Description

Technical Field

[0001] This application relates to the field of catheter flaring and docking technology, specifically to a quick docking device for catheter flaring. Background Technology

[0002] In the field of catheter manufacturing, flaring is a critical process whose quality directly affects the subsequent connection and performance of the catheter. However, existing catheter flaring and mating devices have several problems that urgently need to be addressed. On the one hand, catheter mating accuracy is difficult to guarantee. Traditional devices lack effective positioning mechanisms, leading to inaccurate alignment between the pressure head and the catheter during the flaring process, resulting in significant deviations in flaring dimensions, affecting product quality, increasing the defect rate, and raising production costs. On the other hand, the clamping components, as the parts that directly contact the catheter, are prone to wear and tear after frequent use. Traditional devices often lack a structure designed for easy replacement of these clamping components. Once damaged, the replacement process is complex and time-consuming, increasing equipment downtime and impacting production efficiency. Furthermore, the automation and coordination between the various components of the device are insufficient, making it impossible to achieve precise coordination of each action, resulting in low efficiency throughout the flaring operation and making it difficult to meet the needs of large-scale production.

[0003] Therefore, developing a rapid docking device for catheter flaring that can solve the above problems is of great significance for improving catheter flaring quality and production efficiency. Summary of the Invention

[0004] To address the aforementioned technical problems, this application solves the issues of low catheter docking accuracy during catheter flaring, inconvenient replacement of clamping components after wear, and insufficient automation and coordination of the device in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a quick-connection device for catheter flaring, comprising a support base, a vertical support plate fixedly mounted on the support base, a horizontal support plate fixedly mounted on the vertical support plate, a main shaft rotatably mounted on the horizontal support plate, a sprocket fixedly mounted on the main shaft, a chain mounted on the sprocket, the sprocket and the chain meshing, and multiple clamping rods mounted on the chain. Two side sliding rods are slidably mounted on the horizontal support plate, and a limit rod is fixedly mounted on both side sliding rods. The limit rod is L-shaped, a buffer plate is fixedly mounted on the support base, and a limit block is fixedly mounted on the buffer plate. The groove of the limit block matches the end of the limit rod near the support base.

[0006] Preferably, the chain is provided with multiple sliding grooves, on which a mounting rod is slidably mounted, and on which a clamping rod is slidably mounted. The mounting rod is provided with a shaft, and a mounting spring is sleeved on the shaft. The two ends of the mounting spring are fixedly connected to the mounting rod and the clamping rod, respectively.

[0007] Preferably, a horizontal plate is fixedly installed on the two side slide rods, and a return spring is sleeved on each of the two side slide rods. The two ends of the return spring are fixedly connected to the horizontal plate and the supporting horizontal plate, respectively.

[0008] Preferably, a bracket is fixedly mounted on the support base, a cylinder is fixedly mounted on the bracket, a pressure head and a support plate are fixedly mounted on the output end of the cylinder, a plurality of sliders are slidably mounted on the support plate, and a connecting rod is provided at the end of the slider away from the support base, the connecting rod being used to connect two adjacent sliders.

[0009] Preferably, an upper belt is provided at one end of the main shaft near the slider, and the two main shafts on the same side are connected by the upper belt.

[0010] Preferably, the end of the main shaft away from the slider is provided with an inner belt, which connects the two main shafts on opposite sides. A direction converter is provided on the main shaft on the opposite side to change the direction of rotation of the main shaft.

[0011] The technical solution provided in this application has the following advantages compared with the prior art:

[0012] 1. This application achieves precise catheter docking through an ingenious limiting design. After the catheter is moved to the appropriate position by the clamping rod, the limiting rod and the limiting block cooperate with each other. The limiting rod moves downward and inserts into the groove of the limiting block, thus precisely limiting the translation of the limiting rod and preventing the clamping rod from moving further. This process achieves precise fixation of the catheter position, allowing the pressure head to be quickly and accurately aligned with the catheter. In actual production, this precise docking greatly improves the flaring quality, ensuring high consistency in flaring size and shape, effectively reducing the defect rate caused by inaccurate docking, and improving the overall product quality. At the same time, after the limiting rod is fixed, it can continuously prevent the movement of the chain and clamping rod, ensuring that each delivered catheter remains in the same position, achieving precise positioning and rapid docking of the catheter. This not only improves production efficiency but also ensures the stability of the production process, providing a strong guarantee for large-scale, high-quality catheter flaring production.

