Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention provides a pressure resistance testing device for an insulating tie rod, comprising a base 1, with support frames 4 on both sides above the base 1, and a middle support seat 2 and a top plate 3 respectively between the middle and top of the support frames 4. Support columns 11 are inserted in the middle of the base 1 and the middle support seat 2, and a lower support plate 8 is provided on the top of the support column 11. A gear component 12 is sleeved on the middle of the support column 11, and a turntable 13 is provided on one side of the gear component 12. A motor 14 and a positioning frame 15 are respectively provided below the turntable 13. A telescopic cylinder assembly 5 is inserted below the middle of the top plate 3, and a lower pressure plate 6 is provided at the bottom of the telescopic cylinder assembly 5. A transparent protective cover 7 is installed below the lower pressure plate 6.

[0023] In this embodiment, the bottom of the rotating connection support column 11 is inserted into the middle of the upper part of the base 1, and the upper part of the support column 11 extends out of the middle of the rotating connection support seat 2, while the top of the support column 11 is flush with the top of the middle support seat 2.

[0024] Furthermore, the top of the support column 11 is inserted into the middle of the bottom of the fixed connection of the lower support plate 8, and the bottom of the lower support plate 8 is rotatably connected to the top of the middle support seat 2.

[0025] A support column 11 is inserted into the base 1 and the middle support seat 2. The support column 11 rotates in the base 1 and the middle support seat 2 under the action of external force. At the same time, the lower support plate 8 provided on the top of the support column 11 also rotates.

[0026] Furthermore, the lower support plate 8 is provided with a plurality of ring grooves 9 and a plurality of placement grooves 10, and the placement grooves 10 are placed inside the ring grooves 9.

[0027] Furthermore, an insulating pull rod is installed inside the placement groove 10, and multiple ring grooves 9 are equally spaced above the lower support plate 8 along with the placement groove 10.

[0028] Multiple placement slots 10 are provided above the lower support plate 8, so that multiple insulating tie rods can be tested above the lower support plate 8.

[0029] Furthermore, an internal cylindrical groove 701 is formed between the transparent protective cover 7 and the lower pressure plate 6, and the transparent protective cover 7 corresponds to the ring groove 9, while the internal cylindrical groove 701 corresponds to the placement groove 10.

[0030] The transparent protective cover 7 located below the lower pressure plate 6 corresponds to the groove 9 on the lower support plate 8. After the insulating pull rod is placed in the groove 10, the lower pressure plate 6 is pressed down against the lower support plate 8 for testing. At the same time, the transparent protective cover 7 is inserted into the groove 9 to protect the outside of the insulating pull rod.

[0031] In this embodiment, the middle part of the gear component 12 is fixedly connected by the outer sleeve of the middle part of the support column 11, and the tooth part 1301 is fixedly connected to the side of the turntable 13, while the tooth part 1301 meshes with the side of the gear component 12.

[0032] After a toothed part 1301 is provided on one side of the turntable 13, the motor 14 drives the turntable 13 to rotate. The toothed part 1301 will intermittently mesh with the side of the gear component 12, causing the gear component 12 to rotate intermittently, and at the same time driving the support column 11 and the lower support plate 8 to rotate intermittently.

[0033] In this embodiment, a controller 16 is provided above one side of the support frame 4, and the controller 16 is connected to the telescopic cylinder assembly 5 and the motor 14.

[0034] Working principle:

[0035] Support frames 4 are provided on both sides above the base 1, and the middle support seat 2 and top plate 3 are respectively provided in the middle and top of the support frame 4, so that the base 1, the middle support seat 2, the top plate 3 and the support frame 4 are integrated. A lower support plate 8 is provided above the middle support seat 2, and multiple placement slots 10 are opened on the lower support plate 8 to place insulating rods. Multiple insulating rods can be placed equally on the lower support plate 8 for simultaneous testing. A telescopic cylinder assembly 5 is provided on the top plate 3, and a lower pressure plate 6 is provided below the telescopic cylinder assembly 5. Under the action of the controller 16, the telescopic cylinder assembly 5 drives the lower pressure plate 6 downward to apply pressure to the insulating rod and perform testing. Multiple ring grooves 9 are provided on the lower support plate 8, and multiple transparent protective covers 7 are provided below the lower pressure plate 6 corresponding to the ring grooves 9. When the lower pressure plate 6 descends, the lower part of the transparent protective cover 7 will be inserted into the ring groove 9, so that the transparent protective cover 7 covers the outside of the insulating rod, so that the insulating rod will not break out in the event of breakage.

[0036] In addition, a gear 12 is provided in the middle of the support column 11, and the gear 12 is placed between the base 1 and the middle support seat 2. A positioning frame 15 is provided on one side of the base 1, and a motor 14 is fixed inside the positioning frame 15. At the same time, the turntable 13 connected above the motor 14 has a toothed part 1301 on its side. The toothed part 1301 engages with the side of the gear 12. Since the toothed part 1301 is only partially engaged, it will intermittently engage with the gear 12 when rotating. This also causes the gear 12 to rotate intermittently, and the support column 11 and the lower support plate 8 to rotate intermittently. When the lower support plate 8 rotates intermittently, each of the placement slots 10 has a placement time.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
