Description

Technical Field

[0001] The utility model relates to the technical field of spraying room installation, in particular to a lifting and adjusting device for supporting upright poles of a spraying system. Background Art

[0002] As is known, the spray booth has a large number of conveying tracks and suspended parts, so a lot of support rods are needed for supporting frame installation. However, during on-site construction and assembly, due to assembly deviation, it is often necessary to adjust the height of the support rod uprights to meet the precise installation requirements, otherwise it will affect the normal spraying operation of the spray booth. There are two traditional commonly used height adjustment methods: one is to adjust by screwing the support bolts, which has the advantage of arbitrarily adjusting the height within a certain range, and the disadvantage is that the support bolts are usually contact supports, which limits the bottom surface connection method of the support uprights and is not stable enough; the other is to set the support uprights as inner and outer outer sleeves, and set a plurality of connecting holes at intervals along the axial direction of the inner and outer outer sleeve walls, and by adjusting the height of the outer sleeve, bolts are inserted into the corresponding connecting holes of the inner and outer sleeves for connection, which has the advantage of having little effect on the supporting structure and supporting stability of the entire support upright, and the disadvantage is that the height can only be adjusted according to the spacing of the connecting holes, that is, the height adjustment is intermittent, not continuous; therefore, these two traditional lifting and adjusting methods cannot take into account the requirements of support stability and adjustment continuity. Utility Model Content

[0003] In order to overcome the deficiencies in the background technology and solve the existing technical problems, the utility model discloses a lifting and adjusting device for a support pole of a spraying system, which can take into account the requirements of support stability and adjustment continuity.

[0004] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0005] A spray system support pole lifting and adjustment device comprises an inner rod and a sleeve adapted to be mounted outside the inner rod and capable of sliding along the axial direction of the inner rod; the inner rod has at least one flat side wall, the flat side wall is provided with an inclined groove, the sleeve is provided with a long inclined hole on the tube wall corresponding to the flat side wall, the inclined groove and the long inclined hole are correspondingly cross-arranged, and both have an angle with the axial direction of the inner rod; a nut with an axis perpendicular to the flat side wall is clamped in the inclined groove, and the nut can slide along the inclined groove, and a screw capable of being screwed into the nut is correspondingly passed through the long inclined hole.

[0006] Furthermore, the inner rod is configured as a hollow rod, and the inclined slide groove is configured as an inclined bar hole.

[0007] Furthermore, the nut is configured as a clip nut, and two clip plates are symmetrically provided on both sides of the clip nut, and the clip plates are concave to form a clip groove that can correspondingly clip the corresponding hole edge of the inclined strip hole.

[0008] Furthermore, the clamping plate is configured as an elastic member, the lower part of the clamping plate is fixed to the outer side wall of the nut body of the clip nut, and the clamping groove is arranged at the upper part of the clamping plate; the hole wall at one end of the inclined bar hole is widened to form two symmetrical steps, the step surface of the step is configured as an inclined surface sloping downward toward the other end of the inclined bar hole, and the distance between the two steps is narrowed to be smaller than the width of the other end of the inclined bar hole.

[0009] Furthermore, the flat side wall surface is provided with two inclined slide grooves spaced apart and arranged side by side.

[0010] Furthermore, the inner rod is provided with at least two corresponding parallel flat side walls, and the two inclined slide grooves of the two flat side walls are correspondingly cross-arranged.

[0011] Furthermore, the angle between the inclined slide groove and the long inclined hole and the axial direction of the inner rod is 20 to 45 degrees.

[0014] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0015] The lifting and lowering adjustment device of the support pole of the spraying system disclosed by the utility model adopts a radially penetrated screw connection method to squeeze and fix the inner rod and the sleeve of the adapter assembly, thereby ensuring the structural strength and stability of the entire structure, and at the same time utilizes the inclined slide groove of the inner rod and the long inclined hole of the sleeve to be cross-arranged, so that within a certain range, no matter how the height of the sleeve is adjusted, there will always be an overlapping space portion between the long inclined hole and the inclined slide groove for the screw to pass through the threaded nut, thereby meeting the demand for continuous height adjustment, and once the connection is screwed and fixed, the axial support load of the sleeve wants to force the sleeve to move downward, and it is necessary to overcome the friction between the screw head and the sleeve when the screw is screwed and squeezed, and the friction between the nut and the inclined slide groove. The larger the inclination angle, the greater the screw tightening force, the greater the friction and the inclined support component force, thereby being sufficient to meet the support demand of the sleeve.

