Anti-loosening balance beam ball joint assembly structure

Abstract

This utility model discloses a balance beam ball joint assembly structure for preventing loosening, relating to the technical field of balance beam ball joint assemblies. It includes a base, a ball seat fixedly mounted on the top surface of the base, a connecting shaft mounted on the top surface of the ball seat, and a ball head mounted on the bottom end of the connecting shaft, with the ball head movably connected within the ball seat. A protective cover is fixedly mounted on the top surface of the base, and the top surface of the protective cover is connected to the outside of the connecting shaft via a conical rubber sleeve. In use, this utility model effectively connects the protective cover and the connecting shaft using a sleeve or similar device, preventing the connecting shaft from completely detaching from the protective cover. It also changes the movement space of the baffle. When the connecting shaft swings, the baffle presses against the bearing plate, thereby controlling the maximum swing angle of the connecting shaft. This ensures that after the connecting shaft swings to its maximum angle, it does not contact the opening of the ball seat, effectively preventing frequent large-angle swings that could lead to excessive wear between the outside of the connecting shaft and the ball seat, thus effectively preventing the ball head from detaching from the ball seat.

Description

Technical Field

[0001] This utility model relates to the field of balance beam ball joint assembly technology, and in particular to a balance beam ball joint assembly structure that prevents loosening. Background Technology

[0002] The balance beam ball joint assembly is a key component commonly used in engineering machinery (such as truck suspension systems and excavator chassis), industrial equipment, or robot joints. Its core function is to allow multi-degree-of-freedom motion (such as rotation and oscillation) and withstand dynamic loads.

[0003] In the application scenarios of balance beams, the commonly used ball joint type is the universal ball joint. The universal ball joint can generate displacement in any direction and achieve flexible rotation, which makes it well adaptable to the multi-directional motion requirements of balance beams under complex working conditions.

[0004] Existing universal ball joints mainly consist of a ball head, a connecting shaft, and a ball seat. The ball head moves within the ball seat, thereby enabling multi-degree-of-freedom motion of the connecting shaft. However, when universal ball joints are used under complex working conditions, the connecting shaft swings frequently and the swing angle is difficult to control. Large swings often occur, resulting in significant wear between the outer side of the connecting shaft and the opening of the ball seat, causing the opening of the ball seat to widen and posing a risk of the ball head loosening. In view of this, this application proposes a balance beam ball joint assembly structure to prevent loosening. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-loosening balance beam ball hinge assembly structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ball joint assembly structure with anti-loosening balance beam includes a base, a ball seat fixedly mounted on the top surface of the base, a connecting shaft mounted on the top surface of the ball seat, a ball head mounted on the bottom end of the connecting shaft, and the ball head movably connected within the ball seat. A protective cover is fixedly mounted on the top surface of the base, and the top surface of the protective cover is connected to the outside of the connecting shaft via a conical rubber sleeve. A second fixing plate is fixedly mounted on the outside of the connecting shaft, and a first fixing plate is fixedly mounted on the outside of the protective cover. Multiple second fixing rings are fixedly mounted on the bottom surface of the second fixing plate, and multiple first fixing rings are fixedly mounted on the top surface of the first fixing plate. A sleeve is installed between the second fixed ring and the corresponding first fixed ring. A second movable collar is movably connected to the outside of each sleeve, and each second movable collar is fitted inside the corresponding first fixed ring. A baffle and a bearing plate are slidably connected inside each sleeve. A connecting shaft is fixedly installed on the outside of each baffle. The top end of each connecting shaft is movably connected to the second fixed ring through the first movable collar. A driving mechanism is provided inside each sleeve, and the driving mechanism drives the bearing plate to slide. A pressure plate is installed on the top end of each bearing plate through multiple spring dampers.

[0008] Preferably, each of the drive mechanisms includes a threaded rod, and each threaded rod is rotatably connected to the bottom wall of the sleeve at a corresponding position. Each threaded rod is threaded with a threaded sleeve, and the top end of each threaded sleeve is fixedly connected to the bottom surface of the bearing plate at a corresponding position. A knob is installed at the bottom end of each threaded rod.

