Description

Technical Field

[0001] The invention relates to the technical field of building decoration engineering, in particular to a hammer-knocking type white wall plastering device for indoor decoration. Background Art

[0002] Before applying latex paint to indoor walls, it is necessary to scrape the white wall surface with a scraping device to facilitate the subsequent latex paint construction. Scraping is to scrape off the original plaster surface layer as a whole. It is a construction method of scraping and plastering the whole wall surface. The scraping device is usually called a scraper, and the blade at the end is used to scrape off the white lime on the wall surface. At present, CN202210837261.3 in the prior art discloses a hammer-knocking ash scraping device, which drives a rotating shaft and a toggle blade to rotate through the rotation of a driving motor. A rotating rod is also connected between the two sides of the inner wall of the ash scraping box, and a seesaw is rotatably connected to the surface of the rotating rod. When the toggle blade rotates, the end of the seesaw close to the toggle blade is driven to rotate. A plurality of knocking blocks are installed at the end of the seesaw away from the toggle blade. A fixed plate is connected to the top of the ash scraping box, and the bottom end of the fixed plate is connected to the seesaw through a plurality of springs. The height of one end of the seesaw provided with a knocking block is greater than the end of the seesaw close to the toggle blade, and the height of the top of the knocking block is greater than the height of the top of the ash scraping box, thereby improving the efficiency of removing white lime from the wall and facilitating operation. The technical revelation of the shoveling device found that the current shoveling device can only scrape the white lime on the wall with a blade, and cannot further hammer the white lime on the wall during the shoveling process to assist in the rapid scraping of the white lime. The comparative document adds a motor to hammer the white lime on the wall during the scraping process, resulting in the shoveling device being unable to use the extrusion force generated during the manual shoveling process to repeatedly hammer the wall. The present invention can mainly solve the problem that the plaster scraping device cannot utilize the squeezing force generated in the manual plaster scraping process, resulting in repeated hammering of the wall. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a hammer-knocking white wall plastering device for indoor decoration to solve the problems described in the above background technology.

[0004] The purpose and effect of the hammer-knocking white wall plastering device for interior decoration of the present invention are achieved by the following specific technical means: a hammer-knocking white wall plastering device for interior decoration, comprising a handle, a blade is installed at the end of the handle, and slide grooves are opened on both sides of the blade, and the slide grooves are arranged in an arc shape.

[0005] Furthermore, the handle is a long handle.

[0006] Furthermore, the arc angle of the sliding groove of the blade is 120°, and a rotating shaft is hinged on both sides of the blade, and the rotating shaft is located at the end of the blade away from the handle.

[0007] Furthermore, one end of the rotating shaft away from the handle is swingably connected to a shaft arm, and the other end of the rotating shaft is swingably connected to a swing arm. A cross bar is provided on the side of the swing arm away from the rotating shaft, and a clamping column is slidably connected to the inner side of the sliding groove of the blade, and the clamping column slides through the inner side of the swing arm.

[0008] Furthermore, the shaft arm extends to the outside of the blade, and the shaft arm is linked to the swing arm through a rotating shaft, and the weight of the shaft arm is 50-100g greater than the weight of the swing arm.

[0009] Furthermore, a groove is passed through the inner side of the swing arm, and the clamping column slides through the inner side of the groove. The swing arm tilts and swings on one side of the blade through the clamping column, and the swing angle is less than 120°.

[0010] Furthermore, bases are provided on both sides of the blade close to the crossbar, one end of the base is rotatably nested and connected with a universal ball, and one end of the universal ball away from the base is slidably connected with a hammering disk.

[0011] Furthermore, the interior of the base is hollow, the universal ball is slidably nested and connected to one side of the base while rotating, and the universal ball and the cross bar are arranged in the same horizontal plane.

[0012] Furthermore, the hammering disk is in the shape of a disk, and a plurality of cones are arranged on the surface of the hammering disk. The side of the hammering disk away from the universal ball slides and strikes the wall surface.

[0013] Furthermore, an inclined plate surrounds the interior of the base, a slider is slidably connected to the inner side of the inclined plate, an end of the slider close to the universal ball is elastically connected to a spring, and an end of the spring close to the universal ball is elastically connected to a disc.

[0014] Furthermore, the inclined plate is inclined at 45 degrees, and the slider, spring and disc are matched with the inclined plate, and the disc is elastically fitted to the end of the universal ball away from the hammering disc.

[0015] Furthermore, the disc is fitted around one end of the universal ball, the spring is inclined at 25-45 degrees, and the spring and the disc slide on one side of the inclined plate through a slider.

