[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0027] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] One preferred embodiment of the present application, as shown in Figure 1 and Figure 2 A steel throat assembly for a pressure gauge, comprising a tank body 1, a steel throat 2, and a fastener; the fastener is installed on the outside of the tank body 1; the steel throat 2 is arranged between the fastener and the tank body 1, so that the steel throat 2 can be fixed to the outside of the tank body 1 by the fastener.

[0029] The advantage of the present scheme over the traditional scheme is that the present scheme can fix the originally suspended steel throat 2 to the outside of the nitrogen tank body 1 by the fastener, so that the steel throat 2 is not easily shaken and displaced during transportation, thereby improving the stability and safety of the overall device of the material hitting device.

[0030] For the setting of the fastener, in the embodiment, the fastener can be set as a clamp 3, and the fastener can also be set as a clasp; in the embodiment, as shown in Figure 2 and Figure 3 , the fastener is preferably a clamp 3; the clamp 3 is arranged on the outside of the tank body 1 to fix the steel throat 2; the specific structure of the clamp 3 is known to those skilled in the art, and therefore is not described here.

[0031] In order to facilitate understanding, the working process of the clamp 3 is described in detail below.

[0032] Initially, the clamp 3 is sleeved on the outside of the tank body 1, and the bolt 31 and the nut 310 on the clamp 3 are not tightened at this time; then the steel throat 2 is installed between the tank body 1 and the clamp 3, and at this time the steel throat 2 is not fixed by the clamp 3.

[0033] When it is necessary to fix the steel throat 2, as shown in Figure 3 , first tighten the nut 310; the nut 310 will drive the clamp 3 to exert force on the steel throat 2 during tightening, so that the steel throat 2 is fixed on the outside of the tank body 1.

[0034] It can be understood that the steel throat 2 is tubular and has a certain length, and if only one clamp 3 is arranged on the tank body 1, it can be understood that only one place on the outside of the steel throat 2 is under stress when the steel throat 2 is fixed on the outside of the tank body 1; the material loading device will vibrate during transportation, and if only one place on the steel throat 2 is under stress when the steel throat 2 reaches a certain length, it can cause unstable installation of the steel throat 2 during transportation.

[0035] Therefore, in the embodiment, as shown in Figure 1 and Figure 5 , there are multiple clamps 3, and the multiple clamps 3 are arranged at intervals along the axis of the tank body 1. It can be understood that the clamp 3 also needs to be fixed and limited on the tank body 1, and the multiple clamps 3 also need to be connected; therefore, one of the clamps 3 is used to be fixed and connected with the external body 4, and the adjacent clamps 3 are connected through a support structure.

[0036] For the above-mentioned support structure, there are multiple setting modes, and the specific structure of each mode is different; in the embodiment, a support rod 302 is arranged on one of the adjacent clamps 3, and the support rod 302 can be connected with the other clamp 3 through a limiting structure to form a support structure.

[0037] For the above-mentioned limiting structure, in order to facilitate understanding, two examples are described in detail below.

[0038] Example one: the limiting structure includes a connecting groove 3010 arranged on another hoop 3; the support rod 302 can be inserted into the connecting groove 3010 for interference fit or transition fit to form the limiting structure.

[0039] Specifically, one of the adjacent hoops 3 is provided with a support rod 302 extending along the axis direction of the hoop body 30; another hoop 3 of the adjacent hoops 3 is provided with a connecting groove 3010, and the support rod 302 is equivalent to being fixedly connected between the adjacent hoops 3 through the support rod 302 and the connecting groove 3010 after interference fit or transition fit in the connecting groove 3010, thereby forming the limiting structure.

[0040] Example two: the limiting structure includes a limiting hole 3020 arranged on the support rod 302, a connecting groove 3010 arranged on another hoop 3 of the adjacent hoops 3, and a pin 303; the limiting hole 3020 and the connecting groove 3010 are equal in position and size; the pin 303 can pass through the limiting hole 3020 and the connecting groove 3010 to limit the support rod 302.

