Description
本申请要求申请日为2018年11月08日、申请号201821838876.3为的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。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.
本公开涉及五金用具技术领域,例如涉及一种胶枪。The present disclosure relates to the technical field of hardware appliances, for example, to a glue gun.
相关技术中,胶枪通常包括固接在一起的胶管托架和支撑架,胶管托架和支撑架上滑动连接有推杆,推杆连接有推块,推块连接有连杆组,连杆组与扳机连接,当按压扳机,扳机带动连杆动作,连杆推动推块,进而推块带动推杆往前移动,其中,扳机直接与连杆组中的一连杆枢接,以利用扳机的按压来带动连杆组动作。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.
上述胶枪是采用杠杆平衡的原理挤出胶体,其理论公式为:动力×动力臂=阻力×阻力臂(即,F1×L1=F2×L2),由于动力F1就是手指的扳扣力,该力较小,动力臂L1受枪体结构和手掌大小的限制,不可能很长,而挤出胶体的F2及阻力臂L2又是固定不变的,这样长时间操作,手指疲劳,吃力,工作效率差。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.
此外,上述的复杂的连杆机构不但制造与组装较为困难,而且,长时间使用后,连杆之间的枢接处会因生锈导致不易转动或卡住的情况,造成使用不便。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.

如图1和图2所示,本实施例的胶枪包括支撑框架10和传动机构。其中,支撑框架10设置为容纳胶管,该支撑框架10具有相对的第一端11和第二端12,第一端11设有供胶管的喷嘴伸出的凹口27或通孔(未图示);传动机构与第二端12连接,传动机构包括螺杆21、推杆22和手柄23,螺杆21与第二端12连接;推杆22穿过第二端12伸入支撑框架10内并能够相对第二端12移动,且推杆22伸出支撑框架10的端部与螺杆21连接;手柄23与螺杆21伸出支撑框架10的端部螺纹连接。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.
打胶时,将胶管放入支撑框架10内,胶管的第一端抵压在第一端11上,推杆22的端部抵压在胶管的第二端上,旋转手柄23,对推杆22施加推力,从而使推杆22挤压胶管,使胶管出胶。可见,本实施例的胶枪只需旋转手柄23,即可使推杆22挤压胶管,操作省力,整体结构简单,成本低,且胶管安装方便。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.
一实施方式中,该胶枪的螺杆21活动套接有推板24,推板24的第一端连接有一根推杆22,该推杆22位于螺杆21的第一侧,推板24的第二端也连接有一根推杆22,该推杆22位于螺杆21的第二侧,两根推杆22平行设置。如此,利用两根推杆22,可同时对两个胶管进行挤压,大大提高了打胶效率和打胶效果。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.
