Description

Technical Field

[0001] This utility model relates to the field of logistics conveying equipment technology, and in particular to a quick-installation and quick-release locking rubber sleeve. Background Technology

[0002] In logistics conveying equipment, rollers need to be fitted with rubber sleeves to improve friction, insulation, and wear resistance, preventing material slippage or roller damage. A common method is to wrap a rubber layer around the roller surface, but this method makes disassembly, replacement, and repair inconvenient once the rubber layer is damaged.

[0003] Existing patent: Chinese utility model patent CN218289303U discloses a roller locking sleeve. This locking sleeve adopts a split structure, but suffers from low disassembly and assembly efficiency and strong tool dependence. To address these issues, a locking sleeve that requires no multiple tools, involves fewer operation steps, can be quickly assembled and disassembled, and also ensures stability is needed to meet the requirements of efficient maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a quick-install and quick-release locking sleeve to solve the problems mentioned in the background art.

[0005] The above-mentioned objective of this utility model is achieved through the following technical solution: a quick-installation and quick-removal locking sleeve, comprising two semi-circular spacers joined together from left to right, and further comprising: a positioning post and a connecting block; One end of the positioning post is fixed to the inner wall of the spacer and extends in the radial direction; The connecting block connects between the two spacers; A connecting hole is provided on the outer wall of the spacer near the splicing surface, and the two ends of the connecting block are respectively embedded in the connecting holes of the two spacers; The connecting hole has a positioning hole on its wall, and the connecting block has elastic positioning elements on its side walls at both ends that can be inserted into the positioning hole.

[0006] Preferably, the outer wall of the spacer is provided with a groove, two adjacent grooves of the two spacers are interconnected, the connecting block is embedded in the two grooves, and the connecting hole is set in the corresponding groove.

[0007] Preferably, the connecting block has radially protruding embedded end blocks at both ends, which are embedded in the connecting hole.

[0008] Preferably, the connecting block is arc-shaped, and the outer wall of the connecting block and the outer wall of the spacer are located within the same circumference.

[0009] Preferably, the elastic positioning element includes a positioning end and a spring. The side wall of the connecting block is provided with a mounting hole, the spring is disposed in the mounting hole, one end of the positioning end is inserted into the mounting hole and connected to the spring, and the other end is inserted into the positioning hole.

[0010] Preferably, the end of the positioning head inserted into the positioning hole is hemispherical.

[0011] Preferably, the splicing surfaces of the two spacers are respectively provided with oriented positioning blocks and positioning slots.

[0012] The beneficial effects of this utility model are: This utility model replaces the traditional complex connection methods such as bolts and clips that require tools for disassembly by using a combination structure of "connecting block embedded in connecting hole + elastic positioning element snapped into positioning hole". During assembly, simply align the two ends of the connecting block with the connecting hole of the spacer and insert it. The elastic positioning element will automatically snap into the positioning hole to complete the fixation. During disassembly, simply pull the connecting block radially to make the elastic positioning element disengage from the positioning hole to quickly separate the two spacers. This significantly shortens the operation time for installation and disassembly, and is especially suitable for scenarios that require frequent maintenance or replacement. The positioning hole on the wall of the connecting hole and the elastic positioning element on the side wall of the connecting block form a two-way locking structure. The elastic force of the elastic positioning element itself can always maintain a tight contact with the positioning hole, and even under conditions such as vibration and impact, it can effectively prevent the connecting block from coming out of the connecting hole. At the same time, the two spacers form a rigid connection through the connecting block, and it is not easy for gaps or relative sliding to occur after splicing, ensuring that the locking and protection function of the rubber sleeve on the connected parts is stable and durable.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0016] Example: like Figure 1 and Figure 5 As shown, a quick-install and quick-release locking sleeve includes two semi-circular spacers 1, which are spliced ​​together and fitted onto the outside of the roller.

[0017] A positioning post 101 is installed on the inner wall of the spacer 1. One end of the positioning post 101 is fixed to the inner wall of the spacer 1 and extends in the radial direction. The positioning post 101 can be integrally formed with the spacer 1 or screwed onto the spacer 1.

