The present disclosure discloses a snake bone. The snake bone includes a plurality of structural units 100, each of the structural units 100 includes a first connecting pipe and a second connecting pipe. One end of the first connecting pipe is provided with a slot and a T-shaped structure, a clamping block and a limiting slot are provided on one end of the second connecting pipe, a limiting structure A is provided on both sides of one end of the limiting slot, and the other end of the limiting slot is provided with a limiting structure B; the clamping block and the T-shaped structure are located in the limiting slot, two flanks are provided on the original pin to form a T-shaped structure 6, and the T-shaped structure makes it difficult to disengage the pin, thereby increasing the strength of the snake bone in the direction perpendicular to the bend.

A non-metallic clip connection system includes a non-metallic clip having a substantially rectangular base portion, a first longitudinal flared wing portion, and a second longitudinal flared wing portion, wherein a plurality of edges of the clip along a path of insertion are beveled or radiused. The non-metallic clip connection system also includes a first non-metallic member having a first portion of a non-metallic clip receiver and a second non-metallic member having a second portion of the non-metallic clip receiver. The first non-metallic member is secured to the second non-metallic member by inserting the non-metallic clip in the non-metallic clip receiver. A non-metallic vertebrae bend restrictor and a non-metallic vertebrae end piece may use a non-metallic clip connection system.

A flexible support includes a first mounting channel for mounting a flexible water pipe, a second mounting channel for mounting a flexible supporting and positioning mechanism, a first connecting end, a second connecting end, and a support body. The support body capable of being bent and deformed. The support body coupled between the first connecting end and the second connecting end. The second mounting channel is located on one side of the first mounting channel. The first mounting channel and the second mounting channel respectively penetrate through the first connecting end, the support body and the second connecting end in sequence.

This invention is directed to a flexible device having a longitudinal axis, a first elongate member configured to move the flexible device in a first direction relative to the longitudinal axis, and a second elongate member configured to move the flexible device in a second direction relative to the longitudinal axis that is different to the first direction. The flexible device can also have an articulation section including a plurality of articulation links, wherein at least one of the plurality of articulation links can include a body configured to receive the first elongate member and the second elongate member. The flexible device can also include a cinching element configured to engage the first elongate member to substantially limit movement between the plurality of articulation links when a tensile force is applied to the first elongate member and configured to disengage the first elongate member to permit movement between the plurality of articulation links when a tensile force is applied to the second elongate member.

In order to provide a resin line that can be produced inexpensively, that meets the static requirements under action of the vacuum, and that enables a more precise discharge of the matrix material independent of the bending radii at which the resin line is laid, the resin line is formed of a corrugated pipe (2) whose wall comprises through openings (4). The through openings vary in regard to shape, size and/or frequency across a length of a corrugated pipe section of the corrugated pipe.

A refrigerated case includes a case body including a top panel, a rear panel, and a bottom that cooperate to define a display space, a portion of a refrigeration system disposed in the case and operable to cool a flow of air, and a first air passage positioned to direct the flow of air near the top panel from the rear panel generally toward a front of the case. A one piece holder is positioned to receive the flow of air adjacent the front of the case, the one piece holder formed as a unitary component using a PVC foam material and arranged to accelerate and redirect the flow of air in a downward direction toward the bottom, and a filter member is at least partially supported by the holder and positioned to receive the flow of air in the downward direction and to redirect that flow into the display space.