[0016] Beneficial effects: 1. One end of the blade scrapes away the white lime on the wall surface. Since the shaft arm extends to the outside of the blade, when the blade scrapes away the wall surface, the wall surface is squeezed to one side of the shaft arm. The shaft arm drives the swing arm to swing obliquely through the rotating shaft. When swinging, the clamping column slides synchronously with the inner side of the blade's slide groove. The arc angle of the blade's slide groove is 120°, and the clamping column is inside the slide groove, so that the swing arm swings obliquely on one side of the blade through the clamping column, and the swing angle is less than or equal to 120°; 2. The universal ball and the crossbar are arranged in the same horizontal plane. When the swing arm drives the crossbar to swing obliquely, the crossbar can be squeezed to one side of the universal ball, so that the universal ball can rotate obliquely at one end of the base, and the universal ball drives the hammer plate to rotate synchronously; 3. Since the weight of the shaft arm is 50-100g greater than that of the swing arm, after the shaft arm drives the swing arm to tilt and swing, the shaft arm can quickly return to its original position by its own weight. Therefore, after the blade removes the lime from the wall once, the shaft arm can return to its original position and swing through the rotating shaft. The blade removes the lime from the wall again, and the shaft arm can tilt and swing again due to the pressure of the wall surface on one side of the rotating shaft, and the above steps can be repeated; 4. The disc is wrapped around and fitted to one end of the universal ball. When the universal ball is tilted and swung due to the extrusion of the crossbar, the side of the end of the universal ball is squeezed to the end of the disc on the inner side of the base. The disc on one side of the base can be squeezed to the end of the matching spring. The spring and the disc can slide on the inner side of the inclined plate through the slider. At this time, one side of the end of the universal ball loses support, which facilitates the universal ball to slide briefly toward the inner side of the base as a whole. The universal ball drives the hammer disc to slide toward one end of the base synchronously; 5. By utilizing the inclined setting of the inclined plate and the resilience of the spring, the slider can slide back inside the base, and the slider drives the spring and the disc as a whole to slide toward one end of the universal ball. By utilizing the return extrusion of the disc, the universal ball can drive the hammering disc to slide toward the end away from the blade again. At this time, the hammering disc can hammer onto the wall surface. Repeat the above steps. The hammering disc can utilize the extrusion force of the wall surface when the blade removes the white lime to drive the cross bar to be squeezed to the end of the universal ball, and then drive the hammering disc to hammer-knock the wall surface through the above steps, without the need for electronic components to assist in hammering.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0027] As attached Figure 1 To Attachment Figure 8 As shown: Embodiment 1: A hammer-type white wall plaster scraping device for interior decoration, comprising a handle 1, a blade 101 is installed at the end of the handle 1, and slide grooves are provided on both sides of the blade 101, and the slide grooves are arranged in an arc shape; Wherein: handle 1, handle 1 is set with a long handle; The blade 101 has a sliding groove with an arc angle of 120°. Both sides of the blade 101 are hinged with a rotating shaft 2, and the rotating shaft 2 is located at the end of the blade 101 away from the handle 1; Wherein: the worker holds the handle 1 and removes the white ash on the wall surface through the blade 101 at the end of the handle 1; Example 2: Refer to the attached manual Figure 1-5 It can be seen that the difference between Example 2 and Example 1 is that the end of the rotating shaft 2 away from the handle 1 is swingably connected to the shaft arm 201, and the other end of the rotating shaft 2 is swingably connected to the swing arm 202. The side of the swing arm 202 away from the rotating shaft 2 is provided with a cross bar 203, and the inner side of the sliding groove of the blade 101 is slidably connected to a clamping column 204, and the clamping column 204 slides through the inner side of the swing arm 202; Wherein: the shaft arm 201, the shaft arm 201 extends to the outside of the blade 101, the shaft arm 201 is in linkage with the swing arm 202 through the rotating shaft 2, and the weight of the shaft arm 201 is 50-100g greater than the weight of the swing arm 202; The weight of the shaft arm 201 is 50-100g greater than that of the swing arm 202. After the shaft arm 201 drives the swing arm 202 to tilt and swing, the shaft arm 201 can quickly return to its original position by its own weight. The swing arm 202 has a groove running through the inner side thereof, and the clamping column 204 slides through the inner side of the groove. The swing arm 202 tilts and swings on one side of the blade 101 through the clamping column 204, and the swing angle is less than 120°; The arc angle of the slide groove of the blade 101 is 120°, and the clamping column 204 is inside the slide groove, so that the swing arm 202 swings at a side of the blade 101 through the clamping column 204, and the swing angle is less than or equal to 120°. Figure 4 As shown; Wherein: one end of the blade 101 scrapes off the white lime on the wall surface. Since the shaft arm 201 extends to the outside of the blade 101, when the blade 101 scrapes off the wall surface, the wall surface is squeezed to one side of the shaft arm 201. The shaft arm 201 drives the swing