Description

Technical Field

[0001] This utility model belongs to the field of manual tool technology, specifically a sterile connector clamp. Background Technology

[0002] In existing reactor reactions in the upstream pharmaceutical industry, it is necessary to measure pH electrode data inside the reactor. Sterile connectors use male and female heads that mate. To ensure a sterile environment inside the reactor, the pH or conductivity electrodes must be sterilized before use. The sterilized electrodes are then inserted through disposable sterile connectors. The sterile connectors engage via ratchet teeth. However, when installing the male connector, the operator's pressing pressure is limited, resulting in poor installation and insufficient electrode insertion depth.

[0003] Reference CN104552070A discloses a clamping-type medical clamp, including a main body and a left clamping block fixed to the lower end of the main body; the main body has a horizontally arranged sliding groove, a slider is arranged in the sliding groove, and a right clamping block is fixed to the lower end of the slider; the slider has a horizontally arranged slider groove, which is open on the right side and has a slit on the upper side; a spring is arranged in the slider groove; a stop block is provided at the right end of the spring, which passes through the slit and is fixed to the main body; an adjusting rod is threaded onto the slider, the right end of the adjusting rod has a pressure block, and the left end of the adjusting rod has a handle, the pressure block is located in the slider groove and connected to the left end of the spring. It is used to clamp objects of different sizes, but the assembly of sterile connector male and female heads is poor. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a sterile connector clamp that can be assembled relatively easily and ensures sufficient electrode insertion depth.

[0005] To solve the above technical problems, this utility model provides a sterile connector clamp, including a fixed base, a clamping groove I provided on the clamping plate at the front end of the fixed base, a guide shaft spring device provided in the guide cavity in the middle of the fixed base, a slider installed on the guide shaft spring device, a clamping groove II installed on the slider, the clamping groove II and a handle connected, and the handle installed in the handle cavity at the rear end of the fixed base through a pin.

[0006] By adopting the above technical solution, the clamp slots I and II on the fixture, together with the guide shaft spring device and the slider structure, through the reasonable structure to assist the operation, transform the complex operation that originally relied on the operator to manually and accurately control the pressing pressure and insertion depth into the mechanical structure of the fixture, which greatly reduces the difficulty of operation. Even if the operator is not experienced, he can complete the assembly relatively easily and ensure that the electrode insertion depth is sufficient.

[0007] Preferably, the guide shaft spring device includes a guide shaft, on which a spring and a slider are mounted, the slider being close to the handle and sliding within the guide cavity.

[0008] By adopting the above technical solution, the guide shaft and guide cavity cooperate with each other to define a clear boundary and range for the movement of the slider, preventing unnecessary displacement of the slider in the horizontal or vertical direction. A spring is fitted onto the guide shaft to provide elastic restoring force to the slider.

[0009] Preferably, a screw hole is provided on the inner side wall of the guide cavity, and an adjustable bolt is provided in the screw hole, with the head of the adjustable bolt abutting against one side of the slider.

[0010] By adopting the above technical solution, the displacement distance can be adjusted by bolts, which can also serve as a limit to ensure that the sterile connector is not over-pressured and to prevent the sterile connector from being subjected to excessive compressive force and breaking.

[0011] Preferably, there are two guide shafts; the guide shafts pass through the guide holes on the slider and are installed in the shaft holes on the inner side wall of the guide cavity.

[0012] By adopting the above technical solution, the two guide shafts together constrain the slider, which can more effectively prevent the slider from deflecting during movement compared to a single guide shaft.

[0013] Preferably, an end cap is provided on the top surface of the guide cavity, and an edge is provided on the bottom edge of the guide cavity, with the edge supporting the slider.

[0014] By adopting the above technical solution and using end caps for dust prevention, jamming caused by external factors can be avoided.

[0015] Preferably, a grip bar is installed on the handle cavity.

[0016] By adopting the above technical solution, the combination of the handle and grip makes the pressing operation of the handle more stable.

[0017] Preferably, a push plate is provided at the bottom of the handle, and a connecting rod is installed on the support leg of the clamp slot II, with the push plate and the connecting rod being rotatably connected.

[0018] By adopting the above technical solution, the handle, push plate, and connecting rod constitute a lever-like transmission system. By pressing the handle, the connecting rod pushes the slider forward, thereby displacing the slider and compressing the mating distance between the male and female connectors of the sterile connector. This achieves a large output force with a small operating force, thus reducing the operator's workload and making the assembly of the male and female connectors more effortless.

