[0046] When the gas meter enters the constant temperature factory, the temperature of the gas meter is different from the environment in the constant temperature factory. Therefore, the gas meter needs to be heated or cooled so that the temperature difference between the gas meter and the temperature of the constant temperature factory is within a small range.

[0047] Currently, in order to increase or decrease the temperature of a gas meter, the gas meter is placed in a constant temperature factory, but this constant temperature method is inefficient.

[0048] In the constant temperature detection system proposed in the present application, multiple ventilation components correspond to multiple ventilation positions of the transmission component. When the transmission component transports the gas meter to any ventilation position, the gas meter can be connected to the ventilation component corresponding to the ventilation position. The ventilation component can transport the gas in the environment to the inside of the gas meter, so that the gas in the environment can exchange heat with the inside of the gas meter, thereby improving the efficiency of the constant temperature of the gas meter. The transmission component can transport the gas meter to any one of the multiple ventilation positions in sequence. Accordingly, the gas meter can be connected to the ventilation component and heat exchanged, so that the gas meter can be fully ventilated to make the temperature of the gas meter closer to the ambient temperature. The ventilation component can also detect the temperature of the gas meter. If the temperature difference between the gas meter and the ventilation component after ventilation and the preset temperature is greater than the preset temperature difference, that is, the temperature difference between the gas meter and the ambient temperature is still large, the transmission component can drive the gas meter to move to the next ventilation position, so that the gas meter can dock with the ventilation component corresponding to the next ventilation position to continue ventilation until the temperature of the gas meter reaches the preset temperature. The conveying assembly can sequentially convey multiple gas meters to multiple ventilation positions, so that multiple gas meters can be sequentially connected to multiple ventilation assemblies and ventilated, to ensure that each gas meter can be fully ventilated with the ventilation assembly, and the ventilation efficiency of the gas meter can be improved. In this way, by conveying the gas meters through the conveying assembly, multiple gas meters can be ventilated with the ventilation assembly in sequence, saving manpower.

[0049] The constant temperature detection system provided by the present application is described in detail below in conjunction with specific embodiments.

[0050] This application proposes a constant temperature detection system, referring to Figure 1 to Figure 2 As shown, it includes a transmission component 500 and a plurality of ventilation components 600. The constant temperature detection system can be used to adjust the temperature of the gas meter so that the temperature of the gas meter can be close to the ambient temperature.

[0051] The transmission component 500 is a basic component of the constant temperature detection system of the present application, and the transmission component 500 can provide an installation foundation for at least part of other components of the constant temperature detection system. The transmission component 500 can be made of metal materials, so that the transmission component 500 has a better structural strength, thereby making the durability and reliability of the transmission component 500 better. Of course, part of the transmission component 500 can also be made of polymer materials, so that the transmission component 500 has a certain structural strength and a lower cost.

[0052] The conveying assembly 500 can be used to carry the gas meter and move the gas meter to a designated area. Specifically, the conveying assembly 500 has a plurality of ventilation positions 510 arranged along a preset direction, and the conveying assembly 500 can convey the gas meter arranged on the conveying assembly 500 to any one of the plurality of ventilation positions 510. In addition, after the conveying assembly 500 conveys the gas meter to any one of the ventilation positions 510, it can continue to convey the gas meter to other ventilation positions 510.

[0053] A plurality of ventilation components 600 are arranged along a preset direction, and the plurality of ventilation components 600 correspond to a plurality of ventilation positions 510 of the conveying component 500. When the conveying component 500 conveys the gas meter to any ventilation position 510, the gas meter can be connected to the ventilation component 600 corresponding to the ventilation position 510. The ventilation component 600 is configured to convey the gas in the external environment to the gas meter 400, so that the gas in the external environment can be heat exchanged with the gas meter 400, thereby reducing the temperature difference between the temperature inside the gas meter 400 and the ambient temperature. When the conveying component 500 conveys the gas meter 400 to the plurality of ventilation positions 510 in sequence, the gas meter 400 can be connected to the plurality of ventilation components 600 in sequence, and each ventilation component 600 can discharge the gas in the gas meter and allow the gas in the environment to enter the gas meter 400, so that the gas meter 400 can be ventilated multiple times, so that the gas meter 400 can be fully heat exchanged, and the temperature difference between the temperature inside the gas meter 400 and the ambient temperature is smaller.

