Description

Technical Field

[0001] The utility model relates to the technical field of transmission rods, and particularly relates to a floating reciprocating transmission rod. Background Art

[0002] The floating reciprocating transmission rod belongs to a kind of transmission element in mechanical equipment, which can drive components to perform linear reciprocating motion. It is widely used in mechanical equipment such as air-conditioning compressors, mainly used in occasions of lubricating oil transportation, and can improve the stability and service life of the compressor during operation.

[0003] The floating reciprocating transmission rod includes a shaft seat and a transmission rod body. During use, the transmission rod body and the shaft seat are an integrated structure as a whole. The movement of the transmission rod body can be driven through the control of the shaft seat. During use, the shaft seat will be connected and cooperate with other components for movement. Therefore, the shaft seat is relatively easy to wear during use. After the shaft seat wears, the size of the connection hole will change, which will cause the shaft seat to shake during use, resulting in instability during work. Since the shaft seat and the transmission rod body cannot be quickly connected in a splicing manner, when replacing, the shaft sleeve and the transmission rod body need to be replaced, and it needs to be disassembled and replaced with other components, which is inconvenient to use. To solve this technical problem, the utility model proposes a floating reciprocating transmission rod. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a floating reciprocating transmission rod, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A floating reciprocating transmission rod includes a shaft seat. A connecting rod is fixedly installed inside the shaft seat. A first limiting groove is opened inside the connecting rod. A limiting rod is slidably connected inside the first limiting groove. A fixing ring is fixedly installed on the outer surface of the limiting rod. The outer surface of the fixing ring is slidably connected with a transmission rod body. A first fixing rod and a second fixing rod are respectively fixedly installed on both sides of the fixing ring. A clamping plate is slidably connected inside both the first fixing rod and the second fixing rod. A first fixing groove is opened inside the connecting rod, and a second fixing groove is opened inside the transmission rod body.

[0007] Preferably, a fixing bolt is slidably connected inside the limiting rod, and the outer surface of the fixing bolt is threadedly connected with the inside of the connecting rod.

[0008] Preferably, the cross-section of the limiting rod is a hexagonal structure. A second limiting groove is opened inside the transmission rod body, and the outer surface of the limiting rod is slidably connected with the inside of the second limiting groove.

[0009] Preferably, support plates are fixedly installed on both sides of the fixing ring. The outer surface of the support plate is slidably connected to the inside of the connecting rod, and the outer surface of the support plate is slidably connected to the inside of the transmission rod body.

[0010] Preferably, the outer surfaces of the clamping plate and the first fixing rod are slidably connected to the inside of the connecting rod, and the outer surface of the clamping plate is slidably connected to the inside of the first fixing groove.

[0011] Preferably, the outer surfaces of the clamping plate and the second fixing rod are slidably connected to the inside of the transmission rod body, and the outer surface of the clamping plate is slidably connected to the inside of the second fixing groove.

[0012] Preferably, springs are fixedly installed inside the first fixing rod and the second fixing rod, and the other ends of the springs are fixedly installed on one side of the clamping plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, through the cooperation among the limiting rod, the fixing ring and the clamping plate, when in use, the connecting rod will be connected to the transmission rod body. The limiting rod is placed inside the first limiting groove to fix the limiting rod. At this time, the limiting rod and the connecting rod form a whole, and the limiting rod can limit the transmission rod body.

When replacing, only the fixing ring needs to be disassembled, without disassembling the integrally connected part, and the shaft seat and the transmission rod body can be replaced separately, which is convenient for replacing the damaged parts separately, realizing the function of splicing connection between the shaft sleeve and the transmission rod body.

[0015] In the utility model, by arranging components such as springs and support plates, when the connecting rod and the transmission rod body are connected, the first fixing rod and the second fixing rod will enter the inside of the first fixing groove and the second fixing groove. The spring can control the elastic movement of the clamping plate. When connecting the fixing ring, the spring can push the clamping plate to fix the transmission rod body. The support plate can limit the axial rotation of the transmission rod body, ensuring the stability when the transmission rod body is connected to the connecting rod.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figure 1 -5 shows, a floating reciprocating transmission rod includes a shaft seat 1, and a connecting rod 2 is fixedly installed inside the shaft seat 1. The connecting rod 2 is connected to the shaft seat 1 by welding. One end portion of the connecting rod 2 will enter the inside of the shaft seat 1, which can enhance the bearing capacity of the connecting part and improve the stability during overall use.

[0024] A first limiting groove 3 is provided inside the connecting rod 2, and a limiting rod 4 is slidably connected inside the first limiting groove 3. The cross-section of the limiting rod 4 is a hexagonal structure. The cooperation of the limiting rod 4 and the first limiting groove 3 can limit the rotation of the limiting rod 4. When the limiting rod 4 is fixed, the rotation of the connecting rod 2 can be fixed.

