Abstract
Description
Technical Field
[0001] The embodiments of this specification belong to the field of boxes, and specifically relate to a box. Background Art
[0002] In some fields that require high anti-theft performance of boxes, such as logistics, warehousing, storage of personal belongings, or anti-theft electricity in the power industry, box safety has always been an important issue. In order to prevent theft, traditional boxes are mostly locked outside the box, such as mechanical locks or electronic locks, and the lock picking technology is constantly developing, so the cost of locks is also rising; especially when a large number of boxes need to be managed, because many locks are covered or disguised after being pried, it is difficult for managers to find them, so it is also difficult to recover lost items in time or interrupt the continued theft. In China, one way to prevent theft of electricity in the power industry is to add lead seals to the screws of the meter box. If the screws used to seal the box are unscrewed, the lead seal will be damaged. Even if the thief replaces the lead seal, it will be discovered because the lead seal has a unique number. However, using this method, the box can be opened by simply unscrewing the screws. The anti-theft ability of the box is very poor, and checking the lead seal number is time-consuming and labor-intensive, so from time to time there are fish that slip through the net and continue to steal electricity. Therefore, there is an urgent need for a box that can prevent being opened at a low cost and is easy to find after being opened. Utility Model Content
[0003] The embodiments of this specification provide a box that can prevent being opened at a low cost and cannot be restored after being opened, making it easy to be discovered.
[0004] The embodiment of this specification provides a box body, comprising: a shell, an insert; the shell is provided with an insertion port for inserting the insert into the shell;
[0005] The insert strip is provided with a first elastic outward expansion structure on its side, and the shell is provided with a first abutment structure on the insert strip insertion path to abut against the first elastic outward expansion structure to prevent the insert strip from retreating after being fully inserted into the shell;
[0006] The bottom of the insert is also provided with a second elastic outward expansion structure, and the shell is also provided with a second abutment structure that abuts against the second elastic outward expansion structure to prevent the insert from retreating after being fully inserted into the shell.
[0007] A supporting structure for supporting the bottom of the inserting strip is provided in the housing at the end of the inserting strip insertion path.
[0008] As a preferred solution, a limiting member is further provided in the housing on the insertion path of the inserting strip, which limits the degree of outward expansion of the first elastic outward expansion structure after the first elastic outward expansion structure abuts against the first abutting structure.
[0009] As a preferred solution, the limiting member has a limiting surface on a side close to the inserting strip, which can be completely fitted with the outer side surface of the first elastic outward expansion structure to limit the outward expansion degree of the first elastic outward expansion structure.
[0010] As a preferred embodiment, the support structure includes an elastic plate arranged in the shell and having an elastic direction perpendicular to the insertion direction of the insertion strip. The support structure also includes a snap-fit member arranged on a side of the elastic plate facing the insertion strip. The insertion strip is provided with a snap-fit hole that can be engaged with the snap-fit member.
[0011] As a preferred solution, a third abutment structure is provided in the housing upstream of the first abutment structure on the insertion path of the inserting rod, abutting against the first elastic outward expansion structure to prevent the inserting rod from retreating when it is not fully inserted into the housing.
[0012] As a preferred solution, the first elastic outward expansion structure is an elastic outward expansion strip; and the third abutment structure is a slot.
[0013] As a preferred solution, the shell is provided with at least one first operating hole which is blocked by the inserting strip after the inserting strip is fully inserted into the shell, and the inserting strip is provided with at least one second operating hole which can overlap with the first operating hole during the insertion of the inserting strip into the shell.
[0014] As a preferred solution, a serration is provided on the inserting strip, and an engaging portion is provided in the housing to engage with the serration to prevent the inserting strip from retreating after being fully inserted into the housing.
[0015] As a preferred solution, a stopper mounting hole is provided at one end of the insert that enters the housing.
[0016] As a preferred solution, the second abutment structure is an inner wall surface of the shell where the socket is provided.
