[0003] When clamping the product to be tested, existing water pressure test fixtures usually only have two sets of symmetrical clamps installed to facilitate clamping and fixing products of different shapes. Since there are only two sets of symmetrical clamps, only the two ends of the product can be clamped and fixed, which affects the fixing effect of the product. In addition, the two sets of screws need to be rotated in sequence to clamp and fix the product, which makes it inconvenient to clamp and fix the product quickly. Utility Model Content
[0004] The purpose of the utility model is to provide a low-pressure diving platform water pressure test fixture to solve the problem raised in the above background technology that the currently used water pressure test fixture is not convenient for clamping the product stably and quickly.

[0012] Preferably, a movable block is installed at the bottom of the roller, one side of the movable block is connected to a threaded rod passing through the fixed platform, and a movable spring is connected between the rotating block and the groove of the fixed platform.
[0013] Compared with the prior art, the beneficial effect of the present invention is that when the low-pressure diving platform water pressure test fixture is in use, the test product can be placed on the rotating seat, and then the screw is rotated so that the screw drives the first connecting shaft and the first turntable to rotate through the arc block and the connecting rod. With the cooperation of the first turntable and the rotating shaft, the connecting rod can pull the sliding block to move, and the sliding block will drive the clamping block to move through the connecting block while sliding. By moving the three groups of clamping blocks close to each other, the product to be tested can be quickly clamped and fixed. At the same time, the clamping blocks in three directions can make the clamping effect of the product better, and it is convenient to quickly clamp and fix the product to be tested. This is the use feature of the low-pressure diving platform water pressure test fixture.
[0014] 1. When the low-pressure diving platform water pressure test fixture needs to clamp and fix the product to be tested, you only need to place the product on the rotating seat and then rotate the screw so that the screw drives the first connecting shaft to rotate through the arc block and the connecting rod. The rotation of the first connecting shaft will pull the sliding block to move through the cooperation of the rotating shaft and the connecting rod. At the same time, with the cooperation of the connecting block, you only need to rotate one set of screws to make the three sets of clamping blocks clamp and fix the product to be tested, thereby conveniently and quickly clamping and fixing the product to be tested.
[0015] 2. When the clamping angle of the product to be tested needs to be adjusted, the low-pressure diving platform water pressure test fixture only needs to rotate the threaded rod so that the threaded rod drives the movable block to move. The movement of the movable block will prevent the roller from squeezing the bottom of the rotating block. Then the rotating block will rotate in the opposite direction through the movable spring, so that the pressure block does not squeeze the second turntable. At this time, the second turntable can drive the rotating seat to rotate through the second connecting shaft, thereby facilitating and quickly adjusting the angle of the product to be tested.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figure 1 and Figure 3 The utility model provides a technical solution: a low-pressure diving platform water pressure test fixture, comprising: a fixed platform 1 and a clamping block 4, a rotating seat 2 is installed on the top of the fixed platform 1, the top of the rotating seat 2 is connected to a connecting block 3 through a groove, and the clamping block 4 is installed on one side of the connecting block 3;
[0023] A sliding block 5 is installed at the bottom of the connecting block 3, and one side of the sliding block 5 is connected to a connecting rod 6 through a rotating shaft. The side of the connecting rod 6 away from the sliding block 5 is connected to the first turntable 7 through a rotating shaft. The middle of the first turntable 7 is connected to a first connecting shaft 8. One side of the first connecting shaft 8 is connected to a connecting rod 9 that passes through the rotating seat 2. One side of the connecting rod 9 is connected to an arc block 10 through a slide groove. One side of the arc block 10 is connected to a screw 11 through a bearing. A fixed block 12 is sleeved on the outer side of the screw 11, and the fixed block 12 is installed on one side of the rotating seat 2.
[0024] During specific implementation, the low-pressure diving platform water pressure test fixture can place the test product on the top of the rotating seat 2 when it is necessary to clamp the test product, and then rotate the screw 11. Since the screw 11 and the fixed block 12 are threadedly connected, and the screw 11 and the arc block 10 are connected through a bearing, rotating the screw 11 will drive the arc block 10 to move, and the arc block 10 is slidably connected to the slide groove of the connecting rod 9. When the arc block 10 moves, it will drive the connecting rod 9 to move through the slide groove. The connecting rod 9 is connected to the first connecting shaft 8. Therefore, when the connecting rod 9 moves, it will drive the first connecting shaft 8 to rotate. The top of the first connecting shaft 8 is also connected to the first turntable 7. When the first connecting shaft 8 When it rotates, it will drive the first turntable 7 to rotate. Three groups of connecting rods 6 are connected to the four sides of the first turntable 7 through rotating shafts, and the other end of the connecting rod 6 is connected to one side of the sliding block 5 through a rotating shaft. When the first turntable 7 rotates, the three groups of connecting rods 6 will rotate through the rotating shaft. Since the sliding block 5 is slidably connected to the rotating seat 2 through the sliding groove, when the connecting rod 6 rotates, the three groups of sliding blocks 5 can be pulled closer to each other through the rotating shaft. The movement of the sliding block 5 will drive the top clamping block 4 to move closer to each other through the connecting block 3. Therefore, only one set of screws 11 needs to be rotated to make the three groups of clamping blocks 4 quickly clamp and fix the water pressure test product at the same time, and the three groups of clamping blocks 4 can make the fixing effect better.