[0025] A fixing bolt 12 is slidably connected inside the limiting rod 4, and the outer surface of the fixing bolt 12 is threadedly connected to the inside of the connecting rod 2. The limiting rod 4 can be fixed inside the connecting rod 2 through the fixing bolt 12. At this time, the limiting rod 4 and the connecting rod 2 form an integral body.

[0026] A fixing ring 5 is fixedly installed on the outer surface of the limiting rod 4, and a transmission rod body 6 is slidably connected to the outer surface of the fixing ring 5. The fixing ring 5 can support the part between the transmission rod body 6 and the connecting rod 2. A second limiting groove 13 is provided inside the transmission rod body 6, and the outer surface of the limiting rod 4 is slidably connected to the inside of the second limiting groove 13. When the fixing ring 5, the connecting rod 2 and the transmission rod body 6 are connected, the limiting rod 4 will enter the inside of the second limiting groove 13. At this time, the connection between the transmission rod body 6 and the connecting rod 2 is relatively stable, and the transmission rod body 6 and the connecting rod 2 as a whole can rotate stably synchronously without separation rotation, ensuring the stability when first applying rotational force during connection.

[0027] On both sides of the fixed ring 5, a first fixing rod 7 and a second fixing rod 8 are fixedly installed respectively. The first fixing rod 7 and the second fixing rod 8 are symmetrically arranged on both sides of the fixed ring 5. There are multiple groups of the first fixing rod 7 and the second fixing rod 8 and they are symmetrically arranged. The first fixing rod 7 and the second fixing rod 8 mainly play a role in connecting the connecting rod 2 and the transmission rod body 6. On both sides of the fixed ring 5, support plates 14 are fixedly installed. The outer surface of the support plate 14 is slidably connected to the inside of the connecting rod 2, and the outer surface of the support plate 14 is slidably connected to the inside of the transmission rod body 6. The support plate 14 can play an auxiliary role for the first fixing rod 7 and the second fixing rod 8, can share the deflection force received by the first fixing rod 7 and the second fixing rod 8, and can prevent the first fixing rod 7 and the second fixing rod 8 from being damaged when receiving a large force.

[0028] A clamping plate 9 is slidably connected to the inside of both the first fixing rod 7 and the second fixing rod 8. The outer surface of the clamping plate 9 and the first fixing rod 7 is slidably connected to the inside of the connecting rod 2. A first fixing groove 10 is formed in the inside of the connecting rod 2. The outer surface of the clamping plate 9 is slidably connected to the inside of the first fixing groove 10. After the clamping plate 9 enters the inside of the first fixing groove 10, it can fix the position of the first fixing rod 7. At this time, the fixed ring 5 and the connecting rod 2 will form an integral body.

[0029] A second fixing groove 11 is formed in the inside of the transmission rod body 6. The outer surface of the clamping plate 9 and the second fixing rod 8 is slidably connected to the inside of the transmission rod body 6. The outer surface of the clamping plate 9 is slidably connected to the inside of the second fixing groove 11. Through the connection between the clamping plate 9 and the second fixing groove 11, the transmission rod body 6 and the fixed ring 5 can be connected as an integral body. At this time, through the connection between the fixed ring 5 and the clamping plate 9, the connecting rod 2 and the transmission rod body 6 will form an integral body. Both the first fixing groove 10 and the second fixing groove 11 are L-shaped structures and can fix the clamping plate 9.

[0030] Springs 15 are fixedly installed inside both the first fixing rod 7 and the second fixing rod 8. The other end of the spring 15 is fixedly installed on one side of the clamping plate 9. The spring 15 can control the elastic movement of the clamping plate 9 inside the first fixing rod 7 and the second fixing rod 8. When connecting the first fixing rod 7 and the second fixing rod 8, the clamping plate 9 will enter the inside of the first fixing rod 7 and the second fixing rod 8 under pressure. When the clamping plate 9 moves to the top of the first fixing groove 10 and the second fixing groove 11, the spring 15 can push the clamping plate 9 to move outward. At this time, the first fixing rod 7 and the second fixing rod 8 can be fixed.

[0031] When working, put the limit rod 4 into the limit groove 3, and fix the limit rod 4 in the connecting rod 2 by the fixing bolt 12. When the limit rod 4 is fixed, the fixing ring 5 will be connected with one end of the connecting rod 2, and the fixing rod 7 will enter the fixing groove 10. At this time, the spring 15 can push the clamping plate 9 to enter the top of the fixing groove 10 to fix the fixing rod 7. At this time, the fixing ring 5 and the connecting rod 2 will form a whole, and the transmission rod body 6 will be connected along the limit groove 2 13 and the edge line of the limit rod 4. At this time, the fixing rod 2 8 will enter the inside of the fixing groove 2 11, and the fixing rod 2 8 can be fixed by the clamping plate 9. At this time, the transmission rod body 6 and the connecting rod 2 will form a whole. When in use, the support plate 14 and the limit rod 4 can limit the connection position of the transmission rod body 6 and the connecting rod 2, and can prevent the connecting rod 2 and the transmission rod body 6 from staggered and deflected.
