[0039] Below, this application is described in detail.

[0040] The object to be dried needs to be placed in an oven to dry it. For example, after the combined sensor is injected with glue, in order to quickly shape the combined sensor, a special oven is usually used to dry the combined sensor. Of course, the object to be dried can also be other devices, and this is not limited to the embodiments of the present application.

[0041] For the convenience of transportation, in the related art, the objects to be dried are placed on a cart, which is then placed in an oven. However, due to the design of the cart's own structure, the cart at the bottom cannot limit the rollers of the cart above, resulting in the carts being unable to be stacked in the oven. The oven can only dry the objects to be dried on one cart at a time, resulting in low utilization efficiency of the oven.

[0042] The present application embodiment provides a cart, please refer to Figure 1 , Figure 6 or Figure 8 The cart includes a roller 121, a bottom support 122 and a side stopper 123, wherein the roller 121 is arranged on the bottom support 122, the side stopper 123 is arranged on the bottom support 122 along the circumference of the bottom support 122, the side stopper 123 extends in a direction away from the roller 121, the side wall of the side stopper 123 and the bottom support 122 form a first accommodation portion, the first accommodation portion is used to accommodate the object to be dried 2, and a second accommodation portion 1231 is arranged on the side of the side stopper 123 away from the bottom support 122, the second accommodation portion 1231 is adapted to the roller 121, please refer to Figure 5 or Figure 7 When a plurality of carts are stacked in sequence along the first direction A, in any two adjacent carts, the roller 121 of the upper cart is at least partially embedded in the second receiving portion 1231 of the lower cart.

[0043] In the embodiment of the present application, the cart can be made of stainless steel, or iron, or other materials, which is not limited in the embodiment of the present application. In one possible implementation provided by the embodiment of the present application, the cart is made of stainless steel, so that the weight of the cart as a whole can be reduced while ensuring strength.

[0044] In the embodiment of the present application, the roller 121 may be a universal wheel. Of course, the roller 121 may also be a fixed wheel. Here, it should be additionally explained that the embodiment of the present application does not limit the type of the roller 121.

[0045] In the embodiment of the present application, there are multiple rollers 121, and correspondingly, multiple second receiving portions 1231 should also be provided on the side stopper 123. In one example, please refer to Figure 1 When the bottom support member 122 is a square structure, there may be four rollers 121, and the four rollers 121 are respectively arranged at the four corners of the bottom support member 122; in another example, when the bottom support member 122 is a disc-shaped structure, there may be four rollers 121, and the four rollers 121 are arranged on the edge of the disc, and the interval between two adjacent rollers 121 is 90 degrees. This embodiment of the present application is also not limited to this.

[0046] In the embodiment of the present application, the side stopper 123 is disposed on the bottom support member 122 along the circumferential side of the bottom support member 122. In one example, please refer to Figure 1, the bottom support member 122 is a square structure, and correspondingly, the side stopper 123 is also a square structure; in another example, if the bottom support member 122 is a disc-shaped structure, then correspondingly, the side stopper 123 is also a disc-shaped structure, and this embodiment of the application does not limit this.

[0047] In the embodiment of the present application, the side stopper 123 and the bottom support member 122 can be integrally formed. Of course, the side stopper 123 and the bottom support member 122 can also be separately formed, such as the side stopper 123 is screwed on the bottom support member 122, such as the side stopper 123 is clamped on the bottom support member 122, and the embodiment of the present application is not limited to this. Here, it should be supplemented that if the side stopper 123 and the bottom support member 122 are separately formed, the reliability of the connection method between the side stopper 123 and the bottom support member 122 should not be affected by the oven temperature.

[0048] In the embodiment of the present application, the object to be dried 2 can be a combination sensor, and of course, can also be other types of items, which is not limited by the embodiment of the present application. In an implementable manner provided in the embodiment of the present application, the object to be dried 2 is a combination sensor.

[0049] A combined sensor is a sensor that integrates multiple sensors to detect and measure multiple physical quantities, forming a more powerful sensor system. The multiple physical quantities can be voltage, current, capacitance, etc. The combined sensor is used in situations where it is necessary to obtain information on multiple physical quantities at the same time, such as pole-mounted circuit breakers, autonomous vehicles, drones, industrial automation control systems, etc. In one possible implementation provided in an embodiment of the present application, the combined sensor is applied to a pole-mounted circuit breaker.

[0050] The pole-mounted circuit breaker is used in the process of cable transmission. The pole-mounted circuit breaker includes a pole. A first port for cable connection and a second port for cable connection are arranged on the pole. A flexible connecting line is arranged between the first port and the second port for connecting the cable of the first port and the cable of the second port. The pole-mounted circuit breaker also includes a control unit and a combination sensor. The combination sensor is used to obtain physical quantities of the flexible connecting line, such as current, voltage, etc. When the measured physical quantity is abnormal, the combination sensor transmits a signal to the control unit, and the control unit controls the flexible connecting line to be disconnected to protect the cable.

