The invention discloses a device for retreating grouting and a method for using it, which solves the problem in the prior art that the hole is prone to collapse and bury the grouting pipe, and solves the problem of hole wall collapse caused by plugging and expansion. , economical and practical, the beneficial effect of convenient operation, the specific scheme is as follows: a device for retreating grouting, including a casing, the diameter of the casing is smaller than the diameter of the borehole; the grouting pipe, the grouting pipe is arranged on the casing The inner side is movably connected with the casing so that the grouting pipe can move relative to the casing. The grouting pipe is provided with a grout outlet, and the sealing plug is sleeved in the circumferential direction of the grouting pipe, and the sealing plug is arranged close to the grouting outlet; The pipeline is arranged in the casing and on the side of the grouting pipe, and one end of the pipeline is connected with the sealing plug.

The invention discloses an extendable indoor balcony extension device, which comprises a wall top installation plate, an opening side plate is fixedly welded in the middle of the bottom of the wall top installation plate, and a force bearing is fixedly installed on the left side of the front side of the opening side plate. Supporting device, the back of the open side panel is provided with a balcony extension device, the extendable indoor balcony extension equipment adopts a fully open balcony protection device, on the one hand, it saves the drying space inside the balcony and increases the indoor area in disguise. At the same time, it replaces the traditional glass window, which increases the indoor light transmittance and ventilation and greatly reduces the indoor oppression. The main function of the drying rod is to dry the clothes at ordinary times. After the plate is closed, it can also play an anti-theft role. The main function of the fixed pulley and the limit pulley makes the wire rope pull up more smoothly, and the friction force can also play a role in derusting the steel wire rope.

The invention discloses extendible indoor balcony expansion equipment and a method. The extendible indoor balcony expansion equipment comprises a wall top mounting plate; the middle part of the bottomof the wall top mounting plate is fixedly welded with an opening side plate; a stress supporting device is fixedly mounted on the left side of the front side of the opening side plate; and a balconyextending device is arranged on the back side of the opening side plate. The extendible indoor balcony expansion equipment adopts a balcony protective device with all-opened design, so on one hand, the inner airing space of the balcony is saved and the indoor area is increased in disguise, and on the other hand, the traditional glass window is replaced, the indoor light transmittance and ventilation property are improved and the indoor repression sense is greatly reduced; an airing rod is mainly used for airing clothes at ordinary times, and a plurality of airing rods can play an anti-theft role after armorplate glass is closed; a fixed pulley and a limiting pulley are mainly used for enabling a steel wire rope to be lifted smoothly; and through a friction force, the effect of derusting the steel wire rope can be achieved.

The invention belongs to the technical field of photocurable additive manufacturing, and specifically discloses a bioceramic slurry used for high-performance DLP printing and a preparation method thereof. The bioceramic slurry comprises bioceramic powder, premixed solution, dispersant and release agent, wherein the mass ratio of the bioceramic powder to the premixed solution is 1: 7-7: 3, and thepremixed solution comprises polyethylene glycol and photocurable resin with a mass ratio of 3: 20-2: 5. The preparation method comprises the following steps of: uniformly mixing photocurable resin andpolyethylene glycol, adding dispersant into premixed solution for ultrasonic mixing uniformly, adding bioceramic powder into the mixed solution, and stirring uniformly, then adding release agent intothe bioceramic slurry initial body, and stirring uniformly, so as to prepare the bioceramic slurry. The bioceramic slurry prepared by the invention can facilitate the lifting of the green body and reduce the internal stress of resin curing in the forming process, reduce degreasing cracking, and improve the success rate in the printing and degreasing processes.

The invention relates to a high-strength anti-pinch garment which is characterized by comprising a garment body, a zipper and a pair of positioning strips.The zipper is mounted in the middle of the garment body, the pair of positioning strips is fixed onto the garment body and is positioned on two sides of the top of the zipper, and detaching zippers are arranged at sleeves of the garment body.The high-strength anti-pinch garment has the advantages that the high-strength anti-pinch garment with an inflation neck protector is provided with the pair of positioning strips, the weight of the high-strength anti-pinch garment can be increased, accordingly, the zipper can be smoothly zipped, and potential safety hazards of physical injury due to the fact that the neck of a wearer is easy to pinch when the wearer zips the zipper by the single hand can be reduced.

The invention provides a ceramic bowl achieving negative pressure fixing using principal of expansion caused by heat and contraction caused by cold of air, and relates to the field of ceramic bowls. The ceramic bowl comprises a bowl body and a tray, and the side of the bowl body is fixedly connected with a fixing block; through the arranged bowl body, first heat conductive metal, second heat conductive metal, third heat conductive metal, heat conductive holes, clamping grooves and an air bag, the heat of a cooked dish when the cooked dish is put into the bowl body can only be transmitted fromthe first heat conductive metal of the bottom of the bowl body to the second heat conductive metal to allow the second heat conductive metal to transmit heat to the third conductive metal, the heat istransmitted to the clamping grooves from the heat conductive holes by the third heat conductive metal, the ceramic bowl is firmly fixed, and the problem that most of existing ceramic bowls are hard to be hold horizontally due to the fact that too many dishes are loaded is solved.

The invention relates to clothing capable of preventing a zipper from pinching a body. The clothing comprises a clothing body (1), a zipper (2) and locating strips (3). The zipper (2) is arranged in the middle of the clothing body (1); a pair of locating strips (3) are fixed on the clothing body (1) and on the two sides of the top end of the zipper (2). The clothing with an inflation neck protector has the advantages that with the pair of locating strips, weight is increased, so that the zipper can be closed smoothly and the possibility is reduced that when a person closes the zipper with one hand, the zipper pinches the neck and injures the body.
