[0024] The present utility model will be further described below by way of embodiments, but the present utility model is not limited to the scope of the described embodiments.

[0025] As Figures 1-3 shown, a mechanical property test tooling for a socket triangle support includes a base 1; further includes: a solid vertical rod 6, the bottom end of the solid vertical rod 6 is fixedly connected with a first fixing plate 3, and the first fixing plate 3 is fixedly installed on the top surface of the base 1; a removable sliding sleeve 7, the removable sliding sleeve 7 is slidably installed on the solid vertical rod 6, and one side of the removable sliding sleeve 7 is connected to the top surface of the base 1 through a lifting driving mechanism, and the lifting driving mechanism is used to drive the removable sliding sleeve 7 to slide on the solid vertical rod 6.

[0026] As Figures 2-3 shown, as a specific technical solution, the removable sliding sleeve 7 includes a first seat body 701, a second seat body 702 and an elastic plug-in member; a sliding hole 705 is formed between the first seat body 701 and the second seat body 702, and the sliding hole 705 is in clearance fit connection with the solid vertical rod 6, and the elastic plug-in member is installed on the second seat body 702. The elastic plug-in member includes two U-shaped grip bars 704, a chute 703, a spring 708 and an insertion rod 711; the number of the chutes 703 is two, and both of the two chutes 703 are opened on one side of the second seat body 702, the two ends of the U-shaped grip bar 704 respectively penetrate through the two chutes 703, the spring 708 is arranged inside the chute 703, the two U-shaped grip bars 704 are elastically connected through the spring 708, insertion rods 711 are fixedly installed at both ends of the U-shaped grip bar 704, a side groove 709 is opened on one side of the first seat body 701 close to the second seat body 702, insertion holes 710 are opened at both the upper and lower ends of the side groove 709, the end of the U-shaped grip bar 704 is inserted into the side groove 709, and the insertion rod 711 is fitted and installed in the insertion hole 710.

[0027] The removable sliding sleeve 7 is composed of a first seat body 701 and a second seat body 702, and the two are connected through an elastic plug-in member, so that the disassembly and installation between the two are convenient, thereby facilitating the placement or disassembly of the workpiece on the solid vertical rod 6, and providing convenience for the overall use.

[0028] As Figure 3 shown, a guide rod 706 is fixedly installed inside the chute 703. A guide hole 707 is formed on the U-shaped grip rod 704, and the guide rod 706 is connected with the guide hole 707 in a clearance fit manner.

[0029] Through the arrangement of the guide rod 706 and the guide hole 707, it provides guidance for the movement of the U-shaped grip rod 704.

[0030] As Figure 1 shown, as a specific technical solution, the lifting drive mechanism includes a telescopic rod, a hinge seat 8, a hinge shaft 9, and a second fixing plate 4. The second fixing plate 4 is fixedly installed on the top surface of the base 1. Hinge seats 8 are fixedly connected to one side of the first seat body 701 of the detachable sliding sleeve 7 and the top surface of the second fixing plate 4 respectively. Both ends of the telescopic rod are rotatably connected to the two hinge seats 8 through the hinge shaft 9. The telescopic rod includes a screw rod 11 and two square tubes 10; the two square tubes 10 are respectively threadedly connected to both ends of the screw rod 11. External threads 12 with opposite thread directions are respectively formed at both ends of the screw rod 11, and a middle hole 13 is formed in the middle of the screw rod 11. The square tube 10 is a tube body with an inner circle and an outer square. Internal threads with opposite thread directions are respectively formed on the inner pipe walls of the two square tubes 10.

[0031] The middle hole 13 provides a position for the insertion of external tools. By using a workpiece to turn the screw rod 11, the screw rod 11 can be rotated, so as to drive the detachable sliding sleeve 7 to slide on the solid vertical rod 6.

[0032] Among them, through the design of opposite spiral directions, when the screw rod 11 is rotated, the two square tubes 10 can be driven to move in opposite directions, so that the two square tubes 10 can approach or move away from each other.

[0033] As Figure 1 shown, as a specific technical solution, a plurality of support bottom plates 5 distributed in a circular array are fixedly installed around the bottom end of the solid vertical rod 6, and the bottom ends of the support bottom plates 5 are fixedly connected to the top surface of the first fixing plate 3.

[0034] The pipe fittings of the socketed triangular bracket are sleeved on the solid vertical rod 6, and the support bottom plates 5 are used for bottom support.

[0035] Foot supports 2 are fixedly installed at the four corners of the base 1; the foot supports 2 are used for overall support.

[0036] Working principle: The entire test fixture for the mechanical properties of the socketed triangular bracket can clamp and fix the socketed triangular bracket, playing a role in fixing the socketed triangular bracket and preventing it from moving up and down during the test;

[0037] The clamping operation is as follows. By holding two U-shaped grip rods 704 and pressing them, the two U-shaped grip rods 704 are made to approach each other, and at the same time, the spring 708 between them is compressed. During the process of the two U-shaped grip rods 704 approaching each other, they are guided by the guide rod 706 and the guide hole 707, and the insertion rod 711 is driven to be pulled out of the insertion hole 710. Then, the two U-shaped grip rods 704 are pulled to separate the second seat body 702 from the first seat body 701, completing the disassembly of the detachable sliding sleeve 7 and the solid vertical rod 6. Then, the second seat body 702 is pulled. Through the articulated installation of the telescopic rod, it can be flipped to separate the first seat body 701 from the solid vertical rod 6. Then, the pipe fitting of the disc buckle triangular bracket is sleeved on the solid vertical rod 6, and then the telescopic rod is flipped so that the sliding hole 705 of the first seat body 701 abuts against the rod surface of the solid vertical rod 6. Then, by holding the two U-shaped grip rods 704 and making the two U-shaped grip rods 704 approach each other, and then bringing the second seat body 702 close to the first seat body 701, the end of the U-shaped grip rod 704 is inserted into the side groove 709. Then, the two U-shaped grip rods 704 are slowly relaxed. Through the elastic force of the spring 708, the distance between the two U-shaped grip rods 704 is driven to increase, and the insertion rod 711 is inserted into the insertion hole 710 to complete the installation of the first seat body 701 and the second seat body 702. After installation, the formed sliding hole 705 cooperates with the solid vertical rod 6. Then, through an external tool, such as a strip-shaped rod, it is inserted into the middle hole 13, and the screw rod 11 is turned by the above tool. The screw rod 11 is screwed with the square pipe 10 to make the telescopic rod expand and contract, thereby driving the detachable sliding sleeve 7 to slide downward along the solid vertical rod 6, so that the distance between the detachable sliding sleeve 7 and the support bottom plate 5 is reduced until the upper and lower clamping of the fixed disc buckle triangular bracket is realized, completing the fixation. After fixation, a force is applied from one side to conduct the compressive test of the disc buckle triangular bracket;

[0038] After the test, by driving the screw rod 11 to rotate, the telescopic rod is extended, driving the detachable sliding sleeve 7 to slide upward along the solid vertical rod 6 to cancel the clamping of the disc buckle triangular bracket. Then, the first seat body 701 and the second seat body 702 are separated by the above operation, and the detachable sliding sleeve 7 is disassembled from the solid vertical rod 6. Then, the tested disc buckle triangular bracket can be removed.

[0039] The present utility model is not limited to the above embodiments. No matter what changes are made in its shape or structure, they all fall within the protection scope of the present utility model. The protection scope of the present utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the present utility model, but these changes and modifications all fall within the protection scope of the present utility model.