[0051] During the process of processing the combined sensor, it is necessary to inject glue into the combined sensor. However, in order to quickly shape the combined sensor, it is necessary to dry the combined sensor. In the embodiment of the present application, when the object 2 to be dried is a combined sensor, the glue injection port of the combined sensor can be directed toward the side stopper 123 away from the bottom support member 122, which can also be called vertical placement. In this way, the combined sensor can be placed in the first accommodating portion before glue injection to reduce the phenomenon that the combined sensor is easy to tip over and the colloid flows out of the glue injection port of the combined sensor when the combined sensor is placed in the first accommodating portion after glue injection.

[0052] For details, please refer to Figure 1 , Figure 5 or Figure 7 In any two adjacent carts, the rollers 121 of the upper cart may be fully embedded in the second accommodating portion 1231 of the lower cart, or the rollers 121 of the upper cart may be only partially embedded in the second accommodating portion 1231 of the lower cart, and the embodiment of the present application does not limit this. In an implementable manner provided by the embodiment of the present application, the rollers 121 of the upper cart are fully embedded in the second accommodating portion 1231 of the lower cart, without occupying the space of the first accommodating portion of the lower cart, further improving the space utilization rate of the lower cart for accommodating the objects 2 to be dried.

[0053] In the cart provided in the embodiment of the present application, in any two adjacent carts, the roller 121 of the upper cart is at least partially embedded in the second accommodating portion 1231 of the lower cart, which is equivalent to the second accommodating portion 1231 of the lower cart limiting at least a portion of the roller 121 of the upper cart. In other words, the provision of the second accommodating portion 1231 enables the two adjacent carts to be stacked along the first direction A, thereby realizing the stacking of multiple carts, and each cart is placed with objects 2 to be dried. The multiple stacked carts are placed in an oven, and the oven can dry the objects 2 to be dried in each cart at the same time. In the related art, since the carts cannot be stacked, the oven can only dry the objects 2 to be dried in one cart at a time, resulting in a technical problem of low utilization efficiency of the oven. Compared with the related art, the cart provided in the embodiment of the present application can improve the utilization efficiency of the oven.

[0054] The present application embodiment provides a cart, please refer to Figure 1 There are multiple rollers 121, the bottom support member 122 is a polygon, the multiple rollers 121 are arranged at the corners of the bottom support member 122, and the side stopper 123 is provided with multiple second accommodating portions 1231 on the side away from the bottom support member 122. The number of the multiple second accommodating portions 1231 is the same as the number of the multiple rollers 121. Please refer to Figure 5 or Figure 7In any two adjacent carts, at least part of the multiple rollers 121 of the upper cart are embedded in the multiple second accommodating portions 1231 of the lower cart in a one-to-one correspondence.

[0055] In the present application, please refer to Figure 5 There are four rollers 121, and the bottom support member 122 is a quadrilateral. The multiple rollers 121 are respectively arranged at the four corners of the bottom support member 122, and four second accommodating portions 1231 are arranged on the side of the side stopper 123 away from the bottom support member 122. In any two adjacent carts, at least parts of the four rollers 121 of the upper cart are embedded in the four second accommodating portions 1231 of the lower cart in a one-to-one correspondence.

[0056] The cart provided in the embodiment of the present application has a plurality of rollers 121 disposed at the corners of the bottom support member 122 , thereby improving the overall stability of the cart.

[0057] The present application embodiment provides a cart, please refer to Figure 1 as well as Figure 3 The side stopper 123 includes a first side stopper 1232 and a plurality of second side stoppers 1233. The first side stopper 1232 is a polygon having the same outer contour as the bottom support member 122. The first side stopper 1232 is arranged on the bottom support member 122 along the circumference of the bottom support member 122. The plurality of second side stoppers 1233 are respectively arranged on a plurality of sides of the first side stopper 1232. There is a gap between two second side stoppers 1233 located on adjacent sides, and the gap forms a second accommodating portion 1231.

[0058] In addition to the method of forming the second receiving portion 1231 by a gap between two second side stoppers 1233 located at adjacent edges, the second receiving portion 1231 may also be formed in other ways, and the present embodiment of the application does not limit this. Figure 2 The second accommodation portion 1231 can be formed by directly digging a groove on the wall of the second side stopper 1233 which is away from the first side stopper 1232 .

