Description
Technical Field
[0001] This utility model relates to the field of luggage technology, specifically to a luggage handle structure. Background Technology
[0002] With societal development, people are increasingly traveling for leisure and business. Suitcases, as a tool for carrying belongings when traveling, are becoming more and more widely used due to their convenience and ease of use.
[0003] A typical suitcase generally includes a suitcase body, wheels fixed to the bottom of the suitcase body, and a pull rod fixed to the side of the suitcase body. The pull rod has a switch block that can be pressed down. Corresponding to the switch block, two sliding rods are also installed inside the pull rod. When the switch block is pressed down, the sliding rods can move to the sides. The sliding rods can then drive the top rod to move down through transmission. The movement of the top rod can release the fixed state of the pull rod, thereby indirectly causing the pull rod to be pulled out of the suitcase or pressed into the suitcase.
[0004] While the above method can meet the normal use conditions of the suitcase, if the user does not press the middle position of the switch block precisely, that is, press the end position of the switch block so that one end of the switch block moves down, the switch block can only indirectly release one of the push rods from moving down. In other words, the entire pull rod is still in a fixed state and cannot move up and down on the suitcase. Utility Model Content
[0005] In view of this, the present invention provides a luggage pull rod structure, which allows the pull rod to be pulled up and down on the luggage even when the end of the switch block is pressed.
[0006] To solve the above-mentioned technical problems, this utility model provides a luggage handle structure, including a handle disposed between the ends of two handles and a switch block that slides up and down inside the handle. The handle has a cavity, and when the switch block moves downward, the bottom of the switch block can move into the cavity. Two sliding rods are slidably disposed in the cavity corresponding to the switch block. The two sliding rods are located on the same axis and on both sides of the switch block. The downward movement of the switch block can cause the sliding rods to move in opposite directions within the cavity. The inner ends of the two sliding rods are provided with connecting rods, and a transmission component is connected between the two connecting rods. When one sliding rod moves inward, it can drive the other sliding rod to move inward synchronously through the transmission component. When one sliding rod moves outward, it can drive the other sliding rod to move outward synchronously through the transmission component. That is, the two sliding rods can move synchronously relative to each other or in opposite directions through the transmission component.
[0007] The connecting rod is formed by extending forward from the inner end sidewall of the slide rod, and the connecting rod and the slide rod have an L-shaped structure.
[0008] The handle includes a housing, and the transmission assembly includes a rotating rod rotatably mounted on the housing. The rotating rod is rotatable on the housing and is located between the inner ends of two sliding rods in the cavity. Two connecting rods are located on both sides of the rotating rod. A gear is provided on the outer side of the rotating rod. The rotating rod and the gear can rotate together. A rack is provided on the inner wall of the connecting rod corresponding to the gear. The teeth on the two racks mesh with the teeth on the gear, and the racks can drive the gear to rotate.
[0009] The switch block has abutment blocks at both ends of its bottom. The switch block can drive the abutment blocks to move down. Corresponding to the abutment blocks, there are extension blocks at the ends of the two connecting rods. The connecting rods and extension blocks form an L-shaped structure. The outer end face of the extension block on one of the slide rods and the inner end face of the other slide rod are both located directly below the abutment block. When either abutment block moves down, the two slide rods can move synchronously in opposite directions.
[0010] There is a V-shaped storage groove between one of the slide bars and the extension block on the other slide bar. The storage groove is vertically aligned with the lower end of the contact block. The opening width of the storage groove is greater than the width of the lower end of the contact block. When the contact block moves down, the end of the contact block can move into the storage groove. That is, the movement of the contact block can indirectly cause one of the slide bars and the extension block on the other slide bar to move in opposite directions.
[0011] The inner end faces of both slide rods are provided with a second inclined surface, and the outer end face of the extension block on each slide rod is provided with a third inclined surface. The second inclined surface and the third inclined surface can form a V-shaped storage groove.
[0012] The bottom of the abutment block is symmetrically provided with a first inclined surface. When the abutment block moves downward, the two first inclined surfaces can abut against the second and third inclined surfaces respectively. The lower part of the abutment block is also a V-shaped structure.
[0013] The connecting rods are located on the sides of the two abutting blocks, and the connecting rods will not abut against the abutting blocks when they slide. The connecting rods and the extension blocks form an L-shaped structure, and the two sets of connecting rods and extension blocks are axially distributed on both sides of the two abutting blocks.
