[0028] As shown in Figure 1 Embodiments of the present application provide a gas bag insertion assembly 100, which is mainly used for quickly inserting a gas bag. The gas bag insertion assembly 100 comprises a mounting member 110 and a plurality of air guide members 120.
[0029] The mounting member 110 is used for mounting the air guide members 120, and the air guide members 120 are used for quickly inserting the gas bag.
[0030] In one embodiment, the mounting member 110 is provided with a plurality of first mounting grooves 1111, and the air guide member 120 comprises an air inlet nozzle 121 and a mounting plug 122, which are connected. The air guide member 120 is removably arranged in the first mounting groove 1111, and when the air guide member 120 is arranged in the first mounting groove 1111, the mounting plug 122 is embedded in the first mounting groove 1111, and the air inlet nozzle 121 is exposed from the first mounting groove 1111. By starting the first mounting groove 1111 on the mounting member 110, the mounting position of the air guide member 120 is fixed. During the installation process, only the mounting plug 122 needs to be embedded in the first mounting groove 1111, and there is no need to further adjust the fixed position of the air guide member 120, which simplifies the installation operation of the air guide member 120 and improves the installation efficiency of the air guide member 120.
[0031] The mounting plug 122 is installed in the first mounting groove 1111 by embedding, and the outer peripheral shape of the mounting plug 122 matches the outer peripheral shape of the first mounting groove 1111. The mounting plug 122 is removably arranged in the first mounting groove 1111 by clamping between the mounting plug 122 and the groove wall of the first mounting groove 1111, and after the mounting plug 122 is installed in the first mounting groove 1111, the position of the mounting plug 122 is fixed, and there is no need to further adjust the position of the mounting plug 122.
[0032] In some embodiments, the mounting plug 122 is provided with a through hole, and the air inlet nozzle 121 and the mounting plug 122 are in communication.
[0033] In use, the air inlet of the gas bag is connected with the air inlet nozzle 121, and the external gas source is in communication with the mounting plug 122. The gas of the external gas source is input into the gas bag through the mounting plug 122 and the air inlet nozzle 121, and the gas flow is guided to improve the sealing performance.
[0034] In some embodiments, the mounting member 110 comprises a housing 111 and a plurality of gas inlet connectors 112, a first mounting slot 1111 is arranged on the housing 111, one gas inlet connector 112 is arranged in one first mounting slot 1111, and the mounting plug 122 is clamped with the gas inlet connector 112.
[0035] As shown in Figure 1 and Figure 2 , the housing 111 is a hollow structure, the hollow housing 111 is used to accommodate the pipeline connected with the external gas source, or the hollow housing 111 is used to reduce the weight, so that the housing 111 is easily fixed on the gas analyzer. The housing 111 is in the shape of a rectangular parallelepiped, and it can be understood that the housing 111 can also be arranged in the shape of a cylinder, a circular truncated cone, etc., and the shape of the housing 111 can be arranged as required.
[0036] A plurality of first mounting slots 1111 are arranged on one side wall of the housing 111 (such as the side wall of the top of Figure 1 and Figure 2 ), and the first mounting slot 1111 penetrates the side wall, so as to facilitate the arrangement of the gas inlet connector 112 in the first mounting slot 1111 and the communication of the hose connected with the gas source with the gas inlet connector 112.
[0037] The gas inlet connector 112 and the mounting plug 122 are clamped. For example, the gas inlet connector 112 is clamped with the hole wall of the through hole of the mounting plug 122. Such clamping structure improves the sealing between the gas inlet connector 112 and the mounting plug 122, and also fixes the installation position of the mounting plug 122 and the gas inlet nozzle 121, so that the position of the mounting plug 122 does not need to be adjusted again, simplifies the installation operation of the gas guide member 120, and improves the installation efficiency of the gas guide member 120.
[0038] In some embodiments, the axis of the gas inlet nozzle 121, the axis of the through hole of the mounting plug 122 and the axis of the gas inlet connector 112 coincide.
[0039] As shown in Figure 1 and Figure 2 , the gas inlet nozzle 121 is generally in the shape of a cone, the mounting plug 122 and the first recess are in the shape of a rectangle in cross section, and the gas inlet connector 112 is in the shape of a circle in cross section. The coincidence of the axis of the gas inlet nozzle 121, the axis of the through hole of the mounting plug 122 and the axis of the gas inlet connector 112 can improve the concentricity of the gas inlet nozzle 121 and the gas inlet connector 112, make the gas flow more smoothly, and improve the gas inlet efficiency. At the same time, in the actual use process, the improvement of the concentricity can reduce the gas leakage and reduce the correction frequency of the position of the gas inlet nozzle 121 by the operator.
[0040] In some embodiments, the shell 111 is further provided with a second mounting groove 1112, and the first mounting groove 1111 is arranged at the groove bottom of the second mounting groove 1112. The gas bag plug-in assembly 100 further comprises a limiting piece 130 arranged in the second mounting groove 1112.
