AI Technical Summary
Traditional hotel food carts have fixed handle heights that cannot be adjusted, resulting in poor comfort for waiters of different heights while pushing the carts, especially for taller waiters who are prone to lower back fatigue.
A trolley structure with an adjustable handle height was designed. The handle height can be adjusted by combining a guide sleeve, a slider, a connecting rod, a drive block, a transmission block and a spring. The cooperation of the inclined plane and the slide groove drives the locking block to disengage and insert in the slot, so as to achieve flexible adjustment of the handle.
The design accommodates staff of different heights, improving the comfort of using the trolley, reducing lower back fatigue, and enhancing the user experience.

[0031] Reference Figure 1-5 A food trolley 100 for hotels includes: a trolley body 101, a guide sleeve 102, a handle 103, and an adjusting member for adjusting the height of the handle 103. The guide sleeve 102 is fixedly connected to the trolley body 101. The handle 103 is inserted into the guide sleeve 102.
[0032] An adjusting component is used to adjust the height of the handle 103. The adjusting component includes: a first slider 104, a connecting rod 105, a driving block 106, a first spring 107, a transmission block 108, a second spring 109, a locking block 110, and a push plate 112. The first slider 104 is vertically slidably connected to the guide sleeve 102. Specifically, the guide sleeve 102 includes a guide hole 102a, the first slider 104 is located within the guide hole 102a, and can move axially along the guide hole 102a. The handle 103 is partially located within the guide hole 102a and can move axially along the guide hole 102a. The connecting rod 105 is fixedly connected to the first slider 104.
[0033] The drive block 106 is fixedly connected to the connecting rod 105. The two ends of the first spring 107 are fixedly connected to the guide sleeve 102 and the first slider 104, respectively. The first spring 107 is located at the lower end of the first slider 104, and the connecting rod 105 is located at the upper end of the first slider 104. The transmission block 108 is radially slidably connected to the guide sleeve 102. Specifically, the guide sleeve 102 is provided with a first groove 102b extending radially along the guide sleeve 102, and the transmission block 108 moves along the first groove 102b.
[0034] A locking block 110 is located at one end of the transmission block 108, and a second spring 109 is located at the other end of the transmission block 108. The two ends of the second spring 109 are fixedly connected to the guide sleeve 102 and the transmission block 108, respectively. The locking block 110 is fixedly connected to the transmission block 108. The push plate 112 is fixedly connected to the first slider 104. The handle 103 includes a slot 103a, and the locking block 110 engages with the slot 103a to limit the movement of the handle 103. Multiple slots 103a are provided, equidistantly distributed along the axial direction of the guide sleeve 102.
[0035] The drive block 106 includes a first inclined surface 106a, and the transmission block 108 includes a second inclined surface 108a. The drive block 106 drives the transmission block 108 to move through the first inclined surface 106a and the second inclined surface 108a. The guide sleeve 102 includes a clearance groove 102c, through which the push plate 112 passes, and is spaced apart from the push plate 112. Pushing the push plate 112 causes the connecting rod 105 to move, which in turn moves the drive block 106. The transmission block 108 moves along the first slide groove 102b. Thus, the drive block 106 moves along the first inclined plane 106a and the second inclined plane 108a, causing the transmission block 108 to move along the first slide groove 102b. The movement of the transmission block 108 causes the locking block 110 to move, disengaging it from the slot 103a. Then, the handle 103 is adjusted to a suitable height. After releasing the push plate 112, the first slider 104 is reset by the action of the first spring 107, and the transmission block 108 is reset by the action of the second spring 109. This allows the locking block 110 to re-insert into the slot 103a, thus completing the height adjustment of the handle 103, making it suitable for people of different heights.
[0036] Workflow: When the height of handle 103 needs to be adjusted, push plate 112 is pushed. Push plate 112 moves, causing connecting rod 105 to move. Connecting rod 105 moves, causing drive block 106 to move. Transmission block 108 moves along the first slide groove 102b. Therefore, drive block 106 moves along the first slide groove 102b via the first inclined surface 106a and the second inclined surface 108a. Transmission block 108 moves, causing locking block 110 to move, disengaging locking block 110 from slot 103a. Then, handle 103 is adjusted to the appropriate height. Then, push plate 112 is released. Under the action of first spring 107, first slider 104 is reset. Under the action of second spring 109, transmission block 108 is reset, thus locking block 110 is reinserted into slot 103a, thereby completing the height adjustment of handle 103, making it suitable for people of different heights. When the locking block 110 is not inserted into the slot 103a, the position of the handle 103 can be slightly adjusted up and down to insert the locking block 110 into the slot 103a, thus completing the height adjustment of the handle 103. The adjustment is convenient and suitable for waiters of different heights, increasing the comfort of the waiters.
