Description

Technical Field

[0001] This utility model relates to a support structure for a hot melt machine, and more particularly to an integrated automatic foot support structure for a hot melt machine, belonging to the field of hot melt machine technology. Background Technology

[0002] As is well known, a hot melt welder is a welding tool used to heat and melt thermoplastic pipes and molds, and then perform hot melt welding. The connection of plastic pipes is achieved through a hot melt welder. However, the support structure of a conventional hot melt welder is relatively simple and unstable, for example:

[0003] The inventions with announcement number CN 213108283 U, entitled "A Thermal Power Dual-Use Hot Melting Device", and with announcement number CN205736001 U, entitled "Anti-scalding Pipe Fitting Hot Melting Device", both have a simple support structure. The installation and storage process is cumbersome and unstable. They are prone to tipping over during operation, causing the high-temperature heating head to come into contact with the ground. If it comes into contact with flammable materials, it can easily cause a fire, and if it comes into contact with people, it can easily cause burns, posing a great safety hazard. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing hot melt machine support structures, such as instability, easy tipping, and the risk of fire or burns. This invention provides an integrated automatic foot support structure for hot melt machines that automatically opens, provides stable support, prevents tipping, and avoids fire or burn accidents.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an integrated automatic foot support structure for a hot melt machine, including a main body housing, a handle, and a heating plate, wherein the handle is located at the rear of the main body housing; a heating plate insertion seat is provided at the front of the main body housing, wherein the heating plate is fixedly connected to the main body housing through the heating plate insertion seat;

[0006] It also includes an integrated automatic foot support structure, which includes a support housing, a support switch, a pull rod, a compression spring, support feet, and a locking plate. The support feet include a left support foot and a right support foot, and the front ends of the left support foot and the right support foot are bent downwards. The support housing is located below the main body housing, and the upper rear end face of the support housing is fixedly connected to the lower end face of the main body housing.

[0007] The bracket housing has an elbow at its rear end, and a switch through hole is provided at the top center of the elbow. The bracket switch is inserted through the switch through hole. The bottom surface of the bracket housing has a downward groove, and a pull rod is provided in the groove. The rear end of the pull rod is fixedly connected to the bracket switch, and a compression spring is sleeved on the pull rod. Moving the bracket switch can cause the pull rod to move back and forth in the groove.

[0008] The left and right support legs are respectively located on the left and right sides of the bracket housing; a left pin and a right pin are respectively provided on both sides of the elbow. The rear end of the left support leg is rotatably connected to the left side of the elbow through the left pin, and the rear end of the right support leg is rotatably connected to the right side of the elbow through the right pin.

[0009] The locking plate is horizontally arranged at the rear end of the pull rod, and the middle part of the locking plate is fixedly connected to the front end of the pull rod with two rivets; there is a sliding slot on each side of the groove in the middle of the bracket housing, and a locking head is provided on the front side of each of the left and right ends of the locking plate; the locking head at the left end of the locking plate is engaged with the sliding slot on the left side, and the left end of the locking head is engaged with the inner side of the bend of the left support leg; the locking head at the right end of the locking plate is engaged with the sliding slot on the right side, and the right end of the locking head is engaged with the inner side of the bend of the right support leg.

[0010] A left torsion spring is provided between the left support leg and the left side of the bracket housing. One end of the left torsion spring is fixedly connected to the left side of the bracket housing, and the other end of the left torsion spring is fixedly connected to the middle of the rear end of the left support leg. A right torsion spring is provided between the right support leg and the right side of the bracket housing. One end of the right torsion spring is fixedly connected to the right side of the bracket housing, and the other end of the right torsion spring is fixedly connected to the middle of the rear end of the right support leg.

[0011] When the external bracket switch is activated, the lever is pulled, and the locking plate is moved backward, the left and right ends of the locking head disengage from the inner sides of the left and right support legs, respectively. At this time, under the restoring force of the torsion spring, the left and right support legs are extended 90° to the left and right, respectively, so that the left and right support legs are in a straight line.

[0012] A temperature adjustment knob is located on the right side of the main unit housing, and a heating switch is located on the top of the main unit housing.

[0013] The heating plate is equipped with a die for heating thermoplastic pipes, through which the pipes are heated and then welded.

[0014] The length of the sliding slot should be greater than the width of the locking piece plus the protrusion, so that the left and right ends of the locking piece can be inserted into the sliding slot and move back and forth within the sliding slot.

[0015] Usage process:

[0016] (1) Initial state: The bracket switch is closed inward, the compression spring is in the compressed state, the torsion spring is in the tightened state, the left and right support legs are retracted, the locking plate is in the locked position, and the clasp is locked on the inner side of the bend of the left and right support legs;

[0017] (2) During use, when it is to be placed on a flat surface, turn on the external switch, the lever moves to the left, the spring opens, the locking plate moves backward in the sliding slot, and the locking plate is pulled away from the locking position; the torsion spring returns to the relaxed state, and under the action of the torsion spring's restoring force, the locking plate disengages from the sliding slot, and the left and right support feet rotate around the left and right pins respectively and spring open to both sides, thus realizing the function of the hot melt support bracket;

[0018] (3) When the use is over, manually tighten the left and right support legs inward, the pressure spring will be tightened again, the locking plate will be locked in the locking position, and the left and right support legs will be retracted.

[0019] Compared with the prior art, the beneficial effects of this utility model are: it designs an integrated automatic foot support structure for the hot melter, which allows the hot melter to automatically open the support structure with one button during operation, ensuring stable placement and preventing tipping over, thus avoiding fire or burn accidents and eliminating safety hazards during the welding process; moreover, the structure is simple, easy to store, and convenient to carry and operate.