[0025] See Figure 1 、 Figure 2 and Figure 3 It can be seen that when in use, it is only necessary to rotate the screw 11 so that the screw 11 drives the connecting rod 9 to move through the arc block 10, and the connecting rod 9 will drive the connecting rod 6 to rotate through the first connecting shaft 8 and the first turntable 7. At the same time, the connecting rod 6 will pull the sliding block 5 to move, and drive the top connecting block 3 and the clamping block 4 to move closer to each other through the sliding block 5, thereby facilitating and quickly clamping the three sides of the test product, and also facilitating operation.
[0026] The bottom of the rotating seat 2 is connected to a second connecting shaft 13, and the outer side of the second connecting shaft 13 is sleeved with a second turntable 14. A rotating block 15 is provided on one side of the second turntable 14, and a pressure block 16 is installed on one side of the rotating block 15. A roller 17 is provided at the bottom of the rotating block 15 through an inclined surface, and a movable block 18 is installed at the bottom of the roller 17. One side of the movable block 18 is connected to a threaded rod 19 that passes through the fixed table 1, and a movable spring 20 is connected between the rotating block 15 and the groove of the fixed table 1. One side of the rotating block 15 is connected to the groove of the fixed table 1 through a rotating shaft.
[0027] In specific implementation, the low-pressure diving platform water pressure test fixture only needs to rotate the threaded rod 19 when the clamping angle of the product needs to be adjusted. Since the threaded rod 19 is threadedly connected to the fixed block 12, and one side of the threaded rod 19 is connected to the movable block 18 through a bearing, rotating the threaded rod 19 will drive the movable block 18 to move, so that the movable block 18 slides along the slide groove inside the fixed platform 1. The movement of the movable block 18 will drive the top roller 17 to move. Since the top of the roller 17 contacts the inclined surface at the bottom of the rotating block 15, when the movable block When 18 drives the roller 17 to move toward the inside of the fixed platform 1, the roller 17 does not squeeze the inclined surface at the bottom of the rotating block 15. Then, under the reset action of the movable spring 20, the rotating block 15 rotates. When the rotating block 15 rotates, it drives the side pressure block 16 to rotate upward and separates the pressure block 16 from the second turntable 14. Without the pressure block 16 squeezing and rubbing the second turntable 14, the second connecting shaft 13 can drive the top rotating seat 2 to rotate normally. By adjusting the direction of the rotating seat 2, the angle of the test product can be adjusted.
[0028] On the contrary, when the movable block 18 drives the roller 17 to move toward the outside of the fixed platform 1, the roller 17 will squeeze the inclined surface at the bottom of the rotating block 15. The bottom of the rotating block 15 will rotate through the rotating shaft on one side and squeeze the movable spring 20 on one side, and at the same time make the pressure block 16 on one side of the rotating block 15 rotate downward. The downward rotation of the pressure block 16 will produce squeezing friction on the second turntable 14, and the squeezing friction of the second turntable 14 by the pressure block 16 will make the second turntable 14 unable to rotate. The second turntable 14 cannot rotate, and the second connecting shaft 13 cannot rotate, so that the rotating seat 2 can be more stably connected to the top of the fixed platform 1, without affecting the water pressure test effect of the product.
[0029] See Figure 1 and Figure 4 It can be seen that during use, the threaded rod 19 can be rotated according to the testing requirements of the product, so that the threaded rod 19 pushes the movable block 18 and the roller 17 to move. When the roller 17 squeezes the top rotating block 15, it is acted upon by the pressure block 16, so that the second turntable 14 and the second connecting shaft 13 cannot rotate. When the roller 17 does not squeeze the top rotating block 15, the second turntable 14 and the second connecting shaft 13 can rotate normally. At this time, the testing angle of the product can be adjusted.
[0030] To sum up: when the low-pressure diving platform water pressure test fixture is in use, the fixed platform 1 can be placed in a stable position, and then the water pressure product to be tested can be placed on the rotating seat 2, and the sliding block 5 and the connecting block 3 can drive the three groups of clamping blocks 4 to move closer to each other. By moving the three groups of clamping blocks 4 closer to each other, the product to be tested can be clamped and fixed, thereby facilitating water pressure testing of the product to be tested. This is the usage feature of the low-pressure diving platform water pressure test fixture.
