[0038] Embodiment 1

[0039] Please refer to the attached Figure 1 To Attachment Figure 8An embodiment of the present invention provides a quick-plug fixing structure of an electronic scale, including a first module 1 and a second module 2, wherein the first module 1 and the second module 2 are respectively provided with a plug connector 3 and a socket connector 4 that match each other, and the plug connector 3 is provided with a first electrical connector 5, and the socket connector 4 is provided with a second electrical connector 6 that matches the first electrical connector 5, the first module 1 and the second module 2 are configured to be connected together by plugging and matching the plug connector 3 and the socket connector 4, while the first electrical connector 5 and the second electrical connector 6 can be aligned and matched together to achieve electrical connection, and a fastener 7 that can directly fasten and lock the first module 1 and the second module 2 together is also provided between the first module 1 and the second module 2.

[0040] This embodiment is described by taking a modular electronic scale as an example. Figure 1 As shown, the first module 1 is the main body of the electronic scale with a touch screen control pole, and the second module 2 is the main body of the electronic scale pan. However, those skilled in the art should understand that in other embodiments, the first module 1 can also be the main body of the electronic scale pan, and correspondingly, the second module 2 is the main body of the electronic scale with a touch screen control pole. In addition, the first module 1 and the second module 2 can also be other electronic devices that need to be assembled together modularly, such as the assembly of a display screen and a base body, etc. The plug connector 3 is arranged on the first module 1, and the socket 4 is correspondingly arranged on the second module 2. However, those skilled in the art should understand that in other embodiments, the arrangement positions of the plug connector 3 and the socket 4 can also be reversed, for example, the socket 4 is arranged on the first module 1, and the plug connector 3 is arranged on the second module 2. In this embodiment, the first electrical connector 5 and the second electrical connector 6 are respectively one of the male head and the female socket, and the connection direction between the male head and the female socket is the same as the plug-in matching direction of the plug connector 3 and the socket 4.

[0041] When assembling the first module 1 and the second module 2, the plug-in fitting of the plug connector 3 and the socket connector 4 respectively arranged on the first module 1 and the second module 2 can realize the precise alignment of the first module 1 and the second module 2 and realize the mechanical fixed connection, and because the first electrical connector 5 is provided in the plug connector 3, and the second electrical connector 6 adapted to the first electrical connector 5 is provided in the socket connector 4, when the socket connector 4 and the plug connector 3 are precisely plugged together, the first electrical connector 5 and the second electrical connector 6 can also complete the alignment and contact together with the plug-in action of the plug connector 3 and the socket connector 4 to realize electrical connection, and by the first module 1 and the second module 2, the first electrical connector 5 and the second electrical connector 6 can be connected to each other and realize electrical connection. A fastener 7 is provided between the two modules 2, which can directly fasten and lock the first module 1 and the second module 2 together. The fastener 7 is locked from the side of the first module 1 and directly locks the first module 1 and the second module 2 together. Compared with the locking method in the prior art CN209747873U in which the guide member is confined in the guide hole by a fastener (screw or fixing pin) so that the corresponding base body and the display screen are locked together, the fastener 7 of this embodiment directly acts on the first module 1 and the second module 2. Therefore, the locking firmness of the first module 1 and the second module 2 is greatly improved, thereby ensuring the firmness and stability of the product.

[0042] Please refer to the attached Figure 1 , Attachment Figure 6 To Attachment Figure 8 In one preferred embodiment, preferably, the fastener 7 is a screw, and the first module 1 and the second module 2 are respectively provided with a screw mounting hole 11 and a screw locking hole 21 which are arranged corresponding to each other, and the screw as the fastener 7 is configured to be able to penetrate the screw mounting hole 11 and correspondingly lock into the screw locking hole 21, thereby firmly locking the first module 1 and the second module 2 together. However, it should be understood by those skilled in the art that in other embodiments, the screw as the fastener 7 can also be driven into the side of the second module 2 and penetrate the second module 2 to be locked to the first module 1, thereby firmly locking the second module 2 and the first module 1 together, and is not limited to the specific embodiment disclosed in this embodiment. In this embodiment, in order to better ensure the locking firmness of the first module 1 and the second module 2, two dispersedly arranged fasteners 7 are arranged between the first module 1 and the second module 2. However, those skilled in the art should understand that in other embodiments, other numbers of fasteners 7 may be arranged between the first module 1 and the second module 2 to lock the first module 1 and the second module 2 together. It is not limited to the specific implementation method disclosed in this embodiment, as long as the first module 1 and the second module 2 can be firmly locked together.

