Description

Technical Field

[0001] This invention relates to the field of anti-detachment devices, and more specifically, to a U-shaped pin anti-detachment device. Background Technology

[0002] U-pins are commonly used fixing devices for pipeline connections in underground coal mine equipment. The reliability of U-pins is crucial to the overall stability of mining equipment. In actual use, U-pins, as metal fasteners, are rigid metal connections used with joints and other connecting ends. However, due to vibrations in the equipment, U-pins may fall off, causing safety hazards such as joint connection failure.

[0003] In conclusion, how to prevent U-pins from falling off is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a U-pin anti-detachment device, which effectively ensures that the U-pin cannot fall off, and has a simple structure, light weight, and is easy for operators to install.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A U-pin anti-detachment device for fixing a connector and a U-pin, comprising:

[0007] Mounting base, which has a mounting part for mounting U-shaped pins;

[0008] Two clamping leg structures are disposed on the mounting base, and the free ends of the two clamping leg structures can move towards each other or away from each other, for use in cooperating with the connector to fix or adjust the mounting base.

[0009] Preferably, the clamping leg structure is a rigid component, the inner circumferential surface of the clamping leg structure is an arc-shaped surface, and the inner circumferential surfaces of the two clamping leg structures are arranged opposite to each other.

[0010] Preferably, the two clamping leg structures have an opening and closing part in the middle, so that the width of the opening in the middle of the two clamping leg structures can be adjusted.

[0011] Preferably, the clamping leg structure is an elastic element, which can be elastically deformed to be fitted onto the connector.

[0012] Preferably, the free end of the clamping leg structure is provided with a fixing part;

[0013] It also includes a spring, with both ends of the spring respectively disposed at the fixing part of the two clamping leg structures.

[0014] Preferably, the mounting part is a U-shaped groove, and the U-shaped pin is engaged with the U-shaped groove, and the clamping leg structure is parallel to the depth direction of the U-shaped groove.

[0015] Preferably, the two clamping leg structures are located on the side of the mounting part, the U-shaped pin connects the first connector and the second connector, the second connector is inserted into the first connector, and the clamping leg structure is clamped onto the circumferential surface of the second connector.

[0016] Preferably, both the mounting base and the clamping leg structure are fire-resistant and flame-retardant components.

[0017] Preferably, the mounting base is provided with a hanging part for suspending or connecting the U-shaped pin anti-detachment device.

[0018] The U-shaped pin anti-detachment device provided by this invention has a mounting base that supports the U-shaped pin. In use, the U-shaped pin is installed on the mounting part. The root of the clamping leg structure is fixed on the mounting base, and the head of the clamping leg structure is a free end. When the free ends of the two clamping leg structures move away from each other, the opening between the two clamping leg structures becomes larger, so that the connector can enter the middle of the two clamping leg structures from the opening. When the free ends of the two clamping leg structures move towards each other, the opening between the two clamping leg structures becomes smaller, and the connector cannot detach under the restriction of the two clamping leg structures, thereby fixing the fixing base on the connector.

[0019] During assembly, move the mounting base so that the U-shaped pin is installed on the mounting part. Move the free end of the clamping leg structure so that it moves away from the mounting point, insert the connector between the two clamping leg structures, and move the free ends of the clamping leg structures so that they move towards each other, reducing the opening between the two clamping leg structures. Then, fit the connector inside the two clamping leg structures, thus securing the mounting base. This U-shaped pin anti-detachment device effectively prevents the U-shaped pin from falling off, and its simple structure and light weight make it easy for operators to install.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The core of this invention is to provide a U-shaped pin anti-detachment device, which effectively ensures that the U-shaped pin cannot fall off, and has a simple structure, light weight, and is easy for operators to install.

[0028] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram illustrating the use of a specific embodiment provided by the present invention; Figure 2 This is a schematic diagram of the structure of a specific embodiment provided by the present invention; Figure 3 This is a structural schematic diagram from another angle of a specific embodiment provided by the present invention.

