Description

Technical Field

[0001] This utility model relates to the field of pendulum instrument technology, and in particular to a shock-type standard pendulum instrument. Background Technology

[0002] The impact-type standard pendulum vibrator is suitable for screening and analyzing materials in laboratories of highway, construction, geological and metallurgical research departments. Each start-up takes only a short time, making it convenient and simple to complete the grading work. The entire structure consists of a motor control box, a swing base, a screen clamping plate, and a screen sleeve.

[0003] In the prior art, there is a shock-type standard pendulum tester with a stable success rate. It includes a base and a collection screen. A screen support is vibrating on the base, and three sliding sleeve rods are provided on the screen support. The collection screen includes multiple screen discs stacked in sequence and a top cover. The top cover is slidably mounted on the sliding sleeve rods. The screen discs are stacked in sequence on the screen support. After the top cover slides, it covers the topmost screen disc and is locked and fixed to the sliding sleeve rods by bolts, thereby fixing the entire collection screen.

[0004] However, in actual use, the screen clamping disc is usually fixed to the sliding sleeve rod by three bolts on the outside. The bolts are tightened in sequence so that the bolts press against the sliding sleeve rod to complete the locking. However, because the locking area is small and the vibration is relatively violent during the use of the vibrator, it is easy to cause the top cover to shake, resulting in the bolts wearing on the sliding sleeve rod. Therefore, the stability of the locking and fixing of the top cover of the aggregate screen is poor during long-term use. Utility Model Content

[0005] To improve the stability of the locking and fixing of the top cover during long-term use, this application provides a shock-type standard pendulum device.

[0006] The shock-type standard pendulum meter provided in this application adopts the following technical solution: A shock-type standard pendulum apparatus includes a base, a vibrating seat, several sieve trays, and a top cover. The sieve trays are stacked on the vibrating seat, which is movably mounted on the base. The vibrating seat is equipped with a sliding screw. The top cover is rotatably equipped with an mounting ring, which is fitted onto the sliding screw and threadedly connected to it. The top cover is equipped with a rotating assembly for driving the mounting ring to rotate. The top cover is rotatably equipped with a locking bolt for abutting against the sliding screw to lock the top cover.

[0007] By adopting the above technical solution, during use, the rotating component drives the mounting ring to rotate, causing the top cover to slide on the sliding screw. When the top cover is closed, the rotating component drives the mounting ring to rotate until the top cover slides onto the screen plate. At this time, the mounting ring and the sliding screw are locked together by threads, thereby improving the stability of the connection between the top cover and the sliding screw, reducing the probability of the top cover swaying up and down or left and right relative to the sliding screw during device vibration, and distributing the pressure on the locking bolt through the threads of the sliding screw, thereby reducing the degree of wear of the locking bolt on the sliding screw, and improving the stability of the locking and fixing of the top cover during long-term use.

[0008] Preferably, the rotating assembly includes a rotating wheel, a first rotating gear, a second rotating gear, and a third rotating gear. The upper cover is provided with a rotating seat, and the rotating seat is provided with a rotating cavity. The mounting ring is rotatably disposed in the rotating cavity. The sliding screw passes through the rotating seat. The first rotating gear, the second rotating gear, and the third rotating gear are all rotatably disposed in the rotating cavity. The rotating wheel is rotatably disposed on the rotating seat. The first rotating gear is connected to the rotating seat. The third rotating gear is sleeved on the mounting ring. The second rotating gear is meshed between the first rotating gear and the third rotating gear.

[0009] By adopting the above technical solution, the rotating wheel is driven to rotate, thereby driving the first rotating gear to rotate. The second transmission gear meshes with the third transmission gear, thereby driving the mounting ring to rotate so that it can slide on the sliding screw. The operation is simple and convenient, and easy to use.

[0010] Preferably, the sliding screw, locking bolt and mounting ring are provided in multiple sets, and the second rotating gear and the third rotating gear are provided in multiple sets.

[0011] By adopting the above technical solution, multiple sets of sliding screws, locking bolts and mounting rings are set to improve the stability of the sliding and locking of the top cover.

[0012] Preferably, the rotating seat is further provided with a transmission assembly, which is used to drive multiple locking bolts to rotate synchronously.

[0013] By adopting the above technical solution, the transmission component is used to drive multiple locking bolts to rotate synchronously, thereby locking and fixing the top cover, reducing operation steps and improving ease of use.

