Description

Technical Field

[0001] The invention relates to a suspension fixing frame for a vehicle-mounted shelter or a military container shelter, and belongs to the category of a container-integrated tooling fixture device. Background Art

[0002] At present, how to pack more containerized materials and equipment in a limited space and maximize the utilization of space, people have been seeking better ways and means to achieve it. With the widespread application of container integration technology, container integration technology has been extended from fixed equipment to movable cabins to vehicle-mounted cabins, and from static to movable to driving state. When used for military cabin container integration, the container device tilts 30° with the cabin during self-loading and unloading operations, and its container technology must also adapt, and the requirements for container devices are getting higher and higher.

[0003] The general method is to use a fixed frame to fix the container equipment in the cabin, which does not make good use of the space and does not have a reliable and convenient locking mechanism at the extreme position, which affects the use of the container cabin. In addition, the container equipment is loaded on a flat pull-out frame, which cannot meet the needs of loading more container equipment in a narrow space. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and to provide a vertical telescopic suspension fixing frame for a vehicle-mounted shelter. When the space is narrow, the containerized equipment and devices can be fixed on the left and right sides of the vertical telescopic suspension fixing frame to facilitate storage and removal.

[0005] The technical solution of the present invention is: it includes a frame, an upper / lower guide rail, and a locking mechanism for locking the position of the frame on the upper / lower guide rail. The frame is connected between the upper / lower guide rails via a guide rail slide nut and a support guide wheel assembly; the locking mechanism includes a locking mechanism latch and an inclined limit block corresponding to the extreme position of the frame, a compression spring is arranged in the locking mechanism latch, and a limit through hole is arranged in the middle of the inclined limit block. The locking mechanism also includes a brake soft steel wire pull rope and a knob for driving the locking mechanism latch in / out of the limit through hole, and the knob is connected to the locking mechanism latch via the steel wire pull rope; the support guide wheel assembly includes an upper / lower support double guide wheel arranged at the front of the upper / lower guide rail groove, and transverse guide wheels arranged on both sides of the front of the upper / lower guide rail.

[0006] A handle is provided in the front of the frame, and the knob is inserted into the mounting hole on the frame in the middle of the handle. One end of a soft steel wire rope for braking is connected to the knob, and the middle part of the steel wire rope is passed through the middle part of the frame. The other end of the steel wire rope is connected to a locking mechanism pin, and the locking mechanism pin is located on the lower left side of the rear part of the frame.

[0007] Plastic stoppers are arranged at the front and rear ends of the upper / lower guide rail groove.

[0008] The frame is provided with a rack parallel to the upper / lower guide rails, a gear matched with the rack is mounted on the rotating shaft of the brushless motor, and the brushless motor is mounted on the upper guide rail.

[0009] The guide rail slide nut is provided with a guide rail slide nut connecting plate connected to the upper / lower left and right side surfaces of the rear part of the frame.

[0010] The transverse guide wheels are installed on the left and right sides of the front of the upper / lower guide rails through the transverse guide wheel support plates, and the surfaces of the transverse guide wheels correspond to the left and right sides of the frame; the upper / lower supporting double guide wheels are installed on the front of the upper / lower guide rail grooves through the double guide wheel support plates, and the surfaces of the upper / lower supporting double guide wheels correspond to the upper and lower sides of the frame respectively.

[0011] The frame is a vertical frame, which is formed by splicing horizontal and vertical aluminum profiles.

[0012] The upper / lower guide rails are installed on a vehicle-mounted shelter or a military container shelter.

[0013] There are two inclined surface limit blocks, which are arranged on the left side of the lower guide rail.

[0014] The inclined surface limiting block comprises a plane and an inclined surface connected to the plane, the limiting through hole is arranged on the plane, and the inclined surfaces of the two inclined surface limiting blocks are arranged opposite to each other.

[0015] Explanation of the name of the present invention: The vehicle-mounted shelter refers to the present invention being applicable to all-round and all-terrain occasions, including driving and self-loading and unloading processes. Vertical means that the fixed frame is placed upright, and the container parts can be hung on the left and right, and can be telescopic forward and backward. Telescopic means that the vertical fixed frame can be pulled outward and pushed back inward when hanging the container parts. Suspension means that the container parts and the cargo bucket are suspended on the vertical fixed frame. The fixed frame is a skeleton used to carry and fix objects.

[0016] The present invention is vertically standing, and the frame can slide and retract along the upper / lower guide rail slide nut. The containerized equipment parts can be hung on the vertical frame, and the storage box can also be hung. The present invention can be installed in the same direction as the driving direction of the vehicle-mounted cabin, and can also be installed and used in a direction perpendicular to the driving direction.

