Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation, and in particular to a connector, a heating device, and a container. Background Technology

[0002] Medium-sized bulk containers, due to their strong corrosion resistance, are widely used in chemical plants to store highly corrosive, flammable, and volatile liquid chemical raw materials, thus requiring high safety performance. These containers are lined with inner bags to hold the liquid. Currently, one method for heating the liquid inside the liner is electric heating. Before filling, the heating element is placed at the bottom inside the container, connected via a separate connector. The connection is plug-in type; simply insert the power cord into the device's power interface to connect the power supply. Considering electrical safety factors such as moisture and dust entering the power interface and the easy unplugging of the power cord, two plug-in connection methods are currently available on the market: threaded locking mechanism and push-button locking mechanism. However, threaded connections require separate thread tightening before and after plugging and unplugging, resulting in high connection strength but low efficiency. Push-button locking mechanisms, on the other hand, result in uneven force on the plug after connection, leading to low connection strength. Utility Model Content

[0043] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0044] The first embodiment of this utility model relates to a connector 101. For example... Figure 1 , Figure 2 , Figure 3 As shown, connector 101 includes: a first plug-in terminal 1, an externally connected second plug-in terminal 2, a connecting wire 3 connecting the first plug-in terminal 1 and the second plug-in terminal 2, a locking member 4 hinged to the first plug-in terminal 1, and an elastic member 5. The elastic member 5 can be a spring, with its two ends abutting against one end of the locking member 4 and the first plug-in terminal 1, respectively. The first plug-in terminal 1 and the locking member 4 can be inserted into the heating element 102, and the second plug-in terminal 2 can be connected to an external power source. The elastic member 5 applies a squeezing force to one end of the locking member 4, pushing the other end of the locking member 4 toward the first plug-in terminal 1. When the end of the locking member 4 abutting against the elastic member 5 is pressed against the elastic member 5 by an external force, the end of the locking member 4 away from the elastic member 5 opens at a preset angle with the first plug-in terminal 1.

[0045] like Figure 1 , Figure 2 , Figure 4 , Figure 10 As shown, connector 101 can be used to form a heating device 100 on heating element 102. Heating element 102 is laid inside the box 200 of container 1000 and can heat the inner liner bag placed inside the box 200. Connector 101 and heating element 102 are detachably connected. Heating element 102 has an electrical connection end with a power interface 80. Heating element 102 also has a locking slot 81. The first plug end 1 is inserted into the power interface 80, and the other end of the locking member 4 is inserted into the locking slot 81. The other end of the locking member 4 is locked into the locking slot 81 under the squeezing and pushing force of elastic member 5. Figure 5 , Figure 8 , Figure 9 As shown, Figure 8 F1 indicates the pressure applied. Figure 9 F2 is the force exerted by the elastic force of the elastic element on the locking element around the cylindrical pin. When it is necessary to connect the connector 101 to the heating element 102, the locking element 4 can be pressed. After the end of the locking element 4 connected to the elastic element 5 is pressed, it moves closer to the first plug end 1. The angle between the other end of the locking element 4 and the first plug end 1 becomes larger. At the same time as the first plug end 1 is inserted into the power interface 80, the other end of the locking element 4 is also inserted into the locking hole 81. Then the locking element 4 is released. Under the action of the squeezing force of the elastic element 5, the angle between the other end of the locking element 4 and the first plug end 1 becomes smaller, and the locking element 4 is locked in the locking hole 81.

[0046] As can be seen from the above, by setting the locking member 4 to be hinged to the first plug end 1, and the two ends of the elastic member 5 abutting against the first plug end 1 and the locking member 4 respectively, when the first plug end 1 is connected to the heating element 102, the locking member 4 can be pressed to lock the end of the locking member 4 facing the heating element 102 into the heating element 102 at the same time. This allows the connector 101 and the heating element 102 to be detachably connected, while also making the connection between the heating element 102 and the connector 101 high in strength and efficiency, and safer and more convenient to use.