[0018] The roller has corresponding through holes on its wall. When the spacer 1 is installed, the positioning pin 101 is inserted into the through hole so that the spacer 1 is positioned in the axial and circumferential directions.

[0019] like Figure 1-4 As shown, the two spacers 1 are connected by connecting blocks 2, which are installed between the two joints of the spacers 1. Specifically, each joint has at least two connecting blocks 2, which are spaced apart along the axial direction.

[0020] The splicing surfaces of the two spacers 1 are respectively provided with oriented positioning blocks 107 and positioning slots 106. When the two spacers 1 are spliced, the positioning blocks 107 are inserted into the corresponding positioning slots 106, so that the two spacers 1 are initially positioned, which facilitates the installation of the connecting block 2.

[0021] A connecting hole 103 is provided on the outer wall of the spacer 1 near the splicing surface. The two ends of the connecting block 2 are provided with radially protruding embedded end blocks 201, which are embedded in the connecting hole 103. When the two spacers 1 move apart in the radial direction, the embedded end blocks 201 cooperate with the connecting hole 103 to prevent the two spacers 1 from separating.

[0022] The connecting block 2 is arc-shaped, and the outer wall of the connecting block 2 and the outer wall of the spacer 1 are located within the same circumference.

[0023] The outer wall of the spacer 1 is provided with a groove 102. The two adjacent grooves 102 of the two spacers 1 are connected to each other. The connecting block 2 is embedded in the two grooves 102. The connecting hole 103 is set in the corresponding groove 102. This can ensure that the outer wall of the connecting block 2 does not protrude from the outer wall of the spacer 1.

[0024] like Figure 4 As shown, a positioning hole 104 is provided on the wall of the connecting hole 103, and elastic positioning elements 3 that can be inserted into the positioning hole 104 are provided on the side walls at both ends of the connecting block 2. This can prevent the connecting block 2 from separating from the spacer 1 and ensure that the two spacers 1 are connected as a whole through the connecting block 2.

[0025] The elastic positioning element 3 includes a positioning end 301 and a spring 302. A mounting hole 202 is provided on the side wall of the connecting block 2. The spring 302 is disposed within the mounting hole 202. One end of the positioning end 301 is inserted into the mounting hole 202 and connected to the spring 302, while the other end is inserted into the positioning hole 104. The end of the positioning end 301 inserted into the positioning hole 104 is hemispherical to facilitate the entry and exit of the positioning end 301 from the positioning hole 104. The diameter of the positioning hole 104 is slightly larger than the diameter of the positioning end 301.

[0026] When the roller rotates, the two spacers 1 tend to separate radially under centrifugal force, causing the inner wall of the connecting hole 103 to fit tightly against the inner end face of the embedded end block 201, generating a large frictional force to prevent the positioning block 107 from disengaging from the groove 102. To increase this frictional force, a rubber sheet is provided on the end face or hole wall of the embedded end block 201 that fits against the connecting hole 103.

[0027] During assembly, first insert the positioning pins 101 of the two spacers 1 into the corresponding through holes of the roller, and then splice the two together so that the positioning blocks 107 at the splicing surface are respectively inserted into the corresponding positioning slots 106, so that the two spacers 1 are initially positioned; then place the positioning blocks 107 into the grooves 102 and apply pressure in the radial direction so that the positioning blocks 107 are embedded in the grooves 102 until the positioning end 301 of the elastic positioning member 3 is inserted into the positioning hole 104, at which point the assembly of the spacers 1 is completed.

[0028] To facilitate the disassembly of the connecting block 2, reserved slots 105 are provided on both sides of the groove 102, so that the operator can insert the fingertips into the reserved slots 105 to grasp the connecting block 2. By applying a radial pulling force to the connecting block 2, the hemispherical end of the positioning end 301 is disassembled from the positioning hole 104, thereby disassembling the connecting block 2.
