Description

Technical Field

[0001] The utility model belongs to the field of mechanical anti-loosening structure design, in particular to a latch-type anti-loosening mechanism with a simple structure. Background Art

[0002] When transport packaging equipment is loading cylindrical contents, it is generally fixed with a load-bearing bracket and a pressure plate, and then pre-tightened with a handle bolt after fixation. During actual transportation, due to the presence of transportation vibration, anti-loosening measures need to be taken for the handle bolt to prevent loosening caused by vibration, which in turn affects the transportation safety of the contents. Previous anti-loosening measures mostly used spring washers to prevent loosening or iron wire winding to prevent physical loosening. Both of these anti-loosening methods have certain disadvantages. For example, spring washers have poor anti-loosening effects and are difficult to adapt to long-distance transportation scenarios. Iron wire winding is not convenient enough for anti-loosening, and installation and disassembly are time-consuming and labor-intensive. Therefore, there is an urgent need for a reliable and convenient handle bolt anti-loosening mechanism to achieve anti-loosening work after the contents are fixed. Utility Model Content

[0003] Purpose of the utility model: To propose a simple latch-type anti-loosening mechanism, which can improve the anti-loosening effect of the handle bolt and avoid loosening caused by vibration; reduce the anti-loosening workload and improve work efficiency; the mechanism is simple and compact, meeting the small size space requirements of the pressure plate.

[0004] Technical solution: A simple latch-type anti-loosening mechanism mainly consists of an outer stop, an inner stop, a bent latch, and a socket wrench; the outer stop and the inner stop are respectively arranged outward along the periphery of the socket wrench, and a blind hole is opened at the bottom of the socket of the socket wrench. The bent latch passes through the outer stop and the inner stop in turn and is inserted into the blind hole of the socket wrench to achieve the limiting of the socket wrench.

[0005] Furthermore, the outer stopper and the inner stopper are both fixed on a platform.

[0006] Furthermore, the outer stopper is provided with a U-shaped groove.

[0007] Furthermore, there is a certain gap between the outer stopper and the inner stopper, and the gap can accommodate the bending pin.

[0008] Furthermore, the inner stopper adopts an arc-shaped structure and fits with the socket of the socket wrench.

[0009] Furthermore, the outer stopper and the inner stopper are both integrally machined.

[0010] Working principle: In the anti-loosening mechanism, the outer stop and the inner stop are used to prevent the bent pin from falling out after it is installed; blind holes are evenly opened at the bottom of the socket wrench sleeve to cooperate with the bent pin for positioning; the inner stop and the socket wrench are positioned together, and the bent pin is inserted into the hole at the bottom of the socket wrench to achieve positioning and prevent the socket wrench from rotating, thereby achieving the purpose of preventing loosening after fixing.

[0011] Technical effect: The utility model has a simple structure and high reliability. When used, it can significantly improve the anti-loosening effect of the handle bolt and avoid loosening caused by vibration; reduce the anti-loosening workload and improve work efficiency; the mechanism is simple and compact, meeting the small size space requirements of the pressure plate.

[0015] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings or specific implementation cases. It should be noted that some (but not all) of the disclosed examples are shown in the drawings. In fact, many different examples can be described and these examples should not be understood as being limited to the examples set forth herein. On the contrary, describing these examples makes the positive effects of the present invention more apparent, and any parts not detailed herein are considered to be well-known techniques or conventional technical means in the art.

[0016] See attached Figure 1 A simple latch-type anti-loosening mechanism is specifically designed, and is mainly composed of four parts: an outer stopper 1, an inner stopper 2, a bent latch 3, and a socket wrench 4. The outer stopper 1 and the inner stopper 2 are integrally machined to prevent the bent latch 3 from falling out after installation; blind holes are evenly opened at the bottom of the sleeve of the socket wrench 4 to cooperate with the bent latch 3 for positioning; the inner stopper 2 and the socket wrench 4 are positioned together, and the bent latch 3 is inserted into the hole at the bottom of the socket wrench 4 to achieve a limit position, preventing the socket wrench 4 from rotating, thereby achieving the purpose of preventing loosening after fixing.

[0017] The anti-loosening mechanism is installed on the side of the socket wrench 4, and the maximum width of the anti-loosening mechanism is limited to within 80% of the diameter of the socket wrench 4.

[0018] The bottom of the socket wrench 4 has holes evenly spaced, with a diameter that matches the diameter of the 3-bend wrench and maintains a clearance fit. The middle of the inner stopper 2 has a hole with a diameter that matches the socket wrench 4. The upper half of the outer stopper 1 has a U-shaped groove with a width that matches the diameter of the socket wrench 4.

[0019] When in use, first rotate the socket wrench 4 to lock the pressure plate, and align the socket wrench 4 with the opening of the inner stop 2, insert the bent pin 3 from the U-shaped groove of the outer stop 1 until the bent part of the pin touches the inner stop 2, and lower the bent part of the bent pin 3 to complete the anti-loosening operation.

[0020] The above specific implementation methods or cases are only used to explain the technical solutions of the utility model and are not intended to limit the present application. Any parts not described in detail are regarded as conventional technical means or common knowledge in the field. It can be understood by ordinary technicians in this field that: based on the design concept of the present application, it should be possible to adaptively modify the technical solutions recorded in the aforementioned implementation methods, or to replace some or all of the technical features therein by equivalents. These modifications, equivalent replacements, and adaptively improved technical solutions do not depart from the technical essence of the utility model and should all be covered by the protection scope of the present application.
