Quick cable joint for fruit and vegetable sales display equipment

Abstract

The utility model discloses a quick cable connector for fruit and vegetable sales display equipment, and relates to the field of quick cable connectors. The connector comprises a male head assembly, a female head assembly and a male head sleeve shell, and the outer side of the female head sleeve shell is provided with a first connecting module and a second connecting module respectively. The first connecting module, the second connecting module, a movable lantern ring and the male head sleeve shell, and a nut lantern ring and the female head sleeve shell are movably connected; the movable lantern ring and the nut lantern ring can rotate freely relative to the male head sleeve shell and the female head sleeve shell, when the male head sleeve shell and the female head sleeve shell rotate relatively under the action of external force, the rotation cannot be directly transmitted to the movable lantern ring and the nut lantern ring, and meanwhile the movable lantern ring and the nut lantern ring can rotate freely. Due to the fact that connection between the movable lantern ring and the nut lantern ring is achieved through threads, the influence of external rotation on threaded connection is reduced through the movable state between the movable lantern ring and the nut lantern ring, and the loosening risk caused by external rotation is effectively reduced through the design.

Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cable quick connector, concretely to a kind of fruit and vegetable sales display equipment quick cable joint. BACKGROUND

[0002] The selection of fruit and vegetable sales display equipment quick cable joint is crucial, and the use environment, cable type, installation convenience and safety reliability should be considered comprehensively. For outdoor or mobile equipment, waterproof and dustproof outdoor connector should be selected. According to the cable core material, the matching connector material is selected. The quick cable joint should be convenient to install and disassemble to ensure the safety and stability of the circuit. According to the patent with the publication number CN218448742U3, a "welding cable quick connector with secondary fastening" is proposed. The design innovatively uses a movable nut mechanism to enhance the stability of the connection and the tensile strength of the cable by secondary fastening of the male and female connectors. However, in practical applications, this design faces a challenge. For quick connectors that need to be frequently plugged and unplugged, the design of the movable nut is flexible but susceptible to external forces, which can cause the male and female connectors to rotate or the nut to loosen. This phenomenon weakens the anti-loosening effect of the traditional nut secondary fastening method, affecting the stability of the connector and reducing the convenience and reliability of the quick cable joint in daily use. SUMMARY

[0003] Therefore, the utility model aims to provide a fruit and vegetable sales display equipment quick cable joint to solve the technical problem of poor anti-loosening effect of the traditional nut secondary fastening method.

[0005] The first connection module comprises a movable sleeve ring, and the movable sleeve ring is movably sleeved on the outside of the male connector shell. The second connection module comprises a nut sleeve ring, one side of the nut sleeve ring is provided with a limiting edge, and the nut sleeve ring is threadedly connected with the movable sleeve ring. The outside of the first connection module and the second connection module is provided with a clamping ring for limiting the relative rotation of the nut sleeve ring and the movable sleeve ring.

[0006] By adopting the above-mentioned technical scheme, even if the male connector shell and the female connector shell rotate relative to each other due to external factors during the use of the connector, this rotation will not be directly transmitted to the movable sleeve ring and the nut sleeve ring. This is because the movable connection allows a certain degree of freedom, which can maintain the position stable relatively independently.

[0007] Further, one side of the movable sleeve ring is fixedly connected with a hexagonal block, and the outer side of the nut sleeve ring is in a hexagonal structure and is consistent in size with the hexagonal block.

[0009] Further, the inner side of the clamping ring is provided with a clamping groove in a hexagonal structure, and the clamping groove is sleeved and clamped with the nut sleeve ring and the hexagonal block.

[0010] By adopting the above technical scheme, additional fixing force is provided for the connection of the movable sleeve ring and the nut sleeve ring. This clamping method not only effectively prevents connection loosening caused by vibration or external force, but also maintains the stability of the joint in extreme environments, ensuring the continuous reliability of the cable connection.

[0011] Further, one side of the clamping ring is provided with a side ring for limiting the position of the clamping ring, and the limiting edge is used for limiting the position of the nut sleeve ring.

[0012] By adopting the above technical scheme, the existence of the side ring effectively limits the movement of the clamping ring in the axial direction, preventing the clamping ring from falling off or shifting due to external force.

[0013] Further, the material of the first and second connection modules is insulating plastic, and the material of the clamping ring is rubber.

[0014] By adopting the above technical scheme, the insulating plastic material ensures the insulation performance of the joint during electrical connection, effectively preventing safety accidents caused by electrical short circuit. At the same time, the insulating plastic material also has good corrosion resistance and wear resistance, which can keep the appearance and performance of the joint stable for a long time.

[0015] Further, the male head assembly comprises a male head body, one side of the male head body is fixedly provided with a plug, and the plug is provided with a clamping block, the female head assembly comprises a female head body, the inner side of the female head body is formed with a through groove, the plug extends into the inner side of the through groove and is clamped with the inner side clamping groove through the clamping block.

[0016] By adopting the above technical scheme, the tight connection and firm clamping between the male head assembly and the female head assembly are realized. This clamping method not only is easy to operate, but also effectively prevents the joint from falling off or loosening due to external force, ensuring the long-term stability and reliability of the cable connection.

[0017] In summary, the utility model mainly has the following beneficial effects:

[0018] 1、 the utility model discloses a first connecting module, second connecting module, the movable sleeve ring and the male head shell and the nut sleeve ring and female head shell between the movable connection design, make movable sleeve ring and nut sleeve ring can rotate freely relative to male head shell and female head shell, allow male head shell and female head shell when being subjected to external force and relatively rotating, this rotation does not directly transmit to movable sleeve ring and nut sleeve ring, simultaneously, because the connection between movable sleeve ring and nut sleeve ring is realized through the thread, and the movable state between both reduces the influence of external rotation on threaded connection, therefore this design effectively reduces the looseness risk produced because of external rotation;

[0019] 2、 the utility model discloses setting the clamping ring, clamping ring is clamped in movable sleeve ring and the outside of nut sleeve ring, and this operation provides additional fixing force for the connection of movable sleeve ring and nut sleeve ring through the physical clamping mode, and the hexagonal clamping groove designed in the inside of clamping ring and the hexagonal structure of the outside of nut sleeve ring and the size of hexagonal block are matched, realize accurate clamping, not only further strengthen the relative position fixation between movable sleeve ring and nut sleeve ring, still through the mode of increasing physical clamping point, effectively improve the anti-loose effect of joint.
