Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical equipment technology, specifically relating to a small protective cover that is easy to disassemble and install. Background Technology
[0002] As the country continues to raise safety requirements for processing enterprises, the inherent safety of equipment is gradually improving. Effective safety protection must be installed for rotating parts. Protective covers are very common components in processing enterprises and are an effective means of ensuring worker safety.
[0003] The dewatering rollers of the stretch bending straightening machine are a crucial component of the machine, and they frequently need to be replaced due to production requirements. Each replacement necessitates the removal and installation of a protective cover. Since the protective cover is primarily secured with screws, numerous screws need to be removed, and the process requires coordinated personnel: one person holds the cover while another removes and installs the screws. The existing method of removing and installing the protective cover is inefficient, requires multiple operators, and results in significant waste of human resources.
[0004] Therefore, there is an urgent need for a small protective cover that does not require multiple people to operate and is easy to disassemble and install. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a small protective cover that is easy to disassemble and install, aiming to solve the problem that the existing protective covers are inconvenient to disassemble and install and require multiple people to operate together.
[0006] This utility model solves the above-mentioned technical problems through the following technical means:
[0007] A small protective cover that is easy to disassemble and install includes a support base and a fixing mechanism. The support base is fixedly connected to the outer shell of a tension bending straightening machine by bolts. A cover body is provided at the upper limit of the support base. An L-shaped extension plate is provided at one end of the cover body away from the support base. The fixing mechanism is located directly above the cover body and is used to fix the extension plate.
[0008] Furthermore, the fixing mechanism includes a base fixedly mounted on the surface of the outer shell of the tension bending straightening machine and a fixing clamp rotatably connected to the base. A torsion spring is provided between the fixing clamp and the base. A rubber protective sleeve is provided on the pressing part of the fixing clamp. The clamping end of the fixing clamp faces the extension plate. A limit hole is provided on the extension plate of the cover. The clamping end of the fixing clamp is provided with a positioning pin that cooperates with the limit hole. The torsion spring can drive the positioning pin of the clamping end of the fixing clamp to move toward the limit hole under elastic action.
[0009] This structural design allows for quick fixing and unfixing of the extension plate at the top of the cover via a fixing mechanism. The operation is simple and efficient, and one person can disassemble and arrange the cover.
[0010] Furthermore, the clamping end of the fixing clamp has a strip-shaped hole, the positioning pin is disposed in the strip-shaped hole, the positioning pin is provided with a baffle, and the end of the positioning pin near the strip-shaped hole extends out of the strip-shaped hole and is threadedly connected to a locking nut. The positioning pin is fixedly connected to the strip-shaped hole through the baffle and the locking nut.
[0011] This structural design allows for flexible adjustment or replacement of the locating pins as needed, thus adapting to different positions and sizes of limiting holes, making it more versatile.
[0012] Furthermore, the upper side of the support base is provided with a slot that matches the lower end of the cover, and the cover is engaged with the support base through the slot.
[0013] Furthermore, the cover is rotatably connected to the support base via a hinge.
[0014] With this structural design, the lower end of the cover is fixed by a slot or hinge, so that during subsequent disassembly and assembly, no other personnel are needed to hold the cover. One person can disassemble and assemble the cover, avoiding the waste of human resources.
[0015] Beneficial effects:
[0016] This utility model discloses a small protective cover that is easy to disassemble and install. It includes a support base, cover body, extension plate, limiting holes, a base, torsion spring, fixing clips, and positioning pins, making the disassembly and assembly of the cover efficient and convenient. The cover body will not fall or shift during the disassembly and assembly process, and can be disassembled and assembled by only one person, avoiding the waste of manpower. This small protective cover also features a strip-shaped hole, allowing for flexible adjustment or replacement of the positioning pin as needed, thus adapting to limiting holes of different positions and sizes, enhancing its applicability and making it suitable for widespread use.

The support base 1 is fixedly connected to the outer shell of the tension bending straightening machine by bolts. A cover body 2 is provided at the upper limit of the support base 1. In this embodiment, a slot is provided on the upper side of the support base 1 to cooperate with the lower end of the cover body 2. The cover body 2 is engaged with the support base 1 through the slot. An L-shaped extension plate 3 is provided at the end of the cover body 2 away from the support base 1. The fixing mechanism is located directly above the cover body 2 and is used to fix the extension plate 3.
[0025] The fixing mechanism includes a base fixedly mounted on the surface of the outer shell of the tension bending straightening machine and a fixing clamp 4 rotatably connected to the base. A torsion spring is provided between the fixing clamp 4 and the base. The pressing part of the fixing clamp 4 is covered with a rubber protective sleeve. The clamping end of the fixing clamp 4 is directly opposite the extension plate 3. A limit hole is provided on the extension plate 3 of the cover 2. The clamping end of the fixing clamp 4 is provided with a positioning pin 5 that cooperates with the limit hole. The torsion spring can drive the positioning pin 5 of the clamping end of the fixing clamp 4 to move toward the limit hole under the elastic action.
[0026] The clamping end of the fixing clamp 4 has a strip-shaped hole 6, the positioning pin 5 is set in the strip-shaped hole 6, the positioning pin 5 is provided with a baffle, the end of the positioning pin 5 near the strip-shaped hole 6 extends out of the strip-shaped hole 6 and is threadedly connected to a locking nut, and the positioning pin 5 is fixedly connected to the strip-shaped hole 6 through the baffle and the locking nut.
[0027] First, the support base 1 and the base are fixed to the outer shell of the tension bending straightening machine by means of bolt connection or welding.
[0028] When replacing the squeezing roller, first remove the cover 2, press down the pressing part of the fixing clamp 4 to release the fixing pin 5 at the clamping end of the fixing clamp 4 from the limiting hole of the upper extension plate 3 of the cover 2, then remove the cover 2 and replace the squeezing roller. After the squeezing roller is replaced, reinstall the cover 2. First, press down the pressing part of the fixing clamp 4 to place the cover 2 stably on the slot of the support base 1. After the cover 2 is placed, release the force applied to the pressing part of the fixing clamp 4.
