Description

Technical Field

[0001] The utility model relates to the technical field of calligraphy and painting frame processing, in particular to a calligraphy and painting frame splicing and shaping device which is easy to position. Background Art

[0002] In the process of mounting calligraphy and painting, it is necessary to position the calligraphy and painting paper through a calligraphy and painting frame to facilitate the installation of calligraphy and painting. The calligraphy and painting frame is generally spliced ​​by four frame strips with 45° angles at both ends, and the adjacent frame strips are fixed by glue or nails. The existing calligraphy and painting frame splicing is mainly achieved by manual positioning, and this positioning method is relatively inefficient. Therefore, in view of the above problems, a calligraphy and painting frame splicing shaping device that is easy to position is designed to better meet actual use needs. Utility Model Content

[0003] The purpose of the utility model is to provide a book and picture frame splicing and shaping device which is easy to position, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a book and painting frame splicing and shaping device that is easy to position, comprising an inner support plate, a fixing block with a right-angle structure is fixed on the upper end of the inner support plate, a threaded rod is connected to the bearing on the fixing block, an outer bracket with a right-angle structure is arranged on the outer side of the inner support plate, a positioning splint is arranged between the outer bracket and the inner support plate, and a frame strip is placed between the positioning splint and the inner support plate.

[0005] Preferably, a rotating wheel is fixed on the threaded rod, and the surface of the rotating wheel is a rough structure. The rough structure of the rotating wheel surface can increase the friction of the rotating wheel surface, thereby facilitating the rotation of the threaded rod.

[0006] Preferably, a connecting block is fixed to the upper end of the outer bracket, and the connecting block and the threaded rod are threadedly connected. The threaded connection between the connecting block and the threaded rod can provide basic guarantee for the position adjustment of the outer bracket.

[0007] Preferably, two positioning clamps are arranged on the side of the outer bracket, and the two positioning clamps are vertically distributed, and a sliding rod is fixed on one side of the positioning clamp close to the outer bracket, through the role of the positioning clamp.

[0008] Preferably, a rolling ball is installed on the side of the positioning clamp plate away from the outer bracket, and the ball can roll by contacting the outer wall of the frame bar. One end of a spring is fixed to the side of the positioning clamp plate close to the outer bracket, and the other end of the spring is fixed to the outer bracket. The frame bar can be conveniently positioned and clamped through the rolling action between the ball and the frame bar. In combination with the action of the spring, a force can be provided for the positioning clamp plate and the ball to ensure the positioning and clamping effect of the frame bar.

[0009] Preferably, the slide rod and the outer bracket are slidably connected, and a limiting ring is fixed on the slide rod, and the limiting ring contacts the outer bracket to achieve a limiting effect. The sliding guiding effect between the slide rod and the outer bracket can ensure the stability of the movement of the positioning clamping plate, and the moving distance of the slide rod and the positioning clamping plate can be limited by cooperating with the action of the limiting ring.

[0010] Compared with the prior art, the beneficial effects of the utility model are: the book and painting frame splicing and shaping device which is easy to position adopts an adjustable clamping and positioning mechanism, which can adapt to frame strips of different sizes for installation and fixation, and cooperates with the elastic mechanism, which can not only avoid the frame strips being damaged due to excessive force during the clamping and positioning process, but also can continuously provide force to the frame strips through the spring to ensure the bonding effect of adjacent frame strips, and cooperate with the internal and external positioning mechanisms to effectively ensure the neatness of the frame strip docking, thereby greatly improving the assembly efficiency of the book and painting frames.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-Figure 3 The utility model provides a technical solution: a book and painting frame splicing and shaping device that is easy to position, comprising an inner support plate 1, a fixing block 2 with a right-angle structure is fixed to the upper end of the inner support plate 1, a threaded rod 3 is connected to the bearing on the fixing block 2, an outer bracket 4 with a right-angle structure is arranged on the outer side of the inner support plate 1, a positioning splint 5 is arranged between the outer bracket 4 and the inner support plate 1, and a frame strip 7 is placed between the positioning splint 5 and the inner support plate 1.

[0017] A rotating wheel 301 is also fixed on the threaded rod 3, and the surface of the rotating wheel 301 is a rough structure; a connecting block 401 is fixed on the upper end of the outer bracket 4, and the connecting block 401 and the threaded rod 3 are threadedly connected; two positioning splints 5 are arranged on the side of the outer bracket 4, and the two positioning splints 5 are vertically distributed, and a sliding rod 6 is fixed on the side of the positioning splint 5 close to the outer bracket 4; a rolling ball 501 is installed on the side of the positioning splint 5 away from the outer bracket 4, and the ball 501 contacts the outer wall of the frame bar 7 for rolling, and one end of the spring 502 is fixed on the side of the positioning splint 5 close to the outer bracket 4, and the other end of the spring 502 is fixed on the outer bracket 4; the sliding rod 6 and the outer bracket 4 are slidably connected, and a limiting ring 601 is also fixed on the sliding rod 6, and the limiting ring 601 contacts the outer bracket 4 to achieve a limiting effect;

[0018] When using the book and picture frame splicing shaping device which is easy to position, Figure 1-Figure 3 As shown, first, the device is placed on a horizontal surface, and glue is applied to the two ends of the frame strips 7 at a 45° angle, and then the two frame strips 7 are brought into contact with the inner support plate 1, so that the adjacent 45° angles of the two frame strips 7 are accurately fitted and bonded. At this time, the frame strip 7 is located between the positioning clamp plate 5 and the inner support plate 1, and then the rotating wheel 301 is rotated to drive the threaded rod 3 to rotate, and the threaded connection between the threaded rod 3 and the connecting block 401 can be used to force the outer bracket 4 to move, thereby adjusting the distance between the positioning clamp plate 5 and the inner support plate 1. When the ball 501 on the positioning clamp plate 5 contacts the frame strip 7, the threaded rod 3 is continued to be rotated. At this time, the ball 501 rolls on the frame strip 7, and the positioning clamp plate 5 is synchronously forced to move toward the outer bracket 4, thereby reducing the distance between the outer bracket 4 and the inner support plate 1. The distance between the positioning splints 5, and the spring 502 is forced to contract at this time. When the positioning splint 5 moves, the sliding guiding effect between the slide rod 6 and the outer bracket 4 can ensure the stability of the movement of the positioning splint 5 until the limit ring 601 contacts the outer bracket 4 to achieve positioning, thereby realizing the positioning of the positioning splint 5. At this time, through the elastic effect of the spring 502, the positioning splint 5 and the ball 501 can be continuously provided with a force to achieve the clamping and positioning effect of the frame strip 7, thereby ensuring the stability of the bonding of the two frame strips 7. According to the above principle, the splicing angles of the four frame strips 7 are fixed by four positioning devices to achieve the splicing and shaping effect of the entire calligraphy and painting frame. This is the working principle of the splicing and shaping device for calligraphy and painting frames that is easy to position.
