Description

Casing structure

The creation department is related to a set of column structure, in particular, a sleeve column structure is provided with a body and a lock, and the lock body can be rotated in the body, so that the sleeve column structure has anti-theft function.

As we have previously known, the conventional structure of the composite column is also the patent application filed by us, such as the Taiwan Patent Application No. 099205393, certificate number: M396058, patent name: sleeve elevator (hanging The anti-theft lock structure of the frame is characterized in that: the anti-theft lock structure of the sleeve elevator (cradle) comprises: a buckle body 10 comprising a set of joint segments 11 and a buckle The sleeve portion 17 has a guide groove 12 formed therein, and the inner edge of the guide groove 12 is formed with at least one limiting portion 32, and the connecting portion 11 corresponds to the limiting portion. The opposite position of the 32 is formed with at least one trimming area 14 , and the buckle section 17 is internally provided with a locking space 171 , the locking space 171 corresponding to the guiding groove 12 is through a rotating hole 15 and communicates with the A flap of the screw hole 15 passes through the groove 16, and a predetermined position of the outer edge of the buckle portion 17 is provided with a spring piece 18 and a buckle protrusion 19; a lock member 20 includes at least one guide body 21 and a rotor blade 25, wherein the rotor blade 25 is just inserted into the airfoil slot 16 of the buckle body 10 and is accommodated in the buckle lock 171, and the guide body 21 is received in the guide groove 12, and a rotation support shaft 26 is disposed between the guide body 21 and the rotor blade 25, and the rotation support shaft 26 is just ready for rotation a rotation branch positioned in the buckle body 10 The hole 15 is pivoted, and the outer edge of the guide body 21 is respectively formed into a finite plane 22, and the side edge of the rotor blade 25 is formed as a side rim 26; a cut-off member 30 is provided at one end. The cutting portion 31 is connected to the cutout portion 14 of the buckle body 10, and the inner edge of the cutting member 30 is formed with at least one limiting portion 32 corresponding to the buckle body 10; thereby, unless the cutting is broken The cut-off portion 31 of the cut-off member 30 cancels the abutting restriction of the rotor blade 25 on the elastic piece 18, so that the elastic piece 18 can be pressed, and the buckle convex portion 19 and the predetermined sleeve A are non-aligned lock. Buckle state, otherwise sleeve A cannot be removed and removed.

However, the absence of the structure of the patent is that, as shown in Figures 2 and 9 of the bulletin, the plurality of latching members 20 are assembled on a slide rail, and each of the latching members 20 is assembled. When a buckle body 10 is to be provided with an anti-theft structure, it is limited by the structural principle. Each of the buckle body 10 is provided with two cut-off members 30, so that each of the buckle body 10 is relatively complicated in structure. The buckle body 10 is provided with a cutting member 30, so that at least four moving sliders are required when the mold of the buckle body 10 is to be shot out of the buckle body 10, and the mold cost of the buckle body 10 is also high. When the mold of the same volume is provided with four moving sliders, only a small number of the buckle body 10 can be shot.

In view of the lack of the structure of the above-mentioned patent case, the creator has been engaged in the manufacturing experience of related industries for many years, and finally has a product that can solve the drawbacks of the composite column structure.

When the conventional sleeve structure has anti-theft function, each of the buckle body needs to have a cut piece, and each of the buckle grooves has a higher component cost, The creation department is related to a set of column structure, especially a sleeve column structure is provided with a body and a lock, the lock can be rotated in the body, so that the sleeve structure has anti-theft function, if the multiple fits If the column structure is set on a frame body, only two restriction bars are arranged on the frame body to limit the rotation of the lock member, and the second restriction bar can make the each column structure have anti-theft function, and thus cut costs.

The utility model relates to a sleeve column structure, wherein the sleeve column structure can be assembled with a hand tool piece having the same specification four-corner groove, which comprises: a system having a first sleeve portion, a first pocket, and a first a locking portion, a second receiving groove, a first pivot portion, a first abutting surface and a missing groove; a locking member is provided with a second fitting portion, and the second fitting portion is provided with a square groove of the same specification The second tool portion is fastened to the first sleeve portion, and the second portion of the second sleeve portion is provided with a second pivot portion for pivoting with the first pivot portion. a second clamping portion is disposed at one end of the second pivot portion, and a second abutting surface is disposed between the second pivot portion and the second locking portion, and the second clamping portion is forced to pass through the first receiving groove Wherein, the second abutting surface is engaged by the first abutting surface, so that the locking component is restricted from the second clamping portion and cannot be disengaged from the body, and the second clamping portion is provided with a limiting portion at one end thereof. The limiting end has a limiting surface at two ends, and the limiting surface is rotatable to align the first clamping portion or the misaligned first clamping portion.

If the plurality of sleeve structures are assembled on a frame, only two restriction strips are arranged on the frame to limit the rotation of the locking members, and the second limiting strips can make the each column structure have anti-theft function. . If the sleeve structure is implemented by the elevator structure, only the restriction member can be provided with the anti-theft function, and the sleeve structure can also have the anti-theft function if implemented in a single group.
