Description

Technical Field

[0001] The utility model mainly relates to the technical field of engineering construction tools, and specifically relates to an interleaved type engineering construction protective frame body. Background Technique

[0002] During engineering construction, in order to prevent non-construction personnel from accidentally breaking in and ensure that construction personnel can carry out construction operations better, it is necessary to set up a protective frame to provide protection and warning for the construction area. However, for the existing protective frames, when they are installed and used in different sections, due to the undulating road conditions in different sections, the installation of the protective frames is uneven in height, thus reducing the protection effect; and when setting up the protective frames in sections with obstacles, the adjacent two protective frames need to be bent to avoid the obstacles, and the bending angle is not easy to control, and it is necessary to manually measure with external measuring tools, which is inconvenient to use. Content of the Utility Model

[0003] The purpose of the utility model is to provide an interleaved type engineering construction protective frame body to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: an interleaved type engineering construction protective frame body, including a main frame body, an adjusting frame body is slidably arranged in the main frame body, a rack and a gear that mesh with each other are arranged in the adjusting frame body, a height adjusting handle is inserted on the main frame body, the height adjusting handle is fixedly connected with the gear, and an upper connecting structure and a lower connecting structure are respectively arranged in an interleaved manner on both sides of the main frame body.

[0005] Preferably, the upper connecting structure includes a shell and a limiting member. The shell is a cylindrical shell with a top cover, the limiting member is embedded on the side wall of the shell, an arc-shaped protrusion is formed inside the limiting member, and a handle slot is formed at the top of the shell.

[0006] Further, the lower connecting structure includes a base, a cushion block, a limiting rotating plate and a circumferential adjusting handle. The cushion block is fixed on the base, the limiting rotating plate is fixed on the cushion block, the cushion block and the limiting rotating plate are cylindrical structures with a diameter not exceeding the inner diameter of the shell. Wave-shaped grooves that fit with the limiting member are formed in a circumferential array on the outer wall of the limiting rotating plate, the circumferential adjusting handle is fixed on the limiting rotating plate, and the handle end of the circumferential adjusting handle fits with the handle slot. The single rotation amplitude of the lower connecting structure relative to the upper connecting structure is restricted by the clamping connection between the limiting rotating plate and the limiting member.

[0007] Furthermore, a plurality of first screw holes are evenly formed in a circumferential array at the top of the shell, and a first bolt that fits with the first screw holes is inserted on the circumferential adjusting handle. The rotation of the circumferential adjusting handle relative to the upper connecting structure is restricted by the connection between the first screw holes and the first bolts.

[0008] Preferably, cross beams are arranged on the outer side walls on both sides of the main frame body. Connecting columns are fixed on any one of the cross beams. A fixing sleeve is sleeved on any one of the connecting columns. Connecting bars are fixed on the outer wall of the fixing sleeve. The connecting bars on both sides are staggered with each other along the direction of the connecting column. The connecting bars on both sides are respectively fixed to the upper connecting structure and the lower connecting structure. The upper connecting structure and the lower connecting structure are staggered and fixed on both sides of the main frame body through the connecting bars.

[0009] Preferably, a first accommodation cavity is formed on the main frame body. The adjusting frame body is located in the first accommodation cavity. A second accommodation cavity is formed on the adjusting frame body. The rack and the gear are located in the second accommodation cavity. The rack is fixedly connected to the inner wall of the second accommodation cavity. The handle rod of the height adjusting handle sequentially penetrates into the first accommodation cavity and the second accommodation cavity and is fixedly connected to the center of the gear. The gear is driven to rotate by the height adjusting handle to engage with the rack.

[0010] Preferably, a second bolt is inserted into the handle end of the height adjusting handle. A plurality of second screw holes are equidistantly formed on the outer wall of the main frame body along the rotation path of the second bolt. The connection between the second screw holes and the second bolt is used to limit the relative rotation of the height adjusting handle with respect to the main frame body.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The gear is driven to rotate by the height adjusting handle. The rack slides in the height direction under the engagement of the gear, so as to drive the adjusting frame body to slide and adjust in the height direction relative to the main frame body, so as to realize the equal height setting of adjacent protective frames in undulating sections;

[0013] The adjacent protective frames are conveniently assembled through the upper connecting structure and the lower connecting structure staggered on both sides of the main frame body. When the adjacent main frame bodies are bent and flipped, the lower connecting structure rotates relative to the upper connecting structure, and at the same time, the limiting member rotates relative to the limiting rotating plate. During the rotation of the limiting member, its arc-shaped protrusion tightly abuts against the wavy groove of the limiting rotating plate, so that a periodic resistance is generated during the rotation process, so as to limit the single rotation angle between adjacent main frame bodies to a fixed value without manual measurement.

