Description

Eraser fixing device

Technical field

It the utility model is related to a kind of eraser fixing device.

Background technology

Erasing rubber species now is various, to suit different needs, there is common erasing rubber, also have drawing HB, 2B, The fine arts special eraser of the models such as 4B, 6B, and plastic rubber etc., it is necessary to which different shaped is frequently used alternatingly when in drawing Number erasing rubber, to modify to works, and the erasing rubber of scattered placement is not only not easy searching needs model, but also easily Lose.

The content of the invention

, can be by various types of rubbers the technical problem to be solved by the present invention is to provide a kind of eraser fixing device Skin is wiped and is fixed together, and is found and is used easy to people.

In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of eraser fixing device, including side Pipe, be respectively equipped with square tube both ends one group of erasing rubber fixation kit and with the matched card-tight part of rubber brush assembly；

Card-tight part includes two inclined-planes for being separately positioned on square tube inner wall both sides and two are arranged on square tube outer wall both sides Counterbore, a tubaeform gap wide outside and narrow inside is formed by two inclined-planes in square tube；

Fixation kit includes pressing clip and two pieces of wedge blocks, and two pieces of wedge blocks are attached on two inclined-planes of card-tight part respectively, rubber Skin brush assembly is sandwiched between two pieces of wedge blocks, and square tube is exposed in wedge block upper end；

Pressing clip is made of square frame and two pieces of spring bearer plates for being separately fixed at square frame both ends, in two block pressur plate opposite ends It is raised that one is respectively equipped with face；Square frame is sleeved on outside rubber brush assembly, and is pressed on wedge block, and two side guide of square frame is respectively positioned at side Pipe both sides, two protrusions are respectively inserted into two counterbores in card-tight part.

One piece of transverse slat is fixedly arranged in the middle of in square tube, one piece of top plate is respectively equipped with transverse slat both sides, top plate passes through more springs It is connected with transverse slat.

The beneficial effects of the utility model are：Various types of erasing rubbers can be fixed using fixation kit and card-tight part Together, in order to which people find and use, drawing efficiency is improved, and it is simple in apparatus structure, it is easy to use.

Brief description of the drawings

The utility model is described further below in conjunction with the accompanying drawings：

Fig. 1 is the cross-sectional view of the utility model,

Fig. 2 is the utility model overlooking the structure diagram,

Fig. 3 is the utility model left view structural representation,

Fig. 4 is the partial enlargement structural representation at A in Fig. 1,

Fig. 5 is the cross-sectional view at B-B in Fig. 3.

In figure：Square tube 1, wedge block 2, transverse slat 3, pressing clip 4, spring 5, top plate 6, rubber brush assembly 7, inclined-plane 11, counterbore 12nd, square frame 41, pressing plate 42, protrusion 43.

Embodiment

As shown in Fig. 1 to 5, a kind of eraser fixing device, including square tube 1, it is respectively equipped with one group of rubber at 1 both ends of square tube Wipe fixation kit and with 7 matched card-tight part of rubber brush assembly；

Card-tight part includes two inclined-planes 11 for being separately positioned on 1 inner wall both sides of square tube and two are arranged on 1 outer wall two of square tube The counterbore 12 of side, a tubaeform gap wide outside and narrow inside is formed by two inclined-planes 11 in square tube 1；

Fixation kit includes pressing clip 4 and two pieces of wedge blocks 2, and two pieces of wedge blocks 2 are attached to two inclined-planes 11 of card-tight part respectively On, rubber brush assembly 7 is sandwiched between two pieces of wedge blocks 2, and square tube 1 is exposed in 2 upper end of wedge block；As shown in Figure 1, erasing rubber Component 7 is made of two pieces of erasing rubbers being arranged side by side；

Pressing clip 4 is that the spring bearer plate 42 that 41 both ends of square frame are separately fixed at by square frame 41 and two pieces is formed, in two pieces of pressures A protrusion 43 is respectively equipped with 42 opposing end surface of plate；Square frame 41 is sleeved on outside rubber brush assembly 7, and is pressed on wedge block 2, square frame 41 Two side guides 42 are located at 1 both sides of square tube respectively, and two protrusions 43 are respectively inserted into two counterbores 12 in card-tight part, pressing clip 4 are made of ABS plastic, can be appropriately curved.

In use, two pieces of wedge blocks 2 will can be respectively first attached to 7 both sides of rubber brush assembly, then by two wedge blocks 2 It is inserted into together in square tube 1 with rubber brush assembly 7, then square frame 41 is sleeved on outside erasing rubber, two protrusions 43 is attached to respectively at this time On 1 both sides outer wall of square tube, pressing plate 42 bend slightly outwards, then firmly press down on square frame 41, force two pieces of wedge blocks 2 by rubber Skin brush assembly 7 is clamped, and with the downlink of square frame 41, two protrusions 43 are entrapped in two counterbores 12, utilizes raised 43 Hes Counterbore 12 realizes the clamping to rubber brush assembly 7 so that square frame 41 to be fixed.

One piece of transverse slat 3 is fixedly arranged in the middle of in square tube 1, is respectively equipped with one piece of top plate 6 in 3 both sides of transverse slat, top plate 6 passes through more Spring 5 is connected with transverse slat 3.

After rubber brush assembly 7 is inserted into square tube 1, spring 5 promotes top plate 6 to be resisted against two pieces of erasing rubber lower faces On, avoid in use because erasing rubber is slided into square tube 1, and influence people's use.