[0014] Preferably, the transmission assembly includes a transmission wheel, a first transmission bevel gear, a plurality of second transmission bevel gears, a plurality of first transmission gears, and a plurality of second transmission gears. The transmission wheel is rotatably mounted on a rotating seat. The first transmission bevel gear is rotatably mounted in a rotating cavity and connected to the transmission wheel. The second transmission bevel gear is rotatably mounted in the rotating cavity and meshes with the first transmission bevel gear. The first transmission gear is rotatably mounted in the rotating cavity and connected to the second transmission bevel gear. The second transmission gear is mounted on a locking bolt and meshes with the first transmission gear.

[0015] By adopting the above technical solution, the transmission wheel is driven to rotate, thereby driving the first transmission bevel gear to rotate, which in turn drives each second transmission bevel gear to rotate, thereby driving each first transmission gear to rotate. Through the meshing of the second transmission gears, the locking bolts are driven to rotate synchronously, thus realizing transmission. The operation is simple and convenient.

[0016] Preferably, both the locking bolt and the second transmission gear are disposed within the rotating cavity, and a locking block is disposed within the rotating cavity. The locking bolt passes through the locking block and is threadedly connected to the locking block.

[0017] By adopting the above technical solution, the locking bolt and the second transmission gear reduce the probability of the locking bolt being damaged by external object collisions, and reduce the probability of the locking bolt sliding screw being worn by external object collisions, thus reducing the locking stability and improving the stability of the top cover locking fixation during long-term use.

[0018] Preferably, the second transmission gear is mounted on the locking bolt nut.

[0019] By adopting the above technical solution, the second transmission gear is set on the locking bolt nut, which reduces the probability of the second transmission gear interfering with the rotation of the locking bolt and improves the stability of use.

[0020] Preferably, both the rotating wheel and the transmission wheel are provided with several protrusions to facilitate rotation.

[0021] By adopting the above technical solution, both the rotating wheel and the transmission wheel are provided with several protrusions, which makes it convenient for users to drive the rotating wheel and the transmission wheel to rotate during use, thus improving the ease of use.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a base, vibrating seat, screen plate, top cover, sliding screw, rotating assembly, mounting ring, and locking bolt, the screen plate is placed into the vibrating seat of the base in sequence. The mounting ring is rotated by the rotating assembly, which drives the top cover to slide along the sliding screw until the top cover slides onto the screen plate. At the same time, the mounting ring and the sliding screw are locked together by threads, thereby improving the stability of the connection between the top cover and the sliding screw, reducing the probability of the top cover swaying up and down relative to the sliding screw during device vibration, and the threads of the sliding screw share the pressure borne by the locking bolt, thereby reducing the degree of wear of the locking bolt on the sliding screw, and improving the stability of the locking and fixing of the top cover during long-term use. 2. By setting up a rotating seat, a rotating cavity, a rotating wheel, a first transmission gear, a second rotating gear, and a third rotating gear, rotating the rotating wheel on the rotating seat drives the first transmission gear in the rotating cavity to rotate. With the help of the transmission of the second transmission gear, the third transmission gears are driven to rotate, thereby driving the mounting ring to rotate synchronously. The upper cover is driven to slide up and down through the thread of the sliding screw. The operation is simple and convenient, and easy to use. 3. By setting up a transmission wheel, a first transmission bevel gear, a second transmission bevel gear, a first transmission gear, and a second transmission gear, the rotation of the transmission wheel drives the first transmission bevel gear to rotate, which in turn drives each of the second transmission bevel gears to rotate, which in turn drives each of the first transmission gears to rotate, thereby meshing and driving the second transmission gears on each locking bolt to rotate, so as to synchronously drive each locking bolt to rotate. The operation is simple and convenient, and easy to use. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses an impact-type standard pendulum apparatus. (Refer to...) Figure 1 and Figure 2 The device includes a base 1, a vibrating seat 2, several screen plates 23, and a top cover 31. The vibrating seat 2 is movably mounted on the base 1 via springs and a vibrating shaft, and the base 1 is equipped with a vibrating motor 11 for driving the vibrating seat 2 to vibrate. Three sliding screws 22 (the screw threads are not shown in detail) are vertically arranged on the surface of the vibrating seat 2. A rotating seat 3 is mounted on the top cover 31, through which the sliding screws 22 movably pass. Three mounting rings 33, each threadedly connected to one of the sliding screws 22, are rotatably mounted on the rotating seat 3. A rotating assembly 4 is provided on the rotating seat 3 to drive the mounting rings 33 to rotate. Three locking bolts 322 are rotatably mounted on the rotating seat 3 to lock the top cover 31 against the sliding screws 22. A transmission assembly 5 is provided on the rotating seat 3 to drive the locking bolts 322 to rotate synchronously. Four positioning rods 21 are also provided on the surface of the vibrating seat 2, and positioning blocks 211, each connected to one of the sliding screws 22, are fixedly mounted on the positioning rods 21. The mounting ring 33 is threadedly engaged with the sliding screw 22, which improves the stability of the connection between the top cover 31 and the sliding screw 22. The threads of the sliding screw 22 share the pressure borne by the locking bolt 322, thereby reducing the degree of wear of the locking bolt 322 on the sliding screw 22 and improving the stability of the locking and fixing of the top cover 31 during long-term use.

