[0053] In the embodiment, the gas fire extinguishing system intelligent pressure gauge further comprises a first connecting head 200, a connecting sleeve 300, a second connecting head 400, and a locking assembly.

[0054] The first section of the first connecting head 200 is fixedly connected with the gauge head 100, and the second end thereof is freely extended. The connecting sleeve 300 is coaxially sleeved on the second end of the first connecting head 200, and the connecting sleeve 300 is rotationally connected with the connecting sleeve 300, so that the first connecting head 200 and the connecting sleeve 300 can rotate relative to each other, thereby enabling the gauge head 100 to rotate around the axis of the connecting sleeve 300. The first end of the second connecting head 400 is coaxially inserted into the connecting sleeve 300, and the second end thereof extends away from the gauge head 100. The second connecting head 400 is fixedly connected with the connecting sleeve 300.

[0055] The locking assembly is arranged on the first connecting head 200 and / or the connecting sleeve 300. The locking assembly has a locking state and an unlocking state which can be switched with each other. When the locking assembly is in the locking state, the locking assembly locks the first connecting head 200, so that the first connecting head 200 cannot rotate relative to the connecting sleeve 300 or the first connecting head 200 can rotate relative to the connecting sleeve 300 only when the torque applied to the first connecting head 200 exceeds a preset value. When the locking assembly is in the unlocking state, the locking assembly releases the locking of the first connecting head 200, so that the first connecting head 200 can rotate relative to the connecting sleeve 300.

[0056] In use, when the dial head 100 needs to be rotated, the locking assembly is first switched to the unlocked state, so that the locking assembly releases the locking of the first connecting head 200, so that the first connecting head 200 and the connecting sleeve 300 can be relatively rotated; then the dial head 100 is rotated, and when the dial head 100 is rotated to a target position, the locking assembly is switched from the unlocked state to the locked state, so that the dial head 100 is conveniently adjusted.

[0057] Preferably, the second end of the second connecting head 400 is provided with external threads, so as to facilitate the installation and disassembly of the pressure gauge.

[0058] As shown in the embodiment, the locking assembly includes a locking disc 511 and an elastic element 512. Figures 1-8

[0059] The locking disc 511 is coaxially sleeved on the first connecting head 200, and the locking disc 511 is in sliding connection with the first connecting head 200, so that the locking disc 511 can only move along the axial direction of the first connecting head 200. The locking disc 511 has a locking position and an unlocking position which can be switched with each other. The elastic element 512 is sleeved on the first connecting head 200, and the two ends of the elastic element 512 are connected with the locking disc 511 and the dial head 100 respectively. In the natural state, the elastic element 512 exerts a spring force on the locking disc 511, so that the locking disc 511 has a tendency to move from the unlocking position to the locking position.

[0060] Among them, the opposite sides of the locking disc 511 and the connecting sleeve 300 are respectively provided with first locking tooth structures and second locking tooth structures which can be engaged.

[0061] When the locking disc 511 is in the locking position, the first locking tooth structure and the second locking tooth structure are engaged, and under the cooperation of the first locking tooth structure and the second locking tooth structure, the dial head 100 is locked.

[0062] When the locking disc 511 is in the unlocking position, the first locking tooth structure and the second locking tooth structure are away from each other, so that the dial head 100 can rotate around the axial line of the second connecting head 400.

[0063] When unlocking, the locking disc 511 is placed in the unlocking position, so that the first locking tooth structure and the second locking tooth structure are away from each other, and the first locking tooth structure and the second locking tooth structure cannot be engaged with each other, so that the dial head 100 can rotate around the axial line of the second connecting head 400.

[0064] ​When locked, the locking disc 511 is placed in the locking position, and the locking disc 511 is kept in the locking position under the action of the elasticity of the elastic element 512, so that the first locking tooth structure and the second locking tooth structure are engaged, and the first locking tooth structure and the second locking tooth structure are matched, so as to achieve the purpose of locking the watch head 100.

[0065] Specifically, the elastic element 512 is an element capable of exerting elasticity on the locking disc 511, such as an air spring, a hydraulic spring, a rubber spring, a spring, etc. In this embodiment, the elastic element 512 is a spring, which is simple in structure and low in cost.