[0054] The ventilation component 600 can also detect the temperature of the gas meter 400. If the temperature difference between the gas meter 400 and the ventilation component 600 after ventilation and the preset temperature is greater than the preset temperature difference, that is, the temperature difference between the gas meter and the ambient temperature is still large, the transmission component 500 can drive the gas meter 400 to move to the next ventilation position 510, so that the gas meter 400 can dock with the ventilation component 600 corresponding to the next ventilation position 510 to continue ventilation until the temperature of the gas meter 400 reaches the preset temperature.

[0055] The number of gas meters 400 that can be carried on the transmission component 500 is multiple, and the transmission component 500 can sequentially transport the multiple gas meters 400 to multiple ventilation positions 510, so that the multiple gas meters 400 can be sequentially connected to multiple ventilation components 600 for ventilation. Therefore, multiple gas meters 400 can be set on the transmission component 500, and the transmission component 500 can automatically transport the multiple gas meters 400 to connect with the multiple ventilation components 600, thereby improving the efficiency of the constant temperature detection system of the present application in making the temperature of the gas meter close to the ambient temperature.

[0056] In some embodiments, reference Figure 3 to Figure 4As shown, in order to connect the gas meter to the ventilation assembly 600 when the gas meter is in the ventilation position 510, the ventilation assembly 600 of the present application may also be provided with a ventilation connection portion 630. After the transmission assembly 500 transports the gas meter to the ventilation position 510, the gas outlet of the gas meter 400 may be connected to the corresponding ventilation connection portion 630 of the ventilation assembly 600, and the ventilation assembly 600 may extract the gas in the gas meter 400 through the gas outlet, and accordingly, the gas in the environment may enter the gas meter 400 through the air inlet of the gas meter 400, so that the environmental gas may circulate through the gas meter 400. In this way, the gas in the environment can be continuously transported to the inside of the gas meter 400, and discharged through the gas outlet of the gas meter 400 after absorbing the heat inside the gas meter 400.

[0057] In some embodiments, reference Figure 3 to Figure 4 As shown, in order to enable the ventilation component 600 to extract the gas in the gas meter through the gas outlet, the ventilation component 600 may be provided with a housing 610 and an air pump 620 and the housing 610. The housing 610 has a ventilation cavity 611, the air pump 620 may be provided in the housing 610, and the air inlet end of the air pump 620 may be communicated with the ventilation cavity 611 of the housing 610, so that the air pump 620 can extract the gas in the ventilation cavity 611 of the housing 610, thereby reducing the air pressure in the ventilation cavity 611. The ventilation connection part 630 may be connected to the ventilation cavity 611, so that the ventilation cavity 611 is connected to the gas outlet of the gas meter 400 through the ventilation connection part 630. When the air pump 620 is turned on to reduce the air pressure in the ventilation chamber 611, the air pressure in the gas meter 400 is greater than the air pressure in the ventilation chamber 611, the gas in the gas meter 400 will enter the ventilation chamber 611, and the gas in the environment will enter the gas meter 400, thereby ventilating the gas meter 400.

[0058] Of course, in other embodiments, an air pump 620 may be provided to transport gas in the environment into the ventilation chamber 611 to increase the air pressure in the ventilation chamber 611. In this way, the gas in the ventilation chamber 611 may be transported to the gas meter 400 through the ventilation connection portion 630 to squeeze the gas in the gas meter out of the gas meter 400, thereby achieving the purpose of ventilating the gas meter 400.

[0059] In some embodiments, the ventilation connection part 630 may also include a temperature detection part. When the ventilation connection part 630 is connected to the gas meter 400, the temperature detection part can detect the temperature of the gas meter 400, thereby determining whether the gas meter 400 needs ventilation for heat exchange. Specifically, if the difference between the temperature of the gas meter 400 and the ambient temperature is below a threshold, it indicates that the gas meter 400 does not need to continue ventilation. If the difference between the temperature of the gas meter 400 and the ambient temperature reaches a threshold or is greater than a threshold, it indicates that the gas meter 400 needs to continue ventilation.

[0060] A flow valve can also be set in the ventilation connection part 630, and the flow valve can control the flow rate of gas extracted from the gas meter 400 by the ventilation connection part 630. In this way, the ventilation connection part 630 can detect the temperature of the gas meter 400 according to the temperature detection part, and open or close the ventilation with the gas meter 400 through the flow valve control, so as to make the temperature control of the gas meter 400 more precise.

[0061] In some embodiments, reference Figure 3 to Figure 4 As shown, in order to enable the gas meter 400 to be connected to the ventilation connection part 630 after being moved to the ventilation position 510, the ventilation connection part 630 can be provided to be movably connected to the housing 610. When the gas meter 400 is located at the ventilation position 510, the gas outlet of the gas meter 400 is opposite to the ventilation connection part 630, and the ventilation connection part 630 can be driven to move to dock with the gas outlet of the gas meter 400, so that the ventilation connection part 630 is connected to the gas meter 400, so that the gas outlet of the gas meter 400 can be connected to the ventilation connection part 630 after the conveying assembly 500 conveys the gas meter 400 to the ventilation position 510, thereby simplifying the structure of the conveying assembly 500.

