Abstract
The utility model discloses the pins under a kind of operating condition for high temperature corrosion, including pin cap, pin rod and convex body, the bottom of the pin cap is fixedly connected with pin rod, and the pin rod bottom is fixedly connected with convex body, the center of the pin rod offers open slot, and open slot is downward through in convex body；The pin rod is sequentially passed through in the first steel plate and the second steel plate, and the second steel plate and the convex body connect；This pin being used under high temperature corrosion operating condition is made using PTFE material, corrosion-and high-temp-resistant, particularly suitable for the connection under high-temperature concentrated sulfuric acid production status between acid trap acid distributing tube and F4 casing, it can prevent from falling off, energy corrosion-resistant and high-temperature resistant again, the Guan Yuguan being widely used under all other systems high temperature corrosion operating conditions, the connection occasion between plate and plate.
Description
Technical field
Pin the utility model relates to fastenings technical field, under specially a kind of operating condition for high temperature corrosion.
Background technique
Pin is a kind of common one of fastenings, its structure is simple, easy to use, is widely used between two parts
Connection and relative position fixation, can both prevent falling off or certain load capable of being transmitted for part, but currently used for spy
The pin of different operating condition be difficult to buy in the market or almost without.
Utility model content
The purpose of this utility model is to provide the pins under a kind of operating condition for high temperature corrosion, use PTFE material system
Make, corrosion-and high-temp-resistant, particularly suitable for the company under high-temperature concentrated sulfuric acid production status between acid trap acid distributing tube and F4 casing
Connect, can prevent from falling off and corrosion-resistant and high-temperature resistant, thus be widely used in high temperature corrosion operating condition down tube and pipe, plate and plate it
Between connection occasion, solve the problems of the prior art.
To achieve the above object, the utility model provides the following technical solutions：
A kind of pin under the operating condition for high temperature corrosion, including pin cap, pin rod and convex body, the bottom of the pin cap is fixed to be connected
Be connected to pin rod, the pin rod bottom is fixedly connected with convex body, and the center of the pin rod offers open slot, open slot downward through
In convex body；The pin rod is sequentially passed through in the first steel plate and the second steel plate, and the second steel plate and the convex body connect.
Preferably, the groove that the open slot among the pin rod is process by pin body.
Preferably, the pin cap, pin rod and convex body are made of PTFE material.
Preferably, the outside diameter of the convex body is greater than the diameter of pin rod.
Preferably, the pin cap, pin rod and convex body are coaxially set.
Compared with prior art, the beneficial effects of the utility model are as follows：
This is for the pin under high temperature corrosion operating condition, the groove that the open slot among pin rod is process by pin body,
Convex body is also directly process by ontology, and outside diameter is greater than pin rod diameter, and end is equipped with open slot, and main function is to make
With facilitating pin to squeeze into pin hole in the process, when pin squeezes into pin hole, face phase where convex body is convenient for pin hole relative to the plane of pin cap
It contradicts, by the extruding of pin hole and pin rod, pin just can not fall off, and be widely used under all other systems high temperature corrosion operating conditions
Guan Yuguan, the connection occasion between plate and plate.
Detailed description of the invention
Fig. 1 is the overall structure figure of the utility model.
In figure：1 pin cap, 2 pin rods, 3 convex bodys, 4 open slots, 5 first steel plates, 6 second steel plates.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the pin under a kind of operating condition for high temperature corrosion, including pin cap 1, pin rod 2 and convex body 3, pin cap 1,
Pin rod 2 and convex body 3 are made of PTFE material, and the bottom of pin cap 1 is fixedly connected with pin rod 2, and the bottom of pin rod 2 is fixedly connected convex
Body 3, pin cap 1, pin rod 2 and convex body 3 are coaxially set, the groove that the open slot 4 among pin rod 2 is process by pin body,
Convex body 3 is also directly process by ontology, and the outside diameter of convex body 3 be greater than pin rod 2 diameter, by pin rod 2 and convex body 3 come
Fixing pin and pin hole, the center of pin rod 2 offer open slot 4, and open slot 4 is downward through in convex body 3；Pin rod 2 sequentially passes through
In the first steel plate 5 and the second steel plate 6, the second steel plate 6 and convex body 3 are connected, and one end of the first steel plate 5 and the second steel plate 6 is opened
Pin is facilitated to squeeze into pin hole by open slot 4 equipped with pin hole, when pin squeezes into pin hole, plane of the convex body 3 relative to pin cap 1
Inconsistent convenient for face where pin hole, by the extruding of pin hole and pin rod 2, pin just can not fall off, thus by the first steel plate 5 and the
The connection of two steel plates 6.
This is process recessed for the pin under high temperature corrosion operating condition, the open slot 4 of 2 centre of pin rod by pin body
Slot, convex body 3 are also directly to be process by ontology, and 3 outside diameter of convex body is greater than 2 diameter of pin rod, and end is equipped with open slot
4, facilitate pin to squeeze into pin hole in use by open slot 4, when pin squeezes into pin hole, convex body 3 is relative to the flat of pin cap 1
Face is just inconsistent with face where pin hole, and by the extruding of pin hole and pin rod 2, pin just can not fall off, thus by 5 He of the first steel plate
The connection of second steel plate 6, thus the Guan Yuguan being widely used under all other systems high temperature corrosion operating conditions, the company between plate and plate
Connect occasion.
In summary：This is used for the pin under high temperature corrosion operating condition, structurally reasonable, at low cost, is made using PTFE material,
Corrosion-and high-temp-resistant, particularly suitable for the connection under high-temperature concentrated sulfuric acid production status between acid trap acid distributing tube and F4 casing,
It can prevent from falling off and corrosion-resistant and high-temperature resistant, thus effective solution the problems of the prior art.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