[0043] Please refer to the attached Figure 1 , Attachment Figure 6 To Attachment Figure 8In one preferred embodiment, a screw anti-slip stop cover 8 located in the withdrawal direction of the fastener 7 is detachably installed on the first module 1 having a screw mounting hole 11, and an operating hole is provided on the screw anti-slip stop cover 8 corresponding to the nut end of the fastener 7, and the aperture of the operating hole is slightly smaller than the outer diameter of the nut end of the fastener 7, and the distance between the screw anti-slip stop cover 8 and the first module 1 is smaller than the length of the screw. It is understandable that in this embodiment, by installing a screw anti-dropout stop cover 8 on the first module 1 to prevent the fastener 7 (screw) from falling out of the screw mounting hole 11 on the first module 1, and by configuring the distance between the screw anti-dropout stop cover 8 and the first module 1 to be smaller than the length of the screw, after the screw anti-dropout stop cover 8 is installed on the first module 1, the fastener 7 can only be connected to the screw mounting hole 11 of the first module 1, so that the fastener 7 can only be extended and retracted in and out of the screw mounting hole 11, or locked into the screw locking hole 21 of the second module 2 to lock the first module 1 and the second module 2 together, or withdrawn from the screw locking hole 21 to separate the first module 1 and the second module 2. In addition, an operating hole corresponding to the nut end of the fastener 7 is provided on the screw anti-dropout stop cover 8, and a wrench can be inserted through the operating hole to be embedded in the nut end of the fastener (screw) and then the fastener 7 can be screwed, without removing the screw anti-dropout stop cover 8.

[0044] Please refer to the attached Figure 1 To Attachment Figure 8 In one preferred embodiment, the locking direction of the fastener 7 is parallel to the plug-in matching direction of the socket 4 and the plug connector 3. It can be understood that in this embodiment, since the locking direction of the fastener 7 is configured to be parallel to the plug-in matching direction of the plug connector 3 and the socket 4, after the plug connector 3 of the first module 1 and the socket 4 of the second module 2 are accurately aligned and plugged together, the fastener 7 on the first module 1 will correspond to the screw locking hole 21 on the second module 2, and then the wrench can be inserted through the operating hole on the screw anti-slip stop cover 8 to screw the fastener 7 so that the head end of the fastener 7 is locked into the screw locking hole 21 of the second module 2, thereby locking the first module 1 and the second module 2 together. The locking process is simple and fast, and the firmness is good, which can well ensure the matching stability of the plug connector 3 and the socket 4 and the first electrical connector 5 and the second electrical connector 6.

[0045] Please refer to the attached Figure 2 To Attachment Figure 5In one preferred embodiment, a sealing ring 9 is provided between the first module 1 and the second module 2 to improve the sealing performance of the plug-in fitting of the plug connector 3 and the socket connector 4. Preferably, the sealing ring 9 is embedded in the first module 1 and is located on the abutting fitting surface of the first module 1 and the second module 2, and the sealing ring 9 surrounds the outer peripheral position of the plug connector 3. By installing a sealing ring 9 at the outer peripheral position of the plug-in fitting of the plug connector 3 and the socket connector 4, the sealing performance of the plug-in fitting of the plug connector 3 and the socket connector 4 can be well ensured, so that the plug-in fitting of the plug connector 3 and the socket connector 4 can form a closed chamber inside to prevent water vapor from entering, thereby ensuring the electrical safety of the first electrical connector 5 and the second electrical connector 6 arranged inside the plug connector 3 and the socket connector 4.

[0046] Please refer to the attached Figure 6 , Attachment Figure 7 In one preferred embodiment, an internal thread structure (not shown) is provided in the screw mounting hole 11, the fastener 7 is screwed in the screw mounting hole 11, and an internal thread structure is provided inside the screw locking hole 21, so that the head end of the fastener 7 can form a threaded connection with the screw locking hole 21. It can be understood that by providing an internal thread structure in the screw mounting hole 11, the fastener 7 is screwed in the screw mounting hole 11. Such a design can effectively improve the connection stability between the fastener 7 and the first module 1, avoid displacement deviation, and also improve the connection reliability between the first module 1 and the second module 2 to a certain extent. However, those skilled in the art should understand that in some other embodiments, the screw mounting hole 11 can also be other types of mounting hole structures, and is not limited to the specific implementation methods disclosed in this embodiment. For example, the screw mounting hole 11 can also be a straight hole structure with a smooth inner wall, and the inner diameter of the straight hole is adapted to the outer diameter of the fastener 7. When fastening, the first module 1 and the second module are locked together by the pressing action of the nut end of the fastener 7 (screw).