[0019] Preferably, the bottom of the handle is provided with an arc-shaped push part, which is in contact with the slider.

[0020] By adopting the above technical solution, when the operator presses the handle, the pushing part can smoothly transmit the force to the slider, pushing the slider to move forward in a straight line along the guide shaft, thereby realizing the displacement of the slider.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The clamp slots I and II on the fixture of this utility model, together with the guide shaft spring device and the slider structure, through the reasonable structure to assist operation, transform the complex operation that originally relied on the operator to manually and accurately control the pressing pressure and insertion depth into the mechanical structure of the fixture, which greatly reduces the difficulty of operation. Even if the operator is not experienced, he can complete the assembly relatively easily and ensure that the electrode insertion depth is sufficient.

[0022] 2. The guide shaft and guide cavity of this utility model cooperate with each other to define a clear boundary and range for the movement of the slider, and prevent the slider from undergoing unnecessary displacement in the horizontal or vertical direction.

[0023] 3. In this utility model, the spring is mounted on the guide shaft to provide elastic restoring force for the slider. During operation, when the handle drives the slider to compress the spring and move forward to complete the assembly of the male and female heads, releasing the handle will cause the spring's elastic force to automatically return the slider to its initial position, reducing the workload and time required for manual slider reset and improving operational efficiency.

[0026] like Figure 1-3As shown, the sterile connector clamp includes a fixed base 1. A clamping groove I7 is provided on the clamping plate at the front end of the fixed base 1. The clamping groove I7 mates with the female end of the sterile connector for fixation. A guide shaft spring device 3 is provided in the guide cavity 2 in the middle of the fixed base 1. To save manpower, after the work is completed, it can provide partial spring force, allowing the slider 4 to automatically return to its original position, eliminating the need for resetting before the next use. The slider 4 is mounted on the guide shaft spring device 3, and a clamping groove II8 is provided on the slider 4. The clamping groove II8 mates with the male end of the sterile connector. The clamping groove II8 is connected to a handle 6, which is mounted in the handle cavity 10 at the rear of the fixed base 1 via a pin 9. The clamping grooves I7 and II8, together with the guide shaft spring device 3 and the slider 4, provide a reasonable structural assistance to the operation. This transforms the complex operation, which originally relied on the operator to manually and precisely control the pressing pressure and insertion depth, into a mechanical operation using the clamp, greatly reducing the difficulty of operation. Even inexperienced operators can easily complete the assembly and ensure sufficient electrode insertion depth.

[0027] The guide shaft spring device 3 includes a guide shaft 11, on which a spring 12 and a slider 4 are mounted. The slider 4 is close to the handle 6 and slides within the guide cavity 2. The guide shaft 11 and the guide cavity 2 cooperate to define a clear boundary and range for the movement of the slider 4, preventing unnecessary displacement of the slider 4 in the horizontal or vertical direction. The spring 12, mounted on the guide shaft 11, provides elastic restoring force to the slider 4. During operation, when the handle 6 moves the slider 4 forward, compressing the spring 12 to complete the male and female head assembly, releasing the handle 6 causes the elastic force of the spring 12 to automatically return the slider 4 to its initial position, reducing the workload and time required for manual repositioning of the slider 4 and improving operational efficiency.

[0028] A screw hole is provided on the inner wall of the guide cavity 2, and an adjustable bolt (not shown in the figure) is installed in the screw hole. The head of the adjustable bolt abuts against one side of the slider 4. The displacement distance is adjusted by the bolt, which also acts as a limit to ensure that the sterile connector is not over-pressurized, thus preventing the sterile connector from being broken due to excessive compressive force. After tightening, the handle 6 is released by hand, and the slider 4 automatically rebounds due to the compression of the spring 12 on the guide shaft 11.

[0029] There are two guide shafts 11; the guide shafts 11 pass through the guide holes 13 on the slider 4 and are installed in the shaft holes on the inner side wall of the guide cavity 2. The two guide shafts 11 together constrain the slider 4, which can more effectively prevent the slider 4 from deflecting during the movement compared to a single guide shaft 11.

[0030] An end cap 14 is provided on the top surface of the guide cavity 2, and an edge is provided on the bottom edge of the guide cavity 2, which supports the slider 4. The end cap 14 is dustproof and prevents jamming caused by external factors.

[0031] A grip 17 is mounted on the handle cavity 10. The handle 6 and the grip 17 work together to make the pressing operation of the handle 6 more stable.