[0047] Furthermore, such as Figure 3 As shown, the end of the first plug-in terminal 1 facing away from the connecting wire 3 has an electrical connection hole 10, and the end of the locking member 4 facing the electrical connection hole 10 has a locking hook 41. Figure 5 As shown, the locking hook 41 has a hook body surface 411 and an extension surface 412 connected to the hook body surface 411. The hook body surface 411 and the extension surface 412 constitute the first locking hook 41 section. The included angle α between the hook body surface 411 and the extension surface 412 is an acute angle, which can more firmly lock the locking hook 41 heating element 102 during the connection process.

[0048] Furthermore, such as Figure 3 , Figure 9As shown, the first connector 1 includes a first connector portion 11 with an electrical connection hole 10, and a first connector body portion 12 connected to the first connector portion 11 and the connecting wire 3. A locking member 4 is connected to the first connector body portion 12 via a cylindrical pin 7, and the locking member 4 can rotate around the cylindrical pin 7. The connector 101 also includes a sealing member 6, which is sleeved on the end of the first connector portion 11 connected to the first connector body portion 12. This sealing member 6 is a sealing ring. After the first connector portion 11 is locked to the power interface 80 of the heating element 102, the sealing member 6 is compressed, filling the gap between the first connector portion 11 and the power interface 80, thereby achieving waterproofing and dustproofing.

[0049] Furthermore, such as Figure 8 , Figure 9 As shown, the locking element 4 and the elastic element 5 constitute a locking device, which is a pair, with the first insertion end 1 located between the pair of locking devices. When the locking element 4 is inserted into the locking port 81, the locking elements 4 on both sides are compressed by the elastic force of the elastic element 5. The elastic force is applied to the locking port 81 around the cylindrical pin 7, and the force is evenly distributed, which prevents pull-out. Through the double-sided locking device, the connector 101 and the heating element 102 can be locked and unlocked, and the connector 101 is evenly stressed and the connection is stable during use.

[0050] The second embodiment of this utility model relates to a heating device 100. For example... Figure 1 , Figure 2 , Figure 4 As shown, the heating device 100 includes a heating element 102 and a connector 101 as described in the above embodiment. The heating element 102 has a power interface 80 and a locking slot 81 located on the side of the power interface 80. When the first insertion end 1 of the connector 101 is inserted into the power interface 80, the other end of the locking member 4 is inserted into the locking slot 81, and the other end of the locking member 4 is locked into the locking slot 81 under the squeezing and pushing force of the elastic member 5.

[0051] Furthermore, such as Figure 5 , Figure 6 , Figure 8 As shown in Figures 9 and 1, the side wall 811 of the lock opening 81 has a protrusion 9, and the protrusion 9 and the side wall 811 therein form the second lock hook 41 interval into which the lock hook 41 of the lock fastener 4 is inserted, and the protrusion 9 is used to insert into the first lock hook 41 interval of the lock fastener 4.

[0052] Furthermore, such as Figure 6 , Figure 7 , Figure 8As shown, the protrusion 9 has an abutment surface 91, which faces the bottom surface of the lock opening 81. The abutment surface 91 is adjacent to the side wall 811 where the protrusion 9 is located, and the included angle b between the abutment surface 91 and the side wall 811 where the protrusion 9 is located is an acute angle. When the first plug-in end 1 is inserted into the power interface 80 and the locking member 4 is inserted into the lock opening 81, the acute angle b allows the locking member 4 to better engage with the protrusion 9, preventing slippage during the connection process.

[0053] In addition, such as Figure 7 , Figure 8 As shown, the protrusion 9 has a guide surface 92, which is an inclined surface. The guide surface 92 is disposed away from the bottom surface of the locking slot 81 and extends obliquely toward the opening of the locking slot 81 towards the power interface 80. By providing the guide surface 92, the connector 101 can be guided to quickly connect to the power interface 80.

