Description

Technical Field

[0001] This utility model relates to the field of road marking equipment technology, specifically to a road marking hot melt spray gun. Background Technology

[0002] Road markings are signs on the road surface that use lines, arrows, words, vertical markings, raised pavement markers, and delineators to convey traffic information such as guidance, restrictions, and warnings to traffic participants. They are applied to the road surface using a hot melt spray gun by spraying high-temperature hot melt material.

[0003] Patent No. 201821880300.3 discloses a hot melt spray gun for road markings. This device uses high-pressure gas to drive hot melt paint to be sprayed out from the lower nozzle assembly, which speeds up the construction efficiency. Moreover, two spray guns can be connected in parallel to paint two markings at the same time, while the original machinery can only paint one marking at a time.

[0004] However, when using existing road marking hot melt spray guns, the nozzles on the hot melt spray guns spray out hot melt paint to achieve the purpose of road marking. However, after the hot melt spray gun is used, foreign objects will adhere to the nozzles of the hot melt spray gun, causing the nozzles to become clogged and affecting the service life of the hot melt spray gun. Therefore, a new type of road marking hot melt spray gun is needed. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a road marking hot melt spray gun.

[0006] The technical solution adopted by this utility model to solve its technical problem is a road marking hot melt spray gun, including a hot melt spray gun body and a nozzle. The hot melt spray gun body is provided with a protective component to protect the nozzle. The protective component includes a protective plate A, a protective plate B and a fixing sleeve. The fixing sleeve is slidably connected to the outside of the hot melt spray gun body. The protective plate A and the protective plate B are slidably connected to the inside of the fixing sleeve. The fixing sleeve is provided with a fixing component to fix the protective plate A and the protective plate B. Magnetic blocks are screwed to the outside of the protective plate A and the protective plate B. A magnetic ring connected to the magnetic blocks is screwed to the end of the hot melt spray gun body.

[0007] Specifically, when the hot melt spray gun body is no longer in use, the fixing sleeve outside the hot melt spray gun body is pushed to slide, and then the fixing component inside the fixing sleeve drives the protective component on the fixing sleeve to fix at the end of the hot melt spray gun body, thereby facilitating the protection of the nozzle on the hot melt spray gun body.

[0008] By adopting the above technical solution, the fixing component includes a fixing rod, spring A, support rod A, spring B and support rod B. Spring A is welded inside the fixing sleeve, and support rod A is inserted into the inner side of spring A. The end of support rod A is welded to the outside of the protective plate A.

[0009] Specifically, when the pressure on spring A is released, spring A causes support rod A to retract into the fixed sleeve, and then support rod A causes protective plate A to enter the fixed sleeve.

[0010] By adopting the above technical solution, a spring B is welded to the inner side of the fixed sleeve, and a support rod B is inserted into the inner side of the spring B, and a protective plate B is welded to the end of the support rod B.

[0011] Specifically, when the pressure on spring B is released, spring B causes support rod B to retract into the fixed sleeve, and then support rod B causes protective plate B to move, so that protective plate B enters the fixed sleeve.

[0012] By adopting the above technical solution, rubber pads are adhered to the surfaces of both protective plate A and protective plate B.

[0013] Specifically, when protective plate A and protective plate B come into contact, the rubber pads on protective plate A and protective plate B are squeezed by protective plate A and protective plate B. The rubber pads are elastic and fill the gap between protective plate A and protective plate B, thereby improving the sealing between protective plate A and protective plate B.

[0014] By adopting the above technical solution, both the protective plate A and the protective plate B are welded with fixing rods on the outside.

[0015] Specifically, when it is necessary to move protective plate A and protective plate B, the fixed rods outside protective plate A and protective plate B are pulled respectively. Then, the two sets of fixed rods move protective plate A and protective plate B respectively, thus facilitating the movement of protective plate A and protective plate B.

[0016] By adopting the above technical solution and connecting to an external power source, the electrical equipment can operate normally.

