Description

Technical Field

[0001] The utility model relates to the field of connecting components, in particular to a pin connector. Background Art

[0002] Pin couplings achieve connection by nesting and fixing pins together. They are widely used in mechanical equipment and tools. They can be used to connect various mechanical parts and transmit force, and are an important mechanical component.

[0003] The application of the pin coupling can make the machine run more smoothly. This component helps to reduce the failure rate of the machine by enhancing the connection stability of the machine. It plays a key role in improving mechanical performance and stability. When used on the pin shaft, the two half-couplings are connected by a pin, and a baffle is connected to the outside through multiple sets of bolts to prevent the pin from running out. However, when connecting the various positions of the baffle to the half-coupling in turn, if pre-positioning is not performed, there is still a risk of baffle offset during the connection process. When there is a connection deviation, the overall stability of the component is easily reduced. Utility Model Content

[0004] The utility model aims at the deficiencies in the prior art and provides a pin coupling, in which first clamping blocks are installed at the upper and lower ends of the baffle plate that are attached to one side of the half coupling, and first clamping grooves are opened at the upper and lower ends of the half coupling corresponding to one side of the first clamping block. When the two are butted and attached, the first clamping block is driven to be inserted into the first clamping groove, and the pre-positioning treatment is carried out, thereby avoiding deviations in the subsequent connection process and reducing the overall stability of the components.

[0005] In order to solve the above technical problems, the present invention solves the problem that if no pre-positioning treatment is performed, the baffle may be offset during the connection process, and when there is a connection deviation, the overall stability of the component may be easily reduced.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A pin coupling comprises a pin rod, a half coupling and a baffle, wherein two groups of the half couplings and the baffle are provided, and the half couplings and the baffle are arranged on the pin rod, and the two groups of the half couplings are connected by a pin, and a first clamping block is provided on the side of the baffle close to the half coupling, and a first clamping groove is opened on the side of the half coupling close to the baffle.

[0008] Preferably, one end of the first clamping block is mounted on the baffle, and the other end is correspondingly inserted into the first clamping slot.

[0009] Preferably, a second clamping block is provided on a side of the half coupling close to the baffle, and a second clamping groove is provided on a side of the baffle close to the half coupling.

[0010] Preferably, one end of the second clamping block is mounted on the half coupling, and the other end is correspondingly inserted into the second clamping slot.

[0011] Preferably, four groups of the first clamping block, the first clamping slot, the second clamping block and the second clamping slot are provided.

[0012] Preferably, the first clamping block and the second clamping block are staggered, and the first clamping slot and the second clamping slot are staggered.

[0013] Preferably, it further comprises a sealing ring arranged between the half coupling and the baffle, and an annular positioning groove for inserting the sealing ring is provided between the baffle and the half coupling.

[0014] Preferably, one side of the half coupling is connected to a limiting collar sleeved on the outer ring of the baffle.

[0015] Preferably, an inner clamping groove is provided between the two groups of half couplings, an inner pressure ring is provided inside the inner clamping groove, and positioning clamping rings are connected to both ends of the inner pressure ring.

[0016] Preferably, the inner pressure ring is inserted into the inner card slot through a positioning clamp ring.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The pin coupling provided in the present application is characterized in that a first clamping block is installed on the upper and lower ends of the baffle that is attached to one side of the half-coupling, and a first clamping groove is opened on the upper and lower ends of the half-coupling corresponding to the first clamping block. When the two are docked and attached, the first clamping block is driven to be inserted into the first clamping groove, and the pre-positioning process is carried out, while avoiding deviations in the subsequent connection process, which reduces the overall stability of the components.

[0019] The present application sets a second clamping block and a second clamping slot, wherein the first clamping block and the second clamping block are staggered and their insertion ends are directed in opposite directions. Therefore, during the positioning process, the stability of the connection on the other side during the connection between the half coupling and the baffle can be further improved.

[0020] The present application provides an annular positioning groove and a sealing ring, so that after the sealing ring is inserted into the annular positioning groove, the two are interference fit when plugged in, and when installed, it surrounds the outer rings of the first and second clamping blocks to further improve the sealing of the connection.

