The invention discloses a table with a segmentable telescopic table top, which comprises a table top with a fixed shape, two sets of table legs, a movable table bracket, two movable rails, and at least one movable table top that can be fitted on two beams. Owing to adopting the connection between the desktop and the movable table bracket through movable rails, the movable table bracket can be completely pulled out of the desktop while maintaining the connection with the desktop; The supporting legs of the tabletop are changed from four before stretching out to six after stretching. Therefore, the table of the present invention has the advantages that the tabletop can be stretched out in multiple sections, the support of the table legs is stable, and the size of the tabletop after stretching out can be doubled compared with the original tabletop. The advantages of the table make the table adaptable to the use demands of different numbers of people, and the number of people who can use the table after stretching out can be doubled or even more than the number of people who use the original table.

The invention relates to a slide. The slide comprises an upper-layer slide body, a lower-layer slide body and a pair of oppositely-arranged fixed guide rails, the two sides of the upper-layer slide body are slidably connected to the pair of fixed guide rails, the two sides of the lower-layer slide body are slidably connected to the pair of fixed guide rails, and the upper-layer slide body and thelower-layer slide body can slide independently. Therefore, a complex matching structure does not need to be designed, and the structure of the slide is simplified. When one of the upper-layer slide body and the lower-layer slide body and a corresponding sliding guide rail are damaged, the replacement is convenient, and the replacement cost is reduced. Moreover, the upper-layer slide body and the lower-layer slide body do not influence each other to slide, so that the movement stability of the upper-layer slide body and the lower-layer slide body is improved. Moreover, when the slide is stretched, the upper-layer slide body and the lower-layer slide body can move in opposite directions relative to the fixed guide rails, so that the upper-layer slide body and the lower-layer slide body are of a symmetrical structure relative to the fixed guide rails, the fixed guide rails are stressed in a relatively balanced manner, and the fixed guide rails can be protected.

The invention discloses a cementation and fracture technique string and a cementation and fracture technique process. The cementation and fracture technique string sequentially comprises a float shoe, a float collar, a collision base, a cementation pressure differential sliding sleeve and a cementation dropping sliding sleeve from bottom to top, wherein the float shoe, the float collar, the collision base, the cementation pressure differential sliding sleeve and the cementation dropping sliding sleeve are connected through a casing pipe, and the cementation pressure differential sliding sleeve is provided with a constant pressure valve. The cementation and fracture technique process comprises the steps of a well cementation process including tripping the cementation and fracture technique string into a wellhead, pouring cement paste into the cementation and fracture technique string, and waiting on cement setting after a rubber plug moves to the collision base, and a fracture process including pressurizing the cementation and fracture technique string from the ground to open the constant pressure valve arranged on the cementation pressured differential sliding sleeve and then performing fracture. The cementation and fracture technique string is low in rigidity, can be tripped into stratums very conveniently, and meanwhile can achieve good packing effects.

The invention discloses a food processor cover-closing safety protection device. In order to solve the problem of misoperation after cleaning, the existing food processor commonly adopts a rotary knob type and snap joint type protection structure, so that the personal safety under the condition of misopration is protected, but the protection structure is complex, and food cups cannot be taken and placed once the protection structure is failed. The food processor cover-closing safety protection device is characterized in that at least one lock catch is arranged on an outer edge of a cup cover; an arc-shaped groove for locating the lock catch is formed between an upper cover close to the cup cover and a top face of a main body; a safety stop lever capable of being moved up and down is arranged in the main body; a trigger rod capable of being moved up and down is arranged in a base, and is linked with the safety stop lever; an upper end of the trigger rod is a movable end contacted with a bottom part of the food cup; an elastic support piece is arranged between a lower part of the trigger rod and the base. The food processor cover-closing safety protection device cannot work if no food cup is placed on the base, so that the misoperation after cleaning is effectively prevented.

The invention discloses a locking mechanism for railway wagons, which includes a locking structure and a closing structure installed on sliding doors A and B. Both sliding doors A and B are equipped with interlocking latches, and the locking structure The sealing structure is connected with the sealing structure through the sealing transmission structure. The locking structure includes the active locking structure installed on the sliding door A and the passive locking structure installed on the sliding door B. The active locking structure drives the passive locking structure to realize the truck For the locking of the truck door, the locking structure moves while the sealing transmission structure in the sliding door A and the sliding door B is linked so that the sealing of the sliding door A, the sliding door B and the edge of the truck door hole is closed. The new structure proposed by the present invention is used to be installed on the carriages of railway freight cars, and the fastening of the lock is realized by designing a connected structure; at the same time, the stretchable rubber gasket is used to make the whole have a certain airtightness, and at the same time It will affect the sliding, so as to avoid the cross-wind from the door seam to the interior of the truck compartment.
