Description

Technical Field

[0001] This utility model relates to the field of trolley case technology, specifically to a mounting plate base for trolley case wheels. Background Technology

[0002] A rolling suitcase refers to a suitcase with a pull handle and wheels. Commonly used rolling suitcase wheels include one-way wheels, single-wheel swivel wheels, and aircraft wheels. Among them, single-wheel swivel wheels can rotate 360 ​​degrees and move easily on flat surfaces. They can also be pushed sideways when passing through narrow spaces. The mounting plate for the rolling suitcase wheels is an important component used to fix and install the rolling suitcase wheels. It can securely connect the wheels to the rolling suitcase body, ensuring that the wheels will not easily loosen or fall off during use, guaranteeing the normal use of the rolling suitcase, and can bear the weight of the rolling suitcase and its contents, evenly distributing the weight to the wheels, so that the wheels can better support and roll the rolling suitcase.

[0003] CN206049228U discloses a mounting base for a luggage caster, comprising a horizontally placed base plate. The outer contour of the base plate includes a first straight edge and a second straight edge perpendicular to the first straight edge. One end of the first straight edge and one end of the second straight edge are connected by a rounded corner to form a first rounded corner edge. The other end of the first straight edge and the other end of the second straight edge are connected by a first arc edge. The first straight edge, the first rounded corner edge, and the second straight edge all extend vertically upward to form a first straight baffle, a first rounded corner plate, and a second straight baffle connected in sequence. The base plate has a through mounting hole for the caster to be installed near the first rounded corner edge. It has high stability, is safe and reliable, has a stable structure, is easy to disassemble and assemble, and is aesthetically pleasing.

[0004] While the existing technology CN206049228U has many advantages in use, it still has the following problems: its practicality for the substrate is not perfect. It can only be used to assemble wheels and the box body. However, when the wheels roll on the ground, dust and foreign objects will adhere to the contact surface between the wheels and the ground. The dust and foreign objects will be lifted up with the rolling wheels, causing contamination to the substrate and thus contaminating the outer wall of the suitcase. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a mounting plate base for a suitcase wheel.

[0006] The technical solution adopted by this utility model to solve its technical problem is a mounting plate base for a trolley case wheel, including a base plate, a shield, and a fixing ring. An assembly column is installed inside the base plate. A fixing ring is fused to one side of the lower outer wall of the base plate. A support ring is provided on the outside of the fixing ring. Support arms are fused to both outer walls of the support ring. A shield is provided on the lower outer wall of the base plate. Equally spaced parallel brushes are glued and fixed to the inner wall of the shield. Guide holes are opened on both outer walls of the shield. Guide rods are provided inside the guide holes. A sleeve is installed on the outer wall of one end of the guide rod. A clamping wheel is connected to the inner pin of the sleeve.

[0007] By adopting the above technical solution, the assembly column is used to connect the connecting shaft of the trolley case roller, which can ensure the firmness of the connection between the base plate and the roller. The support arm is used to assemble the shield, keeping the shield in a relatively good position at the lower end of the base plate. The shield can also shield the outside of the roller, preventing dust and foreign objects adhering to the outer wall of the roller from being stirred up, reducing the degree of contamination to the base plate or the outer wall of the trolley case. The brush can clean the outer wall of the roller. Through the cyclical contact between the roller and the brush during the rolling process, dust and foreign objects can be scraped and cleaned, ensuring the relative cleanliness of the roller and effectively ensuring the performance and cleanliness of the case roller.

[0008] Specifically, the upper outer wall of the substrate is fused with a circular array of assembly columns, and the upper outer wall of the substrate is fused with reinforcing ribs to increase structural strength. The reinforcing ribs are fused to the assembly columns and the outer walls of the assembly columns respectively.

[0009] By adopting the above technical solution, the assembly columns on the substrate can be easily connected to the luggage box body, increasing the connection stability. The reinforcing ribs are fused to the assembly columns and the mounting posts respectively, which enhances the structural strength of the substrate, improves the overall load-bearing capacity and durability of the mounting plate base, and reduces the risk of substrate damage caused by external forces.

[0010] Specifically, the outer wall of the fixed ring is interference-fitted with a bearing, the inner ring of the support ring is interference-fitted with the outer ring of the bearing, and the support ring is rotatably connected to the fixed ring through the bearing.

[0011] By adopting the above technical solution, the bearing enables the support ring to rotate flexibly. Thus, when the roller rotates in all directions, the shielding cover rotates with the roller through the support ring, ensuring the continuous shielding of the roller by the shielding cover.

[0012] Specifically, the outer wall of the support arm opposite to the support ring has a screw hole, and the outer walls of both sides of the shield are movably installed with fixing bolts to maintain the connection strength. The fixing bolts pass through one side of the shield and are threaded into the screw hole.

