Abstract
The utility model discloses a sealing rubber strip for a rear door of a refuse collection truck. The sealing rubber strip comprises a mounting part and a sealing part; an internally protruded arc surface and two externally protruded arc surfaces are arranged outside the sealing part; the inner arc surface is arranged on the top of the sealing part; the externally protruded arc surfaces are arranged on the side faces of the sealing part; a capsule hole penetrates through the center of the sealing part; the inner wall of the capsule hole is provided with arc surfaces corresponding to the outside; and the joints of the internally protruded arc surface and the externally protruded arc surfaces are provided with two sealing protrusions. By adopting the penetrating capsule hole structure, the sealing rubber strip is prevented from cracking due to long-term impact, so that the service life of the sealing rubber strip is prolonged; the joints of the internally protruded arc surface and the externally protruded arc surfaces are provided with the two sealing protrusions to improve the sealing property; and the sealing rubber strip can be used for sealing the rear door of the refuse collection truck.
Description
Technical field
The utility model relates to a kind of sealing arrangement, particularly a kind of garbage removing cart backdoor sealing device.
Background technology
Installing and using of door and window; Need all that sealing joint strip is realized between section bar and the glass, the closing seam between fan and frame, door and the frame; Sealing joint strip plays fixing glass in door and window uses; The effect of buffering vibration and blocking-up water, air communication, the heat-insulating property of door and window and air-tightness have significant impact to saving energy and reduce the cost, and the door and window loss of heat loss of poor sealing is 5-6 a times of body of wall loss of heat loss; So adhesive tape to be door and window energy-conservation up to standard in a kind of very important functional accessory, its performance and service life should cause our concern.
The back door sealing of garbage removing cart of the prior art realizes through sealing band that generally said sealing band comprises mounting portion 1 and hermetic unit 2, and said hermetic unit 2 is the sealing cambered surface of cross section semicircular in shape; Because the back door closing system of garbage removing cart is accomplished through the oil cylinder compression, its power is huge, and existing sealing band inside is solid; Under the impact of immense pressure, the inner easy of crack of sealing band is damaged, thereby follows the string; Make its poor sealing performance, service life is short.
The utility model content
The purpose of the utility model provides a kind of garbage removing cart back door sealing joint strip, makes long service life and good sealing effect.
The purpose of the utility model is achieved in that a kind of garbage removing cart back door sealing joint strip; Comprise mounting portion and hermetic unit; Said hermetic unit outer setting has an inner arc surface and two exterior arc surfaces; Said inner arc surface is arranged on the end face of hermetic unit, and said exterior arc surface is arranged on the side of hermetic unit, and said hermetic unit center is run through and is provided with bag hole; Said bag hole inwall is provided with and outside corresponding cambered surface, and said inner arc surface and exterior arc surface junction form two seal convexities.
In the utility model, the bag hole structure that hermetic unit employing center is run through is when the back door is closed; Hermetic unit is under the impact of immense pressure, and two exterior arc surfaces of hermetic unit strut to both sides, have kept the integraty of inner structure; Avoided the cracking of hermetic unit damaged, when opened at the back door, hermetic unit was under elastic reaction; Return under the original form, simultaneously, two seal convexities that inner arc surface and exterior arc surface junction form; Be implemented under the door closure state of back, play the two seals effect.Compared with prior art, the beneficial effect of the utility model is: adopted the bag hole structure to prolong run through service life, two seal convexities of inner arc surface and the formation of exterior arc surface junction have strengthened sealing property.The utility model can be used in the back door sealing of garbage removing cart.
As the further improvement of the utility model, said mounting portion and hermetic unit all adopt ethylene propylene diene rubber to process.Make that it is ageing-resistant, withstanding corrosion, shock resistance, thereby further prolonged its service life.
Description of drawings
Fig. 1 is the utility model structural section figure.
Fig. 2 is a garbage removing cart back door sealing strip structural representation in the prior art.
Wherein, 1 mounting portion, 2 hermetic units, 2a inner arc surface, 2b exterior arc surface, 2c seal convexity, 2d bag hole, 3 section bars.
The specific embodiment
A kind of garbage removing cart back door sealing joint strip as shown in Figure 1; Comprise mounting portion 1 and hermetic unit 2; Hermetic unit 2 outer setting have an inner arc surface 2a and two exterior arc surface 2b, and inner arc surface 2a is arranged on the end face of hermetic unit 2, and exterior arc surface 2b is arranged on the side of hermetic unit 2; Hermetic unit 2 centers are run through and are provided with bag hole 2d; Bag hole 2d inwall is provided with and outside corresponding cambered surface, and inner arc surface 2a and exterior arc surface 2b junction form two seal convexity 2c, and mounting portion 1 all adopts ethylene propylene diene rubber to process with hermetic unit 2.
In the utility model, mounting portion 1 is installed in the section bar 3, the bag hole 2d structure that hermetic unit 2 employing centers are run through; When the back door was closed, hermetic unit 2 was under the impact of immense pressure, and two exterior arc surface 2b of hermetic unit 2 strut to both sides; The integraty that has kept inner structure has avoided the cracking of hermetic unit 2 damaged, when open at the back door; Hermetic unit 2 returns under the original form, under elastic reaction simultaneously; Two seal convexity 2c that inner arc surface 2a and exterior arc surface 2b junction form are implemented under the door closure state of back, play the two seals effect; Adopt ethylene propylene diene monomer (EPDM) material, make that it is ageing-resistant, withstanding corrosion, shock resistance, thereby prolonged its service life.
The utility model is not limited to the foregoing description; On the basis of the disclosed technical scheme of the utility model; Those skilled in the art is according to disclosed technology contents; Do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the protection domain of the utility model.