[0009] Preferably, a fixing sleeve is fixedly installed on the top wall of each sleeve, and each connecting shaft is slidably connected to the fixing sleeve corresponding to its position, and the diameter of each baffle is greater than the diameter of the fixing sleeve.

[0010] Preferably, a limiting plate is fixedly installed at the top end of each threaded rod, and the diameter of each limiting plate is greater than the diameter of the threaded rod.

[0011] Preferably, multiple guide rails are symmetrically installed on the inner wall of each sleeve, and each threaded sleeve is slidably connected to the guide rail corresponding to its position.

[0012] Preferably, a connecting flange is fixedly installed at the bottom of the protective cover, and the connecting flange is fixedly installed on the bottom surface of the base by multiple bolts.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, through a first movable collar, a second movable collar, a sleeve, a first fixed ring, a second fixed ring, a bearing plate, a drive mechanism, a baffle, a connecting shaft, and other devices, achieves effective connection between the protective sleeve and the connecting shaft via the sleeve and other devices, preventing the connecting shaft from completely detaching from the protective sleeve. Furthermore, the drive mechanism can drive the bearing plate to slide within the sleeve and limit the bearing plate to that position, thereby changing the movement space of the baffle. When the connecting shaft swings, the baffle squeezes the bearing plate, thereby controlling the maximum swing angle of the connecting shaft. After the connecting shaft swings to the maximum angle, it does not contact the opening of the ball seat, effectively avoiding frequent large-angle swings of the connecting shaft, which would lead to excessive wear between the outer side of the connecting shaft and the ball seat, thus effectively preventing the ball head from detaching from the ball seat.

[0015] 2. This utility model, through protective sleeves, conical rubber sleeves and other devices, enables the protective cover and conical rubber sleeve to hide and protect the ball head and ball seat, reducing the entry of external dust into the gap between the ball head and ball seat, reducing wear between the ball head and ball seat, and the setting of the conical rubber sleeve does not affect the normal movement of the connecting shaft.

[0016] 3. This utility model, through devices such as pressure plates and spring dampers, enables the spring dampers and pressure plates at the top of the bearing plate to function when the connecting shaft swings at a large angle, effectively reducing the impact force of the baffle and ensuring structural stability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] This utility model provides a technical solution: such as Figure 1-5 As shown, the anti-loosening balance beam ball joint assembly structure includes a base 1, a ball seat 8 fixedly installed on the top surface of the base 1, a connecting shaft 5 installed on the top surface of the ball seat 8, a ball head installed at the bottom end of the connecting shaft 5, and the ball head is movably connected inside the ball seat 8. A protective cover 2 is fixedly installed on the top surface of the base 1, and the top surface of the protective cover 2 is connected to the outside of the connecting shaft 5 through a conical rubber sleeve 7.

[0025] The protective cover 2 and the conical rubber sleeve 7 can conceal and protect the ball head and ball seat 8, reducing the entry of external dust into the gap between the ball head and ball seat 8, thus reducing wear between the ball head and ball seat 8. Furthermore, the conical rubber sleeve 7 does not affect the normal movement of the connecting shaft 5.

[0026] A second fixing plate 6 is fixedly installed on the outer side of the connecting shaft 5, and a first fixing plate 4 is fixedly installed on the outer side of the protective cover 2. Multiple second fixing rings 11 are fixedly installed on the bottom surface of the second fixing plate 6, and multiple first fixing rings 9 are fixedly installed on the top surface of the first fixing plate 4. A sleeve 10 is installed between each second fixing ring 11 and the corresponding first fixing ring 9. A second movable collar 14 is movably connected to the outer side of each sleeve 10, and each second movable collar 14 is fitted into the corresponding first fixing ring 9. A baffle 16 and a bearing plate 22 are slidably connected in each sleeve 10. A connecting shaft 12 is fixedly installed on the outer side of each baffle 16. The top end of each connecting shaft 12 is movably connected to the second fixing ring 11 through a first movable collar 13. A driving mechanism is provided in each sleeve 10, and the driving mechanism drives the bearing plate 22 to slide. A pressure plate 24 is installed on the top end of each bearing plate 22 through multiple spring dampers 23.

