Description

Technical Field

[0001] The present invention relates to the field of children's amusement facilities, and particularly to a fence railing for a children's playground and its processing tooling. Background Art

[0002] Some amusement facilities in children's playgrounds need to be enclosed by fences for safety. Currently, the structures of all fences are roughly as shown in the patent publication document CN304038666S. The railings of this type of fence are generally cylindrical, and the railings are generally made of hard plastic. The fence surrounded by railings of this structure has good protective performance. When an external object hits the fence, these hard railings can block the external object from hitting the equipment in the playground. However, there is also a problem in the actual use of this type of fence, that is, since this type of fence is made of hard plastic and the renewal cycle of the fence is generally relatively fast, for cost considerations, many fences are directly spliced with UPVC plastic pipes. Although this hard plastic (UPVC) ensures the rigidity of the entire fence, it also poses a safety hazard to the children playing. First, when a child hits these hard railings, it will cause greater pain to the child; second, since the brittleness of this type of railing is relatively large, when the impact force is relatively large, the railing is easy to break and generate fragments, thus endangering personal safety. Summary of the Invention

[0003] The present invention aims at the above problems and provides a fence railing for a children's playground and its processing tooling.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A fence railing for a children's playground includes a pipe body and elastic strips. The pipe body is a pipe body made of UPVC material, and the pipe body is a circular pipe body. A notch is opened on the pipe wall of the pipe body. The elastic strips are arranged in the notch, and the elastic strips are in a state of being crisscrossed and connected, and a part of each elastic strip is exposed outside the pipe body. The elastic strips are TPU elastic strips.

[0006] In this kind of fence railing, on the basis of the original UPVC pipe, a gap is further opened, and elastic strips of TPU material are arranged in the gap. The elastic strips are cross-linked together, and it is ensured that a part of each elastic strip is exposed outside the pipe body, so that when the player accidentally collides with the fence, there is a greater probability of hitting the elastic strip, and hitting the elastic strip can reduce the pain caused to the player. At the same time, since the elastic strips staggered and connected on the pipe body play a role similar to a reinforcement net, the presence of the elastic strips increases the toughness of the entire pipe body, which can reduce the probability of the pipe body breaking. Even if the impact intensity is large and the pipe body is broken, due to the criss-crossing elastic strips, and the elastic strips are bonded to the pipe wall of the pipe body, the adhesion of the elastic strips can minimize the probability of fragments after the pipe body cracks, so that the pipe body can be broken without dispersing with the greatest probability, reducing the probability of fragments flying.

[0007] In summary, this type of fence railing increases the toughness of the entire tube body by arranging staggered elastic strips on the tube wall, reduces the probability of the tube body breaking when impacted, and reduces the probability of fragments flying when the tube body breaks due to impact.

[0008] Specifically in this kind of railing, part of the notches on the tube body are through-hole notches (ie, the notches penetrate the tube wall of the tube body), and the other part of the notches are slot notches (ie, the notches do not penetrate the tube wall of the tube body).

[0009] Optionally, the thickness of the elastic strip is greater than the wall thickness of the tube body.

[0010] A processing tool comprises a base, a clamping chuck assembly, a first motor and a top clamping block, wherein the clamping chuck assembly is rotatably arranged on the base, the first motor is arranged on the base, the first motor cooperates with the clamping chuck assembly, the top clamping block is rotatably arranged on the base, a lifting seat is slidably arranged on the base, a blade is arranged on the lifting seat, a guide slide seat is arranged on one side of the base, a manipulator is slidably installed on the guide slide seat, and an extrusion gun is installed on the manipulator.

[0011] In this processing tool, the clamping chuck assembly and the top clamping block on the base are used to clamp the pipe body. When the first motor is working, the first motor can drive the clamping chuck assembly to rotate relative to the base, thereby driving the entire pipe body to rotate. When the pipe body is clamped, the pipe body is in a parallel state with the base and the guide slide seat.

[0012] The specific lifting seat is located between the clamping chuck assembly and the top clamping block. The blade on the lifting seat can move up and down relative to the base. When the lifting seat moves up and down until the blade contacts the surface of the pipe body, and when the lifting seat moves between the clamping chuck assembly and the top clamping block, the blade can cut a notch on the pipe body. Therefore, the blade on the lifting seat can cut notches of different depths and lengths on the pipe body.

