[0002] Outdoor surveillance camera poles are pole brackets used to install outdoor surveillance camera equipment, collectively referred to as camera poles. Some camera poles do not have a lifting function and are only fixed in height, so their applicable usage scenarios are relatively limited. However, some camera poles have a lifting function, which is convenient for adjusting the height of the camera equipment to meet the camera needs of various scenes.

[0003] In the prior art, there are usually two specific lifting methods for camera poles with lifting functions: first, the pole body itself has a lifting function, and the position of the camera equipment is fixed after installation. When the camera equipment needs to be lifted or lowered, a large auxiliary vehicle or equipment such as a crane is required to complete the lifting of the pole body. Second, rollers are provided in conjunction with traction ropes to drive the camera equipment to achieve the lifting function. However, the above two lifting methods of the prior art will produce large shaking during the process of adjusting the height of the camera equipment for lifting and lowering. The violent shaking may have an adverse effect on the camera equipment and even cause damage to the camera equipment.

[0004] In order to solve the above technical problems, the present application provides an external guide rail lifting camera rod. Summary of the invention

[0023] In order to better understand the above technical solution, the exemplary embodiments of the present utility model will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more clear and thorough understanding of the present utility model and to convey the scope of the present utility model completely to those skilled in the art.

[0024] Embodiment:

[0025] The embodiment of the present utility model provides an outer rail type lifting camera rod, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, including: a rod body 1; a guide rail assembly provided on the side of the rod body 1; a pulley assembly 2 provided at the end of the guide rail assembly and connected to the inner wall of the rod body 1; a lifting assembly 3 passing through the guide rail assembly and connected to both the guide rail assembly and the pulley assembly 2; a positioning wheel assembly 4 provided inside the guide rail assembly, rollingly connected to the inner wall of the guide rail assembly and connected to the lifting assembly 3; a motor connecting piece 5 provided at the inner bottom end of the rod body 1 and connected to both the rod body 1 and the pulley assembly 2.

[0026] Exemplarily, a connection hole and a sealing plate are provided at the bottom end of the rod body 1 in this embodiment, and the motor connecting piece 5 is arranged inside the connection hole. When the outer rail type lifting camera rod needs to be lifted or lowered, the sealing plate is opened, and the motor connecting piece 5 is connected to an external motor, thereby providing power for the outer rail type lifting camera rod.

[0027] Exemplarily, the pulley assembly 2 in this embodiment is arranged at the upper and lower ends of the guide rail assembly. The pulley assembly 2 at the upper end plays a role in guiding and traction, and the pulley assembly 2 at the lower end plays a role in traction and wire winding. One end of the lifting assembly 3 is connected to the guide rail assembly, and the other end of the lifting assembly 3 is connected to the imaging device. The upper end of the lifting assembly 3 is connected to the upper end of the pulley assembly 2, and the lower end of the lifting assembly 3 is connected to the lower end of the pulley assembly 2. In this way, the imaging device follows the lifting assembly 3 and is tractioned by the pulley assembly 2 to realize lifting along the guide rail assembly. Moreover, at the outer bottom end of the rod body 1, it is connected to an external motor through a motor connector 5, and the motor provides power for the pulley assembly 2 through the motor connector 5, thereby realizing the lifting of the imaging device.

[0028] Exemplarily, the positioning wheel assembly 4 in this embodiment is slidably connected to the inner wall of the guide rail assembly. During the process of the lifting assembly 3 being tractioned by the pulley assembly 2 and lifting along the direction of the guide rail assembly, since the lifting assembly 3 passes through the guide rail assembly, the part of the lifting assembly 3 inside the guide rail assembly is fixedly connected to the positioning wheel assembly 4, and the part of the lifting assembly 3 outside the guide rail assembly is fixedly connected to the imaging device. With this setting, during the lifting process of the lifting assembly 3, through the rolling of the positioning wheel assembly 4, on the one hand, the friction between the lifting assembly 3 and the guide rail assembly is rolling friction, which greatly reduces the frictional resistance and makes the lifting of the lifting assembly 3 smoother, that is, the lifting of the imaging device is smoother; on the other hand, since the positioning wheel assembly 4 is rollingly connected to the inner wall of the guide rail assembly, the positioning wheel assembly 4 only rolls along the direction of the guide rail assembly relative to the guide rail assembly, which avoids the shaking of the lifting assembly 3 in other directions, and further avoids the violent shaking caused by the direct connection of the traction rope to the imaging device in the prior art, effectively improving the stability of the imaging device during the lifting process.