[0027] It should be noted that both the first movable collar 13 and the second movable collar 14 are provided with openings that can be opened and closed, which facilitates the fitting of the first movable collar 13 and the second movable collar 14. Furthermore, the drive mechanism can drive the bearing plate 22 to slide within the sleeve 10, thereby changing the activity space of the baffle 16 and controlling the maximum swing angle of the connecting shaft 5. This avoids frequent large swing angles of the connecting shaft 5, which would cause excessive wear between the outer side of the connecting shaft 5 and the ball seat 8, leading to the ball head detaching. In addition, the impact force of the baffle 16 can be reduced by the spring damper 23 and the pressure plate 24.

[0028] Furthermore, each drive mechanism includes a threaded rod 19, and each threaded rod 19 is rotatably connected to the bottom wall of the corresponding sleeve 10. Each threaded rod 19 is threadedly connected to a threaded sleeve 20, and the top end of each threaded sleeve 20 is fixedly connected to the bottom surface of the corresponding bearing plate 22. Each threaded rod 19 is equipped with a knob 18 at its bottom end. The knob 18 can drive the threaded rod 19 to rotate, thereby causing the threaded sleeve 20 to slide. It should be noted that the thread has self-locking properties, so when the knob 18 stops rotating, the position of the threaded sleeve 20 is fixed.

[0029] Furthermore, a fixed sleeve 15 is fixedly installed on the top wall of each sleeve 10, and each connecting shaft 12 is slidably connected to the fixed sleeve 15 corresponding to its position. The diameter of each baffle 16 is greater than the diameter of the fixed sleeve 15. The fixed sleeve 15 can block the baffle 16, restricting the range of motion of the baffle 16, and the fixed sleeve 15 can guide and limit the connecting shaft 12.

[0030] Furthermore, a limiting plate 21 is fixedly installed at the top of each threaded rod 19, and the diameter of each limiting plate 21 is greater than the diameter of the threaded rod 19 to prevent the threaded sleeve 20 from disengaging from the threaded rod 19.

[0031] Furthermore, multiple guide rails 17 are symmetrically installed on the inner wall of each sleeve 10, and each threaded sleeve 20 is slidably connected to the guide rail 17 corresponding to its position. By limiting the threaded sleeve 20, it cannot rotate and can only slide linearly.

[0032] Furthermore, a connecting flange 3 is fixedly installed at the bottom of the protective cover 2. The connecting flange 3 is fixedly installed on the bottom surface of the base 1 by multiple bolts, which facilitates the disassembly and assembly of the protective cover 2.

[0033] This utility model provides a balance beam ball joint assembly structure to prevent loosening. The specific working principle is as follows: First, the protective cover 2 and the conical rubber sleeve 7 form a protective barrier to hide the ball head and the ball seat 8, effectively blocking external dust from entering the gap between them and reducing wear. At the same time, the conical rubber sleeve 7 does not affect the normal movement of the connecting shaft 5.

[0034] When the connecting shaft 5 swings, the baffle 16 moves within the sleeve 10 through the cooperation of the first fixing plate 4, the second fixing plate 6, the first fixing ring 9, the second fixing ring 11 and the sleeve 10. At the same time, the connection of the sleeve 10 can prevent the connecting shaft 5 from completely detaching from the ball seat 8.

[0035] Furthermore, the rotatable knob 18 drives the threaded rod 19 to rotate, thereby causing the threaded sleeve 20 to slide, which in turn moves the bearing plate 22, changing the activity space of the baffle 16. This limits the maximum swing angle of the connecting shaft 5, preventing excessive wear between the outer side of the connecting shaft 5 and the ball seat 8 due to excessive swing angle, and effectively preventing the ball head from detaching.

[0036] When the connecting shaft 5 swings at a large angle, the spring damper 23 and pressure plate 24 at the top of the bearing plate 22 play a role in effectively reducing the impact force of the baffle 16 and ensuring structural stability.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
