Technical Field

[0001] The utility model relates to the technical field of pipeline butt installation, in particular to a heating and ventilation pipeline installation butt installation device. Background Art

[0002] Heating and ventilation ducts are metal or composite ducts used in ventilation and air-conditioning projects in industrial and civil buildings. They are a kind of municipal infrastructure designed to allow air circulation and reduce the concentration of harmful gases.

[0003] The existing docking device for docking heating and ventilation ducts has a complex installation structure. For example, a heating and ventilation duct installation docking device proposed in the document with publication number CN202321683775.4 improves the tightness of the connection between the two ventilation ducts by cooperating with structures such as a first fixing ring, a clamping mechanism, a fixing block, a limiting structure, and a second fixing ring. Such structural coordination leads to slow docking assembly operation speed, and it is necessary to fix the positions of the pipes at both ends before docking, which is time-consuming and laborious. Therefore, a structure that can be quickly docked is needed. In view of this, we propose a heating and ventilation duct installation docking device. Utility Model Content

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] Embodiment: A heating and ventilation duct installation docking device, see Figures 1 to 6 , including two limit kits 1, both ends of the two limit kits 1 are fixed with matching connecting plates 3, and a limit clamp 4 is installed between the two connecting plates 3 on one side. The connecting plates 3 on both sides are fitted and then the limit clamp 4 is inserted into the outer side of the connecting plates 3 on both sides to fix the combined position of the two limit kits 1, so that the two ventilation ducts can be clamped and limited;

[0025] Two groups of card slots 101 and limiting slots 102 are provided on the side surfaces of the two limiting kits 1 on the side facing each other, and each group of card slots 101 is integrally connected with the limiting slots 102, and a connector 2 is in contact with and connected between the upper and lower card slots 101, and a groove 201 corresponding to the limiting slot 102 is provided on the side wall of the connecting member 2, and a ventilation duct is fixed between the inner walls of the connecting member 2; by arranging the connecting member 2 on the ventilation duct, it is convenient to card into the inside of the card slot 101, so that the effect of positioning and installation can be achieved, and there is no problem of offset, and the cooperation between the limiting slot 102 and the groove 201 can enhance the tightness of the combination and improve the connection sealing effect, thereby facilitating and quickly fixing the position of the two ventilation ducts.

[0026] Specifically, positioning grooves 301 are provided on the sides of the two connecting plates 3 on one side that are away from each other, and resistance grooves 302 are connected to the groove edges of the positioning grooves 301. Positioning protrusions 402 combined with the positioning grooves 301 are fixedly provided on the upper and lower inner walls of the limiting clamp 4, and resistance sheets 403 combined with the resistance grooves 302 are fixedly provided on the sides of the positioning protrusions 402. The positioning protrusions 402 can be stuck into the positioning grooves 301 by combining the limiting clamp 4 with the connecting plate 3, so that the limiting clamp can be prevented from moving 4 under the action of translation, thereby achieving the effect of limiting connection. The combination of the resistance sheet 403 and the resistance groove 302 can enhance the effect of connection limitation, and the size of the clamp can be adjusted by the elastic force of the limiting clamp 4 itself, so as to facilitate the removal of the limiting clamp 4.

[0027] Furthermore, a positioning block 303 is fixed on the upper side surface of the lower connecting plate 3, and a positioning hole 304 combined with the positioning block 303 is opened on the plate wall of the upper connecting plate 3; the positioning block 303 is combined with the positioning hole 304 to quickly fix the combined position of the two limit kits 1, eliminating the alignment operation step.

[0028] Furthermore, an inclined portion 401 is provided between the side surfaces and the front end sides of the limiting clamp 4 which are in contact with the connecting plates 3 on both sides; the setting of the inclined portion 401 can form an angle with the connecting plates 3, so that the side plate of the limiting clamp 4 can be tilted up through the position of the inclined portion 401, so that the positioning protrusion 402 is separated from the positioning groove 301, which is convenient for the separation operation.

[0029] It is worth noting that arc grooves 404 are provided at two angles between the inner walls of the limiting clamp 4, and the two arc grooves 404 have the same shape; the setting of the arc grooves 404 can increase the folding angle of the two side plates of the limiting clamp 4 and reduce the limiting force.

[0030] It is worth noting that convex strips 405 are provided on the two adjacent side surfaces of the limit clamp 4, and a strip groove 305 combined with the convex strip 405 is opened on the plate wall of the connecting plate 3; the position where the limit clamp 4 is combined with the connecting plate 3 can be located through the combination of the convex strip 405 and the strip groove 305, so that the positioning protrusion 402 can be quickly aligned with the positioning groove 301 without the need for adjustment operation.

[0031] It is worth mentioning that a glue injection groove 406 is provided on the side where the limiting clamp 4 and the connecting plate 3 are in contact. The setting of the glue injection groove 406 can form a glue injection gap to facilitate glue penetration and improve the bonding strength.

[0032] Working principle: First, clamp the limiting kit 1 on one side between the two ventilation ducts, so that the connector 2 on the ventilation duct is combined with the card slot 101 on the limiting kit 1, so as to fix the installation position of the limiting kit 1, and then place the other limiting kit 1 above the ventilation duct, so that the positions of the two limiting kits 1 are aligned, and the positioning block 303 is combined with the positioning hole 304 to limit the position of the connecting plates 3 on both sides, so that the upper part of the connecting piece 2 can be inserted into the upper card slot 101, so that the pipe mouth of the ventilation duct can be wrapped inside, and then the limiting clamp 4 is placed on a The outside of the two side connecting plates 3 are connected by extrusion, so that the limit clamp 4 can clamp and limit the connecting plates 3 on both sides. When the positioning protrusion 402 on the inner wall of the limit clamp 4 moves to the position of the positioning groove 301 on the connecting plate 3, it can automatically get stuck. At the same time, the resistance pieces 403 on both sides can also be combined with the resistance groove 302 to fix the installation position of the limit clamp 4. In this way, the assembly operation of the two limit kits 1 can be completed, thereby fixing the docking position of the two ventilation ducts. Through such structural coordination, the operation steps can be effectively reduced, the time of docking operation can be saved, and it is easy to use.