[0032] A push plate 15 is installed at the bottom of the handle 6, and a connecting rod 5 is installed on the support leg of the clamp slot II 8. The support leg and the connecting rod 5 are connected by bolts. The connecting rod 5 pushes the support leg forward, thereby displacing the slider 4. The push plate 15 and the connecting rod 5 are rotatably connected by a pin. The handle 6, the push plate 15, and the connecting rod 5 constitute a lever-like transmission system. By pressing the handle 6, the connecting rod 5 pushes the slider 4 forward, thereby displacing the slider 4 and compressing the mating distance between the male and female heads of the sterile connector. A large output force is achieved with a small operating force, thereby reducing the labor intensity of the operator and making the assembly operation of the male and female heads more effortless. Example 2

[0033] like Figure 4-6 As shown, the sterile connector clamp includes a fixed base 1. A clamping groove I7 is provided on the clamping plate at the front end of the fixed base 1. The clamping groove I7 mates with the female end of the sterile connector to provide fixation. A guide shaft spring device 3 is provided in the guide cavity 2 in the middle of the fixed base 1. To save manpower, after the work is completed, it can provide part of the spring force to allow the slider 4 to automatically return to its original position, so that it does not need to be reset for the next use. The slider 4 is installed on the guide shaft spring device 3, and the clamping groove II8 is installed on the slider 4. The clamping groove II8 mates with the male end of the sterile connector. The clamping groove II8 is connected to the handle 6, and the handle 6 is installed in the handle cavity 10 at the rear of the fixed base 1 via a pin 9. The clamping groove I7 and clamping groove II8 of this application, together with the guide shaft spring device 3 and the slider 4, through a reasonable structure to assist operation, transform the complex operation that originally relied on the operator to manually and accurately control the pressing pressure and insertion depth into the mechanical structure of the clamp, which greatly reduces the difficulty of operation. Even if the operator is not experienced, he can complete the assembly relatively easily and ensure that the electrode insertion depth is sufficient.

[0034] The guide shaft spring device 3 includes a guide shaft 11, on which a spring 12 and a slider 4 are mounted. The slider 4 is close to the handle 6 and slides within the guide cavity 2. The guide shaft 11 and the guide cavity 2 cooperate to define a clear boundary and range for the movement of the slider 4, preventing unnecessary displacement of the slider 4 in the horizontal or vertical direction. The spring 12, mounted on the guide shaft 11, provides elastic restoring force to the slider 4. During operation, when the handle 6 moves the slider 4 forward, compressing the spring 12 to complete the male and female head assembly, releasing the handle 6 causes the elastic force of the spring 12 to automatically return the slider 4 to its initial position, reducing the workload and time required for manual repositioning of the slider 4 and improving operational efficiency.

[0035] A screw hole is provided on the inner wall of the guide cavity 2, and an adjustable bolt (not shown in the figure) is installed in the screw hole. The head of the adjustable bolt abuts against one side of the slider 4. The displacement distance is adjusted by the bolt, which also acts as a limit to ensure that the sterile connector is not over-pressurized, thus preventing the sterile connector from being broken due to excessive compressive force. After tightening, the handle 6 is released by hand, and the slider 4 automatically rebounds due to the compression of the spring 12 on the guide shaft 11.

[0036] There are two guide shafts 11; the guide shafts 11 pass through the guide holes 13 on the slider 4 and are installed in the shaft holes on the inner side wall of the guide cavity 2. The two guide shafts 11 together constrain the slider 4, which can more effectively prevent the slider 4 from deflecting during the movement compared to a single guide shaft 11.

[0037] An end cap 14 is provided on the top surface of the guide cavity 2, and an edge is provided on the bottom edge of the guide cavity 2, which supports the slider 4. The end cap 14 is dustproof and prevents jamming caused by external factors.

[0038] A grip 17 is mounted on the handle cavity 10. The handle 6 and the grip 17 work together to make the pressing operation of the handle 6 more stable.

[0039] The bottom of the handle 6 is provided with an arc-shaped pushing part 16, which is in contact with the slider 4. The arc-shaped pushing part 16 makes the operation of pushing the slider 4 smoother. When the operator presses the handle 6, the pushing part 16 can smoothly transmit the force to the slider 4, pushing the slider 4 to move forward in a straight line along the guide shaft 11, realizing the displacement of the slider 4 and compressing the mating distance between the male and female heads of the sterile connector.
