[0006] The purpose of the present utility model is to provide a pull rod installation assembly to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The utility model is a pull rod installation assembly, including a pull rod structure, which is installed on the inner wall of one side of the top of the suitcase, and the suitcase includes a limit block, and the inner walls on both sides of the limit block are slidably connected with pull rods, and the top ends of the two pull rods are installed with sleeves, and the inner wall of the sleeve is provided with a button rod, and the bottom ends of the button rod are respectively provided with tensile ribs, and a compression spring is installed on the middle inner wall of the button rod, and the compression spring is inside the button rod and the sleeve. The purpose of such a setting is that when the trolley case is in use, the handheld trolley structure is pushed forward, and the trolley structure is limited by the limit blocks through the two trolleys. The limit blocks fix the trolley in the case body and extend and retract it up and down, and the case body is driven to move forward by the trolley structure, and the case body drives the rotating wheel to roll and move on the ground. When the trolley structure is not in use, the button rod is pressed, and the button rod squeezes the compression spring downward to contract, and the two ends of the button rod move downward to drive the connected tensile ribs to move downward and tighten. When the tensile ribs are tightened, the trolley is driven to contract and move downward within the limit blocks and the case body, and the entire trolley structure is accommodated by the accommodating groove to prevent the top of the trolley structure from protruding compared to the case body, thereby reducing To avoid the safety hazard of the pull rod structure being bumped, the upper and lower sides of the button rod are limited and fixed by the sleeve shell and the mounting shell. Since the rubber pad is deformable, the design of the rubber pad prevents the compression spring from driving the button rod to bounce upward and getting stuck in the mounting shell. The two ends of the mounting shell are fixed in the sleeve shell by clamping blocks. The two ends of the rubber pad are limited together just above the button rod by the two clamping blocks, and the two sides of the button rod are limited by the two clamping blocks in the sleeve shell to ensure the stable up and down movement of the button rod. When it is necessary to repair parts such as the button rod and the tensile rib, the mounting shell and the rubber pad are removed from above the button rod in turn to expose the button rod and the tensile rib, thereby improving the practicality of the pull rod structure.

[0009] Furthermore, a rubber pad is sleeved on the upper surface of the button rod, and a mounting shell is provided on the upper surface of the rubber pad. This arrangement is intended to prevent the button rod from getting stuck in the mounting shell when it is pushed upward by the compression spring during use, as the rubber pad is deformable.

[0010] Furthermore, the projection of the button rod extends upward through the rubber pad to the outside of the mounting shell. The purpose of this arrangement is that during the use of the trolley case, the two ends of the rubber pad are restricted together just above the button rod by the two clamping blocks.

[0011] Furthermore, the mounting shell has two outer walls at both sides of the bottom provided with a retaining block, the bottom ends of which are mounted on the inner wall of the sleeve. This arrangement is intended to ensure that when the suitcase is in use, the mounting shell is fixed to the sleeve via the retaining blocks at both ends, thereby securing the upper and lower sides of the button rod in position through the sleeve and the mounting shell.

[0012] Furthermore, the luggage case includes a case body, a receiving groove is provided on the outer wall of the top side of the case body, and the stopper is mounted on the inner wall of the receiving groove. This arrangement is intended to ensure that when the luggage case is in use, the tensioning ribs tighten, causing the drawbar to retract and move downward within the stopper and the case body, and the entire drawbar structure is stored in the receiving groove.