An adjusting framework 2 is slidably arranged inside the main framework 1. Inside the adjusting framework 2, there are a rack 13 and a gear 14 that mesh with each other. A height-adjusting handle 9 is inserted on the main framework 1, and the height-adjusting handle 9 is fixedly connected to the gear 14. On the outer side walls on both sides of the main framework 1, two cross beams 3 are respectively arranged. A connecting column 4 is fixed between the two cross beams 3 on any one side. Two fixing sleeves 5 are sleeved on any one of the connecting columns 4. A connecting strip 6 is fixed on the outer wall of any one of the fixing sleeves 5. There are a total of four connecting strips 6 on both sides. The two connecting strips 6 on the left are respectively connected to an upper connecting structure 7, and the two connecting strips 6 on the right are respectively connected to a lower connecting structure 8. The upper connecting structure 7 and the lower connecting structure 8 that are closer to each other are staggered with each other in the height direction. Two support seats 10 are arranged at the bottom of the main framework 1.

[0027] The upper connecting structure 7 includes a housing 23 and a limiting member 24. The housing 23 is a cylindrical housing with a lid on the top. The limiting member 24 is embedded on the side wall of the housing 23. An arc-shaped protrusion is formed inside the limiting member 24. A handle slot 25 is formed on the top of the housing 23. The lower connecting structure 8 includes a base 18, a cushion block 19, a limiting rotating plate 20 and a circumferential adjusting handle 21. The cushion block 19 is fixed on the base 18, and the limiting rotating plate 20 is fixed on the cushion block 19. The cushion block 19 and the limiting rotating plate 20 are cylindrical structures with a diameter and length not exceeding the inner diameter of the housing 23. Wave-shaped grooves that match the limiting member 24 are formed in a circumferential array on the outer wall of the limiting rotating plate 20. The circumferential adjusting handle 21 is fixed on the limiting rotating plate 20. The handle end of the circumferential adjusting handle 21 matches the handle slot 25, and the handle end of the circumferential adjusting handle 21 tightly abuts against the top outer wall of the housing 23, and at the same time, the top of the base 18 tightly abuts against the bottom outer wall of the housing 23 to prevent the lower connecting structure 8 from disengaging from the upper connecting structure 7 in the height direction.

[0028] A plurality of first screw holes 26 are evenly formed in a circumferential array on the top of the housing 23. The position of any one of the first screw holes 26 corresponds to the position of the wave-shaped groove of the limiting rotating plate 20. A first bolt 22 that matches the first screw hole 26 is inserted on the circumferential adjusting handle 21.

[0029] A first cavity 11 is formed on the main frame body 1. The adjusting frame body 2 is located within the first cavity 11. A second cavity 12 is formed on the adjusting frame body 2. The rack 13 and the gear 14 are located within the second cavity 12. The rack 13 is fixedly connected to the inner wall of the second cavity 12. The handle rod of the height adjusting handle 9 sequentially penetrates through the first cavity 11 and the second cavity 12 and is fixedly connected to the center of the gear 14. An activity window 15 is formed on one side of the second cavity 12 facing the height adjusting handle 9. When the rack 13 and the gear 14 mesh to drive the adjusting frame body 2 to slide in the height direction, the handle rod of the height adjusting handle 9 remains connected to the gear 14 through the activity window 15. A second bolt 16 is inserted into the handle end of the height adjusting handle 9. A plurality of second screw holes 17 are formed on the outer wall of the main frame body 1 at equal intervals along the rotation path of the second bolt 16. The second bolt 16 is connected to the second screw holes 17 to limit the height direction sliding adjustment of the adjusting frame body 2 relative to the main frame body 1.

[0030] The implementation principle of the embodiment of the present application is as follows: When this product is used, multiple products need to be assembled and spliced according to the site range. First, align the upper connection structure 7 of one product with the lower connection structure 8 of another product and insert them in a staggered manner. According to the obstacles in the site, overcome the resistance between the limit rotating plate 20 and the limiting member 24 to adjust the rotation amplitude between the upper connection structure 7 and the lower connection structure 8. The rotation angle can be known according to the number of times of overcoming the resistance, without manual measurement. After adjusting the angle, thread the first bolt 22 and the first screw hole 26 to complete the reinforcement. Subsequently, rotate the height adjusting handle 9 on one main frame body 1 according to the road conditions, so that the connected gear 14 meshes with the rack 13, driving the corresponding adjusting frame body 2 to adjust the height until it is aligned with the adjusting frame body 2 of another product. Then repeat the above process to complete the assembly and adjustment of multiple products.
