The invention relates to a membrane filter cloth clamp for fixing a filter cloth, which includes the filter cloth clamp, a concave ring screwing surface in an inner ring surface of a filter cloth clamping ring is screwed on the screwing surface of the filter cloth clamp, an annular boss in the filter cloth clamping ring is matched with an annular concave platform in the filter cloth clamp, and a filter cloth inner clamp is clamped with the filter cloth clamp. The membrane filter cloth clamp has the advantages that firstly, the filter cloth clamp, the filter cloth clamping ring and the filter cloth inner clamp are matched and combined, then the membrane filter cloth clamp and the filter clamp form great friction coefficient and the fixed positioning which can be displaced, thereby avoidingthe shortcomings in the background technology and achieving the design purpose of the invention; secondly, facilitating the rapidly loading and unloading of the filter cloth .

The invention relates to a waterborne fluororesin nonstick coating, which is formed by 40 to 70 portions of modified polyte-trafluoroethylene (PTFE) water base resin, 10 to 30 portions of high temperature resistance pigment, 1 to 5 portions of fluororesin additive, 1 to 5 portions of surfactant and 20 to 40 portions of antiwear filler. The waterborne fluororesin nonstick coating uses synthesis propylene acid water base resin for modifying trafluoroethylene PTFE water base resin, adopts acrylic acid fat second polymerization method and does not use an addition agent, the entire fluorine caprylate compound which is harmful to human body in the modification process; the modified resin forms mosaic and perforating network structure, has good temperature dispersing region, solves the problem ofthe adhesiveness of the coating and the base material and the problems of baking and cracking, thus improving the hardness of nonstick coating. The NU aqueous fluorine resin of the invention does notstick to coating, can be coated on the surfaces of a microwave oven, an electric cooker, a nonstick pan and an electromagnetic pan, etc. to play the roles of protecting the surfaces from being stuckwith food, and causing food and aluminum and other metals to be isolated.

The invention discloses a bus handle with adjustable height. The bus handle comprises a fixing sleeve, a woven belt and a hand shank, wherein an upper end of the hand shank is provided with a telescoping system, one end of the telescoping system is provided with a locking mechanism, the woven belt passes through a woven belt hole at a lower end of the fixing sleeve, and another end of the woven belt is coiled in the telescoping system at the upper end of the hand shank; the fixing sleeve is composed of two clamping pieces, the upper end of the fixing sleeve is provided with a cross beam hole while the lower end thereof is provided with the woven belt hole; the telescoping system comprises a coiling block and a fixed shaft in the coiling block, the coiling block is connected with the wovenbelt, one end of the coiling block is provided with a tooth socket, one end of the fixed shaft is provided with a cross shaft type spline, the fixed shaft is provided with a tension spring, and one end of the tension spring is fixed on the fixed shaft while the other end thereof is fixed on the coiling block; and the locking mechanism comprises a chuck, jacking force spring, a camshaft piece and a push rod. Based on a machine design principle, the height of the bus handle can be adjusted so as to meet use requirements of different heights of people, and the bus handle is simple in structure and convenient to use.

The invention provides melting equipment and a melting method for growing a quartz crucible by thermal spraying. Firstly, a set of melting equipment for the quartz crucible and comprises a control main machine; the control main machine is directly connected with a feeding system and a plurality of thermal spraying molding devices at the lower positions are connected with a lateral side of the feeding system; the control main machine is further connected with an inductance heater and relative auxiliary equipment; a crucible melting method based on the equipment utilizes a thermal spraying growing method to melt the crucible; after a crucible mold is cooled, a baiting device keeps the baiting stability; melting parameters are controlled by the control main machine and three times of thermal spraying molding are carried out by utilizing baiting pipes of the thermal spraying devices to prepare a finished product crucible. The crucible prepared by the invention can be effectively adapted to some requirements of characteristics of long use time, high temperature and high required purity on the quartz.

The invention discloses a detector for detecting axial displacement degree of a coupling. A rotatable square shaft assembly (7) is arranged between two telescoping slide ejector block assemblies (1). The tops of the two telescoping slide ejector block assemblies are provided with two tension springs (10) so that the two telescoping slide ejector block assemblies are connected. The bottom face and the two side faces of the telescoping slide ejector block assemblies and the rotatable square shaft assembly are provided with housings (2, 13). The middle of the bottom housing is provided with a long elliptic opening groove (21). One side of the opening groove is in ellipse shape and is provided with a dial gauge inlay sleeve (9), wherein the inlay sleeve is fixedly arranged on one telescoping slide ejector block assembly and is internally provided with a dial gauge in a close-fitting manner. The other side of the opening groove extends out of an ejector rod stop block (5), wherein the ejector rod stop block is fixedly arranged on the other telescoping slide ejector block assembly. A dial gauge detection ejector rod (6) supports the ejector rod stop block. A spanner clamps a square-edged shaft body shaft core (17) on the rotatable square shaft assembly and thus the telescoping slide ejector block assemblies can be driven to move. The dial gauge is capable of measuring movement amount of the telescoping slide ejector block assemblies.

The invention relates to a wavy sealing check ring combined rotary dynamic sealing structure. The wavy sealing check ring combined rotary dynamic sealing structure is mainly composed of an abrasion-resisting and low-friction polymer check ring and a standard rubber O-shaped ring. In the working process of the sealing structure, the O-shaped sealing ring deforms under pressure of high-pressure liquid and is tightly attached along the wavy end face of the wavy check ring. In the high-speed rotation process of a pump shaft, the O-shaped sealing ring deforms in three directions and is tightly attached to the surfaces of a shell, the check ring and a rotary shaft, and it can be ensured that high-pressure liquid in another direction cannot leak out from a gap.

A transparent painting film comprises a transparent painting layer and backing paper, a white developing film is arranged between the transparent painting layer and the backing paper, and a plurality of through holes are distributed in the white developing film intensively. In the utility model, as the white developing film is arranged between the transparent painting layer and the backing paper, pictures painted on the transparent painting layer can be display very clearly through the white developing film, the contrast performance of the pictures on the transparent painting layer can be enhanced, and the interference caused by other scenes behind the pictures can be prevented, so that the pictures can be displayed clearly and the visual effect is good, furthermore, the plurality of through holes are distributed in the white developing film intensively, the perspective effect can be met under the condition of ensuring the clear picture display, so that people can clearly see the content of the picture from two sides of a transparent plate; in addition, the transparent painting film has the function of discharging air automatically, and prevents the phenomena of bubble generation and the like when in sticking, so that the construction difficulty is reduced. The transparent painting film also has the advantages of simple structure, convenient sticking, durability and the like, and can be used on glass, vehicle windows or other transparent plates.