[0017] The beneficial effects of this utility model are:

[0018] (1) The road marking hot melt spray gun of this utility model, when the hot melt spray gun body is no longer in use, pushes the fixed sleeve outside the hot melt spray gun body to slide. The spring A and spring B inside the fixed sleeve are initially in a compressed state. As the fixed sleeve moves outside the hot melt spray gun body, the protective plate A and protective plate B inside the fixed sleeve are released from compression. Then, spring A drives the support rod A to retract into the fixed sleeve, so that the support rod A drives the protective plate A into the fixed sleeve. Spring B drives the support rod B to retract into the fixed sleeve, so that the support rod B drives the protective plate B into the fixed sleeve. So that the protective plate A and protective plate B move to the end of the hot melt spray gun body. Then, the arc-shaped magnetic block installed on the protective plate A and protective plate B is magnetically connected to the magnetic ring at the end of the hot melt spray gun body, so that the protective plate A and protective plate B are fixed at one end of the hot melt spray gun body, thereby facilitating the protection of the nozzle inside the hot melt spray gun body.

[0019] (2) When the hot melt spray gun for road markings described in this utility model is to be used on the hot melt spray gun body, the fixing rods outside the protective plate A and the protective plate B are pulled respectively. Then the magnetic blocks on the protective plate A and the protective plate B are separated from the magnetic ring at the end of the hot melt spray gun body. Then the protective plate A presses the spring A through the support rod A, and the protective plate B presses the spring B through the support rod B. Then the protective plate A and the protective plate B are moved out of the fixing sleeve. Then the fixing sleeve is pulled to slide outside the hot melt spray gun body, so that the fixing sleeve moves to the outside of the hot melt spray gun body. At the same time, the spring A drives the protective plate A to press the surface of the hot melt spray gun body through the support rod A, and the spring B drives the protective plate B to press the surface of the hot melt spray gun body through the support rod B, so as to facilitate fixing the fixing sleeve to the outside of the hot melt spray gun body.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] To protect the nozzle 9 on the body 1 of the hot melt spray gun, as one embodiment of this utility model, such as Figures 1 to 3As shown, the present invention discloses a road marking hot melt spray gun, comprising a hot melt spray gun body 1 and a nozzle 9. The hot melt spray gun body 1 is provided with a protective component 5 for protecting the nozzle 9. The protective component 5 includes a protective plate A3, a protective plate B4 and a fixing sleeve 2. The fixing sleeve 2 is slidably connected to the outside of the hot melt spray gun body 1. The protective plate A3 and the protective plate B4 for protecting the nozzle 9 are slidably connected to the inside of the fixing sleeve 2. The fixing component 12 for fixing the protective plate A3 and the protective plate B4 is provided inside the fixing sleeve 2. Magnetic blocks 7 are screwed to the outside of the protective plate A3 and the protective plate B4. A magnetic ring 8 connected to the magnetic block 7 is screwed to the end of the hot melt spray gun body 1.

[0027] When in use, when the hot melt spray gun body 1 is finished, push the fixing sleeve 2 outside the hot melt spray gun body 1 to slide, and then the fixing component 12 set inside the fixing sleeve 2 drives the protective component 5 on the fixing sleeve 2 to be fixed at the end of the hot melt spray gun body 1, so as to facilitate the protection of the nozzle 9 on the hot melt spray gun body 1.

[0028] In order to move the protective plate A3 into the fixing sleeve 2, for example, as follows: Figure 3 As shown, the present invention also includes the fixing component 12, which includes a fixing rod 15, a spring A11, a support rod A10, a spring B14, and a support rod B13. The fixing sleeve 2 has a spring A11 welded inside, and a support rod A10 is inserted into the inner side of the spring A11. The end of the support rod A10 is welded to the outside of the protective plate A3.

