Abstract
Description
Technical Field
[0001] This application relates to the field of building construction, and in particular to an auxiliary device for plastering the external corners of building components. Background Technology
[0002] An external corner refers to a protruding corner on a wall. Plastering the surface of structural components is an important part of building construction, which is of great significance for improving the overall aesthetics and quality of the building. When plastering small concrete components, corner guards are usually made at the external corners to help control the lines at the corners and to determine the thickness of the plaster.
[0003] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: When using external corner protectors, auxiliary devices are needed to fix the corner protectors at the external corner position to prevent the position of the corner protectors from changing. Generally, a bent steel wire is used to clamp the two ends of the two corner protectors. The corner protectors are fixed by the inward elastic force when the steel wire is bent. However, this fixing method is relatively simple and cannot easily adjust the spacing according to the distance between the corner protectors of the components, nor can it move the clamping position accordingly, which hinders the plastering work. Utility Model Content
[0004] This application provides an auxiliary device for plastering the external corner of a component, which solves the problem in the prior art that the auxiliary fixing device cannot change the clamping position according to the width of the component, and realizes the effect of adjusting the spacing according to the position of the two corner guards on the component.
[0005] This application provides an auxiliary device for plastering the external corner of a component, including a fixed seat on one side of a concrete component, a corner protector provided at the external corner of the concrete component, movable plates slidably connected to both ends of the fixed seat near the concrete component, a movable component fixedly installed on the fixed seat, the movable component being used to drive the two movable plates to move towards the concrete component, a clamping component provided on the movable plate, the movable component driving the clamping component to press the corner protector onto the concrete component so that the corner protector does not move arbitrarily on the concrete component.
[0006] Furthermore, the clamping assembly includes: a pressure plate disposed on the side of the movable plate near the corner protector, and the pressure plate is in contact with the corner protector to press against the outside of the corner protector; two insert rods symmetrically disposed on both sides of the pressure plate, and the two insert rods are inserted and connected to the movable plate; and a fixing block disposed at the end of the insert rod away from the pressure plate.
[0007] Furthermore, a spring is sleeved on the outer side of the insertion rod, and the spring is disposed between the pressure plate and the movable plate.
[0008] Furthermore, a through groove is provided in the middle of the pressure plate, and a roller is provided inside the through groove. One side of the roller contacts the outer side of the corner protector.
[0009] Furthermore, the fixed base has a groove on the side facing the concrete component. The moving component includes: a bidirectional lead screw rotatably connected to the inside of the groove; a reduction motor installed on one side of the fixed base, with the output shaft of the reduction motor extending into the groove and fixedly connected to the bidirectional lead screw; and two movable blocks sleeved and threadedly connected to the two ends of the bidirectional lead screw, with the two movable blocks respectively fixed to the two movable plates. The movable blocks are slidably disposed between the inner walls on both sides of the groove.
[0010] The technical solution provided in this application has at least the following technical effects or advantages:
[0011] The rotation of the two-way screw drives two movable plates to move towards each other, allowing them to move to a suitable distance according to the gap between the two corner protectors. The spring force applies pressure to the corner protectors, ensuring that the two corner protectors with different gaps can be fixed and stable. This facilitates control of the lines at the external corners and clarifies the plaster thickness. The rollers on the pressure plate allow the auxiliary device to change position as plastering progresses, ensuring that the auxiliary device does not interfere with hand operation during plastering.

Detailed Implementation
[0017] This application discloses an auxiliary device for plastering the external corner of a component. The device uses a reduction motor 52 to drive a bidirectional lead screw 51 to rotate, thereby causing two movable plates 40 to move towards each other at a suitable position according to the distance between the two corner protectors 20. The movement of the movable plates 40 compresses the spring 63 between the pressure plate 61 and the movable plates 40. The elastic force of the spring 63 allows the pressure plate 61 to press tightly against the outside of the corner protector 20, preventing the corner protector 20 from moving, thereby controlling the lines at the external corner of the concrete component 10 and determining the plaster thickness.
[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0019] Please refer to Figure 1 and Figure 2 This embodiment provides an auxiliary device for plastering the external corner of a component, including a fixed seat 30 on one side of a concrete component 10. A corner guard 20 is provided at the external corner of the concrete component 10. Movable plates 40 are slidably connected to both ends of the fixed seat 30 near the concrete component 10. A moving component 50 is fixedly installed on the fixed seat 30. The moving component 50 is used to drive the two movable plates 40 to move towards the concrete component 10. A clamping component 60 is provided on the movable plate 40. The moving component 50 drives the clamping component 60 to press against the corner guard 20. A groove 31 is opened on the side of the fixed seat 30 facing the concrete component 10. The moving component 50 includes a bidirectional lead screw 51, a reduction motor 52, and a movable block 53. The bidirectional lead screw 51 is rotatably connected to the inside of the groove 31. The reduction motor 52 is installed on one side of the fixed seat 30, and the output shaft of the reduction motor 52 extends into the inside of the groove 31 and is fixedly connected to the bidirectional lead screw 51. A battery is installed on the outside of the fixed seat 30. The battery box (not shown in the figure) contains a battery that is electrically connected to the geared motor 52 and drives the output shaft of the geared motor 52 to rotate. Two movable blocks 53 are fitted and threaded to both ends of the double-acting screw 51, and the two movable blocks 53 are fixed to the two movable plates 40 respectively. The movable blocks 53 are slidably disposed between the inner walls of the two sides of the groove 31. The output shaft of the movable blocks 53 can drive the double-acting screw 51 to rotate inside the groove 31, thereby driving the two movable blocks 53 at both ends to move towards each other. The inner walls of the two sides of the groove 31 limit the sliding of the movable blocks 53 to prevent the movable blocks 53 from rotating with the double-acting screw 51. The two movable blocks 53 can drive the two movable plates 40 to move to both sides of the corner protector 20, so as to facilitate the adjustment of the distance between the movable plates 40 and the clamping assembly 60 at any time according to the distance of the corner protector 20 on the concrete component 10, thereby providing auxiliary fixation for the corner protector 20 on concrete components 10 of different sizes and improving the applicability of the auxiliary device.
