Afoot target, the weight that can also mitigate LCD TV accordingly without screwization of casing, to reach light-weighted purpose.
There is an urgent need for a kind of locks that can be realized lightweight and be connect with module group assembling without screw, by LCD TV rear shell for the prior art
Button.
Invention content
The purpose of this utility model is to provide a kind of connection locks of no screwization assembling, provide a kind of LCD TV
Rear shell and module are latched without the connection that screwization assemble, solve the problems, such as lightweight and appearance without screw, and casing
Assemble more accurate, security reliability higher.
To realize above-mentioned technical purpose and the technique effect, the utility model discloses a kind of no screwizations to assemble
Connection lock, include pin thread fastener and female thread fastener, pin thread fastener include pin thread supporting rack, pin thread catching groove and
Bullet, pin thread supporting rack are vertically to establish platy structure, and several pin thread supporting racks is mutually closed the bullet to be formed and be projected upwards,
Pin thread catching groove is offered on bullet and original pin thread supporting rack connected position, female thread fastener includes female thread pedestal, female thread
Supporting rack, release portion and rotational positioning component have vertically established two groups of female thread supporting racks, female thread supporting rack upper end on female thread pedestal
Portion turns down the button bit for being formed and being matched for the pin thread catching groove with pin thread fastener outward, and release portion is arranged in female thread supporting rack
Outside, rotational positioning component are mounted on the back side of female thread pedestal.
Preferably, further include having reinforcing rib, reinforcing rib is arranged in female thread supporting rack medial surface and female thread pedestal connection.
Wherein, rotational positioning component includes positioning column and rectangular spill spin block, and positioning column one end axis is connected in female thread pedestal
The back side, the other end are connected with rectangular spill spin block.
Preferably, further include thering are two groups of locating pieces, locating piece to be installed on the back side of female thread pedestal, separate from the two of positioning column
Side.
The utility model has the advantages that：
1. the utility model fixes TV by Optimal Structure Designing in such a way that male and female buckle fastener is combined
Front housing and back cabinet solve the problems, such as lightweight and appearance without screw, and the assembly of casing is more accurate, safely may be used
By property higher.
2. by the buckle structure rationally designed, install convenient eliminates the step of mounting screw, because in LCD TV,
Mounting screw needs multiple processes that can just complete, and such mode only needs very simple two steps：First, installation；Second,
Rotation；The installation that buckle can be completed, largely saves cost in this way, reduces the working hour of production, it is contemplated that in this road
In process, it is contemplated that the cost for reducing about 50% reduces for about 80% production process time.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As shown in Figs. 1-5, include pin thread buckle the utility model discloses a kind of connection lock of no screwization assembling
Part and female thread fastener, pin thread fastener include pin thread supporting rack 1, pin thread catching groove 2 and bullet 3, and pin thread supporting rack 1 is vertical
Platy structure is established, several pin thread supporting racks 1 is mutually closed the bullet 3 to be formed and be projected upwards, bullet 3 and original pin thread branch
Pin thread catching groove 2 is offered on 1 connected position of support, female thread fastener includes female thread pedestal 4, female thread supporting rack 5, release portion 6
With rotational positioning component, two groups of female thread supporting racks 5 have vertically been established on female thread pedestal 4,5 upper end of female thread supporting rack turns down outward
The button bit 10 to match for the pin thread catching groove 2 with pin thread fastener is formed, release portion 6 is arranged in the outside of female thread supporting rack 5,
Rotational positioning component is mounted on the back side of female thread pedestal 4, and rotational positioning component includes positioning column 7 and rectangular spill spin block 8, positioning
7 one end axis of column is connected in the back side of female thread pedestal 4, and the other end is connected with rectangular spill spin block 8.Reinforcing rib 9 is arranged in female thread supporting rack 5
Medial surface and 4 connection of female thread pedestal, locating piece 11 are installed on the back side of female thread pedestal 4, separate from the both sides of positioning column 7
Side.
The utility model without screwization assembling connection lock can application field be shell of liquid crystal display television fit on, tool
Body application process is as follows：
Step 1：In shell surface and two sides are dispersedly provided with pin thread fastener after television cabin；
Step 2：Open up mounting groove in the pin thread fastener corresponding position of television cabin front housing and rear shell, installation slot structure with
Rotational positioning element shapes are corresponding；
Step 3：Female thread fastener is installed in the mounting groove that front housing has opened up, the forward and backward shell of television cabin is corresponded to
Fastener gland closes real i.e. completion assembly.
Wherein, mounting groove includes square groove 12 and circular locating slot 13, and circular locating slot 13 is opened in square groove 12
Intermediate position.In order to coordinate the design of mounting groove, female thread pedestal 4 to use disc-shaped design, this kind design that can provide similar bullet
The elasticity of spring, after allowing product to be packed into more securely；The square groove 12 that female thread pedestal 4 completely covers mounting groove can be allowed to prevent liquid again
Brilliant module light leakage.
In the state that the assembly of female thread pedestal 4 is completed, the release portion 6 of 5 both sides of female thread supporting rack is pressed by being pinched with finger, then
Female thread pedestal 4 can be taken out by reversely rotating 90 degree.
It is verified by test, after pin thread is fastened with female thread, single pull-out force can reach 30N, with panel TV set
For 11, shell buckle is installed simultaneously, the pull-out force of assembly is not only 11 30N additions, and the performance of pull-out force can be
On the basis of original 330N, 50% pull-out force can be promoted, so big pull-out force is considerably beyond standard requirement.
