The utility model relates to the technical field of junction boxes, in particular to a buckle type junction box convenient to disassemble and assemble, which comprises a box body, a box cover and a locking assembly, the box body is rotatably connected with the box cover, two ends of the box body are respectively provided with a wire inlet and a wire outlet, the locking assembly consists of a fixed part and a movable part, and the fixed part arranged in parallel left and right is connected with the box body. And movable pieces arranged in parallel left and right are connected to the box cover. According to the utility model, when the box cover is in contact with the box body, the first L-shaped plate and the clamping block are in contact with the matching groove formed in the matching block, and the second L-shaped plate and the self-locking block are inserted into the limiting grooves formed in a large number of fixing pieces, so that the first L-shaped plate and the second L-shaped plate form a double-self-locking structure; the problem that a common self-locking structure is loosened and falls off due to external force and leg contact is avoided, meanwhile, the fixing piece is connected to the mounting plate, and the fixing piece is rapidly replaced by disassembling and assembling the mounting plate so as to reduce later maintenance and use cost.

A biological sensor includes a sensor body configured to obtain biological information; a cover member having a housing space and an opening of the housing space, the sensor body being housed in the housing space; a first sheet member provided to face the opening in the cover member; and a second sheet member provided to face the cover member with the first sheet member being between the second sheet and the cover member. At least a part of an outer periphery of the first sheet member projects with respect to outer peripheries of the cover member and the second sheet member. Thereby, it is possible to provide a biological sensor that can be suppressed from being detached from a living body, and can suppress reduction in attachment sensation due to deformation of skin caused by a body movement of the living body.

The invention relates to the technical field of armored optical cable installation equipment, and discloses an armored optical cable clamping device and an optical cable clamping method.The armored optical cable clamping device comprises a device shell used for installing internal components, a clamping mechanism and a power block arranged on the side wall of the device shell in a sliding mode, and a first clamping plate is fixed to the outer wall of the power block; first sliding rods are symmetrically fixed to the inner walls of the upper side and the lower side in the device shell, sliding blocks are slidably arranged on the first sliding rods, and sliding plates, second moving plates, mounting plates, mounting rods, mounting plates and second clamping plates are arranged on the side walls of the sliding blocks through first supporting rods. The device is reasonable in design, the clamping mechanism can be driven to clamp and fix an armored optical cable without extra power, meanwhile, clamping and fixing of armored cables of different sizes can be better met, the applicability of the device is improved to a certain degree, and in addition, due to the arrangement of the locking mechanism, the clamping mechanism is convenient to use. Therefore, the clamping and fixing quality of the device on the armored optical cable is ensured.

The safe and reliable hand rail for the vertical open type display cabinet is provided with a hand rail body and an upper face plate, the hand rail body is provided with a bottom plate, a front fixing plate and a rear fixing plate are correspondingly fixed to the two sides of the lower face of the bottom plate, and a front vertical plate and a rear vertical plate are fixed to the upper face of the bottom plate in a spaced mode. The front vertical plate, the bottom plate and the rear vertical plate form a groove, and a guide pipe plate mounting part is connected with the rear vertical plate; the upper panel is formed by connecting a flat plate located at the upper end, a side plate located in the middle and a maintaining piece located at the lower end, an upper connecting pin containing part and a transverse plate are sequentially arranged on the inner face of the side plate from top to bottom, the flat plate is lapped on the front vertical plate, and the rear end face of the flat plate is also located on the front vertical plate. A first limiting plate and / or a second limiting plate are / is arranged at the front end of the bottom plate, the first limiting plate is horizontally located on the upper face or the lower face of the transverse plate, and the second limiting plate is vertically arranged in the upper connecting pin containing part.

The utility model discloses a stable geological surveying and mapping support, which relates to the technical field of geological surveying and mapping and comprises a telescopic rod, a supporting rod is connected with a hinged support I and a hinged support II, an inserting rod is movably connected with an inserting groove, and the inserting rod is connected with a spring and a guide rod; a lifting plate is heightened, a push rod is pushed leftwards to drive a movable rod, and the movable rod drives a second hinged support to enable a supporting rod to move upwards through a first hinged support; when the movable rod slides leftwards and the insertion rod slides on the movable rod, when the insertion groove is in contact with the insertion rod, the insertion rod is pushed into the insertion groove, the push rod is continuously pushed, the insertion groove and the insertion rod slide to compress the spring, and the spring passes through the insertion groove until adjustment is completed; during lowering, the rotating handle is rotated, the inserting rod is separated from the inserting groove, thrust applied to the push rod is slowly released, the lifting plate moves to a proper position to loosen the rotating handle, the inserting rod is inserted into the inserting groove to loosen the push rod, and adjustment is completed; the lifting plate can be heightened after the rotating handle is rotated to the lowest position; the problem that adjustment is inconvenient due to continuous rotation is solved, and the adjusting efficiency is improved.

The application discloses a low-height support device applied to cast-in-situ beam construction above a subway, which comprises two concrete bases constructed on both sides of the ground surface above the subway, and a lower sliding rail is arranged on each of the two concrete bases; an inclined support frame is connected to each of the lower sliding rails, and the upper ends of the inclined support frames on the two lower sliding rails are close to each other; the upper ends of each of the inclined support frames are connected to an upper sliding rail; the upper sliding rail is arranged above the two lower sliding rails and is parallel to the lower sliding rails, and the upper sliding rail and the lower sliding rails have the same guide direction; the upper and lower ends of each of the inclined support frames are respectively connected to a clutch mechanism; and the two clutch mechanisms are connected to the upper sliding rail and the lower sliding rail respectively. The low-height support device can avoid that the soil foundation above the subway bears external force, thereby ensuring the structural strength of the soil foundation above the subway and avoiding the soil foundation from floating or collapsing and the like. The low-height support device is suitable for the technical field of cast-in-situ beam construction above a subway in building construction.
