Abstract
The utility model discloses a kind of transmitter visor compressing structure, described compressing structure comprises transmitter protecgulum, wherein also comprises a pressure ring, described pressure ring and transmitter protecgulum threaded, is formed compress the visor in transmitter and display cover.This programme uses pressure ring to be spirally connected compression visor, thus makes the sealingly secure, reliably of visor and lid.
Description
Technical field
The utility model relates to the technical fields such as pressure unit, differential pressure transmitter, absolute pressure transmitter, is specifically related to the compressing structure of transmitter visor.
Background technology
The sealing means of mode for using stage clip to block draw-in groove compression visor is compressed at the transmitter protecgulum stage clip used in the past.
In this compressing structure, the reasons such as the size of draw-in groove and the quality problems of clip, the sealing of visor and display pressure ring is easily made not reach requirement, the particularly transmitter of explosion-proof type, cause loosening of visor, explosion-proof requirement can not be met, in use easily reveal, thus cause the explosion-proof of transmitter or waterproof, this inefficacy of gas-tight.
Utility model content
For the problem existing for existing transmitter visor compressing structure, the purpose of this utility model is to provide one that visor and display cover can be made to combine closely, and plays the mounting structure of positiver sealing.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of transmitter visor compressing structure, described compressing structure comprises transmitter protecgulum, and it also comprises a pressure ring, described pressure ring and transmitter protecgulum threaded, is formed compress the visor in transmitter and display cover.
Further, the arranged outside of described pressure ring has pin thread, and the inwall of transmitter protecgulum is provided with the female screw of corresponding matching.
Further, the through hole on described pressure ring is circular counter bore structure.
Be supplied to compressing structure by the utility model and can reach reliable sealing to transmitter visor, can differential pressure be practically applicable to, gauge pressure, the sealing of absolute pressure pressure unit, avoid transmitter to cause the shortcoming lost efficacy because of leakage.
Accompanying drawing explanation
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of transmitter in the utility model;
Fig. 2 is the front view of pressure ring in the utility model;
Fig. 3 is the cut-open view of pressure ring in the utility model;
Fig. 4 is compression schematic diagram of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, it is depicted as the structural representation of transmitter in this example.This transmitter comprises a housing 100, is provided with transmitter protecgulum 101, pressure ring 102 (shown in Fig. 2 and 3), visor 103, display cover (see Fig. 4).
Wherein, form compressing structure by threaded between transmitter protecgulum 101 and pressure ring 102 and visor 103 and display cover are compressed, visor and display cover are combined closely, reaches the effect of positiver sealing.
In order to realize and being spirally connected of pressure ring, the inwall of this transmitter protecgulum 101 is provided with female screw 101a.
See Fig. 2 and Fig. 3, its be structural representation for pressure ring in this example 102.This pressure ring entirety coordinates with the madial wall of transmitter protecgulum, and the through hole 102a on it is a circular counter bore structure, and coordinates with visor, display cover; Simultaneously radially symmetrically on the upper surface of pressure ring offer a pair notch 102b, so that visor, display cover coordinate, ensure press seal effect further.
In order to realize reliable and stable being spirally connected with transmitter protecgulum, the lateral wall of pressure ring is provided with pin thread, coordinates with it, and the madial wall of transmitter protecgulum is provided with corresponding female screw.
Thus, when compressing visor and display cover, both correspondences are arranged between pressure ring and transmitter protecgulum, transmitter protecgulum 101 is coordinated with the pin thread on pressure ring by the female screw on it, the threaded of both realizations, and compress pressure ring thus, then by pressure ring, visor is compressed, visor and display cover just can be made to combine closely (as shown in Figure 4), thus reach the effect of positiver sealing.
According to the pressing sealing structure that such scheme provides, visor and display cover can be made to combine closely, the positiver sealing of both realizations, effectively overcome deficiency of the prior art.And the requirement meeting working condition, production technology can be reached, visor is well fixed, meets explosion-proof, waterproof, the requirement of anti-gas,
More than show and describe ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