[0029] In a possible embodiment, as Figure 2 and Figure 3 shown, a buffer plate 6 is arranged above the guide rail assembly and is connected to the rod body 1; a positioning hole 7 is opened on the buffer plate 6; a buffer rod 8 is arranged above the lifting assembly 3 and corresponds to the position of the positioning hole 7; a buffer spring 9 is sleeved on the buffer rod 8 and is connected to the buffer rod 8.

[0030] Exemplarily, the rod body 1 in this embodiment is vertically arranged on the ground. Therefore, the buffer plate 6 is horizontally arranged. Two positioning holes 7 are opened on the buffer plate 6. Correspondingly, two positioning rods are arranged on the lifting assembly 3, and two buffer springs 9 are arranged on each positioning rod. With such a setting, during the rising process of the lifting assembly 3, the positioning rods accurately insert into the positioning holes 7. Due to the existence of the positioning springs, it fully plays a buffering role, ensuring that the imaging device can stably decelerate and stop when it reaches the top. In addition, since the positioning plate is horizontally arranged and two positioning rods are provided, when the positioning rods have been inserted into the positioning holes 7, the stability of the imaging device in the horizontal direction is further improved, and the shaking of the imaging device in the horizontal direction is reduced.

[0031] In a possible embodiment, as Figure 1 , Figure 3 and Figure 4 shown, a locking member 10 is arranged on the side wall of the lifting assembly 3 and is rotatably connected to the lifting assembly 3; a locking groove 11 is opened on the locking member 10; a locking tongue 12 is arranged on the outer wall of the guide rail assembly and is adapted to the locking groove 11.

[0032] Exemplarily, as Figure 1 shown, there are two locking members 10 in this embodiment, and the locking members 10 are controlled by a motor to rotate and can rotate clockwise and counterclockwise. They are arranged on both sides of the lower end of the lifting assembly 3, and correspondingly, two locking tongues 12 are fixedly connected to the side wall of the guide rail. Specifically, the locking tongue 12 is a rectangular plate, and the setting direction of the rectangular plate is obliquely upward towards the locking member 10. Correspondingly, the locking groove 11 is set to be obliquely downward towards the locking tongue 12, and the upper side length of the locking groove 11 is less than the lower side length of the locking groove 11. The locking member 10 rotates relative to the lifting assembly 3. With such a setting, during the rising process of the lifting assembly 3, the upper side of the locking groove 11 first contacts the rectangular plate. At this time, the motor controls the locking member 10 to rotate counterclockwise. After the rectangular plate enters the locking groove 11, the motor stops the locking member 10 from rotating, so that the locking member 10 and the locking tongue 12 are mutually engaged, thus preventing the lifting assembly 3 and the imaging device from falling, further increasing the stability of the lifting assembly 3 and the imaging device, and preventing the imaging device from falling.

[0033] In a possible embodiment, as Figure 1 and Figure 2 shown, the pulley assembly 2 includes: a first pulley 13, arranged above the guide rail assembly and connected to the rod body 1; a second pulley 14, arranged below the guide rail assembly and connected to the rod body 1; a steel wire rope 15, arranged between the first pulley 13 and the second pulley 14 and connected to the lifting assembly 3.

[0034] Exemplarily, the first pulley 13 in this embodiment is a fixed pulley, which is arranged above the guide rail assembly and connected to the lifting assembly 3 through a steel wire rope 15. That is, the first pulley 13 plays a role in guiding the direction, enabling the lifting assembly 3 to rise or fall along the arrangement direction of the guide rail assembly. The second pulley 14 is a winch, which is arranged below the guide rail assembly. The function of the winch is to wind the steel wire rope 15 to ensure that the steel wire rope 15 always maintains a fixed length during the lifting process of the lifting assembly 3, and the excess steel wire rope 15 can be wound on the winch. The number of winches can be set according to actual needs, and the number of winches is not limited here, that is, the number of the second pulley 14 is not limited.

[0035] In a possible embodiment, as Figure 2 shown, the guide rail assembly includes: a first side wall 16, which is arranged on the side surface of the rod body 1 and connected to the rod body 1; a first chute, which is opened on the first side wall 16; a second side wall 17, which is arranged on the side surface of the rod body 1 and symmetrically arranged with the first side wall 16; and a second chute, which is opened on the second side wall 17.