[0062] In some embodiments, reference Figure 3 to Figure 4 As shown, in order to enable the ventilation connection part 630 to be driven to move to dock with the air outlet of the gas meter 400, the ventilation component 600 of the present application can also be provided with a driving part 640, and the driving part 640 is arranged on the shell 610, and one end of the driving part 640 is connected to the ventilation connection part 630. The driving part 640 can drive the ventilation connection part 630 to move toward the air outlet of the gas meter, so that the ventilation connection part 630 can be moved to dock with the air outlet of the gas meter.

[0063] In some embodiments, reference Figure 1 As shown, in order to improve the ventilation efficiency of the constant temperature detection system of the present application and the gas meter 400, the number of the ventilation connection parts 630 of the ventilation assembly 600 can be set to multiple, and the multiple ventilation connection parts 630 are all connected to the ventilation cavity 611 of the shell 610. Correspondingly, the driving part 640 can drive the multiple ventilation connection parts 630 to move simultaneously. The transmission assembly 500 can transport multiple gas meters 400 to the same ventilation position 510 at one time, so that the gas outlets of the multiple gas meters 400 can be respectively opposite to the multiple ventilation connection parts 630. The driving part 640 can drive the multiple ventilation connection parts 630 to move simultaneously to the gas outlets of the multiple gas meters 400, so that the multiple gas meters 400 can be connected to the same ventilation assembly 600, so that the multiple gas meters 400 can be ventilated at the same time, thereby further improving the efficiency of the constant temperature detection system of the present application in processing gas meters.

[0064] Therefore, a larger number of gas meters 400 can be arranged on the transmission assembly 500 of the present application, and a plurality of gas meters 400 can constitute a gas meter group, and the number of gas meter groups is multiple. After the transmission assembly 500 transports the gas meters 400 in a gas meter group to the same ventilation position 510, the plurality of gas meters 400 in the gas meter group can be ventilated with the corresponding ventilation assembly 600 at the same time.

[0065] In some embodiments, reference Figure 4 As shown, in order to enable the driving member to drive the multiple ventilation connection parts 630 of the ventilation assembly 600 to dock with the gas outlets of multiple gas meters, the ventilation assembly 600 may also be provided with a driving plate 650. The ventilation connection part 630 may be provided with a first pipe section 631 and a second pipe section 632. One end of the first pipe section 631 is communicated with the ventilation cavity 611 of the housing 610, and the other end of the first pipe section 631 is connected to the second pipe section 632. The second pipe section 632 is movably connected to the first pipe section 631, and the second pipe section 632 is also connected to the driving plate 650. The driving plate 650 is connected to the output end of the driving part 640. The driving part 640 can control the driving plate 650 to move, thereby driving the second pipe section 632 to move relative to the first pipe section 631, until the end of the second pipe section 632 away from the first pipe section 631 docks with the gas outlet of the gas meter 400. In this way, the second pipe sections 632 of the plurality of ventilation connection parts 630 can be connected to the gas outlets of the plurality of gas meters 400 respectively.

[0066] Specifically, the second pipe section 632 can be sleeved on the first pipe section 631, and the second pipe section 632 is connected to the driving plate 650, and one end of the second pipe section 632 is opposite to the gas outlet of the gas meter. The driving plate 650 moves toward the gas meter 400 to move the second pipe sections 632 of the plurality of ventilation connection parts 630 toward the gas meter 400 until the second pipe section 632 is connected to the gas outlet of the gas meter 400.

[0067] In addition, the second pipe section 632 can also be connected to the housing 610 through an elastic member, so that after the driving unit 620 drives the second pipe section 632 to move to dock with the gas meter 400, the elastic member can be deformed. When the gas meter 400 completes the ventilation, the driving unit 620 no longer drives the second pipe section 632, and the elastic restoring force of the elastic member drives the second pipe section 632 to reset.

[0068] In addition, in other embodiments, the ventilation connection part 630 may be provided with a longer length, and one end of the ventilation connection part 630 is located in the ventilation cavity 611 of the housing 610. When the driving plate 650 drives the ventilation connection part 630 to move toward the gas meter as a whole, the end of the ventilation connection part 630 located in the ventilation cavity 611 of the housing 610 remains in the ventilation cavity 611, so that the ventilation connection part 630 can always be connected to the ventilation cavity 611.