[0041] In order to reduce the falling of the air guide piece 120 from the first mounting groove 1111, the limiting piece 130 is arranged on the surface of the shell 111 to fix the plurality of air guide pieces 120 in the first mounting groove 1111, thereby reducing the falling.
[0042] As shown in Figure 1 and Figure 2 , the limiting piece 130 is in the form of a plate. The second groove is arranged on the upper surface of the shell 111, and the limiting piece 130 is arranged in the second groove and covers each mounting plug 122.
[0043] The matching precision of the air inlet nozzle 121 and the instrument panel air inlet nozzle 121 hole directly affects the working performance and sealing performance of the instrument. In the prior art, in order to realize the connection between the air inlet nozzle 121 and the instrument panel, a simple cylindrical matching structure is usually used. Under this structure, there is a large tolerance range between the air inlet nozzle 121 and the hole on the instrument panel, which can cause the two to be out of concentricity during installation.
[0044] Different concentricity not only affects the smoothness of gas flow, but also can cause poor sealing, thereby causing leakage and other problems. In addition, this design requires high assembly skills of the operator in actual application. If the assembly is not proper, the problem of different concentricity can be further aggravated, affecting the overall stability and reliability of the equipment.
[0045] In some embodiments, a plurality of limiting holes 131 are formed on the limiting piece 130, one limiting hole 131 is in communication with one first mounting groove 1111, when the air guide piece 120 is arranged in the first mounting groove 1111, the air inlet nozzle 121 is arranged in the limiting hole 131, and the axis of the limiting hole 131 and the axis of the air inlet nozzle 121 coincide.
[0046] As shown in Figure 1 and Figure 2 , by making the air inlet nozzle 121 outside and the limiting hole 131 form a transition fit, the position of the air inlet nozzle 121 and the position of the limiting piece 130 are fixed, and the assembly difficulty of the limiting piece 130 is reduced. The axis of the limiting hole 131 and the axis of the air inlet nozzle 121 coincide, the concentricity of the air inlet nozzle 121 and the limiting hole 131 is improved, the gas flow is smoother, and the gas conveying efficiency is improved. At the same time, in the actual use process, improving the concentricity can reduce gas leakage and the correction frequency of the operator to the position of the air inlet nozzle 121.
[0047] In some embodiments, the limiting member 130 is a circuit board.
[0048] By making the limiting member 130 a circuit board and integrating various electronic components 132 on the circuit board, the electronic components 132 are arranged on the side of the limiting member 130 facing the first mounting groove 1111, and the electronic components 132 are protected by being accommodated in the second mounting groove 1112, making the structure of the gas bag plug-in assembly 100 compact and making the gas bag plug-in assembly 100 more intelligent.
[0049] For example, the gas collecting process of the gas bag is as follows: the gas inlet of the gas bag is plugged with the gas inlet nozzle, the original gas in the gas bag is first discharged, the gas source valve is opened, the gas enters the gas bag, the inflation of the gas bag is observed, the valve is adjusted to ensure that the gas flow rate is moderate to avoid overpressure of the gas bag; after collecting enough gas, the gas source valve is closed, the connection between the gas bag and the gas source is disconnected to prevent gas leakage; the gas inlet valve of the gas bag is closed to ensure sealing.
[0050] In one embodiment, by electrically connecting the circuit board and the valve of the gas source, the opening, gas conveying time and closing of the gas source valve are controlled by the electronic components 132, which reduces the operation intensity of manual gas collection, especially in the case of simultaneous gas collection of multiple gas bags, the circuit board can assist manual operation to improve the efficiency of gas collection.
[0051] In some embodiments, the gas bag plug-in assembly 100 further comprises a fixing member arranged on the limiting member 130, the fixing member connects the limiting member 130 and the mounting member 110, and the connection between the limiting member 130 and the housing 111 is made more firm by arranging the fixing member.
[0052] In one embodiment, as shown in Figure 1 and Figure 2 The circumferential side of the limiting hole 131 is provided with a plurality of symmetrically arranged stacking holes 141, the stacking holes 141 are arranged on the limiting member 130 and the mounting plug 122, or the stacking holes 141 are arranged on the limiting member 130 and the housing 111, the number of fixing members is a plurality, and one fixing member is arranged in one stacking hole 141. For example, the fixing member is a screw, the stacking hole 141 is a threaded hole, and the limiting member 130 is fixed to the housing 111 by threaded connection, which is simple and efficient.
[0053] By arranging a plurality of symmetrically arranged stacking holes 141 on the circumferential side of the limiting hole 131, the connection between the limiting member 130 and the housing 111 is made more stable, and at the same time, the axial positions of the limiting hole 131 and the gas inlet nozzle 121 are positioned, improving the concentricity of the limiting hole 131 and the gas inlet nozzle 121.
