Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] Example 1 like Figures 1 to 4 As shown, a spraying connection device is used to quickly connect the end of an external pipe through which protective paint is sprayed to a spray gun for spraying protective paint onto the housing of a filter press. The connection device includes a first connector 1 and a second connector 2, which are detachably connected. The end of the first connector 1 away from the second connector 2 is used to connect to the end of the external pipe through which the paint is sprayed. A movable limiting sleeve 11 is movably and hollowly disposed within the cavity of the first connector 1. A limiting structure for limiting the connection of the second connector 2 is disposed within the cavity of the movable limiting sleeve 11 near the second connector 2. An elastic movable protective member is disposed within the hollow cavity of the second connector 2 near the first connector 1, and the elastic movable protective member is elastically connected to the hollow cavity of the second connector 2. The end of the second connector 2 away from the first connector 1 is used to connect to the inlet end of the spray gun.

[0014] In this embodiment, one end of the first connector 1 of the connecting device is used to connect to the end of the external pipe through which the paint is sprayed, and one end of the second connector 2 is used to connect to the inlet end of the spray gun. When it is necessary to connect the spray gun to the external pipe through which the paint is sprayed, the movable limiting sleeve 11 of the first connector 1 is aligned with the through cavity of the second connector 2 and placed in the second connector 2. During the process of placing the movable limiting sleeve 11 in the second connector 2, as the depth of the movable limiting sleeve 11 entering the second connector 2 increases, the movable limiting sleeve... 11. Push the elastic movable protective member "moving" in the second connector 2 and for protecting the second connector 2; when the movable limiting sleeve 11 enters the second connector 2 to a certain depth, then rotate the end "nut" of the external pipe connected to the first connector 1. One end of the nut has a certain through-hole boss, and the other end of the boss is placed at one end of the first connector 1; rotating the end "nut" causes the boss to move the elastic movable protective member, and the elastic movable protective member limits the movable limiting sleeve 11 in the second connector 2, thereby realizing the connection between the first connector 1 and the second connector 2.

[0015] Example 2 Based on Embodiment 1, the outer wall of the movable limiting sleeve 11 near the second connector 2 is bolted to the inner wall of the first connector 1, and the outer wall of the movable limiting sleeve 11 away from the second connector is connected to an end cap 12, which is movably disposed in the through cavity of the first connector 1; an outer deformation spring 13 is sleeved on the movable limiting sleeve 11, one end of which is used to contact the end cap 12, and the other end of which is used to connect to the inner wall of the through cavity of the first connector 1.

[0016] In this embodiment, the length of the movable limiting sleeve 11 and the second connector 2 can be adjusted by rotating the movable limiting sleeve 11 as needed. When the movable limiting sleeve 11 rotates in the cavity of the first connector 1, the outer deformation spring 13 provides a certain elastic protection.

[0017] Example 3 Furthermore, the limiting structure includes a through-hole movable limiting shaft 3; the movable limiting shaft 3 is movably inserted into the movable limiting sleeve 11, and a movable retaining ring 31 is connected to the end of the movable limiting shaft 3 away from the second connector 2; the movable limiting sleeve 11 has several limiting movable holes at the end near the second connector 2, and a movable limiting stop ball 32 is elastically and movably disposed in the limiting movable holes by a spring; the movable limiting shaft 3 at the end near the second connector 2 is tapered, and the tapered end of the movable limiting shaft 3 is used to contact the movable limiting stop ball 32, pushing the movable limiting stop ball 32 to move outward of the limiting movable hole, and to abut against the inner wall of the second connector 2. An inner deformation spring 33 is elastically sleeved on the movable limiting shaft 3, one end of the inner deformation spring 33 is used to connect to the movable retaining ring 31, and the other end of the inner deformation spring 33 is used to connect to the inner wall of the movable limiting sleeve 11.

[0018] In this embodiment, by rotating the end "nut" of the external pipe connected to the first connector 1, one end of the nut has a centrally located boss, and the other end of the boss is positioned at one end of the first connector 1; rotating the end "nut" moves relative to the first connector 1 (equivalent to a threaded connection), and the boss moves towards the movable retaining ring 31 inside the first connector 1; after the boss contacts the movable retaining ring 31, as the boss continues to move deeper, it pushes the movable retaining ring 31 along the inner wall of the movable limiting sleeve 11, and... Under the elastic protection of the inner deformation spring 33, the tapered end of the movable limiting shaft 3 is driven to contact the end face of the movable limiting stop ball 32. As the movable limiting shaft 3 continues to move, the tapered end of the movable limiting shaft 3 with the larger cross-section pushes the movable limiting stop ball 32 toward the outside of the limiting movable hole, so as to abut against the inner wall of the second connector 2, and limit the movable limiting sleeve 11 to be locked in the inner wall of the second connector 2 by the movable limiting stop ball 32, so as to realize the quick connection of the first connector 1 and the second connector 2.

[0019] Example 3 Furthermore, the elastic movable protective component disposed in the second connector 2 includes a movable guide cylinder 21 hollowly disposed therethrough, the movable guide cylinder 21 being installed and connected in the hollow cavity of the second connector 21; a connecting plate is connected to the end of the movable guide cylinder 21 away from the movable limiting sleeve 11; a movable plug 22 is disposed at the end of the movable guide cylinder 21 near the movable limiting sleeve 11, the movable plug 22 being elastically movably disposed at the end of the second connector 2 near the movable limiting sleeve 11. A movable guide shaft 23 is connected to the end of the movable plug 22 near the connecting plate, the other end of the movable guide shaft 23 being movably inserted into the movable guide cylinder 21; a movable spring 24 is elastically sleeved on the movable guide shaft 23, one end of the movable spring 24 being connected to the movable guide shaft 23, and the other end of the movable spring 24 elastically inserting into the movable guide cylinder 21 and being connected to the connecting plate.

[0020] In this embodiment, the movable plug 22 is movably disposed in the cavity of the second connector 21 and is slidably matched with the inner wall of the cavity of the second connector 21 near the movable limiting sleeve 11. When the movable limiting sleeve 11 has not yet entered the cavity of the second connector 21, the movable plug 22 is disposed at the end of the second connector 21 near the movable limiting sleeve 11 to "block" the second connector 21 and prevent external slag, particles, etc. from entering the second connector 21 and blocking it. During connection, as the movable limiting sleeve 11 enters the second connector 21 to a greater depth, the movable limiting sleeve 11 pushes the movable plug 22 towards the "bottom" of the movable guide cylinder 21 under the elastic protection and guidance of the movable spring 24, thereby allowing the movable limiting sleeve 11 to enter the second connector 21. After entering to a certain depth, the movable limiting sleeve 11 and the second connector 21 are "limited connected" by the "limiting structure of control embodiment 2", ultimately achieving the purpose of connecting the first connector 1 and the second connector 2.