[0069] In some embodiments, reference Figure 3 to Figure 4 As shown, the driving part 640 of the present application can be a cylinder, and the output end of the driving part 640 can be connected to the ventilation connection part 630. The driving part 640 can be fixed in the shell 610, and the output end of the driving part 640 passes through the shell 610 to the outside of the shell 610 to connect with the driving plate 650, so that the driving part 640 can use the space of the ventilation cavity 611 of the shell 610, so that the driving plate 650 can be closer to the shell 610, so that the structure of the ventilation component 600 is more compact and occupies less space.

[0070] In some embodiments, reference Figure 3 As shown, the ventilation component 600 of the present application can be arranged above the ventilation position 510 of the transmission component 500. Accordingly, the driving part 640 controls the driving plate 650 to move downward so that the multiple ventilation connection parts 630 can be connected with the multiple gas meter outlets.

[0071] In some embodiments, the constant temperature detection system of the present application may also include a control module 520, which may be electrically connected to the conveying assembly 500 and the ventilation assembly 600. When the gas meter 400 is installed on the conveying assembly 500, the control module 520 may control the conveying assembly 500 to drive the gas meter 400 to move to the ventilation position 510, and the control module 520 may also control the driving part 620 to start to drive the ventilation connection part 630 to move to dock with the gas meter 400. The temperature detection part may detect the temperature of the gas meter 400. If the temperature difference between the temperature of the gas meter 400 and the ambient temperature is greater than or equal to the preset temperature, the control module 520 controls the gas pump 620 to start to extract gas from the gas meter 400. If the temperature difference between the temperature of the gas meter 400 and the ambient temperature is less than the preset temperature, the control module 520 controls the conveying assembly 500 to drive the gas meter 400 to continue to move along the preset direction to the end of the conveying assembly 500.

[0072] In some embodiments, reference Figure 5 As shown, in order to make the gas meter more stable when it is arranged on the conveying assembly 500, the constant temperature detection system of the present application can also be provided with a tray assembly, the gas meter can be arranged on the tray assembly, and the tray assembly is arranged on the conveying assembly 500. The conveying assembly 500 can transport the tray assembly to the ventilation position 510, so that the gas meter on the tray assembly can be transported to the ventilation position 510.

[0073] Specifically, the two sides of the conveying assembly 500 are provided with transmission wheels, and the tray assembly can be mounted on the transmission wheels. After the transmission wheels rotate, the tray assembly can be driven to move along a preset direction.

[0074] In some embodiments, reference Figure 5 As shown, the tray assembly may include a tray body 100 , an elastic member 200 and a limiting plate 300 .

[0075] The pallet body 100 is the basic component of the pallet assembly of the present application. The pallet body 100 can provide a mounting base for at least some of the other components of the pallet assembly and protect at least some of the other components. The pallet body 100 can be made of metal material, so that the pallet body 100 has better structural strength, thereby making the durability and reliability of the pallet body 100 better. Of course, the pallet body 100 can also be made of polymer material, so that the pallet body 100 has a certain structural strength and is relatively light.

[0076] The tray body 100 includes an installation cavity 140, which is a cavity structure in the tray body 100. The installation cavity 140 of the tray body 100 can be used to set the gas meter 400. When the gas meter 400 is located in the installation cavity 140, the gas meter 400 can be fixed on the push plate body. The tray body 100 also includes a first opening 150, which is an opening on the surface of the tray body 100. The first opening 150 is connected to the installation cavity 140 of the tray body 100, so that the installation cavity 140 can be connected to the outside of the installation cavity 140 through the first opening 150. The first opening 150 is located opposite to the bottom wall of the installation cavity 140, and accordingly, the first opening 150 is located on the top side of the installation cavity 140. When the gas meter 400 needs to be installed in the installation cavity 140 , the gas meter 400 can be placed in the installation cavity 140 from above the installation cavity 140 through the first opening 150 , making the process of placing the gas meter 400 in the installation cavity 140 simpler and more convenient.

[0077] The tray body 100 further includes a second opening 160, which is an opening on the surface of the tray body 100. The second opening 160 is connected to the mounting cavity 140 of the tray body 100, so that the mounting cavity 140 can be connected to the outside of the mounting cavity 140 through the second opening 160. The second opening 160 is located on one side of the mounting cavity 140, so that the second opening 160 is perpendicular to the bottom wall of the mounting cavity 140, that is, the direction of the second opening 160 is parallel to the bottom wall of the mounting cavity 140, and accordingly, the direction of the second opening 160 intersects with the direction of the first opening 150. Specifically, the opening of the second opening 160 is Figure 1 The X-axis direction.

