222 and located between the side wall 110 and the blocking portion 223. Thus, one end of the compression spring abuts against the side wall 110, and the other end abuts against the blocking portion 223, so as to continuously apply an elastic force to the connecting rod 222 towards the gear plate 210.

Optionally, the first angle adjustment assembly 200 further comprises a handle 250. The handle 250 is located at the outside of the base 100 and is fixed to the end of the connection rod 222, i.e., the handle 250 is located at the end of the connection rod 222. In this way, the handle 250 can control the connecting rod 222, and thus the gear plate 210, to be locked or not. Further, the extending direction of the handle 250 is perpendicular to the extending direction of the connecting rod 222.

Further, the first angle adjustment assembly 200 also includes an abutment post 240. One end (hinged end) of the abutment lever 240 is hinged to the handle 250, and the other end (free end) can abut against the side wall 110. When the spotlight antenna is mounted or adjusted, the connecting rod 222 can be pulled outwards by the handle 250, so that the relative angle between the antenna assembly 300 and the base 100 can be adjusted. After the connecting rod 222 is pulled open, the abutting rod 240 can be adjusted, so that the free end of the abutting rod 240 abuts against the side wall 110, and further, the connecting rod 222 is prevented from shrinking toward the accommodating cavity 101 of the base 100 under the action of the elastic member 230, and the gear disc 210 is kept in a rotatable state. Thus, the operator does not need to continuously pull the handle 250 by hand, which is beneficial to the installation and debugging of the spotlight antenna and saves manpower. On the gear plate 210 that needs to be locked, the abutment lever 240 can be rotated, so that the abutment lever 240 no longer abuts against the sidewall 110, and the connecting rod 222 can be retracted, so that the gear plate 210 is locked. In the present disclosure, the length of the interference lever 240 may be set as required so as to enable the gear plate 210 to maintain a rotatable state.

Optionally, referring to fig. 1, the antenna assembly 300 further includes a rotating bracket 310; the antenna body 330 and the first rotation shaft 320 are fixed to the rotation bracket 310. Specifically, the rotating bracket 310 has a bottom supporting wall 311, and the bottom supporting wall 311 is supported on the top wall 120 and connected to the first rotating shaft 320. The carrier bottom wall 311 is rotatable along the axis of the first rotation shaft 320 under the constraint of the first rotation shaft 320. When the mounting foot plate 140 is mounted on a horizontal mounting base surface, the radiation angle range of the antenna body 330 can be adjusted in the horizontal direction by rotating the first rotating shaft 320.

In one embodiment of the present disclosure, the base 100 further includes a boss 121 protruding toward one side of the rotating bracket 310, and the first connection hole passes through the boss 121; the rotating bracket 310 is carried on the surface of the boss 121 away from the gear plate 210. Specifically, the top wall 120 is provided with a boss 121 protruding toward a side away from the accommodating chamber 101, and the size of the boss 121 is not larger than that of the top wall 120. The bearing bottom wall 311 of the rotating bracket 310 may bear on the surface of the boss 121. In this way, the contact surface between the bottom bearing wall 311 and the boss 121 can be reduced, so that the friction resistance between the bottom bearing wall 311 and the boss is reduced, and the angle adjustment between the rotating bracket 310 and the base 100 is easier.

In one embodiment of the present disclosure, referring to fig. 2, the base 100 has a plurality of first angle scales 260 surrounding the first connection hole; the plurality of first angle scales 260 are equally spaced along a circular track coaxial with the first connection hole. The rotating bracket 310 is provided with a first indication mark 313 for cooperating with the first angle scale 260. Based on the scale value of the first angle scale 260 indicated by the first indication mark 313, a relative angle between the rotating bracket 310 and the base 100 can be determined, and an adjusted angle value can be determined. Further, referring to fig. 2, the first angle scale 260 may be disposed on an upper surface (a surface close to the rotating bracket 310) of the boss 121, and the first indication mark 313 may be disposed on the bearing bottom wall 311. In one example of the present disclosure, the first indication mark 313 may be an indication arrow, and the direction of the indication arrow is perpendicular to the extending direction of the bearing bottom wall 311 and passes through the axis of the first rotation shaft 320.

Optionally, referring to fig. 2, the base 100 further includes at least one first arcuate aperture 122 concentric with the first connecting aperture; the antenna assembly 300 further includes a connection support 360 corresponding to each of the first arc holes 122; the connection support 360 is connected to the rotation bracket 310, passes through the corresponding first arc hole 122, and is connected to the gear plate 210. In this embodiment, the first arc-shaped hole 122 is used to pass through the connection support 360 and to give way to the movement of the connection support 360, avoiding obstructing the movement of the connection support 360. The connection support 360 may pass through the first arc-shaped hole 122 and connect the rotating bracket 310 and the gear plate 210. When the gear plate 210 rotates, the gear plate 210, the connection support 360, and the rotation bracket 310 may all rotate around the axis of the first rotation shaft 320. In this embodiment, by providing the connection support 360, the connection strength between the rotating bracket 310 and the gear plate 210 can be enhanced, and the stability of the rotating bracket 310 can be improved. Furthermore, the connection support member 360 is disposed through the first arc-shaped hole 122, so when the rotating bracket 310 is subjected to an external force, the space interference between the hole wall of the first arc-shaped hole 122 and the connection support member 360 makes it difficult for the connection support member 360 to shift, so that the rotating bracket 310 cannot shift. In this manner, stability of the antenna assembly 300 may be improved.

In one embodiment of the present disclosure, the number of the first arc-shaped holes 122 is two and are disposed opposite to each other on both sides of the first rotation shaft. Further, the two connection supports 360 and the first rotation shaft 320 may be aligned in a straight line to further enhance the stability of the rotation bracket 310.

