By a top fixing connection of pressure support between the tubular top of longitudinal supporting plate, described top pressure support includes a both ends open
The cylindrical support ring of structure, is provided with an annular groove at described support ring inwall, before described longitudinal supporting plate is embedded in
In the groove stated, described top pressure support also includes one and aforementioned cylindrical support ring annular stop connected vertically plate, described
The inner circle of annular stop plate is vertically installed with the top pressure ring of a tubular structure, the inner circle of described cross-brace plate and top pressure ring
Wall contacts connect.
As further innovation of the present utility model, by a cross section between described annular stop plate and cylindrical support ring
Connection ring for L-shaped platy structure connects, and connects the two ends, L-shaped right angle of ring respectively and between annular stop plate and cylindrical support ring
It is welded to connect.
As further innovation of the present utility model, described top pressure ring outer wall annular array is provided with some protruding thorn A,
The axis of protruding thorn A is coaxial with the longitudinal axis of top pressure ring.
As further innovation of the present utility model, on axial one end of the groove of support ring inwall, annular array is provided with
Some protruding thorn B, the axis of protruding thorn B and the axis coaxle of support ring.
As further innovation of the present utility model, the surface also annular array at described annular stop plate is provided with some
Play the protruding granule of rubbing action.
As further innovation of the present utility model, described cross-brace plate and longitudinal supporting plate are made of copper.
The beneficial effects of the utility model are:
1, this utility model is replaced traditional grand master pattern wall by a support frame structure thus is improved intensity, prevents chipping
Generation, and this bracing frame use inwall mosaic texture, inwall can the most individually be replaced after Reusability weares and teares
Effectively reduce cost.
2, connect ring and can improve bonding strength, reduce the probability of piece pendulum between annular stop plate and cylindrical support ring.
3, protruding thorn can realize cross-brace plate, the local deformation of longitudinal supporting plate and clamping, prevent because shake or
Person is impacted by a small margin and is got loose.
4, protruding granule can be nipped in cross-brace plate, it is ensured that fixed effect.
5, copper cross-brace plate and longitudinal supporting plate are prone to occlusion, it is not easy to get loose.
