Abstract
The utility model proposes a kind of power storehouse loss of weight sealing structure, power storehouse weight can be significantly reduced under the premise of ensureing to be connected and fixed and waterproof sealing effect.The power storehouse loss of weight sealing structure includes warehouse, warehouse lid, annular sealing strip and several attachment screws, the rib portion of warehouse side wall only retains the angular region on top for installing attachment screw, and it is sky below the angular region on top, corresponding rib portion region forms the rounded corner of radius bigger to contract, the shape of the annular sealing strip is the rectangle (the rounded corner projection of shape of warehouse side wall is consistent with annular sealing strip) with the rounded corner, and the endless belt that warehouse side wall top and warehouse lid are equipped with the annular sealing strip is located at the inside of the angular region.
Description
Technical field
The utility model is related to a kind of power supply chamber structures, are particularly suitable for high-power LED lamp.
Background technology
The general of high-power LED lamp is made of radiator grille, light source board, radiating shell and power storehouse.Power storehouse it is basic
Shape is mostly cuboid, usually requires to carry out by screw fit sealing rubber ring between the ontology of power storehouse and the rear cover of power storehouse
It is connected and fixed (for example, screw is respectively set at four angles, four edges midpoint), and ensures waterproof sealing.
For example, Chinese patent ZL201521071799X (the nested type sealing structure of power storehouse on LED light radiating shell),
Sealing ring is set between warehouse and warehouse lid；The circle of top one of warehouse side wall is the straight solid form in smooth end, sealing ring lower potion
With groove, which is adapted with the top one of warehouse side wall circle so that sealing ring can be to one cast of warehouse top side wall
It is wrapped up at three bread；The circle of medial surface one of warehouse lid is provided with groove compatible with sealing ring shape so that can be to close when closing lid
Seal forms tight.In order to reserve the installation site of screw, four rib positions of power storehouse ontology need the structure
Widen inwardly, also therefore increases the weight of power storehouse, be unfavorable for the balance of LED lamp overall weight.Moreover, sealing ring exists
There are larger bending in four rib positions, also influence the service life of sealing ring.
Utility model content
The purpose of this utility model is to propose a kind of power storehouse loss of weight sealing structure, can be connected and fixed and prevent ensureing
Under the premise of water-stop effect, power storehouse weight is significantly reduced.
The solution of the utility model is as follows：
The power storehouse loss of weight sealing structure, including warehouse, warehouse lid, annular sealing strip and several attachment screws, warehouse side
The rib portion of wall only retains the angular region on top for installing attachment screw, and is sky below the angular region on top, corresponding rib portion region
The rounded corner of radius bigger is formed to contract, the shape of the annular sealing strip is the rectangle (warehouse with the rounded corner
The rounded corner projection of shape of side wall is consistent with annular sealing strip), warehouse side wall top is equipped with the ring packing with warehouse lid
The endless belt of item is located at the inside of the angular region.
Here " endless belt " is not to a certain entity, but finger ring shape sealing strip and its corresponding (warehouse side wall top
End and warehouse lid) region.
Based on above scheme, the utility model has also further made following important optimization：
Other than the rib portion top of warehouse side wall is provided with attachment screw, it is provided in the middle part of every one side on warehouse side wall top
Protruding portion at one horizontally outward, warehouse lid are correspondingly provided with matching protruding portion, are also used for installation attachment screw, thus into
One step improves sealing and installs fixed reliability.
The site portion hollow out that attachment screw is installed in warehouse lid, makes its thickness be less than the thickness of warehouse lid ontology.
The angular region thickness on top is 2cm-5cm.
The screw head of attachment screw is located at warehouse lid side, and the end of thread is located at warehouse side.
The annular groove placed for annular sealing strip is set to warehouse lid.
The annular sealing strip is filled in the annular groove, warehouse side wall top is provided with annular corresponding to annular groove
Protrusion so that when attachment screw tightening the annular protrusion contact and squeeze annular sealing strip annulus central area it is close to improve
Seal effect.
The utility model has the advantages that：
Sealing ring is made corresponding " reduction " without bending, four angular zones of power storehouse top side wall, only need to meet installation
The connection of screw, to achieve the purpose that loss of weight.
Similarly, also make Lightened structure design in power storehouse rear cover, further reduced the weight of power storehouse, make high-power
LED lamp overall weight is more balanced.

Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, power storehouse is mainly made of warehouse 1 and warehouse lid 2, and the rib portion 100 of warehouse side wall only retains top
The angular region 101 at end is sky below the angular region on top for installing attachment screw, and corresponding rib portion region forms half to contract
The shape of the rounded corner 1012 of diameter bigger, annular sealing strip 4 is the rectangle (rounded corner of warehouse side wall with consistent rounded corner
Projection of shape is consistent with annular sealing strip), the endless belt that warehouse side wall top is equipped with annular sealing strip with warehouse lid is located at angle
The inside in area 101.
The protruding portion 102 at one horizontally outward is additionally provided in the middle part of every one side on warehouse side wall top, warehouse lid is accordingly arranged
There is matching protruding portion 202, is also used for installation attachment screw 3.
The site portion hollow out that attachment screw 3 is installed in warehouse lid, makes its thickness be less than the thickness of warehouse lid ontology, further subtracts
Weight.The angular region thickness on warehouse side wall top is 2cm-5cm.
