Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, and in particular to a brake pedal transmission device. Background Technology

[0002] The brake pedal of existing mobile C-arm X-ray machines is located directly above the wheels. However, during use, the operator pushes the equipment from behind, which results in a considerable distance between the operator and the brake pedal. When the operator needs to press the brake pedal, they must release their hand from the equipment and walk to the side of the equipment to press the brake pedal. This is not only very inconvenient for the operator, but also poses a risk of the equipment suddenly moving. Summary of the Invention

[0003] The purpose of this application is to provide a brake pedal transmission device.

[0004] To achieve the above objectives, this application provides the following technical solution: a brake pedal transmission device, including a brake pedal, a brake transmission rod, a brake pedal transmission rod, a transmission belt, a drive wheel, and a driven wheel. The brake transmission rod and the brake pedal transmission rod are both horizontally rotatably mounted on a chassis. The brake pedal is fixed to the end of the brake pedal transmission rod and is located on the side of the chassis. The drive wheel is fixedly connected to the middle of the brake pedal transmission rod, and the driven wheel is fixedly connected to the middle of the brake transmission rod. The transmission belt is sleeved between the drive wheel and the driven wheel. The middle of the brake pedal transmission rod also has a limiting block.

[0005] A wheel frame is also fixedly connected to the chassis, and an auxiliary wheel for tensioning the drive belt is rotatably mounted on the wheel frame.

[0006] Two fixed seats are fixedly connected to the chassis, and the brake pedal transmission rod is horizontally rotatably mounted on the fixed seats.

[0007] The drive wheel is fixed to the middle of the brake pedal transmission rod by a stop screw, and the driven wheel is fixed to the middle of the brake transmission rod by a limit screw.

[0008] In summary, the technical effects and advantages of this utility model are as follows: In this invention, the position of the brake pedal can be arbitrarily changed by adjusting the position of the fixed seat and the length of the transmission belt. The brake pedal can be moved to a position closer to the operator, making it convenient for the operator to operate. At the same time, it avoids the risk of the equipment suddenly moving when the operator releases the equipment and presses the brake pedal. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0012] like Figures 1-4As shown, this brake pedal transmission device includes a brake pedal 1, a brake transmission rod 3, a brake pedal transmission rod 11, a transmission belt 4, a drive pulley 9, and a driven pulley 5. Both the brake transmission rod 3 and the brake pedal transmission rod 11 are horizontally rotatably mounted on a chassis 12. Specifically, two fixed seats 10 are fixedly connected to the chassis 12, and the brake pedal transmission rod 11 is horizontally rotatably mounted on the fixed seats 10. Specifically, a steering caster 13 is rotatably mounted on the chassis 12. A brake structure 2 is provided between the steering caster 13 and the brake transmission rod 3. The brake structure 2 includes a locking element 201 and a hard ball 202. The hard ball 202 is fixed to the steering caster 13, and the locking element 201 is fixed to the brake transmission rod 3. The locking element 201 has a locking tongue that cooperates with the hard ball 202. The brake transmission rod... 3. After rotation, the locking element 201 abuts against the hard ball 202, or the locking element 201 disengages from the hard ball 202, thereby allowing the steering caster 13 to be in braking and unlocking states; the brake pedal 1 is fixed to the end of the brake pedal transmission rod 11, and the brake pedal 1 is located on the side of the chassis 12. The driving wheel 9 is fixed to the middle of the brake pedal transmission rod 11, and the driven wheel 5 is fixed to the middle of the brake transmission rod 3. Specifically, the driving wheel 9 is fixed to the middle of the brake pedal transmission rod 11 by the stop screw 8, and the driven wheel 5 is fixed to the middle of the brake transmission rod 3 by the limit screw 6; the transmission belt 4 is sleeved between the driving wheel 9 and the driven wheel 5. The middle of the brake pedal transmission rod 11 also has a limit block 7, which can limit the rotation of the brake pedal 1 within a certain range and prevent the brake pedal 1 from rotating without restriction.

[0013] A wheel frame 15 is also fixedly connected to the chassis 12, and an auxiliary wheel 14 for tensioning the drive belt 4 is rotatably mounted on the wheel frame 15.

[0014] In summary, the mounting base 10 is fixed to the chassis 12 with screws. The drive shaft of the brake pedal 1 passes through the hole in the mounting base 10 and can rotate within the hole. The limiting block 7 is fixed to the brake pedal drive rod 11 with screws and rotates together with the brake pedal drive rod 11. The brake pedal 1 is fixed to the brake pedal drive rod 11 with screws and rotates together with the brake pedal drive rod 11. The drive wheel 9 is fixed to the brake pedal drive rod 11 with the stop screw 8 and rotates together with the brake pedal drive rod 11. The brake drive rod 3 is connected to the brake structure 2 and controls the brake... The rotation of the transmission rod 3 controls the braking of the entire equipment. The driven wheel 5 is fixed to the brake transmission rod 3 by the limit screw 6 and rotates together with the brake transmission rod 3. The transmission belt 4 connects the driving wheel 9 and the driven wheel 5, so that the driving wheel 9 and the driven wheel 5 move synchronously. When the brake pedal 1 is pressed by foot, the brake pedal 1 drives the brake pedal transmission rod 11 to rotate, the brake pedal transmission rod 11 drives the driving wheel 9 to rotate, the driving wheel 9 drives the driven wheel 5 to rotate through the transmission belt 4, and the driven wheel 5 drives the brake transmission rod 3 to rotate, thereby controlling the braking and unlocking of the entire equipment by the brake structure 2.

[0015] In practice, the transmission belt 4 can be a chain belt or a synchronous belt.
