[0040] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0042] Combination Figure 1-7 As shown, an embodiment of the present disclosure provides a positioning device for a door body, including a fixing member 1 and a positioning member 2.

[0043] like Figure 1-4 As shown, one end of the fixing member 1 can be adsorbed onto the outer surface of the door body 3, so as to fix the positioning device to the door body 3; the positioning member 2 is connected to the other end of the fixing member 1, and is configured to be arranged at the intersection of the gaps between the multiple door bodies 3, and to fit into the corners of the multiple door bodies 3, so as to limit the gap distance between the multiple door bodies 3.

[0044] By using the positioning device provided by the embodiment of the present invention, when the fixing member 1 is adsorbed onto the door body 3, the fixing member 1 fits against the outer surface of the door body 3, so that the positioning device can be fixed to the door body 3, and the position of the positioning device relative to the door body 3 can be adjusted. The positioning member 2 fits against the corners of multiple door bodies 3, and the gaps between the multiple door bodies 3 are distributed along the position of the positioning member 2, so as to limit the gap distance and gap position between each door body 3, and then the door body 3 is installed. In this way, compared with the related art, the fixing member 1 can be adsorbed onto door bodies 3 of different thicknesses, and the positioning member 2 can be arranged in the gap between door bodies 3 of different thicknesses. The positioning device can be applicable to door bodies 3 of different thicknesses, thereby expanding the scope of use of the positioning device.

[0045] The fixing part 1 is adsorbed onto the outer surface of the door body 3, so that there is an adsorption force between the fixing part 1 and the door body 3. The fixing part 1 and the door body 3 are relatively fixed, and can also move up, down, left and right along the outer surface of the door body 3 in the adsorption state. During the movement, the corners of multiple door bodies 3 are more closely fitted to the positioning part 2, so that the gap distance between the multiple door bodies 3 is more standard, and the subsequent installation of the door body 3 is more accurate.

[0046] The following embodiments illustrate the structure of the positioning device in combination with the matching state of the positioning device with the door body when the positioning device is applied to the door body assembly.

[0047] Alternatively, if Figure 2 and Figure 4 As shown, the positioning member 2 includes a main body 21 and a first connecting portion 22. The main body 21 is cross-shaped and is configured to be arranged in the gap between four door bodies 3. The four door bodies 3 are arranged in the up, down, left and right directions; the first connecting portion 22 is connected to the main body 21 and to the fixing member 1.

[0048] The main body 21 of the positioning member 2 is arranged in the gap between the four door bodies 3. The main body 21 is cross-shaped. The four door bodies 3 are arranged in the up, down, left and right directions. The corners of the four door bodies 3 close to the main body 21 of the positioning member 2 are in contact with the main body 21 of the positioning member 2. The gap distance and gap position between any two of the four door bodies 3 are determined by the main body 21 of the positioning member 2. The gap is distributed along the distribution of the positioning member 2. The first connecting portion 22 is connected to the main body 21 and to the fixing member 1. The setting of the first connecting portion 22 connects the fixing member 1 with the positioning member 2. The fixing member 1 and the door bodies 3 are adsorbed, which plays a fixing role between the positioning device and the door bodies 3. The main body 21 in the positioning member 2 is arranged in the gap between the door bodies 3, which plays a role in limiting the position of the door bodies 3. The first connecting portion 22 in the positioning member 2 plays a connecting role. The main body 21 cooperates with the first connecting portion 22, and the positioning member 2 cooperates with the fixing member 1, which together play a positioning role for the installation of the four door bodies 3.

[0049] Alternatively, if Figure 5 As shown, the main body 21 includes a first section 211, a second section 212, a third section 213 and a fourth section 214. The first section 211 can be set in the gap between the first door body 31 and the second door body 32; the second section 212 can be set in the gap between the second door body 32 and the third door body 33; the third section 213 can be set in the gap between the third door body 33 and the fourth door body 34, and is set opposite to the first section 211; the fourth section 214 can be set in the gap between the fourth door body 34 and the first door body 31, and is set opposite to the second section 212; wherein, the first section 211, the second section 212, the third section 213 and the fourth section 214 are intersected and connected, and their intersecting connection positions correspond to the intersections of the gaps between the first to fourth door bodies 34.

[0050] The main body 21 is cross-shaped, and each section of the main body 21 is respectively arranged in the gap formed by the two adjacent door bodies 3. The first door body 31 is located between the first section 211 and the second section 212, and the first section 211 and the second section 212 are respectively fitted with the two side walls of the corner of the first door body 31. The second door body 32 is located between the second section 212 and the third section 213, and the second section 212 and the third section 213 are respectively fitted with the two side walls of the corner of the second door body 32. The third door body 33 is located between the third section 213 and the fourth section 214, and the third section 213 and the fourth section 214 are respectively fitted with the third door body 33. The two side walls of the corner are fitted together, and the fourth door body 34 is located between the fourth section 214 and the first section 211. The fourth section 214 and the first section 211 are respectively fitted with the two side walls of the corner of the fourth door body 34. The first section 211, the second section 212, the third section 213 and the fourth section 214 are intersected and connected at the intersection of the gaps between the first to fourth door bodies 34. In this way, the first section 211, the second section 212, the third section 213 and the fourth section 214 cooperate with each other to determine the gap distance and gap position between the first door body 31, the second door body 32, the third door body 33 and the fourth door body 34.

