Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

Example 1

As shown in fig. 1 to 5, a preferred embodiment of the mounting structure of the lock nose of the box body is shown.

The mounting structure of the box lock nose comprises a base 1, a box cover 2 arranged on the base 1, and a lock nose 3 arranged between the base 1 and the box cover 2.

The lock nose 3 includes a lower half portion and an upper half portion connected to each other, the lower half portion is connected to the base 1, and the upper half portion extends out of the base 1 and is connected to the case cover 2. The lower half part of the lock nose 3 and the base 1 are separate pieces. In this embodiment, the lower half portion of the lock nose 3 is partially clamped with the base 1 by a buckle, and in other embodiments, the lower half portion of the lock nose 3 may be connected with the base 1 by gluing or the like. Preferably, the lock nose 3 is made of metal to increase strength.

Specifically, the base 1 has a first jack 11, the lower half portion of the lock nose 3 includes an insertion portion 31 inserted into the first jack 11, the insertion portion 31 is provided with a limiting hole 33, the limiting hole 33 can be replaced by a limiting groove, and the first jack 11 is provided with an elastic hook 12 connected with the limiting hole 33 in a clamping manner. The elastic hooks 12 are two and distributed on the left and right sides of the insertion part 31, and in other embodiments, the number of the elastic hooks 12 can be set according to the requirement, for example, 3 to 4. In order to reduce the wobbling of the locking nose 3, the lower half portion of the locking nose 3 further includes a limiting portion 34 extending from the insertion portion 31 toward the hole wall of the first insertion hole 11, and the limiting portion 34 is close to the hole wall of the first insertion hole 11. The hole wall of the first insertion hole 11 is provided with a positioning lug 13 for positioning the limiting part 32, on one hand, the positioning lug 13 limits the limiting part 34 to reduce the separation of the lock nose 3 from the elastic clamping hook 12 due to the position change caused by shaking, on the other hand, the positioning lug 13 also plays a role in positioning during installation, and when the lock nose 3 is inserted, the limiting part 32 of the lock nose 3 abuts against the positioning lug 13, namely, the lock nose 3 is installed in place.

The upper half part of the lock nose 3 is inserted and matched with the box cover 2. The cover 2 has a connecting portion having an insertion groove 21 for inserting the upper half portion of the locking lug 3, the insertion groove 21 is communicated with the first insertion hole 11, the cover 2 further has a second insertion hole 22 communicated with the insertion groove 21 in the left-right direction, the upper half portion of the locking lug 3 has a locking hole 35 communicated with the second insertion hole 22, and a locking member (not shown in the figure) passes through the second insertion hole 22 and the locking hole 35 to connect the upper half portion of the locking lug 3 with the cover 2, and the locking member may adopt the prior art.

In this embodiment, what adopt the mounting structure of box lock nose is the ammeter case for hold and protect the electric energy meter, prevent that the electric energy meter is illegal to be opened and is stolen electricity etc.. In other embodiments, the items within the case may be other items, such as other meters, money, watches, etc.

In the present embodiment, the use principle of the mounting structure of the box body lock nose is as follows.

During installation, the lower half part of the lock nose 3 is inserted into the first insertion hole 11 of the base 1, the insertion part 31 of the lock nose 3 abuts against the positioning lug 13, and at the moment, the elastic clamping hook 12 in the first insertion hole 11 is clamped into the limiting hole 33 of the lock nose 3, so that the connection between the lower half part of the lock nose 3 and the base 1 is completed.

Next, the inserting groove 21 of the lid 2 is aligned with the upper half of the locking lug 3, the locking hole 35 of the locking lug 3 is aligned with the second inserting hole 22 of the lid 2, and then the locking member passes through the second inserting hole 22 and the locking hole 35 to connect the upper half of the locking lug 3 with the lid 2.

Because the lower half of lock nose 3 and base 1 are components of a whole that can function independently, produce base 1 earlier, install lock nose 3 again, because base 1 does not have sheltering from of mould and operating space is bigger, install lock nose 3 to the position that base 1 corresponds comparatively accurately easily to the position that the upper half of lock nose 3 is connected with case lid 2 is difficult to have the deviation and can not influence the connection and the locking between lock nose 3 and case lid 2.

Directional terms such as "upper", "lower", "bottom", "left", "right", and the like are used in the description and claims of the present invention to describe various example structural parts and elements of the present invention, but are used herein for convenience of description only and are to be determined based on example orientations shown in the drawings. Because the disclosed embodiments of the present invention may be oriented in different directions, the directional terms are used for descriptive purposes and are not to be construed as limiting, e.g., "upper" and "lower" are not necessarily limited to directions opposite to or coincident with the direction of gravity.

Example 2

As shown in fig. 6 to 10, another preferred embodiment of the mounting structure of the lock nose of the case is shown.

The installation structure of the box body lock nose is basically the same as that of the box body lock nose of the embodiment 1, and the difference is that: the lower half of the locking nose 3 of this embodiment further includes a bent portion 32 connected to the insertion portion 31, the bent portion 32 and the insertion portion 31 form an angle, and the bent portion 32 and the base 1 are connected by a fastening member (not shown in the figure) in the prior art, for example, the fastening member may be a bolt or a rivet. The hole wall of the limiting hole 33 of the lock nose 3 is clamped with an elastic clamping hook 12.

The lower half part of the lock nose 3 is connected with the fastening piece through the elastic clamping hook 12, so that the position of the connection between the lock nose 3 and the base 1 is more, and the connection is more stable.
