Description

Technical Field

[0001] This utility model relates to the field of stepless clamp technology, specifically to a single-ear stepless clamp buckle anti-detachment structure. Background Technology

[0002] Single-ear stepless clamp is a type of fastener widely used for pipe connections, mainly for connecting flexible hoses and rigid pipes. By designing the inner ring of the clamp to be free of protrusions and gaps, it can achieve a sealed connection between pipes through 360° uniform force distribution.

[0003] When connecting flexible hoses and rigid pipes, common single-ear stepless clamps can vibrate under pressure pulsation in a pulsating environment due to the continuous impact of the medium on some hoses. This can cause the stepless clamp to fail due to fatigue. Therefore, in order to improve the fastening effect of single-ear stepless clamps, protrusions or hook interlocking devices are designed to improve the contact effect and increase stability.

[0004] However, some single-ear stepless clamps are narrow in width. When they come into contact with the hose and provide a limiting effect, they are subjected to impact and vibration amplification, which increases the probability of fatigue failure and affects the fastening effect of the single-ear clamp. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a single-ear stepless clamp buckle anti-detachment structure to improve the fatigue resistance of the single-ear stepless clamp when subjected to impact and reduce the probability of fatigue failure.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a single-ear stepless clamp buckle anti-detachment structure, including a clamp body, an arc-shaped connecting plate sleeved on one side of the clamp body, a first groove opened on one side of the arc-shaped connecting plate, a recess opened on the side of the arc-shaped connecting plate located in the first groove, the recess contacting the clamp body and having the same width, an arc-shaped locking strip fixedly connected to the arc-shaped connecting plate near the central axis of the clamp body, the arc-shaped locking strip having evenly spaced gaps, and the cross-section of the arc-shaped locking strip having a triangular structure.

[0007] As a preferred technical solution of this utility model, the arc-shaped connecting plate is uniformly and fixedly connected with protrusions in the recess, and the protrusions are inserted into the clamp body. By setting the protrusions to cooperate with the clamp body, the clamp body can be easily and stably positioned.

[0008] As a preferred technical solution of this utility model, an extension rod is threadedly connected to one side of the arc-shaped connecting plate, an extension plate is sleeved on the extension rod, and a rubber sheet is glued to the side of the extension plate away from the arc-shaped connecting plate. By setting the extension rod and the extension plate, the support surface of the clamp connecting pipe fitting can be further increased, and the connection stability can be improved.

[0009] As a preferred technical solution of this utility model, a spring is in contact with one side of the extension plate, the spring is sleeved on the extension rod, and one end of the spring is in contact with the side of the arc-shaped connecting plate away from the first groove. By setting the spring, the shaking can be dispersed.

[0010] As a preferred technical solution of this utility model, a longitudinal locking strip is fixedly connected to the side of the arc-shaped connecting plate near the central axis of the clamp body. The longitudinal locking strip is located at the gap, and an arc-shaped surface is opened at the end of the longitudinal locking strip away from the arc-shaped connecting plate. By setting the longitudinal locking strip, the friction is further increased, making the contact more stable.

[0011] This utility model has the following advantages: by setting three detachable arc-shaped connecting plates on the clamp body, and cooperating with arc-shaped clamp strips, extension plates and longitudinal clamp strips, the pressure between the clamp body and the pipe can be increased when the clamp body is pressed, thereby increasing the contact surface between the clamp body and the pipe, and at the same time increasing the pressure, improving the stable anti-loosening effect.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to the following: Figure 1-3The single-ear stepless clamp anti-detachment structure shown includes a clamp body 1, an arc-shaped connecting plate 2 sleeved on one side of the clamp body 1, a first groove 3 on one side of the arc-shaped connecting plate 2, and a recess 4 on one side of the arc-shaped connecting plate 2 located in the first groove 3. By setting the recess 4 to contact the clamp body 1, it can tightly prevent detachment when the clamp body 1 is pressed. The recess 4 contacts the clamp body 1 and has the same width. An arc-shaped locking strip 5 is fixedly connected to the arc-shaped connecting plate 2 near the central axis of the clamp body 1. The arc-shaped locking strip 5 increases the pressure when the clamp body 1 is pressed, which can further provide a pressing effect. The arc-shaped locking strip 5 has evenly spaced gaps and the cross-section of the arc-shaped locking strip 5 has a triangular structure.

[0016] The arc-shaped connecting plate 2 is uniformly fixedly connected with protrusions 6 in the recess 4. The protrusions 6 are inserted into the clamp body 1. By setting the protrusions 6, the gaps on the clamp body 1 are connected, which can promote the relative stability between the clamp body 1 and the arc-shaped connecting plate 2.

[0017] The arc-shaped connecting plate 2 is threaded with an extension rod 7 on one side, and an extension plate 8 is sleeved on the extension rod 7. A rubber sheet is glued to the side of the extension plate 8 away from the arc-shaped connecting plate 2. By setting the extension rod 7 and the extension plate 8, the contact surface between the arc-shaped connecting plate 2 and the pipe fitting to be fastened can be increased, thereby improving the connection stability.

[0018] One side of the extension plate 8 is in contact with a spring 9, which is sleeved on the extension rod 7. One end of the spring 9 is in contact with the side of the arc-shaped connecting plate 2 away from the first groove 3. By setting the spring 9, the extension plate 8 can be made to contact the end of the extension rod 7, thereby making the extension plate 8 and one end of the extension rod 7 connected, which can improve the stability of the extension plate 8 and provide an energy release effect.

[0019] Among them, the arc-shaped connecting plate 2 is fixedly connected to the longitudinal clamp strip 10 on the side near the central axis of the clamp body 1. The longitudinal clamp strip 10 is located in the gap. The end of the longitudinal clamp strip 10 away from the arc-shaped connecting plate 2 has an arc-shaped surface. By setting the longitudinal clamp strip 10, the stability of the clamp body 1 can be further improved by connecting the pipe fittings to be tightened.

[0020] Working principle: When clamps are required and there is sufficient contact surface, the arc-shaped connecting plate 2 is connected to the clamp body 1, and the clamp body 1 and the recess 4 are in corresponding contact. The protrusion 6 is inserted into the side of the clamp body 1 to further tighten the clamp. The arc-shaped clamp 5 and the longitudinal clamp 10 further tighten the pipe fitting to be fastened. Then, the extension rod 7 and the extension plate 8 are installed, which can further increase the contact surface between the clamp body 1 and the pipe fitting, and improve the stable connection effect.

[0021] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
