Description

Technical Field

[0001] This utility model relates to the field of hydraulic system technology, and in particular to a connecting bracket for a hydraulic system pressure rod. Background Technology

[0002] In modern industrial production, hydraulic systems are widely used in various mechanical equipment due to their advantages such as high output force, smooth transmission, and high control precision. As an important component of the hydraulic system, the pressure rod plays a crucial role in transmitting and converting hydraulic power. The connecting frame, as the connection hub between the pressure rod and other components, directly affects the stability and reliability of the entire hydraulic system.

[0003] The existing connecting frame is inconvenient to install and disassemble, which not only increases the maintenance cost and time of the equipment, but may also damage the connecting frame due to frequent disassembly, further affecting the normal operation of the hydraulic system.

[0004] Meanwhile, due to the different sizes of the fixing rods used to fix the pressure rod, the existing connecting brackets have poor versatility and cannot quickly ensure that the fixing rod is in the center of the fixing hole. This can easily cause displacement when fixing the pressure rod, affecting the fixing effect of the pressure rod.

[0005] Therefore, it is necessary to design a connector for the pressure rod of a hydraulic system to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a connecting frame for a hydraulic system pressure rod. This connecting frame, through the setting of a pre-fixing component, can pre-fix the fixing frame and the fixing block before connecting them, so that the bolts do not need to be held by hand, making the installation and disassembly operations easier. Furthermore, through the setting of the positioning block, it can be ensured that the fixing rod is located at the center of the fixing hole when the connecting frame is sleeved on the fixing rod.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A connecting bracket for a hydraulic system pressure rod includes a fixing bracket. The fixing bracket has a fixing block on its left side, the fixing block being arc-shaped. The left side of the fixing bracket has an arc-shaped groove and multiple fixing screw holes. The fixing block has multiple connecting screw holes that mate with the fixing screw holes, and each connecting screw hole is threaded with a bolt. The right side of the fixing bracket has an arc-shaped block, and a fixing round hole is provided between the arc-shaped block and the fixing bracket.

[0009] Preferably, the arc-shaped block and the fixing frame are integrally formed.

[0010] Preferably, the fixing frame and the fixing block are provided with embedding grooves on both the upper and lower sides, and each embedding groove is provided with a threaded hole.

[0011] Preferably, a pre-fixing assembly is provided between the fixing frame and the fixing block. The pre-fixing assembly includes rectangular blocks arranged on the front and rear sides of the fixing frame. Each of the two rectangular blocks has a round hole. Each of the front and rear sides of the fixing block is fixedly connected to a connecting plate. Each of the two connecting plates is fixedly connected to a fixing pin on its right side.

[0012] Preferably, a rubber sleeve is provided inside both of the circular holes.

[0013] Preferably, a plurality of telescopic rods are fixedly connected to the inner wall of the fixed circular hole, and each telescopic end of the plurality of telescopic rods is fixedly connected to a positioning block. The plurality of positioning blocks are elastically connected to the inner wall of the fixed circular hole by springs.

[0014] Compared with existing technologies, the advantages of this device are:

[0015] 1. Compared with the existing technology, the device can pre-fix the fixing frame and fixing block when connecting them by setting the pre-fixing components, so that the bolts do not need to be held by hand, which greatly facilitates the installation and disassembly operation, effectively improves work efficiency and reduces labor intensity.

[0016] 2. Compared with the prior art, this device sets multiple telescopic rods and positioning blocks on the inner wall of the fixed circular hole, and the positioning blocks are elastically connected to the inner wall of the fixed circular hole by springs. This ensures that when the connecting frame is sleeved on the fixed rod, the fixed rod is located at the center of the fixed circular hole, thereby achieving precise positioning of the fixed rod, improving the reliability and stability of the connection, and ensuring the normal and efficient operation of the hydraulic system.

[0021] 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.

