Description

Technical Field

[0001] The utility model relates to a connector, in particular to a quick sealing connector for testing an explosion-proof valve. Background Art

[0002] Explosion-proof valves need to be tested during the production process. Explosion-proof valves are generally large and have different shapes, but they all have one common feature, that is, they all have a bayonet and a very narrow plane.

[0003] The traditional way to test explosion-proof valves is to manually connect the connector and the fixings to the explosion-proof valve. After the connector and the explosion-proof valve are connected, air is injected into the connector to detect whether the explosion-proof valve meets the explosion-proof standards.

[0004] As labor costs are getting more and more expensive, battery PACK packages are relatively large, and manual operation of connecting connectors to explosion-proof valves is cumbersome, time-consuming, and labor-intensive, and testing efficiency is low. In order to increase production, multiple manual testing stations are required for testing, which increases enterprise costs. Utility Model Content

[0043] Embodiment 1: The specific structure of the utility model is as follows:

[0044] Please refer to the attached Figure 1-9 The utility model discloses a quick sealing connector for testing an explosion-proof valve, comprising:

[0049] The first step 44 is provided with a column hole 41, and the column hole 41 is placed with a compression spring 19;

[0050] The main body shell 4 is further provided with two side holes 43 , which are coaxial and communicate with the piston cavity 42 , and the two coaxial side holes 43 and the two column holes 41 are distributed in a cross shape.

[0051] A preferred technical solution of this embodiment: the piston group includes:

[0052] The front piston 7 has a first end inserted into the piston cavity 42, and a second end thereof forms a limiting structure with the second step, such as Figure 4 As shown, the length of the front piston 7 inserted into the piston chamber 42 is greater than the distance between the first step and the second step. Figure 4 In the middle, the position of the compression spring 19, there is a gap between the first step 44 and the piston 8, and this gap allows the piston 8 to move Figure 4 The upward movement;

[0053] The piston 8 is connected to the first end of the front piston 7 by screws and forms a limiting structure with the first step. A compression spring 19 is provided in the column hole 41. One end of the compression spring 19 abuts against the piston 8, and the other end abuts against the bottom surface of the column hole 41.

[0054] like Figure 4 As shown, the front piston 7 has an annular groove at the connection between it and the piston 8, and an "O" ring 1 is installed in the annular groove to prevent air leakage between the front piston 7 and the piston 8.

[0055] like Figure 4 As shown, a ring groove is provided on the circumferential side of the piston 8, and a sealing ring 2 is embedded in the ring groove. The sealing ring 2 forms a sealing structure between the piston 8 and the inner wall of the main body shell 4.

[0056] A preferred technical solution of this embodiment: the piston group also includes a pressure plate 12 and a main sealing ring 14. The outer edge of the pressure plate 12 is covered with the main sealing ring 14 and fixed to the second end of the front piston 7. The main sealing ring 14 forms a sealing structure between the pressure plate 12 and the inner wall of the piston cavity 42. The pressure plate 12 is a circular plate structure, which is fixed to the second end of the main shell 4 by screws. After the pressure plate 12 is fixed, the main sealing ring 14 is pressed. The main sealing ring 14 is a circular ring, one end of which is chamfered to form a cone and abuts against the inner wall of the piston cavity 42, and the other end forms an inner step and is pressed by the pressure plate 12.

[0057] A preferred technical solution of this embodiment: the first end cover of the main shell 4 is connected to a bottom plate 9, a sealing structure is formed between the bottom plate 9 and the inner wall of the piston chamber 42, and a charging and discharging hole 91 is provided on the bottom plate 9 to connect the piston chamber 42 with the external air, the inner surface of the bottom plate 9 is opposite to the piston 8, and the bottom plate 9 has a circular boss that cooperates with the main shell 4, the circumferential side of the circular boss is provided with an annular groove, and a sealing ring 2 is embedded in the annular groove of the circular boss.

[0058] A pressure chamber is formed between the bottom plate 9 and the piston 8. When the charging and discharging holes 91 are connected to the driving air source, air enters the pressure chamber, the pressure increases, and the piston 8 is forced to move Figure 4 The upward movement.

[0059] At least two protective covers 10 are installed at the second end edge of the main body shell 4. The protective covers 10 are used to protect the interface of the explosion-proof valve to avoid scratching the explosion-proof valve. The inner side surface of the protective cover 10 is an arc surface, and the arc surface of the inner side surface is the same arc as the circular hole of the main body shell 4. The two protective covers 10 are arranged facing each other and the installation direction of one protective cover 10 is the direction of the other protective cover 10 after rotating 180 degrees.

[0060] A preferred technical solution of this embodiment: the front piston 7 has a side channel 74 that runs through both sides, and two groups of coaxial arc holes 72 that communicate with the side channel 74 at the same height. The two groups of coaxial arc holes 72 are arranged orthogonally to the side channel 74 and the two groups of coaxial arc holes 72 are arranged at the same height. Figure 8 As shown, the outer arc sides of the two groups of arc-shaped shaft holes 72 face each other, and the inner arc sides face away from each other. When the clamping mechanism 5 is driven by the piston group, the clamping mechanism 5 performs a closing action. The second end of the front piston 7 has a circular groove 71, and the pressure plate 12 is installed in the circular groove 71.