[0021] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" and the like indicating directions or positional relationships, they are only corresponding to the drawings of the present invention, for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction: Embodiment 1:

[0022] Combined with Figure 1 The spray system support pole lifting and adjusting device comprises an inner pole 1, and a sleeve 2 adapted to be mounted outside the inner pole 1 and capable of sliding axially along the inner pole 1. The sleeve 2 has a similar appearance structure to the inner pole 1 and is sleeved on the upper part of the inner pole 1, thereby having sufficient radial limit. A base plate 5 is fixed to the bottom surface of the inner pole 1, and is firmly connected to the foundation through the base plate 5 to increase the support area.

[0023] The inner rod 1 has at least one flat side wall, and the flat side wall is provided with an inclined groove. The flat side wall ensures that the length of the inclined groove on the surface is smooth, and the inclined groove has a sufficient groove depth to ensure space for the screw to be screwed in; according to needs, two inclined grooves are arranged side by side on the flat side wall at intervals, and the number of screws 3 is increased by setting multiple inclined grooves to ensure sufficient connection strength; the sleeve 2 is provided with a long inclined hole 201 on the tube wall corresponding to the flat side wall, and the inclined groove and the long inclined hole 201 are arranged in parallel and crosswise, and both have an angle with the axial direction of the inner rod 1; according to needs, the angle between the inclined groove and the long inclined hole 201 and the axial direction of the inner rod 1 is 20 to 45 degrees, generally set to 25 degrees; a nut with an axis perpendicular to the flat side wall is clamped in the inclined groove, and the nut can slide along the inclined groove, and specifically, a slideway can be set on the inner groove wall of the inclined groove so that the corresponding side of the nut is just stuck in the slideway, and the long inclined hole 201 is correspondingly penetrated with a screw 3 that can be adapted to screw into the nut.

[0024] According to needs, the inner rod 1 is set as a triangular rod, a quadrangular rod or a pentagonal rod, then the inner rod 1 will have three, four or five flat side walls, which are used to arrange the inclined slide grooves for connection, thereby increasing the connection strength; in addition, the inner rod 1 is provided with at least two corresponding parallel flat side walls, and the two inclined slide grooves of the two flat side walls are correspondingly cross-arranged, that is, the two inclined slide grooves of the two flat side walls are inclined in opposite directions, so that the directions of the inclined supporting component forces inclined upward do not overlap, and the axial support load of the casing has a greater supporting force.

[0025] When implementing the spray system support pole lifting and adjusting device of the utility model, when it is necessary to adjust the lifting height of the sleeve 2, it is only necessary to loosen the screw 3, then lift or lower the sleeve 2, and at the same time move the screw 3 with the nut threaded together, slide them into place along the inclined slide groove and the long inclined hole 201 respectively, and then tighten the screw 3 to complete the adjustment and fixation. Embodiment 2:

[0026] The difference from the first embodiment is that, as shown in the attached Figure 2-4 As shown, the inner rod 1 is designed to be a hollow rod, the inclined slide groove is designed to be an inclined strip hole 101, and the nut is designed to be a clip nut 4. The clip nut 4 is a part available on the market, and its structure is similar to Figure 4 As shown, two clamping plates 401 are symmetrically arranged on both sides of the clip nut 4, and the clamping plates 401 are concave to form a clamping groove that can clamp the corresponding hole edge of the inclined strip hole 101, and the clamping plate 401 is set as an elastic member. The lower part of the clamping plate 401 is fixed to the outer side wall of the nut body of the clip nut 4, and the clamping groove is set at the upper part of the clamping plate 401;

[0027] In order to facilitate the installation of the clip nut 4, the hole wall at one end of the inclined bar hole 101 is widened to form two symmetrical steps 102. The widened end of the inclined bar hole 101 is used to place the corresponding clip nut 4, so that the card slot of the card plate 401 can correspond to the upper hole edge. The step surface of the step 102 is set to be an inclined surface sloping downward toward the other end of the inclined bar hole 101, and the distance between the two steps 102 is narrowed to be smaller than the width of the other end of the inclined bar hole 101. The clip nut 4 can slide smoothly into the inclined bar hole 101 under the guidance of the inclined surface of the step 102, and tightly fit the hole edge that has not been widened. The narrowed part of the two steps 102 can limit the clip nut 4 to prevent the clip nut 4 from sliding out.