[0013] By adopting the above technical solution, the screw holes and fixing bolts can achieve a firm connection between the shield and the support arm, ensuring that the shield is stable in position during use and can continuously play its role in blocking dust and debris, while also facilitating disassembly and maintenance.

[0014] Specifically, the inner wall of the guide hole and the outer wall of the guide rod are both designed in a rectangular shape. The size of the guide rod is smaller than the inner wall size of the guide hole, and the guide rod is movably installed inside the guide hole.

[0015] By adopting the above technical solution, the guide hole can both restrict the movement direction of the guide rod, making it slide only in a specific direction, and ensure that the guide rod can move flexibly within the guide hole. This provides a stable and flexible guiding structure for adjusting the position of the clamping wheel, ensuring that the clamping wheel can continuously contact the side wall of the box wheel through the spring force. This ensures that the relative position of the shielding cover on the outside of the box wheel is stable, allowing the shielding cover to rotate with the box wheel. When the box wheel rotates, the clamping wheel rotates accordingly, avoiding any impact on the normal rotation of the box wheel. Furthermore, the adjustable position of the clamping wheel can accommodate box wheels of different sizes, ensuring the applicability of the equipment.

[0016] Specifically, the guide rod is screwed to a limiting plate on the outer wall of the end opposite to the sleeve to restrict its movement trajectory. The limiting plate is located on the outside of the sleeve.

[0017] By adopting the above technical solution, the limiting plate can prevent the guide rod from sliding out of the guide hole, restrict the movement trajectory of the guide rod, and ensure that the clamping wheel moves within a suitable range.

[0018] Specifically, a spring is sleeved on the outer side of the guide rod, and the two ends of the spring are in contact with the outer wall of the sleeve and the inner wall of the shield, respectively. The sleeve is elastically connected to the inner wall of the shield through the spring.

[0019] By adopting the above technical solution, the spring force can drive the clamping wheel to clamp the side wall of the trolley case wheel, and give the clamping wheel a certain buffering and self-adaptive ability.

[0020] The beneficial effects of this utility model are:

[0021] (1) The mounting plate base for a trolley wheel described in this utility model has a shield that can shield the outside of the roller, preventing dust and foreign objects adhering to the outer wall of the roller from being lifted up, reducing the degree of contamination to the base plate or the outer wall of the trolley. The brush can clean the outer wall of the roller. Through the cyclic contact between the roller and the brush during the rolling process, dust and foreign objects can be scraped and cleaned, ensuring the relative cleanliness of the roller and effectively ensuring the performance and cleanliness of the trolley wheel.

[0022] (2) The mounting plate base for the wheel of the trolley case described in this utility model has a clamping wheel that rotates along with the case wheel when the case wheel rotates, which avoids affecting the normal rotation of the case wheel. Furthermore, the clamping wheel can be adjusted by the position of the clamping wheel, which can adapt to case wheels of different sizes and ensure the applicability of the equipment.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention provides a mounting plate base for a trolley case wheel, comprising a base plate 1, a shield 2, and a fixing ring 3. An assembly column 11 is installed inside the base plate 1. A fixing ring 3 is fused to one side of the lower outer wall of the base plate 1. A support ring 32 is provided on the outside of the fixing ring 3. Support arms 33 are fused to both sides of the outer wall of the support ring 32. A shield 2 is provided on the lower outer wall of the base plate 1. Brushes 22 are equidistantly and parallelly distributed on the inner wall of the shield 2. Guide holes 23 are provided on both sides of the outer wall of the shield 2. Guide rods 24 are provided inside the guide holes 23. A sleeve 27 is installed on the outer wall of one end of the guide rod 24. A clamping wheel 28 is connected to the inside of the sleeve 27 by a pin.

[0031] In use, the assembly column 11 is used to connect the connecting shaft of the rolling wheel of the suitcase, which can ensure the connection between the base plate 1 and the rolling wheel. The support arm 33 is used to assemble the shield 2, which can keep the shield 2 in a relatively good position at the lower end of the base plate 1. The shield 2 can shield the outside of the rolling wheel, preventing dust and foreign objects adhering to the outer wall of the rolling wheel from being lifted up, reducing the degree of contamination to the base plate 1 or the outer wall of the suitcase. The brush 22 can clean the outer wall of the rolling wheel. Through the cyclic contact between the rolling wheel and the brush 22 during the rolling process, dust and foreign objects can be scraped and cleaned, ensuring the relative cleanliness of the rolling wheel. This can effectively ensure the performance and cleanliness of the suitcase wheel. The center positions of the assembly column 11 and the fixing ring 3 are on the same vertical line.