[0017] When the vertical frame slides to the limit position along the guide rail slide nut, the rear end and front end of the guide rail slide nut elastically collide with the plastic stops fixed at the rear and front parts of the guide grooves of the upper / lower guide rails to stop sliding, and the plastic stops play a role of limiting buffering; at the same time, the locking mechanism pin of the locking mechanism fixed at the lower left side of the rear part of the vertical frame slowly slides from the inclined surface of the inclined limit stopper fixed at the inner end and front end of the upper / lower guide rails to its limiting through hole, which plays a role of limiting the forward and backward sliding of the vertical frame.

[0018] The present invention is applied to the suspension of containerized materials and equipment in a vehicle-mounted container or a military container container, which is often in the retracted limit locking state of the inner end. The suspended materials and equipment are assembled in the vehicle-mounted container container through the present invention; when the vehicle-mounted container container is in the process of driving or the container is pulled from the ground to the vehicle by the working vehicle, the present invention can withstand the front and rear inertial forces and bumping forces during transportation or the 30° tilting force of the military container container when it is pulled to the working vehicle; when the vehicle-mounted container and the military container are parked during driving or if the containerized equipment is to be taken out of the military container on the ground, the vertical frame handle can be held by hand, and the middle finger and index finger can be used to pull the knob of the locking mechanism, so that the locking mechanism pin of the locking mechanism is lifted by the brake soft steel wire pull rope to leave the inner end inclined limit block and disengage from its limit through hole, and the vertical frame is pulled to slide along the upper / lower guide rail sliding nut motion pair to extend to the front end extension limit state. , the front end of the plastic stopper limit rail slide nut at the front part of the upper / lower guide groove is provided, which plays a role of limit buffer limit. At the same time, the locking mechanism pin slides into its limit through hole along with the inclined surface of the front inclined surface limit block, limiting the relative movement of the vertical frame, so that the equipment suspended on the left and right sides can be conveniently taken and placed; if the vertical frame needs to be retracted to the inner end limit position, the handle on the vertical frame is still held, and the middle finger and index finger pull the knob of the locking mechanism, so that the locking mechanism pin of the locking mechanism is lifted by the brake soft steel wire rope to leave the front end inclined surface limit block and disengage from its limit through hole, pushing the vertical frame to slide back to the innermost retraction limit state along the upper / lower guide rail slide nut motion pair, and the rear end of the plastic stopper limit rail slide nut at the rear part of the upper / lower guide groove is provided, which plays a role of limit buffer limit. At the same time, the locking mechanism pin slides into its limit through hole along the inclined surface of the inner end inclined surface limit block, limiting the relative movement of the vertical frame.

[0019] No matter in the two extreme positions of the inner end and the front end or in the extension and retraction process, the lower supporting double guide wheels of the front end groove of the lower guide rail bear the support and pressure of the vertical frame. The maximum support position is the contraction limit state, and the maximum pressure is the extension limit position. The upper supporting double guide wheels of the front end groove of the upper guide rail limit the upward movement of the vertical frame; the lateral sliding support wheels on both sides of the front of the upper / lower guide rails limit the vertical frame from swinging back and forth, and the maximum swing position is the contraction limit state, that is, the storage and transportation state.

[0020] When the frame is set perpendicular to the direction of movement, the guide rail nut and the lower support double guide wheels bear a larger force in the direction of movement in the limit state of retraction. If it is set longitudinally to the direction of movement, the locking mechanism pin bears a larger force in the limit state of retraction. When braking or accelerating suddenly or climbing a steep slope during driving, the fixed frame completely relies on the locking mechanism pin to bear all forces including inertia.

[0021] During the driving process of the car, the inertial force of the container equipment located in the vehicle-mounted square cabin is mainly the inertial force in the front and rear directions of the car, and the inertial force in the left and right directions of the car is relatively not large. The frame of the present invention is a vertical frame, which is perpendicular to the direction of movement of the car. The upper / lower guide rail rear end guide rail sliding mother motion pair and the transverse guide rail supporting the guide wheel assembly of the present invention bear the large inertial force of the front and rear directions of the car. The locking mechanism pin located on the lower left side of the frame bears the relatively small inertial force in the left and right directions of the car, which prolongs the service life of the locking mechanism pin. At the same time, during the driving process of the car, the vertical frame of the present invention also bears the left and right inertial force of the car, which makes it easy for the present invention to shake back and forth between the upper / lower guide rails. By setting plastic blocks at the front and rear ends of the upper / lower guide rail groove, the shaking amplitude of the vertical frame is reduced, so that the structure of the present invention is more stable and reliable, suitable for use in various harsh outdoor environments, and has a long service life.

