According to the invention, the movable piece 12 is slightly moved upwards or downwards by screwing the movable piece 12, so that the adhesion degree between the movable lower part and the bottom of the cavity of the fixed piece 11 is adjusted, and the connection and disconnection between the air inlet channel 113 and the vacuumizing interface 114 are controlled, so that the inside of the charging bucket is vacuumized and the charging bucket is sealed.
When the upper cover 30 is locked, the lower rotating block 42 is rotated, so that the lower end of the lower rotating block 42 is inserted into the groove part, and the rotating block is rotated, so that the contact area between the inclined surface of the lower rotating block 42 and the inclined surface of the upper locking block 43 is increased, and the contact of the inclined surface and the inclined surface of the upper locking block 43 is tighter, thereby realizing locking. When the upper cover 30 is opened, the lower rotating block 42 is reversely rotated.
Compared with the conventional mode of locking by adopting a threaded screw, the mode is more convenient and faster to operate, and the problem that the thread tooth tip part is adhered and fused because of being fused at high temperature does not exist.
Further, the inclined surface of the upper rotating block 44 is a plane, and the inclined surface of the lower locking block 45 is a plane, so that the two surfaces are attached.
Referring to fig. 11 to 14, further, as another embodiment, the wedge-type connector 40 includes a connecting pin 41, an upper rotating block 44, and a lower locking block 45, wherein the connecting pin is inserted into a pin hole of the upper cover 30 and the flange, the upper rotating block 44 is fixedly disposed on a sidewall of the connecting pin 41, a lower surface of the upper rotating block 44 is an inclined surface, a lower end of the lower locking block 45 is fixedly connected with the upper cover 30, and an upper end surface is an inclined surface, so that a lower surface of the upper rotating block 44 is matched with an upper end surface of the lower locking block 45.

Further, the inclined plane of the lower surface of the upper rotating block 44 is an arc inclined plane, the inclined plane of the upper surface of the lower locking block 45 is an arc inclined plane, and the arc inclined plane is vertical to the side wall of the pin shaft everywhere, so that the arc inclined planes of the two are jointed everywhere in the process of relative rotation.
Further, the cavity of the fixed member 11 includes a cylindrical cavity and a conical cavity with equal diameters, the conical cavity is located at the bottom of the cavity, the cylindrical cavity is located above the conical cavity, the movable member 12 includes a cylindrical body and a conical body with equal diameters, the outer diameter of the cylindrical body of the movable member 12 is smaller than the inner diameter of the cylindrical cavity of the fixed member 11, so that the cylindrical body and the conical cavity of the movable member 12 are not contacted, the conical body of the movable member 12 is matched with the conical cavity of the fixed member 11 in shape, so that the conical body and the conical cavity form fit, and the vacuumizing interface 114 is arranged above the conical cavity of the fixed member 11.
The non-contact constant-diameter cavity and the cylinder do not form an abutting surface, namely the communication between the vacuumizing interface 114 and the constant-diameter cavity is always kept, and the control surface used for communicating and cutting off the vacuumizing interface 114 and the air inlet channel 113 is the conical body of the movable part 12 and the conical body of the fixed part 11.
The conical shapes matched with each other not only can ensure that the contact surface is small after the two are attached, the on-off control is convenient and sensitive, the speed is high, but also the conical inclined surface forms a allowance space for the movable piece 12 to extend into the fixed piece 11, and when the movable piece 12 moves downwards, the two are attached seamlessly.
The constant-diameter cavity and the cylinder which are not in contact do not form an attaching surface, so that contact abrasion of the fixed part and the movable part can be reduced, a control surface is not formed, the contact area of the control surface is reduced, the screwing resistance of the movable part 12 is reduced, more importantly, the attaching and bonding probability of the surface between the fixed part 11 and the movable part 12 is smaller in a long-time high-temperature vacuum environment because the control surface area is smaller, and the design defect that the movable part 12 cannot be screwed due to bonding of the fixed part and the movable part is avoided.