[0020] Please refer to Figures 1-4The clamping assembly 60 includes a pressure plate 61, insert rods 62, a spring 63, a fixing block 64, and rollers 65. The pressure plate 61 is located on the side of the movable plate 40 near the corner guard 20, and the pressure plate 61 is in contact with the corner guard 20 to press against the outside of the corner guard 20. The edge of the pressure plate 61 is aligned with the corner guard 20 to control the flatness of the plastering surface and prevent the pressure plate 61 from affecting the plastering work. Two insert rods 62 are symmetrically arranged on both sides of the pressure plate 61, and the two insert rods 62 are inserted and connected to the movable plate 40. The fixing block 64 is located at the end of the insert rod 62 away from the pressure plate 61 to prevent... The insert rod 62 is separated from the movable plate 40. The spring 63 is sleeved on the outside of the insert rod 62. The spring 63 is located between the pressure plate 61 and the movable plate 40. When the movable plate 40 moves towards the corner protector 20, the movable plate 40 causes the pressure plate 61 to come into contact with the corner protector 20. The spring 63 can be compressed as the movable plate 40 moves. The pressure generated by the elastic force of the spring 63 can press the pressure plate 61 tightly against the outside of the corner protector 20, thereby fixing the corner protector 20 to the concrete component 10. This prevents the corner protector 20 from moving at will, which is beneficial for controlling the lines at the external corner and determining the plaster thickness.
[0021] Please refer to Figures 1-4 The pressure plate 61 has a through groove 611 in the middle, and the roller 65 is set inside the through groove 611. One side of the roller 65 contacts the outer side of the corner guard 20. Through the roller 65 inside the through groove 611 that contacts the corner guard 20, the sliding friction between the pressure plate 61 and the corner guard 20 can be changed into rolling friction. After the spring force of the spring 63 is slightly reduced, the pressure plate 61 can slide on the corner guard 20 by the rolling of the roller 65, thereby changing the position of the fixing seat 30 on the outer side of the concrete component 10. When the plaster is applied by hand to the position of the fixing seat 30, the position of the fixing seat 30 can be adjusted so that the fixing seat 30 will not block the plastering position, so that the setting of the auxiliary device will not prevent the operation of the hand when plastering.
[0022] The functional principle of this application can be explained through the following methods:
[0023] In use, the fixing base 30 is placed on one side of the top of the concrete component 10. The reduction motor 52 is started, and the battery supplies power to the reduction motor 52, causing the output shaft of the reduction motor 52 to drive the bidirectional lead screw 51 inside the groove 31 to rotate. The rotation of the bidirectional lead screw 51 causes the movable blocks 53, which are threaded to both ends, to move towards each other, thereby driving the movable plate 40 to move towards each other to a suitable position according to the distance between the two corner protectors 20. The movement of the movable plate 40 causes the pressure plate 61 to move towards the corner protectors 20 and contact them. The continued movement of the movable plate 40 can cause the movable plate 40 to move towards the corner protectors 20. The distance between the 0 and the pressure plate 61 is shortened, which compresses the spring 63 on the outside of the insert rod 62. The elastic force of the spring 63 causes the pressure plate 61 to tend to move towards the corner protector 20, so that the pressure plate 61 is pressed tightly on the outside of the corner protector 20, preventing the corner protector 20 from moving at will. This facilitates the protection of the lines at the external corner from being damaged and makes the plaster thickness clear. Another fixing seat 30 is installed at the bottom of the two corner protectors 20 to clamp and fix the two corner protectors 20. The movement of the two movable plates 40 allows the auxiliary device to be freely adjusted in size, so that plastering work can be carried out on components of various sizes.
[0024] When plastering the concrete component 10 between the two corner protectors 20, the hand will move between the two corner protectors 20. When the fixed seat 30 blocks the hand from plastering, the reduction motor 52 is started, causing the reduction motor 52 to reverse, causing the two movable plates 40 to move outward a certain distance, reducing the elastic force of the spring 63. At this time, the pressure plate 61 still limits the corner protector 20, so that the pressure plate 61 can be driven to move on the corner protector 20 by the rolling of the roller 65 inside the through groove 611, thereby changing the position of the fixed seat 30, so that the fixing of the corner protector 20 by the fixed seat 30 will not hinder the plastering operation of the concrete component 10. After plastering one side of the concrete component 10 is completed, the two corner protectors 20 and the auxiliary device can be moved to the other side of the concrete component 10 to perform plastering work on different sides of the concrete component 10.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
