The utility model discloses an improved groove which is applied to the field of grooves and comprises a groove body, two soil retaining plates are arranged in the groove body, supporting frames are installed on the opposite sides of the two soil retaining plates, and two first transverse supporting plates and two second transverse supporting plates are further arranged in the groove body. The two soil retaining plates are arranged in the groove, the first transverse supporting plate and the second transverse supporting plate are supported through the two supporting frames respectively, the groove is used in cooperation with a concrete base, soil can be prevented from making direct contact with a pipeline during backfilling, the pipeline is prevented from being extruded by the pressure of the soil, and the pipeline is prevented from being corroded by moisture in the soil; the transverse supporting plate I and the transverse supporting plate II are supported between the two soil retaining plates, and when soil on the outer sides of the two soil retaining plates applies pressure to the two soil retaining plates, the transverse supporting plate I and the transverse supporting plate II can transversely support the two soil retaining plates to ensure that the two soil retaining plates cannot incline inwards.

The invention discloses sealing equipment and method for plastic packaging bag production, and relates to the technical field of plastic packaging bag production, the sealing equipment comprises a bottom plate, the top of the bottom plate is fixedly connected with a conveyor, the top of the conveyor is provided with a top plate, and supporting frames are fixedly connected between the four corners of the bottom of the top plate and the bottom plate; according to the sealing equipment and method for plastic packaging bag production, through the arrangement of the sealing mechanism, the surface of a plastic bag can be leveled through movement of a pressing block, wrinkles of the plastic bag are avoided, in addition, the plastic bag can be pressed and fixed through a pressing plate after being leveled, deviation of the plastic bag is avoided, and the sealing efficiency is improved. After pressing, the pressing block continues to move to drive the heat sealing device to move downwards to be tightly attached to the plastic packaging bag to seal the plastic packaging bag, operation is very convenient, the phenomena of wrinkles and deviation at the sealing position of the plastic bag can be avoided, and the sealing efficiency and the sealing effect of the plastic packaging bag are improved.

The utility model discloses a dental handpiece oil control rack which comprises bases and a dental handpiece body, the number of the bases is two, the side walls of the two bases are fixedly connected with an outer frame, two first clamping grooves are formed in the inner side of the outer frame in a spaced mode, and a first partition plate and a second partition plate are connected into the two first clamping grooves in a sliding mode respectively. A plurality of silica gel inserting holes are formed in the middle of the first partition plate and the middle of the second partition plate at intervals, a second clamping groove is formed in the inner side of the outer frame, and a tray is slidably connected into the second clamping groove. Through the structure, the oil control frame is convenient to clean, the dental handpiece cannot be damaged, the inclination phenomenon cannot occur when the dental handpiece is fully inserted, and the hand skin of an operator cannot be scratched by the hole.

The utility model relates to a kind of bored pile construction recyclable steel casing, belong to bored pile construction technical field.The bored pile construction recyclable steel casing, comprising: casing mechanism, casing mechanism includes casing body and support arc plate;Auxiliary mechanism, auxiliary mechanism includes upper limit arc plate, movable arc plate and lower limit arc plate;Two groups of upper limit arc plate are positioned to movable arc plate, when needing to disassemble steel casing, movable arc plate is rotated, movable arc plate is rotated with soil layer separation with small amplitude, and movable arc plate drives upper limit arc plate and lower limit arc plate small amplitude movement at this time, to drive upper limit arc plate and lower limit arc plate with soil layer separation, and then steel casing is segmented with soil layer separation, avoid relying on hoisting directly to steel casing whole body traction, leading to steel casing inner wall and soil layer friction is larger, to avoid steel casing deformation or cracking, to ensure the subsequent recycling of steel casing use.

This utility model discloses a rapid hoisting device for a porous boron carbide hot-pressing mold, relating to the technical field of hoisting devices. The proposed solution includes a hoisting platform with an integrally formed top connecting block. The top connecting block has symmetrically arranged limit openings on both sides. A horizontal bar is arranged on the top of the top connecting block, and a hook passes through the center of the top connecting block. A connecting rod is arranged in a ring around the periphery of the hoisting platform. By setting limit bolts, when the top of the mold body has connecting holes, a suitable number of limit bolts can be threadedly connected to the corresponding connecting holes and installed. The hoisting platform is then connected to the connecting rod via a connecting strap. When the mold body has extension ears, the two ends of a lifting strap passing through the center can be sleeved onto the outside of the extension ears as needed. Appropriate connection methods can be flexibly selected according to different situations, and multiple connection methods can be used when conditions permit, ensuring more stable and safe hoisting.