[0051] Alternatively, if Figure 6 and Figure 7 As shown, the first section 211 and the fourth section 214 both include a main body 215 and an extension portion 216, the main body 215 is arranged inside the gap; the extension portion 216 is connected to the main body 215 and is arranged outside the gap; wherein, the first connecting portion 22 is arranged between the extension portion 216 of the first section 211 and the extension portion 216 of the fourth section 214, and when the fixing member 1 is adsorbed on the outer surface of the door body 3, the first connecting portion 22 is parallel to the outer surface of the first door body 31 and is connected to the other end of the fixing member 1.

[0052] The above embodiment mentioned that the first connection part 22 of the positioning member 2 is connected to the fixing member 1, and the other side of the fixing member 1 is adsorbed with the first door body 31. There is a gap between the first connection part 22 and the first door body 31 for setting the fixing member 1. The first section 211 and the fourth section 214 include an extension part 216 arranged outside the gap. The gap formed between the extension part 216 of the first section 211 and the extension part 216 of the fourth section 214 and the first connection part 22 is used for setting the fixing member 1. The first section 211 and the fourth section 214 include a body 215 arranged inside the gap, which is used to define the gap between the first door body 31 and the fourth door body 34 and the gap between the third door body 33 and the fourth door body 34.

[0053] Alternatively, if Figure 4 and Figure 5As shown, the fixing member 1 includes a second connecting portion 11 and a suction cup portion 12, the second connecting portion 11 is connected to the first connecting portion 22 to connect the positioning member 2 to the fixing member 1; one side of the suction cup portion 12 is connected to the second connecting portion 11, and the other side is configured to be adsorbed on the first door body 31.

[0054] The second connecting portion 11 is connected to the first connecting portion 22, so that the fixing member 1 is connected to the positioning member 2. The first connecting portion 22 is arranged between the extension portion 216 of the first section 211 and the extension portion 216 of the fourth section 214. A space is defined between the extension portion 216 of the first section 211, the extension portion 216 of the fourth section 214, the first connecting portion 22 and the first door body 31. The suction cup portion 12 of the fixing member 1 is arranged in this space, and the side close to the first door body 31 is adsorbed on the first door body 31, and can be moved up, down, left and right relative to the first door body 31 to adjust the position of the fixing member 1 to adjust the position of the positioning device. The side close to the first connecting portion 22 is connected to the second connecting portion 11, so that the suction cup portion 12 cooperates with the second connecting portion 11 to fix the positioning device at a suitable position of the door body 3.

[0055] Alternatively, if Figure 4 and Figure 5 As shown, the suction cup portion 12 includes a circular ring structure 121 and an extension structure 122. The inner side of the circular ring structure 121 is connected to the second connecting portion 11; the extension structure 122 is connected to the outer side of the circular ring structure 121 and extends in a direction close to the first door body 31 until it is adsorbed on the first door body 31.

[0056] The setting of the suction cup part 12 can realize the adsorption of the fixing part 1 and the outer surface of the door body 3. When the suction cup part 12 fits with the door body 3, the suction cup part 12 is pressed toward the door body 3. The material of the fixing part 1 is rubber. During the pressing process, the suction cup part 12 is deformed to form an enclosed space between the door body 3. The air pressure inside the enclosed space is lower than the air pressure outside the enclosed space. The external air pressure applies a force to the suction cup part 12 close to the outer surface of the door body 3, so that the suction cup part 12 fits tightly with the outer surface of the door body 3, so that the fixing part 1 is fixed to the door body 3.

[0057] Optionally, the ratio of the ring width to the thickness of the ring structure 121 is in the range of 2-5.

[0058] When the ring width of the circular ring structure 121 is small and the thickness is large, that is, the ratio of the ring width to the thickness is less than 2, the deformation ability of the circular ring structure 121 is weak, and the enclosed space formed with the extension structure 122 is relatively small, so that the adsorption force between the suction cup part 12 and the door body 3 is weak, and the fixing effect of the fixing member 1 is poor. When the ring width of the circular ring structure 121 is large and the thickness is small, that is, the ratio of the ring width to the thickness is greater than 5, the supporting ability of the circular ring structure 121 is weak, it is easy to deform, and the closure of the enclosed space cannot be guaranteed. The suction cup part 12 and the door body 3 are easily separated, and the fixing effect of the fixing member 1 is poor. When the ratio of the ring width to the thickness of the circular ring structure 121 is in the range of 2-5, the deformation ability of the circular ring structure 121 is good, the supporting ability is good, and it can ensure the closure of the enclosed space, realize the adsorption between the suction cup part 12 and the door body 3, and realize the fixing effect of the fixing member 1.