[0041] It can be understood that when the pin 303 passes through the limiting hole 3020 and the connecting groove 3010, the support rod 302 and the other hoop 3 have been fixedly connected, thereby achieving fixed connection between the adjacent hoops 3.

[0042] Considering that the wall thickness of the hoop body 30 of the hoop 3 is not very thick and is not convenient to process, as shown in FIGS. 5 and Figure 6 The outer sides of the adjacent hoops 3 are each provided with a connecting block 301, the support rod 302 is arranged on the connecting block 301 on the outer side of one of the adjacent hoops 3, and the connecting block 301 on the outer side of the other hoop 3 is provided with a connecting groove 3010; the pin 303 is independently arranged in this embodiment, and there is a risk of loss after being pulled out of the connecting groove 3010 and the limiting hole 3020, so the connecting block 301 provided with the connecting groove 3010 is provided with a connecting hole 3011 on one side relative to the pin 303, an elastic member 3012 is arranged in the connecting hole 3011, the elastic member 3012 is connected with the pin 303, so that the pin 303 can be connected to the connecting block 301, so that the pin 303 will not be lost.

[0043] The elastic member 3012 can be variously arranged, and a spring is preferably adopted in this embodiment.

[0044] It should be known that the support rod 302 needs to be arranged with a certain length, so the limiting hole 3020 can be arranged with multiple limiting holes 3020, and the multiple limiting holes 3020 are arranged at intervals along the axis direction of the tank body 1; the arrangement of the multiple limiting holes 3020 can adjust the distance between the adjacent hoops 3 to adapt to tank bodies 1 of different heights.

[0045] It can be understood that the steel throat 2 is tubular, and the side of the clamp 3 fixed to the steel throat 2 is smooth without recess; if the clamp 3 is directly fixed to the steel throat 2, the steel throat 2 may shake along the inner wall of the clamp 3 during transportation. Therefore, in the embodiment, the clamp body 30 of the clamp 3 is provided with a recess 300; the clamp 3 can contact the outer side of the steel throat 2 through the recess 300 and limit the steel throat 2.

[0046] Specifically, as shown in Figure 3 , the clamp body 30 is provided with a recess 300, which can be attached to the outer side of the steel throat 2; the recess 300 can limit the movement of the steel throat 2 along the inner wall of the clamp 3, so that the steel throat 2 will not shake during transportation.

[0047] In the embodiment, a buffer 32 is arranged between the steel throat 2 and the clamp 3; the clamp 3 can contact the outer side of the steel throat 2 through the buffer 32, and the buffer 32 can limit the steel throat 2. The buffer 32 is provided with an inner recess 320 on the side close to the clamp 3; the clamp 3 can be embedded in the inner recess 320 and attached to the buffer 32, and the inner recess 320 can limit the clamp 3; the buffer 32 is a rubber ring.

[0048] Specifically, as shown in Figure 2 and Figure 4 , the buffer 32 is arranged between the steel throat 2 and the clamp 3, and the buffer 32 is a rubber ring in the embodiment; the clamp 3 will generate a force on the steel throat 2 when it is tightened to fix the steel throat 2; the rubber ring itself has a damping feeling, which can limit the movement of the steel throat 2 when it is forced to act on the steel throat 2; if the rubber ring is smooth on the side relative to the clamp 3, it may cause the clamp 3 to move; the arrangement of the inner recess 320 can make the clamp 3 embedded in the rubber ring; such arrangement can make the clamp 3 not move after installation.

[0049] The recess 300 and the buffer 32 described above can meet the needs of the embodiment; those skilled in the art can choose according to actual needs; the buffer 32 is preferred in the embodiment.

[0050] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments; the above embodiments and descriptions are only the principles of the present application; various changes and improvements can be made without departing from the spirit and scope of the present application; these changes and improvements all fall within the scope of the claimed present application. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
