Description

Technical Field

[0001] This utility model relates to the field of sanitary clamp technology, specifically to a sanitary clamp connector. Background Technology

[0002] Sanitary clamp fittings are pipe connection components used in industries with extremely high hygiene requirements, such as food, medicine, cosmetics, dairy products, and bioengineering. They feature quick installation, easy disassembly, thorough cleaning, and strong sealing.

[0003] Sanitary clamp fittings achieve a seal by mechanically compressing the sealing ring. The clamp is fitted over the outside of the flange, causing the sealing ring to be compressed and fill the flange gap. During installation, the upper and lower clamps are usually connected by bolts to achieve locking. This connection method is inefficient and severely affects installation in confined spaces. Utility Model Content

[0004] To solve the above problems, this utility model proposes a sanitary clamp connector, the specific technical solution of which is as follows:

[0005] A sanitary clamp connector includes an upper clamp and a lower clamp. One end of the upper clamp is rotatably connected to the lower clamp. A first boss is provided at the non-rotating end of the upper clamp, and a second boss is provided at the non-rotating end of the lower clamp. A locking assembly is provided between the first and second bosses. The second boss has an upward-opening cavity. The locking assembly includes a clamping block, a positioning block, and a telescopic rod. The telescopic rod is installed in the second boss. The clamping block is connected to the movable end of the telescopic rod, and the positioning block is connected to the first boss. The telescopic rod includes a screw and a hollow tube. The screw is rotatably connected to the second boss. One end of the screw extends out of the second boss and is connected to a knob. The screw and the hollow tube are connected by a thread. The hollow tube is fixedly connected to the clamping block, and the hollow tube and the second boss are slidably connected by a groove. When the first and second bosses are in contact, the positioning block enters the cavity. Rotating the screw can drive the clamping block to move, thereby clamping the positioning block.

[0006] Furthermore, when the clamping block clamps the positioning block, the contact surface between the clamping block and the positioning block is an inclined surface.

[0007] Furthermore, a support block is provided inside the cavity of the second boss, and a support arc surface is provided on the support block. During the process of the positioning block moving in and out of the second boss, the support block fits with the positioning block through the support arc surface.

[0008] Furthermore, a guide ramp is provided on the lower side of the positioning block.

[0009] The beneficial effects of this utility model are as follows:

[0010] Rotating the knob can cause the clamping block to press against the positioning block, so that the first boss and the second boss are connected by the locking component, which makes the assembly more efficient, simple to operate, and requires less operating space.

[0018] The present invention provides the following specific embodiments:

[0019] like Figure 1-4 As shown, this utility model provides a sanitary clamp connector, including an upper clamp 1 and a lower clamp 2. One end of the upper clamp 1 is rotatably connected to the lower clamp 2. A first boss 7 is provided at the non-rotating end of the upper clamp 1, and a second boss 8 is provided at the non-rotating end of the lower clamp 2. A locking assembly 5 is provided between the first boss 7 and the second boss 8. The second boss 8 has an upward-opening cavity. The locking assembly 5 includes a pressing block 5.3, a positioning block 5.4, and a telescopic rod. The telescopic rod is installed in the second boss 8. The pressing block 5.3 is connected to the movable end of the telescopic rod, and the positioning block 5.4 is connected to the first boss 7. The telescopic rod includes a screw 5.1 and a hollow tube 5.2. The screw 5.1 is connected to the second boss 7. The screw 5.1 is rotatably connected to the second boss 8. One end of the screw 5.1 extends out of the second boss 8 and is connected to a knob. The screw 5.1 is threadedly connected to the hollow tube 5.2. The hollow tube 5.2 is fixedly connected to the clamping block 5.3. The hollow tube 5.2 is slidably connected to the second boss 8 through a groove. When the first boss 7 and the second boss 8 are in contact, the positioning block 5.4 enters the cavity. Rotating the knob drives the screw 5.1 to rotate. The threaded connection between the screw 5.1 and the hollow tube 5.2, combined with the groove connection between the hollow tube 5.2 and the second boss 8, can drive the clamping block 5.3 to move linearly, ultimately causing the clamping block 5.3 to press the positioning block 5.4 to complete the locking between the upper clamp 1 and the lower clamp 2.

[0020] Furthermore, there will be no relative movement between the screw 5.1 and the second boss 8 in the axial direction.

[0021] Furthermore, when the clamping block 5.3 clamps the positioning block 5.4, the contact surface between the clamping block 5.3 and the positioning block 5.4 is an inclined surface, so that the clamping block 5.3 can apply a preload to the positioning block 5.4.

[0022] Furthermore, a support block 5.5 is provided inside the cavity of the second boss 8. The support block 5.5 has a support arc surface. Correspondingly, the side of the positioning block 5.4 near the support block 5.5 is an arc surface. During the process of the positioning block 5.4 moving in and out of the second boss 8, the support block 5.5 fits against the positioning block 5.4 through the support arc surface. In addition, during the process of the pressing block 5.3 squeezing the positioning block 5.4, the support block 5.5 can provide support for the positioning hole to prevent it from deforming.

[0023] Furthermore, a guide slope 5.41 is provided on the lower side of the positioning block 5.4 to prevent collision between the positioning block 5.4 and the support block 5.5.

[0024] In use, first assemble the first pair of connecting pipes 3, the second pair of connecting pipes 4, and the sealing ring 6. Then, put the upper half clamp 1 and the lower half clamp 2 around the joint. Rotate the upper half clamp 1 or the lower half clamp 2 to make the first boss 7 and the second boss 8 fit together. Then, rotate the knob to make the clamping block 5.3 press the positioning block 5.4 to complete the fixation of the relative position between the upper half clamp 1 and the lower half clamp 2. When disassembling, rotate the knob to make the clamping block 5.3 in a position that does not affect the positioning block 5.4 from disengaging from the second boss 8. Then, separate the first boss 7 and the second boss 8.

[0025] Rotating the knob can cause the clamping block 5.3 to clamp the positioning block 5.4, so that the first boss 7 and the second boss 8 are connected by the locking component 5. Compared with the traditional bolt connection, the step of aligning the bolt with the bolt hole is eliminated, the assembly efficiency is higher, the operation is simple, and the requirements for operating space are lower.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