[0078] When the gas meter 400 is located in the installation cavity 140 of the tray body 100, at least part of the outer walls on the opposite sides of the gas meter 400 can abut against the inner walls on both sides of the second opening 160 in the installation cavity 140. Specifically, the installation cavity 140 includes a first inner wall and a second inner wall, the first inner wall and the second inner wall are arranged opposite to each other, and the first inner wall and the second inner wall are located on both sides of the second opening 160. The outer walls on the opposite sides of the gas meter 400 can abut against the first inner wall and the second inner wall respectively, so that the first inner wall and the second inner wall can limit the gas meter 400 in a direction parallel to the bottom wall of the installation cavity 140 and intersecting with the direction of the second opening 160, that is, Figure 1 In the Y direction, the gas meter 400 is prevented from being displaced in the above direction after being acted upon by an external force, so that the gas meter 400 can remain stable.

[0079] The limiting plate 300 is movably disposed on the tray body 100, so that the limiting plate 300 can move relative to the tray body 100. The limiting plate 300 is opposite to the second opening 160 of the tray body 100, and the limiting plate 300 can be driven to move toward the second opening 160 or away from the second opening 160. When the limiting plate 300 moves toward the second opening 160, the limiting plate 300 can eventually move to block the second opening 160. At this time, if the gas meter 400 is located in the installation cavity 140, the limiting plate 300 can be opposite to the outer wall of the gas meter 400 facing the second opening 160. The limiting plate 300 cooperates with the tray body 100 to limit the gas meter 400 in the installation cavity 140, thereby preventing the gas meter from escaping from the installation cavity 140 from the second opening 160 to a certain extent. In addition, since the first opening 150 is located at the top side of the installation cavity 140, the gas meter 400 in the installation cavity 140 will not move out of the installation cavity 140 from the first opening 150 due to its own gravity. In this way, the gas meter 400 can be stably fixed in the installation cavity 140.

[0080] When the volume of the gas meter 400 is large, so that part of the gas meter 400 extends out of the installation cavity 140 from the second opening 160, the gas meter 400 can push the limiting plate 300 to move in the direction away from the second opening 160, and the limiting plate 300 can limit the gas meter 400 in the direction of the second opening 160, thereby preventing the gas meter 400 from moving out of the installation cavity 140 from the second opening 160 under the action of external force to a certain extent. In this way, the gas meter 400 can be limited in multiple directions when it is set in the installation cavity 140, and the gas meter 400 can remain stable.

[0081] The elastic member 200 is connected to both the tray body 100 and the limiting plate 300. When the limiting plate 300 moves, the elastic member 200 can be deformed, so that the elastic member 200 includes a first state and a second state. When the elastic member 200 is in the first state, the elastic member 200 is in a deformed state, and the elastic force of the elastic member 200, that is, the restoring deformation force of the elastic member 200 acts on the limiting plate 300, so that the limiting plate 300 can be pressed on the part of the tray body 100 located around the second opening 160. In this way, the limiting plate 300 can be close to the second opening 160, so that the limiting plate 300 and the tray body 100 can surround the gas meter 400 in the installation cavity 140. Specifically, the limiting plate 300 can block the second opening 160.

[0082] When the limit plate 300 moves in the direction away from the second opening 160, the elastic member 200 may be further deformed by force, and the elastic member 200 switches to the second state, and the deformation degree and elastic force of the elastic member 200 increase. The restoring deformation force of the elastic member 200 can drive the limit plate 300 to move toward the second opening 160. Therefore, when the volume of the gas meter 400 is large, so that part of the gas meter 400 extends from the second opening 160 to the outside of the installation cavity 140, the gas meter 400 can push the limit plate 300 to move in the direction away from the second opening 160, so that the deformation degree of the elastic member 200 increases. The elastic force of the elastic member 200, that is, the restoring deformation force of the elastic member 200, drives the limiting plate 300 to move toward the second opening 160, so that the limiting plate 300 can be pressed against the outer wall of one side of the gas meter 400, so as to achieve the purpose of fixing the gas meter 400 in the direction of the second opening 160, so that the gas meter 400 is more stable when it is set in the installation cavity 140. In this way, the stability of the tray assembly when moving on the assembly line is better, and the gas meter 400 can always be confined in the installation cavity 140, thereby improving the operating efficiency of the constant temperature detection system of the present application.

