DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0025] The utility model provides a kind of print head anti-collision protective shell, as shown in Figure 1 、 Figure 2 And Figure 3 , including print head body 1, the side surface of print head body 1 is slidably connected with anti-collision shell 4, the side surface of anti-collision shell 4 is fixedly connected with insertion column 10, the side surface of print head body 1 is respectively provided with first mounting shell 2 and second mounting shell 3, the side surface of anti-collision shell 4 is respectively slidably attached with the inner wall of first mounting shell 2 and second mounting shell 3, first mounting groove 7 is formed in first mounting shell 2 and second mounting shell 3, electric push rod 8 is fixedly connected in the inside of first mounting groove 7, the movable end of electric push rod 8 is fixedly connected with moving frame 9, the side surface of moving frame 9 is slidably attached with the inner wall of first mounting groove 7, and insertion column 10 is inserted into the inside of moving frame 9.
[0026] The side of print head body 1 is fixedly connected with mounting plate 5, clamping groove that is adapted to mounting plate 5 is formed in first mounting shell 2 and second mounting shell 3, rubber pad 6 is fixedly connected with the inner wall of first mounting shell 2 and second mounting shell 3, and the inner wall of rubber pad 6 is attached with the side surface of print head body 1.
[0027] The main body of the anti-collision protective shell is divided into three parts, namely the first mounting shell 2, the second mounting shell 3 and the anti-collision shell 4, wherein the main body parts of the first mounting shell 2 and the second mounting shell 3 are substantially the same, and the two can be spliced together. When the anti-collision protective shell is used, the anti-collision shell 4 needs to be sleeved on the bottom of the print head main body 1 from bottom to top first, and then the first mounting shell 2 and the second mounting shell 3 are installed on the side surface of the print head main body 1. When installing, attention should be paid to inserting the insertion column 10 on the anti-collision shell 4 into the inside of the moving frame 9, and at the same time, the first mounting shell 2 and the second mounting shell 3 are spliced together. At this time, the first mounting shell 2, the second mounting shell 3 and the anti-collision shell 4 form a complete shell. The first mounting shell 2 and the second mounting shell 3 are used to provide support for the anti-collision shell 4. Since the insertion column 10 is inserted into the inside of the moving frame 9, the anti-collision shell 4 can be controlled to move by the electric push rod 8. When the printer is not used, the electric push rod 8 can drive the anti-collision shell 4 to move downward through the moving frame 9, thereby protecting the print head main body 1. When the printer is used, the electric push rod 8 can be retracted, so that the anti-collision shell 4 moves upward to fit the print head main body 1, so as to expose the bottom part of the print head main body 1, so that it can contact the printing paper.
[0028] The staff can install the print head main body 1 in the inside of the printer through the mounting plate 5. The first mounting shell 2 and the second mounting shell 3 are both provided with clamping grooves matched with the mounting plate 5. When the first mounting shell 2 and the second mounting shell 3 are installed, the clamping grooves need to be aligned with the mounting plate 5, so that the mounting plate 5 is clamped in the inside of the clamping grooves. After the first mounting shell 2 and the second mounting shell 3 are spliced together, the mounting plate 5 can provide good support for them, ensuring that they can stably serve the anti-collision shell 4. In addition, the rubber pad 6 provides a buffering effect between the first mounting shell 2 and the second mounting shell 3 and the print head main body 1. This setting can reduce the knocking between the first mounting shell 2 and the second mounting shell 3 and the print head main body 1 when the first mounting shell 2 and the second mounting shell 3 are installed, which helps to improve the service life of the print head main body 1.
[0029] Further, in order to improve the firmness when the first mounting shell 2 and the second mounting shell 3 are spliced together, as shown in Figure 2 , Figure 3 , Figure 4 and Figure 6 , the two sides of the first mounting shell 2 are fixedly connected with fixed shells 11, and the two sides of the second mounting shell 3 are fixedly connected with insertion rods 12. The inside of the fixed shell 11 is provided with a first insertion slot for inserting the insertion rod 12.
[0030] The inside of the fixed shell 11 is provided with a second mounting groove 13 which is communicated with the first slot, and the inside of the second mounting groove 13 is slidably connected with a clamping block 14 which extends to the inside of the first slot, and the bottom of the clamping block 14 is fixedly connected with a spring 15, and the bottom end of the spring 15 is fixedly connected with the inner wall of the bottom of the second mounting groove 13, and the plug rod 12 is provided with a second slot which is matched with the clamping block 14.
[0031] The side of the fixed shell 11 is provided with a sliding groove which is communicated with the second mounting groove 13, and the inside of the sliding groove is movably connected with a push rod 16, and one end of the push rod 16 is fixedly connected with one side of the clamping block 14.
[0032] When the first mounting shell 2 and the second mounting shell 3 are spliced together, the plug rod 12 will be inserted into the inside of the first slot, and the plug rod 12 will be in contact with the curved surface of the clamping block 14 and press the clamping block 14 during the process of entering the inside of the first slot, so as to force the clamping block 14 to slide downward in the inside of the second mounting groove 13, and the clamping block 14 can compress the spring 15 when it moves downward, and when the plug rod 12 is in contact with the inner wall of the first slot, it means that the plug rod 12 has completely entered the inside of the first slot, and at this time the second slot on the plug rod 12 is just aligned with the second mounting groove 13, and the spring 15 can quickly recover to the initial state after losing pressure, and push the clamping block 14 to move upward, so that the clamping block 14 is inserted into the second slot, thereby limiting the movement of the plug rod 12, and thus the first mounting shell 2 and the second mounting shell 3 can be stably spliced together, and when disassembling the first mounting shell 2 and the second mounting shell 3, the push rod 16 can be pushed downward, and the push rod 16 is connected with the clamping block 14 and can drive the clamping block 14 to move, so that the clamping block 14 moves out of the inside of the second slot, thereby releasing the fixed plug rod 12, and then the first mounting shell 2 and the second mounting shell 3 can be directly separated.
[0033] Further, in order to improve the practicability of the anti-collision protective shell, as shown in Figure 1 , Figure 2 and Figure 5 , the bottom of the anti-collision shell 4 is fixedly connected with a mounting frame 17, and a plurality of pressing rollers 18 are rotatably connected with the mounting frame 17.
[0034] The plurality of pressing rollers 18 can rotate on the mounting frame 17 and are linearly arrayed, and when using the printer, the electric push rod 8 needs to drive the anti-collision shell 4 to move upward to fit the print head main body 1 to expose the bottom part of the print head main body 1, and at this time the bottom of the pressing roller 18 is flush with the bottom of the print head main body 1, and this arrangement can assist the movement of the printing paper, and has high practicability in actual use.
[0035] It should be noted that the anti-collision protective shell adopts the electric push rod 8 which is the type of extension in power-off. The push rod can automatically extend in the case of power-off, which is the prior art and will not be explained in detail. In the case of power-off, the electric push rod 8 can automatically drive the anti-collision shell 4 to move downward, thereby protecting the print head main body 1.
[0036] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