arm 202 to swing obliquely through the rotating shaft 2. When the swing arm 202 swings, the clamping column 204 slides synchronously with the inner side of the slide groove of the blade 101. The arc angle of the slide groove of the blade 101 is 120°, and the clamping column 204 is inside the slide groove, so that the swing arm 202 swings obliquely on one side of the blade 101 through the clamping column 204, and the swing angle is less than or equal to 120°; Example 3: Refer to the attached manual Figure 1-6 It can be seen that the difference between Example 3 and Example 1-2 is that a base 3 is provided on both sides of the blade 101 close to the crossbar 203, one end of the base 3 is rotatably nested and connected with a universal ball 301, and the end of the universal ball 301 away from the base 3 is slidably connected with a hammering disc 302; Among them: the base 3 and the universal ball 301, the interior of the base 3 is hollow, the universal ball 301 is connected to one side of the base 3 in a sliding nested manner and rotates at the same time, and the universal ball 301 and the crossbar 203 are arranged in the same horizontal plane; The universal ball 301 and the cross bar 203 are arranged in the same horizontal plane. When the cross bar 203 is tilted and swung, the cross bar 203 can be squeezed to one side of the universal ball 301, so that the universal ball 301 can be tilted and rotated at one end of the base 3; The hammering plate 302 is in the shape of a disk, and a plurality of cones are provided on the surface of the hammering plate 302. The side of the hammering plate 302 away from the universal ball 301 slides and strikes the wall surface; The universal ball 301 and the cross bar 203 are arranged on the same horizontal plane. When the swing arm 202 drives the cross bar 203 to swing obliquely, the cross bar 203 can be squeezed to one side of the universal ball 301, so that the universal ball 301 can rotate obliquely at one end of the base 3, and the universal ball 301 drives the hammering plate 302 to rotate obliquely synchronously. Since the weight of the shaft arm 201 is 50-100g greater than that of the swing arm 202, after the shaft arm 201 drives the swing arm 202 to tilt and swing, the shaft arm 201 can quickly return to its original position by using its own weight. Therefore, after the blade 101 removes the lime from the wall once, the shaft arm 201 can return to its original position and swing through the rotating shaft 2. The blade 101 removes the lime from the wall again, and the shaft arm 201 can tilt and swing again due to the pressure of the wall surface on one side of the rotating shaft 2, and the above steps can be repeated. Example 4: Refer to the attached manual Figure 6-8 It can be seen that the difference between Example 4 and Examples 1-3 is that the base 3 is surrounded by an inclined plate 4, the inner side of the inclined plate 4 is slidably connected to a slider 401, the end of the slider 401 close to the universal ball 301 is elastically connected to a spring 402, and the end of the spring 402 close to the universal ball 301 is elastically connected to a disc 403; Wherein: the inclined plate 4 is inclined at 45 degrees, the slider 401, the spring 402 and the disc 403 are matched with the inclined plate 4, and the disc 403 is elastically attached to the end of the universal ball 301 away from the hammering disc 302; When the spring 402 and the disc 403 at one end of the slider 401 are not squeezed, the slider 401 is at the lower end of the inclined surface of the inclined plate 4. Figure 8 As shown; The inclined plate 4 is inclined at 45 degrees. The inclined setting of the inclined plate 4 facilitates the slider 401 to drive the spring 402 and the disc 403 to slide on the inner side of the base 3. The spring 402 and the disc 403 slide as a whole, so that the universal ball 301 is conveniently connected to one end of the base 3 in a sliding nested manner. The slider 401, the spring 402 and the disc 403 are attached to one end of the universal ball 301, the spring 402 is inclined at 25-45 degrees, and the spring 402 and the disc 403 slide on one side of the inclined plate 4 through the slider 401; The disc 403 is wrapped around and fitted to one end of the universal ball 301. When the universal ball 301 is squeezed by the cross bar 203 and tilted and swung, the side of the end of the universal ball 301 is squeezed to the end of the disc 403 on one side of the base 3. The disc 403 on one side of the base 3 can be squeezed to the end of the matching spring 402. The spring 402 and the disc 403 can slide on the inner side of the inclined plate 4 through the slider 401. At this time, one side of the end of the universal ball 301 loses support, which facilitates the universal ball 301 to slide briefly toward the inner side of the base 3 as a whole. The universal ball 301 drives the hammering disc 302 to slide toward one end of the base 3 synchronously. By utilizing the inclined setting of the inclined plate 4 and the resilience of the spring 402, the slider 401 can slide back inside the base 3, and the slider 401 drives the spring 402 and the disc 403 to slide as a whole toward one end of the universal ball 301. By utilizing the return and extrusion of the disc 403, the universal ball 301 can drive the hammering disk 302 to slide back toward the end away from the blade 101. At this time, the hammering disk 302 can hammer onto the wall surface, and the above steps are repeated. The hammering disk 302 can utilize the extrusion force of the wall surface when the blade 101 removes the white lime to drive the cross bar 203 to be squeezed to the end of the universal ball 301, and then through the above steps, the hammering disk 302 is driven to hammer-knock the wall surface, without the need for electronic components to assist in hammering.