[0017] The beneficial effects brought by the technical solutions provided by some embodiments of this specification include at least:
[0018] By providing the socket and the supporting component on the shell, it can be ensured that the insert strip is stably installed in the shell; and by providing the insert strip and the shell with a stopper component to prevent the insert strip from being pulled out, it can be well prevented from being pulled out after the insert strip is fully inserted; wherein, the first elastic outward expansion structure and the first abutting component abut each other from the side, and the second elastic outward expansion structure and the second abutting structure abut each other from the bottom, and the stopper structure respectively provided in two directions has a better stopper effect; therefore, in order to open the box, violent destruction must be carried out, and the box after violent destruction cannot be restored to its original state and is easily discovered; furthermore, the insert strip is inexpensive, which can save economic costs for users.

DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of this specification will be described clearly and completely below in conjunction with the drawings in the embodiments of this specification.
[0030] The terms "first", "second", "third", etc. in the description and claims of this specification and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.
[0031] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements described without departing from the scope of the present specification. Various processes or components may be appropriately omitted, substituted or added to each example. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, features described with respect to some examples may be combined in other examples.
[0032] See also Figure 1 , Figure 1 A schematic structural diagram of a box provided in an embodiment of this specification is shown.
[0033] like Figure 1-Figure 4 As shown, the system may at least include a housing 1 and an insert 2; the housing 1 is provided with a socket 3 for inserting the insert 2 into the housing 1;
[0034] The side of the insert 2 is provided with a first elastic outward expansion structure 4, and the housing 1 is provided with a first abutment structure 5 located on the insertion path of the insert 2 to abut against the first elastic outward expansion structure 4 to prevent the insert 2 from retreating after being fully inserted into the housing 1;
[0035] A second elastic outward expansion structure 6 is further provided at the bottom of the inserting strip 2 , and a second abutting structure 7 is further provided in the housing 1 to abut against the second elastic outward expansion structure 6 to prevent the inserting strip 2 from retreating after being fully inserted into the housing 1 .
[0036] A support structure 8 for supporting the bottom of the inserting strip 2 is provided in the housing 1 at the end of the inserting path of the inserting strip 2 .
[0037] It can be seen that by providing mutually abutting components in the insertion strip 2 and the shell 1, the insertion strip 2 can be effectively prevented from being pulled out after being fully inserted; the first elastic outward expansion structure 4 and the first abutment structure 5 abut against each other from the side, and the second elastic outward expansion structure 6 and the second abutment structure 7 abut against each other from the bottom, and the anti-retraction effect is better through the anti-retraction structures respectively provided in two directions.
[0038] It is understandable that at least one first elastic outward expansion structure 4 can be provided on the side of the insert 2, and at least one first abutment structure 5 can be correspondingly provided on the housing 1. Preferably, at least one group of first elastic outward expansion structures 4 can be symmetrically provided on both sides of the insert 2, and first abutment structures 5 can also be correspondingly provided on the housing 1 for abutment.
[0039] It can be understood that the second elastic outward expansion structure 6 is an outward expansion plate, and the second abutment structure 7 is an abutment surface. The plate-like structure can be designed to have a larger volume, such as widening and thickening the outward expansion plate, and increasing the contact area between the outward expansion plate and the second abutment structure 7, so as to better prevent the insertion strip 2 from being pulled out after being inserted into the shell 1.
[0040] It is understandable that, during the process of inserting the insert 2 into the housing 2, because the first pop-up outward expansion structure 4 and the second elastic outward expansion structure 6 have a certain volume, if the socket 3 is made too small, the insert 2 is easy to not be inserted, but if the socket 3 is made too large, the sealing effect is not good. Therefore, corresponding first elastic outward expansion structure 4 accommodating grooves and second elastic outward expansion structure 6 accommodating grooves can be made on the insert 2 for the first pop-up outward expansion structure 4 and the second elastic outward expansion structure 6, so that during the process of inserting the insert 2, the first pop-up outward expansion structure 4 and the second elastic outward expansion structure 6 can be retracted into the corresponding accommodating grooves and popped out again after passing through.
[0041] It can be seen that the socket 3 and the supporting member 8 provided on the housing 1 can support both ends of the insert 2 inserted into the housing 1 to prevent the insert 2 from falling or one end from drooping into the housing 1 .