[0047] Please refer to the attached Figure 1 In one preferred embodiment, the screw locking hole 21 is defined as having an outer half section close to the outer side and an inner half section close to the inner side, the outer half section of the screw locking hole 21 is a straight hole structure with a smooth inner wall, and the inner half section of the screw locking hole 21 is a threaded hole structure with an inner thread on the inner wall. It can be understood that by setting the outer half section of the screw locking hole 21 on the second module 2 to have a straight hole structure with a smooth inner wall, when the first module 1 and the second module 2 are precisely aligned and matched together through the plug-in matching of the socket 4 and the plug-in 3, the head end of the screw as the fastener 7 can cooperate with the straight hole structure of the outer half section of the screw locking hole 21 to form a rough positioning, so that when the head of the screw can enter the screw locking hole 21 more smoothly, the screw can be continuously screwed to lock its head into the threaded hole structure of the inner half section of the screw locking hole 21, thereby locking the first module 1 and the second module 2 together.

[0048] In addition, the socket 4 in this embodiment is a square convex rib structure protruding to the side relative to the second module 2, and the plug connector 3 is a socket structure recessed inwardly relative to the side of the first module 1, and the square convex rib is configured to be able to be inserted and embedded into the socket structure and form an interference fit so that the first module 1 and the first module are mechanically fixedly connected together. However, those skilled in the art should understand that in other embodiments, the socket 4 and the plug connector 3 can also be other types of plug-in connection structures, for example, the corresponding plug-in matching connection structure in the prior art CN209747873U can be referred to, and the first electrical connector 5 and the second electrical connector 6 can also be designed with reference to the corresponding electrical connection structure in CN209747873U, and are not limited to the specific implementation methods disclosed in this embodiment.

[0049] Please refer to the attached Figure 1 An embodiment of the present invention further provides an electronic scale, comprising the quick-insert fixing structure of the electronic scale of any of the above embodiments.

[0050] Embodiment 2

[0051] Please refer to the attached Fig. 9 To Attachment Fig.16 The difference between this embodiment and the first embodiment is that the screw locking hole 21 is a stepped hole structure with a large outer portion and a small inner portion, and the screw locking hole 21 has a large hole portion 211 and a small hole portion 212. A pre-positioning sleeve 71 capable of being adapted and embedded in the large hole portion 211 of the screw locking hole 21 is connected at the head end position of the screw passing through the screw mounting hole 11. The pre-positioning sleeve 71 can cooperate with the large hole portion 211 of the screw locking hole 21 to achieve pre-alignment and alignment of the first module 1 and the second module 2, and the screw is configured to be able to continue to be screwed into the small hole portion 212 of the screw locking hole 21 by screwing and be threadedly connected with the small hole portion 212, thereby firmly locking the first module 1 and the second module 2 together by the screw. In this embodiment, preferably, the pre-positioning sleeve 71 is configured to be detachably screwed to the head end position of the fastener 7 (screw) passing through the screw mounting hole 11 through a threaded connection structure. However, those skilled in the art should understand that in other embodiments, the pre-positioning sleeve 71 may also be coaxially arranged with the screw mounting hole 11 of the first module 1 and directly fixedly connected to the side of the first module 1 (not shown) or integrally formed with the side of the first module 1 (not shown), as long as during the alignment process of the first module 1 and the second module 2, the pre-positioning sleeve 71 can be adapted and nested with the large hole portion 211 of the screw locking hole 21 on the second module 2 to form a pre-positioning structure, and is not limited to the specific implementation method disclosed in this embodiment.

