Specific embodiments
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0023] Embodiment one:
[0024] Please refer to Figures 1-4 A rubber anti-falling mud pump valve body assembly, including valve body 1 and the guide frame 3 of fixed setting in the lower end of valve body 1, the outer surface of valve body 1 is sleeved with rubber 2, and the rubber 2 and valve body 1 are provided with a paste layer, the recess is set up in the inside of valve body 1, and the limit block 41 is movably set up in the recess, and the limit block 41 extends to the outside of valve body 1 and is penetrated through valve body 1, the inclined sliding groove 411 is set up in the inside of limit block 41, the first recess is set up in one side of recess, and the bevel sliding block 42 is arranged in the inclined sliding groove 411, the moving rod 43 is fixedly connected to the bottom of bevel sliding block 42, the sliding groove for the movement of moving rod 43 is penetrated through the bottom of first recess, the spring 44 is sleeved on the outside of moving rod 43, and the two ends of spring 44 are fixedly connected with bevel sliding block 42 and the inner wall of first recess respectively, the limit slot is set up in the inner side of rubber 2, and the fixed sleeve 21 is fixedly connected in the limit slot.
[0025] Specifically, the inclined angle of inclined sliding groove 411 and bevel sliding block 42 bevel surface is 45 degrees, and bevel sliding block 42 and inclined sliding groove 411 bevel surface abut;The elastic reset assembly is arranged between the limit block 41 and the inner wall of recess, and the elastic reset assembly includes the moving plate 51 slidably arranged in the recess, the telescopic rod 52 is fixedly connected between the moving plate 51 and the inner wall of recess, the first spring 53 is sleeved on the outside of telescopic rod 52, and the two ends of first spring 53 are fixedly connected with the inner wall of recess and moving plate 51 respectively.
[0026] Furthermore, without external force, the end of the limiting block 41 extends to the outside of the valve body 1. A reliable connection is achieved between the valve body 1 and the rubber 2 through an adhesive layer, and the design of the fixing sleeve 21 enhances the fixing effect of the rubber 2. When the rubber 2 is fixed, the moving rod 43 is pulled downwards by the pull plate 45. At this time, the spring 44 is in a compressed state. Since the inclined groove 411 inside the limiting block 41 and the inclined surface of the oblique slider 42 are inclined at a 45-degree angle, the oblique slider 42 will slide up and down along the inclined groove 411 as the moving rod 43 moves. During this process, the oblique slider 42 synchronously drives the limiting block 41 to move towards the groove. At this time, the moving plate 51 is subjected to force and moves inwards synchronously. The telescopic rod 52 and the first spring 53 are in a compressed state until the limiting block 41 is fully retracted. Then, the rubber 2 is fitted onto the outer surface of the valve body 1, ensuring that the limiting groove on the inner side of the rubber 2 is aligned with the limiting block 41 on the valve body 1. When it is necessary to lock the rubber 2, the pull plate 45 is released, and the oblique slider 42 is reset under the action of the spring 44. The limit block 41 moves outward synchronously and its end is inserted into the fixing sleeve 21, thereby fixing the rubber 2.
[0027] Example 2:
[0028] Please see Figures 2-3 This embodiment provides a technical solution based on embodiment one: a pull plate 45 is slidably provided at the bottom of the moving rod 43, a storage groove 11 is provided on the outer surface of the valve body 1, and the pull plate 45 is movably disposed in the storage groove 11; a T-shaped sliding groove 451 is provided on the surface of the pull plate 45, a T-shaped slider 452 is slidably provided in the T-shaped sliding groove 451, and the T-shaped slider 452 is fixedly connected to the bottom of the moving rod 43; the outer surface of the pull plate 45 is set to be arc-shaped, and a pull groove 453 is provided on the outer surface of the pull plate 45.
[0029] Furthermore, the groove 453 on the outer surface of the pull plate 45 facilitates manual pulling by the operator to adjust the position of the pull plate 45. When the pull plate 45 is fully retracted into the receiving groove 11, its arc-shaped outer surface remains flush with the outer surface of the valve body 1, forming a smooth and uniform surface. When it is necessary to disassemble or replace the rubber 2, the pull plate 45 can be manually pulled outward. At this time, the T-shaped slider 452 slides along the T-shaped groove 451 until the pull plate 45 is fully pulled out. Then, by pulling the pull plate 45 downward, the moving rod 43 is moved, causing the limiting block 41 to move inward and disengage from the fixing sleeve 21, releasing the fixing of the rubber 2, which facilitates the disassembly and replacement of the rubber 2. When the mud pump is working, the valve body 1 is subjected to the pressure of high-pressure fluid. At this time, the limiting block 41 is subjected to external pressure and tends to move inward. However, since the pull plate 45 is fully retracted into the receiving groove 11, the oblique slider 42 will press the limiting block 41 more tightly, preventing the rubber 2 from loosening or falling off.
[0030] Working principle: When installing rubber 2, the pull plate 45 is manually pulled outward. At this time, the T-shaped slider 452 slides along the T-shaped groove 451 until the pull plate 45 is fully pulled out. Then, the pull plate 45 drives the moving rod 43 to move downward. At this time, the spring 44 is in a compressed state. Since the inclined groove 411 inside the limiting block 41 and the inclined surface of the oblique slider 42 are inclined at an angle of 45 degrees, the oblique slider 42 will slide up and down along the inclined groove 411 as the moving rod 43 moves. During this process, the oblique slider 42 simultaneously drives the limiting block 41 to move towards the groove. At this time, the moving plate 51 is subjected to force and moves inward synchronously. The telescopic rod 52 and the first spring 53 are in a compressed state until the limiting block 41 is fully retracted. Then, the rubber 2 is sleeved on the outer surface of the valve body 1, ensuring that the limiting groove on the inner side of the rubber 2 is aligned with the limiting block 41 on the valve body 1. Then, the pull plate 45 is released, and the oblique slider 42 is reset under the action of the spring 44. The limit block 41 moves outward synchronously and its end is inserted into the fixing sleeve 21, thereby fixing the rubber 2.