[0042] It is understandable that an insertion track 17 can be provided at both ends of the shell 1 at the starting position of the insertion of the inserting strip 2, so that the insertion of the inserting strip 2 is more stable; in addition, a slot 11 can also be provided at a position avoiding the first abutment structure 5 and the second abutment structure 7 on the insertion path of the inserting strip 2, which can also make the insertion of the inserting strip 2 more stable.
[0043] See also Figure 2 , Figure 4 or Figure 6 As shown, in one embodiment of the present specification, a limiting member 9 is provided in the housing 1 on the insertion path of the insert strip 2 to limit the degree of expansion of the first elastic outward expansion structure 4 after the first elastic outward expansion structure 4 abuts against the first abutment structure 5 .
[0044] It is understandable that if only the first abutment structure 5 and the first elastic outward expansion structure 4 are used to abut on the retraction path of the insertion strip 2, when the insertion strip 2 retracts due to external force, the added limiting member 9 will play a certain protective role on the first elastic outward expansion structure 4 and prevent the first elastic outward expansion structure 4 from deformation, making the first elastic outward expansion structure 4 more solid.
[0045] See also Figure 2 , Figure 4 or Figure 6 As shown, in one embodiment of the present specification, the limiting member 9 has a limiting surface 901 on the side close to the insert 2 that can completely fit with the outer side of the first elastic outward expansion structure 4 to limit the outward expansion degree of the first elastic outward expansion structure 4 .
[0046] It is understandable that the stopper 9 can be a stopper support, which can also prevent the first elastic outward expansion structure 4 from deforming when the insert 2 is pulled out; however, if the stopper 9 is a stopper surface 901 that is completely in contact with the outer side of the first elastic outward expansion structure 4, when the insert 2 retracts under the action of an external force, a greater force is required to deform the first elastic outward expansion structure 4. Thus, by providing a stopper surface 901 that is completely in contact with the outer side of the first elastic outward expansion structure 4, a better effect of preventing the insert 2 from retracting can be achieved.
[0047] See also Figure 2 , Figure 3 or Figure 5 As shown, in one embodiment of the present specification, the support structure 8 includes an elastic plate 801 disposed in the shell 1 and having an elastic direction perpendicular to the insertion direction of the insertion strip 2. The support structure 8 also includes a snap-fit member 802 disposed on a side of the elastic plate 801 facing the insertion strip 2. The insertion strip 2 is provided with a snap-fit hole 10 that can be engaged with the snap-fit member 802.
[0048] It can be seen that, because the elastic plate 801 is provided with a snap-fitting member 802 on the side facing the inserting strip 2, when the inserting strip 2 is inserted into the housing 1, the inserting strip 2 is blocked by the snap-fitting member 802 on the elastic plate 801 in the insertion direction, and then the inserting strip 2 generates a force on the snap-fitting member 802, forcing the snap-fitting member 802 to move downward. Because the snap-fitting member 802 and the elastic plate 801 are connected, the elastic plate 801 also deforms downward perpendicular to the insertion direction of the inserting strip 2. When the inserting strip 2 is fully inserted, because the snap-fitting member 802 is engaged with the snap-fitting hole 10 on the inserting strip 2, the space is released and the deformation of the elastic plate 801 is restored. Because the snap-fitting member 802 and the snap-fitting hole 10 on the inserting strip 2 are engaged to form a stop-retraction structure, the inserting strip 2 fully inserted into the housing 1 can be better prevented from retreating.
[0049] It can be understood that the locking member 802 on the elastic plate 801 can be L-shaped or U-shaped.
[0050] It is understandable that the portion on the insert strip 2 that is engaged with the engaging member 802 may be an engaging groove or an engaging hole 10.
[0051] See also Figure 2As shown, in one embodiment of the present specification, a third abutment structure is provided upstream of the first abutment structure 5 on the insertion path of the insert 2 in the shell 1 to abut against the first elastic outward expansion structure 4 to prevent the insert 2 from retreating when it is not fully inserted into the shell 1.