[0059] In the embodiment of the present application, the multiple second side stop portions 1233 can be directly integrally formed with the first side stop portion 1232. Of course, the multiple second side stop portions 1233 can also be separately formed with the first side stop portion 1232, such as the multiple second side stop portions 1233 can be respectively screwed on the multiple edges of the first side stop portion 1232; the multiple second side stop portions 1233 can also be respectively clamped on the multiple edges of the first side stop portion 1232. In this regard, the embodiment of the present application is not limited. In an achievable method provided in the embodiment of the present application, the multiple second side stop portions 1233 are integrally formed with the first side stop portion 1232. In this way, the later installation time is saved while ensuring the reliability of the connection.

[0060] The cart provided in the embodiment of the present application forms the second accommodating portion 1231 by recessing one or both sides of the second side stop portion 1233 and the corresponding first side stop portion 1232. This method has the advantages of simplicity and convenience.

[0061] The embodiment of the present application provides a cart, wherein at least one of the plurality of second side stoppers 1233 is provided with a handle.

[0062] In one example, the surface roughness of the handle portion may be greater than the surface roughness of other positions of the second side stop portion 1233. Specifically, anti-slip grooves may be provided on the handle portion to prevent slipping. In another example, the surface of the handle portion is a curved surface to facilitate fitting with the user's palm.

[0063] The cart provided in the embodiment of the present application is provided with a handle on at least one second side stopper 1233, so that the cart can be easily transported and pushed and pulled.

[0064] The present application embodiment provides a cart, please refer to Figure 5 or Figure 7 , along the first direction A, the size of the second receiving portion 1231 is larger than the size of the roller 121 .

[0065] Here, it needs to be explained that, along the first direction A, the size of the second receiving portion 1231 can also be referred to as the depth size of the second receiving portion.

[0066] The cart provided in the embodiment of the present application can limit the size of the second accommodating portion 1231 and the roller along the first direction A, so that the roller 121 of the upper cart can be completely embedded in the second accommodating portion 1231 of the lower cart.

[0067] The present application embodiment provides a cart, please refer to Figure 4The inner contour of the second accommodating portion 1231 includes an arc segment 12311 and an open segment 12312 . The arc segment 12311 is adapted to the outer contour of the roller 121 , and the size of the open segment 12312 is greater than or equal to the maximum size of the arc segment 12311 .

[0068] In the cart provided in the embodiment of the present application, the arc segment 12311 is adapted to the outer contour of the roller 121, so that the overall consistency of the cart can be improved. On this basis, the size of the open section 12312 is greater than or equal to the maximum size of the arc segment 12311, which can facilitate the roller 121 of the cart located above to smoothly enter the second accommodating portion 1231 of the cart below.

[0069] The present application embodiment provides a cart, please refer to Figure 1 The bottom support member 122 is provided with a plurality of first ventilation grooves 1221, the first ventilation grooves 1221 are used to allow air to pass through, and the width of the first ventilation grooves 1221 is greater than the width of the object 2 to be dried; and / or the side stopper 123 is provided with a plurality of second ventilation grooves 1234, the second ventilation grooves 1234 are used to allow air to pass through, and the width of the second ventilation grooves 1234 is less than the width of the object 2 to be dried.

[0070] In the embodiment of the present application, a plurality of first air permeable grooves 1221 may be provided only on the bottom support member 122; a plurality of second air permeable grooves 1234 may be provided only on the side stop member 123; a plurality of first air permeable grooves 1221 may also be provided on the bottom support member 122, and a plurality of second air permeable grooves 1234 may also be provided on the side stop member 123 at the same time, and the embodiment of the present application does not impose any limitation on this.

[0071] In the embodiment of the present application, the shapes of the first air permeable groove 1221 and the second air permeable groove 1234 can be the same, such as both are long strips. The shapes of the first air permeable groove 1221 and the second air permeable groove 1234 can also be different, such as the first air permeable groove 1221 is a long strip and the second air permeable groove 1234 is circular. This is also not limited to the embodiment of the present application.

[0072] In the cart provided in the embodiment of the present application, since the first ventilation groove 1221 is used to allow air to pass through, the heat below the bottom support member 122 can be easily transferred from the first ventilation groove 1221 to the first accommodation portion, so that the objects to be dried 2 located in the first accommodation portion are heated, thereby improving the heating uniformity of the objects to be dried 2. On this basis, the width of the first ventilation groove 1221 is greater than the width of the objects to be dried 2, so as to prevent the objects to be dried 2 from falling out of the first ventilation groove 1221.

[0073] In the cart provided in the embodiment of the present application, since the second ventilation groove 1234 is used to allow air to pass through, the heat on the side wall of the side stopper 123 can be easily transferred from the second ventilation groove 1234 to the first accommodating portion, so that the objects to be dried 2 located in the first accommodating portion are heated, thereby improving the heating uniformity of the objects to be dried 2. On this basis, the width of the second ventilation groove 1234 is smaller than the width of the objects to be dried 2, so as to prevent the objects to be dried 2 from falling from the second ventilation groove 1234.