[0029] This invention provides a U-shaped pin anti-detachment device for fixing a connector and a U-shaped pin 3, comprising a mounting base 1 and two clamping leg structures 2. The mounting base 1 has a mounting portion 1-1 for mounting the U-shaped pin 3; the clamping leg structures 2 are disposed on the mounting base 1, and the free ends of the two clamping leg structures 2 can move towards or away from each other, for fitting together on the connector to fix or adjust the mounting base 1.

[0030] Specifically, such as Figure 1 As shown, the mounting base 1 serves to support the U-shaped pin 3. In use, the U-shaped pin 3 is installed on the mounting part 1-1. It should be noted that the specific types of the mounting base 1 and the mounting part 1-1 are not limited, as long as they can perform the above functions.

[0031] like Figure 2 and Figure 3As shown, the root of the clamping leg structure 2 is fixed on the mounting base 1, and the head of the clamping leg structure 2 is the free end. When the free ends of the two clamping leg structures 2 move away from each other, the opening between the two clamping leg structures 2 becomes larger, so that the connector can enter the middle of the two clamping leg structures 2 from the opening; when the free ends of the two clamping leg structures 2 move towards each other, the opening between the two clamping leg structures 2 becomes smaller, and the connector cannot be separated under the restriction of the two clamping leg structures 2, thereby fixing the fixing base on the connector.

[0032] The assembly process is as follows: Move the mounting base 1 so that the U-shaped pin 3 is installed on the mounting part 1-1. Move the free end of the clamping leg structure 2 so that it moves away from the mounting base. Insert the connector into the middle of the two clamping leg structures 2. Move the free end of the clamping leg structure 2 so that it moves towards the mounting base 2, reducing the opening between the two clamping leg structures 2. Fit the connector inside the two clamping leg structures 2, thereby fixing the mounting base 1. This U-shaped pin anti-detachment device effectively prevents the U-shaped pin 3 from falling off. It has a simple structure, is lightweight, and is easy for operators to install.

[0033] Based on the above embodiments, the leg clamping structure 2 is a rigid component, the inner circumferential surface of the leg clamping structure 2 is an arc-shaped surface, and the inner circumferential surfaces of the two leg clamping structures 2 are arranged opposite to each other.

[0034] Specifically, the inner circumferential surfaces of the two clamping leg structures 2 form a ring with a small gap. In use, the U-shaped pin anti-detachment device is pushed radially along the joint so that the openings of the two clamping leg structures 2 are aligned with the joint. During the pushing process, the openings of the two clamping leg structures 2 open, and finally the U-shaped pin anti-detachment device is sleeved on the outside of the joint, thereby fixing the U-shaped pin anti-detachment device. As a result, the U-shaped pin 3 installed on the mounting base 1 is fixed, preventing the U-shaped pin 3 from falling off. The assembly process is simple and convenient.

[0035] Furthermore, the two locking leg structures 2 are rotatable through a pivot structure, thereby avoiding the situation where the openings of the two locking leg structures 2 are not wide enough and installation cannot be successful.

[0036] Based on the above embodiment, an opening / closing portion 2-1 is provided between the two locking leg structures 2, so that the width of the opening between the two locking leg structures 2 can be adjusted. Specifically, as shown... Figure 2 and Figure 3 As shown, the opening and closing part 2-1 is a through groove. Preferably, the bottom of the through groove is arc-shaped, which effectively prevents the two locking leg structures 2 from breaking and failing when opened. In use, when the two locking leg structures 2 open, the opening and closing part 2-1 also opens. After the U-shaped pin anti-detachment device is assembled into the preset position, the opening and closing part 2-1 helps the two locking leg structures 2 to return to their original state.