[0029] When in use, when the pressure on spring A11 is released, spring A11 drives support rod A10 to retract into fixed sleeve 2, and then support rod A10 drives protective plate A3 into fixed sleeve 2.

[0030] To allow the protective plate B4 to enter the fixing sleeve 2, for example, as follows: Figure 3 As shown, the present invention also includes a spring B14 welded to the inner side of the fixing sleeve 2, a support rod B13 inserted into the inner side of the spring B14, and a protective plate B4 welded to the end of the support rod B13.

[0031] When in use, when the pressure on spring B14 is released, spring B14 drives support rod B13 to retract into fixed sleeve 2, and then support rod B13 drives protective plate B4 to move, so that protective plate B4 enters fixed sleeve 2.

[0032] To improve the sealing between protective plate A3 and protective plate B4, for example, such as Figure 1 As shown, the present invention also includes rubber pads 6 adhered to the surfaces of both the protective plate A3 and the protective plate B4.

[0033] When in use, when protective plate A3 and protective plate B4 come into contact, the rubber pad 6 on protective plate A3 and protective plate B4 is squeezed by protective plate A3 and protective plate B4. The rubber pad 6 is elastic and fills the gap between protective plate A3 and protective plate B4, thereby improving the sealing between protective plate A3 and protective plate B4.

[0034] To move protective plates A3 and B4, for example, as follows: Figure 3 As shown, the present invention also includes fixing rods 15 welded to the outside of both the protective plate A3 and the protective plate B4.

[0035] When in use, to move the protective plates A3 and B4, pull the fixing rods 15 on the outside of the protective plates A3 and B4 respectively. Then, the two sets of fixing rods 15 will move the protective plates A3 and B4 respectively, thus facilitating the movement of the protective plates A3 and B4.

[0036] In use, when the hot melt spray gun body 1 is finished, the fixed sleeve 2 outside the hot melt spray gun body 1 is pushed to slide. Springs A11 and B14 inside the fixed sleeve 2 are initially compressed. As the fixed sleeve 2 moves outside the hot melt spray gun body 1, the protective plates A3 and B4 inside the fixed sleeve 2 are released from compression. Then, spring A11 drives the support rod A10 to retract into the fixed sleeve 2, causing the support rod A10 to pull the protective plate A3 into the fixed sleeve 2. Spring B14 drives the support rod B13 to retract into the fixed sleeve 2, causing the support rod B13 to pull the protective plate B4 into the fixed sleeve 2. This moves the protective plates A3 and B4 to the end of the hot melt spray gun body 1. Then, the arc-shaped magnetic blocks 7 installed on the protective plates A3 and B4 are magnetically connected to the magnetic ring 8 at the end of the hot melt spray gun body 1. The magnetic blocks 7 and the magnetic ring 8 have opposite magnetic properties, thus fixing the protective plates A3 and B4 to the hot melt spray gun body 1. At the end of the meltblown gun body 1, the nozzle 9 inside the meltblown gun body 1 is protected. When the meltblown gun body 1 is to be used, the fixing rods 15 outside the protective plate A3 and the protective plate B4 are pulled respectively. Then the magnetic blocks 7 on the protective plate A3 and the protective plate B4 are separated from the magnetic ring 8 at the end of the meltblown gun body 1. Then the protective plate A3 presses the spring A11 through the support rod A10, and the protective plate B4 presses the spring B14 through the support rod B13. Then the protective plate A3 and the protective plate B4 are moved out of the fixing sleeve 2. Then the fixing sleeve 2 is pulled to slide outside the meltblown gun body 1, so that the fixing sleeve 2 moves to the outside of the meltblown gun body 1. At the same time, the spring A11 drives the protective plate A3 to press the surface of the meltblown gun body 1 through the support rod A10, and the spring B14 drives the protective plate B4 to press the surface of the meltblown gun body 1 through the support rod B13, so as to facilitate fixing the fixing sleeve 2 to the outside of the meltblown gun body 1.