[0013] The guiding slide table seat is arranged on one side of the base, and the manipulator is slidably installed on the guiding slide table seat. Therefore, the manipulator can move on one side of the guiding slide table seat. When the manipulator moves on the guiding slide table, it moves along the pipe body. When the manipulator moves, it can extrude the hot-melt TPU glue to the notch of the pipe body as needed. After solidification, a TPU elastic strip is formed.

[0014] Optionally, the blade is a bullet-shaped blade. A second motor is installed on the lifting seat. The second motor is cooperated with the blade. A groove is opened on the wall surface at the pointed end of the blade.

[0015] With a bullet-shaped blade, the cylindrical end of the blade is cooperated with the second motor, and the pointed end of the blade contacts the pipe body. When the second motor rotates, the blade rotates to cut a notch on the pipe body. A groove is opened on the wall surface at the pointed end of the blade. Such a design is to ensure that when the blade cuts a notch on the pipe body, the cut notch is serrated and there are burrs at the cut. The serrated notch and the burrs at the notch can increase the adhesion connection strength between the TPU elastic strip and the pipe body, and reduce the probability of the TPU elastic strip falling off from the notch of the pipe body.

[0016] Optionally, the lifting seat includes a base table, a lifting table and a lifting rod. The base table is slidably installed on the base. The lifting rod is arranged on the base table. The lifting table is arranged on the lifting rod. The blade is arranged on the lifting table. A third motor is arranged on the base table. The third motor is cooperated with the rack on the base.

[0017] Specifically, the third motor on the base table is cooperated with the rack on the base through a gear. When the third motor rotates, the base table moves on the base under the action of the third motor. When the lifting rod moves up and down, the lifting table located on the lifting rod moves up and down, and the distance between the lifting table and the pipe body changes. When the lifting rod extends, the lifting table approaches the pipe body. When the lifting rod contracts, the distance between the lifting table and the pipe body increases.

[0018] Optionally, it further includes a first bearing platform and a second bearing platform. The first bearing platform is fixedly arranged on the base, the clamping chuck assembly is rotatably arranged on the first bearing platform, the second bearing platform is slidably arranged on the base, the top clamping block is rotatably arranged on the second bearing platform, and a fourth motor is arranged on the second bearing platform. The fourth motor is engaged with a rack on the base.

[0019] Specifically, a gear is installed on the fourth motor, and the gear on the fourth motor is engaged with the rack on the base. When the fourth motor operates, the second bearing platform moves on the base, and the distance between the first bearing platform and the second bearing platform changes accordingly, so that pipe bodies of different lengths are clamped between the first bearing platform and the second bearing platform.

[0020] Optionally, a guiding slide rail is arranged on the base, and the lifting seat is slidably engaged with the guiding slide rail.

[0021] Specifically, both the second bearing platform and the bottom platform of the lifting seat are slidably engaged with the guiding slide rail, and the second bearing platform and the bottom platform both move along the guiding slide rail on the base.

[0022] Optionally, a rack is arranged on the guiding slide block seat, and a fifth motor is arranged on the mechanical arm. The fifth motor is engaged with the rack on the guiding slide block seat.

[0023] A gear is installed on the shaft of the fifth motor, and the gear on the fifth motor is engaged with the rack on the guiding slide block seat. When the fifth motor operates, it drives the mechanical arm to move on the guiding slide block seat.

[0024] Optionally, the guiding slide block seat is in a parallel state with the base.

[0025] Optionally, the top clamping block is a conical top clamping block.

[0026] The conical top clamping block has a good top clamping effect on pipe bodies of different pipe diameters.

[0027] The beneficial effects of the present invention are: by arranging elastic strips that are staggered and connected on the pipe wall, the toughness of the entire pipe body is increased, the probability of the pipe body cracking when being impacted is reduced, and the probability of debris splashing when the pipe body cracks due to impact is reduced.

