Description

Technical Field

[0001] The utility model belongs to the technical field of trams, and particularly relates to a modular signal machine connection structure. Background Art

[0002] Railway signal refers to a fixed signal on the railway that uses lights of different colors and numbers or arm positions of different colors and shapes to display command lines and shunting orders. It is an important part of the railway signal system. Railway signals appeared in the UK with the first train. The early signals were very simple. With the help of the development of the electronics industry, modern signals have automated the traffic control system, and train operations are also developing towards automatic driving and automatic control. On different sections of the road, signal machines are divided into single-light, double-light, three-light or even more-light signal machines according to the number of display meanings. Therefore, signal machines with different numbers of lights usually have one-piece lamp shells. When part of the lamp shell is damaged, the entire lamp shell needs to be replaced.

[0003] After searching, the Chinese patent for use information with the authorization announcement number CN219769901U discloses a signal installation structure, which improves the problem of inconvenient disassembly and assembly of multi-position display light signal machines, including a plurality of signal lights, the signal lights including a shell and a lamp body and a lamp holder installed in the shell and electrically connected to each other, a plurality of wires connected to the lamp holder, a first terminal seat provided on the bottom wall of the shell, the wires are integrated and connected to the first terminal seat of the shell, a second terminal seat provided on the top wall of the shell and electrically connected to the first lamp holder or the first terminal seat, the first terminal seat being used for plugging and matching with the second terminal seat of the adjacent signal light, a locking mechanism capable of locking two adjacent signal machine shells is provided on the side wall of the shell, when the two signal lights are installed correspondingly, the second terminal seat of the lower signal light is plugged into the first terminal seat of the upper signal light to exchange signals, and the two shells are directly locked by the locking mechanism of the outer wall, without the need for disassembly and assembly using tools;

[0004] In addition, when installing the lamp housing, slide the second cover open, install the two signal lamps correspondingly, plug the second terminal seat of the lower signal lamp with the first terminal seat of the upper signal lamp together to exchange signals, then open the handle and turn it to slide the lock buckle upward, and then turn the lock sleeve by the handle to make the lock buckle abut against the hook piece, the elastic member can drive the lock buckle and the hook piece to be tightly connected together, and a locking mechanism is set under the lower cover of the first cover to stably connect the two signal lamps; when disassembling, open the first cover, turn the handle to slide the lock buckle upward, and then turn the lock sleeve to separate the lock buckle from the hook piece, and then you can directly pull out the upper signal lamp as a whole, without the need for tools for disassembly and assembly, which is more convenient for workers to operate. In addition, the buffer layer can reduce the vibration transmission caused by the passing of the train, making the signal machine structure more stable.

[0005] It can be seen from the prior art that in the prior art, the connection between the two lamp housings is directly locked by a locking mechanism of the two shells through the outer wall. In addition, when installing or disassembling the two lamp housings, there are more steps for installation or disassembly, and the installation and disassembly methods are also more complicated. Most of the parts of the locking mechanism are non-standard parts with high processing costs, and the sealing between the lamp housings is poor. Therefore, this shortcoming needs to be improved urgently. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 6As shown, a modular signal connection structure includes a plurality of lamp housings 1, at least two mutually symmetrical connection structures 5 are arranged between two adjacent lamp housings 1, and the connection structures 5 each include a connection plate 51 and a fixing plate 54. In this embodiment, the connection structure 5 has two connection plates 51, and the connection plate 51 and the fixing plate 54 are respectively arranged at the upper and lower ends of the side wall of the lamp housing 1. The connection plates 51 each have a through hole 511, and the two through holes 511 are arranged coaxially, and a connecting shaft 52 is installed in the two through holes 511, and a connecting rod 53 is movably connected to the outer periphery of the connecting shaft 52. The connecting rod 53 is located between the two connecting plates 51. The connecting rod 53 has a connecting portion 531 and a matching portion 533. The connecting portion 531 has a first waist-shaped hole 532. The connecting shaft 52 is slidably arranged in the first waist-shaped hole 532. The fixed plate 54 has a connecting hole 541 for the matching portion 533 to pass through. The matching portion 533 has a thread on its outer periphery. The matching portion 533 is threadedly connected to a nut 55 on its outer periphery. When the matching portion 533 is arranged in the connecting hole 541 and is threadedly matched with the nut 55, the nut 55 is arranged on the side of the fixed plate 54 away from the connecting plate 51.

