Description

M337067 VIII. New description: [New technical field] A pressure gauge, especially a pressure gauge that can be adjusted moderately in the highest and lowest pressure working range for a convenient and locked end of various liquid pipelines. Structural design. [Prior Art] There are several actuators available on the market that can be used to drive microswitches.

The structure of the pressure gauge, such as: electromagnetic switch, area switch, etc., the above-mentioned switch is mainly installed in various gas and liquid pipelines, by means of gas and liquid pressure pushing action, and then controlling The start or close of the micro switch is widely used in various j! industry applications, reducing unnecessary waste, and greatly improving the economic efficiency of the operator. The various pressure gauge structures that are common in the middle are still generally incapable of using a single pin to display the pressure under the highest and lowest working ranges.

Or the problem of 'when applied to various gas and liquid pipelines, in fact, J is unsuitable and as the operator accurately and quickly from the single-pointer for different pressures, the stability of the test is based on the basis of the test. Pass through a single pointer 3 . Although the structure can achieve the function of displaying the pressure, but no g is effectively controlled at the highest level m. Between the combination and the low pressure working range, the actual use of seven is not optimal. [New content] The "pressure gauge" provided by the creation of the dead is designed to provide a pressure gauge structure that is moderately adjusted in the range of the southernmost and lowest pressures in January, for the purpose of its main creation. M337067 * In order to achieve the above-mentioned creative purposes, the section used in this creation is for a "pressure gauge". The main spoon is the ribbed control unit and the upper cover, 2 = one body contact assembly, and a fixed hole at the bottom. ,?

Further, the peripheral edges of the first and second bumps 334 and 335 are formed with a plurality of missing portions 3342, 3352 and abutting edges 3343 and 3353, thereby forming the sensing sheets 33u1 and 3321 of the microswitches <3311/3391. In the contact state, the elastic tube of the top contact assembly 2〇 is expanded by the gas and liquid pressure, and the positioning piece 322 whose end is connected to the fixing block 22丨 is pulled to pull the first curved shape of the rotating rod 1 a portion 3212, and a rack 32111 of the first curved portion 2U opposite to the other end and a first gear 31312 of the first shaft 3131 are shaped to be connected to the first pointer 34, so that the first pointer 341 is The pressure data is displayed in the working range of the first pointer 342 of the highest β and the third pointer 343 of the lowest pressure. As shown in the figure of Le J, when the pressure gauge is actually used, the contact assembly 2 穿 of the micro-1 〇 socket 1 3 can be used, and the elastic tube 2 2 The pointer group 34 11 M337067 of the 221 upper locking control component 30 refers to whether the gas and liquid assembled by various gas and liquid pipelines (not shown) connected by the pressure gauge are met, and need to be used before the pressure gauge is used. Adjusting the highest and lowest pressures in their safe range, firstly, adjusting and pressing the shaft member 314 downward by the rotating lever 317 causes the gear 3141 to mesh with the first rack 3313 of the first moving piece 331 when the first rack At the same time as the rotation of the 3313, the second rack 3314 is sprayed with the third gear 31331 and moved synchronously, so that the second (four) 342 is limited to the highest pressure (as shown in Figures 5 and 6). The rod 317 moves the shaft member 314 downward again. Referring to Figures 5 and 7, the gear 3141 of the shaft member 314 and the first rack 3323 of the second moving piece 332 are engaged. While rotating the rack 3323, the second rack 3324 is also spliced and synchronously moved by the second gear 31321. The third pointer 343 is caused to be limited to the lowest pressure. When various gases and liquids (as indicated by the arrows in FIG. 8) can flow through the inlet port 211 of the stem 21 and expand by the pressure generated by the flow of the gas and the liquid in the elastic tube 22, and One end of the positioning piece 322 formed at the end fixing block 221 pulls the second curved portion 3212 of the rotation #321, and the opposite direction corresponds to the first M-shaped portion of the first curved portion 32m of the other end and the first axis #3131 - the gear 31312 forms a saliva transmission to the first pin 341 (as shown in Fig. 9), so that the first pointer 341 is in the working range of the second pointer 342 of the pressure and the third pointer (10) of the lowest power. Display its pressure data. In addition, when the pressure of the gas and the liquid continues to push and the elastic tube Μ again = the pulling distance is larger, the first pointer 341 indicates the first shaft 3131 when the second pointer 342 exceeds the highest limit pressure. a gear mu 12 M337067

r I ψ and the rack 32111 of the first curved portion 32H are also relatively rotated. When the rack 32111 of the rotating rod 321 is rotated, the top edge 3343 of the first cam 334 of the upper end of the shaft 3213 is also activated. The feeling of the top micro switch 3311 forms a contact and emits a signal, immediately notifying that the gas and hydraulic pressure are released, and letting the first pointer 341 indicate the work of the highest and lowest pressures. The pressure gradually becomes untimely, and the first pointer 341 is again referred to the outside of the pointer 343, so that the first gear 31312 of the first shaft 3131 and the rack 32111 of the curved portion 3211 are also relatively rotated, when the rotation rod is At the same time, the rack 32111 rotates, and also drives the top edge 3353 of the second cam 335 of the lower end of the shaft 3213 to activate the sensation of the micro switch 3321 = 33211, forming a contact and sending a signal, and immediately notifying to continue to make up. , the pressure of the liquid, and repeated delivery from the elastic tube 22 and again communicated • When the first gear 31312 of the control assembly 30 is rotated, the first pointer 341 that is coupled to the first shaft is displayed in the highest and lowest pressure working range ( Between the pressure data in Figure 10 and Figure 11) . _ [Simple description of the drawing] Figure 1: Top view of the creation (adding the cover) Figure 2 · Top view of the creation (without the cover) Figure 3: The exploded view of the contact assembly of the creation 4: The exploded view of the control component of this creation.
