[0002] The switch machine indicator rod is an important component for signal indication in the switch machine. It is mainly used to check the tightness of the turnout switch rail and indicate the position of the turnout. The switch machine indicator rod consists of a front indicator rod, a rear indicator rod, and two inspection blocks. The two rods are fixed together by tightening bolts and adjusting nuts. The front end of the front indicator rod has a connector for connecting with the indicator connecting rod of the turnout. The front end of the rear indicator rod has a long hole for connecting with the tightening bolt.

[0003] When the extended rod at the front end of the switch machine indicator rod is connected to the indicator connecting rod of the turnout, the extended rod at the front end of the indicator rod is prone to deformation and bending damage due to the long-term vibration of the railway caused by the train. In severe cases, it may even break. Since the traditional switch machine indicator rod is a one-piece structure, the entire front indicator rod needs to be replaced, which results in a waste of spare parts and materials. Utility Model Content

One end of the second protruding threaded rod on the connecting rod is threaded into another threaded rod groove on the extension rod. The extension rod is provided with a positioning component for positioning the first protruding threaded rod, the extension rod, and the connecting rod.

[0006] Preferably, the first protruding threaded rod at one end of the front indicator rod has a first hole, and the second protruding threaded rod at one end of the connecting rod has a second hole, wherein the diameters of the first hole and the second hole are the same.

[0007] Preferably, both ends of the extension rod have side holes, and the side holes at both ends of the extension rod are respectively connected to the threaded grooves at both ends.

[0008] Preferably, the outer surface of the extension rod has two annular grooves, and each of the two annular grooves on the outer surface of the extension rod has an external thread groove.

[0009] Preferably, the positioning component includes: Two pins are respectively inserted into the side holes at both ends of the extension rod, the first hole on the first protruding threaded rod, and the second hole on the second protruding threaded rod; Two internally threaded sleeves are respectively threaded into the externally threaded grooves in two annular grooves on the outer surface of the extension rod.

[0010] Preferably, both ends of the pin are arc-shaped, the thread on the inner wall of the internal threaded sleeve reaches half of its cylinder, and the inner wall of the internal threaded sleeve abuts against the arc-shaped ends of the pin.

[0011] Preferably, the connecting rod has three mounting holes.

[0012] This application configures the front indicator rod of the switch machine indicator rod as a separate assembly. After screwing the threaded groove of one end of the extension rod onto the first protruding threaded rod at one end of the front indicator rod, the second protruding threaded rod at one end of the connecting rod is screwed into the threaded groove at the other end of the extension rod. By adjusting the positioning component, the inner walls of the two internal threaded sleeves abut against the arc-shaped ends of the two pins, respectively, thereby achieving the connection and fixation of the first protruding threaded rod, the extension rod, and the connecting rod. When the connecting rod, the extension rod, or the front indicator rod is damaged, the corresponding parts can be replaced, thereby reducing the waste of materials for the entire rod body.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Due to the prolonged vibrations from trains, the extended rod at the front end of the indicator pole is prone to deformation and bending damage, which can even lead to breakage. Since the traditional front indicator pole of a switch machine is a single unit, the entire front indicator pole needs to be replaced, resulting in wasted materials. To address these issues, this embodiment discloses a switch machine indicator pole consisting of a front indicator pole 110 and a rear indicator pole 120. Figure 1 As shown; one end of the front indicator lever 110 has a first protruding threaded rod 1101, and the front indicator lever 110 further includes: as Figure 1 The extension rod 200 and connecting rod 300 are shown. like Figure 4 As shown, both ends of the extension rod 200 have threaded rod grooves 2001. The first protruding threaded rod 1101 at one end of the front indicator rod 110 is threadedly installed in the corresponding threaded rod groove 2001 on the extension rod 200. The first protruding threaded rod 1101 at one end of the front indicator rod 110 has a first hole 1102.

[0017] Continue as Figure 4 As shown, one end of the connecting rod 300 has a second protruding threaded rod 310. One end of the second protruding threaded rod 310 on the connecting rod 300 is threaded into another threaded rod groove 2001 on the extension rod 200. The second protruding threaded rod 310 at one end of the connecting rod 300 has a second hole 3101. The diameter of the first hole 1102 is the same as that of the second hole 3101.

[0018] Continue as Figure 4 As shown, the extension rod 200 is provided with a positioning component 400 for positioning the first protruding threaded rod 1101, the extension rod 200 and the connecting rod 300. For mounting the positioning assembly 400, both ends of the extension rod 200 have side holes 2002, which are connected to the threaded grooves 2001 at both ends of the extension rod 200. Simultaneously, the outer surface of the extension rod 200 has two annular grooves, each containing an external threaded groove 2003. The positioning assembly 400 includes two pins 410 and two internally threaded sleeves 420. The two pins 410 are respectively inserted into the extension rod 200. The pin 410 has arc-shaped structures at both ends. The two internal threaded sleeves 420 are respectively threaded into the external threaded grooves 2003 in the two annular grooves on the outer surface of the extension rod 200. The threads on the inner wall of the internal threaded sleeve 420 reach half of its cylinder body. The inner cylinder wall of the internal threaded sleeve 420 abuts against the arc-shaped ends of the pin 410.

[0019] After screwing the threaded groove 2001 at one end of the extension rod 200 onto the first protruding threaded rod 1101 at one end of the front indicator rod 110, screw the second protruding threaded rod 310 at one end of the connecting rod 300 into the threaded groove 2001 at the other end of the extension rod 200. At this time, the first hole 1102 on the first protruding threaded rod 1101 is connected to the side hole 2002 at one end of the extension rod 200; at the same time, the second hole 3101 on the second protruding threaded rod 310 is connected to the side hole 2002 at the other end of the extension rod 200. Then, insert the two pins 410 into the extension rod 200 respectively. The two side holes 2002 at both ends of the 00, the first hole 1102 on the first protruding threaded rod 1101, and the second hole 3101 on the second protruding threaded rod 310 are then screwed into the two internal threaded sleeves 420 respectively, so that the inner walls of the two internal threaded sleeves 420 abut against the arc-shaped ends of the two pins 410 respectively, thereby achieving the connection and fixation of the first protruding threaded rod 1101, the extension rod 200, and the connecting rod 300; when the connecting rod 300, the extension rod 200, or the front indicator rod 110 is damaged, the corresponding parts can be replaced, thereby reducing the waste of parts and materials of the entire rod body.

[0020] like Figure 1 As shown, the connecting rod 300 has three mounting holes 3001 for connecting with the indicator connecting rod of the turnout. The two are connected and installed by three sets of bolts and nuts. One end of the bolt passes through the mounting hole 3001 on the connecting rod 300 and the round hole of the indicator connecting rod of the turnout and is threaded with a nut for installation and connection.
