Description

TECHNICAL FIELD

[0001] The utility model relates to video monitoring equipment technical field, concretely is a kind of monitoring vertical pole of different diameter assembly. BACKGROUND

[0002] At present, most of the different diameter assembly monitoring vertical pole, it is using internal and external thread combination connection structure at assembly connection, and top welding cover plate. For example, the utility model patent with patent No.202321368020.5, because it is the structure of different diameter assembly, in order to realize the connection of two section rod body of different diameter, the prior art adopts the way that the diameter of the top of lower section rod body is reduced to the same diameter with the bottom of upper section rod body, and internal and external threads of two section rod body are processed respectively to realize connection assembly;This way causes the top of lower section rod body to form step due to diameter reduction, and after vertical pole combination is completed, cable cannot pass through the step from the bottom of vertical pole to the lead-out position of side surface of vertical pole top, so cable needs to be assembled first through lower section vertical pole and then through upper section vertical pole to reach the lead-out position of top side surface, and then the internal and external thread structure of prior art needs to continuously rotate one end of rod body to realize screwing, which causes the internal cable to be continuously rotated with it in the process of screwing: the cable is easily damaged, especially in the winter low temperature of northern China, the cable skin is very brittle, continuous rotation can cause cable breakage, and once the cable is damaged, it is not easy to be found because it is inside the vertical pole, which can easily cause equipment operation hazard. In addition, the internal and external thread type connection structure has low installation efficiency, and one person needs to fix one section vertical pole during assembly, and another person or two people need to hold another section vertical pole to align and tighten, so single technical personnel is difficult to complete the assembly independently. CONTENT OF UTILITY MODEL

[0003] The utility model aims at providing a kind of different diameter assembly monitoring vertical pole to avoid the damage of cable in monitoring vertical pole due to continuous rotation, and can improve assembly efficiency to solve the above problems.

[0004] A kind of different diameter assembly monitoring vertical pole, including bottom flange, bottom flange is connected with the first vertical pole lower end by welding, the first vertical pole upper end is welded with upper end flange, the flange hole lower end of upper end flange is coaxially welded with welding nut, the second vertical pole lower end is welded with connection flange, connection flange lower end is connected with upper end flange by bolt, the diameter of second vertical pole is less than the diameter of first vertical pole, the second vertical pole is slidably connected with rain cover, rain cover can cover the connecting place of upper end flange and connection flange, the upper portion of second vertical pole is welded with quadrangular base, quadrangular base side surface is connected with outgoing line cross arm, bottom flange, first vertical pole, second vertical pole and outgoing line cross arm are internally communicated.

[0005] The utility model has the advantages of:

[0006] The assembling position of the assembled monitoring vertical pole is changed from the original threaded connection structure to the structure connected by the connecting flange and the upper end flange through bolt connection, which can prevent the cable from being damaged in the vertical pole and improve the installation efficiency.

[0011] With reference to the drawings, an assembled monitoring vertical pole with different diameters comprises a bottom flange 1, the bottom flange 1 is connected with a first vertical pole 2 through welding at the lower end, the upper end of the first vertical pole 2 is welded with an upper end flange 401, the flange hole of the upper end flange 401 is coaxially welded with a welded nut at the lower end, a second vertical pole 3 is welded with a connecting flange 501 at the lower end, the connecting flange 501 is connected with the upper end flange 401 through bolts at the lower end, the diameter of the second vertical pole 3 is smaller than that of the first vertical pole 2, the second vertical pole 3 is slidably connected with a rain cover 202, the rain cover 202 can cover the connecting position of the upper end flange 401 and the connecting flange 501, the upper part of the second vertical pole 3 is welded with a square base 302, the square base 302 is connected with an outgoing horizontal arm 301 at the side, and the bottom flange 1, the first vertical pole 2, the second vertical pole 3 and the outgoing horizontal arm 301 are internally communicated.

[0012] Specifically, the bolt is screwed with the nut after penetrating the flange hole of the connecting flange 501 and the flange hole of the upper end flange 401.

[0013] Specifically, the bottom flange 1 is provided with a wire hole penetrating the middle part.

[0014] Specifically, the rain cover 202 is a conical structure.

[0015] Working process and use principle of the utility model:

[0016] During the operation process, the operator leads the cable out to the leading position through the bottom flange 1, the first vertical pole 2, the connecting flange 501, the upper end flange 401 and the outgoing horizontal arm 301, and finally connects the connecting flange 501 with the upper end flange 401 through the bolt.

[0017] First, the cable (wire, optical fiber) passing through the device will not produce winding, winding here refers to spiral winding around itself, which can extend the service life of the wire, avoid its own winding cracking, at the same time, the optical fiber can not have any winding during threading, so that the service life of the optical fiber can be extended;

[0018] The cable inside the device is led from a distance, and the cable remains a distance at the device pre-buried place, which meets the requirement of cable passing through the whole stand and connecting with the monitoring device. The variable diameter stand in the prior art cannot solve the problem of cable winding;

[0019] The patent emphasizes that the stand is two pieces of rod with different diameters, which is to meet the market demand and reduce the overall weight and save the corresponding material cost.