[0061] A preferred technical solution of this embodiment: Figure 6-7 As shown, the clamping mechanism 5 comprises:

[0062] Two sliders 51, one end of each slider 51 enters the side channel 74, and is lifted and lowered along the two groups of coaxial arc holes 72 through the side hinge assembly. The outer ends of the two sliders 51 extend out of two side holes 43 respectively, and the side holes 43 are square holes. The slider 51 is a square slider. Pin holes 511 are provided on both sides of the slider 51. The pin holes 511 on both sides are installed with hinge pins 54 with shaft sleeves 55. The hinge pins 54 are in the coaxial arc holes 72. Therefore, the slider 51 is limited in its range of motion by the coaxial arc holes 72.

[0063] At least two cylindrical pins 53 are provided, one end of which is fixed to one of the sliders 51 and the other end of which is passed through the guide hole of the other slider 51 to realize the relative movement of the two sliders 51. The cylindrical pin 53 has a guiding function and also has a function of preventing the slider 51 from deflecting.

[0064] Two clamping plates 52 are respectively fixed to the outer ends of the two sliders 51. One end of the clamping plate 52 has a hook portion, and the hook portion extends toward the second end of the main body shell 4 and is higher than the second end of the main body shell 4 by a certain distance. The inner end of the hook portion of the clamping plate 52 is provided with an arc-shaped clamping surface, and the arc-shaped clamping surface is the same arc as the circular opening of the main body shell.

[0065] A preferred technical solution of this embodiment is that the outer arcs of the two groups of coaxial arc holes 72 are opposite and the distance between the highest point of the coaxial arc holes 72 and the lowest point of the coaxial arc holes 72 is sufficient for the two clamping plates 52 to open and close.

[0066] The lower section of the coaxial arc hole 72 is a straight linear hole. The purpose of designing the linear hole is to prevent the main sealing ring 14 from being pushed into place after the clamping mechanism 5 is clamped, that is, after the clamping mechanism 5 is clamped, the main sealing ring 14 can still move forward a certain distance.

[0067] like Figure 6 , 8 As shown, a recessed groove 73 is provided at the outer hole of the coaxial arc hole 72 .

[0068] Embodiment 2:

[0069] The following is the operating principle of the utility model explosion-proof valve test quick seal connector:

[0070] 1. The initial state of the connector, such as Figure 3-4 , Figure 6 As shown, the charging and discharging holes 91 are connected to the driving air source. Initially, the driving air source is not powered on. The two compression springs 19 open the piston 8 and the first step, so that the hinge pin 54 of the clamping mechanism 5 is at the highest point of the coaxial arc hole 72. At this time, the two clamps 52 are in an open state.

[0071] 2. During the test, the manipulator grasps the connector of the utility model and moves to the top of the explosion-proof valve.

[0072] 3. Use a manipulator to align the connector of the utility model with the test end of the explosion-proof valve and insert it. At this time, the protective cover 10 has the function of repositioning and preventing the explosion-proof valve from being damaged.

[0073] 4. After the connector of the present invention is inserted to the bottom, the protective cover 10 is flush with the explosion-proof valve, and the clamping plate 52 is just in the middle of the slot of the explosion-proof valve.

[0074] 5. Start the driving air source and slowly inflate the air charging and discharging port 91. The purpose of slow inflation is to prevent the piston group from violent movement. After the air is taken in by the air charging and discharging port 91, the pressure in the air pressure chamber increases, and the piston 8 drives the front piston 7 to move upward. At the same time, the piston 8 further squeezes the compression spring 19.

[0075] 6. Since the clamping mechanism 5 is immobilized by the side hole 43, after the front piston 7 rises, the coaxial arc hole 72 also rises. Since the low points of the coaxial arc hole 72 are close to each other, it will drive the hinge pin 54 to move laterally while rising, thereby making the two sliders 51 move toward each other. When the two sliders 51 move toward each other, they will drive the two clamping plates 52 to move toward each other, and the hooks of the two clamping plates 52 are clamped in the card slots of the explosion-proof valve.

[0076] 7. During the design, when the coaxial arc hole 72 has not completely risen, the two clamping plates 52 have already clamped the slot, and the piston group continues to rise, so that the detection end of the explosion-proof valve is in close contact with the pressure plate 12 and the main sealing ring 14 to achieve sealing. After the sealing is completed, the driving air source maintains the air pressure, and the manipulator releases the connector to perform the next step of the operation.

[0077] 8. After a period of testing, when the explosion-proof valve test is completed, the manipulator grabs the connector of the utility model, and then closes the driving air source. The piston group is reset under the action of the compression spring 19, the splint 52 is opened, and the manipulator removes the connector of the utility model to perform the next step of the operation.

[0078] In summary, the quick-seal connector for testing explosion-proof valves of the utility model is delivered to the explosion-proof valve by a manipulator, and then the piston group and the clamping mechanism of the connector work together to automatically fasten and connect the explosion-proof valve and the connector, so as to achieve the purpose of rapid testing and improve the testing efficiency. The quick-seal connector for testing explosion-proof valves of the utility model is provided with a protective cover, which plays a role in positioning and preventing the explosion-proof valve from being scratched. The quick-seal connector for testing explosion-proof valves of the utility model cleverly uses the piston group to drive the clamping mechanism, so that the splint performs the action of opening and clamping. The quick-seal connector for testing explosion-proof valves of the utility model is provided with a reset structure, and the reset structure is that when the air source is closed, the compression spring resets the main shell and the piston group.

[0079] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