[0013] 2. This application fully considers ease of maintenance in its design. The mounting rod can slide flexibly on the chain's groove and is connected to the clamping rod via a mounting spring. This structural design enables quick assembly and disassembly of the clamping rod. In actual production, the clamping rod needs to frequently come into hard contact with the conduit, resulting in rapid wear. When the clamping rod wears down, reducing its clamping capacity and affecting normal transport and docking, operators can easily manually control the clamping rod to slide on the mounting rod, stretching the mounting spring to disengage the clamping rod from the chain, thus quickly replacing it with a new clamping rod and mounting rod. This rapid replacement method greatly reduces maintenance difficulty, significantly reduces downtime due to component damage, and improves equipment operating efficiency. Furthermore, this device allows for easy replacement of clamping rods of different specifications according to the conduit diameter. This feature enhances the device's adaptability to various conduit specifications, eliminating the need for companies to equip multiple sets of equipment for different diameter conduits, effectively reducing equipment procurement costs and improving the equipment's versatility and practicality.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] like Figures 1 to 5 As shown, a quick docking device for catheter flaring includes a support base 101, a support vertical plate 102 fixedly mounted on the support base 101, a support horizontal plate 103 fixedly mounted on the support vertical plate 102, a main shaft 119 rotatably mounted on the support horizontal plate 103, a sprocket 104 fixedly mounted on the main shaft 119, a chain 105 mounted on the sprocket 104, the sprocket 104 meshing with the chain 105, and a plurality of clamping rods 106 mounted on the chain 105.

[0023] Two side slide rods 109 are slidably arranged on the support plate 103. A limit rod 112 is fixedly arranged on both side slide rods 109. The limit rod 112 is L-shaped. A buffer plate 124 is fixedly arranged on the support base 101. A limit block 113 is fixedly arranged on the buffer plate 124. The groove of the limit block 113 matches the end of the limit rod 112 near the support base 101.

[0024] Specifically, each side is provided with a vertical support plate 102 and a horizontal support plate 103. Two main shafts 119 and sprockets 104 are provided on one horizontal support plate 103. A chain 105 is supported and driven by two brackets 114. Eight clamping rods 106 are provided on one chain 105. The clamping rods 106 follow the movement and rotation of the chain 105, thereby clamping and releasing the conduit and driving the conduit to move to the flaring working area.

[0025] Once the catheter has moved to the appropriate position, the limiting rod 112 is moved downwards, towards the support base 101. This causes the limiting rod 112 to push the two side sliding rods 109 downwards on the support plate 103, and compresses the return spring 111 on the side sliding rods 109 via the plate 110. The return spring 111 is used for subsequent repositioning after flaring. When the limiting rod 112 moves downwards, its lower end inserts into the groove of the limiting block 113, thereby restricting the lower end of the limiting rod 112 through the limiting block 113. This, combined with the fixed connection between the upper end of the limiting rod 112 and the side sliding rods 109, restricts the translation of the limiting rod 112, i.e., its movement along the direction of movement of the clamping rod 106. After the limiting rod 112 is inserted into the limiting block 113, the limiting rod 112 covers the movement path of the clamping rod 106, so that the clamping rod 106 approaches and contacts the limiting rod 112. The limiting rod 112 blocks the movement of the clamping rod 106, preventing the clamping rod 106 from moving excessively, thus achieving precise fixation of the catheter position. In this way, the pressure head 116 and the catheter can be quickly and accurately aligned, ensuring the quality of the flaring.

[0026] like Figures 2 to 5 As shown, the chain 105 is provided with multiple sliding grooves, on which an installation rod 107 is slidably disposed. A clamping rod 106 is slidably disposed on the installation rod 107. A shaft is provided on the installation rod 107, and an installation spring 108 is sleeved on the shaft. The two ends of the installation spring 108 are fixedly connected to the installation rod 107 and the clamping rod 106, respectively.

[0027] Specifically, the mounting rod 107 and the clamping rod 106 can be quickly assembled and disassembled by sliding the mounting rod 107 on the groove on the chain 105. When clamping the conduit, the wear and tear of the clamping rod 106, which requires frequent hard contact, increases rapidly due to prolonged operation. After long-term use, the clamping rod 106's clamping ability on the conduit will decrease, affecting normal conveying and docking. This quick assembly and disassembly makes it convenient for staff to replace the damaged clamping rod 106.

[0028] The clamping rod 106 includes a horizontal bar and an arc-shaped bar. The horizontal bar is used to install onto the mounting rod 107, and the arc-shaped bar is used to clamp the conduit and mates with the outer wall of the conduit. Different specifications of clamping rods 106 can be replaced according to the diameter of the conduit. When the horizontal bar of the clamping rod 106 is installed, the end away from the arc-shaped bar will extend beyond the inner wall of the chain 105, that is, both ends of the horizontal bar are located on the inner and outer sides of the chain 105, so that the subsequent limiting rod 112 can block the horizontal bar of the clamping rod 106 on the inner side of the chain 105, thereby blocking the entire clamping rod 106. The mounting rod 107 includes a main rod, on which one long rod, one short rod, and one shaft are fixedly installed. The short rod is inserted into the groove of the chain 105 to install the mounting rod 107 onto the chain 105. The long rod restricts the sliding of the clamping rod 106. The shaft and the elastic force of the mounting spring 108 give the clamping rod 106 a force close to the main rod of the mounting rod 107.