[0083] When the gas meter 400 needs to be installed in the installation cavity 140 of the tray body 100, the limiting plate 300 can be pushed to move away from the second opening 160, and then the gas meter 400 is placed into the installation cavity 140 from the first opening 150, and the outer walls of the gas meter 400 on the opposite sides are ensured to abut against the first inner wall and the second inner wall of the installation cavity 140. Then, the limiting plate 300 is released, so that the limiting plate 300 can block the second opening 160 under the elastic restoring force of the elastic member 200, or the limiting plate 300 is pressed against the gas meter 400.

[0084] In some embodiments, reference Figure 6As shown, in order to form the installation cavity 140, the first opening 150 and the second opening 160 of the pallet body 100 of the present application, the pallet body 100 may be provided with a bearing plate 110 and a positioning frame 120. The bearing plate 110 is the basic component of the pallet body 100 of the present application, and the bearing plate 110 may provide an installation foundation for at least some of the other components of the pallet body 100 and protect at least some of the other components.

[0085] The carrier plate body 110 includes a carrier plate surface 111, which is a side plate surface of the carrier plate body 110. The positioning frame 120 is disposed on the carrier plate surface 111 of the carrier plate body 110. The positioning frame 120 is a frame structure. The positioning frame 120 and the carrier plate body 110 can be surrounded to form a mounting cavity 140. Accordingly, the carrier plate surface 111 of the carrier plate body 110 constitutes the bottom wall of the mounting cavity 140, and the side wall of the positioning frame 120 can constitute the inner side wall of the mounting cavity 140. The first opening 150 is located on the side of the positioning frame 120 away from the carrier plate body 110, and the second opening 160 is located on the side of the positioning frame 120.

[0086] Specifically, the side wall of the positioning frame 120 can constitute the first inner wall and the second inner wall of the installation cavity 140. Accordingly, when the gas meter 400 is arranged in the installation cavity 140, the opposite sides of the gas meter 400 can respectively abut against the positioning frame 120, and the positioning frame 120 can serve to limit the gas meter 400. The side of the positioning frame 120 and the bearing plate body 110 can be surrounded to form the second opening 160, and the limiting plate 300 is movably arranged on the bearing plate body 110, and the limiting plate 300 is located on one side of the positioning frame 120. The limiting plate 300 can move toward the positioning frame 120 or away from the positioning frame 120, so that the limiting plate 300 can move toward the second opening 160 or away from the second opening 160.

[0087] When the elastic member 200 is in the first state, the elastic force of the elastic member 200 can drive the limit plate 300 to counteract the parts of the positioning frame 120 located on both sides of the second opening 160, so that the limit plate 300 can be pressed against the positioning frame 120, so that the limit plate 300 can better block the second opening 160.

[0088] When preparing the tray body 100 of the present application, the supporting plate body 110 and the positioning frame body 120 may be prepared separately, and then the supporting plate body 110 and the positioning frame body 120 may be connected, thereby reducing the difficulty of the manufacturing process of the tray body 100 .

[0089] In some embodiments, reference Figure 6 and Figure 7As shown, in order to connect the positioning frame 120 of the present application with the carrier plate 110, the positioning frame 120 can be configured to include a positioning sheet 121 and a fixing sheet 122. The fixing sheet 122 is connected to the positioning sheet 121, the fixing sheet 122 is superimposed and fixed on the carrier plate surface 111, the positioning sheet 121 is perpendicular to the carrier plate surface 111, and the fixing sheet 122 is located outside the installation cavity 140.

[0090] Among them, the positioning sheet body 121 and the fixed sheet body 122 are both sheet-mounted structural parts. When the fixed sheet body 122 is stacked on the bearing plate surface 111 of the bearing plate body 110, the thickness direction of the fixed sheet body 122 is perpendicular to the bearing plate surface 111, so that the contact area between the fixed sheet body 122 and the bearing plate surface 111 is larger, thereby making the connection between the fixed sheet body 122 and the bearing plate body 110 more stable and reliable. The positioning sheet body 121 can be connected with the fixed sheet body 122, so that the positioning sheet body 121 and the bearing plate body 110 can be relatively fixed. The positioning sheet body 121 is perpendicular to the bearing plate surface 111, so that the positioning sheet body 121 can also be perpendicular to the fixed sheet body 122, the outer wall of the positioning sheet body 121 can constitute the inner wall of the installation cavity 140, and the first opening 150 can be located on the side of the positioning sheet body 121 away from the fixed sheet body 122.

