Hole；And checkered steel plate, it is rectangle, the quadrangle of the checkered steel plate corresponds to the first circular hole of corner fixed sleeve part and middle part is fixed
The third circular hole of external member opens up slotted hole respectively, and pin can be allowed to be each passed through checkered steel plate, corner fixed sleeve part and telescopic rod
It carries out assembled fixed.
Preferably, in above-mentioned technical proposal, the second circular hole is arranged symmetrically with the midpoint of telescopic rod.
Preferably, in above-mentioned technical proposal, the adjustable hole assembly cover board is by being reserved in the PVC casings and U at hole
Shaped steel ring carries out reserved opening construction.
Compared with prior art, the utility model has the advantages that：The adjustable hole assembly cover board can be real
It is existing assembled easy to operate, there is stronger applicability and can be revolving, has higher carrying compared to traditional wooden cover board
Ability and rigidity, preferably realize the capping protection of reserved opening in engineering, and are remained after can also effectively avoiding conventional cover plate from using
Remaining material is difficult to utilize caused waste of material again.

Specific implementation mode
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
Novel protection domain is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figure 1, according to the concrete structure packet of the adjustable hole assembly cover board of specific embodiment of the present invention
It includes：Corner fixed sleeve part 1, telescopic rod 2, middle part fixed sleeve part 3, middle part telescopic rod 4, checkered steel plate 5 and pin 6.
Specifically, as shown in Figures 2 to 5, corner fixed sleeve part 1 is four, and each corner fixed sleeve part 1 is right angle
Shape, both ends all have the first telescopic rod socket, and upper surface both ends offer the first circular hole.
The outer diameter of telescopic rod 2 is slightly less than the internal diameter of corner fixed sleeve part 1 so that it is solid that telescopic rod 2 can freely pass into corner
To determine in external member 1, telescopic rod 2 is provided with multiple second circular holes 7 according to live reserved opening size, above by certain modulus, the
Two circular holes 7 are arranged symmetrically with the midpoint of telescopic rod 2, and 7 spacing of the second circular hole of both sides is divided into d1 and d2, and the difference of d1 and d2 are can
Flexible minimum length determines that both sides pin 6 penetrates the position of the second circular hole 7 according to the hole length of side.
One end of middle part fixed sleeve part 3 all has middle part telescopic rod socket, and the other end has the second telescopic rod socket.Middle part
The upper surface of fixed sleeve part 3 carries third circular hole.
The upper surface of middle part telescopic rod 4 is arranged the 4th circular hole of same form by telescopic rod 2.