[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0015] 1. The transmission component enables the sliding of one slide rod to indirectly drive the other slide rod to slide, so that even when the end of the switch block is pressed, the pull rod can still be pulled up and down on the suitcase.
[0016] 2. The transmission assembly enables the two slide rods to slide synchronously, and the design of the extension block, the first inclined surface, the second inclined surface, and the third inclined surface makes the sliding cooperation between the two slide rods more stable.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-7 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0030] like Figure 1 , 3As shown in Figures 4, 5, 6, and 7: The system includes a handle 100 positioned between the ends of two levers and a switch block 200 that slides vertically within the handle 100. Moving the switch block 200 downwards releases the lever's limiting position. The handle 100 contains a chamber 102. When the switch block 200 moves downwards, its end moves into the chamber 102. Two sliding rods 300 are slidably positioned within the chamber 102 corresponding to the switch block 200. The two sliding rods 300 are located on the same axis and on opposite sides of the switch block 200. The downward movement allows the slide rods 300 to move in opposite directions within the chamber 102. Each of the two slide rods 300 has a connecting rod 301 at its inner end, and a transmission assembly 400 connects the two connecting rods 301. When one slide rod 300 moves inward, it can drive the other slide to move inward synchronously through the transmission assembly 400. When one slide rod 300 moves outward, it can drive the other slide to move outward synchronously through the transmission assembly 400. That is, the two slide rods 300 can move synchronously relative to each other or in opposite directions through the transmission assembly 400.
[0031] When it is necessary to control the pull rod to move up and down on the suitcase, press down the switch block 200 on the handle 100. When one end of the switch block 200 is pressed, the downward movement of one end of the switch block 200 can press one of the slide rods 300 to move to the side. This slide rod 300 can then indirectly drive the other slide rod 300 to move outward through the connecting rod 301 and the transmission component 400. Even when the end of the switch block 200 is pressed, the two slide rods 300 can still move synchronously. This allows the slide rods 300 to indirectly drive the two push rods to move down, thereby canceling the limit state of the pull rod.
[0032] like Figure 3 , 4 As shown in 5, 6, and 7,
[0033] The connecting rod 301 is formed by extending forward from the inner end sidewall of the slide rod 300, that is, the connecting rod 301 and the slide rod 300 form an L-shaped structure.
[0034] like Figure 3 , 4 As shown in 5, 6, and 7,
[0035] The handle 100 includes a housing 101, and the transmission assembly 400 includes a rotating rod 401 rotatably mounted on the housing 101. The rotating rod 401 is vertically mounted on the housing 101 and can rotate on the housing 101. The rotating rod 401 is located between the inner ends of two sliding rods 300 within the chamber 102, and two connecting rods 301 are located on both sides of the rotating rod 401. A gear 402 is provided on the outer side of the rotating rod 401, and the rotating rod 401 can drive the gear 402 to rotate between the inner ends of the two sliding rods 300. The gear 402 is located on the inner wall of the connecting rod 301. The device is equipped with racks 403, and the teeth on the two racks 403 mesh with the teeth on the gears 402. That is, when one of the slide rods 300 slides, it can drive the connecting rod 301 connected to it to slide. The connecting rod 301 can drive the racks 403 to slide. The racks 403 can then drive the gears 402 to rotate the rod 401 on the housing 101. The gears 402 can then drive the other connecting rod 301 to slide. In this way, the two slide rods 300 can move synchronously relative to each other or move in opposite directions through the transmission assembly 400.
[0036] Meanwhile, the transmission mechanism can also be set in a rotating rod 401 rotatably mounted on the housing 101. The rotating rod 401 is vertically mounted on the housing 101 and can rotate on the housing 101. The rotating rod 401 is located between the inner ends of the two sliding rods 300 in the chamber 102, and the two connecting rods 301 are located on both sides of the rotating rod 401. Two telescopic rods are provided on the side wall of the rotating rod 401. The two telescopic rods are located on the same axis. The ends of the telescopic rods are connected to the corresponding connecting rods 301 by hinges. Thus, when one of the sliding rods 300 slides, it can drive the connecting rod 301 connected to it to slide. The connecting rod 301 can drive the telescopic rod connected to it to rotate and extend. The telescopic rod can drive the rotating rod 401 to rotate. The rotating rod 401 can drive the other telescopic rod to rotate and extend. In this way, it can indirectly drive the other sliding rod 300 and the connecting rod 301 to slide. Thus, the two sliding rods 300 can move synchronously relative to each other or move in opposite directions through the transmission component 400.