[0091] At least part of the orthographic projection of the fixing sheet 122 on the bearing plate surface 111 is located outside the installation cavity 140, so that part of the fixing sheet 122 can be located outside the installation cavity 140, which can reduce the space in the installation cavity 140 occupied by the fixing sheet 122. When the orthographic projection of the fixing sheet 122 on the bearing plate surface 111 is completely located outside the installation cavity 140, the bottom wall of the installation cavity 140 is a plane completely formed by the bearing plate surface 111. In this way, when the gas meter 400 is set in the installation cavity 140, the bottom wall of the gas meter 400 can fully contact the inner wall of the installation cavity 140, so that the gas meter 400 is more stable when it is set in the installation cavity 140.

[0092] In some embodiments, reference Figure 6 As shown, in order to make the fixing sheet 122 fixedly connected to the carrier plate 110, the fixing sheet 122 and the carrier plate 110 may be provided with corresponding fixing holes 124, and the fixing member may be installed in the fixing hole 124, so that the fixing sheet 122 and the carrier plate 110 are fixed. Specifically, the fixing hole 124 may be a screw hole, and the fixing member may be a screw, so that the fixing sheet 122 and the carrier plate 110 can be detachably connected, thereby facilitating the maintenance of the tray assembly of the present application. Of course, the fixing sheet 122 and the carrier plate 110 may also be fixed by riveting or bonding.

[0093] In some embodiments, reference Figure 7As shown, in order to facilitate the gas meter 400 to be installed in the installation cavity 140 through the first opening 150 of the tray body 100, the positioning frame 120 may also be provided with a guide sheet 123. The guide sheet 123 is provided on a side of the positioning sheet 121 away from the fixed sheet 122, and the guide sheet 123 extends in a direction away from the bearing plate surface 111, and the guide sheet 123 is folded relative to the positioning sheet 121 in a direction away from the installation cavity 140.

[0094] The guide sheet 123 is disposed on a side of the positioning sheet 121 away from the fixed sheet 122, so that the first opening 150 is located on a side of the guide sheet 123 away from the positioning sheet 121. The guide sheet 123 extends in a direction away from the bearing plate surface 111, and the guide sheet 123 is folded relative to the positioning sheet 121 in a direction away from the installation cavity 140, so that the guide plate can be bent relative to the positioning sheet 121, so that the surface of the guide sheet 123 can form an inclined surface, so that the guide sheet 123 is an outward expansion structure in a direction away from the bearing plate surface 111. When the gas meter 400 is installed in the installation cavity 140 through the first opening 150, the outer wall of the guide sheet 123 can serve the purpose of guiding the gas meter 400, so that the gas meter 400 can be more conveniently installed in the installation cavity 140 through the first opening 150.

[0095] In some embodiments, the positioning frame 120 of the present application can be an integrated structure. Accordingly, when the material of the positioning frame 120 is metal, the metal plate can be bent through a sheet metal process to form a structure in which the two sides of the positioning sheet 121 are respectively connected to the bent fixed sheet 122 and the guide sheet 123. This can make the structural integrity and stability of the positioning frame 120 better.

[0096] In some embodiments, reference Figure 8 and Fig. 9 As shown, in order to allow the elastic member 200 of the present application to deform when the limiting plate 300 moves away from the second opening 160, the elastic member 200 may be provided with a connecting rod 210 and an elastic part 220. The connecting rod 210 is movably provided on the tray body 100, the limiting plate 300 is connected to the connecting rod 210, and the elastic part 220 is connected to the connecting rod 210. When the limiting plate 300 moves away from the second opening 160, the connecting rod 210 may be driven to move in a direction away from the second opening 160. The connecting rod 210 is connected to the elastic part 220, so that when the connecting rod 210 moves, the end of the elastic part 220 connected to the connecting rod 210 may be driven to move together, thereby increasing the deformation degree of the elastic part 220, and further increasing the elastic force of the elastic part 220.

[0097] In some embodiments, reference Fig. 9As shown, the elastic part 220 of the present application can be specifically set as a spring, so that the elastic part 220 can be sleeved on the connecting rod 210, and one end of the elastic part 220 can be against the tray body 100, so that the tray body 100 can limit the elastic part 220 in one direction, and the other end of the elastic part 220 is against the connecting rod 210. When the limiting plate 300 and the positioning frame 120 are against each other to block the second opening 160, the elastic part 220 is compressed by the connecting rod 210 and the tray body 100. When the connecting rod 210 moves with the limiting plate 300 back to the second opening 160, the connecting rod 210 can further compress the elastic part 220, so that the deformation degree of the elastic part 220 increases, so that the elastic force of the elastic part 220 is further increased. The elastic part 220 is sleeved on the connecting rod 210 so that the elastic part 220 is more closely connected to the connecting rod 210, and the elastic part 220 is prevented from separating from the connecting rod 210 during the deformation process of the elastic part 220 under force. In addition, the connecting rod 210 can also guide the elastic part 220 to deform, preventing the elastic part 220 from bending during the deformation process, thereby protecting the elastic part 220.

