Description

Technical Field

[0001] The utility model belongs to the technical field of manufacturing parts for electrified railway contact network, and specifically relates to a novel wrist-arm connector. Background Art

[0002] The wrist arm connector is an important connector between the wrist arm support structure and the positioning device. The existing wrist arm connector is easy to rotate around the wrist arm tube during installation, and it is difficult to ensure that the vertical plane of the wrist arm connector coincides with the vertical planes of the flat, oblique wrist arm tube and the positioning tube, resulting in a large workload and low installation efficiency on site. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the utility model provides a novel wrist-arm connector.

[0004] The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0005] A novel wrist-arm connector comprises a half hoop body and a U bolt connected to the half hoop body. A positioning protrusion is provided in the middle of the arc surface of the half hoop body along the axial direction.

[0006] Furthermore, the arc section of the U bolt has a flat structure.

[0007] Furthermore, the U bolt is a double-headed structure.

[0008] Furthermore, the positioning protrusion is a rectangular structure.

[0009] Furthermore, the end of the half clamp body away from the arc surface has two ears.

[0010] Beneficial effects of the utility model:

[0011] 1. The utility model is provided with a positioning protrusion, which can cooperate with the flat or oblique wrist arm tube or positioning tube with a groove during installation, accurately position, and prevent deflection, thereby ensuring that the vertical plane of the wrist arm connector coincides with the vertical plane of the flat or oblique wrist arm tube and the positioning tube, thereby improving the installation efficiency.

[0012] 2. The utility model is connected to the half clamp body by a flat double-headed U bolt, which reduces the number of parts and components, and is simple, convenient and quick to install.

[0013] 3. The arc surface of the U bolt of the utility model adopts a flat structure, which increases the contact surface with the wrist arm, improves the clamping force, and prevents axial movement.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Example 1: See Figure 1-2 The novel wrist-arm connector comprises a half-hoop body 1 and a U bolt 2. The half-hoop body 1 has a rectangular positioning protrusion 1-2 in the middle of the arc surface along the axial direction, and has two ears 1-1 at the end away from the arc surface; the U bolt 2 is a double-headed structure and the arc section is a flat structure.

[0021] When the utility model is used in conjunction with the wrist arm tube 4, a rectangular groove 4-1 is axially arranged on the wrist arm tube 4, and the width of the rectangular groove 4-1 is consistent with that of the rectangular positioning protrusion 1-2, and the depth of the rectangular groove 4-1 is greater than the height of the rectangular positioning protrusion 1-2. The wrist arm tube 4 includes but is not limited to flat and oblique wrist arm tubes and positioning tubes, and also includes other pipes on the wrist arm support positioning device. The installation method of Example 1 is the same as that of Example 2.

[0022] Example 2: See Figure 3 The new wrist-arm connector includes a half-hoop body 1 and a U bolt 2. The half-hoop body 1 has a rectangular positioning protrusion 1-2 in the middle of the arc surface along the axial direction, and has a double ear 1-1 at the end away from the arc surface; the U bolt 2 is a single-head structure and the arc section is a flat structure. During installation, first snap the half-hoop body 1 onto the wrist-arm tube 4, and insert the rectangular positioning protrusion 1-2 into the rectangular groove 4-1 to ensure that the plumb plane of the half-hoop body 1 coincides with the plumb plane of the wrist-arm tube 4, and then insert the single-head U bolt 2 into the fixing hole on the half-hoop body 1, install the fastening nut 5 and apply torque. The double ears 1-1 are installed with pins 3, and other parts of the contact network are connected through the pins 3.

[0023] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