Referring to fig. 1 and 2, further, the upper part of the movable member 12 is in threaded connection with the top of the fixed member 11, so as to realize the micro-displacement of the movable member 12 up and down relative to the fixed member 11 by screwing the movable member 12.
Further, the fixing member 11 includes a base 111 and a connecting seat 112, the bottom of the base 111 is used for being connected with the charging bucket, the top of the base 111 is movably connected with the bottom of the connecting seat 112, a hole assembled with the movable member 12 by threads is formed in the top of the connecting seat 112, and the connecting seat 112 is in threaded connection with the base 111.
The base 111 and the connecting seat 112 which are movably connected are convenient to detach and replace, so that the cost of single parts is reduced, and compared with the product in the prior whole process, the replacement cost is lower.
Further, a cavity is formed between the connecting seat 112 and the top of the base 111, an annular flange 121 is further provided on the side wall of the movable member 12 above the top of the base 111, the outer diameter of the annular flange 121 is larger than the inner diameter of the cavity of the base 111, and the annular flange 121 has a slope inclined downward.
When the movable member 12 is in threaded connection with the connecting seat 112, the movable member 12 is repeatedly screwed for many times, the crest position of the thread of the movable member 12 or the connecting seat 112 is the most fragile part, and mechanical damage is caused by many times of operation, so that the crest of the thread is worn or broken, and therefore, fallen fragments or scraps fall downwards along the outer wall of the movable member 12, enter the cavity along the equal-diameter outer wall of the movable member 12, enter the air inlet channel 113, even enter the inside of the charging bucket, and cause pollution to sintered materials in the charging bucket.
Therefore, according to the scheme, the annular flange 121 is seamlessly connected with the outer wall of the movable piece 12, the annular flange 121 is blocked between the cavity and the threads, and even if the falling of the scraps is unavoidable, the falling scraps are received by the inclined surface of the annular flange 121, further slide down along the inclined surface and are in the connecting seat 112 to be collected, so that the pollution of the materials entering the charging bucket is avoided.
Further, the fixing member 11 is made of stainless steel, and the movable member 12 is made of graphite.
When the high-temperature vacuum sintering furnace is used, the temperature in the furnace reaches 1000 ℃ or even higher, when the material inside the charging bucket is sintered, frequent vacuumizing operation is needed to be carried out on the inside of the charging bucket, and the vacuumizing interface 114 is needed to be opened and closed for a plurality of times, but in a high-temperature environment, as the thread between the movable piece 12 and the fixed piece 11 is connected, the thread tip part is weakest in bearing high-temperature capability due to smaller thickness and is easily melted at high temperature or becomes low in strength, so that the phenomenon that the thread tip part between the movable piece 12 and the fixed piece 11 is adhered and melted into a whole is caused, thus, when the movable piece 12 is screwed strongly, the thread tip part or the thread root part is damaged, the thread structure is destroyed, and the movable piece 12 cannot rotate relative to the fixed piece 11, and the vacuumizing interface 114 cannot be opened.
Therefore, the movable part 12 is replaced by graphite material in the scheme, the high temperature resistance is fully improved, the high temperature resistance reaches more than 2500 ℃, the melting of the thread tooth tip part of the movable part 12 caused by high temperature is avoided, and even if the thread tooth tip of the fixed part 11 is melted at high temperature, the problem of fusion bonding of the movable part and the graphite is solved due to poor combination of the movable part and the graphite.
The modules or units in the device of the embodiment of the invention can be combined, divided and deleted according to actual needs.
The foregoing disclosure is illustrative of the preferred embodiments of the present invention, and is not to be construed as limiting the scope of the invention, as it is understood by those skilled in the art that all or part of the above-described embodiments may be practiced with equivalents thereof, which fall within the scope of the invention as defined by the appended claims.