[0059] Alternatively, if Figure 5 As shown, the first connection portion 22 is provided with a through hole 221 , and the second connection portion 11 is passed through the through hole 221 and protrudes from the outer wall of the first connection portion 22 to form a boss structure 111 to fix the positioning member 2 .

[0060] The first connection part 22 cooperates with the through hole 221 to realize the connection between the fixing member 1 and the positioning member 2. The setting of the boss structure 111 enables the second connection part 11 to be fixed after passing through the through hole 221. The boss structure 111 protrudes from the outer wall of the first connection part 22 to prevent the second connection part 11 from falling off the through hole 221 of the first connection part 22, thereby enhancing the connection and fixation between the fixing member 1 and the positioning member 2.

[0061] Optionally, the outer diameter of the boss structure 111 is larger than the diameter of the through hole 221 , and the inner diameter is smaller than the diameter of the through hole 221 .

[0062] The fixing structure between the second connecting part 11 and the first connecting part 22 is a boss structure 111. When the inner diameter of the boss structure 111 is smaller than the diameter of the through hole 221, when the second connecting part 11 is penetrated in the through hole 221, the front end of the boss structure 111 can smoothly pass through the through hole 221. The second connecting part 11 is made of rubber. When the second connecting part 11 is penetrated through the through hole 221, the rear end of the boss structure 111, that is, the outer diameter, is an interference fit with the through hole 221. In the process of penetrating the through hole 221, the boss structure 111 is deformed and passes through the through hole 221. Since the outer diameter of the boss structure 111 is larger than the diameter of the through hole 221, the boss mechanism protrudes from the outer wall of the first connecting part 22, thereby playing the role of fixing the positioning member 2.

[0063] Optionally, the included angle of the boss structure 111 ranges from 16° to 36°.

[0064] like Figure 4As shown, the angle of the boss structure 111 is a. When the angle of the boss structure 111 is small, that is, the angle is less than 16°, the inclination angles of the front and rear ends of the boss structure 111 are small, and the difference between the outer diameter and the inner diameter of the boss structure 111 is small, so that the boss structure 111 can easily be separated from the first connecting part 22 through the through hole 221, resulting in the separation of the fixing member 1 and the positioning member 2, and the fixing effect is not good. When the angle of the boss structure 111 is large, that is, the angle is greater than 36°, the inclination angles of the front and rear ends of the boss structure 111 are large, and the difference between the outer diameter and the inner diameter of the boss structure 111 is large. It is difficult for the rear end of the boss structure 111 to pass through the through hole 221, and it is difficult to install. When the angle range of the boss structure 111 is 16°-36°, on the one hand, it can prevent the second connection part 11 from being separated from the first connection part 22, thereby achieving a better fixing effect between the fixing member 1 and the positioning member 2, and on the other hand, it makes the connection and installation between the second connection part 11 and the first connection part 22 smoother.

[0065] Alternatively, if Figure 4 As shown, the depth of the positioning member 2 extending into the gap between the plurality of door bodies 3 is L1, the thickness of the door body 3 is L2, and 0.4≤L1 / L2≤0.6.

[0066] When the depth L1 of the positioning member 2 extending into the gap between multiple door bodies 3 is small, that is, L1 / L2 is small, that is, L1 / L2 is less than 0.4, the depth of the positioning member 2 accounts for a small proportion of the thickness of the door body 3, and the determination of the gap distance and the gap position between the door bodies 3 is not accurate enough, and the subsequent installation effect of the door body 3 is not good enough. When the depth L1 of the positioning member 2 extending into the gap between multiple door bodies 3 is large, that is, L1 / L2 is large, that is, L1 / L2 is greater than 0.6, the depth of the positioning member 2 accounts for a large proportion of the thickness of the door body 3. After determining the gap distance and the gap position, the door body 3 is installed. If the depth of the positioning member 2 is too large, it may result in the inability to open the door body 3 when the positioning device is present, and the installation of the door body 3 cannot be checked before the positioning device is removed.

[0067] When 0.4≤L1 / L2≤0.6, the ratio of the depth of the positioning member 2 extending into the gap between the multiple door bodies 3 to the thickness of the door body 3 is moderate. On the one hand, the gap distance and gap position between the multiple door bodies 3 can be more accurately defined. On the other hand, the door body 3 can be directly opened and closed after the installation of the door body 3 is completed. Checking the installation condition of the door body 3 can prevent the positioning device from affecting the opening and closing of the door body 3. After confirming that the installation of the door body 3 is completed, separate the suction cup part 12 from the outer surface of the door body 3 and remove the positioning device.

[0068] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless explicitly required, individual components and functions are optional, and the order of operations may vary.

The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