[0022] Reference Figures 1-3 A connecting bracket for a hydraulic system pressure rod includes a fixed bracket 1. A fixed block 2 is provided on the left side of the fixed bracket 1. The fixed block 2 is arc-shaped. An arc-shaped groove is provided on the left side of the fixed bracket 1. Multiple fixing screw holes 15 are provided on the left side of the fixed bracket 1. Multiple connecting screw holes that mate with the fixing screw holes 15 are provided on the fixed block 2. A bolt 9 is threaded into each connecting screw hole. An arc-shaped block 3 is provided on the right side of the fixed bracket 1. A fixing round hole is provided between the arc-shaped block 3 and the fixed bracket 1. The arc-shaped block 3 and the fixed bracket 1 are integrally formed. The thickness of the arc-shaped block 3 is less than the thickness of the fixed bracket 1.

[0023] The fixing frame 1 and the fixing block 2 are provided with embedding grooves 4 on both the upper and lower sides, and each embedding groove 4 is provided with a threaded hole 6, so that some connecting parts (such as bearings) can be installed on the outside of the pressure rod.

[0024] The fixing frame 1 and the fixing block 2 are provided with a pre-fixing component. The pre-fixing component includes rectangular blocks 7 on the front and rear sides of the fixing frame 1. Each rectangular block 7 has a round hole. Each of the front and rear sides of the fixing block 2 is fixedly connected to a connecting plate 11. Each of the two connecting plates 11 is fixedly connected to a fixing pin 8 on the right side. Each of the two round holes is provided with a rubber sleeve 10. The friction between the rubber sleeve 10 and the fixing pin 8 makes it difficult for the fixing pin 8 to move after insertion, thereby initially fixing the fixing frame 1 and the fixing block 2.

[0025] The inner wall of the fixed circular hole is fixedly connected with multiple telescopic rods 12, and the telescopic ends of the multiple telescopic rods 12 are fixedly connected with positioning blocks 14. The multiple positioning blocks 14 are elastically connected to the inner wall of the fixed circular hole through springs 13, and the four positioning blocks 14 are distributed in a ring array along the inner wall of the fixed circular hole.

[0026] The functional principle of this utility model can be explained by the following operation: When the pressure rod of the hydraulic system needs to be installed, one side of the pressure rod is placed close to the inner wall of the arc-shaped groove, and then the fixing block 2 is brought close to the fixing frame 1. At this time, the fixing pins 8 on the connecting plates 11 on the front and rear sides of the fixing block 2 are aligned with the round holes in the rectangular blocks 7 on the front and rear sides of the fixing frame 1. Since there is a rubber sleeve 10 in the round hole, after the fixing pin 8 is inserted into the round hole, the rubber sleeve 10 can increase the friction, so that the fixing block 2 and the fixing frame 1 can be relatively stably pre-fixed together without manual support. In this way, when installing the bolt 9 later, it is easier to pass the bolt 9 through the connecting screw hole on the fixing block 2 and screw it into the fixing screw hole 15 on the left side of the fixing frame 1 to complete the fastening connection between the fixing frame 1 and the fixing block 2.

[0027] When the connecting frame is fitted onto the fixed rod, the structure of the fixed circular hole on the connecting frame comes into play. Multiple telescopic rods 12 are fixedly connected to the inner wall of the fixed circular hole, and each telescopic rod 12 has a positioning block 14 fixedly connected to its telescopic end. The positioning blocks 14 are elastically connected to the inner wall of the fixed circular hole via springs 13. When the pressure rod is inserted into the fixed circular hole, the pressure rod presses against the positioning blocks 14. The positioning blocks 14, under pressure, compress the springs 13 and cause the telescopic rods 12 to retract. Due to the elastic force of the springs 13, the positioning blocks 14 apply pressure evenly to the pressure rod, thereby stably positioning the pressure rod at the center of the fixed circular hole, ensuring accurate connection between the pressure rod and the connecting frame, and guaranteeing stable pressure transmission in the hydraulic system.

[0028] 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.