DETAILED DESCRIPTION

[0034] The present invention is described in detail below in conjunction with the accompanying drawings. Example

[0035] See attached Figure 5 As shown, a children's playground fence railing includes a tube body 18 and an elastic strip 19. The tube body 18 is a tube body 18 made of UPVC material, and the tube body 18 is a circular tube body 18. A notch is opened on the tube wall of the tube body 18. The elastic strip 19 is arranged in the notch, and the elastic strip 19 is in a criss-cross and connected state, and a part of each elastic strip 19 is exposed outside the tube body 18. The elastic strip 19 is a TPU elastic strip 19.

[0036] In this kind of fence railing, on the basis of the original UPVC pipe, a gap is further opened, and elastic strips 19 made of TPU material are arranged in the gap. The elastic strips 19 are cross-linked with each other, and it is ensured that a part of each elastic strip 19 is exposed outside the tube body 18, so that when the player accidentally collides with the fence, there is a greater probability of hitting the elastic strip 19, and hitting the elastic strip 19 can reduce the pain caused to the player. At the same time, since the elastic strips 19 staggered and connected on the tube body 18 play a role similar to a reinforcement net, the presence of the elastic strips 19 increases the toughness of the entire tube body 18, which can reduce the probability of the tube body 18 breaking. Even if the impact intensity is large and causes the tube body 18 to break, due to the criss-crossing elastic strips 19, and the elastic strips 19 are bonded to the tube wall of the tube body 18, the adhesion effect of the elastic strips 19 can reduce the probability of fragments after the tube body 18 cracks as much as possible, so that the tube body 18 can be broken without dispersing with the greatest probability, reducing the probability of fragments splashing.

[0037] In summary, by providing the elastic strips 19 that are staggered and connected on the pipe wall, the toughness of the entire pipe body 18 is increased, the probability of the pipe body 18 cracking when being impacted is reduced, and the probability of debris splashing when the pipe body 18 cracks due to impact is reduced.

[0038] Specifically, in this type of railing, a part of the notch on the pipe body 18 is a through-hole notch (i.e., the notch penetrates the pipe wall of the pipe body 18), while the other part of the notch is a groove notch (i.e., the notch does not penetrate the pipe wall of the pipe body 18).

[0039] As shown in the attached drawings, the thickness of the elastic strip 19 is greater than the thickness of the pipe wall of the pipe body 18.

[0040] The railing provided in this embodiment uses the existing mature UPVC pipe as the raw material. By means of grooving and adding elastic strips, the toughness and twistability of the pipe body are enhanced, ensuring that the pipe body is not prone to debris splashing when being impacted. Embodiment

[0041] A processing tooling for processing the railing as shown in Embodiment 1, as shown in the attached Figures 1 to 4 drawings, includes a base 8, a clamping chuck assembly 10, a first motor 12, and a top clamping block 6. The clamping chuck assembly 10 is rotatably arranged on the base 8. The first motor 12 is arranged on the base 8. The first motor 12 is cooperated with the clamping chuck assembly 10. The top clamping block 6 is rotatably arranged on the base 8. A lifting seat is slidably arranged on the base 8. A blade 17 is arranged on the lifting seat. A guiding sliding table seat 4 is arranged on one side of the base 8. A manipulator 3 is slidably installed on the guiding sliding table seat 4. An extrusion gun is installed on the manipulator 3.

[0042] In this type of processing tooling, the functions of the clamping chuck assembly 10 and the top clamping block 6 on the base 8 are to clamp the pipe body 18. When the first motor 12 works, the first motor 12 can drive the clamping chuck assembly 10 to rotate relative to the base 8, thereby driving the entire pipe body 18 to rotate. When the pipe body 18 is clamped, the pipe body 18 is in a parallel state with the base 8 and the guiding sliding table seat 4.

[0043] Specifically, the lifting seat is located between the clamping chuck assembly 10 and the top clamping block 6. The blade 17 on the lifting seat can move up and down relative to the base 8. When the lifting seat moves up and down until the blade 17 contacts the surface of the pipe body 18, and when the lifting seat moves between the clamping chuck assembly 10 and the top clamping block 6, the blade 17 can process notches on the pipe body 18. Therefore, the blade 17 on the lifting seat can process notches with different depths and lengths on the pipe body 18.

[0044] The guiding slide base is arranged on one side of the base 8, and the manipulator 3 is slidably mounted on the guiding slide base. Therefore, the manipulator 3 can move on one side of the guiding slide base. When the manipulator 3 moves on the guiding slide, it moves along the pipe body 18. When the manipulator 3 moves, it can extrude the molten TPU glue to the notch of the pipe body 18 as needed. After solidification, the TPU elastic strip 19 is formed.