[0052] It is understandable that, because the box involved in the utility model includes a shell 1 and an insert 2, that is, two parts are needed during use, there is a situation where construction workers lack parts or parts are lost during construction. In order to avoid this situation, the insert 2 can be partially inserted into the shell 1 before handing it over to the user, and a stop structure is provided in the box, that is, a third abutment structure is provided upstream of the first elastic outward expansion structure 4 on the insertion path of the insert 2 in the shell 1 to abut against the first elastic outward expansion structure 4 to prevent the partially inserted insert 2 from falling off from the shell 1, thereby preventing the loss of parts.
[0053] It can be understood that after the insertion strip 2 is fully inserted into the shell 1, if the insertion strip 2 is damaged by external force and is pulled out, the first elastic outward expansion structure 4 will be blocked by the first abutment structure 5. If the first abutment structure 5 fails to block, when the insertion strip 2 continues to be pulled out, the first elastic outward expansion structure 4 will be blocked by the third abutment structure again. The newly added third abutment structure can also better prevent the insertion strip 2 from being pulled out.
[0054] See also Figure 2 As shown, in one embodiment of the present specification, the first elastic outward expansion structure 4 is an elastic outward expansion strip; and the third abutment structure is a slot 11 .
[0055] It can be understood that the third abutment structure can be provided separately, or the existing components in the shell 1 can be fully utilized to abut against the first elastic outward expansion structure 4, so the third abutment structure can be a slot 11 provided in the shell 1 on the insertion path of the insert 2 and located upstream of the first elastic outward expansion structure 4 for stabilizing the insert 2. The first elastic outward expansion structure 4 is an elastic outward expansion strip. The first elastic outward expansion structure 4 shrinks in the slot 11 when the insert 2 is inserted, but after the first elastic outward expansion structure 4 passes through the slot 11, the first elastic outward expansion structure 4 fully expands, so when the insert 2 retreats, the first elastic outward expansion structure 4 retreats to the position of the slot 11 and cannot smoothly enter the slot 11, thereby blocking the retreat of the insert 2.
[0056] It can be understood that, if a plurality of first elastic outward-expanding structures 4 are provided on one side of the insertion strip 2, a plurality of first abutment structures 5 are provided at corresponding positions in the shell 1 to abut against the first elastic outward-expanding structures 4 to prevent the insertion strip 2 from retreating after being fully inserted into the shell 1; when the insertion strip 2 retreats, the first elastic outward-expanding structure 4 at the downstream will be blocked by the first abutment structure 5 at the upstream, thereby preventing the insertion strip 2 from retreating.
[0057] See also Figure 2 , Figure 3 or Figure 4 As shown, in one embodiment of the present specification, the shell 1 is provided with at least one first operating hole 12 which is blocked by the insertion strip 2 after the insertion strip 2 is fully inserted into the shell 1, and the insertion strip 2 is provided with at least one second operating hole 13 which can overlap with the first operating hole 12 during the insertion of the insertion strip 2 into the shell 1.
[0058] It is understandable that the insertion of the insert 2 into the shell 1 is mainly to seal the shell 1, to prevent the theft, replacement or addition of items in the box, and to prevent others from operating or tampering with the items in the box. The owner of the box must put items in the box or make initial settings in advance, so it is necessary to set corresponding operation holes on the box to facilitate the use of the box owner and allow the owner to close the operation holes after use. Therefore, a first operation hole 12 is provided on the shell 1, and a second operation hole 13 is provided on the insert 2 to overlap with the first operation hole 12 during the insertion of the insert 2 into the shell 1. The first operation hole 12 and the second operation hole 13 can be overlapped to facilitate the operation of the box; and the first operation hole 12 provided on the shell 1 is blocked by the insert 2 after the insert 2 is fully inserted into the shell 1, so that the box is closed.
[0059] It is understandable that there can be multiple operating holes. For example, in the power industry, multiple first operating holes 12 can be set on the meter box, each first operating hole 12 corresponds to a group of wiring terminals on the meter in the box, and multiple second operating holes 13 corresponding to the first operating holes 12 are also set on the plug 2. After all the operating holes are operated, the plug 2 is completely inserted into the shell 1 to close the shell 1.