[0098] When the limiting plate 300 abuts against the positioning frame 120 to block the second opening 160, the elastic part 220 is pressed by one end of the connecting rod 210 and the tray body 100, so that the elastic part 220 is compressed, and the restoring deformation force of the elastic part 220 can push the limiting plate 300 to be tightly against the positioning frame 120. When the limiting plate 300 moves in a direction away from the second opening 160, one end of the connecting rod 210 can further press the elastic part 220, so that the compression degree of the elastic part 220 increases, thereby further increasing the restoring deformation force of the elastic part 220, so that the elastic part 220 can drive the limiting plate 300 to press against the gas meter 400 with a greater force, and the limiting plate 300 has a better effect of fixing the gas meter 400.

[0099] Specifically, the connecting rod 210 may include a rod body 211 and a limiting cap 212, one end of the limiting cap 212 is connected to the rod body 211, and the outer diameter of the limiting cap 212 is greater than the outer diameter of the rod body 211. In this way, when the elastic part 220 is sleeved on the rod body 211 of the connecting rod 210, one end of the elastic part 220 can be abutted against the limiting cap 212, so that one end of the elastic part 220 can be abutted against the connecting rod 210.

[0100] In some embodiments, reference Figure 6 , Figure 8 and Fig. 9 As shown, the number of the positioning frames 120 of the present application can be set to multiple, and the multiple positioning frames 120 are arranged at intervals along a preset direction. The preset direction is Figure 5 , Figure 6 and Figure 8The Y direction in the figure. A plurality of positioning frames 120 are all arranged on the carrier plate 110, and the plurality of positioning frames 120 and the carrier plate 110 can be surrounded to form a plurality of installation cavities 140, and accordingly, the number of the first opening 150 and the second opening 160 is also plural. Gas meters 400 can be installed in the plurality of installation cavities 140, so that the tray assembly of the present application can carry more gas meters 400, so that a plurality of gas meters 400 can be transported to the ventilation position 510 at one time through the tray assembly, thereby improving the working efficiency of the constant temperature detection system.

[0101] Multiple positioning frames 120 can be connected by connecting pieces 130, and the connecting pieces 130 can serve the purpose of fixing adjacent positioning frames 120. In this way, multiple positioning frames 120 are respectively fixed to the supporting plate 110, and adjacent positioning frames 120 are also fixed, which can make the structure of multiple positioning frames 120 more stable.

[0102] The connecting piece 130 can be an integral structure with the adjacent positioning frame 120, so that the connection between the connecting piece 130 and the adjacent positioning frame 120 is more stable and reliable. Specifically, the connecting piece 130 and the plurality of positioning frames 120 are both made of metal materials, and the metal sheet can be bent through a sheet metal process to form the plurality of positioning frames 120 and the connecting piece 130, so that it is not necessary to connect the plurality of positioning frames 120 separately, thereby reducing the preparation process and preparation cost of the tray assembly of the present application.

[0103] The connecting rod 210 is movably arranged on the connecting piece 130, so that the connecting rod 210 can move relative to the connecting piece 130. Specifically, the connecting rod 210 is provided with a through hole for the connecting rod 210 to pass through, and the inner diameter of the through hole of the connecting piece 130 is larger than the outer diameter of the connecting rod 210. In this way, the connecting rod 210 can be mounted on the connecting piece 130, and the connecting rod 210 can reciprocate relative to the connecting piece 130 along its axial direction. The two ends of the connecting rod 210 are respectively located on opposite sides of the connecting piece 130, one end of the connecting rod 210 is connected to the limiting plate 300, and the other end of the connecting rod 210 is against the elastic part 220.

[0104] In some embodiments, reference Figure 5 , Figure 6 and Figure 8 As shown, the directions of the second openings 160 corresponding to the multiple positioning frames 120 of the present application can be set to be consistent, and accordingly, the limiting plate 300 can be extended along the preset direction of the arrangement of the multiple positioning frames 120, so that the limiting plate 300 can move toward or away from the multiple second openings 160 at the same time, so that the gas meters 400 in multiple installation cavities 140 can be limited by one limiting plate 300 at the same time. In this way, it is not necessary to separately set multiple limiting plates 300 for the multiple second openings 160, which simplifies the structure of the tray assembly of the present application.

[0105] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation modes of the present application.