[0066] As shown in Figures 1-8 , the first locking tooth structure and the second locking tooth structure are one-way guide tooth structures or two-way guide tooth structures.

[0067] As shown in Figures 1-4 , the one-way guide tooth structure includes a plurality of uniformly distributed one-way guide teeth, and the one-way guide tooth includes a stop surface and a guide surface.

[0068] In the natural state, the locking disc 511 is kept in the locking position under the action of the elasticity of the elastic element 512, and the first locking tooth structure and the second locking tooth structure are matched, so as to achieve the purpose of locking the watch head 100.

[0069] When the torque in the positive direction applied to the locking disc 511 exceeds the preset value, the locking disc 511 is subjected to a force under the action of the guide surface, so that the locking disc 511 moves from the locking position to the unlocking position against the elasticity of the elastic element 512.

[0070] When the torque applied to the locking disc 511 is in the reverse direction, the locking disc 511 cannot rotate under the action of the stop surface, so that the watch head 100 cannot rotate.

[0071] As shown in Figures 5-8 , the two-way guide tooth structure includes a plurality of uniformly distributed two-way guide teeth, and the two-way guide tooth includes two symmetrically arranged guide surfaces.

[0072] In the natural state, the locking disc 511 is kept in the locking position under the action of the elasticity of the elastic element 512, and the first locking tooth structure and the second locking tooth structure are matched, so as to achieve the purpose of locking the watch head 100.

[0073] When the torque applied to the locking disc 511 exceeds the preset value, the locking disc 511 is subjected to a force under the action of the guide surface, so that the locking disc 511 moves from the locking position to the unlocking position against the elasticity of the elastic element 512.

[0074] In the embodiment, the first locking tooth structure and the second locking tooth structure are set as one-way guiding tooth structure or two-way guiding tooth structure, so that when the torque applied on the dial head 100 or the locking disc 511 exceeds the preset value, the dial head 100 can be rotated, which is simple in structure and convenient to operate.

[0075] As shown in Figures 9-10 In the embodiment, the locking assembly includes a locking element 520 arranged on the outer sidewall of the connecting sleeve 300, and the locking element 520 extends along the radial direction of the connecting sleeve 300 and is threadedly connected with the connecting sleeve 300.

[0076] When locking, the locking element 520 is tightened to abut against the sidewall of the first connecting head 200. Specifically, when locking, the locking element 520 is tightened to move towards the axial line of the connecting sleeve 300, so that the locking element 520 abuts against the sidewall of the first connecting head 200 and is locked by the friction force between the locking element 520 and the sidewall of the first connecting head 200.

[0077] When unlocking, the locking element 520 is loosened to separate the locking element 520 from the sidewall of the connecting sleeve 300. Specifically, when unlocking, the locking element 520 is loosened to move away from the axial line of the connecting sleeve 300, so that the locking element 520 separates from the sidewall of the first connecting head 200, thereby achieving the purpose of unlocking the first connecting head 200.

[0078] The locking assembly in the embodiment is simple in structure and reasonable in design, and only needs to tighten or loosen the locking element 520 to achieve the purpose of locking or unlocking the first connecting head 200, which is simple to operate.

[0079] Specifically, in the embodiment, the locking element 520 is a screw fastener, i.e., a fastener with external threads on the circumferential wall, such as a locking bolt or a locking screw.

[0080] As shown in Figure 4 、 8 , 10, in the embodiment, the opposite ends of the first connecting head 200 and the second connecting head 400 are respectively provided with a groove 410 and a protrusion 210 matched with the groove 410. In operation, the groove 410 and the protrusion 210 are matched with each other to improve the sealing performance between the first connecting head 200 and the second connecting head 400.

[0081] Preferably, a sealing ring 600 is arranged in the groove 410 to improve the sealing between the first connector 200 and the second connector 400.

[0082] In the description of the present application, a large number of specific details are explained. However, it can be understood that the embodiments of the present application can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail in order not to obscure the understanding of the present application.

[0083] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the description of the present application.
