Description

Glue gun

This application requires the priority of a Chinese patent application with an application date of November 08, 2018 and application number 201821838876.3. The entire contents of this application are incorporated by reference in this application.

Technical field

The present disclosure relates to the technical field of hardware appliances, for example, to a glue gun.

Background technique

In the related art, the glue gun usually includes a hose bracket and a support frame that are fixed together. The hose bracket and the support frame are slidingly connected with a push rod, the push rod is connected with a push block, and the push block is connected with a connecting rod group and a connecting rod. The group is connected to the trigger. When the trigger is pressed, the trigger drives the connecting rod to move, and the connecting rod pushes the push block, which in turn pushes the push rod to move forward. The trigger is directly pivotally connected to a link in the connecting rod group to use the trigger Press to drive the linkage group.

The above glue gun uses the principle of lever balance to extrude the colloid. The theoretical formula is: power × power arm = resistance × resistance arm (ie, F1 × L1 = F2 × L2). Since power F1 is the triggering force of the finger, the The force is small, the power arm L1 is limited by the gun body structure and the size of the palm, and it cannot be very long. The F2 and the resistance arm L2 of the extruded colloid are fixed, so long-term operation, finger fatigue, effort, work Poor efficiency.

In addition, the above-mentioned complicated link mechanism is not only difficult to manufacture and assemble, but also, after a long period of use, the pivotal joint between the links will be difficult to rotate or get stuck due to rust, resulting in inconvenience in use.

Summary of the invention

The present disclosure proposes a glue gun with screw drive power. The glue gun adopts a screw with a small torque to rotate to generate a large axial thrust, so as to easily extrude the gel.

A glue gun includes a support frame and a transmission mechanism, wherein the support frame has opposite first and second ends; the transmission mechanism is connected to the second end, and the transmission mechanism includes: a screw The screw is connected to the second end; a push rod, the push rod is configured to extend into the support frame through the second end, and can move relative to the second end, and the push rod extends The end of the support frame is connected with the screw rod; and a handle, the handle is threadedly connected with the end of the screw rod extending out of the support frame, the handle is configured to drive the screw rod to rotate to push the The push rod moves relative to the second end.

BRIEF DESCRIPTION

2 is a plan view of a glue gun provided by an embodiment.

In the picture: 10-support frame, 11-first end, 12-second end, 13-support plate, 21-screw, 22-push rod, 23-handle, 24-push plate, 26-piston, 27-recess mouth.

detailed description

As shown in FIGS. 1 and 2, the glue gun of this embodiment includes a support frame 10 and a transmission mechanism. Wherein, the supporting frame 10 is configured to accommodate the hose, and the supporting frame 10 has a first end 11 and a second end 12 opposite to each other. The first end 11 is provided with a recess 27 or a through hole (not shown) for the nozzle of the hose ); The transmission mechanism is connected to the second end 12, the transmission mechanism includes a screw 21, a push rod 22 and a handle 23, the screw 21 is connected to the second end 12; the push rod 22 extends into the support frame 10 through the second end 12 and can It moves relative to the second end 12, and the end of the push rod 22 extending out of the support frame 10 is connected to the screw 21; the handle 23 is screwed to the end of the screw 21 extending out of the support frame 10.

When gluing, put the hose into the support frame 10, the first end of the hose is pressed against the first end 11, the end of the push rod 22 is pressed against the second end of the hose, rotate the handle 23, the push rod 22 Pushing force is applied, so that the push rod 22 squeezes the rubber tube, so that the rubber tube is discharged. It can be seen that the glue gun of this embodiment only needs to rotate the handle 23, so that the push rod 22 can squeeze the hose. The operation is labor-saving, the overall structure is simple, the cost is low, and the hose is easy to install.

In one embodiment, the screw 21 of the glue gun is movably sleeved with a push plate 24, a first end of the push plate 24 is connected with a push rod 22, the push rod 22 is located on the first side of the screw 21, and the push plate 24 A push rod 22 is also connected to the two ends. The push rod 22 is located on the second side of the screw 21, and the two push rods 22 are arranged in parallel. In this way, by using the two push rods 22, the two hoses can be squeezed at the same time, which greatly improves the efficiency and efficiency of the glue application.

In addition, a piston 26 is provided on the end of the two push rods 22 extending into the support frame 10, and the piston 26 is used to squeeze the rubber tube, and the contact is good.

The support frame 10 in this embodiment is used to accommodate hoses. In order to stably support the hoses, the side walls of the support frame 10 are provided with support plates 13 extending horizontally into the support frame 10. The edges of the support plates 13 are The support frame 10 has a gap between the side walls facing the support plate 13, and the gap is smaller than the outer diameter of the hose to be installed. The glue gun provided in this embodiment saves the cost of the support frame 10 and also prevents the glue tube from falling. In an embodiment, a supporting plate 13 extending horizontally into the supporting frame 10 may be provided on two opposite side wall edges of the supporting frame 10, and there is a gap between the two supporting plates 13, the gap is smaller than that to be installed The outer diameter of the hose. A supporting plate 13 may also be connected between two opposite side wall edges of the supporting frame 10. From the perspective of cost savings, the first two methods are more cost-effective.

Compared with the glue gun in the related art, the glue gun of this embodiment has a simple and reliable structure, is not prone to failure, is easy to manufacture, convenient to operate, and relatively labor-saving.