[0021] This application provides a limiting ring, which is sleeved onto the outside of the baffle and fits against its outer wall, thereby further limiting the connection surface between the baffle and the half-coupling. BRIEF DESCRIPTION OF THE DRAWINGS

Example

[0035] See also Figure 1-7 A pin coupling includes a pin rod 1, a half coupling 101 and a baffle 102. Two groups of half couplings 101 and baffle 102 are provided, and the half couplings 101 and baffle 102 are provided on the pin rod 1. The two groups of half couplings 101 are connected by a pin 103. A first clamping block 104 is provided on the side of the baffle 102 close to the half coupling 101, and a first clamping groove 105 is provided on the side of the half coupling 101 close to the baffle 102.

[0036] Some embodiments of the present application are described in detail below with reference to the accompanying drawings:

[0037] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The pin coupling of the present application is mainly composed of parts such as the pin rod 1, the half coupling 101, the baffle 102 and the pin 103. It is located on the pin rod 1 and connects the two half couplings 101 through multiple groups of pins 103. After the connection, the baffle 102 is connected to the outside through multiple groups of bolts to prevent the pin 103 from running out. When the various positions on the baffle 102 are connected to the half coupling 101 in turn, a first clamping block 104 is installed at the upper and lower ends of the baffle 102 that is attached to one side of the half coupling 101. A first clamping groove 105 is opened on the upper and lower ends of the half coupling 101 corresponding to the first clamping block 104. When the two are docked and attached, the first clamping block 104 is driven to be inserted into the first clamping groove 105. While pre-positioning, it avoids deviation in the subsequent connection process, which reduces the problem of reducing the overall stability of the components.

[0038] In some embodiments, second clamping blocks 106 are installed on the upper and lower ends of the half-coupling 101 that are attached to one side of the baffle 102, and second clamping grooves 107 are opened on the baffle 102 at the upper and lower ends corresponding to one side of the half-coupling 101. During the docking and fitting of the half-coupling 101 and the baffle 102, the second clamping block 106 is driven to be inserted into the second clamping groove 107. The first clamping block 104 and the second clamping block 106 are staggered and their insertion ends are facing opposite directions. Therefore, during the positioning process, the stability of the connection on the other side can be further improved during the connection between the half-coupling 101 and the baffle 102.

[0039] It should also be noted that the plug-in ends of the first snap-in block 104 and the second snap-in block 106 are designed to be sloped, and the first slot 105 and the second slot 107 are opened to cooperate with each other, which can make the connection between the second snap-in block 106 and the second slot 107, and the first snap-in block 104 and the first slot 105 at the plug-in point more fitting, thereby increasing stability.

[0040] See also Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In this application, an annular positioning groove 108 and a sealing ring 109 are also provided, wherein an annular positioning groove 108 for inserting the sealing ring 109 is opened between the baffle 102 and the half coupling 101, so that after the sealing ring 109 is inserted into the annular positioning groove 108, the two are interference fit when plugged in, and when installed, it surrounds the outer ring of the first clamping block 104 and the second clamping block 106, thereby further improving the sealing of the connection.

[0041] A limiting ring 110 is also provided in the present application. When the baffle 102 is installed on the half coupling 101, the limiting ring 110 and the baffle 102 are in a connected state, so that the other end of the limiting ring 110 can be sleeved onto the outside of the baffle 102 and fit with its outer wall, thereby further limiting the connection surface between the baffle 102 and the half coupling 101.

[0042] See also Figure 2 、 Figure 5 、 Figure 6 and Figure 71, and the inner pressure ring 202 is positioned so that the inner pressure ring 2 is positioned in the groove 201 and the inner pressure ring 202 is positioned in the groove 201. The inner pressure ring 202 is positioned so that the inner pressure ring 2 is positioned in the groove 201 and the inner pressure ring 202 is positioned in the groove 201. The inner pressure ring 2 is designed to be a rubber material so that when the pin 103 connects the two sets of half couplings 101, the friction of the contact surface is increased, thereby improving the stability of the connection surface.