[0028] For ease of use, please refer to Figure 1 and Figure 2 The rotating assembly 4 includes a rotating wheel 41, a first rotating gear 42, several second rotating gears 43, and three third rotating gears 44. A rotating cavity 32 is provided inside the rotating seat 3, and a mounting ring 33 is rotatably disposed inside the rotating cavity 32. Several protrusions are provided on the outer wall of the rotating wheel 41 to facilitate rotation, and the rotating wheel 41 is rotatably disposed on the top wall of the center of the rotating seat 3. The first rotating gear 42 is rotatably disposed at the center of the rotating cavity 32 and is coaxially and fixedly connected to the rotating wheel 41. The third rotating gears 44 are fixedly sleeved on the mounting ring 33. The second rotating gears 43 mesh one-to-one, with the second rotating gears 43 at both ends meshing with the first rotating gear 42 and the second rotating gear 43 respectively. Rotating the rotating wheel 41 drives the first transmission gear 53 inside the rotating cavity 32 to rotate, and the second transmission gears 54 drive the third transmission gears to rotate, thereby driving the mounting ring 33 to rotate synchronously. The upper cover 31 slides up and down through the thread of the sliding screw 22, making operation simple, convenient, and easy to use.

[0029] For ease of use, please refer to Figure 1 and Figure 2The transmission assembly 5 includes a transmission wheel 55, a first transmission bevel gear 51, three second transmission bevel gears 52, three first transmission gears 53, and three second transmission gears 54. The transmission wheel 55 is rotatably disposed at the center of the surface of the rotating seat 3 and located below the rotating wheel 41. The side wall of the transmission wheel 55 is provided with several protrusions to facilitate rotation. The first transmission bevel gear 51 is rotatably disposed at the center of the rotating cavity 32 and located directly above the first rotating gear 42. The first transmission bevel gear 51 and the rotating wheel 41 are coaxially connected by a rotating shaft, and the first transmission bevel gear 51, the rotating wheel 41, and the rotating shaft connecting them are all penetrated by the rotating shaft of the first rotating gear 42 and the rotating shaft. The second transmission bevel gears 52 and the first transmission gears 53 are coaxially connected and are both rotatably disposed within the rotating cavity 32. The second transmission bevel gears 52 mesh with the first transmission bevel gears 51. A locking block 321 is fixedly installed on the inner wall of the rotating cavity 32. A locking bolt 322 is rotatably mounted on the locking block 321 and threadedly connected to it. The second transmission gear 54 has a certain thickness and is fixedly mounted on the nut of the locking bolt 322 and meshes with the first transmission gear 53. The rotation of the transmission wheel 55 drives the first transmission bevel gear 51 to rotate, which in turn drives the second transmission bevel gear to rotate. Through the meshing of the first transmission gear 53, the second transmission gear 54 on each locking bolt 322 rotates, so as to synchronously drive each locking bolt 322 to rotate and abut against the sliding screw 22. The operation is simple and convenient, and easy to use.

[0030] The implementation principle of the shock-type standard pendulum device in this application embodiment is as follows: When the upper cover 31 is closed, the rotating wheel 41 drives the mounting ring 33 to rotate through the gear transmission of the rotating component 4. This, in turn, drives the rotating seat 3 to move down through the thread of the sliding screw 22, causing the upper cover 31 to be fastened onto the screen plate 23. Then, the rotating transmission wheel 55 drives the locking bolt 322 to rotate through the transmission of the gear and bevel gear of the transmission component 5 until the locking bolt 322 abuts against the sliding screw 22. This application improves the stability of the connection between the upper cover 31 and the sliding screw 22 by locking the mounting ring 33 with the thread between them, reducing the probability of the upper cover 31 swaying up and down or left and right relative to the sliding screw 22 during device vibration. The thread of the sliding screw 22 shares the pressure borne by the locking bolt 322, thereby reducing the degree of wear of the locking bolt 322 on the sliding screw 22, and improving the stability of the locking and fixing of the upper cover 31 during long-term use.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
