The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0013] See Figures 1 to 3 The first embodiment of this utility model provides a track inspection instrument bracket push rod that can be detachably installed on the track inspection instrument. It includes a connecting component 4, a support rod 3, a push handle component 2, and a bracket component 1 in sequence. The connecting component 4 is connected to the track inspection instrument, and the laptop computer is installed on the bracket component 1. By pushing the push handle component 2, the entire device slides on the track to measure track data.

[0014] The bracket assembly 1 is rotatably connected to one end of the push handle assembly 2. It includes a tray 11, a fixed side plate 12, and an adjustable side plate assembly 13. The fixed side plate 12 and the adjustable side plate assembly 13 are respectively disposed at both ends of the tray 11 and fixedly connected to it, forming a cavity in the middle for securing the laptop. Specifically, the adjustable side plate assembly 13 includes a support plate 131 fixedly connected to the tray 11, an adjusting block 132 disposed on the upper end of the support plate 131 and slidably connected to it, and a locking screw 133 disposed on the lower end of the support plate 131 for locking the relative sliding of the support plate 131 and the adjusting block 132. Further, the fixed side plate 12 and the adjusting block 132 both extend outward from the side away from the tray 11 to form a first hook portion 1 for clamping the laptop. The first hook portion 121 and the second hook portion 137 are arranged facing each other. The first hook portion 121 of the fixed side plate 12 and the second hook portion 137 of the adjusting block are pressed against both ends of the laptop, limiting the laptop in the accommodating cavity. It should be noted that the adjusting block 132 is located in the middle of the support plate 131 and can slide back and forth along the support plate 131 toward the tray 11 to adjust the size of the accommodating cavity. When fixing the laptop, after the laptop is placed in the accommodating cavity, the adjusting block 132 is slidably adjusted so that the laptop is clamped between the fixed side plate 12 and the adjusting block 132 of the adjustable side plate assembly 13. Then, the adjusting block 132 is locked by rotating the locking screw 133, so that the second hook portion 137 presses the laptop, thereby fixing the laptop more stably.

[0015] Furthermore, in this embodiment, a slot 134 is provided in the middle of the support plate 131, and the slot 134 is provided through the support plate 131. The adjusting block 132 extends outward on one side to form a boss, which is adapted to the slot 134. For example, the slot 134 is a rectangular structure, while the boss can be a cuboid structure; the slot 134 is an oblong hole structure, while the boss is a cylindrical structure. This allows the adjusting block 132 to slide within the slot 134 and is less likely to detach from the sliding connection with the support plate 131. In addition, in order to make the adjusting block 132 more stable in the sliding direction, one side of the support plate 131 is recessed downward to form a groove, while the adjusting block 132 extends outward to form a slider. Through the cooperation of the groove and the slider, the adjusting block 132 slides more smoothly on one side of the support plate 131.

[0016] Furthermore, the tray 11 has an upper surface and a lower surface that are arranged opposite to each other. The tray 11 assembly also includes a mounting plate 14 with one end fixedly connected to the lower surface. The other end of the mounting plate 14 is connected to the push handle assembly 2. Specifically, a mounting plate 14 is installed on one side of the lower surface of the tray 11. The mounting plate 14 is L-shaped. One end of the mounting plate 14 is attached to the lower surface of the tray 11 and fixedly connected to the tray 11 by bolts, while the other end is rotatably connected to the push handle assembly 2. In this embodiment, the mounting plate 14 has two pieces that are arranged opposite to each other and are located on both sides of the support rod 3 and connected to the push handle assembly 2.

[0017] See Figure 3 The push handle assembly 2 includes a sleeve rod 21, a push handle 22, and a positioning pin assembly 23. In this embodiment, part of the sleeve rod 21 is sleeved on the end of the support rod 3 away from the connecting assembly 4, while the other end is flat on both sides. The push handle 22 extends through both flat surfaces. Furthermore, the push handle 22 includes a connecting rod 221 extending through both sides of the sleeve rod 21, and two grips at both ends of the connecting rod 221. Specifically, the connecting rod 221 extends through both sides of the sleeve rod 21 and is fixedly connected to the sleeve rod 21 by screws to prevent axial rotation of the connecting rod 221. Grips are provided at both ends of the connecting rod 221. It is understood that the two grips are perpendicular to the sleeve rod 21, and the connection direction of the two grips is perpendicular to the installation direction of the bracket assembly 1. This allows the user to observe the data measured by the laptop while holding the grips and pushing the entire device.

[0018] A positioning pin assembly 23 is also provided on the sleeve rod 21. The positioning pin assembly 23 is located at the end of the push handle 22 away from the support rod 3, that is, at the upper part of the sleeve rod 21. In this embodiment, the sleeve rod 21 has through holes through both sides of the plane. The positioning pin assembly 23 includes two positioning pins 231 set in the through holes and a spring 232 set in the through holes between the two positioning pins 231. The two positioning pins 231 are arranged facing each other and can slide in the through holes. The spring 232 is used to push the two positioning pins 231 to extend out of the through holes. A mounting plate 14 is sleeved on the connecting rod 221. The mounting plate 14 can rotate along the axial direction of the connecting rod 221. The connecting rod 221 is located between the sleeve 21 and the handle. Notably, a pad 227 is provided between the mounting plate 14 and the sleeve 21 to prevent direct friction between the mounting plate 14 and the sleeve 21 during rotation. The mounting plate 14 has multiple positioning holes 141 that are adapted to positioning pins 231 to lock the rotation of the mounting plate 14 around the connecting rod 221. Specifically, the multiple positioning holes 141 are distributed along the rotation trajectory of the positioning pins 231. It can be understood that the angle adjustment of the bracket assembly 1 is achieved through the cooperation of the positioning holes 141 and the positioning pins 231. Those skilled in the art can set the number and spacing of the positioning holes 141 according to the actual situation.

[0019] In some embodiments, the handle includes a connecting rod 222 with one end connected to the connecting rod 221, and a handle rotatably connected to the connecting rod 222. The handle includes a handle body 224 and a fork 223 with one end rotatably connected to the handle body 224. The other end of the fork 223 is connected to the connecting rod 222. A locking pin 225 is slidably disposed within the handle body 224. One end of the locking pin 225 passes through the fork 223. One side of the connecting rod 222 is provided with a fitting that is adapted to the locking pin 225 for engaging the handle. The handle body 224 is locked in the working position or the storage position by multiple pin holes 226. It should be noted that when the handle body 224 is in the working position, the handle body 224 is set perpendicular to the sleeve rod 21, while when the handle body 224 is rotated to the storage position, it is set parallel to the sleeve rod 21. It can be understood that there are three pin holes 226. One is set at the end of the connecting rod 222 away from the connecting rod 221, and the locking pin 225 is inserted into the pin hole 226 to make the connecting rod 222 and the handle body 224 be on the same straight line. The other two are set symmetrically on both sides of the connecting rod 222.

[0020] In summary, the track inspection instrument bracket push rod in the above embodiments of this utility model has an adjustable side plate assembly at one end of the bracket assembly's support plate. The size of the accommodating cavity can be adjusted by the sliding setting of the adjusting block within the support plate, facilitating the installation and fixation of the laptop. Under the action of the locking screw at the lower end of the support plate, the sliding of the support plate and the adjusting block is locked, making the laptop more stable under the clamping and holding of the fixed side plate and the adjustable side plate assembly. Furthermore, the bracket assembly and the push rod assembly are locked at a specific angle through the cooperation of the positioning holes and positioning pins on the mounting plate, ensuring the stability of the laptop fixed at the top during operation and preventing wobbling.