[0052] Please refer to the attached Fig. 9 To Attachment Fig.16It can be understood that, in the present embodiment, a pre-positioning sleeve 71 is threadedly connected at the head end position of the screw as the fastener 7 passing through the screw mounting hole 11 of the first module 1, and the pre-positioning sleeve 71 protrudes relatively to the side relative to the first module 1, and the pre-positioning sleeve 71 is configured to be able to be non-rotatably adapted to be embedded in the large hole portion 211 of the screw locking hole 21 of the second module 2, thereby performing more accurate pre-positioning and correction of the first module 1 and the second module 2, so that the plug-in connector 3 and the socket connector 4 on the first module 1 and the second module 2 can be more conveniently plugged and matched together, thereby performing multiple alignment of the first module 1 and the second module 2, thereby ensuring the accuracy of the alignment and matching of the first electrical connector 5 and the second electrical connector 6. At the same time, since the pre-positioning sleeve 71 protrudes outward to the side relative to the first module 1, the operator can easily observe the alignment of the pre-positioning sleeve 71 and the screw locking hole 21 of the second module 2 with the help of its protruding part, which is conducive to improving the convenience of the alignment operation of the first module 1 and the second module 2 and improving its assembly efficiency. In this embodiment, specifically, the length of the pre-positioning sleeve 71 can be set to be compatible with or slightly smaller than the hole depth of the large hole portion 211 of the screw locking hole 21, so that during the alignment and assembly process of the first module 1 and the second module 2, the pre-positioning sleeve 71 can be completely embedded in the large hole portion 211 of the screw locking hole 21, and then the matching mounting surfaces of the first module 1 and the second module 2 can be closely fitted to ensure the assembly stability of the two. In order to improve the embedding smoothness of the pre-positioning sleeve 71, those skilled in the art should understand that the head position of the pre-positioning sleeve 71 can also be rounded so that it can be more smoothly embedded in the large hole portion 211 of the screw locking hole 21. When the first module 1 and the second module 2 are docked in place (the pre-positioning sleeve 71 is completely embedded in the large hole portion 211, the plug-in connector 3 and the socket connector 4 and the first electrical connector 5 and the second electrical connector 6 between the first module 1 and the second module 2 are aligned and matched together respectively, and the sides of the first module 1 and the second module 2 are close together), the fastener 7 can be screwed so that its head can be screwed into the small hole portion 212 of the screw locking hole 21 of the second module 2 and form a threaded connection with the small hole portion 212, thereby firmly locking the first module 1 and the second module 2 together. Therefore, it can be understood that by adding a pre-positioning sleeve 71 at the position of the screw head, it not only has the locking function of locking the first module 1 and the second module 2, but also can form a pre-positioning function through the cooperation of the pre-positioning sleeve 71 and the large hole portion 211 of the screw locking hole 21, so as to improve the simplicity of the alignment operation and the alignment accuracy of the first module 1 and the second module 2, which is conducive to improving the user experience and enhancing the market competitiveness of the product.

[0053] Please refer to the attached Fig. 9 To Attachment Fig.16In this embodiment, preferably, the pre-positioning sleeve 71 has a non-circular shape, and specifically, it can be as shown in the attached Fig.10 The square structure shown, correspondingly, the cross-section of the large hole portion 211 of the screw locking hole 21 on the second module 2 is a square hole structure that is compatible with the outer dimensions of the pre-positioning sleeve 71 of the square structure. However, those skilled in the art should understand that in other embodiments, the outer structure of the pre-positioning sleeve 71 is not limited to the specific implementation manner disclosed in this embodiment, and may also be other non-circular structures, such as triangles or ellipses or multiple deformations, as long as the pre-positioning sleeve 71 can be non-rotatably adapted and nested in the large hole portion 211 of the screw locking hole 21 to form a pre-positioning structure that can accurately pre-position the first module 1 and the second module 2. In addition, since the pre-positioning sleeve 71 of this embodiment is screwed at the head position of the fastener 7, a limiting structure (such as a positioning groove or a positioning convex rib structure that matches the outer dimensions of the pre-positioning sleeve 71) can be set on the side of the first module 1 to prevent the pre-positioning sleeve 71 connected to the head position of the fastener 7 (screw) from rotating, so as to further improve the convenience and accuracy of the alignment between the pre-positioning sleeve 71 and the large hole portion 211 of the screw locking hole. Furthermore, in order to ensure that the pre-positioning sleeve 71 connected to the head position of the fastener 7 has good positioning firmness, in this embodiment, as shown in the attached Fig.14 As shown, an internal thread structure can be provided inside the screw mounting hole 11 of the first module 1, so that the screw as the fastener 7 is screwed into the screw mounting hole 11 of the first module 1. Such a design can ensure that the pre-positioning sleeve 71 can be relatively firmly connected to the first module 1 without moving forward and backward or shifting left and right relative to the first module 1, which is conducive to improving the alignment accuracy of the first module 1 and the second module 2. However, those skilled in the art should understand that in other embodiments, the outer structure of the pre-positioning sleeve 71 can also be circular (not shown in the figure). In this case, the pre-positioning sleeve 71 can be configured to be movably sleeved on the head end position of the fastener 7 (screw) passing through the screw mounting hole 11 in a small clearance sliding fit manner, and the large hole portion 211 of the screw locking hole 21 on the second module 2 is a circular hole, and the aperture of the circular hole is adapted to the outer diameter of the pre-positioning sleeve 71, so that the pre-positioning sleeve 71 can be adaptively embedded in the large hole portion 211 of the screw locking hole 21 on the second module 2 to play a pre-positioning role.

[0054] As described above, the embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements do not deviate the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention. Therefore, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.
