The utility model belongs to furniture connecting equipment technical field provides a kind of connecting structure for children room non-standard plate, including first connecting piece and second connecting piece. First connecting piece has hollow accommodating cavity, one end is provided with the jack hole being communicated with accommodating cavity, and accommodating cavity includes first accommodating section, and the radial dimension of first accommodating section gradually increases along the direction away from the one end of first connecting piece. Second connecting piece includes base portion and multiple elastic locking portions along the circumferential distribution of base portion, multiple locking portions can be gathered or expanded outward along the radial direction, and multiple locking portions can be moved into first accommodating section through jack hole. When locking portion is located in first accommodating section, locking portion keeps abutment with the inner wall of first accommodating section under the action of its own elasticity, to limit locking portion from first accommodating section. The connecting structure provided by the utility model has the advantages of strong adaptability, high safety, easy installation and neat appearance.

This invention discloses a standard plate for detecting the release of pollutants from building materials, its preparation, and its application. The standard plate includes a sealing outer jacket, a wooden board assembly, a sealing top cover, and a sealing plug. The bottom surface of the sealing outer jacket is perforated. The wooden board assembly, consisting of a bottom plate, a core plate, and a top plate, is nested within the sealing outer jacket and secured by the sealing top cover. The core plate contains porous material and has radial channels. The top plate and the sealing top cover have through holes at their centers, into which the sealing plug is inserted for sealing. In use, the target pollutant is dripped into the through holes. Centrifugation and vibration cause the target pollutant to diffuse through the channels and disperse into the porous material and other interstitial components within the core plate, resulting in a standard plate that can uniformly and stably release the target pollutant. By changing the type and concentration of the added target pollutant, the release of pollutants from different product control materials can be detected.

A manufacturing method of a compression-molded container bottom plate comprises the following steps: (1) laying a compression-molded base plate; (2) plate blank paving is conducted, specifically, paving raw materials are sequentially paved on a mould pressing base plate according to the requirements for the thickness and the breadth of the middle of a mould pressing forming container bottom plate; and (3) feeding the paved plate blank and the mould pressing base plate into a hot press together, and carrying out hot press molding. (4) longitudinal and transverse edge sawing is conducted, specifically, the hot-pressed rough board is cut into a specification board, and the compression molding container bottom board with the neat periphery is formed; and (5) returning the mould pressing base plate. The edge local density is larger than that of a non-edge part, the strength is higher, and the loading capacity is superior to that of a bottom plate of the same specification manufactured by milling a groove in the edge of a single bottom plate; the manufacturing cost is lower; the method can be widely used for manufacturing containers of various specifications.

The invention relates to the technical field of building construction, in particular to a post-cast strip water stop system of a basement outer wall and a post-cast strip water stop construction method of the basement outer wall. The post-cast strip water stop system of the basement outer wall is installed on one side of the basement outer wall and comprises a foundation plate, a standard plate and a water stop screw. The base plate comprises a first main body part and a mounting part. A first mounting block is convexly arranged at the top end of the mounting part; a first limiting groove is formed in the middle of the mounting part; each standard plate comprises a second main body part, a first connecting part and a second connecting part, and the first connecting part and the second connecting part are arranged above and below the second main body part respectively. And the water stop screw is vertically connected to the foundation plate and the standard plate, so that the side pressure of concrete is resisted, and meanwhile, water leaked accidentally can be drained. When the standard plate and the foundation plate are connected, the first limiting groove is connected with the limiting block in a clamped mode, the mounting groove is connected with the first mounting block in a clamped mode, and stable connection of the standard plate and the foundation plate is achieved through double fixation.

The utility model provides a non-standard plate grooving device, which relates to the technical field of non-standard part grooving, and comprises a grooving box, a position adjusting device is arranged on the outer side of the grooving box, the end part of the position adjusting device is connected with a two-dimensional moving mechanism, the two-dimensional moving mechanism is connected with a grooving mechanism, a fixing mechanism is arranged opposite to the grooving mechanism, and the grooving mechanism is connected with a positioning mechanism. The fixing mechanism is arranged on the inner wall of the grooving box, a discharging groove is formed in the bottom face of the grooving box, a safety door is hinged to the side face of the grooving box, and supporting plates are fixedly connected to the two sides of the bottom of the grooving box. The technical problems that in the prior art, due to the fact that grooving is not accurate or efficiency is low due to the fact that the existing grooving machine is prone to being influenced by skills and experience of operators, and the operators are likely to be injured accidentally due to the fact that some metal chippings splash in the grooving process are solved.

The invention discloses a programmed cooling instrument which comprises a heat preservation cabinet body, a first refrigerator, an air supply device and a control unit, the heat preservation cabinet body comprises a containing cavity capable of keeping the internal temperature, and a porous plate at the bottom allows air circulation and bears multiple sets of basket assemblies at the same time; the air supply device conveys a cooling medium generated by the first refrigerator into the whole containing cavity and is used for cooling the whole basket assembly. A cooling medium is communicated with the circulating air duct through the through hole array of the bottom perforated plate and the through hole array of the top perforated plate, so that airflow circulation is realized; the flow guide device guides the cooling medium to ensure that the cooling medium is uniformly distributed in the accommodating chamber and is accurately guided to the sample. According to the programmed cooling instrument, the cooling medium is conveyed upwards from the lower portion of the heat preservation cabinet body, the cooling medium is guided to the standard plate frames and the samples through the flow guiding device, the uniform cooling effect can be provided for the whole basket assembly, and the samples are prevented from moving among the different plate frames.
