Abstract
The utility model relates to the technical field of an instrument and especially relates to a waterproof conjunction box. The waterproof conjunction box comprises a box body. A box cover is connected to the top of the box body in a threaded manner. A wire passing port is arranged on the right end of the box body, and a wire passing bolt is in threaded connection with the inner wall of the wire passing port. The waterproof conjunction box also comprises an outer tapered sealing ring and an inner tapered sealing ring. The outer tapered sealing ring is tightly embedded on the inner wall of the wire passing port, and the outer tapered angle of the outer tapered sealing ring is 10 to 15 degrees. The inner tapered sealing ring is tightly embedded on the inner wall of the top of the box body, and the inner tapered angle of the inner tapered sealing ring is 13 to 18 degrees. When the waterproof conjunction box is used, the box body is sealed by the inner tapered sealing ring and the outer tapered sealing ring to prevent outer liquid from splashing into the box body to damage a thermal resistor, such that the service life of the thermal resistor can be prolonged. The waterproof conjunction box has the advantages of a simple structure, reasonable arrangement, low manufacturing cost or the like.
Description
Technical field
The utility model relates to field of instrumentation technology, particularly a kind of water-proof type terminal box.
Background technology
Thermal resistance is the most frequently used a kind of Temperature Detector of middle low-temperature space, and its principal feature is that measuring accuracy is high, stable performance.Wherein the measuring accuracy of platinum resistance thermometer sensor, is the highest, and it not only is widely used in industrial thermometric, and is made into the station meter of standard.Because the site environment of industry is poor, so thermal resistance need be placed in terminal box, thereby the protection thermal resistance is not damaged by foreign object.But the sealing property of popular terminal box is all poor in the market, so just easily affects the serviceable life of thermal resistance.
Therefore be necessary existing junction box structure is carried out technical renovation further.
The utility model content
The purpose of this utility model is for the defective of prior art and deficiency, and water-proof type terminal box a kind of simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of water-proof type terminal box described in the utility model, comprise box body, the top of the described box body lid that has been threaded, the right-hand member of described box body is provided with threading opening, the threading bolt has been threaded on described threading opening inwall, it also comprises male-tapered O-ring seal and inner conical O-ring seal, described male-tapered O-ring seal closely is nested on the threading opening inwall, the outside cone angle of male-tapered O-ring seal is 10～15 degree, described inner conical O-ring seal closely is nested on the top inwall of box body, and the interior cone angle of inner conical O-ring seal is 13～18 degree.
Further, the outside cone angle of described male-tapered O-ring seal is 12 degree.
Further, the interior cone angle of described inner conical O-ring seal is 15 degree.
after adopting said structure, the utility model beneficial effect is: a kind of water-proof type terminal box described in the utility model, comprise box body, the top of the described box body lid that has been threaded, the right-hand member of described box body is provided with threading opening, the threading bolt has been threaded on described threading opening inwall, it also comprises male-tapered O-ring seal and inner conical O-ring seal, described male-tapered O-ring seal closely is nested on the threading opening inwall, the outside cone angle of male-tapered O-ring seal is 10～15 degree, described inner conical O-ring seal closely is nested on the top inwall of box body, the interior cone angle of inner conical O-ring seal is 13～18 degree.When using the utility model, by inside and outside conical seal ring sealing box body, effectively avoided outside liquid Fei Splash to damage thermal resistance to box body inside, thereby can extend the serviceable life of thermal resistance.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.
Description of drawings
Accompanying drawing described herein is to be used to provide further understanding of the present utility model, consists of the application's a part, but does not consist of to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is structural representation of the present utility model;
Description of reference numerals:
1, box body; 2, threading opening; 3, threading bolt; 4, male-tapered O-ring seal; 5, lid;

Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples wherein and explanation only are used for explaining the utility model, but not as to restriction of the present utility model.
as shown in Figure 1, a kind of water-proof type terminal box described in the utility model, comprise box body 1, the top of described box body 1 lid 5 that has been threaded, the right-hand member of described box body 1 is provided with threading opening 2, threading bolt 3 has been threaded on described threading opening 2 inwalls, it also comprises male-tapered O-ring seal 4 and inner conical O-ring seal 6, described male-tapered O-ring seal 4 closely is nested on threading opening 2 inwalls, the outside cone angle α of male-tapered O-ring seal 4 is 10～15 degree, described inner conical O-ring seal 6 closely is nested on the top inwall of box body 1, the interior cone angle beta of inner conical O-ring seal 6 is 13～18 degree.Can effectively avoid like this outside liquid Fei Splash to damage thermal resistance to box body inside, thereby can extend the serviceable life of thermal resistance.
As a kind of optimal way of the present utility model, the outside cone angle α of described male-tapered O-ring seal 4 is 12 degree.
As a kind of optimal way of the present utility model, the interior cone angle beta of described inner conical O-ring seal 6 is 15 degree.
During with the utility model installing thermal resistance, can effectively avoid outside liquid Fei Splash to damage thermal resistance to box body inside, thereby can extend the serviceable life of thermal resistance.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