[0054] In addition, such as Figure 8 , Figure 9 As shown, due to the presence of the sealing element 6, when the first plug end 11 is inserted into the power interface 80, the sealing element 6 fills the gap between the first plug end 1 and the power interface 80.

[0055] The specific operating steps for inserting connector 101 into heating element 102 are as follows: First, press the locking parts 4 on both sides of the plug with your fingers. At this time, the elastic element 5 is compressed, and the locking parts 4 are fully opened. Second, push the first plug end 1 of connector 101 into the power interface 80 after it is opened. Third, release the locking parts 4. Under the elastic force of the elastic element 5, the locking parts 4 on both sides are squeezed by the elastic force of the elastic element 5, tightly locking the power interface 80. The force is evenly distributed. At this time, the sealing element 6 is squeezed, filling the gap between the first plug end 1 and the power interface 80. This structure serves to prevent dust and water damage and prevent pull-out.

[0056] In addition, such as Figure 1 As shown, the heating device 100 also includes: a lifting strap 103 connected to the heating element 102, and a buckle 104 disposed at one end of the lifting strap 103 opposite to the heating element 102. The lifting strap 103 and the power interface 80 are respectively located at both ends of the heating element 102. After the connector 101 is connected to the heating element 102, the connecting line 3 extends from inside the housing 200 to outside the housing 200, allowing the second plug-in end 2 to extend outside the housing 200.

[0057] It is not difficult to see that this embodiment is a system implementation corresponding to the first embodiment, and this embodiment can be implemented in conjunction with the first embodiment. The relevant technical details mentioned in the first embodiment are still valid in this embodiment, and will not be repeated here to reduce repetition. Accordingly, the relevant technical details mentioned in this embodiment can also be applied to the first embodiment.

[0058] The third embodiment of this utility model relates to a container 1000. For example... Figure 10 , Figure 11 As shown, the container 1000 includes a housing 200 and a heating device 100 as described in the above embodiment. The heating element 102 of the heating device 100 is disposed inside the housing 200, and the heating pad can be used to heat the inner lining bag placed inside the housing 200. After the connector 101 is connected to the heating element 102, the connecting line 3 extends from inside the housing 200 to outside the housing 200, allowing the second plug-in end 2 to extend outside the housing 200.

[0059] Furthermore, such as Figure 10 , Figure 11 As shown, a discharge port 201 is provided on the wall of the housing 200. The heating device 100 also includes a lifting strap 103 connected to the heating element 102, and a fastener 104 disposed at the end of the lifting strap 103 opposite to the heating element 102. The fastener 104 is engaged in the discharge port 201, which is used to connect to the outlet end of the inner lining bag for discharge. The side of the fastener 104 has a retaining piece 1041, which can be an elastic thin sheet or an integral part of the fastener 104. When the fastener 104 is inserted into the discharge port 201, the retaining piece 1041 abuts against the side of the discharge port 201. The retaining piece 1041 is squeezed and applies a spring-like pushing force to the side of the discharge port 201, thereby positioning the fastener 104 with the lifting strap 103 in the discharge port 201, so that the heating device 100 can be positioned inside the housing 200.

[0060] It is not difficult to see that this embodiment is a system implementation corresponding to the second embodiment, and this embodiment can be implemented in conjunction with the second embodiment. The relevant technical details mentioned in the second embodiment are still valid in this embodiment, and will not be repeated here to reduce repetition. Accordingly, the relevant technical details mentioned in this embodiment can also be applied to the second embodiment.

[0061] The preferred embodiments of the present invention have been described in detail above, but it should be understood that, if necessary, aspects of the embodiments can be modified to utilize aspects, features, and concepts from various patents, applications, and publications to provide other embodiments.

[0062] In light of the detailed description above, these and other changes can be made to the embodiments. Generally, the terminology used in the claims should not be considered limited to the specific embodiments disclosed in the specification and claims, but should be understood to include all possible embodiments together with the full scope of equivalents enjoyed by these claims.

[0063] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