[0037] Based on the above embodiments, the clamping leg structure 2 is an elastic element, which can be sleeved onto the connector through elastic deformation. In use, the clamping leg structure 2 is sleeved onto the circumference of the connector to fix the U-shaped pin anti-detachment device. Since the clamping leg structure 2 is an elastic element, the U-shaped pin anti-detachment device can be installed in any way, such as sleeved onto the outside of the connector along the radial or axial direction, and the U-shaped head of the U-shaped pin 3 is installed in the mounting part 1-1. This U-shaped pin anti-detachment device is easy to assemble and beneficial for practical use.

[0038] Based on the above embodiment, the free end of the clamping leg structure 2 is provided with a fixing part; it also includes a spring, with both ends of the spring respectively disposed at the fixing parts of the two clamping leg structures 2.

[0039] Specifically, the fixing part is a through hole or a groove of any shape. In use, the hooks at both ends of the spring are hooked onto the fixing parts of the two clamping leg structures 2 respectively, thereby fixing the two clamping leg structures 2, so that the U-shaped pin anti-detachment device is stably fixed and not easy to fall off, thus improving the stability of the joint connection.

[0040] Based on any of the above embodiments, the mounting part 1-1 is a U-shaped groove, and the U-shaped pin 3 is engaged in the U-shaped groove, with the locking leg structure 2 parallel to the depth direction of the U-shaped groove. In use, the U-shaped groove covers the U-shaped pin 3, effectively preventing debris from falling between the U-shaped pin 3 and the connector, and preventing the two connectors connected by the U-shaped pin 3 from loosening or even failing. Preferably, the U-shaped grooves are of the same size, and when the U-shaped pin anti-detachment device is installed in the preset position, the U-shaped pin 3 and the U-shaped groove are in a transitional fit, resulting in a tight connection and excellent debris-blocking function.

[0041] Based on the above embodiment, two clamping leg structures 2 are located on the side of the mounting part 1-1, and a U-shaped pin 3 connects the first connector 4-1 and the second connector 4-2. The second connector 4-2 is inserted into the first connector 4-1, and the clamping leg structure 2 is clamped onto the circumferential surface of the second connector 4-2.

[0042] Specifically, such as Figure 2 and Figure 3 As shown, the clamping leg structure 2 is located on the side of the mounting part 1-1. In use, as... Figure 1 As shown, two clamping leg structures 2 are sleeved on the circumferential surface of the second connector 4-2. Since the second connector 4-2 is inserted into the inside of the first connector 4-1, the two clamping leg structures 2 are located on the end face of the first connector 4-1, effectively preventing impurities from entering the gap between the first connector 4-1 and the second connector 4-2, and preventing the connection between the first connector 4-1 and the second connector 4-2 from being unstable.

[0043] Based on any of the above embodiments, both the mounting base 1 and the locking leg structure 2 are fire-resistant and flame-retardant components. Specifically, the U-shaped pin anti-detachment device is made of fire-resistant and flame-retardant materials, making it suitable for special workplaces with flammable and explosive environments, and extending its service life.

[0044] Furthermore, depending on the specifications, the U-shaped pin anti-detachment device can be made in different colors, such as by adding pigments during the manufacturing process before it is formed, or by painting it after it is made, so as to make it easy to distinguish and convenient to use.

[0045] Based on any of the above embodiments, the mounting base 1 is provided with a hanging part 1-2 for suspending or connecting the U-shaped pin anti-detachment devices. Specifically, the hanging part 1-2 is a through hole or groove, etc., and the hanging part 1-2 is set at any position without destroying the function of the U-shaped pin anti-detachment device in fixing the U-shaped pin 3 and the connector. When the U-shaped pin anti-detachment device is not in use, it can be suspended, or the U-shaped pin anti-detachment devices can be strung together for easy sorting and storage.

[0046] It should be noted that the terms "upper surface," "lower surface," "top," and "bottom" mentioned above, as well as the directional terms "upper," "lower," "left," and "right," are defined based on the accompanying drawings in the instruction manual.

[0047] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Specific examples have been used to illustrate the principle and implementation of the invention. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principle of the invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