[0037] like Figure 1 , 2 As shown in Figures 5 and 6,
[0038] The switch block 200 has two abutment blocks 201 at its bottom ends. The two abutment blocks 201 are symmetrically arranged on the switch block 200. Each abutment block 201 has an extension block 302 at the end of each of the two connecting rods 301. The connecting rods 301 and the extension blocks 302 form an L-shaped structure, and the connecting rods 301, the extension blocks 302 and the slide rods 300 form a concave structure. The outer end face of the extension block 302 on one slide rod 300 and the inner end face of the other slide rod 300 are both located directly below the abutment block 201. When any abutment block 201 moves down, the two slide rods 300 can move synchronously in opposite directions.
[0039] That is, during the downward movement of the switch block 200, the abutment block 201 can also abut against the inner end face of the slide rod 300 and the outer end face of the extension block 302 on the other slide rod 300, so that when one end of the switch block 200 moves downward, the two slide rods 300 move in opposite directions. In addition, in cooperation with the transmission component 400, the two slide rods 300 can be more stable when sliding.
[0040] like Figure 1 , 2 As shown in Figures 5 and 6,
[0041] One of the slide bars 300 and the extension block 302 on the other slide bar 300 have a V-shaped storage groove. The storage groove is vertically aligned with the lower end of the contact block 201. The opening width of the storage groove is greater than the lower end width of the contact block 201. When the contact block 201 moves down, the end of the contact block 201 can move into the storage groove. That is, each of the storage grooves has an upward-facing opening, and when the contact block 201 moves down, the end of the contact block 201 can move into the opening, thereby causing the slide bar 300 and the extension block 302 on the other slide bar 300 to move in opposite directions.
[0042] like Figure 1 , 2 As shown in Figures 5 and 6,
[0043] The inner end faces of the two slide rods 300 are provided with a second inclined surface 303, and the outer end face of the extension block 302 on each slide rod 300 is provided with a third inclined surface 304. When the second inclined surface 303 and the third inclined surface 304 are symmetrical to each other and abut together, they can form a V-shaped storage groove. Thus, when the abutting block 201 moves down, the bottom of the abutting block 201 abuts against the second inclined surface 303 and the third inclined surface 304. This allows the slide rod 300 and the extension block 302 on the other slide rod 300 to move in opposite directions, thereby allowing the two slide rods 300 to move in opposite directions.
[0044] Meanwhile, the inner end face of the slide bar 300 and the outer end face of the extension block 302 on the slide bar 300 can also be set as arc surfaces, and the two arc surfaces are symmetrically arranged. Thus, when the abutment block 201 moves down, it can also abut against the two arc surfaces at the same time, causing the slide bar 300 and the extension block 302 on the other slide bar 300 to move in opposite directions, thereby enabling the two slide bars 300 to move in opposite directions.
[0045] like Figure 1 , 2 As shown in Figures 5 and 6,
[0046] The bottom end of the abutment block 201 is symmetrically provided with first inclined surfaces 202. When the abutment block 201 moves downward, the two first inclined surfaces 202 can abut against the second inclined surface 303 and the third inclined surface 304 respectively. That is, when the abutment block 201 moves downward, the two first inclined surfaces 202 can simultaneously abut against the second inclined surface 303 and the third inclined surface 304. This can indirectly make the two sliding rods 300 move synchronously in opposite directions. Furthermore, the two first inclined surfaces 202 can fit into the second inclined surface 303 and the third inclined surface 304, which can increase the contact area and make the sliding rods 300 more stable when moving.
[0047] like Figure 1 , 2 As shown in Figures 5 and 6,
[0048] The connecting rods 301 are all located on the sides of the two abutting blocks 201. That is, the two sets of connecting rods 301 and abutting blocks 201 are in an L-shaped structure, and the two sets of connecting rods 301 and abutting blocks 201 are distributed on both sides of the two abutting blocks 201. In this way, the connecting rods 301 will not abut against the abutting blocks 201 when they slide.
[0049] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0050] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