[0022] The vertical frame is extended and retracted by a brushless motor driving the gear to drive the rack to achieve linear motion, and it can also be extended and retracted manually. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] Figure 1 , 2, 3, the present invention is composed of a vertical frame 1, upper and lower guide rail slides 2, a locking mechanism 3, a support stopper component 4, a gear 11, and a rack 10. The vertical frame 1 is spliced ​​by horizontal and vertical aluminum profiles. The upper and lower left and right sides of the rear of the upper and lower horizontal aluminum profiles are connected to the guide rail slide nut 2 through a guide rail slide nut connecting plate. The side of the upper horizontal aluminum profile is used to install the rack 10. The front is supported by a supporting guide wheel assembly. A warning light 7 is provided on the upper part of the front longitudinal aluminum profile, a handle is provided in the middle and lower part, and a locking mechanism knob 8 is provided in the middle of the handle. The knob 8 is connected to the tail locking mechanism pin 4 through a brake soft steel wire pull rope 6 in the middle and lower part of the corresponding horizontal profile. The upper and lower guide rail slides 2 are composed of an upper / lower guide rail slide pair, a linear guide motion pair, and a connecting fixed plate. The upper / lower guides are fixed to the vertical frame 1 through the connecting fixed plate and form a vertical frame relative to the guide rail sliding motion pair with the slide nut.

[0029] The locking mechanism 3 is composed of a knob 8, a soft steel wire rope 6 for brake, a locking mechanism latch 4, and an inclined limit stopper 5. One end of the soft steel wire rope 6 for brake is connected to the knob 8, and the other end of the soft steel wire rope 6 for brake is connected to the locking mechanism latch 4. The middle part of the soft steel wire rope 6 for brake is installed in the aluminum profile in the middle part of the vertical frame 1. The locking mechanism latch 4 is installed in the longitudinal aluminum profile at the rear of the vertical frame 1. A compression spring is arranged inside the locking mechanism latch 4 to make the locking mechanism latch 4 receive downward force. The inclined limit stopper 5 is fixed at the two extreme ends on the left side of the lower guide rail. A limit through hole is arranged in the middle of the inclined limit stopper 5, which corresponds to the extreme position of the locking mechanism latch 4. When the vertical frame 1 is fixed, it slides to the extreme position of the end through telescopic movement, and the inclined surface of the inclined limit stopper 5 makes the locking mechanism latch 4 automatically insert into the limit hole to play a locking role. If it is necessary to push the fixed vertical frame, the knob 8 is pulled back, and the locking mechanism latch 4 is pulled upward through the soft steel wire rope 6 for braking. At this time, its compression spring is compressed, and the locking mechanism latch 4 is withdrawn and leaves the limit through hole. At this time, the vertical frame can be pushed.

[0030] The support stopper component is composed of an upper support double guide wheel arranged at the front end groove of the upper guide rail, a lower support double guide wheel 14 arranged at the front end groove of the lower guide rail, a plastic stopper 9 at the front and rear grooves of the upper / lower guide rails, and a transverse sliding support wheel 13 arranged at both sides of the front of the upper / lower guide rails. The upper / lower support double guide wheels support the front of the upper and lower transverse profiles of the vertical frame 1, and play a supporting and guiding role for the vertical frame 1 corresponding to the guide rail slide nut 2. The transverse sliding support wheel 13 used in pairs plays a role in supporting the side of the upper and lower transverse profiles of the vertical frame. When the vertical frame 1 slides and retracts, the lower support double guide wheel 14 plays a role in rolling and upward support, the upper support double guide wheel plays a role in rolling, and the transverse sliding support wheel 13 plays a role in left and right support and rolling. When the vertical frame 1 slides and extends to the extension limit position at the far end, under the action of the gravity of the equipment being assembled, the lower support double guide wheel bears the maximum upward support force. When the vertical frame 1 is retracted to the retracted limit position and fixed, the transverse sliding support wheel 13 plays a maximum state of left and right support. Two plastic blocks are arranged at two extreme positions of the vertical frame 1, which play a role in limiting and buffering the guide rail slide nut 2 when the vertical frame 1 slides to the extreme position, thereby achieving the limit of the vertical frame. When the vertical frame is telescoped to the extreme position and hits the plastic block, it stops, and the locking mechanism pin of the locking mechanism slowly slides upward along the inclined surface of the inclined limit block 5 to the limit through hole, thereby achieving the consistent effect of the three.

[0031] The brushless motor 12 is relatively fixed to the upper guide rail, the gear 11 is sleeved on the rotating shaft of the motor, and the rack 10 is installed on the side of the vertical frame 1. The gear 11 and the rack 10 are meshed to form a gear-rack kinematic pair. When the brushless motor 12 drives the gear 11 to rotate, the rack 10 is driven to move along the tangential direction of the gear 11.