In one embodiment of the present disclosure, the first arcuate aperture 122 is located outside of the boss 121.

In one embodiment of the present disclosure, the connection support 360 is connected at one end to the gear wheel 210 and at the other end to the load-bearing bottom wall 311 of the rotating bracket.

In one embodiment of the present disclosure, the connection support 360 is a bolt, and the connection support 360 is detachably connected to the gear plate 210. Illustratively, the connection support 360 is a bolt having oppositely disposed nut and threaded ends. The bearing bottom wall 311 is provided with a through hole for penetrating the bolt; the bolt passes through the through hole, and the nut is positioned on the upper surface of the bearing bottom wall 311, so that the nut is abutted (pressed) on the bearing bottom wall 311; the threaded end passes through the first arcuate bore 122 and is threadably coupled to the gear plate 210. Wherein the extending direction of the bolt is parallel to the extending direction of the first rotation shaft 320.

In one embodiment of the present disclosure, the central angle corresponding to the first arc-shaped hole 122 is between 90 ° and 120 °.

Optionally, the rotating bracket 310 further comprises a support sidewall 312 connected to the load-bearing bottom wall 311. Further, the support sidewall 312 extends in a direction away from the base 100. Further, the supporting sidewall 312 is perpendicular to the bottom wall 311 and is disposed at an end of the bottom wall 311 in the extending direction. In one embodiment of the present disclosure, the number of the supporting side walls 312 is two, and the supporting side walls are respectively disposed at two ends of the bottom bearing wall 311. In this way, the rotating bracket 310 has a U-shape overall, and a receiving space is formed between the supporting sidewall 312 and the bearing bottom wall 311, and the receiving space can be used for receiving the antenna body 330.

In one embodiment of the present disclosure, referring to fig. 1-3, the antenna assembly 300 may further include a second rotation shaft 340 and a second angle adjustment assembly 350. The antenna body 330 is fixedly connected with the second rotating shaft 340, and the second rotating shaft 340 is rotatably connected with the supporting sidewall 312. The second angle adjusting component is used for fixing the second rotating shaft to the rotating bracket in an adjustable angle. The second angle adjustment assembly 350 is capable of controlling the relative state between the second rotation shaft 340 and the support sidewall 312 such that the second rotation shaft 340 is in a locked state or a rotatable state with respect to the support sidewall 312. When the second rotation shaft 340 is in a rotatable state, the antenna body 330 may be rotated in a circumferential direction of the second rotation shaft 340 to adjust a radiation angle range thereof. Further, the extending direction of the second rotation shaft 340 is perpendicular to the extending direction of the first rotation shaft 320. In this manner, the second angle adjustment assembly 350 can adjust the range of the elevation angle of the antenna body 330 when the mounting foot 140 is mounted on a horizontal mounting base surface. Thus, the spot light antenna in this embodiment can adjust the radiation angle range in two different dimensions.

Further, the number of the second rotating shafts 340 is two and located at both sides of the antenna body 330; the two second rotating shafts 340 are coaxially disposed and rotatably connected to the two supporting side walls 312, respectively. The number of the second angle adjusting members 350 is the same as that of the second rotating shafts 340, and is set in one-to-one correspondence. Wherein, the second angle adjusting assembly 350 includes a fastening member 352 and a fixed disk 351 connected to the corresponding second rotation shaft 340, and the fixed disk 351 is provided with a second arc-shaped hole 353 coaxial with the second rotation shaft 340. A fastener 352 (e.g., a bolt, screw, etc.) may be disposed through the second arcuate aperture 353 and secure the fixed disk 351 to the support sidewall 312. When the angle between the antenna body 330 and the rotating bracket 310 needs to be adjusted, the fastener 352 can be loosened, so that the fixed disk 351 and the supporting side wall 312 can relatively rotate, and further the antenna body 330 and the supporting side wall 312 can relatively move. When the antenna body 330 is adjusted to a desired angle, the fixing plate 351 can be fixed on the supporting sidewall 312 by using the fastening member 352, so that the angle between the antenna body 330 and the rotating bracket 310 is locked.

Alternatively, one end of the fastener 352 is detachably coupled to the support sidewall 312, and the other end has a protruding cap to press the fixing plate 351, thereby fixing the fixing plate 351 to the support sidewall 312. In one embodiment of the present disclosure, the fastener 352 may be a bolt, the threaded end of which may pass through the second arc-shaped hole 353 and be detachably coupled with the support sidewall 312 by screwing, and a nut (protruding cap) of the bolt abuts against the fixing plate 351 to fix the fixing plate 351 to the support sidewall 312. Still further, resilient gaskets may be provided between the fastener 352 and the fixed disk 351, particularly between the protruding cap of the fastener 352 and the fixed disk 351, to prevent the fastener from loosening.

Alternatively, the fixing plate 351 is disposed outside the support sidewall 312.

Further, at least one fixed disc 351 is provided with a plurality of second angle scales 354, and the plurality of second angle scales 354 are distributed in an arc shape with the axis of the second rotating shaft 340 as the center of a circle. The supporting side wall 312 is provided with a second indication mark 314 matched with a second angle scale 354, and the angle between the antenna body 330 and the supporting side wall 312 can be determined according to the scale value of the second angle scale 354 facing the second indication mark 314.

Alternatively, each second angle scale 354 is uniformly arranged in a circular arc shape with the axis of the second rotation shaft 340 as the center of a circle.

Alternatively, the second indication mark 314 may be an arrow, which may be disposed along the radial direction of the second rotation shaft 340.
