Detailed Description

The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.

As shown in fig. 1-5, the present invention provides a displacement structure of a manual glue gun, which comprises a displacement cabin 1 and a displacement assembly 2;

the displacement assembly 2 comprises a spring 21, a shifting piece 22 and a force bearing barrel 23, wherein the spring 21 comprises a return spring 210 and a clamping spring 211, the shifting piece 22 is a block-shaped body provided with a through hole, and the shifting piece 22 comprises a driving piece 220 and a braking piece 221;

the retaining spring 211 is located in the force bearing cylinder 23, and the return spring 210, the driving plate 220, the force bearing cylinder 23 and the braking plate 221 are coaxially arranged in sequence to form a group of displacement assemblies 2;

the displacement cabin 1 is a cabin with an open top, coaxial through holes 101 are formed in two opposite side walls of the displacement cabin 1, the displacement assembly 2 is arranged in the displacement cabin 1, and the through holes 101 are the same as the axis of the displacement assembly 2.

Through holes 101 matched with the displacement assembly 2 are formed in the front and the back of the displacement cabin 1, the through hole 101 located at the position of the return spring 210 is marked as a left through hole, the through hole 101 located at the position of the brake block 221 is marked as a right through hole, and when a guide rod of the manual glue gun penetrates through the right through hole of the displacement cabin 1 and then sequentially passes through all components of the displacement assembly 2, the guide rod penetrates through the left through hole of the displacement cabin 1, wherein on one hand, the diameter of the guide rod of the manual glue gun is slightly smaller than that of the through hole 101, the driving plate 220, the brake block 221, the return spring 210 and the clamping spring; on the other hand, the length of the retaining spring 211 is slightly longer than that of the bearing cylinder 23.

By applying a horizontal external force F to the direction of the return spring 210 from above or below the driving plate 220, the driving plate 220 is inclined by the horizontal external force F, because the driving plate 220 is connected with the guide rod in a matching way, the gap is small, the inclined driving plate 220 is pressed with the guide rod, thereby generating a frictional thrust F for pushing the guide rod to move forward, at this time, the inclined driving plate 220 simultaneously presses the lower part or the upper part of the bearing cylinder 23 which is adjacent to the rear part, if the horizontal external force is applied from below the driving plate 220, the bearing point of the bearing cylinder 23 is above, and if the horizontal external force is applied from above the driving plate 220, the bearing point of the bearing cylinder 23 is below, in short, the brake plate 221 is inclined by the conduction of the unilateral force of the bearing cylinder 23, thereby generating a certain frictional resistance F' with the guide rod, because the horizontal external force is directly applied on the driving plate 220, therefore, the friction thrust f generated by the driving plate 220 and the guide rod is greater than the friction resistance f' generated by the braking plate and the guide rod, and the guide rod can move towards the return spring 210;

when the horizontal external force F stops, the reaction force of the return spring 210 pushes the driving plate 220 to move back, at this time, the driving plate 220 still keeps a certain inclined extrusion relationship with the guide rod, so that the driving plate 220 continues to keep the single-point acting force with the force bearing cylinder 23, and at the same time, the driving plate 220 compresses the clamping spring 211 in the process of moving back, therefore, the forces of the clamping spring 211 and the force bearing cylinder 23 are simultaneously applied to the braking plate 221, the braking plate 221 and the guide rod generate a frictional resistance F ' ″ which is opposite to the direction of a reverse frictional driving force F ' generated by the driving plate 220 and the guide rod, but F ' ″ is greater than F at this time, so that the braking plate 221 plays a stopping role, namely, the moving back of the guide rod is prevented.

After the return spring 21 pushes the driving plate 220 to return to the proper position, the contact between the driving plate 220 and the force-bearing cylinder 23 changes to the vertical direction, the force-bearing cylinder 23 receives the force in the horizontal direction, and then the horizontal force is transmitted to the brake pad 221, so that the brake pad 221 returns to the proper position, and the brake pad 221 which is inclined with the guide rod returns to the vertical state, and the squeezing friction resistance between the brake pad 221 and the guide rod is also eliminated, thereby ensuring that the guide rod does not move back due to the action of the friction driving force f' of the driving plate 220 and the guide rod.

Therefore, horizontal pushing force is applied to the pushing sheet 220 in a reciprocating mode, so that the guide rod of the manual glue squeezing gun can be guaranteed to continuously advance forwards, and glue can be squeezed.

The number of the driving plates 220 in each set of the displacement assemblies 2 is 2, and the number of the braking plates 221 in each set of the displacement assemblies 2 is 2.

When the driving plate 220 and the braking plate 221 in the displacement assembly 2 are set to be single, because the point of the extrusion friction between the driving plate 220 and the guide rod is the same position in the using process, the abrasion loss at the position where the driving plate 220 and the guide rod generate friction is increased after a period of use, which leads to the increase of the gap between the driving plate 220 and the guide rod, and the driving plate 220 becomes smooth due to frequent friction, in both cases, the friction driving force between the driving plate 220 and the guide rod is reduced, and the slipping is generated in the using process, even the normal work cannot be performed. When the driving sheet 220 is changed from single to two which are overlapped together, when a horizontal external force is applied, the contact surface between the driving sheet 220 and the guide rod is enlarged, the friction driving force generated by the driving sheet and the guide rod is multiplied, the driving force can be greatly increased, the two friction driving forces f can be complemented because the two friction driving forces f in the same direction are generated in the horizontal direction, and when one of the two friction driving forces f is reduced, the other friction driving force can be complemented, so that the phenomenon that the guide rod slips is prevented. Similarly, the arrangement of the brake plate 221 is changed from single to two, and is the arrangement matched with the driving plate 220, so that the excessive force in the process of moving back the driving plate 220 is prevented, and the brake plate cannot play a role of an effective stop.

The bearing cylinder 23 is a conical cylinder body, and the cross-sectional area of the bearing cylinder 23 in contact with the driving plate 220 is smaller than the cross-sectional area of the bearing cylinder 23 in contact with the brake plate 221.

The shape of the force bearing cylinder 23 can be a straight cylinder or a square, preferably a cone-shaped cylinder, and the sectional area of one end of the cone-shaped force bearing cylinder 23, which is in contact with the driving plate 220, is smaller than that of the other end, at this time, the force bearing cylinder 23 can transmit the force transmitted from the driving plate 220 to the brake pad 221 at a certain angle of upward or downward inclination, and because the contact point of the force bearing cylinder 23 and the brake pad 221 is higher, the brake pad 221 can be changed into an inclined state in a labor-saving manner according to the lever principle, so as to achieve the purpose and effect of effective stopping.

The displacement cabin 1 comprises two groups of displacement assemblies 2, the two groups of displacement assemblies 2 are arranged in parallel in the same direction, a U-shaped groove 102 is formed in a wall plate of the displacement cabin 1 between the two groups of brake pieces 221, a cross rod 103 is arranged below an opening in the upper end of the U-shaped groove 102, a limiting plate 3 is arranged between each brake piece 221 and the wall plate of the displacement cabin 1, the two groups of brake pieces 221 are symmetrically attached to two sides of the limiting plate, the cross rod 103 is rotatably connected with a limiting handle 4, and the limiting handle 4 is in contact with the limiting plate 3 and used for pushing the limiting plate 3 to move towards the driving piece 220.
