[0004] The utility model discloses a rectangular ring sintering fixture, including bottom plate, be equipped with multiple partition strips on the bottom plate, constitute rectangular ring accommodating groove between two adjacent partition strips, both ends of multiple partition strips are equipped with mat strip slot, install mat strip in mat strip slot, the upper end surface of mat strip is equipped with multiple support strip slot, install support strip in support strip slot, the lower end surface of support strip is equipped with the buckle groove, the buckle groove is buckled in support strip slot, support strip is in parallel with the just above of rectangular ring accommodating groove, and multiple rectangular ring green bodies are strung on support strip.

[0005] Preferably, the width of the support strip is less than the inner circle width of the rectangular ring product.

[0006] Preferably, the width of the support strip slot is greater than the width of the support strip.

[0007] Preferably, the width of the mat strip slot is greater than the width of the mat strip.

[0008] Preferably, the material of the support strip, the mat strip and the bottom plate is high-temperature-resistant ceramic.

[0009] The utility model discloses the beneficial effect from technical scheme is: bottom plate is used for separating green body and sintering plate, a plurality of rectangular ring accommodating grooves can separate green body, and the mat strip can prevent the shift of support strip and green body in the transfer, and the support strip is used for supporting the height direction of rectangular ring green body, avoids the collapse because of gravity effect, and meanwhile can prevent the violent shrinkage of green body in the process of sintering forming, influences product quality. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 It is the layout of example rectangular ring sintering carrier in working.

[0011] Figure number shows:

[0012] 1, bottom plate, 2, separating strip, 3, mat strip, 4, support strip, 5, rectangular ring green body. DETAILED DESCRIPTION

[0013] The utility model will be further explained in detail in connection with specific embodiment.

[0014] Embodiment:

[0015] As Figure 1 The utility model discloses a rectangular ring sintering carrier, including

[0016] Bottom plate 1, a plurality of separating strips 2 are equipped on the bottom plate 1, and rectangular ring accommodating groove is formed between two adjacent separating strips 2, and both ends of a plurality of separating strips 2 are equipped with mat strip slot, and mat strip 3 is installed in mat strip slot, and the upper end surface of mat strip 3 is equipped with a plurality of support strip slot, and support strip 4 is installed in support strip slot, and the lower end surface of support strip 4 is equipped with buckle groove, and buckle groove is buckled in support strip slot, and support strip 4 is parallelly arranged in the just above of rectangular ring accommodating groove, and a plurality of rectangular ring green bodies 5 are strung on support strip 4. The bottom plate 1 is used for separating green body and sintering plate, and a plurality of rectangular ring accommodating grooves can separate green body, and the mat strip 3 can prevent the shift of support strip 4 and green body in the transfer, and the support strip 4 is used for supporting the height direction of rectangular ring green body 5, avoids the collapse because of gravity effect, and simultaneously can prevent the violent shrinkage of green body in the process of sintering forming, influences product quality.

[0017] The width of support strip 4 is less than the inner ring width of rectangular ring finished product.
