Description

Shell for installing seal, shell assembly and electric energy meter

Technical Field

The utility model relates to a seal installation technical field, concretely relates to casing, casing subassembly and electric energy meter for seal installation.

Background

In order to prevent the housing from being opened illegally or to prevent illegal operation of a function button for programming, resetting, or the like provided on the housing, a seal member is often provided to be locked, the seal member including a seal line and a seal lock, and when the seal member is broken, it indicates that the housing is opened illegally or the function button is operated illegally.

However, when the seal member is mounted on the housing, the seal member protrudes from the surface of the housing, that is, the seal member is roughly suspended from the side wall of the housing or the upper surface of the housing, which has the following problems:

firstly, during packaging, the seal and the shell occupy larger space and larger volume as a whole;

secondly, in the using process, a user easily touches the seal lock to pull the seal line, and the seal line has the risk of being torn; or the seal lock is subject to forces and rattles during transport, and the seal lock easily wears the surface of the housing.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the first technical problem that will solve is to prior art's current situation, provides one kind when being used for installing the seal, and the less casing that is used for the seal installation of whole packing volume.

The utility model discloses the second technical problem that will solve is to prior art's current situation, provides a casing subassembly.

The utility model discloses the third technical problem that will solve is to prior art's current situation, provides an electric energy meter.

The utility model provides a technical scheme that above-mentioned first technical problem adopted does: a housing for mounting a seal, comprising

An upper housing;

the lower shell is used for being connected with the upper shell through a first seal piece, the first seal piece comprises a first seal line and a first seal lock, the first seal line respectively penetrates through the upper shell and the lower shell, and the first seal lock locks two ends of the first seal line;

the method is characterized in that:

the outer peripheral wall of the upper housing has an inwardly recessed depression for accommodating the first seal lock of the first seal member.

In order to guide the first seal lock to fall into the recess, the upper case also has a through hole communicating with the recess for the first seal line to pass through. After first seal line links to each other with first seal lock like this, the part of first seal line is located the perforation to guide first seal lock to fall into the depressed part.

In order to reduce the probability of upward movement of the first seal lock while shielding the first seal lock, the edge of the upper surface of the upper housing extends outward to form a shielding portion for shielding at least part of the first seal lock located in the recess portion in the up-down direction. So, the occlusion part shelters from first seal lock on the upper and lower direction, and from the upper surface of casing, first seal lock is at least local sheltered from and comparatively succinct, pleasing to the eye, and second the occlusion part has a spacing effect to first seal lock downwards, in casing transportation or use, and first seal lock is difficult to the rebound.

The upper case may have various structures, and preferably, the upper case includes

The main body is provided with a first upper opening which is opened upwards, and the main body is internally used for mounting a control module;

the cover body covers the first upper opening, and the lower part of the cover body is used for installing a communication module detachably connected with the control module;

Therefore, the method is tidy and unobtrusive. In addition, the shielding part extends out of the first upper opening, so that when the device needs to be detached, the hand of a user abuts against the shielding part and acts on the shielding part upwards, the communication module can be separated from the control module, the communication module is taken out, and the shielding part is used as a handle part.

In order to prevent the function key from being illegally operated, the upper shell is provided with a second upper opening which is opened upwards at a position adjacent to the depressed part, the second upper opening is provided with the function key which is used as a part of the upper shell, the function key is used for being locked with the other part of the upper shell through a second seal, and the depressed part is used for accommodating a second seal lock of the second seal.

The function keys are locked by the second seal so that the function keys, such as the programming key, the reset key, etc., are not illegally operated.

In order to facilitate observation of the condition of the indicator light, the cover body is provided with a transparent area for transmitting light of the indicator light on the communication module or the control module. Thus, the condition of the indicator light is convenient to be observed from the appearance of the shell through the transparent area.

In order to simulate the shape of the indicator light, the transparent region has a strip-shaped column extending up and down, which is aligned with the indicator light in the up-down direction. Through setting up the bar post, the light of pilot lamp corresponds the bar post for instruct to the user of being convenient for observes outside the casing.

In order to connect the upper shell and the lower shell, the sealing device further comprises a sealing screw for connecting the upper shell and the lower shell, the head of the sealing screw is positioned on the upper shell, the head of the sealing screw is used for a first sealing line of the first sealing piece to penetrate through, and the threaded part of the sealing screw is positioned on the lower shell. So, go up casing and lower casing and pass through the seal screw and link to each other, the casing is difficult to be opened illegally.

The utility model provides a technical scheme that above-mentioned second technical problem adopted does: a casing subassembly, includes foretell casing that is used for seal installation, its characterized in that: still include the first seal with upper housing and lower casing locking, thereby the tight wall that makes first seal lock and depressed part place of seal line offsets.

Therefore, a user is not easy to contact the first seal lock and pull the first seal line, and the first seal lock is not easy to shake and wear the surface of the shell.

The utility model provides a technical scheme that above-mentioned third technical problem adopted does: an electric energy meter, characterized by: including a housing for seal installation as described above.

Compared with the prior art, the utility model has the advantages of: the peripheral wall through last casing sets up inside sunken depressed part, is used for first seal lock to hold in the depressed part like this, and during the packing, holistic volume is less, is favorable to practicing thrift the packing space to protection seal.

In the modified scheme, through setting up the shielding part, the shielding part has the effect of three aspect, firstly be used for carrying on spacingly and making it be difficult to by the shift position to first seal lock position in upper and lower direction, prevent that first seal lock from being collided with, the surface of casing is also difficult to wearing and tearing to first seal line, secondly shelter from first seal lock, see from the upper surface, it is more succinct, the third is as application of force portion, when dismantling the lid, user's hand application of force upwards exerts force again in the shielding part, can separate lid and main part.