[0024] In addition, when one end of the first waist-shaped hole 532 close to the matching part 533 contacts the connecting shaft 52, and the matching part 533 is in a coaxial state with the connecting hole 541, the distance between the end of the matching part 533 and the end surface of the fixing plate 54 close to the connecting plate 51 is greater than or equal to zero, so that the connecting rod 53 can be inserted into the connecting hole 541 in the fixing plate 54.

[0025] In addition, a sealing gasket 3 is sealed between two adjacent lamp housings 1. The cross section of the sealing gasket 3 is in an I-shape. The ends of the two adjacent lamp housings 1 are sealed in the groove of the sealing gasket 3, so that the sealing between the lamp housings 1 is stronger.

[0026] A top cover 2 is fixedly installed on the upper end of the lamp housing 1 at the top. The top cover 2 is processed by profile breaking and designed with external drainage to ensure that there is no water accumulation on the top cover and the inside of the signal machine remains dry.

[0027] The lower end of the lamp housing 1 at the lowest end is fixedly connected to the base 4 by bolts, and the base 4 has at least one second waist-shaped hole 41 and a third waist-shaped hole 42. The third waist-shaped hole 42 is an arc-shaped waist-shaped hole, and the second waist-shaped hole 41 extends radially along the third waist-shaped hole 42. Bolts are installed in the second waist-shaped hole 41 and the third waist-shaped hole 42, and the base 4 is fixed to the mounting bracket at the railway site by bolts.

[0028] It should be noted that each lamp housing 1 has the same structure, so the efficiency is higher and the cost is lower when processing the lamp housing 1 , and the cost of replacing, installing and repairing the lamp housing 1 when it is damaged is lower.

[0029] When connecting two lamp housings 1, firstly, a sealing gasket 3 is placed on the upper end of the lamp housing 1, so that the groove in the sealing gasket 3 is inserted into the end of the lamp housing 1, and then the other lamp housing 1 is installed in the groove at the other end of the sealing gasket 3. Furthermore, the connecting rod 53 is rotated around the axis direction of the connecting shaft 52, so that the matching portion 533 of the connecting rod 53 enters the connecting hole 541, and the matching portion 533 of the connecting rod 53 penetrates the fixing plate 54, and then a nut 55 is installed on the outer periphery of the matching portion 533. By rotating the nut 55, since the connecting portion 533 cannot rotate around the axis of the nut 55, and the matching portion 533 is 33 is threadedly connected with the nut 55, so rotating the nut 55 can drive the connecting rod 53 to move toward the side close to the fixed plate 54. When the connecting shaft 52 abuts against the end of the first waist-shaped hole 532 away from the matching portion 533, the nut 55 continues to be rotated. At this time, the connecting rod 53 drives the connecting plate 51 to move toward the side close to the fixed plate 54, thereby reducing the distance between the two adjacent lamp housings 1, and the two lamp housings 1 squeeze the sealing gasket 3 to deform, thereby achieving a sealed fit between the sealing gasket 3 and the two lamp housings 1, thereby achieving fixed installation of the two lamp housings 1.

[0030] Therefore, the above installation method is more convenient. It only needs to install the sealing gasket 3 between the two lamp housings 1, and then insert the matching part 533 of the connecting rod 53 into the connecting hole 541, and then connect the nut 55 with the matching part 533 and rotate the nut 55 to achieve installation, and the sealing between the lamp housings 1 is stronger.