[0032] To ensure structural strength, for example, such as Figure 1 As shown, the upper outer wall of the substrate 1 is welded with assembly columns 12 arranged in a circular array, and the upper outer wall of the substrate 1 is welded with reinforcing ribs 13 for increasing structural strength. The reinforcing ribs 13 are welded to the outer walls of the assembly columns 11 and 12 respectively.

[0033] In use, the assembly column 12 on the base plate 1 is convenient to connect with the trolley case body, increasing the connection stability. The reinforcing rib 13 is fused to the assembly column 11 and the assembly column 12 respectively, which enhances the structural strength of the base plate 1, improves the overall load-bearing capacity and durability of the mounting plate base, and reduces the risk of damage to the base plate 1 caused by external forces.

[0034] For smooth rotation, for example, such as Figure 2 As shown, the outer wall of the fixed ring 3 is interference-fitted with the bearing 31, and the inner ring of the support ring 32 is interference-fitted with the outer ring of the bearing 31. The support ring 32 is rotatably connected to the fixed ring 3 through the bearing 31.

[0035] In use, the bearing 31 allows the support ring 32 to rotate flexibly, so that when the roller rotates in all directions, the shield 2 rotates with the roller through the support ring 32, ensuring the continuous shielding of the roller by the shield 2.

[0036] To maintain connection strength, for example, such as Figure 2 As shown, the outer wall of the support arm 33 opposite to the support ring 32 has a screw hole, and the outer walls of both sides of the shield 2 are movably installed with fixing bolts 21 to maintain the connection strength. The fixing bolts 21 pass through one side of the shield 2 and are threaded into the screw hole.

[0037] During use, the screw holes and fixing bolts 21 can achieve a firm connection between the shield 2 and the support arm 33, ensuring that the shield 2 is stable in position during use and can continuously play its role in blocking dust and debris, while also facilitating disassembly and maintenance.

[0038] To adjust the usage location, for example, such as Figure 3As shown, the inner wall of the guide hole 23 and the outer wall of the guide rod 24 are both designed in a rectangular shape. The size of the guide rod 24 is smaller than the inner wall size of the guide hole 23, and the guide rod 24 is movably installed inside the guide hole 23.

[0039] In use, the guide hole 23 can both restrict the movement direction of the guide rod 24, allowing it to slide only in a specific direction, and ensure that the guide rod 24 can move flexibly within the guide hole 23. This provides a stable and flexible guiding structure for adjusting the position of the clamping wheel 28, ensuring that the clamping wheel 28 can continuously contact the side wall of the box wheel through the elastic force of the spring 26. This ensures that the relative position of the shield 2 on the outside of the box wheel is stable, allowing the shield 2 to rotate with the box wheel. When the box wheel rotates, the clamping wheel 28 rotates accordingly, avoiding any impact on the normal rotation of the box wheel. Furthermore, the position of the clamping wheel 28 is adjustable, allowing it to adapt to box wheels of different sizes, ensuring the applicability of the equipment.

[0040] To limit the movement trajectory, for example, such as Figure 4 As shown, a limiting plate 25 for limiting the movement trajectory is screwed to the outer wall of the guide rod 24 away from the sleeve 27. The limiting plate 25 is located on the outside of the sleeve 27.

[0041] During use, the limiting plate 25 can prevent the guide rod 24 from sliding out of the guide hole 23, limit the movement trajectory of the guide rod 24, and ensure that the clamping wheel 28 moves within a suitable range.

[0042] To maintain the usage location, for example, such as Figure 4 As shown, a spring 26 is sleeved on the outer side of the guide rod 24. The two ends of the spring 26 are in contact with the outer wall of the sleeve 27 and the inner wall of the shield 2, respectively. The sleeve 27 is elastically connected to the inner wall of the shield 2 through the spring 26.

[0043] When in use, the spring 26 can drive the clamping wheel 28 to clamp the side wall of the trolley case wheel, and give the clamping wheel 28 a certain buffering and self-adaptive ability.

[0044] In use, the connecting shaft of the trolley case roller is mounted on the base plate 1 by the assembly column 11. At the same time, the base plate 1 is fixed to the trolley case body by the assembly column 12 on the base plate 1. The shield 2 is mounted on the support arm 33 by the fixing bolt 21. At this time, the brush 22 is in contact with the outer wall of the roller, while the clamping wheel 28 is in contact with the side wall of the case wheel by the elastic force of the spring 26. When the case wheel rotates, the shield 2 shields the case wheel, and the brush 22 cleans its outer wall when the roller rolls.

[0045] When the box wheel rotates, the clamping wheel 28 rotates accordingly, ensuring that the position of the shield 2 is stable and does not affect the rotation of the box wheel. At the same time, the shield 2 can rotate omnidirectionally with the roller through the bearing 31, continuously playing the shielding role.
