The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0025] Embodiment 1

[0026] See also Figures 1 to 6The utility model preferably provides a technical solution: an adjustable guardrail for a sightseeing car, comprising a first guard arm 1, which is installed on both sides of the sightseeing car seat; a second guard arm 2, which is movably sleeved on the end of the first guard arm 1, and the second guard arm 2 cooperates with the first guard arm 1 to limit tourists from falling from both sides of the sightseeing car operation. The first guard arm 1 and the second guard arm 2 are provided with a positioning mechanism for limiting the movement of the second guard arm 2 relative to the first guard arm 1, wherein the top and bottom of the second guard arm 2 away from the first guard arm 1 are both provided with a third guard arm 3, and the end of the first guard arm 1 away from the second guard arm 2 is fixed with a shaft sleeve 4, and a shaft block 5 is rotatably connected to the shaft sleeve 4, and a pillow block 6 for horizontally limiting the first guard arm 1 is fixed at the bottom of the shaft block 5, Through this structural manner, the shaft blocks 5 are fixed at both ends of the sightseeing car seat backrest. When the first guard arm 1 drives the shaft sleeve 4 to rotate upward to a vertical position, tourists can get on and off the car smoothly from both ends of the seat. When the first guard arm 1 rotates downward and the pillow block 6 horizontally supports the first guard arm 1, the first guard arm 1 and the second guard arm 2 can form protection at both ends of the sightseeing car seat to prevent tourists from falling and causing safety accidents. In addition, the second guard arm 2 is extended and retracted at the end of the first guard arm 1, and the second guard arm 2 and the first guard arm 1 are relatively positioned in cooperation with the positioning mechanism. In addition, the third guard arm 3 is arranged at the end of the second guard arm 2, which can expand the protection area of ​​the guardrail at both ends of the sightseeing car seat and improve the safety of tourists riding the sightseeing car.

[0027] In this embodiment, the positioning mechanism includes a guide groove 7 and a positioning groove 8 opened on the first guard arm 1 and a positioning shaft 10 fixed to the inner end portion of the second guard arm 2. The guide groove 7 is distributed along the length direction of the first guard arm 1, and the positioning shaft 10 is penetrated in the guide groove 7 and can move along the guide groove 7. There are multiple positioning grooves 8, and multiple positioning grooves 8 are located above the guide groove 7 and are connected to the guide groove 7. The positioning shaft 10 is adapted to fit with the positioning groove 8. An adaptation groove 9 is opened on the top of the second guard arm 2 facing one end of the first guard arm 1, and a through arrangement is set at the bottom of the second guard arm 2. Through this structural method, the second guard arm 2 is lifted up away from one end of the first guard arm 1, and the positioning shaft 10 can slide along the guide groove 7. At this time, the second guard arm 2 can be telescopically expanded or reduced in the protection area. The second guard arm 2 is pressed down away from one end of the first guard arm 1, and the positioning shaft 10 is embedded in the corresponding positioning groove 8. The second guard arm 2 and the first guard arm 1 are relatively positioned, which can provide a good protection effect. The result is simple and convenient for tourists to operate.

[0028] Furthermore, the positioning groove 8 is tilted toward one side of the second guard arm 2 , which can delay the positioning shaft 10 from escaping from the positioning groove 8 .

[0029] Embodiment 2

[0030] The difference from the first embodiment is that the positioning mechanism includes a plurality of positioning holes 11 provided on the first guard arm 1 and a spring pin 12 provided on the second guard arm 2 and plugged with the positioning holes 11. The spring pin 12 includes a fixing tube 13 fixed on the side wall of the second guard arm 2 facing the first guard arm 1, a connecting rod 16 movably inserted in the fixing tube 13, a baffle 14 fixed to the end of the connecting rod 16 facing the second guard arm 2, a positioning pin 15 provided on the side of the baffle 14 facing the second guard arm 2, and a compression spring provided between the baffle 14 and the inner end wall of the fixing tube 13. 17, the positioning pin 15 passes through the side wall of the second guard arm 2 and is plugged into the positioning hole 11, the connecting rod 16 passes through the fixing tube 13 away from one end face of the second guard arm 2 and is fixed with a handle 18, and the positioning pin 15 is driven to disengage from the positioning hole 11 by pulling the handle 18. At this time, the second guard arm 2 can be telescopically expanded or reduced in the protection area. After releasing the handle 18, the elastic force of the compression spring 17 pushes the baffle 14 to make the positioning pin 15 plugged into the positioning hole 11 on the positioning hole 11. At this time, the second guard arm 2 and the first guard arm 1 can be relatively positioned, which is used for effective protection at both ends of the sightseeing car seat.

[0031] When in use, the shaft blocks 5 are fixed at both ends of the sightseeing car seat backrest. When the first guard arm 1 drives the shaft sleeve 4 to rotate upward to a vertical position, tourists can get on and off the car smoothly from both ends of the seat. When the first guard arm 1 rotates downward and the pillow block 6 horizontally supports the first guard arm 1, the first guard arm 1 and the second guard arm 2 can form protection at both ends of the sightseeing car seat to prevent tourists from falling and causing safety accidents. Furthermore, the second guard arm 2 is extended and retracted at the end of the first guard arm 1, and the second guard arm 2 and the first guard arm 1 are relatively positioned in cooperation with the positioning mechanism. In addition, the third guard arm 3 is arranged at the end of the second guard arm 2, which can expand the protection area of ​​the guardrail at both ends of the sightseeing car seat and improve the safety of tourists riding the sightseeing car.