[0013] Furthermore, the bottom ends of the two tensile ribs extend to the inner wall of the case, and rotating wheels are mounted at the corners of the case's bottom surface. This arrangement allows the case to be used by holding the pull rod structure forward, where it is restrained by two stoppers, securing it within the case. The tensile ribs extend and retract, driving the case forward through the pull rod structure, which in turn drives the rotating wheels to roll across the ground.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model fixes the upper and lower sides of the key rod by setting the stretching rib, the block and the housing. The two ends of the housing are fixed in the housing by the block. The two ends of the rubber pad are limited at the top of the key rod by the two blocks. The two sides of the key rod are limited by the two blocks in the housing. When the key rod and the stretching rib need to be repaired, the housing and the rubber pad are removed from the top of the key rod in turn to expose the key rod and the stretching rib.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1 - Figure 4As shown, the utility model is a pull rod installation assembly, including a pull rod structure 2, which is installed on the inner wall of the top side of the suitcase 1, and the suitcase 1 includes a limit block 104, and the inner walls on both sides of the limit block 104 are slidably connected to the pull rods 201, and the tops of the two pull rods 201 are installed with a shell 202, and a button rod 204 is provided on the inner wall of the shell 202, and tensile ribs 208 are respectively provided at the two ends of the bottom of the button rod 204, and a compression spring 207 is installed on the middle inner wall of the button rod 204, and the compression spring 207 is located in the button rod 204 and the shell 202. The purpose of such arrangement is that when the trolley case is in use, the handheld trolley structure 2 is pushed forward, and the trolley structure 2 is limited by the limit blocks 104 through the two trolleys 201. The limit blocks 104 fix the trolley 201 in the box body 101 for upward and downward extension, and the box body 101 is driven forward by the trolley structure 2, and the box body 101 drives the rotating wheel 102 to roll on the ground. When the trolley structure 2 is not in use, the button rod 204 is pressed downward, and the button rod 204 squeezes the compression spring 207 to contract, and the two ends of the button rod 204 move downward, driving the connected tensile ribs 208 to move downward and tighten. When the tensile ribs 208 are tightened, the trolley 201 is driven to contract and move downward in the limit blocks 104 and the box body 101, and the entire structure of the trolley structure 2 is accommodated by the accommodating groove 103, so as to prevent the top of the trolley structure 2 from protruding compared with the box body 101, thereby reducing the risk of the trolley structure 2 being knocked. The safety hazard of collision is eliminated by limiting the upper and lower sides of the button rod 204 through the cover shell 202 and the mounting shell 203. Since the rubber pad 206 is deformable, the design of the rubber pad 206 prevents the compression spring 207 from driving the button rod 204 to bounce upward and get stuck in the mounting shell 203. The two ends of the mounting shell 203 are fixed in the cover shell 202 through the clamping blocks 205. The two ends of the rubber pad 206 are limited at the top of the button rod 204 through the two clamping blocks 205. The two sides of the button rod 204 are limited by the two clamping blocks 205 in the cover shell 202 to ensure that the button rod 204 can move stably up and down. When it is necessary to repair the button rod 204 and the tensile rib 208 and other parts, the mounting shell 203 and the rubber pad 206 are removed from the top of the button rod 204 in turn to expose the button rod 204 and the tensile rib 208, thereby improving the practicality of the pull rod structure 2.

[0026] A rubber pad 206 is sleeved on the upper surface of the button rod 204, and a mounting shell 203 is provided on the upper surface of the rubber pad 206. This arrangement is intended to prevent the button rod 204 from getting stuck in the mounting shell 203 when the compression spring 207 drives it upward when the rubber pad 206 is deformable during use of the suitcase.

[0027] The projection of the button rod 204 extends upward through the rubber pad 206 to the outside of the mounting shell 203. The purpose of this arrangement is that during the use of the trolley case, the two ends of the rubber pad 206 are limited together just above the button rod 204 by the two clamping blocks 205.

[0028] A clamping block 205 is provided on each side of the bottom outer wall of the mounting shell 203. The bottom ends of the two clamping blocks 205 are mounted on the inner wall of the cover shell 202. This arrangement ensures that when the suitcase is in use, the mounting shell 203 is fixed to the cover shell 202 at both ends via the clamping blocks 205, and the upper and lower sides of the button rod 204 are fixed by the cover shell 202 and the mounting shell 203.

[0029] The luggage case 1 includes a body 101, with a receiving slot 103 formed on one outer wall of the top side of the body 101. A stopper 104 is mounted on the inner wall of the receiving slot 103. This arrangement allows the tensioning rib 208 to contract and move the pull rod 201 downward within the stopper 104 and the body 101 during use, allowing the entire pull rod structure 2 to be stored within the receiving slot 103.

[0030] The bottom ends of the two tensile ribs 208 extend to the inner wall of the box 101. Wheels 102 are mounted at the corners of the bottom of the box 101. This arrangement ensures that when the trolley case is used, the pull rod structure 2 is pushed forward by the two pull rods 201. The pull rods 201 are restrained by the stoppers 104, which secure the pull rods 201 within the box 101. The tensile ribs 208 extend and retract, driving the box 101 forward through the pull rod structure 2. The box 101 then drives the wheels 102 to roll across the ground.

[0031] When in use, the handheld pull rod structure 2 is pushed forward, and the pull rod structure 2 is limited by the limit block 104 through the two pull rods 201. The limit block 104 fixes the pull rod 201 in the box body 101 for upward and downward extension, and the box body 101 is driven forward by the pull rod structure 2, and the box body 101 drives the rotating wheel 102 to roll on the ground. When the pull rod structure 2 is not in use, the button rod 204 is pressed downward, and the button rod 204 squeezes the compression spring 207 to contract, and the two ends of the button rod 204 move downward, driving the connected tensile rib 208 to move downward and tighten. When the tensile rib 208 is tightened, the pull rod 201 is driven to shrink and move downward in the limit block 104 and the box body 101, and the entire structure of the pull rod structure 2 is stored through the accommodating groove 103 to prevent the top of the pull rod structure 2 from protruding compared to the box body 101, thereby reducing the risk of the pull rod structure 2 being bumped. The two clamping blocks 205 in the sleeve 202 limit the two ends of the rubber pad 206 just above the button rod 204, and the two clamping blocks 205 in the sleeve 202 limit the two sides of the button rod 204 to ensure that the button rod 204 can move stably up and down. When it is necessary to repair the button rod 204 and the tensile rib 208 and other parts, the mounting shell 203 and the rubber pad 206 are removed from the top of the button rod 204 in turn to expose the button rod 204 and the tensile rib 208, thereby improving the practicality of the pull rod structure 2.
