A rain hat as shown in fig. 1-5, comprising: the hoop assembly 10, the rain cover 20 connected with the hoop assembly 10, and the elastic wire mesh 30 arranged on the rain cover 20; the elastic wire mesh 30 and the hoop component 10 are located on the same side of the rain cover 20, and the elastic wire mesh 30 is a wavy elastic wire mesh 30 or a zigzag elastic wire mesh 30. In this embodiment, the elastic silk screen 30 is in a zigzag shape like a paper fan. In other embodiments, it may be wavy.
The rain-proof cap of this embodiment can be applicable to new and old owner and become, and need not dismantle any flange bolt, and the installation is simple, and is firm, can be applied to the rain-proof demand of multiple equipment such as body gas, pressure regulating gas, oil level gaugember, manometer, has higher commonality, elegant appearance to the effect of preventing the bird from nesting has. Specifically, when the rain hat of this embodiment is installed, the hoop assembly 10 and the oil pipe 50 provided with the relay 40 are fixed in an encircling manner, the rain cover 20 covers the relay 40, and the elastic wire mesh 30 is arranged on the rain cover 20, so that the elastic wire mesh 30 can fill the gap between the relay 40 and the rain cover 20, prevent birds from nesting, and the elastic wire mesh 30 elastically stretches up and down, left and right when contacting the relay, so that the installation of the rain hat of this embodiment is not affected. In addition, the hoop assembly 10 is fixed on the oil pipe 50, so that the installation and the disassembly are convenient.
The rain cover 20 is a stainless steel rain cover and the elastic wire mesh 30 is a stainless steel elastic wire mesh 30. Since the main function of the rain cover 20 is rain prevention, stainless steel materials are adopted for water prevention and rust prevention.
This embodiment elastic wire net 30 is located under rain-proof cover 20, just elastic wire net 30 covers the whole wall of rain-proof cover 20 below avoids leaving the clearance and builds the nest for birds. Namely, the length and the width of the elastic silk screen are respectively matched with the length and the width of the wall surface below the rain cover.
In order to ensure the elastic expansion effect of the elastic silk screen 30, two opposite side edges of the elastic silk screen 30 are welded to the rain-proof cover 20, and the middle part of the elastic silk screen 30 is not specially fixed.
The hoop component 10 comprises a hoop base 11, a hoop upper cover 12 and a fastening bolt 13, wherein the hoop base 11 is matched with the hoop base 11 to be clamped tightly, the fastening bolt 13 is used for fixing the hoop base 11 and the hoop upper cover 12, and the hoop upper cover 12 is connected with the rain cover 20. The oil pipe 50 is surrounded by the hoop base 11 and the hoop upper cover 12 and is screwed by the fastening bolt 13.
As shown in fig. 3, the hoop base 11 and the hoop upper cover 12 are both plates with arc grooves, the arc grooves of the hoop base 11 and the arc grooves of the hoop upper cover 12 have the same arc radius R, and the arc length L corresponding to the arc grooves of the hoop base 11 is the same as the arc radius R of the arc grooves of the hoop upper cover 121The arc length L corresponding to the arc groove of the hoop upper cover 122The sum is less than the circumference 2 pi R corresponding to the arc radius R. Namely, when the anchor ear base 11 and the anchor ear upper cover 12 are spliced, the splicing surfaces of the arc-shaped grooves are splicedAnd not a complete circle, thereby allowing a clamping margin for the hoop assembly 10. On the contrary, when the arc-shaped grooves of the hoop base 11 and the hoop upper cover 12 are both semicircles, and the force of the fastening bolt 12 basically acts on the contact surfaces of the hoop base 11 and the hoop upper cover 12 instead of the contact surfaces of the hoop assembly 10 and the oil pipe 50, so that the fastening effect of the hoop assembly 10 and the oil pipe 50 cannot be ensured.
Specifically, the arc length L corresponding to the arc groove of the hoop upper cover 12 in this embodiment is the arc length L2Is pi R, the arc length L corresponding to the arc-shaped groove of the hoop base 111Less than pi R. In other embodiments, other combinations are possible.
The rain cover 20 is connected with the hoop component 10 through a support rod 60; the hoop component 10 is provided with an insertion hole for the support rod 60 to penetrate through, a first end of the support rod 60 penetrates through the insertion hole of the hoop component 10, and a second end of the support rod 60 is fixedly connected with the rain cover 20; the second end of the support rod 60 is the end opposite to the first end. The number of the support rods 60 is two, and the two support rods 60 are arranged at the edge of the rain cover 20 at intervals, so that the hoop component 10 is arranged at one side edge of the rain cover 20, and the installation of the embodiment is facilitated.
The support rod 60 of this embodiment also has the effect of adjusting the height of the rain cover 20, so that the elastic wire mesh 30 is better contacted with the relay 40, and a gap is prevented from being generated between the elastic wire mesh 30 and the relay 40.
