Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

As shown in fig. 1 to 8, the joint block assembly 1 according to the embodiment of the present invention includes a fixing plate 10 and a plurality of joint blocks detachably stacked on a side surface of the fixing plate 10 in a thickness direction of the fixing plate 10, the joint blocks having a substantially rectangular shape.

As shown in fig. 1 and 2, the joint blocks are rectangular blocks, the joint block at the foremost side is attached to the fixing plate 10, and the other joint blocks are sequentially arranged backwards and stacked. It can be understood that a plurality of joint blocks and the fixing plate 10 are all provided with independent structural members, that is, the joint block assembly 1 is formed by combining a plurality of independent structural members, and the connection between the structural members can be disassembled.

As shown in fig. 8, the joint block has first and second

opposite end surfaces

60 and 70 in a length direction thereof, the joint block has top and bottom

opposite surfaces

90 and 80 in a width direction thereof, each of the joint blocks has a plurality of channels 50 therein, one end openings of the channels 50 are formed on the first or

second end surface

60 or 70, and the other end openings of the channels 50 are formed on the top or

bottom surface

90 or 80.

It should be noted that the joint block assembly 1 of the present application is commonly used for hose connection between a fixed structural member and a moving structural member of an apparatus, and referring to a rectangular joint block shown in fig. 2, a first end surface 60, a top surface 90 and a bottom surface 80 thereof are perpendicular surfaces, and a second end surface 70, a top surface 90 and a bottom surface 80 thereof are also perpendicular surfaces, so it can be understood that an opening at one end of the channel 50 is formed on the first end surface 60 or the second end surface 70, and an opening at the other end is formed on the top surface 90 or the bottom surface 80, and the opening at one end of the channel 50 can be oriented orthogonally to the opening at the other end of the channel 50, so as to complete 90 ° rotation of an external hose.

Further, the openings at one end of the plurality of channels 50 are arranged at intervals along the width direction of the joint block and are arranged in one or two rows in the thickness direction of the joint block, and the openings at the other end of the plurality of channels 50 are arranged at intervals along the length direction of the joint block and are arranged in one or two rows in the thickness direction of the joint block. It can be understood that, when the 50 openings of passageway are arranged in one row, the both sides of waiting to dismantle external rubber tube all can provide operating space for repair tools, and when the 50 openings of passageway were arranged in two rows, one side of waiting to dismantle external rubber tube can provide operating space for repair tools.

The inventor finds that the joint block in the related art comprises a plurality of rows of arranged passage ports, after the passage ports are connected with an external rubber pipe, if the rubber pipe positioned on the inner side relatively needs to be replaced, the joint block needs to detach the rubber pipe of the outer ring in order to provide an operation space for a dismounting tool, so that the problem of complex maintenance process exists, and the plurality of detached rubber pipes need to be marked, so that the phenomenon of mistaken connection is avoided when the joint block is reconnected, the workload is increased, and the working efficiency is low.

Based on the above problem, this application is through dividing into a plurality of joint blocks of dismantling the connection with joint block subassembly 1 to only arrange one or two passageway 50 openings on a side of joint block, then the external rubber tube in one side of every joint block forms two at most and arranges, when needs change or maintain arbitrary rubber tube, only need dismantle the joint block that the place got off, there is the space that can supply the maintenance tool operation in at least one side of the rubber tube of connection on the joint block, need not dismantle all the other rubber tubes.

In other words, the second joint block 30 may be directly connected to the first joint block 20 by a connector, or may be connected to the fixing plate 10 by a connector passing through the first joint block 20.

Therefore, in the concrete implementation, the connection mode can be reasonably selected according to the self weight of the joint block and the convenience of connection. For example, a connector block closer to the fixing plate 10 may be selected to be directly connected to the fixing plate 10, and a connector block farther from the fixing plate 10 may be selected to be connected to an adjacent connector block. The criterion for the distance is determined according to the specific situation, and is not limited herein.