[0045] As shown in the Figure 3 attachment, the blade 17 is a bullet-shaped blade 17. A second motor is installed on the lifting seat, and the second motor is engaged with the blade 17. A groove 1701 is formed on the wall surface at the pointed end of the blade 17.

[0046] By using the bullet-shaped blade 17, the cylindrical end of the blade 17 is engaged with the second motor, and the pointed end of the blade 17 contacts the pipe body 18. When the second motor rotates, the blade 17 rotates to process a notch on the pipe body 18. A groove 1701 is formed on the wall surface at the pointed end of the blade 17. Such a design is to ensure that when the blade 17 processes a notch on the pipe body 18, the processed notch is serrated and there are burrs at the processing opening. The serrated notch and the burrs at the notch can increase the adhesion connection strength between the TPU elastic strip 19 and the pipe body 18, and reduce the probability of the TPU elastic strip 19 falling off from the notch of the pipe body 18.

[0047] As shown in the Figure 1 and 2 attachment, the lifting seat includes a base 13, a lifting table 15 and a lifting rod 14. The base 13 is slidably mounted on the base 8. The lifting rod 14 is arranged on the base 13. The lifting table 15 is arranged on the lifting rod 14. The blade 17 is arranged on the lifting table 15. A third motor 16 is arranged on the base 13, and the third motor 16 is engaged with the rack 5 on the base 8.

[0048] Specifically, the third motor 16 on the base 13 is engaged with the rack 5 on the base 8 through a gear. When the third motor 16 rotates, the base 13 moves on the base 8 under the action of the third motor 16. When the lifting rod 14 moves up and down, the lifting table 15 located on the lifting rod 14 moves up and down, and the distance between the lifting table 15 and the pipe body 18 changes. When the lifting rod 14 extends, the lifting table 15 approaches the pipe body 18. When the lifting rod 14 contracts, the distance between the lifting table 15 and the pipe body 18 increases.

[0049] As shown in the Figure 1As shown in the figure, it further includes a first bearing platform 11 and a second bearing platform 7. The first bearing platform 11 is fixedly arranged on the base 8, the clamping chuck assembly 10 is rotatably arranged on the first bearing platform 11, the second bearing platform 7 is slidably arranged on the base 8, the top clamping block 6 is rotatably arranged on the second bearing platform 7, and a fourth motor is arranged on the second bearing platform 7 and is engaged with the rack 5 on the base 8.

[0050] Specifically, a gear is installed on the fourth motor, and the gear on the fourth motor is engaged with the rack 5 on the base 8. When the fourth motor works, the second bearing platform 7 moves on the base 8, and the distance between the first bearing platform 11 and the second bearing platform 7 changes accordingly, so that pipe bodies 18 of different lengths are clamped between the first bearing platform 11 and the second bearing platform 7.

[0051] As shown in the attached Figure 1 and 3 figure, a guiding slide rail 9 is arranged on the base 8, and the lifting seat is slidably engaged with the guiding slide rail 9.

[0052] Specifically, both the second bearing platform 7 and the bottom platform 13 of the lifting seat are slidably engaged with the guiding slide rail 9, and the second bearing platform 7 and the bottom platform 13 both move along the guiding slide rail 9 on the base 8.

[0053] As shown in the attached figure, a rack 5 is arranged on the guiding slide base, and a fifth motor 2 is arranged on the mechanical arm 3. The fifth motor 2 is engaged with the rack 5 on the guiding slide base.

[0054] A gear is installed on the shaft of the fifth motor 2, and the gear on the fifth motor 2 is engaged with the rack 5 on the guiding slide base. When the fifth motor 2 works, it drives the mechanical arm 3 to move on the guiding slide base.

[0055] As shown in the attached Figure 1 and 4 figure, the guiding slide base is in a parallel state with the base 8.

[0056] As shown in the attached Figure 1 and 4 figure, the top clamping block 6 is a conical top clamping block 6.

[0057] The conical top clamping block has a good top clamping effect on pipe bodies 18 with different pipe diameters. Embodiment