[0060] In addition, multiple first operating holes 12 can be set on the shell 1, and only one second operating hole 13 can be set on the insert 2. The second operating hole 13 on the insert 2 can be matched with a first operating hole 12 on the shell 1 before operation, and then the insert 2 can be moved to make the second operating hole 13 on the insert 2 correspond to the next first operating hole 12 on the shell 1 and then operation can be performed, and so on, until all operations are completed, the insert 2 is inserted into the shell 1 to close the shell 1; in addition, a larger second operating hole 13 can be set on the insert 2 to include all the first operating holes 12 within the range of the second operating hole 13. After all operations are completed, the insert 2 is inserted into the shell 1 to close the shell 1.
[0061] It is understandable that the buckle hole 10 mentioned above may also be the second operating hole 13 on the inserting strip 2 , and the U-shaped buckle piece 802 and the second operating hole 13 cooperate to form a retreat-stopping structure.
[0062] See also Figure 2 , Figure 3 , Figure 4 or Figure 8 As shown, in one embodiment of the present specification, the inserting strip 2 is provided with a serration 14 , and the housing 1 is provided with an engagement portion 15 that engages with the serration 14 to prevent the inserting strip 2 from retreating after being fully inserted into the housing 1 .
[0063] It can be seen that a serration 14 is provided on the inserting strip 2, and a meshing portion 15 is provided on the shell 1. When the inserting strip 2 is inserted into the shell 1, the serration 14 on the inserting strip 2 and the meshing portion 15 on the shell 1 come into conflict. Since the inserting strip 2 has a certain elasticity, it will bend downward. After the serration 14 of the inserting strip 2 passes through the meshing portion 15, the serration 14 and the meshing portion 15 mesh with each other and release the space. The meshing serration 14 and the meshing portion 15 can prevent the inserting strip 2 from retreating after being inserted into the shell 1.
[0064] It is understandable that if Figure 4 As shown in FIG. 1 , a concave surface can be provided in the housing 1 on the insertion path of the inserting strip 2 from the insertion opening 3 to one end of the engaging portion 15 , so as to make it easier to insert the inserting strip 2 before reaching the engaging portion 15 .
[0065] See also Figure 2 or Figure 3 As shown, in one embodiment of the present specification, a stopper mounting hole 16 is provided at one end of the insert strip 2 that enters the housing 1 .
[0066] It is understandable that, as described above, by half-inserting the insert 2 into the housing 1 so that the two parts are given to the user as a whole, it is possible to prevent parts from being lost. However, the problem is that an accidental collision during transportation or a user's operating error may cause the insert 2 to be fully inserted into the housing 1 in advance, making the box unusable. In order to avoid this situation, a stopper mounting hole 16 can be set at one end of the insert 2 that enters the housing 1, and a bolt can be inserted into the stopper mounting hole 16 to prevent the insert 2 from being inserted into the housing 1 due to misoperation.
[0067] See also Figure 2 or Figure 7 As shown, in one embodiment of the present specification, the second abutment structure 7 is the inner wall surface of the shell 1 where the socket 3 is provided in the shell 1 .
[0068] It can be understood that the second elastic outward expansion structure 6 at the bottom of the insert 2 abuts against the second abutment structure 7 on the shell 1, which can prevent the insert 2 from being pulled out after being fully inserted into the shell 1. The second abutment structure 7 can be a separately set abutment block that abuts against the second elastic outward expansion structure, and the abutment block abuts against the second elastic outward expansion structure 6 with an abutment surface. Preferably, the second elastic outward expansion structure 6 can also directly abut against the inner side wall of the shell 1, because the inner side wall of the shell 1 is also an abutment surface, and the same abutment effect can be achieved, and there is no need to set the second abutment structure 7 separately, which is convenient for production and has lower costs.
[0069] The embodiments described above are merely preferred embodiments of this specification and are not intended to limit the scope of this specification. Without departing from the design spirit of this specification, various modifications and improvements made to the technical solutions of this specification by ordinary technicians in this field should fall within the scope of protection determined by the claims of this specification.