[0036] Exemplarily, the first side wall 16 and the second side wall 17 are symmetrically arranged on the side surface of the rod body 1. That is, the first side wall 16, the side surface of the rod body 1, and the second side wall 17 enclose three surfaces of the guide rail assembly. A first chute is arranged on the inner wall of the first side wall 16, and a second chute is arranged on the inner wall of the second side wall 17. The first chute and the second chute are also symmetrically arranged, thereby obtaining the guide rail assembly. And a sliding groove is also opened on the side surface of the rod body 1 where the first side wall 16 and the second side wall 17 are arranged. The length of the sliding groove is the same as the length of the first side wall 16 and the length of the second side wall 17. When the external guide rail type lifting camera rod in this embodiment is installed, the lifting assembly 3 penetrates into the rod body 1 from the lower end of the rod body 1 through this sliding groove. With this setting, the lifting assembly 3 is arranged to penetrate through the guide rail assembly and slide up and down along the guide rail assembly.

[0037] In a possible embodiment, as Figure 1 shown, the lifting assembly 3 includes: a frame body 18, which is arranged between the first side wall 16 and the second side wall 17 and connected to the steel wire rope 15; and a mounting rod 19, which is arranged on the side surface of the frame body 18 and connected to the frame body 18.

[0038] Exemplarily, in this embodiment, the frame body 18 and the mounting rod 19 are fixedly connected by bolts. The mounting rod 19 is arranged on the side surface of the frame body 18, and the mounting rod 19 is used to mount the camera device. With this setting, when the steel wire rope 15 drives the frame body 18 to move up and down, the frame body 18 drives the mounting rod 19 to move up and down, thereby realizing the up and down movement of the camera device.

[0039] In a possible embodiment, as Figure 1As shown, the positioning wheel assembly 4 includes: a first positioning wheel 20 disposed inside the first chute and the second chute and connected to the frame 18; a second positioning wheel 21 disposed between the first side wall 16 and the second side wall 17, and the diameter of the second positioning wheel 21 is equal to the width of the first side wall 16; the setting direction of the second positioning wheel 21 is perpendicular to the setting direction of the first positioning wheel 20.

[0040] Exemplarily, as Figure 1 shown, in this embodiment, the setting direction of the first positioning wheel 20 is perpendicular to the first side wall 16, and the first side wall 16 is parallel to the second side wall 17, that is, the first positioning wheel 20 is also perpendicular to the second side wall 17. Both ends of the first positioning wheel 20 are respectively in the first chute and the second chute, and the frame 18 is fixedly connected to the first positioning wheel 20. After such a setting, since both ends of the first positioning wheel 20 are limited, that is, one end is limited by the first chute and the other end is limited by the second chute, so during the process of the frame 18 being hoisted by the steel wire rope 15, in the setting direction of the first positioning wheel 20, no shaking can occur, thereby avoiding the shaking of the imaging device in this direction.

[0041] Exemplarily, as Figure 1 shown, the setting direction of the second positioning wheel 21 is perpendicular to the setting direction of the first positioning wheel 20. In this embodiment, the setting direction of the second positioning wheel 21 is parallel to the first side wall 16, that is, the second positioning wheel 21 is also parallel to the second side wall 17. And since the diameter of the second positioning wheel 21 is equal to the width of the first side wall 16, both ends of the second positioning wheel 21 are limited by the inner wall surface of the first side wall 16. So during the process of the frame 18 being hoisted by the steel wire rope 15, in the setting direction of the second positioning wheel 21, no shaking can occur, thereby avoiding the shaking of the imaging device in this direction.

[0042] In a possible embodiment, as Figure 1 shown, the number of the first positioning wheels 20 is multiple

[0043] Exemplarily, in this embodiment, two first positioning wheels 20 are provided and are respectively fixedly connected to the upper and lower ends of the frame 18, further improving the stability of the frame 18.

[0044] Specifically, the number of the first positioning wheels 20 can be set according to the length of the frame 18, and the number of the first positioning wheels 20 is not specifically limited here.

[0045] In a possible embodiment, as Figure 1 shown, the number of the second positioning wheels 21 is multiple.

[0046] Exemplarily, in this embodiment, the number of the second positioning wheels 21 is four. The two second positioning wheels 21 at the upper end are arranged on both sides of the first positioning wheel 20 on the frame body 18. One of the second positioning wheels 21 is limited by the first side wall 16. Since the first side wall 16 and the second side wall 17 are symmetrically arranged, the sizes of the first side wall 16 and the second side wall 17 are the same. Then the other second positioning wheel 21 is limited by the second side wall 17. In this way, the stability of the frame body 18 in the setting direction of the second positioning wheels 21 is further increased. The two second positioning wheels 21 at the lower end are arranged on both sides of the first positioning wheel 20 under the frame body 18, thereby increasing the stability of the frame body 18 during the lifting process and effectively avoiding the shaking of the imaging device in the setting direction of the second positioning wheels 21.

[0047] Specifically, the number of the second positioning wheels 21 can be set according to the length of the frame body 18, and the number of the second positioning wheels 21 is not specifically limited herein.