[0029] In use, when replacing the mounting rod 107 and clamping rod 106 onto the chain 105, manually control the clamping rod 106 to slide downwards on the long rod and shaft of the mounting rod 107, and stretch the mounting spring 108 on the shaft of the mounting rod 107. This causes the clamping rod 106 to slide a distance away from the main rod of the mounting rod 107 on the long rod. This distance needs to be greater than the thickness of the chain 105, but the long rod of the mounting rod 107 must be long enough so that the clamping rod 106 will not detach from the mounting rod 107. Then, control the main rod of the mounting rod 107 to move upwards, so that the short rod of the mounting rod 107 slides on the groove of the chain 105 and detaches from the chain 105. Thus, the mounting rod 107 and clamping rod 106 can be detached from the chain 105, achieving quick disassembly and assembly of the mounting rod 107 and clamping rod 106. New mounting rods 107 and clamping rods 106 can then be directly replaced onto the chain 105.

[0030] like Figure 4 and Figure 5 As shown, a horizontal plate 110 is fixedly installed on the two side slide rods 109, and a return spring 111 is sleeved on each of the two side slide rods 109. The two ends of the return spring 111 are fixedly connected to the horizontal plate 110 and the supporting horizontal plate 103, respectively.

[0031] Specifically, the side sliding rod 109 passes through the supporting horizontal plate 103 and is located on both sides of the supporting vertical plate 102 to prevent interference between the side sliding rod 109 and the supporting vertical plate 102 when the side sliding rod 109 slides. The L-shaped structure of the limiting rod 112 includes a horizontal rod and a vertical rod. The horizontal rod is fixedly connected to the two side sliding rods 109, and the vertical rod is used to insert into the groove of the limiting block 113.

[0032] like Figure 1As shown, a bracket 114 is fixedly installed on the support base 101, and a cylinder 115 is fixedly installed on the bracket 114. A pressure head 116 and a support plate 117 are fixedly installed on the output end of the cylinder 115. A plurality of sliders 118 are slidably installed on the support plate 117. A connecting rod is provided at the end of the slider 118 away from the support base 101. The connecting rod is used to connect two adjacent sliders 118.

[0033] Specifically, during the flaring of the conduit, the output end of the cylinder 115 controls the pressure head 116 and the support plate 117 to move downwards, i.e., towards the support base 101. This causes the slider 118 on the support plate 117 to approach and contact a limiting rod 112, thus pushing the limiting rod 112 downwards. The limiting rod 112 pushes the side slide rod 109 downwards on the support horizontal plate 103, compressing the return spring 111 via the horizontal plate 110. After the vertical rod of the limiting rod 112 inserts into the groove of the limiting block 113, the limiting rod 112 cannot continue to move downwards, thus blocking the slider 118 from moving further. Consequently, the support plate 117 continues to move downwards, causing the slider 118 to slide on the groove on the support plate 117. That is, the slider 118 and the limiting rod 112 remain stationary, while the support plate 117 and the pressure head 116 continue to move towards the support base 101. This allows the pressure head 116 to be inserted into the flared conduit for flaring.

[0034] After the limiting rod 112 is fixed, the chain 105 continues to move, driving the mounting rod 107 and the clamping rod 106 to move. When the clamping rod 106 contacts the vertical bar of the limiting rod 112, the vertical bar of the limiting rod 112 blocks the clamping rod 106, thereby blocking the movement of the mounting rod 107 and the chain 105, thus maintaining the position of the conduit conveyed by the clamping rod 106, so that the conduit is in the same position each time it is conveyed, achieving precise positioning and rapid docking of the conduit.

[0035] After the pressure head 116 expands the conduit, the cylinder 115 controls the pressure head 116 to return to its original position. During this process, the position of the conduit is fixed by the clamping rods 106 on both sides, so that the pressure head 116 is disengaged from the conduit. When the pressure head 116 is completely disengaged from the conduit and moves a distance, the support plate 117 contacts the connecting rod on the slider 118, thereby lifting the slider 118 upward. This causes the slider 118 to move upward, and the limiting rod 112 can be gradually reset by the elastic force of the horizontal plate 110. That is, following the movement of the slider 118, the lower end of the vertical rod of the limiting rod 112 moves to the upper end of the chain 105. Then, the chain 105 is controlled to move, and the conduit is moved by the mounting rod 107 and the clamping rod 106, thus switching between the conduit to be processed and the processed conduit.

[0036] like Figure 2As shown, an upper belt 123 is provided at one end of the main shaft 119 near the slider 118, and the two main shafts 119 on the same side are connected by the upper belt 123.

[0037] like Figure 3 As shown, an inner belt 120 is provided at the end of the main shaft 119 away from the slider 118, and the two main shafts 119 on the opposite side are connected by the inner belt 120. A direction converter is provided on the main shaft 119 on the opposite side to change the direction of rotation of the main shaft 119.

[0038] Specifically, the reversing device causes the main shaft 119 on one side to form an inner and outer shaft, transmitting power through gears. However, the inner and outer shafts rotate in opposite directions, i.e., coaxial but opposite-direction rotation. The main shaft 119 on the same side transmits power through the upper belt 123, while the main shaft 119 on the opposite side transmits power through the inner belt 120, and then through the external motor 122 and the outer belt 121. In use, when the motor 122 is started, its output drives one main shaft 119 to rotate through the outer belt 121. The main shaft 119 drives the other three main shafts 119 to rotate through the inner belt 120 and the upper belt 123, and together with the reversing device, the chains 105 on both sides move in the same direction to clamp, transport, and release the guide tube.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
